Analysis of defects in welding of metal materials and discussion of countermeasures

  Metal has a very distinctive feature is weldability. The so-called metal welding is a process that uses heating, high temperature or high pressure to produce molecules or atoms from two metal objects that are not together and united together. When it comes to metal welding methods are also characterized by diversity, the use of each method has its own advantages and disadvantages and different effects [1], which is attracting increasing attention.

  1 Defects in the welding of metallic materials

  1.1 The emergence of welding cracks

  In the welding of metals, there is a relatively common situation is cracking, and cracking is mainly the difference between the crystalline state of the mutual changes that arise. The appearance of cracks is not very long, sometimes immediately visible or stop a moment that is visible, and its location is often in the welding base material and the junction of the fusion line, cold and hot is the main classification of cracks.

  Hot cracking is basically occurs at the position of deviation. Its formation is mainly due to the impurity crystals left in the melt pool with low melting point and high freezing point and low strength, which are easily pulled apart when they are bound due to the many defects of these impurity crystals, which is the formation process of thermal cracking. In contrast to this cold cracking, first of all, in time on the hot cracking is late, during or after welding, and when the low temperature descends there will be cracks, and even some cold cracks appear time is more lagging, only after a few days, such a situation will be very easy to affect the normal use of structural safety

  1.2 The emergence of non-welding, non-fusion phenomenon

  When the metal is not all welded to the deepest part of the joint, that is, the root, resulting in the wood metal can not be completely melted away, thus causing is called not welded through, its main target is the wood. The disadvantages of this situation, which is not welded through, are numerous, frequently making the effective area of the weld gradually smaller and weakening the strength of the joint, and finally leading to a continuous decline in the fatigue strength of the weld. Another situation that is similar to unwelded is unfused, as the name implies, there is no perfect fusion between the metal joint, which brings the defect of reducing the bearing area, making it very difficult to gather stress

  1.3 The appearance of slag situation

  In the welding process there will be some residue left behind in the weld, we can call it in short slag. There are many reasons for the formation of slag, for example, when the current strength is not enough or large or small, welding speed or slow, unreasonable choice of welding rod, the bevel angle is not appropriate or the welding rod bias core and other reasons will make the edge of the weld left slag.

  1.4 The appearance of other defects

  (1) The weld organization may not meet the requirements, or because it fails to meet the standard chemical composition, and there is also the instability of the chemical composition of the weld metal caused by elemental burnout that occurs during welding. All of this will continue to weaken the mechanical capacity of the weld, thus more seriously making the corrosion resistance of the joint also suffered.

  (2) Bite edge also occurs in the welding process, mainly due to high current or unsuitable welding rod angle reseal the weld edge of the crater is not well in the first time to fill the metal and caused. This phenomenon may make the use of metal materials greatly reduce the area, along with this also makes the structure to withstand the pressure resistance of this indicator is difficult to meet the requirements, more serious is due to the reaction force is greatly gathered and lead to cracks.

  2 metal material welding in the prevention and control measures

  All kinds of disadvantages are very easy to appear in the welding process of metal materials, so you have to worry about the quality of metal materials, it is clear that when we face these defects, timely and appropriate preventive and control measures are very necessary.

  2.1 Measures to prevent cracking

  Measures to prevent cracking are mainly the following: First, we must strictly comply with the rules associated with it, carefully consider the welding procedures you want to choose, strictly adhere to the standards of the welding rod, carefully identify its acidity and alkalinity, in order to achieve better results can be placed in a stable holding room, when we need to use it out; Second, we must carefully clean the interface to ensure that there is no moisture, oil or Is other traces left behind; Third, when we are during the welding, pay attention to choose a smaller current, and then choose multiple welding channels, a variety of levels to strictly enforce, so it is good to make the chance of cracking greatly reduced, but also to improve the shape of the weld wash, so that the stress of welding is also reduced.

  2.2 Measures to prevent failure to weld through, failure to fuse

  When welding has not yet begun, we have to do some preparatory work, such as a reasonable choice of bevel angle and size, the correct choice of the diameter of the welding rod. Secondly, the current size and welding speed should also be carefully selected. And in the process of welding, we should also pay attention to the proper swing of the chain above and concentrate on observing the changes on both sides. It must be ensured that all processes are carried out in accordance with the correct techniques and in compliance with the construction specifications.

  2.3 Measures to prevent slagging

  The first is to pay special attention to the selection of welding rods, the requirements of which are different for acidic and alkaline welding rods. The second is to have the right bevel angle and to control the welding speed that can not be too fast

  2.4 Strengthening the skills of welders

  Welding is also a certain technical requirements for welders, training in basic skills is necessary, the training content is mainly how to choose the materials to be used and the specific construction environment, and in the welding process should maintain what posture and control are also required to learn further, so that welding work is carried out smoothly without the influence of any external forces, so that the disadvantages can be further reduced. At the same time, the self-control of the welders needs to be further learned. At the same time, the self-control of the welders should be further enhanced, to make each welder qualified, the quality and skills of strict control.

  2.5 Other comprehensive measures

  In addition, we should also pay attention to other comprehensive measures, for example, for the construction environment should also be more requirements, if the temperature is relatively low, we must be certain heating of the materials used, in the construction area should also establish a certain clean area, but to ensure that during the work ventilation, for air humidity as far as possible to less than 90%, and to ensure that the concentration of argon gas to more than 99% and so on. A series of measures.

  3 Conclusion

  While the economy is developing rapidly, industry still occupies an important and indestructible position, which undoubtedly brings about the widespread use of metals, which increasingly has an important impact on daily production life. The popularity of metal has also led to the increasingly accelerated development of welding technology, however, through this article we can clearly understand that there are various disadvantages of metal welding, it will be directly to the detriment of the welded structure, or even serious harm to people’s personal safety.

Therefore, no matter what is its starting point, we have to overcome all the shortcomings to the greatest extent possible, the development and implementation of a variety of measures to put forward higher requirements for welders, and constantly develop better welding methods, so that the welding quality gradually climb.

Analysis of concrete pumping technology application for super high-rise buildings

  0Introduction

  Super high-rise buildings are constantly developing, and at the same time, the construction technology of high-rise buildings and super high-rise buildings is constantly improving, among which, the pumped concrete construction technology of super high-rise buildings is very rapid from generation to development. Pumped concrete technology, which uses concrete pumps and pipelines to transport concrete to the construction point of high-rise floors, has quickly become an essential and important means of concrete construction in super high-rise buildings because of the advantages of fast transportation speed, high transportation capacity and high efficiency.

The article discusses the importance of concrete pumping construction technology for super high-rise buildings, introduces various problems, and proposes effective strategies for these problems.

  1 Project overview

  In a project in Guangzhou, the underground part is mainly divided into four independent towers, three of which are extra-barrel slab and core structure. Barrel outside the floor structure, mainly by reinforced concrete column one as well as steel beam composition. The barrel structure and the reinforced concrete part are made of high strength concrete ranging from C40 to C60, and the strength of the concrete used for the outer barrel slab is C30.

According to the specific construction conditions of this project, the construction plan was set to construct the barrel of each tower first, and then pour the outer barrel slab and reinforced concrete columns. The barrel material as mentioned above is a relatively high strength concrete, the content of cement in the concrete will be more than the low strength concrete, and the viscosity is also more than the viscosity of low strength concrete, so when pumping concrete to the upper floors, the resistance will be larger, which increases the technical requirements of pumping concrete construction.

In addition, the curved shear wall columns, reinforced concrete columns and other structures included in the cylinder structure, as well as the relatively large diameter reinforcement and the dense arrangement of nodal reinforcement, all greatly increased the difficulty of concrete placement. The total height of the project reached 334 meters, of which the pumping height reached 326 meters, such a height for the pumping of concrete construction technology requirements are more challenging. According to the above mentioned key points and difficulties in the process of pumping construction of this project, it is necessary to improve the construction technology to meet the quality requirements of construction.

  2 Material Selection and Concrete Mixing Ratio

  2.1 Concrete raw materials

  ① fly ash: Class I, high quality fly ash; ② cement: silicate cement, ordinary silicate cement; ③ additives: PCA, polycarboxylic acid high-performance water reducing agent; ④ sand and gravel: high quality river sand, fineness modulus less than 2.8, continuous particle gradation of gravel, particle size of 5 mm to 25 mm.

  2.2 Concrete ratio

  Use the best ratio of high-strength concrete to ensure the strength of concrete, but also to ensure that the fluidity and stability of concrete to achieve the best, in the appropriate viscosity as much as possible to extend the time of the slump, not to destroy the ease of concrete, and thus control the loss of pumping. Specific concrete preparation requirements are as follows.

  (1) Cement: The requirement of cement should preferably be high in content, preferably around 50%, and low in content, controlled at around 25%.

  (2) Fly ash: The maximum amount of fly ash should be controlled by conducting comparison tests.

  (3) Sand and gravel: the relevant regulations require that the maximum aggregate particle size to pipe diameter ratio is not greater than 1:5, and the crushed stone content of coarse aggregate should be controlled, the project uses 5 to 25mm continuous graded gravel according to local conditions.

  (4) admixture: choose polycarboxylic acid system water reducing agent to ensure that the concrete has low cohesiveness under the condition of suitable slump.

  3 Super high-rise concrete pumping construction technology

  3.1 How to select and calculate the conveying pump

  According to the total construction height of the project and the height of the concrete to be pumped, the height pressure in the pumping project is calculated by the relevant formula for calculation. The pressure R suffered during the pumping of concrete mainly includes the following parts.
① the pressure loss due to the resistance of the concrete as it flows in the pipe.
② the local pressure loss of concrete in vertebrae and bends.
(iii) The gravitational pressure on the concrete when it is pumped vertically.

  (1) the pressure generated by the internal flow resistance.

  Where: △ denotes the pressure loss per unit length along the course; represents the total length of the pipe, denotes the adhesion coefficient, denotes the velocity coefficient, denotes the diameter of the pipe conveying concrete, denotes the ratio of the switching time of the distribution valve of the concrete pump and the time of the piston pushing the concrete; denotes the flow rate of the concrete; denotes the ratio of the radial pressure to the axial pressure.

  (2) Local pressure loss in the vertebral and bent pipe parts.

  Three 90-degree bends each have 0.1 pressure loss; three 45-degree bends each have 0.05 pressure loss; according to the maximum and the longest horizontal pipe to calculate, bends a total of five, with the pressure loss of the valve is 0.2, each pipe set on the two matching valves. =3×0.05+3×0.1+2×0.2=0.85.

  (3) Gravitational pressure generated in the vertical section.

  The density of concrete is expressed by P, the acceleration of gravity is expressed by g, and the pumping height is expressed by H; =330×Pg.

  According to the calculation results, and combined with the construction schedule requirements of this project, the project finally decided to use the model HB40CH2135D and HBT90CH2122D trailer pumps respectively.

  3.2 How to arrange the conveying pipeline

  Because the part of setting the bend will increase the resistance of pumping, so when setting the conveying pipeline, the setting of bend should be reduced as much as possible. With the increase of pumping height, the vertical part will gradually increase, and the place of vertical pipeline is more prone to concrete backflow, so the place where the vertical pipeline increases should be set on the corresponding horizontal pipeline, which is used to buffer the concrete backflow.

  3.3 Technical measures for the production of pumping pipes

  When making the ultra-high pressure pumping pipe, we should use the quenched pipe with certain thickness and the special high pressure pipe clamp, and the pipe connection should be connected by the male and female buckle tapered centering method, and the O-ring should be sealed. When making ordinary high-pressure pump pipes, the pipes with wall thickness less than 3.5 mm should be replaced. The manufacturer of the pump is responsible for providing the clips of tempered steel plate material used in the production of high-pressure pumping pipes, and the end O-ring is used as the sealing ring, which should have a certain pressure-bearing capacity and be easy to set and operate.

In the process of pumping concrete, if a fault is found somewhere, in order to prevent concrete backflow, to immediately close the hydraulic shut-off valve; after pumping concrete, also to close the corresponding hydraulic shut-off valve, and to temporarily close the pumping pipeline, so that the transport pipeline and concrete recycling device can be more convenient to connect. In the case that the pumping floor is increasing, the pipeline after pouring concrete will always leave a lot of concrete, and the higher the height, the more concrete will be left.

At this time we need concrete each time after the completion of the pouring, the pump will retain more concrete, need to use the water washing function of the ground pump to flush it, in addition to ensure that the water washing function can meet the height of the pumping requirements.   

3.4 Pouring of reinforced concrete column

  According to the construction requirements of this project and the construction plan that has been developed, the core cylinder part should be installed and constructed first, and then the steel structure of the outer cylinder floor slab should be installed.

When pouring the reinforced concrete column, because the installation of the concrete slab outside the cylinder is lower than the installation of the steel structure, which leads to the operation layer without the operating surface of the steel beam, the construction staff also lacks the corresponding construction operation area, so it is very difficult to pour the reinforced concrete column with the pump pipe, but if the tower crane is used for pouring, it will increase the time of transportation, and it is difficult to meet the efficiency requirements of the construction. There is also no way to meet the construction progress requirements.

In addition, the safety of the construction workers is difficult to guarantee when the wind is strong when the material is put in the tank at high altitude. The impact of the traditional pouring on the construction schedule and the safety of the workers prompted us to search for a more effective and safer pouring method.

After a series of research and discussion, we decided to remove the climbing device, add a steel structure platform, and modify the wall-mounted hydraulic climbing fabricator. This kind of fabricator is very flexible and convenient to operate. After each reinforced concrete column is poured, a tower crane is used to move it to another place where it needs to be poured.

The H-beam arrangement of this project is not static, he has some changes, so we turned the steel platform and steel beam connecting bolts into mobile type, which can effectively adjust the spacing of the steel beam.

  4 Concrete pumping blockage of the causes and preventive measures

  Many situations will lead to the phenomenon of pipe blockage when pumping super-high rise concrete, pipe blockage will cause waste of concrete and delay the progress of the project, so it is necessary to prevent the phenomenon of pipe blockage in advance. To prevent it, we must first figure out the cause of the plugging.

  The main reasons why the phenomenon of pipe plugging will occur are.
① the incorrect connection of the pipe, the joint of the pipe is not well sealed.
② the pumping speed is not appropriate, the pipeline is not cleaned, and the downtime is too long.
③ affected by the environment.
④The concrete has quality problems.

  In view of the above reasons, the measures to prevent pipe blocking are.
①To prepare a scientific piping layout plan; use special seals, and tighten the joints of the pipes; before pumping, you need to inject the right amount of mortar or water to keep the pump moist.
②Pumping speed should be slow at the beginning and gradually increased; cleaning once after pumping to prevent concrete left in the pipe; stopping the machine, it should be turned on every 5 to 10 minutes.
③According to the change of seasons, mix the concrete with warm water in winter, and mix the concrete with ice water in summer. ④ Reasonable control of concrete slump; choose suitable raw materials; choose reasonable additives and control the dosage.

  5 Conclusion

  To sum up, the development of super high-rise buildings has driven the development of pumping construction technology for super high-rise buildings, and as the height of the buildings continues to increase, the requirements for construction technology will be higher and higher. It is believed that with the continuous improvement of science and technology, the concrete pumping technology of China’s supertall buildings will also be more comprehensive development.

Construction technology of drained asphalt concrete pavement for building construction

Drainage asphalt concrete pavement construction materials

Road construction on material permeability requirements are relatively high, to be able to achieve the safety of the project use standards, asphalt and concrete materials mixed with the use of the stability of the structure and the final use of the effect are very obvious improvement, better drainage of the road surface water, so that it will not affect the final structural stability.

1、Fine aggregates

Raw materials used in the basalt, the diameter of the material is relatively small, can be better integrated with cement and other raw materials, to ensure that the use of materials during the better with other raw materials with each other, together to enhance the stability of the use of materials.

Raw material selection to consider whether the weathering impact, the surface of the material if there is a dense weathering holes, will lead to the final use of lower standards, permeability increased at the same time the pavement structure strength will be significantly reduced. This feature should be considered during the test.

2、Coarse aggregate

The coarse material has stronger permeability, but the ratio added should be focused on control, and when collecting raw materials, consider whether they contain impurities, and if there are some other rock material debris, to clean up, so that the phenomenon of unreasonable use of raw materials can be avoided.

When the diameter of the rock material is relatively large, to ensure that the shape is similar to unity, take out part of the material, put it into the water and then observe the ability to absorb water, through this method can accurately determine the density of the material and surface weathering.

3、Asphalt

Asphalt in the high-temperature state will enhance the fluidity, the melting point of the material is judged by test analysis, pavement materials after a period of time, if the surface tension is not enough will lead to the emergence of structural cracks, extensive damage to the pavement.

The choice of asphalt materials with stronger viscosity can avoid such problems, and the construction efficiency will also be significantly increased, and can be integrated together with other rock materials. The mixed material obtained will be a great improvement in both waterproof performance and use standards.

4、Mineral powder

As one of the important materials for pavement construction, it accounts for only 4%. After using it, it can be the structure of the constructed project is more delicate, and the quality is improved after putting it into use, and it is not easy to appear cracks and other damage phenomena. Mineral powder is added to the concrete material, and the permeability of the test part is observed to reach the required standard. The drainage efficiency will also be significantly improved after the project is put into use.

Drainage asphalt concrete pavement construction materials with the design

Program design also has a very serious impact on the quality of the use of road projects, and it is very helpful to strengthen the cooperation between the design and construction program to optimize the drainage performance of the pavement. The design phase can be carried out with reference to the engineering file when considering the materials chosen, fully drawing on experience.

1、Target fit ratio design

Cooperate with the implementation of the construction target, to strengthen the regulatory control of the program. In the target mix ratio, the void ratio, aggregate ratio and asphalt amount belong to the main factors in the mix ratio, pavement construction through the measurement of the actual parameters to ensure that the target mix meets the needs of the actual construction technology, because China lacks effective experience in pavement construction technology, so only through the actual measurement to avoid omissions or mistakes in the design of the target mix ratio.

2、Production ratio design

The design of the production mix ratio is based on the target mix ratio, taking the measurement result of the target mix ratio as the reference result, firstly, the screen is set to ensure that the screen holes are effectively controlled, then the actual mix of production is realized according to the matching ratio of various types of hot materials in the target mix ratio, and finally the relevant standards are used to test the parameters, performance and technical indexes of the mix required for pavement construction.

3、Production ratio verification


The verification of the production ratio is based on the production ratio, firstly, the asphalt mixture is mixed according to the ratio derived from the production ratio, the test section is paved, and various tests are conducted, and finally the standard ratio for production is determined.

Construction technology of drainage asphalt concrete pavement

Drainage asphalt concrete pavement construction technology mainly contains three technologies, which are analyzed to ensure the sustainability of pavement construction.

1、Mixing technology

Mixing technology is mainly affected by the equipment, cycle and modifier. Mixing equipment mainly uses mixing machine, mainly intermittent, in order to prevent the pollution of the surrounding environment to be equipped with dust removal equipment, and at the same time do a good job of mixing and control work, pavement construction in the mixing frequency is high, in order to protect with the moisture content of the aggregate, the humidity must be controlled, first of all, with the humidity difference between the aggregate concentration adjustment, and after the humidity is appropriate

In the same time with other aggregates stored, mixing cycle can be set according to the actual situation of road The mixing cycle can be set according to the actual situation of the pavement construction, the basic project mixing cycle is: dry mixing 9s, wet mixing 44s, up and down to keep within the range of 2s set, the actual mixing of the mixture can be set in accordance with the specific conditions of the aggregate, the current pavement engineering modifier is mainly manually put, the same according to the actual situation to determine the mixing, no specific mixing standards.

Mixing the heating temperature of asphalt, the heating temperature of the aggregate, the factory temperature of the mixture and the temperature of the mixture transported to the construction site are to meet the standard requirements.

2、Transportation of the mixture

The type, number and tonnage of transport vehicles should be considered according to the daily production capacity of the mixing station and the distance from the mixing station. Transport vehicles should be cleaned in a timely manner, to keep clean, in order to prevent asphalt oil sticking to the box, the bottom and side of the box should be coated with a thin layer of oil and water, the ratio of oil to water is 3:1, in order to prevent asphalt pollution of the surrounding environment, and by the rain and temperature drop fast, transport vehicles should be covered with a shed cloth.

3、Paving technology

The use of paving technology is mainly to ensure the integrity of materials in pavement construction, paver rammer in construction, under the action of vibration, resulting in the destruction of raw materials, so the use of paving technology to adjust the rammer.

The rammer is divided into the main and vice two, when the main amplitude is taken 5mm, vice amplitude is taken 6mm, belong to the combination of the minimum destructive force on the raw materials, while the paver needs to be reasonably adjusted according to the pavement construction environment before using the paver, for example: adjust the paver fabricator, material level, keep the fabricator inside the mixture to be higher than the rotating material, about 2/3 of the position, while timely measurement of paving temperature, to ensure that the temperature is appropriate, will not Excessive impact on the construction with the material.

In the paving technology, the main thing is to ensure the rigor of the construction personnel, into the enclosure for paving compaction work before the construction personnel must keep a distance from the road, to avoid trampling events, affecting the efficiency of paving compaction, resulting in uneven pavement and poor drainage.

4、Grinding technology

Rolling technology in construction needs to have process, in the drainage asphalt concrete pavement construction, take the rubber wheel roller and two-wheel big vibration roller rolling can be (not special circumstances generally close vibration), because the road construction gap is relatively large, easy to cause temperature drop, therefore, the frequency of rolling repeated need to focus on improving, basically in the ordinary rolling about 2 times, can be appropriate according to the basic situation of pavement rolling The implementation of vibration, to ensure that the details of the rolling.

Rolling is divided into three processes: the initial pressure, recompacting and final pressure, and the temperature should be strictly controlled in each rolling process.

5、The treatment of joints

Whether it is a longitudinal joint or a transverse joint, it should be handled strictly, otherwise it will cause quality problems and leave safety hazards. For longitudinal joints, in general, hot joints should be used, and if the conditions do not allow it, when hot joints cannot be used, the joints should be cut according to the specification requirements.

For the horizontal joints, mainly to control the flatness, if not meet the requirements, and the longitudinal joints take the same method, according to the standard requirements for cutting joints.

Conclusion

With the rapid development of highway engineering construction, drainage asphalt concrete pavement in China has been fully promoted, and its construction process, whether in the selection of raw materials or in the ratio and construction process, there are strict requirements, therefore, it is necessary to protect the construction technology of drainage asphalt concrete pavement, both to improve the drainage effect of asphalt concrete pavement, but also to ensure the continuous drainage of asphalt pavement development.

A brief discussion on the maintenance management of concrete hydraulic buildings

1.Overview of diseases of concrete hydraulic buildings

The frequent diseases of concrete hydraulic buildings include cracks, freezing up, wear and weathering, rust and corrosion, etc. Different diseases have their performance characteristics.

Concrete cracks. In water conservancy projects will be barrage dams, bridge sections, gates, culverts and other concrete construction, these concrete buildings are prone to cracks, so that the building because of cracks and began to leak and freeze-thaw, a serious threat to the safety performance of water conservancy engineering buildings. Cracks are especially serious in the barrage dam body, gate bottom plate and retaining wall, etc.

Freeze-thaw damage. When the soil is in a water-filled state, the alternating effect of the forgiving and thawing cycle, in the cold climate, so that the soil and water contact and lead to freeze-thaw damage to the building. Usually, in the “three norths” area often occur in the concrete hydraulic buildings of freezing and thawing, and the damage of the concrete in the freezing and thawing cycle will occur freezing and cracking and surface spalling phenomenon, resulting in the elastic modulus of the concrete, strength and other mechanical properties reduced, thus endangering the safety of the building structure.

Wear and weathering. In the cold region of the river, dams and other water conservancy buildings, will often be subject to the collision of ice, or by the long-term wash of water, in such a collision, wash and other external forces for a long time, so that the water conservancy building long-term contact with the water part of the spalling, resulting in the concrete structure of the reinforcement exposed or concrete grinding into the honeycomb, reducing the life of the concrete structure, most concrete dams, gates Most concrete dams, locks, side piers, etc., the life of only l0 years, part of the tube can only be 5 to 6 years to maintain the repair.

Erosion, rust and corrosion. Once the cracks in the concrete structures of water conservancy projects, in the water and air wetting, so that the internal reinforcement of the concrete rust condition, coupled with industrial drainage in the water body will aggravate the erosion of concrete buildings, resulting in safety accidents of hydraulic buildings.

2.Concrete disease analysis

First, physical analysis. Concrete hydraulic structures in the long-term by external forces such as ice floating collision, mud flow abrasion, water impact scouring, etc., will make the concrete table spalling phenomenon, manifested as aggregate off, the formation of concrete surface cavities. Secondly, under the action of load external force, in the process of long-term temperature constantly changing, make the concrete building produce cracks, sink, fracture and other deformation.

Secondly, chemical analysis. For the concrete building of water conservancy project itself, three kinds of erosion phenomena will be produced.

① dissolution erosion, in the production of soil mix, its raw material calcium hydroxide contained in silicate cement has a large solubility, when in the flow of water, will make the calcium hydroxide in the soil mix slowly dissolve, and then reduce the concentration of lime in the soil mix, and the hydrated calcium silicate and hydrated calcium aluminate in the soil mix must be in a certain concentration of calcium hydroxide solution to maintain stable performance, once the calcium hydroxide decreases and disappears, it makes the hydrated calcium silicate and hydrated calcium aluminate start to decompose, which reduces the strength of the mix and cement mortar, and further destroys the mix structure under the invasion of external erosion medium.

② ion exchange erosion, the acid in the cement mix is in water for a long time, it occurs ionization, which makes it produce hydroxide ion exchange reaction to generate water and salt. Salt is easily carried away by water, which increases the voids within the concrete, reducing the strength of the mix, and the body of water then intensifies the erosion of the mix; in addition, non-soluble substances are produced during the chemical exchange reaction, which also does not cause volume expansion, but will soften the cement paste, and also increases the voids within the mix, increasing the penetration of water into the mix. In the water body inside, the cement soil will also occur in another chemical reaction, that is, ionization of magnesium ions, which then ionized with cement stone, producing a very small solubility of hydroxide ions, accelerate the decomposition of cement stone, and magnesium hydroxide itself is soft, no cementing properties, will soften the cement paste

③ sulfate erosion, the sulfate in the mix will react with the hydration products in the cement to produce calcium alumina and gypsum, after the wetting began to swell, the internal stress of the mix to destroy, if encounter and then meet sulfate and magnesium ions, but also to accelerate the destructive effect, because magnesium sulfate and hydrated calcium aluminate reaction to produce gypsum, aluminum glue, magnesium hydroxide, they all carry great destructive. In the concrete mix with voids, its reinforcement will produce rust, which is also damage to the concrete another factor.

3.Maintenance management of concrete hydraulic buildings

Take the concrete to construct the building, which is the mix itself has a good dense, seepage resistance, frost resistance and other properties, its strength is high, very durable. If the production of concrete mix is designed and experimented in advance, it can produce excellent performance of concrete mix, which can effectively prevent the aging of concrete mix and prolong the life of concrete structures. Strengthening the maintenance and management of concrete mix structures can be done by a combination of prevention and treatment.

Disease prevention.

First of all, we should strictly select the raw materials for making concrete mixes, and the best choice of cement is silicate cement, and ensure that all kinds of raw materials for concrete mixes meet the relevant standards and requirements.

Secondly, before making the mix, the best ratio of raw materials should be studied, and the test of strength and other properties should be passed before making a lot of mixes.

Finally, in the construction process, the construction plan should be selected scientifically and reasonably to ensure that the concrete construction can meet the relevant requirements, which can improve the quality of the concrete construction. In the specific construction process, it is necessary to do a good job of construction technology management and construction quality supervision, and timely check the construction quality against the design requirements to achieve standardized construction, which can effectively ensure the quality of the concrete mixing project.

For the anti-freezing performance of concrete, you can make the concrete mix, moderately reduce the amount of water and water-cement ratio, so that the concrete mix construction moisture, reduce free water, which can effectively reduce the chemical reaction about the destructive, reduce the free water brought about by the destruction of the structural void of the concrete mix. Appropriate addition of aerator, which produces micro-fine bubbles can block the water penetration channel in the mix. In addition, the bubbles have deformation function, which can effectively alleviate the freeze-thaw expansion. During the construction, it is necessary to flatten and vibrate the concrete mix evenly and densely to strengthen the performance of the mix.

Disease management.

Once the surface of the concrete structure is damaged, repair measures should be taken immediately. Usually, practical repair mortars include cement mortar and pre-shrunk mortar, while the repair methods include slurry spray repair method and vacuum operation repair method.

In the event of cracks, it is necessary to take the groove chiseling inlay method and the spray slurry repair method to coat the concrete table and then sticky patch. And the cracks need to be filled by grouting inside, and there are two kinds of grouting, cement and chemical. For crack leakage, it is necessary to analyze the cause of cracks, the degree of affected and the amount of leakage and its dispersion and concentration, and then choose to take buried pipe or borehole infiltration method to repair, and can also take filling method to repair. Culvert (pipe) crack leakage, need to paste epoxy adhesive in rubber, and then grouting, reinforcement of culvert foundation or structural reinforcement. Scattered seepage type concentrated seepage phenomenon should choose grouting measures and combine with surface coating and repairing impermeable layer to carry out comprehensive treatment. For water-stop structural joints leakage, asphalt patching method, chemical grouting method or building water-stop facilities again are needed to deal with it.

4.Conclusion

For concrete hydraulic buildings in the beginning of construction to the use of the period, will involve a variety of construction and management and maintenance work, and maintenance costs are relatively high, the worse the use of time, the higher the repair and reinforcement costs required, must strengthen the preliminary construction design and construction management, control the quality of concrete construction, can effectively reduce the repair and reinforcement costs later. In addition, it is also necessary to regularly and timely inspection and management of hydraulic buildings, in order to timely maintenance for the relevant problems.
