What is the specific content of the discussion on dike construction technology of water conservancy projects? The following Zhong Da Consultation will answer your questions.

1 preface

Life on earth began to exist from water, and it is precisely because of water that human society can develop to this day. Therefore, no matter how human society develops in the future, we can't live without water. But it is also an important issue in the management of rivers, lakes and oceans. It is precisely because of the emergence and development of water conservancy engineering industry that disasters such as floods have been avoided and the safety of people's lives and property around them has been guaranteed. Due to the increase of population, economic development and the increase of buildings around rivers, lakes and oceans, the construction and reinforcement of dikes and their quality and safety have become more important. Of course, dike construction technology is developing better and better, and great progress has been made. In the following, several dike structure types and quality assurance measures are put forward, and some water conservancy engineering construction measures are put forward, hoping to make water conservancy dikes develop and innovate and promote the development of water conservancy engineering industry in the whole country.

2 the importance and role of dike construction in water conservancy projects

As the source of life, water is also the foundation of human life and world development. Without water, human beings can't live normally, even related to human survival. It can be converted into various energy sources to promote the development of the country. However, liquid water is mostly in the natural state, so there are many difficulties in converting it into other energy, and then many problems appear. In addition, improper management of it will also bring floods and affect people's safety and economic property. Therefore, water conservancy construction can solve these problems and use water resources conveniently and effectively. Therefore, water conservancy projects have also been highly valued. Water conservancy projects are mainly flood control, and flood control is inseparable from dike projects, so dike projects are more important. The main function of dikes is actually to store water. In fact, it has been widely used for a long time. Its functions can be summarized as preventing floods, storing energy and promoting social development. Because its function is very important, it also has strict requirements. For example, it can be well earthquake-proof and has strong anti-seepage ability. Its quality must pass, so as to better prevent leakage, ensure the stability of the dike and prevent potential safety hazards.

3 water conservancy dike construction technology

3. 1 construction technology of cutoff wall

Concrete cutoff wall technology is the most common cutoff wall construction technology. Because its use value and construction effect are very good, and the material it needs is concrete. Therefore, we should also pay attention to the quality of concrete on the premise of ensuring technology. There is something wrong with the quality of materials, and no matter how good the technology is, it can't guarantee the quality and safety of the whole project. This kind of concrete construction technology is just one of many technologies, it is a big name, and its construction methods are also many. The following are the more common ones:

3. 1. 1 plastic wall-forming technology

Plastic concrete can be said to be an indispensable part of concrete construction technology. This plastic concrete wall technology is briefly introduced. It is impossible to complete the construction task normally by oneself, and we must rely on the assistance of drilling technology. However, for the existing dike structure, we can use drilling technology to build accurate holes at suitable locations, and then pour plastic concrete according to the holes. This can achieve the firmness of the dike, but also has a certain degree of safety and stability.

3. 1.2 vibration wall-forming technology

In the construction of water conservancy projects, vibration wall-forming technology is also very common. For this technology, it can also achieve good implementation, and external factors can not affect this technology. For this technology, it is mainly its vibration frequency, so the correct vibration frequency can ensure its effectiveness and find the accurate design position. Only in this way can the concrete pouring work be more convenient, not easy to make mistakes, and can fully play its role.

3. 1.3 impact grooving technology

This technology is also a common method, mainly by impacting at an appropriate and accurate place to obtain holes; Then began to pour materials, which effectively increased the overall firmness and stability. This method is still very important in the construction of concrete cutoff wall, and its construction effect is very obvious.

3.2 Split grouting technology

Split grouting anti-seepage technology belongs to high pressure grouting consolidation anti-seepage technology. Due to high-pressure grouting, cracks appear in the soil layer of the dike, so slurry can be poured into the cracks, thus strengthening the cutoff wall and ensuring the seepage prevention performance of the whole dike. The concrete process is to adopt split grouting on the embankment, then arrange holes along the axis, and finally split the embankment soil layer and inject high-concentration slurry, thus forming a denser impervious layer. No matter where the dike is defective, the split grouting construction technology can be used to make up for the leakage and enhance the stability of the dike. In addition, the split grouting construction technology has many advantages. Generally speaking, her construction time is short, the speed is fast, and the difficulty is not great, and the requirements for construction materials are not high, which not only saves time and reduces the construction cost, but also prevents some potential safety hazards, so it is a very good technology for dike construction technology of water conservancy projects.

3.3 High-pressure injection technology

As can be seen from the name, high-pressure jet technology mainly uses high pressure, then injects slurry into embankment, and then forms an organic whole through stirring. When the slurry hardens, it plays a leak-proof function and increases its firmness. This technology also has some advantages. It does not need complicated equipment, but it has high construction efficiency and can be widely used.

3.4 Filling construction technology

Filling construction is the most important in the process of dike reinforcement. Before construction, it is required to clean the embankment foundation according to the design, including the sundries and garbage on it. Moreover, the scope of cleaning should be clear before construction, so it is not easy to make mistakes. For the cleaning step, it is necessary to find the cleaning line of the embankment surface. If it is a new embankment, it must be in strict accordance with the requirements of the design foundation surface. For the old dike, it is mainly to clean up the sundries on it. After cleaning, it needs to be compacted, and then the preparation work begins. In this process, the compactness of soil should be guaranteed as required, so as to ensure and improve the quality and effect of the project. The earth embankment is filled by reverse pushing method, which can improve the benefit. Pay attention to the thickness of each layer and control it well when discharging, generally 30cm is appropriate. When filling, water content is an important factor, so it should be strictly controlled to ensure the normal filling project. Too high or too low water content will affect the filling effect, but if this happens, some measures need to be taken to ensure the construction effect. When it is too high, you can take the method of drying; If it is low, it can be solved by sprinkling water properly. When the filling is completed, the next slope repair construction is needed. In the process of slope repair, attention should be paid to every detail to ensure the construction quality and avoid potential safety hazards. When every step is carefully done and strictly meets the requirements of the design scheme, not only the quality can be ensured, but also the effect is very good. Thereby being beneficial to improving the flood control construction effect of the dam. The dike body is the most important, and its quality is closely related to technology. Therefore, both technology and professional quality of personnel need high requirements.

3.5 Compaction technology

After paving, it needs to be compacted. Compaction is mainly to ensure the quality of the dike and the benefit of the whole project. There are two ways to pass the compaction degree of the project: layered paving and compaction, and the next rolling work can only be carried out after the layered paving and compaction are qualified. In the compaction work of the whole dike project, the rolling test must be carried out before the work and recorded accurately, so as to accurately control the loose laying thickness of each layer, the driving speed during the rolling process and other related indicators. In the general compaction process, the speed is usually 2 km/h, and it is rolled for 3 times. After completion, inspection must be carried out to find out the unqualified places and re-construct, so as to better ensure the construction quality and improve the degree of compaction.

4 embankment construction quality control and its safeguard measures

4. 1 Quality control of embankment foundation and bank slope

Dike foundation is an important part of water conservancy project, which plays a major supporting role and is also the foundation of dike. If we only observe it from the surface, we can't really see its function, let alone reflect its function. It is precisely because of this problem that if the test is not carried out, the problem can not be found only through the observation of the construction personnel, so it can not be corrected in time, which will lead to some safety accidents or hidden dangers. Therefore, in the process of dike construction, every link should be responsible for the construction as required, even if the problems in the construction process are solved, quality management should be done at the same time. Therefore, the management work in the construction process is particularly important, which plays a supervisory role, standardizes the operation, and combines the design requirements to ensure the qualified rate of each index. 4.2 Filling quality control In order to give full play to the role of dike engineering in resisting floods, it is necessary to require the dike to have strong compressive capacity. The construction quality of the whole project is accumulated bit by bit by the quality of each link, so if you want to have the quality of the whole project, you must control each link well. This work requires the joint efforts of construction personnel and management personnel. The first step is to ensure the cleanliness of the surface, and a certain cleanliness can ensure that its wettability is suitable enough. The second step is to strictly control the depth and density, followed by unloading and filling. For the supervision of soil quality, it is more necessary to meet the requirements of construction design. For filling, besides the material requirements and the cleanliness requirements of the filling part, there are also problems of speed and equipment design. Most people will think that these are trivial matters, but in fact, every link is crucial. The accuracy, standardization and safety factor of each link affect the quality and benefit of this project more or less. The filling speed, whether too fast or too slow, will affect the quality and efficiency of this filling process. For the equipment needed for construction, it is also necessary to check it regularly to avoid some data errors or delay the construction period.

4.3 Engineering Appearance Quality Control

For any building, including water conservancy dike project, the first thing that catches your eye is its appearance, so the appearance work is also a particularly important part, which involves the aesthetic feeling of the project, and reasonable modeling can also ensure the structural quality and stability of the whole dike. For example, some building overpasses have both aesthetic feeling and great utilization rate. Therefore, these problems should be considered in the design scheme before construction and attached great importance to in the construction process, so as to strengthen quality management and meet relevant standards. The appearance of the dike should first look neat, because it not only affects the aesthetic feeling, but also relates to the quality and stability of the water conservancy project. Therefore, in any case, we should pay attention to the construction problems, the appearance design work before construction, and pay off as planned, so that each link can meet the design standards.

4.4 Choose a good construction unit and attach importance to engineering test.

No matter how excellent the construction scheme is, how advanced the equipment is and how high-quality the management personnel are, the construction unit must complete the construction process. The construction unit is an indispensable part of the project construction, and it also affects the whole project. Therefore, for the selection of construction units, after the dike project is determined, the construction units can be screened by bidding, and the indexes of the construction units are comprehensively investigated, so as to select the most suitable and best cooperative construction unit, which can further ensure the smooth progress of the project and lay the foundation for improving the quality of the dike. Including soil sampling test, filling construction detection, compactness detection, etc., to fully grasp the quality of dike engineering and provide reference for engineering quality control and improving construction effect. Most people think it is good to finish this project. On the surface, it seems that the project has been completed, and they often ignore a test of the project. Not only is the test project not really completed. Engineering testing is still very important. Through inspection, we can find out the problems existing in that part of the whole project and the places that need improvement, so as to ensure the quality of the project, eliminate some potential safety hazards and promote the development of water conservancy projects.

4.5 Improve the organizational structure

It can be said that the organization manages the operation of the whole project or company, so it is necessary to improve the organization and add a complete and reasonable management system to increase the protection of the project. Every construction worker should do his duty and strictly follow the work requirements, and the organizer should do a good job in management and play a leading role, so as to mobilize the responsibility of the construction workers, effectively ensure the maximum utilization rate of various construction technologies and improve the engineering efficiency. A sound system is also an important part. As the saying goes, there is no Fiona Fang without rules. Therefore, both the progress of the project and the development of the company need a perfect system in order to better carry out construction and management and promote the development of water conservancy projects.

5 concluding remarks

To sum up, the correct application of construction technology is very important for modern water conservancy projects under construction. In the construction, we must accurately grasp the key points of each construction, treat each stage of water conservancy project seriously and strictly, and don't cut corners and build unqualified projects for personal benefit. Water conservancy projects can play a great role in flood disasters. If the dike is not built, when the disaster comes, the dike will lose its protection and the consequences will be unimaginable. Therefore, we should strengthen some regulations on dike construction management of water conservancy projects. In order to build a safe, stable and solid water conservancy project, we should also strengthen the daily maintenance of water conservancy projects and reduce the leakage caused by improper dikes, which can also extend the service life of the dam. From this point of view, dike construction is a very important content in water conservancy project construction. In order to improve the quality of the project, every link in the construction must be strictly checked. Although this will slow down the construction progress, the quality of the project is well guaranteed. In other words, our lives are well protected. It can also make water conservancy projects play a better role in daily operation. This has also laid a solid foundation for social stability and the improvement of people's living standards. In the process of construction, it is necessary to flexibly use construction technology and do a good job in preparation for construction to ensure that water conservancy projects can play their due value, which indirectly proves that China's economy is developing continuously. Only by doing a good job in dike construction can we successfully complete one solid and practical water conservancy project after another.
