Recently, many friends have consulted the relevant content of the technical guidance for the construction of the reservoir curtain grouting reinforcement, and the following is a summary of the relevant knowledge points, hoping to help you.
Technical Guidance for Reservoir Curtain Grouting and Reinforcement Construction is a manual for the construction of reservoir curtain grouting and reinforcement, which mainly introduces the relevant material selection, performance and scope of application of the construction technology. Let's take a closer look at these below.
Material selection: In the grouting and reinforcement construction of reservoir curtain, it is necessary to select suitable materials to complete the reinforcement work. The first is cement, especially some common Portland cement, such as silicate normal cement, Portland cement, etc. This is followed by concrete additives, which improve the durability and strength of concrete by adjusting its properties. It is also necessary to select suitable filler materials, such as sand, stone powder, etc., as well as additives to control the fluidity of materials, such as water reducers, tackifiers, etc.
Performance: The performance of the reservoir curtain grouting reinforcement construction materials plays an important role in the quality and durability of the project. The properties of cement determine the strength and durability of concrete, for example, Portland cement has excellent early strength properties and long-term strength. Concrete additives can improve the flow of concrete, reduce shrinkage deformation and increase crack resistance. The filler material needs to have a certain particle size distribution and uniformity to achieve a good filling effect. Additives that control the fluidity of the material can make the slurry have the appropriate fluidity and viscosity to ensure the smooth progress of construction.
Scope of application: Reservoir curtain grouting reinforcement construction technology is mainly applicable to the following situations:
1. There is a leakage problem in the reservoir dam body, which needs to be reinforced by grouting and grouting is required;
2.There are many cracks in the dam structure, which need to be filled and reinforced.
3.The strength of the reservoir dam is insufficient, and the overall stability of the dam needs to be improved.
4.There is a gap between the dam and the foundation, which needs to be filled and reinforced.
Technical Guidance for Reservoir Curtain Grouting and Reinforcement Construction provides detailed guidance for the construction of reservoir curtain grouting reinforcement by introducing the selection, performance and scope of application of materials, so that the construction project can achieve the expected results and ensure the safety and stability of the reservoir.
