Recently, many friends have consulted the relevant content of the foundation grouting reinforcement and reinforcement construction technology, and the following is a summary of the relevant knowledge points, I hope it will help you.
Foundation grouting reinforcement is a common civil engineering reinforcement technology, which is mainly suitable for foundation subsidence, soft foundation, soil structure damage and other problems. This technology achieves the effect of reinforcement by injecting specific materials to increase the strength and stability of the foundation soil.
Material Selection:
1. Cement-based grouting materials: mainly using cement, mortar and other materials, by mixing with water to form a homogeneous mud, solidified in the foundation soil to form a hardened body, so as to strengthen the foundation. The cement-based grouting material has good durability and stability, and is suitable for various foundation reinforcement projects.
2.Resin-based grouting materials: Mainly using polyurethane, epoxy resin and other materials, by mixing with catalysts to form a solidified body, with high strength and adhesive performance. Resin-based grouting materials are suitable for the reinforcement of thin foundations and the repair of local small damage sites.
Performance: 1. Increased strength: After grouting reinforcement, the solidified body of the grouting material in the foundation soil forms a solid supporting structure, which can increase the strength and rigidity of the foundation and improve the bearing capacity.
2.Improved stability: The grouting material can fill and solidify the cracks and pores in the foundation soil, effectively prevent the deformation and settlement of the soil, and improve the stability of the foundation.
3.Improvement of compactness: In the process of grouting process, the grouting material can fully fill the voids in the soil, improve the compactness of the soil, reduce the permeability of the soil, and improve the engineering properties of the foundation.
Scope of application: 1. Foundation subsidence: Foundation grouting reinforcement technology is suitable for foundation subsidence repair, filling the void through grouting materials, improving the bearing capacity of the soil, and restoring the level of the foundation.
2.Soft foundation: For the problem of building sinking or tilting caused by soft foundation, grouting reinforcement can improve the bearing capacity of the building by increasing the strength and stability of the foundation soil.
3.Soil structure failure: For soil structure failure, such as soil collapse, cracks, etc., grouting reinforcement can fill the cavities and cracks in the soil, supplement the supporting capacity of the soil, and improve the overall stability of the structure.
Foundation grouting reinforcement technology plays an important role in solving foundation problems and civil engineering reinforcement, through the reasonable selection of grouting materials and construction methods, the strength and stability of the foundation can be improved, and the safety and reliability of civil engineering can be realized.
