Problems solved by technology

[0002] As we all know, the foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the buildings near the site, and waterproof and drainage should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope. The slope size is determined according to the relevant construction regulations. The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures adopted for the side wall and the surrounding environment; steel wire mesh is often used to isolate the soil in the existing foundation pit support, but usually a layer of steel wire mesh cannot isolate the soil well, so it needs to be laid Several layers, but the operation of laying layer by layer is too troublesome, and the existing support structure is too scattered to be installed in a centralized manner, resulting in slow installation speed of the support structure, and the existing support structure has poor water resistance , the supporting structure is not waterproofed
