Description

Building foundation pit drainage structure of infiltration prevention Technical Field The utility model relates to the technical field of foundation pit drainage, in particular to a water seepage prevention building foundation pit drainage structure. Background In the field of construction, foundation pit drainage is a vital link. During the excavation process of the foundation pit, a large amount of groundwater or surface water often infiltrates into the foundation pit due to high groundwater level or rainwater infiltration and the like. The existence of the water not only can influence the stability of the foundation pit, but also can cause safety accidents such as sliding and collapse of the wall body of the foundation pit, and the safety accidents can form serious threat to personnel and equipment on a construction site. In the traditional foundation pit drainage method, a drainage pump is used for directly pumping accumulated water in a foundation pit, or drainage ditches, water collection wells and the like are arranged to guide water to a low place for drainage. However, these methods often have problems such as low drainage efficiency, incomplete drainage, and easy blockage. Especially when encountering a large amount of seepage water or deep groundwater, the traditional method is difficult to deal with, so that the foundation pit drainage effect is poor, and the construction progress and the engineering quality are affected. In addition, the traditional foundation pit drainage structure has obvious defects in the aspect of water resistance. The wall body of the foundation pit often has water seepage channels due to reasons of materials, construction technology and the like, so that water seeps out from the wall body of the foundation pit to form a water seepage phenomenon. The water seepage not only can increase the drainage difficulty, but also can damage the stability of the foundation pit wall body, and the potential safety hazard is caused. In view of this, we propose a water seepage-proof construction foundation pit drainage structure.
