Abstract

The invention discloses a water collection and drainage device for deep foundation pits in building construction, and relates to the technical field of building construction. The water collection anddrainage device comprises a dewatering well, and drainage equipment fixedly installed in the dewatering well, wherein the dewatering well comprises downhole pipes which are provided with a number of uphole pipes connected in sequence, and the uphole pipes and the downhole pipes are connected; the uphole pipes comprise a pipe body, the bottom end of the pipe body is provided with an inner sleeve, the top of the pipe body is provided with a second guide tube, the end of the second guide tube is provided with a second nozzle portion, and there are two ends of the second nozzle portion; the top inner side wall of the pipe body is provided with a fixed convex ring, the upper surface of the fixed convex ring is provided with a plurality of second elastic telescopic members, and the ends of the plurality of second elastic telescopic members are provided with supporting ring bodies. Through the detachable downhole pipes and downhole pipes, the water collection and drainage device provided by the invention can effectively prevent the well pipe from being easily damaged due to a large amount of exposure of the dewatering well; meanwhile, the downhole pipes and the downhole pipes are matchedby the guiding sleeve of the first guiding pipe and second guiding pipe, and the disassembly and installation operation is simple.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a water collection and drainage device for deep foundation pits in building construction. Background technique [0002] In urban subway construction, due to construction needs, deep foundation pits with a depth of about 20 meters or even more than 20 meters often appear in the excavation of foundation pits. In the process of deep foundation pit excavation, foundation pit precipitation is very critical. Existing deep foundation pit dewatering usually adopts dewatering wells for dewatering, which usually set some dewatering wells around the edge of the foundation pit outside the foundation pit, so that the depth of the dewatering wells is greater than the depth of the foundation pit, so as to dewater. However, this construction method is used in areas with rich groundwater resources or abundant precipitation, especially in the south, such as Guangzhou, where groundwa...
