Abstract

The invention discloses a device for rapidly blocking a dewatering pipe well through drainage and decompression and a method of the device. The device comprises a non-fine concrete dewatering pipe and a casing pipe. A cover plate is arranged at the top of the casing pipe. A water stop wing ring is arranged on the outer wall of the casing pipe. Four anchor feet are evenly distributed at the bottom of the outer wall of the casing pipe. The top of the non-fine concrete dewatering pipe is connected with the bottom of the casing pipe in a sleeved manner. The device is characterized in that the casing pipe is a cylindrical steel pipe sleeve, a carrying plate is arranged on the inner wall of the casing pipe, two or three round holes are evenly formed in the center of the carrying plate, short internal thread pieces are welded to the round holes and are hollow steel pipes, and plugs are arranged at the tops of the short internal thread pieces. According to the method, the device is used for drainage, decompression and rapid blockage of the dewatering pipe well, and the method aims at solving the technical problems that 20 minutes to 30 minutes is spent in welding a steel carrying plate conventionally designed for blocking the dewatering pipe well and sand, and gravel backfill work in the well cannot be finished before the dewatering pipe well is blocked.

Description

technical field [0001] The invention relates to a device and a method for rapidly plugging a downcomer well through diversion and decompression. Background technique [0002] The design of foundation pit dewatering generally adopts "sand-free concrete pipe" tube well for dewatering, which generally requires the completion of the underground main structure or the topping of the main structure on the ground before the downwater tube well is sealed. It takes 20 to 30 minutes to complete the work required for the welding of the steel plate supporting plate for the plugging of the tube well, and it is impossible to complete the backfilling of the sand and gravel in the well before the plugging of the downfall tube well. Contents of the invention [0003] The present invention provides a device and method for quickly sealing downfall tube wells through drainage and decompression to solve the deficiencies of the prior art, and aims to solve the need for 20 to 30 minutes to comple...
