Problems solved by technology

[0002] The existing dewatering wells need to be waterproofed and sealed during construction. During the sealing, the downwater pipes are used to pump out the water inside the dewatering wells and then quickly seal them. However, groundwater will continue to gushes out during the sealing process. When sealing the dewatering well, the sealing material is easily washed by groundwater, resulting in poor sealing performance and potential water seepage

Embodiment 1

[0037] see Figure 1 to Figure 4 As shown, the present application provides a dewatering well self-sealing device, which includes a sealing plate 2, a sealing sheet 3 and an elastic device. A pipe hole 21 is provided in the middle of the blocking plate 2 . The blocking sheet 3 is movably arranged on the blocking plate 2 , and the blocking sheet 3 has a first state of blocking the passage hole 21 and a second state of opening the passage hole 21 . When the blocking sheet 3 is in the second state, the elastic device is in a stretched state, and when the blocking sheet 3 is in the first state, the elastic device is in an elastic reset state. When the self-sealing device for the dewatering well of the present application is used, the lower part of the dewatering well 1 is blocked by the sealing plate 2 and the outer periphery is sealed with the inner wall of the dewatering well 1. When the sealing plate 3 is in the first state, the sealing plate 2 and the sealing plate The sheet...

Embodiment 2

[0050] see Figure 1 to Figure 4 As shown, the present application provides a method for installing the dewatering well self-sealing device described in Embodiment 1, comprising steps:

[0051] S1, sealing and welding the sealing plate 2 and the inner wall of the dewatering well 1, the distance between the sealing plate 2 and the nozzle at the bottom of the dewatering well 1 is 0.5-1.5 meters;

[0052] S2. Adjust the blocking plate 2 to the second state, pass the downwater pipe 4 through the pipe hole 21 from the bottom nozzle of the downwater well 1, and extend to the outside of the top nozzle of the downwater well 1 to communicate with the pump.

Abstract

The invention discloses a dewatering well self-plugging device and a mounting method thereof. The dewatering well self-plugging device comprises a plugging plate, a plugging piece and an elastic device. A pipe passing hole is formed in the middle of the plug. The blocking piece is movably arranged on the blocking plate and has a first state for blocking the pipe passing hole and a second state for opening the pipe passing hole. When the plugging piece is in the second state, the elastic device is in a stretching state, and when the plugging piece is in the first state, the elastic device is in an elastic reset state. When the self-plugging device for the dewatering well is used, the plugging plate and the plugging piece automatically and completely plug the whole inner pipe opening of the well pipe body, a first water stopping measure is formed, and after water stored in the dewatering pipe is pumped, concrete pouring or other plugging measures are conducted on the interior of the dewatering pipe; and the blocking construction difficulty caused by too large underground water pressure can be effectively reduced, and the blocking quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of dewatering wells, in particular to a self-sealing device for dewatering wells and an installation method thereof. Background technique [0002] The existing dewatering wells need to be waterproofed and sealed during construction. During the sealing, the downwater pipes are used to pump out the water inside the dewatering wells and then quickly seal them. However, groundwater will continue to gushes out during the sealing process. When sealing the dewatering well, the sealing material is easily washed by groundwater, resulting in poor sealing performance and potential water seepage. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The invention provides a self-sealing device for a dewatering well and an installation method thereof, capable of automatic sealing and ensuring the sealing quality. [0005] The first object of the present invention is to provid...
