A non-pressure sealing wall for preventing and controlling high-pressure water inrush points

Abstract

The invention discloses a non-pressure sealing wall for prevention and control of a high pressure water inrush point. The non-pressure sealing wall comprises a grout stopping wall body and a water retaining wall body, a grouting pipe is arranged on the lower portion of the grout stopping wall body, and two sets of water drain pipes are arranged on the grout stopping wall body. The water drain pipes penetrate through the grout stopping wall body and the water retaining wall body, after penetrating, the two ends of the water drain pipes extend outside, and the grout stopping wall body and the water retaining wall body are divided into upper and lower parts through lifting slots. According to the non-pressure sealing wall for prevention and control of the high pressure water inrush point, a more efficient and more practical water inrush point non-pressure sealing wall is provided, the arbitrary discharge of the water flow of the sealing wall is limited by sealing roadways on the two sidesof the water inrush point by the sealing wall, no excessive water pressure is existent in the formation sealing through pipeline discharge, so that the sealing wall is prevented from cracking due tohigh pressure, and in cooperation with a pumping device, the production environment of coal mines is improved.

Description

technical field [0001] The invention discloses a mine water outlet sealing device, in particular to a pressureless sealing wall for preventing and controlling high-pressure water inrush points. Background technique [0002] Currently, the sealing structure of the high-pressure water inrush point on the underground floor of the coal mine mainly includes dynamic water drilling and hydrostatic high-pressure sealing of the sluice wall. The method of dynamic water drilling and grouting has a long construction period. The hole is difficult, and grouting is likely to cause secondary damage to the bottom plate; the method of hydrostatic high-pressure grouting for building the sluice wall has a short construction period and high cost. secondary damage. Contents of the invention [0003] The object of the present invention is to provide a non-pressure sealing wall for preventing and controlling high-pressure water inrush points, which has solved the problems raised in the above-men...
