Impermeable membrane connecting device for water interception curtain and water interception curtain construction method thereof

Abstract

The invention discloses an impermeable membrane connecting device for a water interception curtain and a water interception curtain construction method thereof. The device comprises a box body, a connecting male head, a connecting female head, supporting holes, a cavity and an air bag; the box body is a hollow rectangular cylinder; the middle of the box body is a hollow cavity; the connecting malehead is arranged on the upper portion of the box body; a through pin hole is formed in the center of the connecting male head; the lower portion of the box body is provided with the connecting femalehead; the connecting male head and the connecting female head of each section of the connecting device are fixed through pins and the pin holes; the multiple through supporting holes are formed in the box body at intervals; and the air bag is embedded in the hollow cavity of the box body. According to the impermeable membrane connecting device for the water interception curtain and the water interception curtain construction method thereof, the problems of poor connectivity, untight lap joint, streaming of a filling material, difficult pulling of a joint device and poor anti-seepage effect ofadjacent anti-seepage films can be effectively solved, organic connection between the anti-seepage films in each sequence is realized, backflow of slurry or concrete in a groove section is prevented,the pulling resistance of the connecting device is reduced, and the water interception efficiency of the impermeable membrane curtain is improved.

Description

technical field [0001] The invention relates to the technical field of underground anti-seepage and pollution control such as open-pit coal mine curtains, metal mine curtains, underground mine curtains, pollutant isolation, municipal and industrial and civil construction water-cutting curtains, and especially relates to an anti-seepage for water-cutting curtains Membrane connecting device and construction method thereof. Background technique [0002] Most of my country's open-pit coal mines are located in sandy pebble areas with strong water and strong recharge. The formation has a large permeability coefficient and is recharged by surface rivers. Pumping wells are often used to control or reduce the mine water level, and the amount of rainfall is huge. Long-term dredging has resulted in a large-scale drop in groundwater levels, difficulty in producing water for the surrounding residents, death of shallow vegetation, land desertification, discharge of mine water to pollute s...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an anti-seepage membrane connection device and construction method for water cut-off curtains, which can effectively solve the problems of poor connection of adjacent anti-seepage membranes, loose overlap, bypass flow of filling materials, and pull-out of joint devices. Difficult and poor anti-seepage effect, realize the organic connection between each sequence of anti-seepage membranes, prevent the backflow of grout or concrete in the groove section, reduce the pulling resistance of the connection device, and improve the water interception efficiency of the anti-seepage membrane curtain
