Embodiment 1

[0051] Step 1: The curtain wall groove section 1 is formed by double-wheel milling or hydraulic grabbing, with a width of 600mm and a depth of 50m. It is generally located in the water-retaining layer and encloses the foundation pit, pollutant diffusion area, open pit or underground mine. .

[0052] Step 2: After the curtain wall groove section 1 is formed, lower and lay the first anti-seepage membrane 2 close to the side of the curtain wall groove section 1, and the depth reaches the design depth. The top of the first anti-seepage membrane 2 can be fixed on the curtain wall with rivets. slot 1 slot;

[0053] Step 3: Lay down and lay the second anti-seepage membrane 3 close to the side of the groove section 1 of the curtain wall, and the depth reaches the design depth. The top of the membrane 3 is fixed to the notch of the curtain wall groove section 1 by rivets;

[0054] Step 4: Place the anti-seepage membrane joint self-bonding device on the overlapping section 4 of the fi...

Abstract

The invention relates to a self-adhesion device of an impermeable membrane joint and a self-adhesion type water interception curtain construction method thereof. The self-adhesion device comprises animpermeable membrane, a magnetizing rod or magnetizing plate, an anode cable, a cathode cable, a magnetizing and demagnetizing machine and the like, wherein the magnetizing and demagnetizing machine is connected with the magnetizing rod through the cathode cable and the anode cable, the magnetizing and demagnetizing machine enables a coil to generate a transient ultrastrong magnetic field throughinstantaneous pulse large current in the coil, magnetic materials in the coil can be permanently magnetized by the magnetic field, and the magnetizing rod or magnetizing plate is placed in the position of a to-be-activated impermeable membrane joint, so that the impermeable membrane joint is magnetized, the position of the impermeable membrane joint is activated as a cathode joint and an anode joint, and self adhesion of the impermeable membrane joint is realized. Thus, the problems that adjacent impermeable membranes are not firmly bonded, the lap joint is not tight and the impermeable effectis poor can be effectively solved, and the tightness and the impermeable performance of the lap joint of the impermeable membranes are improved while the problem that the vertical laying depth is limited is solved.

Description

technical field [0001] The invention relates to the technical fields of underground anti-seepage and pollution control such as water-cutting curtains for open-pit coal mines, metal mines water-stopping curtains, anti-seepage curtains for underground mines, pollutant isolation, municipal and industrial and civil construction water-cutting curtains, etc., in particular to an anti-seepage curtain A membrane joint self-adhesive device and a self-adhesive water-cutting curtain construction method thereof. Background technique [0002] Most of the open-pit coal mines in my country are located in the sand and pebble layer areas with strong water richness and strong recharge. The stratum has a large permeability coefficient and is recharged by surface rivers. Long-term dredging will cause a large area of ​​groundwater level drop, difficulties in living and production water for surrounding residents, the death of shallow vegetation, land desertification, mine water discharge to pollu...
