Abstract
Description
technical field
[0001] The invention relates to the technical field of underground seepage prevention and pollution control, such as open-pit coal mine water-cutting curtain, metal mine water-stopping curtain, underground mine anti-seepage curtain, pollutant isolation, municipal and industrial and civil construction water-cutting curtain, and especially relates to an anti-seepage A membrane joint self-adhesive device and a method for constructing a self-adhesive water-cutting curtain. 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 veget...
Examples
Embodiment 1
[0051] Step 1: Curtain wall groove section 1 adopts double-wheel milling or hydraulic grab to form grooves, with a width of 600mm and a depth of 50m. It is generally located in the water-resistant layer, and the foundation pit, pollutant diffusion area, open pit or underground mine trap are enclosed .
[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 until the depth reaches the design depth, and the top of the first anti-seepage membrane 2 can be fixed on the curtain wall with rivets Slot section 1 notch;
[0053] Step 3: Lower and lay the second anti-seepage membrane 3 close to the side of the curtain wall groove section 1 until the depth reaches the design depth. The second anti-seepage membrane 3 and the first anti-seepage membrane 2 overlap 2m laterally. The top of membrane 3 is fixed to the notch of curtain wall groove section 1 with rivets;
