Embodiment
[0081] This embodiment provides a method for constructing a water-cutting curtain for a vertical concealed laying device of a magnetic-suction anti-seepage membrane, including the following steps:
[0082] Step 1: In the laboratory simulation, excavate section 1 along the axis of the curtain with double-wheel milling or hydraulic grab, with a width of 600mm and a depth of 1m. within the curtain line;
[0083] Mud retaining wall to keep the trough upright and stable;
[0084] Step 2: Flatten the anti-seepage membrane that meets the design requirements in length, width and thickness in the site;
[0085] Step 3, apply adhesive evenly on both ends of the unfolded anti-seepage film, and paste the magnetic soft film on the anti-seepage film coated with adhesive;
[0086] Step 4. The motor drives the driving wheel to rotate. The driving wheel drives the driving wheel to rotate through the power connection chain. The driving wheel follows the driving wheel to rotate, and drives the...

Abstract
The invention discloses a vertical hidden laying device for a magnetic impermeable membrane and a construction method of a water stop curtain, the vertical hidden laying device comprises a hollow base, the longitudinal front end and the longitudinal rear end of the hollow base are respectively provided with a membrane rolling structure support frame and a laying structure support frame, the membrane rolling structure support frame is fixedly provided with a membrane rolling structure, and the laying structure support frame is fixedly provided with a laying structure. A power structure and a power transmission structure are arranged below the film rolling structure; a film inserting structure is fixedly mounted on the laying structure supporting frame; the magnetic soft films are arranged on the edges of the two sides of the anti-seepage film, so that every two adjacent anti-seepage films provided with the magnetic soft films can be well and tightly bonded together within a small distance, high-strength magnetic attraction between the adjacent anti-seepage films is achieved, organic connection between the adjacent anti-seepage films is achieved, and the anti-seepage effect is good. The water interception property and the impermeability of the lap joint of the adjacent impermeable membranes are effectively improved, and the technical problem that in the prior art, the impermeability effect of the lap joint section of the adjacent impermeable membranes is poor is solved.
Description
technical field [0001] The invention belongs to the field of water-cutting curtains in coal mines and non-coal mines, and relates to the laying of anti-seepage membranes, in particular to a vertical concealed laying device for magnetically-absorbed anti-seepage membranes and a method for constructing water-cutting curtains. Background technique [0002] There are many types and quantities of mines in my country, and there are a lot of large water mines. Pumping wells or underground water holes are often used to control or reduce the mine water level. The daily drainage volume is tens of thousands of m 3 , even hundreds of thousands of m 3 , the drainage volume is huge. Long-term dredging has caused a large area of groundwater level drop, difficulties in domestic and production water use, shallow vegetation death, land desertification, drainage of mine water to pollute surface water bodies, huge cost of long-term dredging, and high production costs. [0003] Using water i...
