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...
