[0039] After the lower membrane steel plate 6 is clamped with the anti-seepage membrane main body 3, the auxiliary steel pipe 8 for blanking is tightened inside the nut seat 7. At this time, the winch main body 4 is continued to lower the steel wire rope 5, and the steel wire rope 5, the lower membrane steel plate 6 and the anti-seepage membrane main body 3 are moved toward the inside of the anti-seepage wall construction ditch as a whole. During the movement of the lower membrane steel plate 6 and the anti-seepage membrane main body 3, multiple groups of auxiliary steel pipes 8 for blanking are continuously spliced, and the auxiliary steel pipe 8 can be used to assist in pressing the lower membrane steel plate 6 and the anti-seepage membrane main body 3 downward to ensure that the anti-seepage membrane main body 3 is guided and positioned during the installation process. Ensure that the lower membrane steel plate 6 is level and avoids tilting. The lower membrane steel plate 6 can be steadily lowered and fixed to the bottom of the anti-seepage wall construction ditch slot hole, and it is also convenient for subsequent auxiliary work to lift the lower membrane steel plate 6;
