　　Welding of anti-seepage membrane: 1. The welding process of the hot wedge welding machine is divided into: adjusting the pressure, setting the temperature, setting the speed, checking the overlap of the weld seam, installing the membrane, starting the motor, and applying pressure for welding. 2. There should be no oil stains or dust at the joints, and the overlapping section of HDPE anti-seepage film should not contain mud or other debris. If there are any debris, they must be cleaned before welding. 3. At the beginning of each welding day, a 0.9mm × 0.3mm sample must be tested and welded on site, with a lap width of not less than 10cm, and a tensile machine must be used for peeling and shearing tests on site. After the sample is qualified, it can be welded at the appropriate speed, pressure, and temperature at that time. The date, time, and temperature should be indicated on the sample. During welding, it is necessary to pay attention to the operation of the hot wedge welding machine at all times and adjust the speed and temperature according to the actual situation on site. 4.
