　　Pre hanging welding of waterproof board:

　　Cut 2-3 rolls of narrow waterproof boards according to the planned area outside the hole, and then lay them flat on the ground and weld them together to form a large waterproof board that is easy to transport and hang, reducing the number of welds in the hole and improving the welding quality. Waterproof boards should have fewer joints.

　　The waterproof board splicing adopts double weld welding with a heat sealing machine, and the overlap width is required to be no less than 100mm. The temperature and speed of the heat sealing machine should be controlled to ensure the quality of the weld. The weld seam should be tight, and the effective welding width of a single weld seam should not be less than 12.5mm. Before welding, the surface of the joint to be welded should be wiped clean, and the welding temperature and speed should be determined through testing based on the material. During welding, it is necessary to avoid missed welding, virtual welding, burning or welding through.

　　The length of the one-time laying along the longitudinal direction of the tunnel should be about 1.0m longer than the length of the secondary lining construction, in order to connect with the waterproof layer of the next cycle; At the same time, the waterproof layer joint can be staggered with the lining concrete joint by about 1.0m, which is beneficial for preventing water leakage from the concrete construction joint.

　　Below is an introduction to the method of using a climbing welding machine for welding in composite geomembranes: When splicing composite geomembranes, climbing welding machines are often used to weld some joints. The welding method used is called hot melt welding, which generally requires a high temperature of 200 degrees Celsius. Then, the joints of the geomembrane are pressed together to ensure that the quality of the composite geomembrane meets the design requirements after welding. When using a climbing welding machine for construction, it is necessary to blow off the sand, gravel, and debris in the area to be welded to make the film surface relatively clean. Then adjust the width of the geomembrane that needs to be welded in advance. Generally, the overlap width during welding is eight to ten centimeters. Then use the welding pulley clamp in the mechanical equipment to clamp the composite geomembrane to be welded before turning on the climbing welding equipment. This way, the climbing welding can be automatically performed. And during welding, the lines are relatively straight and smooth. Generally, the walking speed needs to be controlled at 12 to 15 meters per minute. In order to ensure smooth construction, a dedicated person is needed to cooperate in controlling the wires and switches. During the construction process, the temperature of the climbing welding machine is very high, which inevitably causes the composite geomembrane to burn out. So there should be a dedicated person to repair the damaged parts, usually using strong glue to complete the repair. Mastering the correct method of climbing welding machine welding can ensure the quality of engineering construction.
