　　HDPE geomembrane is one of the geosynthetic materials, which can be used in anti-seepage projects such as sewage treatment plants, artificial lakes, domestic waste landfill sites, and solid waste landfill treatment. Next, let's talk about the preparation work that needs to be done when using HDPE geomembrane welding equipment for construction: start the generator and connect the power cord. Connect the geomembrane welding machine to the power supply and set the appropriate temperature for the welding machine. Plug in the power supply to the extrusion plastic welding machine and set the suitable temperature for the welding machine. When the temperature of the welding equipment reaches the set temperature, wait for 3 minutes before conducting the trial welding. Perform trial welding on the geomembrane welding machine, take the same strip, and weld it after adjusting the pressure, temperature, and speed. Peel and shear tests are conducted on the welded sample. When the base material is torn and damaged but the weld seam is not torn, the test welding is considered qualified. During the trial welding process, the welding machine equipment adjusts the temperature, speed, and pressure for formal welding. Because the slope is relatively large, a soft ladder should be hung on the slope, and construction personnel should wear safety belts and fasten ropes.

　　In the construction of tunnel waterproofing engineering, the primary attention is to control the quality of the suspension of waterproof boards. The current tunnel adopts the spray anchor construction method based on the New Austrian Method principle. After excavation, concrete is sprayed first for initial support as the primary lining, followed by the laying of waterproof boards and the construction of secondary lining. The laying of waterproof boards is carried out by using nail guns to drive cement nails to suspend the waterproof boards. In the initial stage, the sprayed concrete is relatively thin and the spraying thickness is uneven. When encountering areas with thin spraying thickness, it is difficult to drive the cement nails in, which can easily rebound and injure people, especially the nail caps. The exposed parts of the cement nails are sharp and can easily puncture the waterproof boards, causing them to fail. Therefore, it is necessary to pay close attention to the monitoring of the construction process during the suspension of waterproof boards. In addition, sufficient attention must be paid to the welding quality control of waterproof boards. In the past, waterproofing boards were generally welded using hot air blowers and soldering irons, making it difficult to ensure welding quality. Although double welds were used, it was still difficult to ensure that the welds did not leak. The climbing welding machine currently used can automatically form double welds, ensuring welding quality from a process perspective. According to the current sampling inspection results of tunnel construction, all welds welded with climbing welding machines can generally meet the inspection requirements in the inflation test, indicating that the quality of waterproof boards welded with climbing welding machines is relatively stable and the effect is good.
