What Should I Pay Attention To When Using HDPE Anti-seepage Film In Winter?
HDPE anti-seepage film is widely used in various projects. Due to the material characteristics of anti-seepage film, the use of anti-seepage film in different seasons is also different. Let us explain the problems to be paid attention to when using HDPE anti-seepage film in winter.
The HDPE anti-seepage film is brittle in winter. In order to prevent the membrane from being broken due to the disturbance of the membrane in winter, water leakage should occur. Avoid laying HDPE anti-seepage membrane in winter and carry out dam that may cause membrane disturbance and brittle fracture. Construction. Secondly, it should be avoided that due to the large settlement of the dam, the settlement of the front dam slope during the winter operation period of the reservoir will cause the membrane to be brittle. Therefore, the dam body should be layered and crushed according to the design standard. After each layer is crushed, it should be immersed in water to ensure the filling of the dam body.
HDPE anti-seepage film needs to be spliced or connected with the peripheral toe board, and its quality directly affects the anti-seepage performance of the anti-seepage film. Before the HDPE impermeable membrane is laid, the construction of the underlying layer without sand concrete is carried out, and then the rolled geomembrane is laid vertically along the dam slope from the bottom to the top. The laying should be smooth and tight, leaving about 1.5%. Width to protect against damage. After the geomembrane is flattened, the self-propelled hot-melt double-stitch welder is used for splicing. According to the type, thickness and outdoor temperature of the membrane, the appropriate welding temperature and walking speed are selected. First, the small piece is used for trial splicing at the site. After the stabilization, the actual welding operation is performed.
The above notice about the use of HDPE anti-seepage film in winter is finished. I hope everyone should pay more attention when using HDPE anti-seepage film in winter. If you have any problems, please contact us. We have professional technicians to help you.
