HDPE Geomembrane is suitable for various environmental soils, and it is mainly used for anti-seepage and isolation engineering. The slope surface treatment should be carried out before the geomembrane is laid. HDPE geomembrane dam protection greatly improves the bearing capacity of the foundation, achieves a higher bearing capacity under the load, a better compaction state, and improves the stability of the foundation, which can effectively protect the dam. It can also better meet the requirements of water conservancy, transportation, and subway tunnel dam anti-seepage projects.
The performance characteristics of HDPE geomembrane dam protection:
1. HDPE geomembrane is a kind of flexible waterproof material with high tensile strength. It can resist the corrosion of strong acid, alkali and oil. It is a good anti-corrosion material, so that it has high tensile strength and can meet high standard engineering projects. need.
2. The overall performance of the tensile strength and elongation at break, use while maintaining the original performance, used in a variety of different harsh geological and climatic conditions. The use of high-quality virgin plastics and carbon black particles do not contain any preservatives, adapting to uneven geological settlement and strong strain.
3. The best real-time leveling after spreading is to construct the protective layer while laying the film. HDPE anti-seepage is not the same as the use of boundary lines to create different thickness and density. Expansion bolts and steel plate battens should be used for anchoring.
4. Temperature stress is generated in the HDPE geomembrane. When the landfill height is low, use the corrected temperature stress evaluation procedure to calculate. The temperature change is the primary cause of stress on the impermeable membrane.
