Geomembrane is a waterproof material made from polyethylene raw materials through a blow molding process. It has the functions of anti-leakage, anti-puncture and isolation.Used for anti-leakage paving in lotus root planting, aquaculture, reservoirs, artificial lakes, rivers, sewage pools and landfills.Construction method: The overlap width of the geomembrane is 10 cm, and hot melt welding is used for construction.
Characteristics of polyethylene (HDPE) geomembrane:
Geomembrane has the dual functions of waterproofing and preventing plant roots from penetrating. It can withstand plant root puncture and maintain waterproof function for a long time. It can form a high-strength waterproof layer with strong resistance to water pressure and is resistant to puncture, cracking, tearing and fatigue.It has high tensile strength, large thickness of modified asphalt coating, and strong adaptability to base layer shrinkage and cracking. Excellent high and low temperature resistance, suitable for both hot and cold areas. Hot melt construction, easy construction and reliable and durable hot joints.
In anti-seepage projects, geomembranes are important anti-seepage materials, and choosing good quality geomembranes is crucial for anti-seepage projects. Width is an important indicator of geomembranes, and a wider width can bring many benefits to anti-seepage projects.For projects with larger laying areas such as tailings dams or evaporated sugar, geomembrane materials with wider widths should be used.
In anti-seepage projects, the most likely place for leakage is at the welding point of geosynthetics. The wider the width of the geomembrane, the fewer welds will be produced during actual welding construction. The fewer welds, the less likely it is to leak, and the higher the safety factor for anti-seepage projects.
Moreover, the increase in the width of the geomembrane and the reduction in welds also bring two other favorable conditions to the anti-seepage project. One is that it can reduce the overlap loss during welding construction: compared with the 7-meter-wide geomembrane with an 8-meter width, the theoretical loss rate can be reduced by 14%,which is conducive to reducing the cost of the project.Another point is that due to the reduction of welds, the time and labor required for welding will also be reduced, thereby reducing the construction period of the anti-seepage project and the corresponding labor costs. This advantage is particularly evident in some large-scale anti-seepage projects with strict construction period requirements.
