The welding quality of the composite geomembrane directly affects the anti-seepage characteristics of the composite geomembrane, so the construction of the geomembrane welding is very important. In this project, the welding of composite geomembrane is usually carried out on the spot by the manufacturer sending professional construction technicians.

In order to achieve the dual purpose of obtaining materials on site and dredging the river, graded natural gravel is used as the filling material. However, under the high water level of the river, the embankment filled with gradual natural gravel will seep obviously, causing the embankment or quicksand pipeline to collapse. occur. In order to solve the above problems, composite geomembrane is placed on the front and bottom of the dam.

According to the experience and lessons of the relevant engineering projects, in the real anti-seepage process, the peripheral access of the composite geomembrane usually becomes the most vulnerable or the weakest point where problems occur.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

Composite geomembrane is a new type of engineering waterproof material.

The polyethylene geomembrane has the dual functions of waterproofing and preventing plant roots from penetrating. It can withstand the puncture of plant roots and maintain the waterproof function for a long time. It can form a high-strength waterproof layer, has strong resistance to pressurized water, and is resistant to puncture, cracking, tearing, and fatigue.
