Geomembrane

Overlapping work is very important for geomembrane

The main function of using composite geomembrane in water conservancy projects is to enhance the anti-seepage effect of the entire project. From this perspective, overlapping work is very important for geomembrane.

According to the actual performance of composite geomembrane, it is necessary to strictly control the welding process and try to operate in a high temperature and low humidity environment. Before placing the geomembrane, someone should check its integrity, deal with the wrinkles and cracks on the surface of the geomembrane in time, and thoroughly remove the debris on the surface.






In the construction of water conservancy projects, the geomembrane required for the construction of the project is transported to the construction site by dump trucks. The basic transportation volume of the truck is 20.0 tons. Transportation requires a top-down rolling method. During the laying process, the deformation of the geomembrane must be controlled, and the working principle of relaxation must be followed to avoid imbalance of forces acting on the geomembrane.

At the same time, in view of the severe weather conditions during laying, it is necessary to do a good job of protection in advance. There will be wind when placing the geomembrane of this project. The geomembrane itself is light and thin, and it is easy to be blown away by strong wind. To avoid such problems, it is recommended not to place a larger area before laying the protective layer. At the same time, the geomembrane in the dam slope area must have a certain anchoring length in advance and anchored in the surrounding concrete or masonry structure to achieve the desired stabilization effect.
