The main function of using composite geomembrane in water-saving projects is to improve the anti-seepage effect of the entire project. From this perspective, the overlap of geomembrane is very important.
According to the actual performance of the composite geomembrane, the welding process should be strictly controlled, and the welding should be tried in a high temperature and low humidity environment. Before laying the geomembrane, a dedicated person should check its integrity, deal with the wrinkles and gaps on the surface of the geomembrane in time, and arrange to completely remove surface debris. In the construction of water-saving projects, the geomembrane required for the construction 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 principle of relaxation must be followed to control the deformation of the geomembrane and avoid the imbalance of forces acting on the geomembrane. At the same time, given the severe weather conditions during the laying period, adequate protection work must be carried out in advance. When laying the geomembrane for this project, the wind-blown geomembrane itself is thin and thin, and it is easy to be blown away by strong wind. To avoid such problems, it is recommended not to lay a large area before laying the protective layer. At the same time, the geomembrane in the slope area of the dam must have a fixed length in advance and be fixed on the concrete or surrounding masonry structure to achieve the ideal stabilization effect.
