Introduction of Composite Geomembrane in Water Conservancy

Research on Composite Geomembrane in High Earth-rock Dams

Characteristics of Non-woven Geotextile

Non-woven geotextiles are formed by laying long or short fibers into a network through different equipment and processes, and then making different fibers interweave with each other through needling and other processes. The composite geomembrane, through mutual entanglement and fixation, makes the fabric standardized, making the fabric soft, full, solid and stiff. The composite geomembrane for highway anti-seepage can reach different thicknesses to meet the application requirements. Non-woven geotextiles have good fabric gaps and good adhesion. Because the fibers are soft, they have a certain tear resistance and good deformation adaptability, as well as good plane drainage ability. The soft and porous surface has a good friction coefficient, which can increase the adhesion ability of soil particles and prevent the loss of fine particles by blocking the passage of particulate matter and removing the excess water. The soft surface has good protection ability. Geotextiles have good mechanical strength, good elasticity and deformation ability, making them very suitable for expansive or contractive base surfaces. The composite geomembrane for aquaculture anti-seepage can effectively overcome the uneven settlement of the base surface.
