Geomembrane liner for canals and reservoirs

Geomembrane has the advantages of light weight, high strength, high elongation, good anti-seepage performance, strong adaptability, simple construction and low cost, so it is widely used in water conservancy projects.
Suizhong is located in the Western Liaoning Corridor of China, and there is a shortage of water resources. The average annual precipitation meter is 620 mm. It seeks to improve the utilization of limited water conservancy resources and reduce the leakage loss of water transmission and water storage projects. Therefore, Shigong membrane is used to solve the problem of anti-seepage. . With the development of geosynthetic material technology, Shigong membrane has gradually been widely used in various anti-seepage projects. At present, Suizhong City has widely applied Shigong membrane to prevent seepage in projects Geomembrane liner for canals and reservoirs, and has received good economic benefits and technical effects.

Geomembrane liner for canals :

The irrigation canal in Suizhong County, Liaoning Province was built in the 1970s. The designed irrigation area of the paddy field is 35,000 mu. The soil quality in this area is mostly sandy loam. The irrigation area is infiltrated seriously, and the irrigation water utilization coefficient is only 50%. The utilization coefficient is increased to 96%. The designed water diversion flow of this channel is 9.2m3/S, the normal water level is 0.85m, the geomembrane is fully buried, the slope ratio of the embankment is 1:1.35, and the soil protection of not less than 0.35M is set on it. In order to enhance the anti-slip stability of the geomembrane, a saw-tooth wall is added at one-half of the water depth. The canal section is more than 20 kilometers long. After the project is completed, it has received a good anti-seepage and water-saving effect.

Reservoir geomembrane

Geomembrane liner for  reservoirs:

In Suizhong city, a number of earth dams have been built by using geomembrane instead of the clay wall anti-seepage layer, which has achieved obvious economic benefits. The specific construction method is to use geomembrane instead of the clay wall. The upper and lower parts of the geomembrane use a 30cm-thick sand protection layer. The connection between the geomembranes must be tight and watertight. The construction and the dam body construction are carried out simultaneously. In the construction, the geomembrane not only reduces the project cost, but also has a more ideal anti-seepage effect.

TINM brand geomembrane is added with anti-oxidation and anti-ultraviolet components, and the service life is more than 20 years
