What is geomembrane?

Geomembrane takes plastic film as the anti-seepage base material, and is compounded with non-woven fabric. The anti-seepage performance of new material geomembrane mainly depends on the anti-seepage performance of plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt blend geomembrane) is designed and used. They are polymer chemical flexible materials with small proportion, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance.

Characteristics of geomembrane

The composite geomembrane is made of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. Plastic films used for seepage prevention at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), ethylene/vinyl acetate copolymer (EVA), which are polymer chemical flexible materials with small proportion, strong extensibility, high deformation adaptability, corrosion resistance, low temperature resistance and good frost resistance.

The service life of composite geomembrane is mainly determined by whether the plastic film has lost its anti-seepage and water separation function. According to the national standard of the Soviet Union, the polyethylene film with a thickness of 0.2m and stabilizer for hydraulic engineering can work for 40 to 50 years in clean water and 30 to 40 years in sewage. Therefore, the service life of composite geomembrane is sufficient to meet the service life of dam anti-seepage requirements.

Scope of application of geomembrane

Zhoutou reservoir dam was originally a core dam, but due to dam collapse, the upper part of the core wall was disjointed. In order to solve the problem of seepage prevention in the upper part, an anti-seepage inclined wall was added. According to the safety demonstration and analysis of Zhoutou reservoir dam, in order to solve the problem of weak seepage surface and dam foundation leakage caused by multiple landslides of the dam, seepage prevention bodies such as bedrock curtain grouting, contact surface grouting, backfill curtain of grab sleeve well and high-pressure jet grouting seepage prevention board wall are adopted in vertical seepage prevention. The upper inclined wall is covered with composite geomembrane for seepage prevention. The lower part is connected with the vertical cut-off wall and the upper part is 358.0m high.

Performance characteristics of HDPE geomembrane

1. HDPE geomembrane is a flexible waterproof material with high anti-seepage coefficient (1 × 10-17cm/s）；

2. HDPE geomembrane has good heat resistance and cold resistance, and its operating environment temperature is 110 ℃ at high temperature and - 70 ℃ at low temperature;

3. HDPE geomembrane has good chemical stability and can resist the corrosion of strong acid, alkali and oil. It is a good anti-corrosion material;

4. HDPE geomembrane has a very high tensile strength, so that it has a very high tensile strength to meet the needs of high standard engineering projects;

5. HDPE geomembrane has strong weather resistance, strong anti-aging performance, and can be used naked for a long time to maintain the original performance;
