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.

- Geomembranes play a crucial role in the preservation of wildlife habitats by providing a protective barrier that helps prevent contamination and degradation of the surrounding environment. These impermeable liners are used in various applications, such as landfills, water containment, and wastewater treatment systems, to prevent the seepage of pollutants into the soil and water bodies. By effectively containing hazardous substances and preventing them from leaking into the habitat, geomembranes help maintain the ecological balance necessary for the survival of wildlife species. Additionally, these liners also aid in the restoration and rehabilitation of damaged habitats, ensuring the long-term preservation of wildlife.
- Q:How do geomembranes prevent leakage?
- Geomembranes prevent leakage by acting as a barrier between the containment area and the surrounding environment. These synthetic liners are impermeable to water, gases, and other substances, effectively preventing them from seeping through the containment system. Additionally, the installation of geomembranes involves proper welding or seaming techniques, ensuring a continuous, watertight seal that further enhances their ability to prevent leakage.
- Q:What are the techniques of foam concrete?
- With unique foam excitation technique, coal ash and other waste materials are mixed together in a scientific proportion, then they will become gold bricks—high-performance building blocks which can float on water with many advantages of lightweight, environmental protection, energy-saving and thermal insulation after going through many techniques of compulsory stirring, activation, foaming, output, casting molding. Special foaming agent is composed of several chemical raw materials in a certain proportion that are easy to buy. It will become light after foaming which is much more effective than that of most foaming agents sold in the market, but the price of it is 50% lower than that of most foaming agents sold in the market. High efficient curing agent is composed of several chemical raw materials in a certain proportion that are easy to buy, which greatly reduces cement quantity and cost. It has advantages of high strength and light weight, and enables non-autoclaved blocks (bricks) to reach and exceed the required strength of steam-cured blocks; MS innovative forming non-autoclaved blocks new molding technology, moulds can arbitrarily change the size of blocks in order to adapt to fit around the block sizes that walls need, which reduce the cost of moulds, and are convenient.
