Anti-seepage geomembrane plays an important role in dike waterproof work

The anti-seepage geomembrane plays an important role in the waterproof work of embankments and upright dams. Since the end of the last century, it has been widely used, especially in the waterproof work of granular formations. The process can effectively work the more dangerous seepage, and can also play a role in the basic waterproof work.

It can be seen from many practices that the significant advantage of the concrete cut-off wall process is that it can effectively control the proportion and depth of materials, is safe and practical, but the cost is relatively high. In the selection of materials, waterproof technology is generally used. As everyone knows, no matter which material is selected, a corresponding proportion of waterproof agent should be added to better improve the waterproof characteristics of the project. The operation of the impermeable membrane process is relatively simple and convenient. It mainly uses basic materials such as anti-seepage geomembrane and composite geomembrane. The location of the dam to be treated is waterproof to the dam. If combined with other waterproof measures, the waterproof effect will be more significant. In addition, the waterproof film material has better extensibility, is not easy to crack, and has low permeability, so it has been used in many emergency projects.

The anti-seepage geomembrane is composed of short fiber geotextile or filament geotextile and high-density polyethylene geomembrane. The composite geomembrane can be divided into two layers of cloth, one layer of film and one layer of cloth, one layer of film, the width is 1-6m, and the weight is 200-1500g/m2. The composite geomembrane has smooth drainage and good waterproof properties.
The composite geomembrane is made of polymer materials, and anti-aging agents are added in the production process, which can be used in unconventional temperature environments. It is usually used for waterproofing of dams, drainage ditches and rivers and pollution prevention of waste sites.
Composite geomembrane has high physical properties, such as tear resistance, tensile strength and fracture resistance. The composite geomembrane has high strength, good elongation, anti-aging, acid resistance, corrosion resistance and impermeability. The composite geomembrane can meet the requirements of civil engineering, such as waterproof, reinforcement, isolation and crack reinforcement in engineering construction, water conservancy engineering, municipal engineering, subway station, traffic travel, tunnel and engineering construction.
