What Is The Composite Geomembrane, How To Define?
Jun 08, 2017

Composite geomembrane is in the film on one or both sides of the oven through the far infrared heating, the geotextile and geomembrane through the guide roller together to form a composite geomembrane. With the improvement of production technology, there is a casting method to do composite geomembrane technology. Its form has a cloth a film, two cloth a film, two film a cloth and so on.

Geotextile as a protective layer of geomembrane, so that the protection of impermeable layer from damage. In order to reduce the UV radiation, increase the anti-aging properties, it is best to use the laying method.

Construction, the first use of smaller diameter sand or clay to find the base surface, and then laying geomembrane. Geomembrane should not be stretched too tight, buried at both ends of the soil part of the corrugated, and finally in the shop on the geomembrane with a fine sand or clay layer of a layer of about 10cm transition layer. Puzzle 20-30cm stone (or concrete prefabricated block) for the anti-Chong protective layer. Construction, should try to avoid the stones directly hit the geomembrane, the best side of the film side of the protective layer of the construction. Composite geomembrane and the surrounding structure should be connected with expansion bolts and steel plate pressure bar anchorage, the connection site to brush the emulsion asphalt (2mm thick) bonding, to prevent the occurrence of leakage.

Determination of Freezing Pressure of Composite Geomembrane

Composite geomembrane is made of geotextile and geomembrane composed of impervious material, which is mainly used for seepage, composite geomembrane is divided into a cloth and a film of two cloth, wide 4-6m, 1500g / m2, tensile, tear, broken and other physical and mechanical properties of high indicators, to meet the water conservancy, municipal, construction, transportation, subway, tunnel and other civil engineering needs. Because of its choice of polymer materials and the production process to add anti-aging agent, it can be used in non-conventional temperature environment.

Composite geomembrane (composite impermeable membrane) is divided into a cloth and a film of two cloth, wide 4-6m, tensile, tear, broken and other physical and mechanical properties of high index, the product has high strength, Better deformation modulus, Naisuan Jian, anti-corrosion, anti-aging, anti-seepage performance and so on. To meet the water conservancy, municipal, construction, transportation, subway, tunnel, construction in the seepage, isolation, reinforcement, crack reinforcement and other civil engineering needs. Commonly used in the dam, drainage ditch of the anti-seepage treatment, as well as waste field anti-fouling treatment.
