Introduction And Construction Of Composite Geomembrane For Requirements
Dec 12, 2016

Composite Geomembrane is a member of the large family of geo-synthetic material, widely used in road, railway, water conservancy, large buildings, power plant fly ash dam construction, nonferrous metal mine tailings management, environmental engineering, soil and water conservation, and so on.

Composite geomembrane service life problems, mostly from seepage water and the film lost, according to the national standards of the Soviet Union, hydraulic with thickness of 0.2m and stabilizer of polyethylene film, length up to 40-50 in water conditions, work in sewage conditions for 30-40. Composite geomembrane service life is sufficient to meet the requirements of dam seepage control life.

Product variety: a cloth one membrane, two cloth one membrane, membrane, etc.

Features: set of anti-seepage and drainage in one, high strength, friction coefficient, puncture-resistant, anti-aging, acid, to prevent soil erosion.

Construction of composite geomembrane

Composite Geomembrane is labeled geotextile on one side or both sides of the film to form a composite geomembrane. In the form of a cloth of a film, two cloth one membrane, a cloth two membrane.

As geomembrane geotextile layer, impervious layer of protection from damage. In order to reduce ultraviolet radiation increase anti-aging properties, the best use of embedding the laying.

Construction of the first small material size of sand or clay to find pinky, then lay the geomembrane. Don't stretched too tightly geomembrane, corrugated shape of buried body parts at both ends, finally paving geomembrane on fine sand or excessive layers of clay a layer of 10cm. 20-30cm on stone masonry (or precast concrete block) for erosion protection layer. Construction, every effort should be made to avoid stones directly on the geomembrane, preferably side boundary layer of film construction. Composite geomembrane and its surrounding structures connected by expansion bolts and steel bead anchor, connecting parts painted in emulsified asphalt (2mm) bonded to prevent the leakage.
