Composite geomembrane (composite anti-seepage membrane)
is divided into one cloth and one membrane and
two cloths and one membrane
, wide,
Weight
is square meter, with high physical and mechanical properties such as tensile strength, tear resistance, and burst resistance. The product has high strength, good elongation performance, large deformation modulus, acid and alkali resistance, and corrosion resistance. , aging resistance, good anti-seepage performance and other characteristics. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, and anti-crack reinforcement in water conservancy, municipal administration, construction, transportation, subway, tunnel, and engineering construction. It is often used for anti-seepage treatment of dams and drainage ditches, as well as anti-fouling treatment of waste dumps.
Composite geomembrane
Construction
Composite geomembrane
One or both sides of the film are heated by far infrared oven, and the geotextile and geomembrane are pressed together through guide rollers Form a composite geomembrane. With the improvement of production technology, there is also a casting method to make composite geomembrane. Its forms include one cloth and one film, two cloths and one film, two films and one cloth, etc.
Geotextile serves as the protective layer of the geomembrane to protect the anti-seepage layer from damage. In order to reduce ultraviolet radiation and increase anti-aging properties, it is best to use the buried method for laying.
During construction, first use sand or clay with a smaller diameter to level the base surface, and then lay the geomembrane. Do not stretch the geomembrane too tightly. The parts buried in the soil at both ends will be corrugated. Finally, use fine sand or clay to lay a left and right transition layer on the geomembrane. Build a block of stones (or concrete prefabricated blocks) as an anti-collision protective layer. During construction, efforts should be made to avoid stones hitting the geomembrane directly. It is best to construct the protective layer while laying the membrane. The connection between the composite geomembrane and surrounding structures should be anchored with expansion bolts and steel plate battens, and the connection parts should be coated with emulsified asphalt (thick) for bonding to prevent leakage there.
Composite geomembrane
Construction matters
The use must be buried and the covering thickness should not be less than.
The renovation anti-seepage system should consist of a cushion layer, an anti-seepage layer, a transition layer and a protective layer.
The soil must be solid to avoid uneven subsidence and cracks, and turf and tree roots within the anti-seepage range must be removed. Sand or clay with small particle size is laid on the contact surface with the membrane as a protective layer.
When laying, do not pull the geomembrane too tightly. It is better to have the two ends buried in the soil in a corrugated shape. Especially when anchored with rigid materials, a certain amount of expansion and contraction should be left.
During construction, stones and heavy objects should be avoided from hitting the geomembrane directly. It is best to lay the membrane and cover it with a protective layer during construction.
Composite geomembrane is an impermeable material composed of
geotextile
and
geomembrane
. It is mainly used for anti-seepage. Composite geomembrane is divided into One cloth and one film, two cloths and one film, wide width, weight /, high physical and mechanical properties such as tensile strength, tear resistance, bursting, etc., can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subways, tunnels, etc. . Because it uses polymer materials and adds anti-aging agents in the production process, it can be used in unconventional temperature environments.
