Application technology of composite geomembrane production line!

Composite geomembrane is an impermeable material composed of geotextile and geomembrane. It is mainly used for anti-seepage. The composite geomembrane is divided into one cloth and one membrane and two cloths and one membrane. 1500g/m2, high physical and mechanical performance indicators such as tensile strength, tear resistance, bursting, etc., can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, etc. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.

The composite geomembrane is heated by far infrared in an oven on one side or both sides of the membrane, and the geotextile and the geomembrane are pressed together by a guide roller to form a composite geomembrane. With the improvement of production technology, there is also a process of making composite geomembrane by casting method. Its form has one cloth and one film, two cloths and one film, two films and one cloth, etc. The geotextile is used as the protective layer of the geomembrane to protect the impermeable layer from damage. In order to reduce ultraviolet radiation and increase anti-aging performance, the buried method is used for laying.

During construction, first use sand or clay with a smaller diameter to level the base surface, and then lay geomembrane. The geomembrane should not be stretched too tightly, and the buried soil at both ends is corrugated. Finally, a transition layer of about 10cm is laid on the geomembrane with fine sand or clay. A 20-30cm block stone (or prefabricated concrete block) is built as an impact protection layer.

During construction, try to avoid the stones hitting the geomembrane directly, and construct the protective layer while laying the membrane. The connection between the composite geomembrane and the surrounding structures should be anchored by expansion bolts and steel plate battens, and the connection parts should be painted with emulsified asphalt (thickness 2mm) to prevent leakage.
