HDPE Geomembrane Application:
(1)Aquaculture:
Using the geomembrane anti-seepage feature; geomembrane liners can be used as fish ponds, shrimp pond, tank liner and others.
(2)Landfill:
HDPE geomembrane is the most widely used in landfill anti-seepage engineering material. The use of main parts of the bottom of the landfill liner, landfill sealing cover, leachate regulating pool liner, etc.
(3)Water Treatment System :
HDPE geomembrane is applied to the adjustment of the power plant and sewage treatment plants pool;and a series of water treatment systems.
(4)Mining:
HDPE geomembrane suitable mining: washing pool, pool heap leaching, heap yard, dissolving tank, tank, storage area, the bottom line of the tailings seepage control, etc
Construction Method
1. The slope shall be laid in order from top to bottom. Don’t pull it too tight.
2. Tow adjacent longitudinal joints should not be in a horizontal line, should bestaggered more than 1m each other.
3. Longitudinal joints should be more than 1.50m away from the dam foot and bending foot, and should be located on the plane.
4. When the slope is laid, the direction of spreading film should be basically parallel to the slope line.
5. The construction, first of all to use small diameter sand or clay levelingbase, and then laid the geomembrane. The geomembrane should not be stretched too tight, and the part of the soil bured at both ends is corrugated. A transitional layer of about 10cm is laid on the geomembrane with sand or clay.
