Description

TECHNICAL FIELD

[0001] The present application relates to a geomembrane pond lining system, belonging to the technical field of geomembrane. BACKGROUND

[0002] The geomembrane is a kind of waterproof barrier material with polymer as basic raw material, which is widely used in flexible anti-seepage system such as water storage pond, breeding pond, evaporation pond and used as the main anti-seepage layer. Compared with the lining system made of soil, concrete and steel, it has the advantages of good anti-seepage performance, good corrosion resistance, easy construction and low cost.

[0003] In the prior art, the geomembrane is usually covered on the top of the flattened pond, and extends out of the outside of the pond, and is anchored. The anchoring function is to prevent the geomembrane from being pulled out of the edge of the geomembrane under the pressure of water or other medium filled into the pond, so as to cause the failure of the anti-seepage system. This installation method causes that the geomembrane except the submerged part in the pond and the anchoring part is in an exposed state. On the one hand, the geomembrane as a flexible anti-seepage layer made of polymer has a smooth surface, and people or animals walking on the exposed part are easy to slip; on the other hand, the exposed part of the geomembrane is easy to reduce the service life due to the influence of ultraviolet rays, oxygen and temperature, and the anchoring part of the slope is also easy to slip due to the insufficient friction between the geomembrane and the foundation.
