Geomembrane Laying Is Divided Into Two Parts

Geomembrane laying is divided into two parts: Plane laying and elevation laying. After acceptance of the geomembrane, lay the surface and pave the road. The plane is placed from east to west, and the front is placed from bottom to top. Road paving should be carried out in a dry and warm climate. In order to facilitate splicing and avoid stress accumulation, the geomembrane should be strictly controlled when laying, with a residual of about 1. 5%. After laying, the geomembrane is flattened and pulled away in real time, and the geomembrane and surface are flat without raised wrinkles.

Construction workers must wear flat shoes or soft rubber shoes. It is strictly forbidden to wear long nails to avoid geomembrane. If the geomembrane is damaged during construction, it should be repaired in time. Since polyethylene is a petroleum product, it can absorb other petroleum products. Like a sponge, this material will increase in thickness and become more flexible, but will not produce small or mesopores. Which adsorption is different from sponge is not direct.

Sieve out a 10 cm thick geomembrane protective layer. Particles larger than 6mm in diameter are not allowed. Otherwise, the geomembrane can be easily punctured. The soil protection layer should be dense and the weight should be greater than 1. 5. Sampling inspection should be carried out at any time. When backfilling the protective layer and masonry surface, it should be placed gently to avoid damage to the geomembrane.

Under the surface of the stone, the geomembrane should be filled with 100 mm thick gravel or gravel cushion to avoid the soil protection layer caused by water level changes, wind and waves and other factors. Dry masonry uses artificial hanging wire. When paving, the stones should be tightly packed, the personal weight of the surface stones should be greater than 48 kg, and all voids should be filled with small stones.

After laying the geomembrane, sand and soil should be applied to prevent the wind from moving. The seams at the edges must be clean and free of debris.

Put it on a clear goal. Geomembrane reserves 10-20 cm edge for welding. When laying, it is necessary to adjust the display program of the geomembrane to facilitate the welding of the geomembrane.
