Matters Needing Attention In Geomembrane Construction
Geomembrane is a kind of anti-seepage material made of macromolecule polymer, which can prevent both liquid leakage and gas volatilization. Geomembrane (> 0.8mm thick) is usually called waterproof board and <0.8mm is called geomembrane. It is a kind of anti-seepage material made of macromolecule polymer, which is divided into homogeneous geomembrane and composite geomembrane. It is widely used in construction, transportation, subway, tunnel, and engineering construction.
The following points should be paid attention to in the construction of geomembrane.
1. It depends on the design contract and construction quotation. Generally, it is calculated according to the area. Note: If there is a slope, multiply it by the slope coefficient.
2. Construction specifications, whether the overlap of high quality aquaculture geomembrane is qualified, if not design specifications, the corresponding reduction of the amount of work, if necessary, to rework.
3. According to the design specifications, to see the local contact (if it is mechanically fixed) to see the rivet (tie) treatment, according to the number of contact points calculated.
4. Composition of local structures. For example, the trench, anti-high treatment, and edge-closing treatment, according to your personal relationship and the quality of the project, you can appropriately give twice the measurement area, because the backpack part itself is made of two layers.
