The geomembrane at the bottom of the reservoir can be laid after excavation and filling of the dam in the reservoir area.
The construction quality control of composite geomembrane includes the quality control of raw materials and the quality control of the construction process.
1. Cover the mulberry garden with Horticulture Weed Barrier, which can increase the soil temperature and moisture content, and has a moisture preservation effect on the soil.
1. Polyester non-woven fabric is the golden partner of drainage board, which can filter water and hold the soil layer. The colors are generally black, yellow, white, gray, etc. Minimum specifications: width; 2 meters, 100 meters long. 2. Polyester non-woven fabric products are non-woven geotextiles reinforced by polyester continuous filaments. The tensile strength is ≥8KNm, and the elongation is 40-60%, which fully meets the requirements of Jr/ To1g98 (Road Shigong Synthetic Material). The technical requirements for geotextiles in the application technical specifications).
The geomembrane has a very low permeability coefficient and is widely used in the lining system of landfills.
The quality of the geomembrane itself is very important to the safety protection of the river embankment. When transporting geomembrane, it should not damage or pollute the environment, and long-term contact should be avoided.
