During construction, the thermal expansion and shrinkage deformation and expansion of the material should be maintained. The laying of the geomembrane should be completed daily to reduce wrinkles and drag, and do not pull it too tightly, otherwise the geomembrane will be damaged due to excessive local deformation. The leachate drainage layer is generally made of gravel or crushed stone, and the thickness is not less than 30 cm. The leachate drainage layer of the landfill in this area has a large amount of stone paving. How to solve the problem of sand transportation on the geomembrane It is very important to prevent damage to the geomembrane during the process of the booth. In this project, after many on-site test and construction work, every four pieces of geomembrane are laid as a unit of work. Geotechnically lay a 5mm thick steel plate material transportation channel, and pave a gravel road with a thickness of more than 1.5 meters according to a certain distance. While using an excavator to stand on the gravel road from the inside out. Anti-leak detection, this construction measure has a better protective effect on the geomembrane, and the damage of the geomembrane is small.
