Yunnan Province, Qujing City, a pig farming base with 300,000 native pigs, has implemented a leachate pool impermeability project with a capacity of 50,000 cubic meters. The project uses a single-layer 1.5mm smooth geomembrane impermeability structure. During the geomembrane installation, leakage and damage detection was conducted, revealing two leakage points at the welds and five at mechanical damage sites. After on-site technicians repaired the welds by squeezing, the project passed the electrical discharge testing without issue.
