Its purpose is to withstand floodwaters and prevent them from penetrating the dam, thereby ensuring its strength and stability.
[0003] When the existing water conservancy flood control embankment structure is in use, the water-facing side of the dam body is paved with a rock layer, in which there are many gaps between the rocks, and the cement slurry injected has a poor filling effect, which affects the anti-seepage quality. In addition, the water-facing side of the dam body is usually paved with a geomembrane, but its tensile strength is relatively low and it is easily damaged by external forces. Regular maintenance is required, which greatly increases the investment cost. Utility Model Content
