Application and Quality Control of Composite Geotextile Membrane Anti-Seepage Inclined Wall in Roller Compacted Earth and Rock Dam Engineering
Due to its simple technology and convenient material selection,roller compacted earth and rock dams are often used as popular dam types for mining and water conservancy engineering facilities.To avoid the potential risks of water source pollution and ecological damage caused by non-ferrous metal leakage,it is crucial to take effective anti-seepage measures for the design and construction of dams.Aims to explore the solution of composite geomem-brane anti-seepage inclined wall,which forms a reliable anti-seepage barrier through the combination of multi-level structures,including long filament non-woven geotextile,double rough surface HDPE film,sodium based bentonite blanket,etc.It is anchored in the anti-seepage tooth groove 30 meters away from the dam foot.Through close inte-gration with the soil,an effective anti-seepage system is successfully constructed,providing useful experience and refer-ence for the design and construction of similar mining water conservancy engineering facilities.
