Double-deck concrete faced rock-fill dam and construction method thereof
The invention discloses a double-deck concrete faced rock-fill dam. The double-deck concrete faced rock-fill dam comprises a rock-fill accumulation body, a concrete face, geo-membrane and a super-polymer compound concrete face, the upper side of the rock-fill accumulation body is laterally covered with the super-polymer compound concrete face, the super-polymer compound concrete face is covered with the geo-membrane, and the geo-membrane is covered with the concrete face. The invention also discloses the double-deck concrete faced rock-fill dam construction method. According to the double-deck concrete faced rock-fill dam and the construction method thereof, the filling requirement to the accumulation body of a dam body is relatively lower, and it is avoided that a normal concrete faced rock-fill dam requires a higher degree of filling density and a loaded filter with impermeability in the process of filling; concrete hydration heat is effectively reduced, and construction links are few; the impermeability ability of the dam body is enhanced, and the loaded filter and a transition layer are not needed to be constructed on the back of concrete faces; the geo-membrane is arranged between double-deck concrete faces, and self compact concrete can be effectively protected from flowing into the accumulation body; the double-deck concrete faced rock-fill dam construction method has the advantages of being fast in construction speed, simple in process, suitable to popularize and apply and good in practicability.
