Abstract

The invention discloses a composite panel earth rockfill dam and an anti-seepage body construction method. The composite panel earth rockfill dam comprises a capsule blanket, a panel seat, a composite panel, a wave-resistant wall, a transitional layer, an earth dam body and the like, wherein the cross section of the composite panel earth dam is ladder-shaped; the wave-resistant wall is arranged at the dam top; the capsule blanket is tiled on the upstream river bed; the panel seat from the river bed to dam abutments on two sides is arranged at the upstream toe; a drape is arranged below the panel seat; the composite panel is arranged on the whole upstream dam slope surface; the bottom surface of the composite panel is connected with the panel seat; the top surface of the composite panel is connected with the wave-resistant wall; the inclined transitional layer with thin upper part and thick lower part is arranged between the composite panel and the earth dam body; a stone revetment and a packway are arranged on the downstream dam slope surface; and a slope-clinging drainage body is arranged at the downstream toe; and the capsule blanket, the resin film seal, the panel seat, the drape, the composite panel, the dam abutment on both sides and the wave-resistant wall form the closed anti-seepage body. The composite panel earth rockfill dam is suitable for being built on rock, gravel, earth and other different dam foundations, has the characteristics of high water storage level, good anti-seepage effect, simple structure, simplicity and convenience in construction and the like, and is a novel water-retaining building in the reservoir pivot.

Description

technical field [0001] The invention relates to an earth-rock dam using a composite material face plate as an anti-seepage and slope protection material and a construction method thereof, in particular to an earth-rock dam with a composite material face plate and a construction method for an anti-seepage body thereof. Background technique [0002] At present, the face of the face rock dam often adopts reinforced concrete structure. Due to the high rigidity of the reinforced concrete face, the earth rock dam supporting the reinforced concrete face is a loose body. It is difficult to coordinate the deformation, which often leads to the void at the bottom of the reinforced concrete slab. Under the action of water storage pressure, self-weight, wind and waves and other loads, the reinforced concrete slab cracks, which affects the safety and normal operation of the dam. Contents of the invention [0003] Aiming at the deficiencies of the existing face-face earth-rock dam face, ...
