Abstract
The invention discloses an anti-seismic water stopping structure for a stone dam. The anti-seismic water stopping structure comprises a high-toughness cement-base composite material layer. Two expansion bolts are disposed on the high-toughness cement-base composite material layer. An elastic edge sealing device is connected between the two expansion bolts. A through hole is formed in the middle of the elastic edge sealing device. A rubber cover is disposed in the through hole. An anti-seepage cover is disposed in the rubber cover and connected with the same through the expansion bolts. The opening of each of the anti-seepage cover and the rubber cover is connected to the upper surface of the high-toughness cement-base composite material layer. A V-shaped groove is formed in a position, corresponding to the opening of the anti-seepage cover, of the high-toughness cement-base composite material layer. The anti-seismic water stopping structure has the advantages that good anti-seismic and water stopping effects are achieved, the structure is suitable for high earth-stone dams in strong-earthquake areas, deformation resistance of concrete panels can be increased effectively, staggering of the concrete panels under earthquakes can be prevented, high reliability is achieved, and seepage cannot be caused easily.
