Upstream-oriented seepage-proofing and crack-resisting roller-compacted concrete gravity dam
The invention discloses an upstream-oriented seepage-proofing and crack-resisting roller-compacted concrete gravity dam. The dam comprises a dam body, a dam body top layer and a dam body cushion layer, wherein a seepage-proofing and crack-resisting protection layer is arranged on the dam body in the manner of facing the upstream; a transition combining layer is arranged between the seepage-proofing and crack-resisting protection layer and the dam body; a draining galleries are respectively arranged at each one third elevation in the dam body; a dam body reversed filtering layer is arranged on the upper part of the dam body cushion layer; a plurality of longitudinal draining pipes are arranged on the side, close to the upstream of the dam body and are in straight-through type connection with the draining galleries; transverse draining pipes are arranged on the draining galleries on the lowest layer along the horizontal direction. After entering the draining galleries from the longitudinal draining pipes, penetrated water flows to or is drained to the downstream by a water pump through the transverse draining pipes. The dam is good in seepage resistance and crack resistance, and high in durability, and the practicability and the durability of the structure are guaranteed.
