Dam spillway structure and construction method thereof
The invention relates to a dam spillway structure and a construction method thereof. The dam spillway structure comprises an obliquely-arranged spillway body bottom plate, a first side plate and a second side plate, wherein the first side plate and the second side plate are formed on the upper end face of the spillway body bottom plate; one end of the spillway body bottom plate is provided with aninlet, and the other end of the spillway body bottom plate is provided with an outlet; the spillway body bottom plate inclines downwards from the inlet to the outlet; a plurality of step bodies are arranged at the upper part of the spillway body bottom plate in the drainage direction; each step body comprises a flat surface and a vertical surface; a vent groove is formed in each vertical surface;each vent groove extends in the extending direction of the corresponding step body; one end of each vent groove penetrates through the second side plate; and gas is introduced into each vent groove.The dam spillway structure has the effect of improving the energy dissipation rate of a spillway.
本申请涉及一种大坝溢洪道结构及其施工方法，其包括倾斜设置的道体底板、成型在道体底板上端面的第一侧板和第二侧板；道体底板的一端为进口处，另一端为出口处，道体底板自进口处向出口处呈向下倾斜设置；道体底板上部沿其排水方向设置多个台阶体；台阶体包括平直面和竖直面；竖直面上开设有通气槽，通气槽沿台阶体的延伸方向延伸且一端贯穿第二侧板，通气槽内通入气体。本申请具有提高溢洪道消能率的效果。
