A flying wing type toe pier stilling basin

Abstract

The utility model discloses a kind of flying wing toe piers, which is composed of gate pier, spillway, flying wing toe pier, stilling basin, side wall and tail sill;The gate pier is arranged at one end of the stilling basin, and the water flows through the spillway into the bottom of the stilling basin;The side wall is arranged on both sides of the stilling basin;The tail sill is arranged at the other end of the stilling basin;The flying wing toe pier is arranged at the tail end of the spillway, and the tail is flush with the end of the reverse curve section of the spillway, arranged at equal intervals.The flying wing toe pier is different from the traditional toe pier in that the height of the tail is different, and it can adapt to different flow conditions.The reduction of the bottom flow velocity and the improvement of the energy dissipation efficiency reduce the length of the stilling basin and the impact pressure of the bottom plate, thereby reducing the investment of the entire stilling basin.
