Embodiment Construction
[0020] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0021] as attached Figures 1 to 3 As shown, this embodiment discloses a flood discharge building, which is used as a water conservancy and hydropower project for flood discharge and energy dissipation. It has a flood discharge structure that uses a combination of bottom holes and surface holes. The method improves the energy dissipation rate in the stilling pool, and can significantly reduce the scouring effect of the discharged water on the bank slope.
[0022] Specifically, such as figure 1 and 2 As shown, the flood discharge structure includes: a surface hole flood discharge unit 10 and a bottom hole flood discharge unit 20, which are arranged in sequence from top to bottom along the vertical direction of the flood discharge building, so that when the flood discharge flow is small, only the bottom hole is used for flood discharge. The un...
