Inlet water energy dissipation structure of regulation and storage facility

YUAN TINGXUAN / ZHU RENXIAO

The invention relates to the technical field of rainwater regulation and storage engineering, in particular to a water inlet energy dissipation structure of a regulation and storage facility, which comprises a water inlet pipe, a water inlet cushion, a retaining ridge and a water storage structural body, a water inlet is formed in one side end wall of the water storage structural body close to the top, the water inlet pipe is arranged in the water inlet in a penetrating manner from the outside, and the water inlet cushion is arranged on the inner side wall of the end wall. The water inlet cushion extends towards the interior of the water storage structure, the blocking ridge is arranged on the inner bottom face of the water storage structure, a containing space with an opening in the top is defined by the blocking ridge and all the inner walls of the water storage structure, and the orthographic projection of the water inlet cushion towards the inner bottom face of the water storage structure is located in the containing space. According to the water inlet energy dissipation structure of the regulation and storage facility, water inlet energy dissipation can be achieved by means of primary buffering of the water inlet cushion and secondary buffering of water in the containing space, and water falling noise and erosion to the bottom of the regulation and storage pool are prevented.

本发明涉及雨水调蓄工程技术领域，尤其涉及一种调蓄设施的进水消能结构，包括进水管、进水水垫、挡坎和蓄水构造体，蓄水构造体的一侧端墙在靠近顶部位置开设有进水口，进水管从外部穿设在进水口内，进水水垫设置在端墙的内侧壁上，且进水水垫向蓄水构造体的内部方向延伸，挡坎设置在蓄水构造体的内底面上，且挡坎与蓄水构造体的各向内壁围构出顶部开口的容置空间，进水水垫向蓄水构造体内底面上的正投影位于容置空间内。该调蓄设施的进水消能结构能够借助进水水垫的一次缓冲和容置空间内水体的二次缓冲，实现进水消能，防止落水噪声和对调蓄池池底的侵蚀。
