Face-picking mixed flow energy dissipation type
The invention discloses a face-picking mixed flow energy dissipation type, and aims to solve the problems that a face-picking energy dissipation type in the prior art often has a deep scouring pit and influences the safety of a dam for some projects with high water heads, small downstream water depth and weak bedrock impact resistance. According to the novel face-picking mixed flow energy dissipation type, energy can be eliminated through collision and spiral rolling of two forms of water flow in a downstream river channel, and finally scouring to a downstream riverbed is relieved. According to the technical scheme, the face-picking mixed flow energy dissipation type comprises a low flip bucket and a high flip bucket which are arranged below a flood discharge hole of a dam, and the tail end elevation of the high flip bucket is larger than that of the low flip bucket. The face-picking mixed flow energy dissipation type is suitable for energy dissipation and scour prevention of release structures in water conservancy projects.
本发明公开了一种挑面混合流消能型式，旨在克服现有技术中的挑流消能型式对于一些水头高、下游水深较小、基岩抗冲能力较弱的工程，挑流消能往往存在冲坑偏深，影响大坝安全的问题。本发明的目的是提出一种新的挑面混合流消能型式，能够通过两种形式水流在下游河道的碰撞、漩滚消杀能量，最终减轻对下游河床的冲刷。本发明的技术方案是：本发明的一种挑面混合流消能型式，包括设置在大坝的泄洪孔口下方的低挑流坎和高挑流坎，所述高挑流坎的末端高程大于低挑流坎的末端高程。本发明适用于水利工程中泄水建筑物的消能防冲。
