Flow deflecting energy dissipation structure suitable for curve river spillway
The flip bucket energy dissipation structure comprises a flood discharge groove and flip bucket noses, and is characterized in that a middle partition wall is arranged in the flood discharge groove, the middle partition wall divides the flood discharge groove into more than two flow channels, the flip bucket noses are arranged at the tail ends of the flow channels respectively, all the flip bucket noses are combined to form a plane differential type arrangement structure, and the plane differential type arrangement structure is arranged on the flood discharge groove. The starting point positions of the flip bucket bodies are different, the distance between the tail ends of the flip bucket bodies and the riverbed is gradually increased from the upstream to the downstream, the distance difference between the tail ends of the adjacent flip bucket bodies and the riverbed is 10-30 m, the tangent points of the lifting positions of the left side and the right side of each flip bucket body are different, and the lifting angle of each flip bucket body is 25-35 degrees. The lifting angles of the left side and the right side of the flip bucket are the same or different. By the adoption of the flip bucket, it can be guaranteed that the flip bucket has the better flip bucket energy dissipation effect than a traditional spillway, the water flow discharged from the spillway on a curve river can be promoted to smoothly enter a downstream river channel, and therefore scouring damage to the river channel and a bank slope is avoided.
本发明涉及适宜于弯道河流溢洪道的挑流消能结构，包括泄洪槽和挑流鼻坎，其特征是所述泄洪槽内设置有中隔墙，中隔墙将泄洪槽分隔成两个以上的流道，各流道的末端分别设置挑流鼻坎，全部挑流鼻坎组合形成平面差动式布置结构，各挑流鼻坎的起点位置不同，各挑流鼻坎的末端与河床之间的距离自上游至下游递增，相邻挑流鼻坎的末端与河床之间的距离差为10m‑30m,挑流鼻坎左右两侧起挑位置的相切点不同，挑流鼻坎的起挑角度为25°‑35°，挑流鼻坎左右两侧的起挑角度相同或者不同。采用本发明，既可以保证挑流鼻坎具有比传统溢洪道更好的挑流消能效果，又可以促使弯道河流上的溢洪道下泄水流顺利进入下游河槽，从而避免对河槽和岸坡的冲刷破坏。
