Water outlet energy dissipation and scour prevention structure related to urban river channel construction exposed pipe diversion
The invention provides a water outlet energy dissipation and scour prevention structure related to urban river channel construction exposed pipe diversion. The water outlet energy dissipation and scour prevention structure comprises an energy dissipation box, an anti-scour protection bottom and an energy dissipation box fixing platform used for supporting the energy dissipation box upwards, all of which are sequentially arranged in the flow direction. The energy dissipation box is composed of a bottom plate, two side walls and a rear baffle, a flow guide water pipe is arranged on the rear baffle, the flow guide water pipe is communicated with the space in the energy dissipation box, and a plurality of energy dissipation teeth are arranged on the bottom plate; a heap energy dissipation part is arranged on the portion, close to the anti-impact bottom protection side, of the bottom plate and used for enhancing the energy dissipation effect of the energy dissipation box on water flow. The multiple energy dissipation teeth are arranged on the bottom plate of the energy dissipation box to assist in energy dissipation, the heap energy dissipation part is arranged on the portion, close to the anti-impact bottom protection side, of the bottom plate to generate hydraulic jump energy dissipation, the energy dissipation effect of the energy dissipation box on water flow can be jointly enhanced, meanwhile, a channel formed by the energy dissipation teeth is beneficial to prolonging the path of the water flow, and therefore the good hydraulic energy dissipation effect is achieved.
本发明提供一种涉城市河道施工明管导流的出水口消能防冲结构，包括沿着流向依次设置的消能箱、抗冲护底以及用于向上支撑消能箱的消能箱固定平台；所述消能箱由底板、两个侧壁以及后挡板组成，所述后挡板上设有导流水管，所述导流水管与消能箱内空间相连通，所述底板上设有多个消能齿；所述底板在靠近抗冲护底侧设置壅高消能部，所述壅高消能部用于增强消能箱对水流的消能作用。本发明在消能箱的底板上设有多个消能齿辅助消能，且在底板靠近抗冲护底侧设置壅高消能部产生水跃消能，可以联合增强消能箱对水流的消能作用，同时消能齿所形成的通道有利于延长水流的路径，从而达到较好的水力消能效果。
