Anti-scour device for promoting siltation based on water flow self-energy consumption
The invention discloses an anti-scour device for promoting siltation based on water flow self-energy consumption. The anti-scour device comprises a pile sleeve, and a turbulent flow mechanism, a drainage mechanism and a protection bottom which are arranged around the peripheral side of the pile sleeve; two ends of the pile sleeve are through; the turbulent flow mechanism is used for decelerating and dissipating energy of water flow entering the turbulent flow mechanism; the drainage mechanism is separated from the peripheral wall of the pile sleeve, the drainage mechanism is provided with a backflow channel and a deposition inlet, the water inlet end of the backflow channel is connected and communicated with the water outlet end of the turbulent flow mechanism, and the deposition inlet is communicated with the backflow channel; the protection bottom is arranged in the enclosed space of the drainage mechanism, a sedimentation tank is formed in the space between the protection bottom and the drainage mechanism, and the sedimentation tank is communicated with the sedimentation inlet. After the anti-scouring device for promoting silt accumulation based on water flow self-energy consumption is adopted, energy consumption speed reduction treatment on descending flow in front of the pile is achieved, horseshoe vortexes around the pile and pile trailing vortexes are prevented from being generated, meanwhile, a near-bottom low-speed flow area is formed through seawater convection, silt is deposited, a sandy protective layer is formed, and scouring protection is conducted on the pile.
本发明公开了一种基于水流自耗能促进积淤的防冲刷装置，包括桩套筒、以及围绕桩套筒周侧布置的扰流机构、引流机构和护底；桩套筒两端贯通；扰流机构用于对进入其内部的水流减速消能；引流机构与桩套筒的外周壁相互分离，引流机构设有回流通道和沉积入口，回流通道的进水端与扰流机构的出水端连接导通，沉积入口与回流通道导通；护底置于引流机构围纳空间内，护底与引流机构的之间的空间形成沉积池，沉积池与沉积入口导通。在采用以上基于水流自耗能促进积淤的防冲刷装置后，实现了对桩前下降流的耗能减速处理，防止了桩周马蹄涡和桩尾涡的产生，同时利用海水对流形成近底低速流区，使泥沙沉积，形成砂质防护层，对桩柱进行冲刷防护。
