The invention relates to a bridge pier with a partitioned vortex elimination function and an anti-scour assembled retainer. The anti-scour assembled retainer comprises a bridge pier arranged in water; the pier front vortex elimination groove body is arranged on the upstream side of the pier and is provided with a first cavity and a first opening, the first opening is used for enabling part of coherent vortex water flow formed by the downward flowing water flow to enter the first cavity, and the pier front vortex elimination groove body is used for weakening the transverse axis vortex on the upstream side of the pier and the strength of the downward flowing water flow; the two pier side vortex elimination groove bodies are arranged on the two opposite sides of the pier front vortex elimination groove body, the pier side vortex elimination groove bodies communicate with the pier front vortex elimination groove body, and the pier side vortex elimination groove bodies are used for consuming and disturbing the flow direction of pier side part compressed water flow. The two pier side vortex elimination groove bodies are arranged on the pier side, the pier rear vortex elimination plate is arranged on the downstream side of the pier, the two ends of the pier rear vortex elimination plate are connected with the two pier side vortex elimination groove bodies correspondingly, and the pier rear vortex elimination plate is used for weakening the vertical axis vortex strength of the downstream side of the pier, so that partition vortex elimination can be conducted on different areas of the pier, and local scouring of the pier periphery of the pier can be reduced to the maximum extent.
Description
technical field [0001] The invention relates to the technical field of local scouring protection of bridge foundations, in particular to a bridge pier with partitioned vortex elimination and an anti-scouring assembled retainer. Background technique [0002] At present, when a bridge is built in a natural river, the water flow structure near it undergoes violent three-dimensional movement, which is mainly manifested as a complex vortex structure, which is one of the main reasons for local scour of bridge piers. The local scour around the pier is mainly caused by multiple quasi-sequential vortices formed in front of the pier due to the submerged flow, on the side of the pier due to the downstream movement of the vortex in front of the pier and the accelerated water flow caused by the lateral compression of the water flow, and behind the pier due to the separation of the side boundary of the pier It is jointly caused by the shedding wake vortex. It can be seen that the front a...
