Abstract

The invention discloses a wharf pile foundation scouring protection device which comprises a flow stopping protection mechanism, a protection cylinder mechanism, multiple buffering slopes and multipleflow stopping assemblies. The flow stopping protection mechanism comprises a fixing ring, a reinforcing ring and multiple connecting plates, wherein the fixing ring, the reinforcing ring and the connecting plates are arranged coaxially. The protection cylinder mechanism comprises a first protection cylinder, a second protection cylinder and multiple flexible buffering plates. The tops of cylinderbodies are closed. Multiple first through holes and multiple second through holes are formed in the surface of the first protection cylinder and the surface of the second protection cylinder correspondingly. The multiple buffering slopes are arranged uniformly in the radial direction of a pile foundation in a dispersing manner. Each flow stopping assembly comprises a pair of guide plates arrangedon the connecting plates, sliding grooves in the middle portions of the guide plates, multiple reset springs, multiple buffering blocks, flow stopping rods arranged in the sliding grooves in a sliding and penetrating manner, and limiting nuts arranged at the two ends of the flow stopping rods in a sleeving manner. The protection cylinder mechanism, the buffering slopes and the flow stopping assemblies are arranged in the radial direction of the pile foundation from inside to outside. The scouring protection device has the beneficial effects that energy of water flow is dissipated, scouring ofthe water flow to the pile foundation is reduced, the pile foundation is protected, and the stability of the pile foundation is improved.

Description

technical field [0001] The invention relates to the technical field of building protection. More specifically, the present invention relates to a scouring protection device for pier pile foundations. Background technique [0002] In marine construction engineering, pile foundation is an essential part of constructing and supporting the superstructure, and its stability is an important basis for ensuring the quality of the building. After the platform is built, the pile group will change the original hydrodynamic field in this area. The flow field structure around the pile mainly includes surge waves on the water surface in front of the pile, water flow and vortex on the upstream side. The negative pressure at the center of the vortex will suck up the sand on the bed surface and carry it downstream. With the generation of the vortex, the static sediment on the bed surface will move randomly, and the vortexes on both sides downstream of the pile will meet to form a sand ridge...
