Flow guiding ridge structure on curve

The invention discloses a flow guiding ridge structure on a curve. The flow guiding ridge structure on the curve comprises a flow guiding ridge arranged on a concave bank of the curve of a riverbed, wherein the flow guiding ridge comprises an upstream face and a downstream face. The upstream face is a flat surface which is vertically arranged, wherein a concave cambered surface at one end of the flat surface is smoothly connected with the concave bank and a convex cambered surface at the other end of the flat surface is smoothly connected with a flow passing side of the flow guiding ridge. The downstream face is composed of a convex cambered surface and a concave cambered surface from top to bottom, wherein the convex cambered surface is smoothly connected with the concave cambered surface. According to the flow guiding ridge structure on the curve, the upstream face and the downstream face are independently designed, water currents are prevented from splashing due to the circular arc transition of the top portion of the upstream face, and then super-high water currents are further reduced; due to the fact that the arc surfaces at two ends of the upstream face of the flow guiding ridge are adopted to be respectively smoothly connected with the concave bank and the flow passing side, resistance of the water currents is reduced; due to the fact that the downstream face of the flow guiding ridge is formed by connection of the two sections of cambered surfaces, the water currents are enabled to smoothly transit to the bottom of a channel, and then the next flow guiding ridge is enabled to guide the flow conveniently, and damage caused by empty erosion is avoided. According to the flow guiding ridge structure on the curve, the super-high water currents can be fully reduced on the flood discharge curve, flow discharge is achieved smoothly, the water currents are enabled to be smooth, and the service life of a building is prolonged.
