Light anti-collision structure of concrete river-crossing pier and construction method

The invention discloses a concrete river-crossing pier light-weight anti-collision structure and a construction method, the concrete river-crossing pier light-weight anti-collision structure comprises an anti-collision structure connected between two adjacent piers, each pier is divided into a pier base and a bridge column at the top of the pier base, the anti-collision structure comprises an anti-collision net, the anti-collision net is connected between the adjacent bridge columns, and the middle part of the anti-collision net sinks to the water surface; when the middle part of the anti-collision net swings towards one side, the anti-collision net does not make contact with the bridge pier base on the side, and the anti-collision structure is installed at the top of the side, close to the side, of the bridge pier base; the invention relates to the technical field of bridge engineering. According to the concrete river-crossing pier light-weight anti-collision structure and the construction method, the struct
