Composite pier anti-collision device

The utility model relates to a composite type bridge pier anti-collision device which comprises an anti-collision truss arranged on the periphery of a bridge pier around the bridge pier, and the anti-collision truss is formed by splicing a plurality of truss sections left and right. The multiple composite anti-collision blocks are at least used for enabling the anti-collision truss to float on water, and the composite anti-collision blocks are detachably installed on the side, away from the pier, of the anti-collision truss; the damping blocks are installed on the side, facing the pier, of the anti-collision truss, and gaps exist between the damping blocks and the pier. According to the anti-collision device, multi-stage energy dissipation can be achieved, the anti-collision performance is higher than that of a common floating type anti-collision facility, cost can be saved in the manufacturing and installing process, later maintenance and replacement are convenient and fast, and the use cost of the anti-coll
