Bridge pier anti-collision system

The utility model relates to a bridge pier anti-collision system which comprises a first anti-collision part and a second anti-collision part. The first anti-collision part comprises at least two anti-collision piers arranged on the periphery of the pier, supporting parts are arranged at the bottoms of the anti-collision piers and support the anti-collision piers, and the second anti-collision part is arranged on the periphery of the first anti-collision part in a surrounding mode; the second anti-collision part comprises a suspension type box body which is suspended on the water surface. The combination of the first anti-collision part and the second anti-collision part enables the bridge pier anti-collision system to block and eliminate the vast majority of impact force of an impact object, residual energy generated after the impact object collides with the second anti-collision part is completely borne by the first anti-collision part, the bridge pier almost does not bear the impact force, and the bridge p
