Abstract
The utility model discloses a bridge pier anti-collision buffering device, which comprises a mounting base. The cross section of the mounting base is a triangular prismatic body; the mounting base is provided with a mounting surface I, a mounting surface II and a fixed surface; anti-collision baffle plates are respectively arranged on the mounting surface I and the mounting surface II; and buffering springs are used for connecting the anti-collision baffle plates and the mounting surfaces. The bridge pier anti-collision buffering device adopting spring shock absorption principle is capable of absorbing collision force of vessels through strain of the springs when the vessels collide to the surfaces of the buffering device, thereby avoiding damage to a bridge pier. Simultaneously, damage of the vessels is relieved or avoided to a certain degree. Matching the arrangement of the buffering springs, the bridge pier anti-collision buffering device further adopts various accessory methods, thereby achieving better protective effect. The bridge pier anti-collision buffering device has excellent social value and economic value.
