An anti-collision composite bridge pier

Abstract

The invention discloses an anti-collision combined bridge pier, comprising a pier body body, a plurality of guide grooves are evenly arranged on the surface of the pier body body located in the water body, concave steel is arranged in the guide grooves, and the outer surface of the pier body body is There is also a ring-shaped floating sleeve, and a plurality of floating guide blocks are arranged on the inner wall of the ring-shaped floating sleeve. The floating guide blocks are arranged in the corresponding concave steel. There are also multiple buffer mechanisms evenly arranged on the outer periphery. The buffer mechanism includes two elastic steel plates, a sliding mounting plate and an anti-collision rubber block. A pulley is arranged on one side of the sliding mounting plate, and the pulley is arranged in a C-shaped channel. One side surface is connected with the anti-collision rubber block, and two elastic steel plates are arranged between the sliding installation plate and the anti-collision rubber block, and the two elastic steel plates are symmetrical and curved. The invention has strong impact bearing capacity and can effectively protect bridge piers from damage.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an anti-collision combined bridge pier. Background technique [0002] Bridge pier generally refers to the intermediate supporting structure of a multi-span bridge, which bears not only the load of the superstructure, but also the pressure of flowing water, the wind force above the water surface, the possible ice load, and the impact force of ships, rafts or drifting objects. [0003] Therefore, anti-collision is extremely important. Existing bridge piers generally use their own strength for anti-collision, which can easily lead to damage to the piers, which generally cannot be repaired after damage, and affect the use of the bridge body. And there are also some methods of wrapping anti-collision strips or anti-collision blocks, which have limited anti-collision capacity and cannot meet the impact of larger objects such as ships.

Problems solved by technology

[0003] Therefore, anti-collision is extremely important. Existing bridge piers generally use their own strength for anti-collision, which can easily lead to damage to the pier. After damage, it is generally impossible to repair and affect the use of the bridge body.

There are also some methods of wrapping anti-collision strips or anti-collision blocks, which have limited anti-collision bearing capacity and cannot meet the impact of larger objects such as ships.
