Anti-collision and anti-seismic integrated replaceable combined pier

Abstract

The invention relates to the field of piers and particularly discloses an anti-collision and anti-seismic integrated replaceable combined pier. The combined pier comprises a lower pier structure, an upper pier structure and an anti-collision and anti-seismic assembly, wherein the lower bridge pier structure and the upper bridge pier structure are detachably connected; the anti-collision and anti-seismic assembly is installed on the lower pier structure, is sequentially provided with an anti-collision layer, an anti-seismic layer and a rubber cylinder from inside to outside and is for collision prevention and seismic resistance of the pier. The anti-collision layer is formed by arranging transverse corrugated plates which are uniformly arranged on the lower pier; the anti-seismic layer is formed by arranging vertical corrugated plates; the transverse corrugated plates are connected with the vertical corrugated plates; the transverse corrugated plate blocks are sleeved with the rubber cylinders, and the lower pier is wrapped with the rubber cylinders. The combined pier has anti-collision and anti-seismic functions and is convenient to replace and easy to maintain.

Description

technical field [0001] The invention relates to the field of bridge piers, in particular to an anti-collision and anti-seismic integrated replaceable composite bridge piers. Background technique [0002] Bridges are important hubs of traffic lifelines. Once a bridge is damaged during an earthquake, it is easy to cause traffic interruption, resulting in the failure of rescuers to arrive in time, which in turn causes immeasurable casualties and economic losses. As the main components of bridges, bridge piers play a vital role in the overall seismic performance of bridges. The pier is used to support the main body of the bridge, the upper part of the pier is connected with the main body of the bridge, and the lower part of the pier is fixed on the ground. When an earthquake occurs, for traditional reinforced concrete piers, the lower part of the pier is usually damaged more frequently, so that the lower part of the pier is damaged first, and the degree of damage to the lower p...
