Fabricated anti-seismic bridge pier

Abstract

The invention discloses a fabricated anti-seismic bridge pier and belongs to the technical field of fabricated bridges. The fabricated anti-seismic bridge pier comprises a bridge pier body formed by assembling a plurality of segments from bottom to top in sequence. The side surface of the bridge pier body is provided with at least one vertical shock absorption beam. A damper is arranged between the shock absorption beams and the bridge pier body. Each shock absorption beam is fixedly connected with the segments through a plurality of branch beams arranged on one side of the shock absorption beam. The branch beams are arranged horizontally and are perpendicular to the shock absorption beams. When excited by the earthquake or other force in the horizontal direction, the segments are subjected to dislocation to generate outward acting force to the shock absorption beams through the branch beams, and the acting force is finally transmitted to the damper through the shock absorption beams, the fabricated anti-seismic bridge pier conducts shock absorption and energy dissipation through the damper to achieve the acting effect of eliminating shear force. The fabricated anti-seismic bridge piers can be mutually linked to conduct shock absorption and energy dissipation and is better in anti-seismic effect and longer in service life.

Description

technical field [0001] The invention relates to the technical field of assembled bridges, in particular to an assembled anti-seismic bridge pier. Background technique [0002] The pier is a sub-structure that supports the bridge span structure and transmits the constant section and vehicle live load to the foundation, and the abutment is set on the two lakes of the bridge. The piers are between the two abutments. The function of the bridge pier is to support the bridge span structure, and the surface abutment support not only plays the role of supporting the bridge span structure, but also connects with the embankment and prevents the embankment from slipping. [0003] Most of the existing prefabricated segmental assembly piers adopt the same prefabricated segmental assembly technology, the main shock absorption lies in the axial shock absorption, but the joints of the two assembly are mainly subjected to shear force, the bearing capacity is low, and there are often For th...

Problems solved by technology

[0003] Most of the existing prefabricated segmental assembly piers adopt the same prefabricated segmental assembly technology, the main shock absorption lies in the axial shock absorption, but the joints of the two assembly are mainly subjected to shear force, the bearing capacity is low, and there are often The problem of insufficient shear resistance and stability, in the prior art, there are few bridge piers that can provide damping force in the horizontal direction
