Built-in stable support reinforced single-pier bridge structure

Abstract

The invention discloses a built-in stable support reinforced single-pier bridge structure. The structure comprises a box girder, a single-column pier, stabilizing supports, a newly-added support, an anchoring pull rod and built-in supports, wherein the paired stabilizing supports are arranged on two side surfaces of the single-column pier in the transverse bridge direction, a plurality of pairs ofbuilt-in supports are symmetrically arranged on two side walls of the single-column pier in the transverse bridge direction, a bottom end of a vertical rod of the stabilizing supports is connected with the built-in supports in a supporting mode, vertical rods are arranged in the side wall direction of the single-column pier, at least one row of anchoring pull rods penetrate through the cross section of the single-column pier to oppositely pull and fix the vertical rods of the stabilizing supports in the transverse bridge direction, and the newly-added support is directly or indirectly supported and fixed to the top of the stabilizing supports through the horizontal distribution beam and is tightly supported on a bottom surface of the box girder. The reinforced structure is simple in system, small in number of parts, reasonable and clear in stress, easy to standardize and universal in applicability.

Description

technical field [0001] The invention relates to a bridge reinforcement structure, in particular to a single column pier bridge structure reinforced by an embedded stable support, which belongs to the technical field of bridges. Background technique [0002] Single-column piers belong to the substructure of bridges, and are commonly found in flyover bridges, overpass bridges and ramp bridges for expressway interchanges on urban roads. Due to the heavy urban traffic and limited land acquisition for construction in and around the city, the pier is often required to fall within a limited range during construction. The single-pillar bridge has many advantages such as beautiful form and small footprint, making it an important part of modern bridge engineering. It occupies an important position in construction, but due to its poor lateral stability and poor torsion resistance, there are great safety hazards in the process of operation, especially under the action of eccentric vehic...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned anti-overturning technology of single-pillar pier bridges has a complex reinforcement structure system, limited bearing capacity of hoops, and many parts involved in processing, and the components are difficult to standardize, so it is difficult to be generally applicable to the reinforcement of single-pillar pier bridges
