Abstract

The invention relates to an anti-overturning bridge pier supporting mechanism, in order to solves the problem that a single-column pier bridge easily causes disconnection of a supporting seat and even capsizing cases as adopting a single-point supporting beam in the prior art. The supporting mechanism comprises a pier column, carbon fiber cloth, a steel hoop component and two supporting seats, the steel hoop component comprises two horizontal support plates, two semicircular cylinders and four connectors, the two semicircular cylinders form a circular cylinder through the four connectors, one supporting seat is arranged on the upper surface of each horizontal support plate, the two horizontal support plates are arranged on the upper surface of the circular barrel horizontally and linearly, the carbon fiber cloth is wound at the top end of the pier column, and the circular cylinder is sleeved on the carbon fiber cloth on the outer side of the pier column. The anti-overturning bridge pier supporting mechanism is used in the field of bridge reinforcing.

Description

technical field [0001] The invention relates to a support mechanism for a bridge anti-overturning pier. Background technique [0002] In recent years, continuous girder bridges with single-column piers have been widely used as urban overpasses and viaducts, because of their simple and smooth shape, small building height, good visibility under the bridge, adaptable to many occasions, convenient construction and low engineering cost, etc. And has been greatly developed. However, since the single column pier bridge is supported by a single support seat in the transverse bridge direction, the overall lateral instability may occur under the eccentric load of the lane. In recent years, many overturning accidents have occurred, causing major economic losses and adverse social impacts . Accident investigation conclusions are mostly caused by overloading and overrunning of vehicles. The overturning and collapse of bridge structures occurs under the action of extreme events, which ...
