Bridge pier anti-overturning structure

Abstract

The invention discloses a bridge pier anti-overturning structure which comprises a mounting bottom plate, and the mounting bottom plate is fixedly connected with a platform body through bolts; inserting holes corresponding to a bridge support body are matched with connecting bosses, so that the bridge support body is installed in a limited mode, the bridge support body is installed conveniently inan inserted mode from top to bottom, and it is guaranteed that the bridge support body is installed in place; a steel ball block is arranged and supports the bridge support body through a trapezoidalblock and a top plate; when eccentric overload suddenly occurs, the bridge support generates micro-deflection deformation under the condition of sudden overload, and at the moment, the bridge supportperforms micro-rotation along with the top plate and the trapezoidal block through the steel ball block according to the deflection direction, so that the micro-deformation caused by overload is partially counteracted; hard pressure on the bridge support due to overload is prevented, meanwhile, more time is bought for pressure transfer on the surface of the bridge, and the probability that the bridge overturns is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridges, in particular to a bridge pier anti-overturning structure. Background technique [0002] Bridges refer to buildings built for roads to cross natural or artificial obstacles. Refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; the auxiliary structures refer to the bridge head abutment, conical slope protection, revetment, diversion works, etc.; bridges are divided according to the structural system, including girder bridges, arch bridges, There are four basic systems of rigid frame bridge and suspension cable bearing (suspension bridge, cable-stayed bridge). [0003] The pier is mainly composed of a top cap and the pier body; the abutment is mainly composed of the top cap and the abutment body; Therefore, the top hat should be constructed with high-strength materials, generally not less than 200-grade reinforced concrete, and the th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a bridge pier anti-overturning structure to solve the above-mentioned background technology in order to uniformly disperse the pressure of the bridge, it is necessary to ensure that the bridge is properly docked, and at the same time prevent The problem of overturning phenomenon when suddenly subjected to eccentric overload
