Abstract

The invention discloses an anti-overturning reinforcing device of a single-column-pier bridge. The anti-overturning reinforcing device comprises a single-column pier. A widening structure is arranged at the upper end of the single-column pier. A support is arranged at the top end of the widening structure. The anti-overturning reinforcing device of the single-column-pier bridge provided by the invention has the advantages that since a steel cover beam is additionally arranged on a certain middle single-column pier of a continuous box beam along the width direction and dual supports are arranged on the steel cover beam under the situation that the space under the bridge is limited or conditions are not allowed, the influence of unbalanced loads on straight bridges is reduced, the torque and the moment can be effectively improved for curved bridges and skew bridges, the stress of bridge devices is improved and the potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the pier column design of the substructure of a single-pillar pier bridge, in particular to an anti-overturning reinforcement device for a single-pillar pier bridge. Background technique [0002] At present, continuous box girder bridges with single-pillar piers are widely used in highway bridges because of their advantages such as saving land, visual transparency, smooth lines, and beautiful appearance. And it also has the characteristics of simple and smooth appearance, occupying less space under the bridge, etc., and is equipped with a light and beautiful overall bridge, which is widely used in urban bridges and high-speed interchange ramps. [0003] However, with the development of my country's economy, the traffic flow and vehicle load continue to increase, and the unbalanced load of overweight vehicles has led to a number of overturning and collapse accidents of single-pillar pier box girder bridges in China in recent yea...
