Abstract

The invention discloses an anti-overturning reinforcing device for a single-column pier bridge, which comprises a single-column pier, a widening structure is arranged on the upper end of the single-column pier, and a support is arranged on the top of the widening structure. The invention provides an anti-overturning reinforcement device for a single-column pier bridge. When the space under the bridge is limited or the conditions are not allowed, a steel cover girder is added to the width of a single-column pier in the middle of a continuous box girder, and the steel cover girder is changed. Set up double supports, through the setting of double supports, the influence of unbalanced load is reduced for straight bridges, and the torsional moment can be effectively improved for curved and inclined bridges, the force of bridge devices is improved, and 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...
