Anti-overturning reinforcing device for single-column pier viaduct

Abstract

The invention discloses an anti-overturning reinforcing device for a single-column pier viaduct. The device comprises an original pile foundation, an original bearing platform, an original bridge pierand a bridge floor. A newly-built bearing platform is arranged on one side of the original bearing platform, a newly-built pile foundation is arranged below the newly-built bearing platform, a newly-built bridge pier is arranged on the newly-built bearing platform, and a top surface of the newly-built bridge pier makes contact with a bottom surface of one side of the bridge floor. The tops of thenewly-built bridge pier and the original bridge pier are connected with a horizontally-arranged steel beam, a fulcrum is arranged at the end of the other side of the steel beam, and the top surface of the fulcrum makes contact with the bottom surface of the other side of the bridge floor. When the bridge floor on one side of the newly-built bridge pier has an overturning trend, the newly-built bridge pier and the original bridge pier jointly support the bridge floor and bear vertically downward pressure; and when the bridge floor on the other side of the newly-built bridge pier has the overturning trend, the fulcrum on the steel beam and the original bridge pier jointly support the bridge floor, the original bridge pier is subjected to vertically downward pressure, and the newly-built bridge pier is subjected to a vertically upward pulling force. The device has a prevention effect on overturning of the bridge in two directions.

Description

technical field [0001] The invention relates to the field of bridge engineering in the field of engineering construction, in particular to an anti-overturning reinforcing device for a viaduct with a single column pier. Background technique [0002] Due to the advantages of reducing land occupation, increasing vision and beautiful bridge shape, single-pillar bridges are widely used in urban viaducts in my country. However, the anti-overturning ability of the single-pillar bridge is poor, and it is easy to induce overturning and collapse when the truck is overloaded. [0003] It can be seen that with the development of social economy, the traffic volume is increasing day by day, especially the occasional serious overloaded trucks go on the bridge illegally (some overloaded up to more than 200%), which leads to the existence of greater safety hazards in the single-pillar pier viaduct. It is necessary to strengthen the existing single-pillar viaducts in some key road se...

Problems solved by technology

However, the anti-overturning ability of single-pillar bridges is poor, and it is easy to induce overturning and collapse when the truck is overloaded.

[0003] It can be seen that with the development of social economy, the traffic volume is increasing day by day, especially the occasional serious overloaded trucks go on the bridge in violation of regulations (some overloaded as high as 200%), resulting in a greater safety hazard in the single-pillar pier viaduct
