Anti-overturning reinforcing device for single-column pier viaduct
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.
本发明公开了一种独柱墩高架桥的防倾覆加固装置，包括有原桩基、原承台、原桥墩和桥面，原承台的一侧设置有新建承台，新建承台的下方设置有新建桩基，新建承台上设置有新建桥墩，新建桥墩的顶面与桥面的一侧底面相互接触；新建桥墩和原桥墩的顶部连接有呈水平设置的钢梁，钢梁的另一侧端部设置有支点，支点的顶面与桥面的另一侧底面相互接触。当新建桥墩一侧的桥面具有倾覆趋势时，新建桥墩和原桥墩共同支撑桥面且均受到竖直向下的压力；当新建桥墩的另一侧桥面具有倾覆趋势时，钢梁上的支点和原桥墩共同支撑桥面，原桥墩受到竖直向下的压力，而新建桥墩受到竖直向上的拔力；本发明对桥梁两个方向的倾覆均具有阻止效果。
