An anti-overturning reinforcing device for a single-column pier bridge relates to the technical field of bridge reinforcement and comprises a bridge girder and a single-column pier, the single-column pier is arranged at the bottom of the bridge girder and used for supporting the bridge girder, and the anti-overturning reinforcing device further comprises a reinforcing assembly and a bearing part. The bearing piece is located on the upper portion of the reinforcing assembly and connected with the reinforcing assembly through a hydraulic cylinder. The reinforcing assembly comprises a steel hoop hooped on the lower portion of the single-column pier and inhaul cables located on the two sides of the steel hoop, and the two ends of the inhaul cables are connected with the steel hoop and the bridge girder through hinge seats respectively to form an integral structure. The tension performance of the inhaul cable is ingeniously utilized, extra constraint is provided for the left side and the right side of the single fulcrum position of the main beam, the stress state of an upper structure is effectively improved, the anti-overturning stability performance of the bridge is improved, and overturning accidents are effectively avoided.

一种用于独柱墩桥梁的抗倾覆加固装置，涉及桥梁加固技术领域，包括桥梁主梁和独柱墩，所述独柱墩设置设于桥梁主梁的底部并用于支撑桥梁主梁，还包括加固组件和承载件，所述承载件位于加固组件的上部、且其与加固组件之间通过液压缸相连接；所述加固组件包括箍设在独柱墩下部的钢抱箍，位于钢抱箍两侧的拉索，所述拉索的两端分别通过铰接座与钢抱箍及桥梁主梁相连接，并使其形成整体结构；其巧妙利用拉索的受拉性能，在主梁单支点位置左右两侧提供额外约束，有效改善上部结构受力状态，增加桥梁抗倾覆稳定性能，有效避免倾覆事故的发生。
