Anti-overturning self-balancing reinforcing device for single-column pier bridge
The invention discloses an anti-overturning self-balancing reinforcing device for a single-column pier bridge, which belongs to the technical field of bridge reinforcement and comprises a steel lantern ring and a plurality of steel strands, the plurality of steel strands are symmetrically arranged along the outer walls of the two sides of a box girder respectively, one end of each steel strand is fixed at the corner of a flange plate and a web plate of the box girder, and the other end of each steel strand is fixed at the bottom of a steel strut at the edge of the steel lantern ring. The two fixed ends of the same steel strand are symmetrically arranged on the two sides of the bridge pier, and the steel sleeve rings are arranged on the bridge pier in a sleeving mode; the direction of the steel strand is changed by means of a redirection assembly at the bottom edge of the box girder. The overturning force borne by the box girder during rotation can be converted into the pulling force of the steel strand to the flange plate of the box girder on the other side, when the rotation of the box girder is further increased, the steel supporting column can be clamped on the steel lantern ring to provide supporting force for the box girder, and overturning of a high-pier single-column pier bridge can be effectively prevented; meanwhile, the structure is simple and compact, construction is convenient, the manufacturing cost is low, normal traffic under the bridge cannot be affected in the construction process, and the space under the bridge cannot be occupied.
本发明公开了一种独柱墩桥梁抗倾覆自平衡加固装置，属于桥梁加固技术领域，包括钢套环及多根钢绞线，多根钢绞线分别沿箱梁两侧外壁对称设置，钢绞线一端固定于箱梁翼缘板与腹板的拐角处、另一端固定于钢套环边缘的钢支柱底部，同一根钢绞线的两个固定端对称设置于桥墩的两侧，钢套环套于桥墩上；钢绞线借助箱梁底部边缘的改向组件来改变方向。本发明能够将箱梁转动时受到的倾覆力转换为钢绞线对另一侧箱梁翼缘板的拉力，当箱梁转动进一步增大时钢支柱会卡死在钢套环上对箱梁提供支持力，能有效防止高墩独柱墩桥梁发生倾覆，同时本发明结构简单紧凑、施工方便、制作成本低廉，在施工过程中不会影响桥下正常交通，也不会占用桥下空间。
