Single-column pier bridge anti-overturning lifting device applied under extreme eccentric load
The invention discloses a single-column pier bridge anti-overturning lifting device applied under extreme eccentric load, which belongs to the technical field of bridge overturning resistance and comprises limiting support components symmetrically arranged on two sides of a bridge pier and steel strands on two sides of a box girder. One end of the steel strand is fixed to the corner of a box girder flange plate and a web, and the other end of the steel strand is connected with the limiting supporting assembly which is arranged on the top of a pier. When one side of the box girder is subjected to extreme vehicle unbalance loading and rotates, the steel strand is used for generating pulling force on the other side of the girder body, and anti-overturning moment is formed; when the rotation angle of the bridge body is too large, the limiting supporting assemblies on the two sides are clamped, at the moment, the supporting counter force transmitted by the supporting device and acting on the bridge pier and the pulling force of the steel strand jointly form an anti-overturning moment, and the bridge can be effectively prevented from overturning. The structure is simple and compact, the cost is low, secondary damage to the structure is avoided in the construction process, normal traffic under the bridge can be guaranteed, the anti-overturning force of the bridge is improved, and the single-column pier bridge is effectively prevented from overturning.
本发明公开了一种应用于极端偏心荷载下的独柱墩桥梁抗倾覆提升装置，属于桥梁抗倾覆技术领域，包括对称设于桥墩两侧的限位支撑组件及箱梁两侧的钢绞线，钢绞线一端固定于箱梁翼缘板与腹板的拐角处、另一端与限位支撑组件相连，限位支撑组件设于桥墩顶部。当箱梁一侧受到极端车辆偏载发生转动时，利用钢绞线对梁体另一侧产生拉力，形成抗倾覆力矩；当梁体转动角度过大，两侧限位支撑组件卡死，此时由支撑装置传递并作用在桥墩上的支撑反力、钢绞线拉力共同形成抗倾覆力矩，能有效防止桥梁倾覆。本发明结构简单紧凑、成本低廉，施工过程中不会产生结构次病害，采用本发明能够保证桥下正常交通，提高桥梁的抗倾覆力，有效防止独柱墩桥梁发生倾覆。
