Active adjustment anti-overturning device for single-column pier bridge under action of extreme unbalance loading
The invention discloses a single-column pier bridge active adjustment anti-overturning device under the extreme unbalance loading effect, and belongs to the technical field of bridge reinforcement, the single-column pier bridge active adjustment anti-overturning device comprises a hoop and a joist which are arranged on the top of a single-column pier in a sleeving mode, the joist is arranged below the hoop, and two sets of anti-overturning mechanisms arranged on the two sides of the hoop are arranged on the top face of the joist; the two ends of the steel strand of the left anti-overturning mechanism are connected with the right side of the bottom of the box girder, the two ends of the steel strand of the right anti-overturning mechanism are connected with the left side of the bottom of the box girder, and the box girder is prevented from rotating through the two anti-overturning mechanisms so as to resist bridge overturning caused by unbalance loading. When the unbalance loading of a vehicle on one side of the box girder is larger than the designed load, the box girder on the side rotates, and the box girder is prevented from continuously rotating to resist bridge overturning caused by the unbalance loading through the pulling force applied to the bottom of the box girder on the other side by the steel strand. The device does not occupy too much space under the bridge, is convenient to mount and low in manufacturing cost, and adopts the steel strands to improve the stability and anti-overturning performance of the single-column pier bridge structure.
本发明公开了一种极端偏载作用下的独柱墩桥梁主动调节抗倾覆装置，属于桥梁加固技术领域，包括套于独柱墩顶部的抱箍及托梁，托梁设于抱箍下方，托梁顶面上设有两组置于抱箍两侧的抗倾覆机构，左侧抗倾覆机构的钢绞线两端与箱梁底部右侧相连，右侧抗倾覆机构的钢绞线两端与箱梁底部左侧相连，通过两组抗倾覆机构来阻止箱梁发生转动以抵抗偏载引起的桥梁倾覆。当箱梁一侧车辆偏载大于设计荷载时，该侧箱梁发生转动，利用钢绞线对另一侧箱梁底部施加的拉力，阻止箱梁继续发生转动来抵抗偏载引起的桥梁倾覆。本发明不会过多占用桥下空间，安装方便，制作成本低，采用钢绞线提高独柱墩桥梁结构的稳定性及抗倾覆性能。
