Cable-stayed single-pier anti-overturning device
The invention relates to the technical field of single-pier bridges, in particular to a cable-stayed single-pier anti-overturning device which comprises a fixing base, a plug pin and steel strands. The fixing base is fixed to the pier body in a wrapping mode, and when the fixing base is fixed, a certain gap is reserved between the inner wall of the fixing base and the pier body. The plug pin has awedge-shaped cross section and is fixed on the pier body, and the bottom of the plug pin is clamped in a gap between the fixing base and the pier body; the steel strands are symmetrically arranged ontwo sides of the pier body, one ends are connected with the fixing base, and the other ends are connected with two wings of the bridge body. The fixing seat and the steel strand are arranged, the steel strand is connected with two wings of the bridge body, the inclined load of the bridge body is increased, when the bridge body inclines, due to the arrangement of the plug pin, the bridge body is prevented from overturning due to further movement of the fixing base, the safety performance of the single-column pier bridge is improved, and due to the fact that the fixing base, the plug pin and the steel strands are easy and convenient to install, occupied equipment is little and influence on traffic is small.
本发明涉及独柱墩桥梁技术领域，尤其涉及一种斜拉式独柱墩抗倾覆装置，包括：固定座、插销和钢绞线；固定座包绕固定在墩身上，且固定座在固定时，其内壁与墩身之间留有一定间隙；插销的截面呈楔形固定墩身上，且插销的底部卡设于固定座与墩身之间的间隙中；钢绞线对称设置于墩身两侧，且一端与固定座连接，另一端与桥体的两翼连接。本发明通过固定座和钢绞线的设置，钢绞线与桥体两翼连接，提升了桥体的倾斜的载重，且在桥体发生倾斜时，由于插销的设置，防止了固定座的进一步移动造成的桥体倾覆，提高了独柱桥墩桥梁的安全性能，而且由于固定座和插销以及钢绞线的安装简便，占用设备少，对交通的影响较小。
