Rigid-flexible combined pier anti-collision reinforcing device and reinforcing method
The invention provides a rigid-flexible combined bridge pier anti-collision reinforcing device and a reinforcing method. The rigid-flexible combined bridge pier anti-collision reinforcing device comprises embedded steel bar UHPC (Ultra High Performance Concrete) poured on the outer side of a bridge pier; the floating steel jacket box is arranged on the outer side of the pier in a sleeving mode, a gap is formed between the floating steel jacket box and the embedded steel bar UHPC concrete surface layer, and the floating steel jacket box can rotate freely and float up and down in the height direction of the pier. Multi-stage anti-collision protection is adopted, rigidity and flexibility are combined, the ship collision force is reduced, the bridge pier is directly reinforced, and when the ship collision force is not large, only the floating steel jacket box on the outermost side is damaged; due to the rotatable characteristic of the floating steel jacket box, the device can absorb a larger level of ship impact force, and extrusion crushing occurs between the floating steel jacket box and the embedded UHPC concrete through rotation; the embedded steel bars are arranged in the embedded steel bar UHPC concrete, so that the anti-collision capability of the device is further enhanced. According to the three-level anti-collision capacity, the bridge pier anti-collision device has the excellent anti-collision performance, can be applied to actual bridge pier anti-collision, and can cope with the ship collision problem with different collision force.
本发明提供了一种刚柔结合式桥墩防撞加固装置及加固方法，包括植筋UHPC混凝土，浇注在桥墩的外侧；浮动钢套箱套设在桥墩的外侧，且浮动钢套箱与植筋UHPC混凝土表层之间具有间隙，浮动钢套箱可自由转动并沿桥墩的高度方向上下浮动。本发明采用多级防撞保护，刚柔结合，既降低了船撞力，又对桥墩进行了直接加固，当所受船撞力不是很大时，仅破坏最外侧的浮动钢套箱；浮动钢套箱可转动的特性使得装置能够吸收更大一级的船撞力，转动使得浮动钢套箱和植筋UHPC混凝土之间发生挤压破碎；植筋UHPC混凝土内部的植筋，进一步加强了装置的防撞能力。综上三级防撞能力，本发明具有优良的防撞性能，可应用于实际桥墩防撞之中，可以应对不同撞击力的船撞问题。
