Pier protection structure, mounting method and pier structure
The invention discloses a bridge pier protection structure, an installation method and a bridge pier structure. The bridge pier protection structure comprises a plurality of pipe fittings which are evenly arranged in the circumferential direction of a bridge pier at intervals; the UHPC layer is arranged around the peripheries of the pipe fittings, a gap exists between the UHPC layer and the pier, the UHPC layer comprises a plurality of UHPC components, the two ends of each UHPC component are provided with arc-shaped faces respectively, the UHPC components are sequentially spliced, the adjacent UHPC components are spliced to form arc-shaped grooves used for limiting the pipe fittings, and the pipe fittings are rotationally arranged in the arc-shaped grooves respectively. The periphery of the UHPC layer is wrapped with the anti-corrosion sleeve, so that the UHPC layer, the pipe fitting and the pier are sequentially and tightly connected in an abutting mode, and the UHPC layer and the anti-corrosion sleeve can rotate relative to the pier. The design of imitating a bearing is adopted, the anti-corrosion sleeve and the UHPC layer are equivalent to a bearing outer ring, the pipe fitting is equivalent to a bearing ball, the bridge pier is equivalent to a bearing inner ring, impact energy is consumed in a rotating and mutual friction generating mode, and the corrosion resistance and the impact resistance of the bridge pier are improved through the combination of the anti-corrosion material and the UHPC material.
本申请公开了一种桥墩防护结构、安装方法及桥墩结构，桥墩防护结构包括多个管件，沿桥墩的周向均匀地间隔设置；UHPC层围绕各管件的外周设置，UHPC层与桥墩之间存在间隔，UHPC层包括多个UHPC构件，UHPC构件的两端分别设有弧形面，各UHPC构件依次拼接，相邻的UHPC构件拼接后形成用于限位管件的弧形槽，各管件分别可转动地设置在各弧形槽内；防腐蚀套筒包裹在UHPC层外周，使UHPC层、管件和桥墩依次地紧密抵接，且UHPC层和防腐蚀套筒可与桥墩之间发生相对转动。采用仿轴承的设计，防腐蚀套筒和UHPC层相当于轴承外圈，管件相当于轴承滚珠，桥墩相当于轴承内圈，通过转动和相互产生摩擦的方式消耗冲击能，防腐蚀和UHPC材料相结合提高桥墩的耐腐蚀性和抗冲击能力。
