FRP-steel-concrete combined pier and preparation method thereof
The invention provides an FRP pipe-steel-concrete combined pier. A pier body of the FRP pipe-steel-concrete combined pier is formed by combining an FRP pipe on the outer side, a steel pipe on the inner side and a dry plate and pouring concrete. The FRP pipe on the outer side is good in corrosion resistance, and the situation that the FRP pipe and concrete in the FRP pipe are corroded can be effectively avoided; the strength, the bearing capacity and the durability of the pier body can be effectively enhanced through the internal steel pipes and steel plates; no concrete is poured in the steel pipe, so that the pier body has good ductility; meanwhile, after the pier is maintained, replaced or abandoned in the later period, the FRP pipe on the outer layer is easy to dismantle, concrete can fall off conveniently, and steel can be recycled.
本发明提供了一种FRP管‑钢材‑混凝土组合桥墩，其墩身由外侧的FRP管及内侧的钢管和干板组合并浇筑混凝土而成；外侧的FRP管的耐腐蚀性能好，可以有效避免自身以及内部的混凝土被腐蚀的情况；内部的钢管钢板可有效加强墩身的强度、承载力和耐久性；钢管内不浇筑混凝土是墩身具有良好的延性；同时在后期桥墩维护更换或废弃后，外层的FRP管易拆除便于将混凝土脱落，将钢材进行回收。
