FRP-concrete combined bridge structure and construction method thereof
The invention discloses an FRP-concrete combined bridge structure. The structure comprises a bridge deck slab, a beam body, a combined pier column and a combined foundation which are sequentially connected from top to bottom. The bridge deck slab comprises an FRP plate and a concrete structure layer which are connected, the beam body comprises a cross beam and a longitudinal beam which are connected, and reinforcing ribs are arranged in the cross beam and the longitudinal beam; the combined pier column comprises a core column, an FRP pipe and an anti-scouring structure layer which are connected, the FRP pipe is arranged outside the core column, and the anti-scouring structure layer is arranged outside the FRP pipe; the combined foundation comprises a bearing platform and a pile foundationwhich are connected, and FRP ribs are arranged in the bearing platform and the pile foundation; and the FRP plate, the reinforcing ribs, the FRP pipe and the FRP ribs are all made of fiber reinforcedcomposite materials. The invention further provides a construction method of the FRP-concrete combined bridge structure, the fiber reinforced composite material is utilized, the bridge structure has good durability, a using amount of steel bars and formworks is reduced, a construction speed is increased, the anti-scouring structure layer is arranged in the combined pier column, and durability of the component is further improved.
本发明公开一种FRP‑混凝土组合桥梁结构，包括自顶至底依次相连的桥面板、梁体、组合墩柱和组合基础，桥面板包括相连的FRP板和混凝土结构层，梁体包括相连的横梁和纵梁，横梁和纵梁内均设置加强筋；组合墩柱包括相连的芯柱、FRP管和防冲刷结构层，FRP管设置于芯柱的外部，防冲刷结构层设置于FRP管的外部；组合基础包括相连的承台和桩基，承台和桩基内均设置FRP筋；FRP板、加强筋、FRP管、FRP筋均由纤维增强复合材料制成。本发明还提供一种FRP‑混凝土组合桥梁结构的施工方法，利用了纤维增强复合材料，使桥梁结构具有较好的耐久性，减少了钢筋用量和模板用量，提高了施工速度，在组合墩柱中设置了防冲刷结构层，进一步提高了构件的耐久性。
