Self-resetting fabricated precast concrete arch bridge
The invention discloses a self-resetting fabricated precast concrete arch bridge. The arch bridge comprises at least two arch beam assemblies and a plurality of arch bridge plates erected between thearch beam assemblies at intervals. Each arch beam assembly is of a prefabricated reinforced concrete structure and comprises a plurality of middle prefabricated sections and end prefabricated sectionsarranged at the two ends of the middle prefabricated sections, the prefabricated sections are tied through prestressed tendons, and steel plate sheaths are arranged at the ends of the prefabricated sections. According to the arch bridge structure, self-resetting is achieved under the load action of earthquakes or vehicles and the like, the construction efficiency and the construction quality aregreatly improved, and the anti-seismic property is excellent.
一种自复位装配式预制混凝土拱桥，包括至少两个拱梁组件和多个间隔搭设在拱梁组件之间的拱桥板，所述拱梁组件采用预制钢筋混凝土结构，包括多个中部预制段和设置在两端的端部预制段，各预制段之间通过预应力筋拉结，同时在各预制段的端部设置钢板护套。本发明提出的上述拱桥结构，在地震或车辆等荷载作用下实现自复位，大大提高了施工效率和施工质量，抗震性能优越。
