Swivel curved bridge structure and curved bridge eccentric swivel construction method
The invention discloses a swivel curved bridge structure and a curved bridge eccentric swivel construction method.The swivel curved bridge structure comprises a pier, a curved beam body is arranged at the top end of the pier, a rotating bearing platform is arranged at the bottom end of the pier, the rotating bearing platform comprises an upper bearing platform, a lower bearing platform and a spherical hinge structure, athe upper bearing platform is rotationally arranged on the lower bearing platform through the spherical hinge structure, a plurality of auxiliary supporting legs and an active supporting leg are arranged at the bottom of the upper bearing platform, the auxiliary supporting legs and the active supporting leg are annularly and uniformly distributed at the bottom of the upper bearing platform, and the active supporting leg is located on the inner arc side of the transverse axis of the curved beam body; each active supporting leg comprises a pressure sensor arranged at the bottom of the upper bearing platform and a sliding block connected to the bottom of the pressure sensor. The pressure-measurable sliding block serves as an active supporting leg and can be used for swivel construction of a curve bridge with large transverse eccentricity. The unstable state of only spherical hinge supporting is avoided when the rotating body of the curved bridge rotates, the stability of the rotating body in the rotating process is improved, the rotating process is more controllable, the construction precision is high, and the stability is better.
本发明公开了一种转体曲线桥构造及曲线桥偏心转体施工方法，包括桥墩，桥墩的顶端设有曲线梁体，桥墩的底端设有转动承台，转动承台包括上承台、下承台及球铰结构，上承台通过球铰结构转动设置在下承台上，上承台的底部设有多个辅助支撑脚和一个主动支撑脚，辅助支撑脚和主动支撑脚呈环形均布在上承台的底部，且主动支撑脚位于曲线梁体的横轴线的内弧侧，主动支撑脚包括设置在上承台底部的压力传感器和连接在压力传感器底部的滑块。可测压力滑块作为主动支撑脚，可用于具有较大横向偏心的曲线桥梁的转体施工。使曲线桥的转动体在转动时避免了仅球铰支撑的不稳定状态，增加了转动过程中转动体的稳定性，转体过程更加可控、施工精度高、稳定性更好。
