Pile foundation underpinning jacking structure and jacking method
The invention relates to the technical field of bridge engineering construction, in particular to a pile foundation underpinning jacking structure and a jacking method. The pile foundation underpinning and jacking structure is arranged between an existing bearing platform and a bridge and comprises an underpinning pile, an underpinning beam, a jacking piece and a lifting platform. The lower end of the underpinning pile is detachably connected with the existing bearing platform, and the underpinning beam is detachably connected with the upper end of the underpinning pile; the jacking part and the lifting platform are both arranged on the underpinning beam, the jacking part jacks the bridge, the lifting platform is used for supporting the bridge, and then the jacking part is released. The problems that an existing underpinning structure is high in cost, large in pollution, unstable in displacement control and the like are solved.
本发明涉及桥梁工程建设技术领域，尤其涉及一种桩基托换顶升结构及顶升方法。桩基托换顶升结构设置在既有承台和桥梁之间，包括：托换桩、托换梁、顶升件及升降平台；所述托换桩下端与所述既有承台可拆卸连接，所述托换梁与所述托换桩上端可拆卸连接；所述顶升件和升降平台均设置在所述托换梁上，所述顶升件顶升所述桥梁，利用所述升降平台支撑所述桥梁，然后释放所述顶升件。解决了现有托换结构成本高、污染大、位移控制不稳定等问题。
