Synchronous jacking method for multi-span continuous bridge
The invention discloses a synchronous jacking method for a multi-span continuous bridge, which comprises a jacking method, and the jacking method comprises a foundation construction stage, a jacking equipment installation and debugging stage, a jacking adjustment and acceptance stage, a jacking construction stage and a load holding stage. In the foundation construction stage, jacking equipment installation is organized, and supporting protection is installed outside the jacking equipment; in the installation and debugging stage of the jacking equipment, after the jacking equipment is in place, joint debugging and joint testing of the jacking equipment and a main control center are carried out, and preparation is made for jacking load testing; in the jacking adjustment acceptance inspection stage, the jacking equipment is subjected to self-inspection, and after the jacking equipment is qualified, the jacking equipment is accepted and prepared for jacking; relates to the technical field of multi-span continuous bridge jacking. The long-stroke hydraulic jack is adopted for jacking construction, the jacking height of each jacking cycle is increased, the jacking cycle frequency and the supporting heightening operation frequency are reduced, the duration of the jacking process is shortened, and the exposure time of the upper structure in the suspension state is shortened.
本发明公开了一种多跨连续桥梁的同步顶升方法，包括顶升方法，所述顶升方法包括基础施工阶段、顶升设备安装调试阶段、顶升调节验收阶段、顶升施工阶段和持荷阶段；在所述基础施工阶段中，组织进行顶升设备安装并在所述顶升设备外部安装支撑保护；在所述顶升设备安装调试阶段中，当所述顶升设备就位后进行顶升设备与主控中心的联调联试，为起顶负载测试做准备；在所述顶升调节验收阶段中，对所述顶升设备进行自检、合格后验收顶升设备并预备顶升；涉及多跨连续桥梁顶升技术领域。本发明采用长行程液压千斤顶进行顶升施工，加大每个顶升循环的顶升高度，减少顶升循环次数和支撑接高操作次数，缩短顶升过程的时长，减少上部结构悬浮状态暴露时间。
