High-speed rail cast-in-place box girder aerial overall displacement method
The invention relates to the technical field of bridges, in particular to a high-speed rail cast-in-place box girder aerial overall displacement method which comprises the steps that protection cushion blocks are installed in the box girder jacking process; a transverse moving walking system is installed at the bottom of the box girder; a vertical jack is adopted to integrally jack the beam body, the protection cushion blocks are gradually increased, the vertical jack synchronously falls back, the protection cushion blocks are gradually reduced, and the weight of the box beam is transferred to a sliding ship; the finish rolling deformed steel bars are pulled to transversely move along the sliding ways so as to drive the sliding ship and the box girder to transversely move; after the box girder moves to a designated position, the box girder is jacked up through a jack, a protection cushion block is placed in the box girder, and the transverse moving walking system is dismantled; and a support is installed at the bottom of the box girder, then the vertical jacks fall back synchronously, the protection cushion blocks are removed, the support makes contact with the supporting face for supporting, and overall displacement of the box girder is completed. In this way, the box girder can be integrally shifted in the valley high altitude, and compared with a traditional support cast-in-place method, the technical content is high, and the safety risk is reduced.
本发明涉及桥梁技术领域，具体涉及一种高铁现浇箱梁空中整体移位方法，包括在箱梁顶升过程中安装保护垫块；在箱梁底部安装横移走行系统；采用竖向千斤顶将梁体整体顶升，逐步增加保护垫块，同步回落竖向千斤顶，逐步减少保护垫块，将箱梁重量转移到滑船上；牵引精轧螺纹钢沿滑道进行横移，以带动所述滑船和箱梁横移；在箱梁移动到指定位置后，通过千斤顶将箱梁顶起并放入保护垫块并拆除横移走行系统；在箱梁底部安装支座，之后同步回落竖向千斤顶并去除保护垫块，使得支座和支撑面接触进行支撑，完成箱梁的整体移位。通过上述方式可以使得箱梁在山谷高空中整体进行移位，相对于传统支架现浇方法，技术含量高，降低了安全风险。
