Double-width small-spacing curve steel box girder mounting method
The invention discloses a double-width small-spacing curve steel box girder mounting method, belongs to the technical field of bridge mounting, and is used for mounting a left-width bridge and a right-width bridge to avoid collision between the left-width bridge and the right-width bridge which are arranged side by side in the mounting process. According to the method provided by the invention, the curved box girder arranged on one of the bridge piers arranged side by side is lifted, the lifted curved box girder is jacked in by adopting a pushing method, the span between the two bridge piers is completed, then the curved box girder is descended and mounted on the two bridge piers, and due to the fact that one curved box girder is higher than the other curved box girder, the span between the two bridge piers is completed. And collision and rollover in the installation process of the curve steel box girder are avoided.
本发明公开了一种双幅小间距曲线钢箱梁安装方法，属于桥梁安装技术领域，用于左幅桥梁与右幅桥梁的安装，避免安装过程中并排设置的左幅桥梁与右幅桥梁发生碰撞。本发明提供的方法将并排设置的桥墩上其中一个桥墩上设置的曲线箱梁升高，并采用顶推法将升高的曲线箱梁顶进，完成两个桥墩之间的跨度，再将曲线箱梁下降并安装在两个桥墩上，由于其中一个曲线箱梁高于另一个曲线箱梁，避免在安装曲线钢箱梁的过程中发生碰撞和侧翻。
