Pushing platform erecting and disassembling method for large-span bridge pushing construction
The invention discloses a pushing platform erecting and disassembling method for large-span bridge pushing construction, which is characterized in that two ends of a bailey beam group are supported and erected on a supporting girder, the supporting girder is supported by a supporting bracket arranged on a pier and a temporary steel pipe stand column, an inhaul cable driven by a winch is arranged on the supporting girder, and the supporting girder is inclined and adjustable; when the bailey beam group is mounted or dismounted, the jacking cylinders are used for adjusting the supporting girders to incline inwards or outwards, then the winches are started, the inhaul cables are used for pulling the bailey beam group to move transversely inwards or transversely outwards in the inclination direction of the supporting girders, mounting or dismounting of the bailey beam group can be conveniently achieved, and the problem that after a bridge is pushed, the supporting girders incline inwards or outwards is effectively solved. And due to the obstruction of a cast-in-place beam above the pushing platform, the platform dismounting construction space is limited, a crane cannot be used for direct hoisting, and the Bailey beam is inconvenient to dismount.
本发明公开了一种大跨度桥梁顶推施工用顶推平台搭拆方法，该方法贝雷梁组的两端支撑搭在支撑大梁上，而支撑大梁通过布置在桥墩上的支撑牛腿以及临时钢管立柱支撑，在支撑大梁上设有卷扬机带动的拉索，而且支撑大梁倾斜可调，贝雷梁组安装或拆卸时，利用顶升缸将支撑大梁调节至向内或向外倾斜，之后启动卷扬机利用拉索拉动贝雷梁组顺着支撑大梁倾斜方向横向向内或横向向外移动，即可方便的实现贝雷梁组的安装或拆卸，有效解决了因桥梁顶推完成后，因顶推平台上方现浇梁的阻碍，使得平台拆卸施工空间有限，无法利用吊机直接起吊，造成贝雷梁拆卸不方便的问题。
