Two-way curved arch bridge dismantling structure and construction method
The invention provides a two-way curved arch bridge dismantling structure and a construction method. The two-way curved arch bridge dismantling structure comprises the main construction steps that a construction guide platform is constructed on a steel pipe pile bridge; constructing a space-limited Bailey beam mounting device; constructing a steel pipe pile guide beam; a unit bailey beam supporting frame is erected; an arch rib steel pipe support platform is erected; assembling the unit integral temporary floating pontoon; building a temporary floating pontoon slag falling platform; a pontoon type overwater construction platform; constructing a temporary pull anchor fixing structure of the pontoon; quickly cutting and dismantling the arch upright posts, and erecting a stable bracket; the beam body is cut and dismantled in a reversed-sequence segmented mode; determining the position of a blast hole; mounting a gun barrel; non-electric intelligent detonation network connection; erecting a combined covering protection structure at the bridge pier; building a protection structure for hanging a flexible protection object; building a near-body flexible protection structure; and two-way curved arch bridge partition blasting demolition. By means of the dismantling structure and the construction method, the two-way curved arch bridge dismantling project can be efficiently and safely carried out, and wide application prospects are achieved.
本发明提供一种双曲拱桥拆除结构及施工方法，其主要施工步骤包括：钢管桩桥上施工导向平台施工；空间受限贝雷梁安装装置施工；钢管桩导向梁施工；单元贝雷梁支撑架搭设；拱肋钢管支架平台搭设；单元整体式临时浮船组装；临时浮船落渣平台搭设；浮船式水上施工平台；浮船临时拉锚固定结构施工；拱上立柱快速切割拆除稳固支架搭设；逆序分段切割拆除梁体；确定炮孔位置；安装炮管；非电智能起爆网络连接；桥墩处组合覆盖防护结构搭设；悬挂柔性防护物防护结构搭设；近体柔性防护结构搭设；双曲拱桥分区爆破拆除。本发明通过拆除结构及施工方法，双曲拱桥拆除工程得以高效、安全地进行，具有广阔的应用前景。
