Unbalanced cantilever beam body dismantling construction process
The invention provides an unbalanced cantilever beam body dismantling construction process, which belongs to the technical field of bridge construction, and comprises the following steps: preparing for construction, disassembling a cantilever beam body, installing a bridge girder erection machine, enabling a disassembled T beam to be positioned between supporting legs on two sides, and then hoisting and dismantling. And then the bridge girder erection machine is controlled to move transversely, and then the next T-beam is hoisted and dismantled. A support does not need to be erected on a railway, the construction risk is reduced, the construction progress is accelerated, the construction cost is reduced, and the leg separating mode of the bridge girder erection machine can meet the hoisting requirement of a cantilever beam body. And the bridge girder erection machine which is arranged in a split manner is adopted for integrally hoisting and disassembling the T-shaped beam, and the bridge girder erection machine works in a straight-in and straight-out manner, so that the requirements on a construction site can be reduced, the influence of surrounding buildings and protection trees is overcome, and the defect that hoisting and rotating of a crane cannot be realized is overcome.
本发明提供了一种不平衡悬臂梁体拆除施工工艺，属于桥梁施工技术领域，包括施工准备、悬臂梁体解体、安装架桥机，使得分解出来的所述T梁位于两侧支腿之间，再进行吊装拆除；之后控制所述架桥机横向移动，再进行下一T梁的吊装拆除。本发明不需在铁路上搭设支架，降低了施工风险，加快了施工进度，降低了施工成本，架桥机的分腿模式可满足悬臂梁体的吊装需求。并且采用分腿设置的架桥机进行T梁整体吊拆，架桥机作业为直进直出方式，可以减少对施工场地的要求，克服周围建筑、保护树木的影响，克服吊车的吊装、旋转无法实现的缺陷。
