Construction method for erecting curve section continuous steel box girder through bridge girder erection machine
The invention relates to a construction method for erecting a curve-section continuous steel box girder by a bridge girder erection machine. The construction method comprises the following steps: firstly, arranging a front supporting leg transverse moving track beam; supporting stand columns are fixed to the tops of the cover beams, and the transverse moving track beams are installed on the supporting stand columns through bolts; erecting a middle beam to a designed position, and welding to complete transverse connection to form a whole; then the supporting stand columns with conflicting positions are dismantled, a cushion is arranged on the top of the middle beam, and the edge beam is erected to the temporary support position; the bridge girder erection machine moves forwards, the transverse moving track beams move forwards along with the supporting legs, and meanwhile corresponding supporting structure conversion is completed; finally, the bridge girder erection machine withdraws after erecting all the steel girders, and the boundary girders welded into the continuous steel box girder are integrally and transversely moved to the designed position. The universality of the bridge girder erection machine frame girder can be enhanced, and the effects of improving the construction efficiency, shortening the construction period, reducing the construction cost and the like are achieved for erection of the curve section continuous steel box girder.
本发明涉及一种用于架桥机架设曲线段连续钢箱梁的施工方法，首先布置前支腿横移轨道梁；在盖梁顶固定支撑立柱，用螺栓将横移轨道梁安装在支撑立柱上；然后架设中梁至设计位置并焊接完成横向连接，形成整体；随后拆除位置冲突的支撑立柱，在中梁顶抄垫，架设边梁到临时支座位置；架桥机前移，横移轨道梁随支腿前移，同时完成相应支撑结构转换；最后架桥机架设全部钢梁后撤出，焊接成为连续钢箱梁的边梁整体横移至设计位置。本发明能够增强架桥机架梁的通用性，对曲线段连续钢箱梁架设起到提高施工效率，缩短工期，降低施工成本等作用。
