Construction method for erecting large-span box girder on railway bridge girder erection machine on overpass business line
The invention relates to construction of a highway-crossing-railway overpass, is suitable for erecting construction of large-span box girders or T girders on an overpass business line, and particularly relates to a construction method for erecting a large-span box girder on a railway bridge girder erection machine on the overpass business line. The technical problems that in current highway cross-railway bridge construction, railway operation is greatly affected, and the hoisting technology is prone to being affected by the natural environment are solved. According to the method, the type of a double-guide-beam bridge girder erection machine is selected according to the maximum weight of the erected box girder or T girder, and after the safety coefficient and the anti-overturning coefficient are fully calculated, a proper bridge girder erection machine is selected for via hole erection. A bridge girder erection machine frame girder is tightly combined with girder lifting, girder transporting and girder feeding, through various preparations before a blocking point and in-point safety measures, the procedures of girder feeding, girder bundling, walking, in-place, supporting, transverse connection and the like are conducted by fully utilizing railway business line II-level blocking for 115 min, and it is ensured that the box girder is safely and stably located on the top face of a temporary support on the top face of a bridge pier bent cap.
本发明涉及公跨铁立交桥的施工，适用于上跨营业线大跨度箱梁或T梁架设施工，具体为一种上跨营业线铁路架桥机架设大跨度箱梁施工方法。解决了目前公路跨铁路桥梁施工中对铁路运营影响较大且采用吊装技术易受自然环境影响的技术问题。本方法根据所架设箱梁或T梁最大重量，选用双导梁架桥机型号，在充分计算安全系数和抗倾覆系数后，选择合适的架桥机进行过孔架设。架桥机架梁与提梁、运梁、喂梁紧密结合，通过封锁点前各项准备及点内安全措施，充分利用铁路营业线II级封锁115min进行喂梁、捆梁、走行、就位、支撑、横联等工序，确保箱梁安全平稳就位于桥墩盖梁顶面的临时支座顶面。
