Mounting and dismounting method for railway box girder supporting system adjacent to existing high-speed rail
The invention belongs to the technical field of box girder supporting, and particularly relates to a mounting and dismounting method for a railway box girder supporting system adjacent to an existing high-speed rail. In the mounting and dismounting method, a supporting system is arranged between two adjacent pier columns and is far away from a high-speed rail line, so that the supporting system does not influence the operation of the existing high-speed rail line; a disc buckle type support is built on the sides, away from an existing high-speed rail line, of two adjacent pier columns, a box girder cast-in-place formwork is erected on the disc buckle type support, pouring of a concrete box girder is completed, after the cast-in-place box girder is manufactured, the box girder cast-in-place formwork on a cast-in-place support system is dismantled, the cast-in-place box girder is driven by a sliding shoe to slide from the top of the disc buckle type support to the tops of the pier columns, and the cast-in-place box girder is formed. Then the lifting mechanism falls to enable the cast-in-place box girder to fall on the top of the pier column; the construction of erecting the box girder on the pier column close to the existing high-speed rail line is completed, and the erecting operation of the box girder and the operation of the existing high-speed rail line do not influence each other, so that not only is the construction efficiency improved, but also the influence on the existing high-speed rail line is small.
本发明属于箱梁支撑技术领域，具体涉及一种邻近既有高铁的铁路箱梁支撑体系安拆方法。在该安拆方法中，将支撑体系设置在相邻两墩柱之间，且远离高铁线路设置，使得该支撑体系不会影响到既有高铁线路的运行；在两相邻墩柱远离既有高铁线路一侧搭建盘扣式支架，在盘扣式支架上架设箱梁现浇模板，完成混凝土箱梁的浇筑，待现浇箱梁制作完成后，拆除现浇支架系统上的箱梁现浇模板，由滑靴带动现浇箱梁从盘扣式支架顶部滑移至墩柱顶部，然后升降机构下落，使现浇箱梁落在墩柱顶部；完成在临近既有高铁线路的墩柱上架设箱梁的施工，且使得箱梁架设作业与既有高铁线路运行互不影响，不仅提高了施工效率，而且对既有高铁线路影响较小。
