Cast-in-place and transverse moving combined supporting system for railway box girders adjacent to existing high-speed rail
The invention belongs to the technical field of box girder supporting, and particularly relates to a cast-in-place and transverse moving combined supporting system for a railway box girder adjacent to an existing high-speed rail. In the supporting system, a cast-in-place support system is arranged on the side, away from an existing high-speed rail line, of every two adjacent pier columns, a box girder cast-in-place formwork is supported on the cast-in-place support system, steel bars are bound in the box girder cast-in-place formworks, pouring of concrete box girders is completed, and after the cast-in-place box girders reach certain strength, the box girder cast-in-place formworks on the cast-in-place support system are dismantled. The sliding lifting system drives the cast-in-place box girder to slide from the top of the disc buckle type support to the top of the pier column, and the cast-in-place box girder falls 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现浇及横移组合支撑体系。在该支撑体系中，在两相邻墩柱远离既有高铁线路一侧设置现浇支架系统，现浇支架系统上支撑有箱梁现浇模板，在箱梁现浇模板中绑扎钢筋，并完成混凝土箱梁的浇筑，待现浇箱梁达到一定强度后，拆除现浇支架系统上的箱梁现浇模板，由滑移升降系统带动现浇箱梁从盘扣式支架顶部滑移至墩柱顶部，并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。
