Side position cast-in-place and transverse movement construction method for railway box girder adjacent to existing high-speed rail
The invention relates to the technical field of bridge construction, in particular to a side position cast-in-place and transverse movement construction method for a railway box girder adjacent to an existing high-speed rail. S2, cast-in-place operation is conducted; s3, carrying out transverse moving operation; s6, beam falling operation is carried out; the construction system comprises a support formwork system and a transverse moving system. The transverse moving system comprises transverse sliding shoes, transverse sliding ways and first temporary supports, the transverse sliding ways are symmetrically distributed on the two sides of the bottom of the railway box girder in the bridge direction, the transverse sliding shoes are arranged on the transverse sliding ways in a sliding mode in the transverse bridge direction, the transverse sliding ways stretch into the positions between bridge piers in the transverse bridge direction, and the first temporary supports are used for supporting the transverse sliding ways; the step S1 comprises the steps that part of the support formwork system is built on the top face of a pier, the pier, the transverse moving system and the support formwork system jointly form a supporting system for supporting railway box girder cast-in-place operation, and the pouring position of a railway box girder is primarily positioned in the bridge direction through the padstone position on the top face of the pier.
本申请涉及桥梁施工技术领域，特别涉及一种邻近既有高铁的铁路箱梁侧位现浇及横移施工方法，包括：步骤S1，施工系统搭建；步骤S2，现浇作业；步骤S3，横移作业；步骤S6，落梁作业；施工系统包括支架模板体系、横移体系；横移体系包括横向滑靴、横向滑道、第一临时支架，横向滑道沿顺桥向对称分布在铁路箱梁的底部两侧，横向滑靴沿横桥向滑动设置在横向滑道上，横向滑道沿横桥向伸入桥墩之间，第一临时支架用于支撑横向滑道；步骤S1包括：将部分支架模板体系搭建在桥墩的顶面，桥墩、横移体系和支架模板体系共同组成支撑铁路箱梁现浇作业的支撑体系，通过桥墩顶面的垫石位置对铁路箱梁的浇筑位置进行顺桥向的初次定位。
