Construction method for overhead jacking of multi-track existing line of frame structure bridge
The invention provides a construction method for the overhead jacking of the multi-track existing line of a frame structure bridge, through the construction mode of transition overhead, precipitation construction, formal overhead and two-end opposite jacking and middle cast-in-place, the risk caused by the underground water level to hole digging and pile forming is directly avoided; the overall construction scheme of the overpass pipe joint follows the principles of segmented construction and line production, the jacking part of the overpass is firstly constructed, and then the middle part frame is cast in situ after jacking in place, so that the railway operation safety is guaranteed, the construction period quality is also guaranteed, and good economic benefits and construction guiding significance are achieved.
一种框构桥架空顶进多股道既有线的施工方法，通过过渡架空—降水施工—正式架空及两头对顶‑中间现浇的施工方式，直接规避了地下水位对挖孔成桩造成的风险；立交桥管节总体施工方案遵循分段施工、流水作业的原则，立交桥先施工顶进部分，顶进就位后，再现浇中间部分框架，既保证铁路运营安全，又保证工期质量，具有较好的经济效益与施工指导意义。
