Jacking construction method and device for railway underneath passing frame structure bridge
The invention relates to the field of jacking construction of an underpass railway frame structure bridge, and mainly relates to a jacking construction method of an underpass railway frame structure bridge, which specifically comprises the following steps: S1, construction preparation work; s2, the sleeper wall and the sound barrier are dismantled; s3, stress relief; s4, rail beam construction; s5, constructing a transverse lifting beam; s6, reinforcing the line; s7, digging a working pit; s8, prefabricating a frame structure bridge; s9, jacking the frame structure bridge; and S10, recovering the line. According to the method, the frame-structure bridge is prefabricated, then the frame-structure bridge is tested to be jacked, and then the frame-structure bridge is jacked for several times until the jacking construction of the frame-structure bridge is completed, so that the jacking speed and efficiency of the frame-structure bridge are improved by several times of jacking; and meanwhile, constructors can control the jacking precision of the frame-structure bridge and correct deviation in time when the frame-structure bridge deviates, the frame-structure bridge jacking construction method not only reduces the frame-structure bridge jacking construction error, but also improves the frame-structure bridge jacking construction precision, and meanwhile reduces the total cost input of frame-structure bridge jacking construction.
本发明涉及下穿铁路框构桥的顶进施工领域，主要是涉及一种下穿铁路框构桥顶进施工方法，其具体包括以下步骤：S1、施工准备工作；S2、拆除轨枕墙、声屏障；S3、应力放散；S4、轨束梁施工；S5、横抬梁施工；S6、线路加固；S7、挖取工作坑；S8、预制框构桥；S9、顶进框构桥；S10、线路恢复。本发明通过预制框构桥，然后试顶进框构桥后再对框构桥进行分次顶进，直至框构桥顶进施工完成，分次顶进不仅有利于提高框构桥的顶进速度和效率，同时还使得施工人员能够控制框构桥的顶进精度和在框构桥出现偏差时及时进行纠偏，该框构桥顶进施工方法不仅降低了框构桥顶进施工误差，而且提高了框构桥顶进施工精度，同时降低框构桥顶进施工的总成本投入。
