Jacking construction method for transversely moving firstly and longitudinally moving secondly through railway frame bridge
The invention discloses a jacking construction method for transversely moving firstly and longitudinally moving secondly for an underpass railway frame bridge, guard piles are constructed on the sides, close to a railway and a highway, of a working pit, and the guard piles are arranged between the left and right sides of the highway to form a central separation zone, so that safe operation of the railway and a highway operation line is greatly protected; a road is divided into a left road part and a right road part according to the passing direction, the left road part and the right road part are constructed in sequence, and when one road part is constructed, normal passing of the other road part can be kept; in the construction process, the sliding plate system is used for being matched with the jacking prefabricated frame bridge to transversely move and jack the prefabricated frame bridge to the highway and then steer to longitudinally move and jack the prefabricated frame bridge to the position below the railway in the highway direction, dismantling and jacking construction of the overhead supporting piles below the railway are conducted in the skylight time, and stability of a line reinforcing system is guaranteed in the passing period; the road occupation time of the existing expressway is integrally and obviously reduced, and the method can be widely applied to the flyover crossing construction of the reorganization and extension highway and the existing railway operation line.
本发明公开了一种下穿铁路框架桥先横移后纵移的顶进施工方法，在工作坑临近铁路和公路侧施工防护桩，且在公路左右两幅之间设置防护桩形成中央分隔带，极大保护铁路和公路运营线的安全运行，将公路按照通行方向分为左右两幅分别依次施工，施工其中一幅的同时，能够保持另一幅公路正常通行，预制框架桥施工前在铁路外侧设置顶进初始位置，施工过程中利用滑板系统配合顶进预制框架桥先横移顶进到公路上然后转向沿公路方向纵移顶进至铁路下方，对铁路下方架空支撑桩的拆除和顶进施工利用天窗时间进行，在通行期间保证线路加固体系的稳定，整体显著减少了既有高速公路占路时间，可广泛用于改扩建公路与既有铁路运营线的立体交叉施工。
