Overpass construction method based on underpass heavy haul railway
The invention relates to the technical field of bridge construction, discloses an overpass construction method based on an underpass heavy haul railway, and aims to solve the technical problem that the overpass construction method in the prior art has certain limitation on the bearing weight of the railway so that the application range of the overpass construction method is relatively small. The method comprises the steps that the bridge body construction position is determined, the rail reinforcing range is determined according to the bridge body construction position, and wood sleepers penetrate into preset wood sleeper penetrating points according to the rail reinforcing range; steel rails are combined into a buckling rail bundle, and the buckling rail bundle is fixed to the wood sleepers through fastener bolts; a transverse lifting beam and a longitudinal outrigger are installed on the railway track, and the transverse lifting beam and the longitudinal outrigger are fixed on a pre-built fender pile; and a working pit is excavated in the bridge body construction position, meanwhile, the bridge body of the overpass which is manufactured in advance is jacked into the working pit, and the overpass body which is constructed is obtained. The construction method is low in cost, high in efficiency, high in safety coefficient, short in construction period and suitable for construction of the heavy-load underpass railway.
本发明涉及桥梁施工技术领域，公开了一种基于下穿重载铁路的立交桥施工方法，用于解决现有技术中的立交桥施工方法对铁路的承载重量有一定的限制，导致立交桥施工方法适用范围较小的技术问题。该方法包括：确定桥体施工位置，根据桥体施工位置确定轨道加固范围，根据轨道加固范围在预设的木轨枕穿入点穿入木轨枕；采用钢轨组合成扣轨束，并将扣轨束通过扣件螺栓固定在木轨枕上；在铁路轨道上安装横抬梁和纵挑梁，并将横抬梁和纵挑梁固定在预先建造的护桩上；在桥体施工位置开挖工作坑，同时将预先制作完毕的立交桥的桥体顶进工作坑内，得到施工完毕的立交桥体。本施工方法成本低、效率高、安全系数高、施工周期短，适用于重载下穿铁路的施工。
