Railway underneath pass box culvert jacking rail reinforcing method
The invention discloses a railway underneath pass box culvert jacking rail reinforcing method, belongs to the field of road bridges and culverts, and is applicable to box culvert jacking construction for guaranteeing normal operation of railways. A technology is reliable and safety is high, during construction, holes are drilled or dug in a rail foundation, supporting piles are poured, and crown beams are constructed after the strength of the supporting piles meets a design requirement; then, in the non-operation period of the railway, a sleeper beam penetrates between supporting sleepers (permanent structures) below a railway track, holes are formed in flange plates at the bottom of the track, and the two are connected into a whole through bolts; and finally, a foundation pit is excavated on the rail foundation which is perpendicular to the rail and distributed between the supporting piles, a prefabricated box culvert is constructed, and after the box culvert is pushed to perpendicularly penetrate through the sleeper beam rail to a designed position, the space between the box culvert and the rail is filled with gravels to be squeezed tightly. And the sleeper beam and the top beam are removed, wherein the sleeper beam can be repeatedly utilized.
本发明公开了一种铁路下穿箱涵顶进轨道加固方法，属于道路桥涵领域，该技术适用于保证铁路正常运营的箱涵顶进施工，技术可靠，安全性较高，施工时，在轨道基础上钻孔或挖孔，浇筑支撑桩，待支撑桩强度达到设计要求后，施工冠梁；然后在铁路非运营期间，在铁路轨道下方的支撑枕木(永久结构)之间穿入枕梁，并在轨道底部翼缘板上开孔，用螺栓将两者连接成整体；最后在垂直于轨道且分布于支撑桩之间的轨道基础上开挖基坑，施工预制箱涵，顶推箱涵垂直穿过枕梁轨道至设计位置后，在箱涵与轨道之间填充碎石挤紧。再撤去枕梁和冠梁，其中枕梁可实现重复利用。
