Track reinforcing method for jacking of suspension type railway underneath pass box culvert
The invention discloses a track reinforcing method for jacking of a suspension type railway underneath pass box culvert. The method comprises the steps that a hole is drilled or dug on a foundation outside a track, reinforcing piles are constructed, and supporting beams and U-shaped suspenders are constructed after the strength of the reinforcing piles meets the design requirement; then fixing plates are welded to the bottom ends of the U-shaped suspenders, in the non-operation period of a railway, cross beams penetrate through the track on the fixing plates and are fixed through bolts, and the two ends of the cross beams are welded to the fixing plates; and finally, a foundation pit is excavated on the outer side of the track and between the reinforcing piles, a prefabricated box culvert is manufactured and pushed to the designed position through a jack while excavation is conducted, then the space between the top face of the box culvert and the track is filled with gravel to be squeezed tightly, the reinforcing piles, the supporting beams, the cross beams, the bolts, the U-shaped suspenders, the fixing plates and the like are dismantled, and part of components can be recycled and reused.
本发明公开了一种悬吊式铁路下穿箱涵顶进的轨道加固方法，该方法在轨道以外基础上钻孔或挖孔，施工加固桩，待加固桩强度达到设计要求后，施工支撑梁和U形吊杆；然后在U形吊杆底端焊接固定板，在铁路非运营期间，在固定板上将横梁穿过轨道，用螺栓固定，横梁两端均与固定板焊接；最后在轨道外侧、加固桩之间开挖基坑，制作预制箱涵，边挖边用千斤顶顶推至设计位置，然后在箱涵顶面与轨道之间填充碎石挤紧，拆除加固桩、支撑梁、横梁、螺栓、U形吊杆、固定板等，其中部分构件可回收重复利用。
