Tunnel ballastless track roadbed slab arching disease treatment method
The invention discloses a tunnel ballastless track roadbed slab upward arching disease treatment method which comprises the steps that grouting reinforcement and falling track cutting are conducted on a tunnel base, specifically, an upward arching section inverted arch filling layer is divided into a plurality of layers, cut concrete is taken out, the elevation of a roadbed slab is reduced, then the roadbed slab is sequentially connected with an unconstructed section through continuous fine adjustment, and then the tunnel base is subjected to grouting reinforcement and falling track cutting. Finally, filling layer gaps are poured through roadbed repairing materials, so that the lines return to normal. The tunnel ballastless track bed slab arch-up damage treatment method overcomes the difficulties of guaranteeing adjacent line driving safety, being short in effective operation time, poor in tunnel lighting environment, large in construction dust, how to transport and place construction materials and large mechanical equipment and the like, successfully achieves the treatment process of tunnel ballastless track bed slab arch-up damage, accumulates experience for treatment of similar tunnel ballastless track bed slab arch-up damage, and improves the treatment efficiency of the tunnel ballastless track bed slab arch-up damage. The adopted construction process and thought can be referenced and applied to similar projects; the construction task can be completed within limited time, safe passing and normal operation of the train are guaranteed after the skylight is finished, and the construction cost is low.
本发明公开了一种隧道无砟轨道道床板上拱病害整治方法,包括对隧道基底进行注浆加固和切割落道,切割落道是将上拱区段仰拱填充层分割为若干层,取出切割后混凝土降低道床板高程,再通过不断精调使道床板与未施工段落顺接,最后利用路基修补材料浇筑填充层空隙使线路恢复正常。本发明克服保证邻线行车安全、有效作业时间较短、隧道照明环境差、施工灰尘大、施工材料、大型机械设备如何运输放置等困难,成功实现隧道无砟轨道道床板上拱病害的整治过程,为类似隧道无砟轨道道床板上拱病害整治积累了经验,所采用施工流程及思路可在类似工程中参考应用;能够在有限时间内完成施工任务,并在天窗结束后保证列车安全通行和正常运营,施工成本较低。
