[0041] specific implementation plan
[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] The invention is applied in the construction plan of segmented construction in the construction of super-long tunnels. Multiple inclined shafts are set along different sections of the main tunnel to increase the excavation section. In addition to excavating from the openings at both ends of the tunnel, a construction team is also set up to excavate from various inclined shafts, divide the long tunnel into several sections, and realize two-way construction of each section; Starting from both ends, the ballastless track is laid in advance in the tunnel segment that has been penetrated. Such a construction plan can not only shorten the tunnel construction period, but also improve construction safety.
[0044] The prerequisite for the laying of ballastless track before the overall penetration of the tu...
