The I-line tunnel and the II-line tunnel both pass through the geological fault zone.
In fig. 1-7, rails 411, 412 form a transportation line 41# at the exit section of the tunnel. The steel rail 4211, the steel rail 4212, the steel rail 4221 and the steel rail 4222 form a three-line four-track of the flat tunnel, namely four tracks capable of forming three flat guide transportation lines, a flat guide tunnel small TBM machine excavation section transportation line 421# formed by the steel rail 4211 and the steel rail 4212, a flat guide tunnel small TBM machine excavation section transportation line 422# formed by the steel rail 4221 and the steel rail 4222 are drawn in a simplified drawing form in fig. 2, 3 and 5, but the flat guide tunnel small TBM machine excavation section transportation line formed by the steel rail 4212 and the steel rail 4221 is not shown. Rails 511, 512, 521 and 522 form a double-track four-track tunnel, i.e., a four-track tunnel capable of forming two tunnel transportation lines.
Example 1: the utility model provides a material dregs transportation method is used in TBM tunnel construction, the tunnel includes I line tunnel, II line tunnels and many auxiliary channel 3 that communicate I line tunnel and II line tunnels, wherein, adopt large-scale TBM machine 92 one shot forming to excavate the main tunnel 2 that is used for forming I line tunnel, adopt small-size TBM machine 91 to excavate the flat tunnel 1 that is used for forming II line tunnels, it is little to utilize small-size TBM machine 91 to excavate the section, the advantage of the excavation progress is fast is surveyed the disconnected regional of geology in advance, consolidate the back of handling, make large-scale TBM machine 92 can step-by-step geological fault region through main tunnel 2 to large-scale TBM machine 92 excavates the main tunnel. In this embodiment, the large TBM machine 92 is a shield machine with a cross-sectional diameter of 9m, and the small TBM machine 91 is a shield machine with a cross-sectional diameter of 6.36 m. Based on the difference of the section diameters of the large TBM and the small TBM, the slag output amount of the large TBM is different, and after the flat tunnel is excavated by the small TBM, the flat tunnel needs to be expanded and excavated at the later stage, so that the required supporting materials are less.
When the small TBM 91 and the large TBM 92 are used for operation, the flat tunnel 1 and the main tunnel 2 need to have TBM starting operation conditions, so that firstly, a drilling and blasting method is adopted to excavate the end head of the flat tunnel, the end head of the main tunnel and an auxiliary channel in an end head area, so that the flat tunnel has the small TBM starting operation conditions, and the main tunnel has the large TBM starting operation conditions.
