Embodiment 1

[0030] Embodiment 1: A method for transporting materials and soil for TBM tunnel construction, the tunnel includes a line I tunnel, a line II tunnel and a plurality of auxiliary passages 3 connecting the line I tunnel and the line II tunnel, wherein a large TBM machine 92 is used Excavate the main tunnel 2 of the I-line tunnel with one-shot excavation, and use the small TBM machine 91 to excavate the flat guide tunnel 1 for the II-line tunnel. The small TBM machine 91 has the advantages of small excavation section and fast excavation progress, and the geological faults are first excavated. After the area is detected and reinforced, the large TBM machine 92 can step through the geological fault area of ​​the main tunnel 2, so that the large TBM machine 92 can dig the main tunnel. In this embodiment, the large TBM machine 92 selects a shield machine with a section diameter of 9 m, and the small TBM machine 91 selects a shield machine with a section diameter of 6.36 m. Based on t...

Abstract

A method for transporting materials and muck for TBM tunnel construction. The tunnel includes a main tunnel, a level guide tunnel, and an auxiliary channel for connecting the main tunnel and the level guide tunnel. The level guide tunnel includes a small TBM machine entry section and a small TBM machine excavation section. Set up a temporary two-track transportation line in the entry section of the small TBM machine, and three flat guide transportation lines with four tracks in the excavation section of the small TBM machine; set up a muck conveyor belt and two main tunnel transportation lines with four tracks in the main tunnel; After the tail of the large TBM machine crosses the auxiliary channel and the horizontal guide transport line can be connected with the main tunnel transport line through the auxiliary channel, an extension line of the horizontal guide transport line connected with the main tunnel transport line is set in the auxiliary channel; During the excavation of the level guide tunnel, the level guide transport line will be connected with the main tunnel transport line through the auxiliary channel in front of the excavation face of the level guide tunnel, and then the level guide tunnel will be expanded and excavated by the drill and blast method. The method is matched with the construction process, and the transport of materials and muck is matched with the progress of excavation.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a method for transporting materials and soil for TBM tunnel construction. Background technique [0002] The materials required for TBM tunnel construction include construction materials and equipment. During the excavation process of TBM tunnel, muck will be produced continuously, which needs to be transported out of the tunnel in time. Contents of the invention [0003] The technical problem to be solved by the present invention is that the excavation progress of the TBM tunnel does not match with the transportation of the muck, and the technical problem of large mutual interference between multiple working surfaces and processes. Therefore, the present invention provides a kind of muck used for TBM tunnel construction. Transport method. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technica...
