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 The main tunnel 2 of the I-line tunnel is excavated at one time, and the flat guide tunnel 1 of the II-line tunnel is excavated by the small TBM machine 91. The small TBM machine 91 excavates the advantages of small excavation section and fast excavation progress to first excavate the geological fault 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 the difference...

The invention discloses a material and muck transporting method for TBM tunnel construction. A tunnel comprises a main tunnel, a parallel adit tunnel and an auxiliary channel used for communicating the main tunnel with the parallel adit tunnel. The parallel adit tunnel comprises a small TBM entrance segment and a small TBM tunneling segment. A temporary transporting line of dual rails is arrangedon the small TBM entrance segment. Three parallel adit transporting lines of four rails are arranged on the small TBM tunneling segment. A muck transporting belt and two main tunnel transporting linesof the four rails are arranged on the main tunnel. The tail of a large TBM crosses over the auxiliary channel, and after the parallel adit transporting lines are connected with the main tunnel transporting line through the auxiliary channel, a parallel adit transporting line extension line connected with the main tunnel transporting line is arranged in the auxiliary channel. During expanding excavation of the parallel adit tunnel, the parallel adit transporting lines are connected with the main tunnel transporting line through the auxiliary channel in front of the expanding excavation work face of the parallel adit tunnel, and then expanding excavation of the parallel adit tunnel is achieved through a borehole-blasting method. The method cooperates with the construction process, and material and muck transporting is matched with the excavation schedule.
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...
