METHOD AND DEVICE FOR CARRYING OUT MUCK CAPABLE OF REALIZING DOUBLE TRACK IN TUNNEL HAVING SMALL CROSS SECTION

摘要

PROBLEM TO BE SOLVED: To realize a double track of all lines including a section of a following bogie by adopting a muck carrying-out system using a belt conveyor and a muck transportation vehicle even in a tunnel having a small cross section. SOLUTION: A conveyor receive bogie 2 sharing a burden of supporting a belt conveyor 4 capable of changing a length of a section along the longitudinal direction of a tunnel in a section of length at the time of elongation is connected with a following bogie 1, and a muck steel vehicle 3 capable of supporting the belt conveyor 4 on an upper side and sharing a burden of supporting the belt conveyor 4 in a section of length entering a space below the belt conveyor 4 is connected with a rear side of the conveyor receive bogie 2 so as to engage and disengage freely. When the muck steel vehicle 3 enters a lower space of the belt conveyor 4 to load muck on the muck steel vehicle 3, the belt conveyor 4 in an entrance section part of the muck steel vehicle 3 is supported by the muck steel vehicle 3, and a belt conveyor part other than the entrance section of the muck steel vehicle 3 is supported by the conveyor receive bogie 2.
