PROBLEM TO BE SOLVED: To provide an apparatus for constructing a tunnel, capable of smoothly performing various works in the tunnel.SOLUTION: In an apparatus for constructing a tunnel 1, an erector mechanism 10 and a basket mechanism 20 are movable in a longitudinal direction with respect to a travelling base 2. Lower stage rail members 40 extending in the longitudinal direction are installed on both sides of the travelling base 2, respectively. Base bodies 60 for an erector are attached to the lower stage rail members 40, respectively, and the base bodies 60 for the erector are movable along the lower stage rail members 40, and the erector mechanism 10 is supported by the base bodies 60 for the erector. On the other hand, upper stage rail members 50 extending in the longitudinal direction are installed above the lower stage rail members 40, respectively, base bodies 70 for the basket are attached to the upper stage rail members 50, respectively, the base bodies 70 for the basket are movable along the upper stage rail members 50, and thus the basket mechanism 20 is supported by the base bodies 70 for the basket. |
