摘要： PROBLEM TO BE SOLVED: To provide a shield machine for underground connection capable of enlarging the wrapping allowance with a receiving hood as much as possible when the machine is put in the receiving hood arranged underground.
SOLUTION: The shield machine 1 for underground connection is fitted in the receiving hood 17 arranged underground and connected. A drive jack 7 of a slant copy cutter 6 retracting outwardly and forwardly in the radial direction of the head 2 is attached slantly in the diagonal and forward direction to the cutter head 2 cutting the heading. A fitting hood 10 forwardly extended so as to contain a part of the drive jack 7 inside is provided in the shielding machine body 11 in the rear side of the cutter head 20. As the drive jack 7 of the slant cutter 6 is slantly attached to the cutter head 2 in the diagonal forward, even if the fitting hood 10 provided in the shield machine body 11 is extended, the fitting hood 10 does not interfare with the drive jack 7 and the retracting motion of the slant copy cutter 6. Hence, when the machine is put in the receiving hood 17, the wrap allowance L1 gets larger than the conventional L2 and cuting off stability is improved.
