小口径シールド掘進機。 In a small-diameter shield excavator that excavates a tunnel by providing a bulkhead on the shield body to partition the face side and the inside of the machine, and using the segment to receive jack thrust, there is a partition wall on the inner peripheral side of the tail part of the shield body. A plurality of back-back prevention devices are provided to prevent back-back, and the back-back prevention devices are connected to a radial pin hole provided in the segment, a radial pin hole formed in the inner surface of the shield body, and a radius formed in the inner surface of the shield body. 1. A small-diameter shield excavator comprising: a pin hole in the same direction; and a pin detachably inserted into the pin hole and the pin hole from the inside of the segment.
