構成させてなる細い筒体の掘進装置。Regarding a device for digging and laying a thin cylinder underground, a hydraulic medium-hole jack whose inner diameter and outer diameter are approximately the same is inserted into the front part of the cylinder between the cutting edge and the front part of the cylinder, A reaction force receiving member attached to the inner surface of the cylindrical body holds the medium-hole jack, the outer periphery of the cylindrical body and the inner periphery of the medium-hole jack are covered at the head of the cylindrical body, and the cutting edge is slidably sealed; A thrust receiving member is installed around the entire circumference of the head of the cutting edge to transmit the thrust during operation of the medium hole jack to the cutting edge, and equipment for advancing the cutting edge is installed. In order to allow the cutting edge to slide back and forth between the inner surface of the rear cylinder body and the inner wall of the cutting edge, the inner wall of the cutting edge at the rear of the medium hole jack is provided with unevenness all around the outer surface, and the inner peripheral surface is shaped like this. A rotary member is mounted so as to engage with the uneven portion, have claws around the entire circumference of the outer circumferential surface, and enable rotation but not move back and forth, and further to feed the mold in the rotational direction one by one. A spring member is attached to the inner surface of the cylinder, a claw member is provided connected to the spring member, the tip is pivotally connected to the claw member, and the rear end is connected to the piston head of the hydraulic jack to form a connecting member. A slender cylindrical excavation device in which a hydraulic jack with a short piston operating length for moving a rotor connecting member back and forth is mounted and held on a pedestal rigidly connected to a reaction force receiving member to constitute a rotating equipment.
