(Problems to be Solved by the Invention) In the conventional boring machine shown in FIGS. 6 to 8, (I) the swing jack (12) is alternately operated in the arrow direction of FIG. Is transmitted to the clamp device (13) and the casing tube (1) through the link type swing arm (15), and the clamp device (13) and the casing tube (1) are swung in the arrow direction of FIG. Therefore, the casing tube (1) stops at the moment when the swinging direction is switched. Therefore, when swinging in the opposite direction after stopping, it is necessary to transmit to the casing tube (1) a force that overcomes the frictional resistance between the casing tube (1) and the hole wall. A force that overcomes this frictional resistance is necessary even when the casing tube (1) is pulled out, and large-sized swing rocking jacks (12) and push-in jacks (10) must be used, which is costly. (II) Further, the rocking jack (12) is alternately operated in the direction of the arrow in FIG. 7, and the movement is clamped through the link type rocking arm (15) to the clamp device (13).
And the casing tube (1), the boring machine becomes large in size due to the reciprocating motion and the oscillating motion of the oscillating jack (12) and the oscillating arm (15) of the same link, which also leads to cost up. . (III) Since only the casing tube (1) is swung, there is a problem that when the soft rock formation is encountered, the soft rock formation cannot be efficiently excavated.

(Effect of the Invention) Pushing the casing tube of the boring machine of the present invention
Since the pulling device pushes into the ground or pulls out from the ground while rotating the casing tube as described above, the force to overcome the frictional resistance between the stopped casing tube and the hole wall is transmitted to the casing tube. It is not necessary to use small ones for the rotary drive and lift drive, while rotating the casing tube,
Since it pushes in and pulls out, it does not require a rocking jack that reciprocates or a link-type rocking arm that rocks, and the boring machine can be downsized and the manufacturing cost can be reduced. While rotating the casing tube,
Since it is pushed into the ground, it has the effect of efficiently excavating soft rock formations.
