The small-diameter propulsion method is a propulsion method that uses steel pipes and humid pipes of 250φ to 1,000φ. Conventionally, when holes are formed during small-diameter propulsion, in order to correct this, a propulsion device as shown in Figure 1 is used. had not been used. In Figure 1, 1
i7J' outside/17s2 is an inner tube, the front side of the inner tube 2 is the screw shaft 2b, the tip side is the axle) head 2a, and the inclined head 2a has a center riser 2ee inside the outer tube 1.
This prevents the tip from wobbling. During normal excavation, both the outer pipe and the inner pipe are fed while rotating in opposite directions, but if a bend in the hole occurs, the rotation is stopped and the shaft is propelled as it is. In this case, the tilting head 2a is eccentrically corrected diagonally upward in the drawing, so that it is rotated and propelled again. The excavated soil passes between the outer pipe 1 and the inner pipe 2 and is discharged by the screw shaft 2b.
