装置。 An eccentric bearing bushing having an eccentric hole inside a fixed cylinder that is coaxial with the center line is slid onto the external tip of a propulsion device for underground pipe work, and the shaft is passed through the eccentric hole. The collar is fitted and fixed, for example, at the rear of the eccentric bearing bushing of the shaft through a key, and by moving the shaft forward, it engages with the rear end surface of the eccentric bearing bushing with a ratchet tooth having two circumferential teeth; The other collar is loosely fitted in front of the eccentric bearing bush of the shaft and connected to the fixed part so as not to rotate, and by moving the shaft rearward,
A device for correcting the propulsion direction of an underground pipe, which meshes with the front end surface of the eccentric bearing bushing with ratchet teeth that mesh at any position, has an excavation tool fixed to the tip of the shaft, and has a screw for earth discharge and subsequent feeding attached to the outer periphery of the shaft. .
