PROBLEM TO BE SOLVED: To provide jacked-pipe moving equipment which horizontally moves a jacked pipe, suspended in an adit, to a starting position in a main vertical shaft in the state of placing it on a supporting base, and which prevents damage to an outer surface of the jacked pipe by eliminating friction associated with the movement of the jacked pipe during a pipe jacking operation. SOLUTION: A traversing guide rail 4 for making the supporting base 6 traverse between a suspending position and a starting one, and an advance/receding guide rail 5 for making the supporting base 6 advance/recede between the starting position and a complete-pushing one are installed on a foundation trestle 3. The supporting base 6 is provided with a hook 6f which makes the supporting base 6 on the guide rail 5 disengageably engaged with the foundation trestle 3. When the jacked pipe moved to the starting position is pushed from the rear under the state of the placement of the jacked pipe on the supporting base 6, the jacked pipe is jacked while the supporting base 6 travels on the guide rail 5. Thus, since the jacked pipe is moved integrally with the receiving base 6 when jacked, damage to the outer surface of the jacked pipe is prevented by virtue of the absence of the friction.
