It will fall off. Along with this, in the image of the monitor (14), the light emitting body (11) moves below the intersection of the reference line (15), and at this time, the worker can finally detect that the propulsion direction is deviated, In order to eliminate this deviation, the propulsion direction must be readjusted upward.

As described above, the conventional detection mechanism may not be able to accurately detect the actual propulsion direction from the image on the monitor. In such a case, the propelling direction is not displaced until the pushing propulsion is further continued. Can be detected. Therefore, the correction of the propulsion direction is delayed by one tempo, which necessitates another direction correction, which increases the frequency of the direction correction work and complicates the pipe burying work. Further, generally, the correction of the propulsion direction is not easy because of the resistance of the earth and sand acting on the pilot pipe or the like, and it is difficult to repeat the above-described correction of the direction. Therefore, the pilot pipe may reach the reaching vertical shaft while being displaced from the specified position.
