By the way, when the propelling body is propelled in the soil in a bent state (including a state along an arcuate path), when pulling the buried pipe to the position of the propelling body in the soil,
It is necessary to use a buried pipe that can accommodate the above-mentioned bending condition. Therefore, in such a case, a general-purpose pipe that is flexible and inexpensive to accommodate the bending condition is used as the buried pipe, such as a flexible plastic pipe or a thin-walled corrugated pipe. Such a buried pipe has low tensile strength, and when the propulsion device moves the propellant in a direction opposite to the propulsion direction, a specific portion of the buried pipe, for example, a connection portion with the tip of the propellant in the propulsion direction, may be damaged. There was a problem in that the specific portion was damaged due to concentrated tensile force.
