When the protective pipe 400 is installed in the underground pipeline 100, the underground power line L is laid in the underground pipe 100 and the present invention is buried.

When excavation is performed on the ground in this state, earth pressure is generated by the external force applied from the excavator, and the earth pressure is transmitted to the protective pipe 400. At this time, the protective pipe 400 and the filler material 500 buffer the earth pressure to prevent a great earth pressure from being applied to the underground pipe 100.

Also, when the excavator excavates near the underground pipe 100, if the operator advances the excavation without knowing the position of the underground pipe 100, the underground pipe 100 may be damaged by the excavator. However, in the present invention, the shovel of the excavator first impacts the protective pipe 400, so that the underground pipe 100 can be stably protected. Further, according to the present invention, not only the protective pipe 400 but also the filler material 500 relaxes the impact from the excavator shovel, so that the underground pipe 100 can be more stably protected.
