Zusammenfassung:	PURPOSE:To prevent the occurrence of cracks in a pipe buried by a method in which a pipe is set in a trench by exposing its partial portion and embedded, a vibrator is attached to the exposed portion of the pipe, and the pipe is vibrated to compact the embedded soil. CONSTITUTION:A pipe 13 is set in a trench 11 excavated in the ground's surface and the trench 11 is embedded in such a way as to expose a part of the pipe 13 on the ground. A vibrator 16 is attached to the exposed portion of the pipe 13 and the pipe 13 is vibrated, thereby effectively compacting the surrounding soil of the pipe 13, particularly the embedded soil below the pipe 13. The occurrence of cracks in the pipe 13 with its settlement can thus be prevented and the occurrence of gas and water leakage can also be prevented.
