Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent soil in the circumference of an underground buried cable pipe from discharging by flow of underground infiltration rain water, underground water, etc., so as to become hollow. SOLUTION: In an excavated groove (E) for burying cable pipes in the underground, after the circumference of a cable pipe group A1, A2, A3, A4 laid in the excavated groove (E) is surrounded with a cable pipe group surrounding foam plastic body 20, the soil is backfilled in the excavation groove in the circumference of this cable pipe groove and the circumference of clearances and recesses between the cable pipes to form a soil discharge passage caused by underground infiltration rain water, underground water, etc., is surrounded so as to prevent the soil from discharging.
