BURYING METHOD OF PLASTIC PIPE

摘要

PROBLEM TO BE SOLVED: To provide a burying method of a plastic pipe which suppresses that a gap is produced between an outer surface of the plastic pipe and liquid material when cast curable liquid material is cured and suppresses the floating of the plastic pipe.SOLUTION: A burying method of a plastic pipe includes: a first process (Fig.3(a)) in which the plastic pipe 3 subjected to ruggedness processing on the outer surface 3a is laid in a groove 5; a second process (Fig.3(b)) in which the upper side of the plastic pipe 3 is exposed in the groove 5 and curable liquid material 1b is cast; and a third process (Fig.3(c)) in which the liquid material 1b is cast in the groove 5 and the plastic pipe 3 is buried.
