Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent floating of a pipe caused by placing fluidized earth in a ditch, with excellent workability in a pipe burying construction method adopted to gas conduit burying work or the like. SOLUTION: A cord member 60 with both ends fitted to a fixed member buried in fluidized earth and fixed in the fluidized earth by solidification of the fluidized earth is installed in such a way as to pass the upper part of a pipe 20 laid in a ditch 10. Fluidized earth is backfilled into the buried depth of the fixed member 61 at a deeper part than the laid depth of the pipe 20 in the ditch 10 where the pipe 20 is laid, and after the fixed member 61 is fixed in the fluidized earth by solidification of the backfilled fluidized earth, the fluidized earth is backfilled into a part shallower than the laid depth of the pipe 20.
