PIPE BURYING METHOD
To provide a pipe burying method capable of preventing a pipe outer surface from being damaged.SOLUTION: A method for burying a pipe 1 includes: an excavation step for excavating the ground 4 to form a groove 5; a sieving step for sieving generation soil 8 generated by excavation into between soil 28 of small particle size of predetermined dimensions or below and soil 29 of a large particle size larger than the predetermined dimensions; a piping step for piping the pipe 1 in the groove 5; a first backfilling step for putting the soil 28 of small particle size into the groove 5 to backfill the place around the pipe with the soil 28 of small particle size; and a second backfilling step for putting and backfilling the soil 29 of large particle size on the layer 31 of the soil 28 of small particle size formed in the groove 5 in the first backfilling step.SELECTED DRAWING: Figure 16
【課題】管外面が傷付くのを防止することができる管の埋設方法を提供する。【解決手段】管１の埋設方法は、地面４を掘削して溝５を形成する掘削工程と、掘削によって発生した発生土８を所定寸法以下の小粒径の土２８と所定寸法より大きい大粒径の土２９とに篩い分けする篩い分け工程と、溝５内に管１を配置する配管工程と、小粒径の土２８を溝５に投入して、管周りを小粒径の土２８で埋め戻す第１埋戻工程と、第１埋戻工程において溝５内に形成された小粒径の土２８の層３１の上に、大粒径の土２９を投入して埋め戻す第２埋戻工程とを有する。【選択図】図１６
