To reduce the burden of work.SOLUTION: A drilling method is a method using a drilling apparatus 1 that comprises a drill 10 having a rotary shaft 11 and a spiral blade 12 provided around the rotary shaft 11 and generating earth and sand ES in a hole HO by excavating the ground GR while forming the hole HO while rotating and lowering, and a compaction body 20 provided above the drill 10 and compacting the earth and sand ES onto a wall WA of the hole HO by rotating and lowering with the drill 10. In the drilling method, the earth and sand ES in the hole HO which has not been compacted in the wall WA is discharged out of the hole HO by pulling out the drill 10 and the compaction body 20 which have been lowered to the desired depth from the hole HO.SELECTED DRAWING: Figure 2
【課題】作業の負担を軽減する。【解決手段】掘削方法は、回転軸１１、及び回転軸１１の周囲に設けられている螺旋状の刃１２を有し、回転及び下降をしながら地盤ＧＲを掘削して穴ＨＯを形成することで穴ＨＯの中に土砂ＥＳを発生させるドリル１０、並びにドリル１０の上方に設けられ、ドリル１０と共に回転及び下降をすることで土砂ＥＳを穴ＨＯの壁ＷＡに圧密する圧密体２０を有する掘削装置１を用いる方法である。掘削方法は、所望の深度まで下降をしたドリル１０及び圧密体２０を穴ＨＯから引き抜くことで、壁ＷＡに圧密されなかった穴ＨＯの中の土砂ＥＳを穴ＨＯの外に排出する。【選択図】図２
