To provide an underground pile breaking method that reduces the occurrence of vibration, noises, and dust significantly so that it is resistant to use in city centers.SOLUTION: The underground pile breaking method includes: a step for piercing a breaking substance loading hole and shock absorption hole in the pile head of an underground pile along the longitudinal direction of the underground pile while the pile head is exposed; a step for inserting, from the pile head into the breaking substance loading hole, breaking substances and cement tampers alternately so that breaking substances are separate from each other in regular intervals in a manner of multiple layers along the longitudinal direction of the underground pile; and a step for breaking the pile by lighting the multiply layered, inserted breaking substances in order from the pile head to the bottom of the underground pile every predetermined period that ranges 0.025 to 0.5 seconds.SELECTED DRAWING: Figure 1
【課題】都心等における利用にも耐えられるように、振動と騒音と粉塵の発生をより低減した地中杭破砕方法を提案すること等を目的とする。【解決手段】杭頭が露出された状態の地中杭に、地中杭の長さ方向に沿って杭頭から破砕薬装填孔及び衝撃吸収孔を穿孔する工程と、杭頭から、破砕薬装填孔に、破砕薬とセメントタンパーとを交互に、破砕薬が一定の間隔となるように、地中杭の長さ方向に沿って多段に挿入する工程と、多段に挿入された破砕薬を、杭頭から地中杭の底部に向けて順次に、０．０２５秒〜０．５秒の範囲の一定時間毎に、着火して破砕する工程と、を有する地中杭破砕方法とする。【選択図】図１
