CASING FOR REMOVING PILE, AND GROUND LOOSENING DEVICE AND GROUND LOOSENING METHOD FOR REMOVING PILE
To provide a casing for removing piles, and a ground loosening device and ground loosening method for removing piles which can make the adhering ground adhering to an outer peripheral surface of a pulled-out existing pile easily fall, thus a backfill amount of backfill soil can be accurately specified and further a backfill amount of backfill soil does not increase more than necessary.SOLUTION: A casing 50 for removing piles which loosens an adhering ground G1 adhering to an outer peripheral surface 12 of a pile 10 when removing the pile 10 remaining in the ground G has: a casing body 20 with a larger diameter than the pile 10; and an annular mesh-like surface material 30 attached to at least a lower end 22 of the casing body 20 or an inner surface 21 near the lower end to surround the pile 10.SELECTED DRAWING: Figure 1
【課題】引き抜かれた既存杭の外周面に付着する付着地盤を落下させ易くでき、このことによって、埋戻し土の埋戻し量を精度よく特定することができ、さらには、埋戻し土の埋戻し量を必要以上に多くさせることのない、杭撤去用のケーシングと、杭撤去用の地盤解し装置及び地盤解し方法を提供すること。【解決手段】地盤Ｇ内に残存する杭１０を撤去する際に、杭１０の外周面１２に付着する付着地盤Ｇ１を解す、杭撤去用のケーシング５０であり、杭１０よりも大径のケーシング本体２０と、ケーシング本体２０の少なくとも下端２２もしくは下端近傍の内面２１に取り付けられて杭１０を包囲する、環状でメッシュ状の面材３０とを有する。【選択図】図１
