PILE EXTRACTION METHOD
To provide a pile extraction grab and a pile extraction method capable of securely removing an existing pile in a ground.SOLUTION: A pile extraction grab 1 comprises: a base portion 2; a pair of grab bodies 3 whose upper end sides are connected with the base portion 2 via a hinge 6, whose lower end sides can oscillate, which can clamp an existing pile P in a ground G by closing the lower end side, and which respectively have a semi-cylindrical surface shape; and a grab driving mechanism 4 capable of giving different oscillation angles to each grab body 3 of the pair of grab bodies 3 when clamping the existing pile P.SELECTED DRAWING: Figure 1
【課題】地盤中の既設杭を確実に除去することが可能な杭抜き用グラブ及び杭抜き方法を提供する。【解決手段】基部２と、基部２に上端側がヒンジ６を介して接続され下端側が揺動可能となっており、前記下端側を閉じることによって地盤Ｇ中の既設杭Ｐを掴むことが可能な、それぞれ半円筒面状をなす一対のグラブ本体３と、既設杭Ｐを掴む際に、一対のグラブ本体３のそれぞれのグラブ本体３に異なる揺動角度を与えることが可能なグラブ駆動機構４と、を有する杭抜き用グラブ１を構成する。【選択図】図１
