PILE PULLING DEVICE AND PILE PULLING METHOD
To provide a pile pulling device and a pile pulling method capable of reliably pulling out an existing pile at a low cost.SOLUTION: A pile pulling device 10 includes a cylindrical casing 11 through which an existing pile P is passed, and a support mechanism 12 provided on a wall portion of the casing 11. The support mechanism 12 has a main body 19 fixed to the wall portion, a swing member 20 that is connected to the main body 19 via a hinge 25 and that can swing between a storage position which is close to the inner wall of the casing 11 so as to stand upward from the hinge 25, and a protruding position which is inclined so as to collapse from the storage position toward the axial center side of the casing 11, and a stopper 21 that comes into contact with the swing member 20 and regulates the tilt angle of the swing member 20 at the protruding position. The swing member is positioned in the protruding position due to its own weight and swings from the protruding position toward the storage position due to the contact force accompanying the contact with the existing pile P.SELECTED DRAWING: Figure 1
【課題】既設杭の引き抜き作業を低コストでかつ確実に行うことが可能な杭抜き装置および杭抜き方法を提供する。【解決手段】内側に既設杭Ｐが通される円筒状のケーシング１１と、ケーシング１１の壁部に設けられる支持機構１２と、を備え、支持機構１２が、前記壁部に固定される本体部１９と、本体部１９とヒンジ２５を介して連結され、ヒンジ２５から上向きに起立するようにケーシング１１の内壁に接近した収納位置と、該収納位置からケーシング１１の軸心側に向かって倒れ込むように傾斜した突出位置との間で揺動可能な揺動部材２０と、揺動部材２０と当接して、揺動部材２０の前記突出位置での傾斜角度を規制するストッパ２１と、を有し、自重によって前記突出位置にあり、既設杭Ｐとの当接に伴う当接力によって前記突出位置から前記収納位置に向かって揺動する杭抜き装置１０を構成する。【選択図】図１
