PILE HOLDING APPARATUS
PROBLEM TO BE SOLVED: To provide a light-weight pile holding apparatus capable of stably maintaining a holding state of a precast pile in place.SOLUTION: A pile holding apparatus 100 holds a precast pile 10 in a generally vertical direction at an opening 50a of a pile hole 50 when installing the same. The pile holding apparatus 100 includes: a holding cylinder 102 having a generally cylindrical shape, which is wound on the outer peripheral surface 12c of the precast pile at a predetermined position; and at least four vertical ribs 120 radially formed protruding from the outer peripheral surface 102d of the holding cylinder at a predetermined angular-distance along an axial direction of the holding cylinder. The length of the vertical rib in a diameter direction of the holding cylinder is larger than 1/2 of a difference between the inner diameter of the pile hole and the outer diameter of the precast pile.
【課題】装置の軽量化を図った上で既製杭の定位置での安定した保持状態の維持できるようにする杭保持装置を提供する。【解決手段】杭孔５０に既製杭１０を建て込む際に、杭孔の開口部５０ａで既製杭を略鉛直方向に保持可能な杭保持装置１００であって、既製杭の外周面１２ｃの所定の部位に巻着される略円筒形状の保持筒体１０２と、保持筒体の外周面１０２ｄから当該保持筒体の軸方向に沿って所定の角度間隔で放射状に突出するように設けられる少なくとも４つの縦リブ１２０とを備え、保持筒体の径方向における縦リブの長さは、杭孔の内径と既製杭の外径との差の１／２より大きいことを特徴とする。【選択図】図３
