PILE HOLDING APPARATUS
PROBLEM TO BE SOLVED: To provide a pile holding apparatus capable of stably maintaining holding state of a precast pile in place when installing a precast pile in a pile hole at construction site.SOLUTION: A pile holding apparatus 100 is capable of holding a precast pile in a vertical direction at an opening 50a of a pile hole when installing a precast pile 10 in a pile hole 50. The pile holding apparatus 100 includes a holding cylinder 102 having a generally cylindrical shape, which is wound to fix to the outer peripheral surface 12c of the precast pile at a predetermined position. The holding cylinder has an annular concave part which is formed in an annular shape along the inner peripheral surface of the holding cylinder. The annular concave part has a tapered plane 102c the diameter of which gradually increases from the bottom side of the inner peripheral surface in a generally vertical direction toward the apex side.
【課題】施工現場の杭孔に既製杭を建て込む際に、より確実に既製杭の定位置での安定した保持状態を維持するための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を備えており、当該保持筒体は、保持筒体の内周面に沿って環状に形成され、略鉛直方向における当該内周面の底部側から頂部側に向けて一定の割合で拡径して形成されるテーパ面１０２ｃからなる環状凹部を有することを特徴とする。【選択図】図２
