EXISTING PILE HOLDING APPARATUS
PROBLEM TO BE SOLVED: To reduce the inclination of the existing pile holding apparatus to improve workability when holding the existing pile by lowering the existing pile holding apparatus to the hole formed after bordering by the casing.SOLUTION: By swinging a first holding portion 31 and a second holding portion 32 around a first support shaft 33 and a second support shaft 34, the existing pile is held in the radial direction. An apparatus main body 2 is provided with an attitude stabilizing part 6 which contacts the inner surface of the hole formed in the ground so as to cut off the ground and the existing pile so as to suppress the inclination of the apparatus main body 2.SELECTED DRAWING: Figure 2
【課題】ケーシングによって縁切した後にできた孔に既設杭把持装置を降ろして既設杭を把持する場合に、既設杭把持装置の傾きを抑制して作業性を良好にする。【解決手段】第１把持部３１及び第２把持部３２を第１支軸３３及び第２支軸３４回りに揺動させることによって既設杭を径方向に把持する把持する。装置本体２には、地盤と既設杭とを縁切りするために当該地盤に形成された孔の内面に接触して装置本体２の傾きを抑制する姿勢安定化部６が設けられている。【選択図】図２
