PILE HOLE FORMATION DEVICE
To provide a pile hole formation device that is applicable even when a pile diameter is small.SOLUTION: A pile hole formation device has a plurality of auger rods connected in a vertical direction, and an auger head 30 fitted at a tip of the auger rod at a distal end. The pile hole formation device includes: a through hole formed by piercing through the auger head 30 in the vertical direction; a penetration rod 52 formed to move in the vertical direction continuously in a hollow part of the auger rod at the distal end and the through hole 36; a measurement cone 51 connected to a bottom end of the penetration rod 52; a fluid pressure cylinder installed inside the auger rod at the distal end, for moving the penetration rod 52 downward inside the hollow part of the auger rod at the distal end and the through hole 36, and pushing the measurement cone 51 out of the auger head 30 and having the measurement cone penetrate into a ground; a solidification material force-feed pipe 61 having one end connected to the through hole 36 and the other end protruding out of the auger head 30; and a solidification material force-feed pipe formed inside the auger rod to extend in the vertical direction, the auger rod being connected to the auger rod at the distal end.SELECTED DRAWING: Figure 3
【課題】杭径が小径であっても適用可能な杭孔形成装置を提供する。【解決手段】杭孔形成装置は、上下方向に複数のオーガロッドが接続され、先端のオーガロッドの先端部にオーガヘッド３０を有する。杭孔形成装置は、オーガヘッド３０を上下方向に貫通して形成された貫通孔と、先端のオーガロッドの中空部内と貫通孔３６内とを連続して上下移動可能に設けられた貫入用ロッド５２と、貫入用ロッド５２の下端部に接続された測定コーン５１と、先端のオーガロッド内に設けられ、貫入用ロッド５２を下方に向けて先端のオーガロッドの中空部と貫通孔３６内を移動させ、測定コーン５１をオーガヘッド３０の外部に押し出して地盤内に貫入させる流体圧シリンダと、一端部が貫通孔３６と接続され、他端部がオーガヘッド３０の外部に突出する固化材圧送管６１と、先端のオーガロッドに接続されるオーガロッド内に上下方向に延びて形成された固化材圧送管とを備える。【選択図】図３
