PILE HOLE FORMATION DEVICE
To provide a pile hole formation device that could reduce a risk of deflection or twisting of a communication wire.SOLUTION: A pile hole formation device has a plurality of auger rods 10, 20 connected in a vertical direction, and an auger head provided at a tip of the auger rod 10 at a distal end. The pile hole formation device includes: a through hole formed by penetrating the auger head in the vertical direction; a penetration rod 52 provided to move in the vertical direction continuously through a hollow part inside the auger rod 10 at the distal end and the through hole; a measurement cone connected to a bottom end of the penetration rod 52; a three-component sensor for measuring resistance force generated when the measurement cone penetrates into the ground; a communication wire 54a that is connected to the three-component sensor, passes through the hollow part of the rod, is exposed through an opening formed on the penetration rod 52, and passes inside the auger rod 10 at the distal end; a cable chain 74 for housing at least a part of the communication wire 54a; a wire 75 for supporting a prescribed portion of the communication wire 54a; and a reel 76 for moving the wire 75 in the vertical direction.SELECTED DRAWING: Figure 4
【課題】通信線に撓みや捻じれが生じるおそれの低減を図ることが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10,20が接続され、先端のオーガロッド10の先端部にオーガヘッドを有する。オーガヘッド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10の中空部内と貫通孔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と、測定コーンを地盤内に貫入させる際の抵抗力を測定する3成分センサと、3成分センサに接続され、前記ロッドの中空部を通り、貫入用ロッド52に形成された開口を介して露出し、先端のオーガロッド10の内部を通る通信線54aと、通信線54aの少なくとも一部を収容するケーブルチェーン74と、通信線54aの所定部分を支持するワイヤ75と、ワイヤ75を上下方向に移動させるリール76とを備える。【選択図】図4
