HOLE DRILLING DEVICE
PROBLEM TO BE SOLVED: To enable cost to be reduced and a construction period to be shortened in a small bore steel pile construction method.SOLUTION: A hole drilling device according to this invention comprises: a guide cell, whose lower end in an extending direction is located above a ground surface at least when the guide cell is held in upright state where the extending direction is perpendicular to the ground surface; a drifter, which is installed on the guide cell and can move in the extending direction of the guide cell; and a centralizer, which is installed on the guide cell and can change relative position to the drifter by moving in the extending direction of the guide cell.SELECTED DRAWING: Figure 3
【課題】小口径鋼管杭工法におけるコストの抑制や施工期間の短縮を可能にする。【解決手段】本発明の削孔装置は、少なくとも延在方向が地上面と直交する直立状態で保持されたときに、前記延在方向における下端部が前記地上面よりも上方に位置するガイドセルと、前記ガイドセルに設けられ、前記ガイドセルの延在方向に移動可能なドリフタと、前記ガイドセルに設けられ、前記ガイドセルの延在方向に移動して前記ドリフタとの相対位置を変化可能なセントライザと、を備えたことを特徴とする。【選択図】 図３
