DEVICE AND METHOD FOR MANUFACTURING HYDRAULIC SOLIDIFICATION MATERIAL LIQUID-SUBSTITUTED COLUMN, AND HYDRAULIC SOLIDIFICATION MATERIAL LIQUID-SUBSTITUTED COLUMN
PROBLEM TO BE SOLVED: To enhance vertical bearing capacity of a hydraulic solidification material liquid-substituted column and realize a high-strength and high-quality hydraulic solidification material liquid-substituted column, without significantly changing manufacturing processes thereof.SOLUTION: A discharge port 4 having a diameter from 3 mm to 10 mm is disposed on a drilling rod 1a or a conical head 2, the discharge port being for discharging hydraulic solidification material liquid at a discharge pressure sufficient for drilling or infiltrating into a ground around a hole drilled by the drilling rod 1a.SELECTED DRAWING: Figure 1
【課題】 施工手順を大幅に変更することなく、水硬性固化材液置換コラムの鉛直支持力が増大し、水硬性固化材液置換コラムの高強度・高品質化を実現可能にする。【解決手段】 掘削ロッド１ａや円錐ヘッド２に、掘削ロッド１ａによる削孔周面地盤中に掘削乃至滲入可能な吐出圧で水硬性固化材液を吐出する直径３ｍｍから１０ｍｍの吐出口４を設けた構成である。【選択図】 図１
