DEVICE FOR CONSTRUCTING HYDRAULIC SOLIDIFICATION MATERIAL LIQUID SUBSTITUTION COLUMN
PROBLEM TO BE SOLVED: To enable avoidance of discharge of an elastic return part of a borehole wall surface onto ground after the elastic return part is scraped off by an excavation rod when the excavation rod is pulled up from the borehole.SOLUTION: A large-diameter excavation rod 1a for excavating ground for formation of a substitution column, and a small-diameter connection rod 1b serving as a grip part of an auger motor for rotating the excavation rod 1a are provided. A connection part 1c between the excavation rod 1a and the connection rod 1b is formed in a cone shape.SELECTED DRAWING: Figure 1
【課題】 掘削ロッドを掘削孔から引き上げる際に、その掘削ロッドによって掘削孔壁面の弾性戻り分が削り取られて地上に排出されることを回避可能にする。【解決手段】 置換コラム形成のために地盤を掘削する径大の掘削ロッド1aとこの掘削ロッド1aを回転させるオーガーモータの把持部となる径小の接続ロッド1bとを備え、掘削ロッド1aと接続ロッド1bとの接続部1cを円錐状に形成した構成である。【選択図】 図1
