CONSTRUCTION METHOD AND CONSTRUCTION MACHINE OF HYDRAULIC-SETTING SOLIDIFICATION MATERIAL LIQUID SUBSTITUTION COLUMN
PROBLEM TO BE SOLVED: To provide a construction method and a construction machine of a hydraulic-setting solidification material liquid substitution column, without causing construction occurrence surplus soil, without becoming finished-shape failure by collapsing a hole wall in the vicinity of a hole opening, and without becoming a poor quality since collapsed sediment drops in a constructed substitution column.SOLUTION: A pressurization board 11A capable of being penetrated by an excavation device is installed in a hydraulic-setting solidification material liquid substitution column installing position vicinal ground surface part, and the pressurization board 11A is pressurized downward with a construction machine as reaction, and a hydraulic-setting solidification material liquid substitution column is constructed.SELECTED DRAWING: Figure 2
【課題】建設発生残土が生じたり、孔口付近の孔壁が崩壊して出来形不良になったり、崩壊土砂が築造した置換コラム中に落下して品質不良になることがない水硬性固化材液置換コラムの築造方法と施工機を提供する。【解決手段】水硬性固化材液置換コラム打設位置近傍地表部に、掘削装置が貫通可能な加圧盤１１Ａを設置して、施工機を反力にして加圧盤１１Ａを下方に加圧して、水硬性固化材液置換コラムの築造をする。【選択図】図２
