DRILLING METHOD AND CONSTRUCTION METHOD FOR CAST-IN-PLACE PILE

SATO SHINKO / ARAKAWA MAKOTO / MIZUMOTO MINORU

PROBLEM TO BE SOLVED: To provide a method that enables a hole with a diameter-enlarged part to be drilled on a narrow site.SOLUTION: In a drilling method for drilling a hole for constructing a cast-in-place pile, the hole is drilled in the ground by laterally emitting a jet of slurry and compressed air from a high-pressure injection nozzle 54 while rotating a rod 52 with the high-pressure injection nozzle 54 in the state of inserting the rod into the ground.SELECTED DRAWING: Figure 4

【課題】狭隘な敷地で拡径部を有する孔を掘削できる方法を提供する。【解決手段】場所打ち杭を構築するための孔を掘削する削孔方法であって、高圧噴射ノズル５４を有するロッド５２を地盤に挿入して回転させながら高圧噴射ノズル５４から安定液と圧縮空気とを横方向に噴射させることにより、地盤を削孔する。【選択図】図４
