PURPOSE:To prevent the occurrence of noise pollution as well as make easier the confirmation of the bearing force of a steel pipe pile by a method in which a screwed ground-cutting, reinforcing metal tool is attached to the tip of a steel pipe, and the steel pipe with the metal tool is penetrated into the ground while being turned. CONSTITUTION:A screwed ground-cutting, reinforcing metal tool having a structure in which a spiral blade is provided to a metal cylinder 7 and the periphery of a conical metal tool is made smaller toward a pointed tip in a spirally and stepped manner is attached to the tip of a steel pipe 6. And, the steel pipe 6 with the metal tool is penetrated into the ground while being turned. Thus the steel pipe pile can be easily set. |
