ROTATION BURIED PILE AND EXECUTION MANAGEMENT METHOD THEREFOR

摘要

A rotation buried end-opened pile capable of being easily penetration-driven due to a reduced apparent tip end resistance when a ground strength increases rapidly and providing a large final bearing capacity, comprising a pile body having an opened tip end and consisting of a steel pipe or a non-steel hollow pipe and one or a plurality of blades provided on the outer side face of the tip end of the pile body, wherein the tip ends of the blades may project downward beyond the tip end face of the pile body. An execution management method for a rotation pressed-in pile having one or a plurality of blades on the outer side face of the lower end thereof, characterized in that the continued penetration and/or the penetration completion of the rotation pressed-in pile are controlled, at the execution, according to a penetration resistance (Rp) at a bottom plate which is being determined from a balance between an input energy applied to a pile head and an energy consumption released at the bottom plate.
