Embedded pile for steel pipe pile

摘要

PROBLEM TO BE SOLVED: To provide a bored steel pipe pile formed with multi-stage projecting parts capable of suppressing local buckling generated by the unbalanced sharing of dislocation stop yield strength, by efficiently exhibiting a dislocation stop function in the steel pipe pile for a bored pile.;SOLUTION: The tip part outer peripheral surface of this steel pipe pile buried in the ground by a bored pile construction method is provided with two or more stages of projecting parts projected beforehand by the diameter enlarging deformation of a steel pipe, and two or more stages of projecting parts are constituted to have different shapes to improve axial yield strength by changing or combining heights, radii or lengths of projections.;COPYRIGHT: (C)2004,JPO
