Abstract

PURPOSE: To keep a steel tubular pile from negative circumferential friction by a method in which a taper is provided to a steel tubular pile itself in such a way that the pile is separated from its adjoining ground as the ground settles.
CONSTITUTION: In case where after a tapered steel tubular pile 3 is driven through soft dlay layer 4 to support substratum 5, the ground 6 is somehow lowered to the level 7 of the ground settled, the contact face 8 between the tapered steel tubular pile 3 and the clay layer 4 is lowered to the level of a settled contact face 9 as the ground settles, whereby the tapered steel tubular pile 3 is separated from the clay layer 4 to prevent the occurrence of negative circumferential friction.
