摘要： A steel pipe pile provided with: a straight section having a cylindrical shape; and a tapered section continuing to one end of the straight section and having an outer diameter and an inner diameter which are reduced in the direction away from said end. The diameter-distance ratio (H1/D1) obtained by dividing the distance (H1) between the large end and the small end of the tapered section by the outer diameter (D1) at the large end is not less than 0.1 but not greater than 2.5.

摘要： A joint structure for a steel pipe pile in which a first steel pipe pile having an outer fitting end part and a second steel pipe pile having an inner fitting end part are coupled while the outer fitting end and the inner fitting end share the same axis center line, wherein when viewed in cross-section along the axis center line, outer fitting step parts (or inner fitting step parts) are provided at multiple positions along the axis center line on the inner side (or the outer side) of the outer fitting end part (or the inner fitting end part), so as to gradually increase (or decrease) in diameter toward the second steel pipe pile (or the first steel pipe pile); each outer fitting step part (or inner fitting step part) has an outer fitting crest part (or inner fitting crest part) relatively near the second steel pipe pile (or the first steel pipe pile), and an outer fitting root part (or inner fitting root part) adjacent to the outer fitting crest part (or inner fitting crest part); and the ratio obtained by dividing the plate thickness at the outer fitting root part nearest to the second steel pipe pile by the plate thickness of the inner fitting root part nearest to the first steel pipe pile is 0.84 or more.
