The invention provides a screw-in type steel pipe pile, a design method, a manufacturing method, and a construction method. Construction suitable for a form of a foundation such as a soft foundation or a hard foundation can be performed without adverse influence on a supporting force. A screw-in type steel pipe pile (1) in which two or more arc-shaped rotating blades (3) are provided continuously in the circumferential direction at the tip of a steel pipe (2), the rotating blades (3) being formed by dividing a disc or an annular disc having a larger outer diameter than the steel pipe (2) in the radial direction. Among the rotating blades (3), the mounting angle of a lowermost blade (3a), which is the lowermost rotating blade (3) disposed on the steel pipe (2), is smaller than the mounting angle of an uppermost blade (3b), which is the uppermost rotating blade (3) disposed on the uppermost.
本发明提供一种拧入式钢管桩、设计方法、制造方法和施工方法，能够不会对支承力产生恶劣影响地进行适合于柔软的地基、硬的地基等地基的形态的施工。本发明所涉及的拧入式钢管桩（1）在钢管（2）的前端沿周向连续设置有两片以上的圆弧状的旋转叶片（3），该旋转叶片（3）是将比钢管（2）的外径大的圆盘或环状的圆盘沿径向分割而成的旋转叶片，旋转叶片（3）中的配置于钢管（2）的最下方的旋转叶片（3）即最下方叶片（3a）的安装角度比配置于最上方的旋转叶片（3）即最上方叶片（3b）的安装角度小。
