Abstract (en)
[origin: EP4101986A1] An object is to provide a steel pipe pile having multiple steps of blades and capable of most effectively exerting a supporting force. Another object is to provide a steel pipe pile that has blades with optimum thicknesses and/or fixture strengths and that can be manufactured with reduced costs.An open-end steel pipe pile 1 includes a pile body 3 composed of a steel pipe with an outer diameter of φ800 mm or less and a plurality steps of blades 5 fixed by welding to the pile body 3 to project from an outer periphery of the pile body 3, and a relationship of 10 ≤ h<sub>k</sub>/w<sub>k</sub> ≤ 30 (where k is an integer of 1 or more) is satisfied, where k is an integer of 1 or more, w<sub>k</sub> is a projecting length of a (k+1)<sup>th</sup> blade of the plurality steps of blades counted from bottom, and h<sub>k</sub> is an interval between the (k+1)<sup>th</sup> blade and another one of the plurality steps of blades that is downwardly adjacent to the (k+1)<sup>th</sup>.
