Abstract
The purpose of the present invention is to provide a steel pipe pile having blades in multiple stages and capable of exhibiting most effective supporting force. Another purpose of the present invention is to provide a steel pipe pile in which the thickness and/or attachment strength of blades are optimized and which makes it possible to reduce manufacturing costs. An open-end steel pipe pile 1 comprises a pile main body 3 comprising a steel pipe with an outer diameterf of 800 mm or less, and multistage blades 5 welded and fixed so as to project from an outer circumference of the pile main body 3, the steel pipe pile 1 satisfying the relationship 10 = hk/wk = 30 (where k is an integer greater than or equal to 1), wherein wk is the projecting length of each blade in a (k + 1)th stage from the bottom among multistage blades 50 to 53, and hk is the spacing between each blade and the blade of a stage below.
