To provide a steel pipe pile, which is used for reinforcing the ground or a foundation of a structure and modifying an inclination of an existing foundation and can be pressed into the ground while injecting mortar therein, capable of being easily constructed, achieving a large reinforcement effect and reducing a manufacturing cost.
A steel pipe pile 10 comprises: a cylindrical main body 1; a first helical blade 21 which is arranged close to a tip 1A (a lower edge when constructed) of the main body and used for screwing; a second helical blade 22 which is arranged at a posterior portion of the main body with a helical pitch smaller than that of the first helical blade; discharge holes 11 which are arranged inside a region of the first helical blade; and a bead section 23 which is arranged between the first helical blade and the second helical blade and wound in an opposite helical direction thereto.
