<p>Disclosed is a foundation pile group that is configured from foundation piles that can reliably support the total bearing capacity required and of which the construction is easy. The foundation pile group (10) is configured from a plurality of foundation piles (1a, 1b, 1c, 1d), is installed in the ground (90), and supports a structure (80). The foundation piles (1a, 1b, 1c, 1d) are each equipped with: a steel pipe (the same as the pile bodies) (2a, 2b, 2c, 2d); and a helical vane (3a, 3b, 3c, 3d) that is nearly helical and that is affixed to end or the vicinity of the end of the steel pipe (2a, 2b, 2c, 2d). Also, the outer diameters of the helical vanes (3a, 3b, 3c, 3d) are formed nearly equally.</p> |
