PROBLEM TO BE SOLVED: To provide a precast pile that may be handled easily at times of transportation and transferring, and that ensures unification of a pile body and a bulb section, as well as a foundation pile structure with the precast pile embedded in a pile hole.SOLUTION: A precast pile 10 comprises a concrete pile body 20 of a hollow tubular form and an irregularly-shaped inner wall part 30 formed at the bottom edge of an inner surface 22 of a void part 21 of the pile body. The irregularly-shaped inner wall part includes at least one of a recess 31 that is depressed toward outside in the radial direction from the inner surface and a protrusion that projects toward inside in the radial direction from the inner surface. A foundation pile structure 50 is formed by embedding the precast pile 10 into a pile hole 60 having a foot protection part 62. The foundation pile structure is buried with the irregularly-shaped inner wall part positioned at the foot protection part. |
