PROBLEM TO BE SOLVED: To provide a precast concrete pile having a structure capable of easily securing sufficient cross-sectional performance in a cross section near an end plate even when the standard end plate is used to a special wall type pile body.SOLUTION: A special wall pile 12A has a special wall type pile body 14 having a large wall thickness protruding to an inner side than a standard type pile body 13. An end plate 16 formed in a hollow shape having a size between the inner and outer diameters smaller than the wall thickness of the pile body 14 and having the same size as that of the standard type pile body is provided at an end face of the special wall type pile body 14. In the wall-specific pile 12A, a cylindrical steel plate 18 is provided over the outer peripheral surface of the pile body 14 from the end plate 16. The thickness of the steel plate 18 is determined such that a conversion cross sectional area at a cross section part B-B is equal to or more than a conversion cross sectional area at a cross section part A-A and a conversion geometrical moment of inertia at the cross section part B-B is equal to or more than a conversion geometrical moment of inertia at the cross section part A-A. |
