description | PROBLEM TO BE SOLVED: To reduce manufacturing and execution cost by eliminating the need of working for a connecting means such as a joint member or a diameter enlarged part for pile connection to facilitate connection in a foundation pile. SOLUTION: A pile body 43 formed as a cylindrical straight pipe with a predetermined length, a lower end part 48 as a fourth joint part formed on the cylindrical straight pipe with the same diameter as the pile body 43, a large diameter part 41 as a cylindrical third joint part and a connecting part 42 connecting the large-diameter part 41 and the pile body 43 are integrally formed by casting. The connecting part 42 is so constructed that the above-ground side end part is formed integral with the ground end part of the large-diameter part 41, the outer peripheral surface is a tapered surface, and a step part 45 is formed in the vicinity of the ground end part of the large-diameter part 41 by a difference in size between the inside diameter of the connecting part 42 and the inside diameter of the large-diameter part 41. Further, a plurality of through holes 44, 46 are formed in the peripheral surfaces of the large diameter part 41 as the third joint part and the lower end part 48 as the fourth joint part, and a connector 70 is inserted in the through holes 44, 46 to connect another pile member constituting the cast pile.
