PROBLEM TO BE SOLVED: To provide a steel pipe pile structure that hardens sediment accumulated inside for certain when a steel pipe pile, including that with a large diameter, reaches a targeted bearing ground, thereby obtaining reactive force of the bearing ground and enlarging a bearing capacity of the steel pipe pile, for obtaining an ideal steel pipe pile.SOLUTION: A steel pipe pile structure that press-fits a steel pipe pile 1 into a targeted bearing ground J has an outer diameter enlarged to 1/10 of a length between a tip 11 of the steel pipe pile 1 that has reached the bearing ground J and a ground surface G, so as to lower a frictional resistance along an inner peripheral surface of the steel pipe pile 1 brought about by sediment D that comes inside, and a partition wall 2 installed that divides inside the steel pipe pile 1 into two parts in a vertical direction. The partition wall 2 is set at a location corresponding to a length L from the tip 11 of the steel pipe pile 1 that has reached the bearing ground J to the ground surface G. |
