PROBLEM TO BE SOLVED: To provide a construction method of steel pipe sheet pile well ocean foundation and a steel pipe sheet pile well ocean foundation that can be constructed with a simplified facility and can reduce material cost and construction cost compared to a mono-pile foundation having a large diameter.SOLUTION: A partition plate 65 and a reinforcing bar cage 31 are installed in an interior 69 of a steel pipe sheet pile well 3 and concrete 33 is cast, after the steel pipe sheet pile well 3 is driven into a water bottom 43, mortar 41 is filled in a joint portion 17 between steel pipes 11, and water in an interior 69 of the steel pipe sheet pile well 3 is discharged. Next, an intermediate joint portion 5 is hung down on the steel pipe sheet pile well 3 and a lower portion of each steel pipe 11 constituting a leg portion 7 of the intermediate joint portion 5 is inserted into an upper portion of each steel pipe 9 constituting the steel pipe sheet pile well 3. Thereafter, grout 27 is injected into a gap 77 between an inner peripheral surface 19 of each steel pipe 9 constituting the steel pipe sheet pile well 3 and an outer peripheral surface 25 of each steel pipe 11 constituting the leg portion 7 of the intermediate joint portion 5, and the steel pipe sheet pile well 3 and the intermediate joint portion 5 are fixed.SELECTED DRAWING: Figure 2
