After that, the cap 1 or a tool 6 is turned in the right direction and is interlocked with one of the projections 4 of the right end cap 1 of the interlocking projections 9, the cap 1 is fitted to the pile head of the steel pipe pile P with a handle 8B, and it is pushed down and is fitted and fixed firmly. Then, the bar-shaped handle 8B is turned in the left direction and is pulled upward, and the interlocking projections 9 are separated from the projections 9 to remove.
