摘要

To provide an installation method of a steel pipe pile capable of burying a steel pipe pile without using a large-sized heavy machine, and a steel pipe pile and an installation device used in the installation method.SOLUTION: An installation method of a steel pipe pile 10 includes a step of arranging a weight 21 for installation having a first weight 21A inside a first steel pipe pile 11 with a bottomed tip part 11A and repeating dropping of the weight 21 toward the bottomed tip part 11A so as to install the first steel pipe pile 11 into the foundation G. When the length of the steel pipe pile 10 to be installed in the foundation G is longer than that of the first steel pipe pile 11, the installation method includes a step of fixing the tip part of a second steel pipe pile 12 opening on both ends to a rear end part of the first steel pipe pile 11 so as to enlarge the entire length of the steel pipe pile 10 to be installed, and thus a necessary installation length can be obtained.SELECTED DRAWING: Figure 3
