PROBLEM TO BE SOLVED: To provide a method for using a diameter-enlarged pipe pile, which facilitates the selection of the effective sectional area of the leading end of the pile by substituting a different-diameter pipe for a part of a rotary penetration pile for use in the construction of a foundation and the strengthening of ground.;SOLUTION: The rotary penetration pile is split into a leading end 12 and a supplementary part 19. At the leading end 12, a spiral vane 18 is attached to the side of an enlarged diameter 14 of the different-diameter pipe 13, and an excavating blade 17 is provided according to need. A pipe 20 with a required length, which is equal in diameter to the side of a reduced diameter 16 of the pipe 13, is connected to the supplementary part 19. After the diameter-enlarged pipe pile 11, wherein both the parts are connected together for integration, penetrates into the required ground, structures on the land are directly or indirectly connected to a pile head part 21 so that the foundation can be constructed of a metal, and the diameter-enlarged pipe pile is made to penetrate into the required ground. After that, the ground corresponding to the pile head part 21 is fixed, and the ground is strengthened by making either or both of a bearing capacity and a tensile force occur on the pile.;COPYRIGHT: (C)2006,JPO&NCIPI
