<p>PROBLEM TO BE SOLVED: To easily provide a foundation pile excellent in precipitation resistance and extraction resistance, by using a general purpose tool after implantation.SOLUTION: Bolt insertion members 41 and 45 are vertically provided in a pile body 101, and a bolt 50 is inserted. A pipe wall deformation member 60 capable of push-expanding a pipe wall 17 of he pile body to the outside by being compressively deformed vertically, is arranged, A nonrotating first nut member 71 is threadedly engaged with a screw between the pipe wall deformation member 60 and the lower bolt insertion member 45 among the bolt 50, and a similar second nut member 91 is also threadedly engaged with a lower screw part of the lower bolt insertion member 45. The pipe wall deformation member 60 is compressively deformed between the first nut member 71 and the upper bolt insertion member 41 by rotating the bolt 50 after implantation, and after push-expanding the pipe wall to the outside, the pipe wall 17 is vertically compressed between a second nut member 91 and the upper bolt insertion member 41, and is respectively threadedly engaged so as to increase deformation to the outside.</p> |
