PROBLEM TO BE SOLVED: To provide a pile with varying diameters that enhances adhesion between a foundation pile, or a pile and a ground after construction or installation, increases frictional force between the pile and the ground, functions sufficiently as a foundation to support a foundation part of a building, and curtails construction period necessary for installing the pile.SOLUTION: A pile with varying diameters 1 includes: a connection part 3 formed on an end 2, to be connected to a support post P and others; and an iron tubular pile body 10 having a part of which a diameter decreases from the end 2 toward the other end 4 and extending from the end 2 toward the other end 4. The pile with varying diameters 1 further includes at least one spiral recess 12 formed from the end 2 toward the other end 4 at least on an outer peripheral surface 11 of the pile body 10, the spiral recess spiraling in a same direction, and an inverse hook part 13 formed on the other end 4. The at least one recess 12 does not overlap in any part in an axial direction, and the inverse hook part 13 includes a plurality of blades 14 inclined by being warped toward the end 2 side.SELECTED DRAWING: Figure 1
【課題】工事後すなわち施工後の基礎杭すなわちパイルと地盤との密着性を高め、パイルと地盤との摩擦力を向上させて、建造物の基礎部分を支える基礎として十分に機能し、かつ、パイルの施工に要する工期を短縮できる異径パイルを提供することを目的とする。【解決手段】一端２に支柱Ｐ等に接続する接続部３と、一端２から他端４に向かって縮径する部分を含み、一端２から他端４に向かって延びる鉄製の管状のパイル本体１０と、を備えた異径パイル１において、少なくてもパイル本体１０の外周面１１に一端２から他端４に向かう回転方向が同方向である少なくても１本の螺旋状の凹部１２と、他端４に形成された逆鉤部１３と、を有し、少なくても１本の凹部１２は軸方向において重なる部分がなく、逆鉤部１３は一端２の側に反り返された勾配を有する複数枚の翼部１４を有する異径パイル１である。【選択図】 図１
