PROBLEM TO BE SOLVED: To provide a foundation pile structure that has equal bearing power even if forming a narrow bottom part in the lower part of a foot protection part, and thereby can exhibit the bearing power efficiently.SOLUTION: A foundation pile structure 20 is made by disposing a concrete prefabricated pile 1 in a pile hole 10 by excavating the pile hole 10 to the supporting soil. The prefabricated pile 1 has a main structure for supporting a ground structure and exhibiting necessary strength, forms ribs 3 over the entire length, and has the maximum diameter of the lower end to be Din diameter. The pile hole 10 has a foot protection part 12 in a depth position corresponding to the supporting soil. The foot protection part 12 comprises a foot protection body 13 and a narrow bottom part 15. A lower end of the foot protection body 13 is made into diameter of D, and a narrow bottom part 15 having a predetermined length His continuously formed in diameter of D(D
【課題】根固め部の下部に狭底部を形成しても同等の支持力を有し、効率的に支持力を発揮できる基礎杭構造を実現できる。【解決手段】支持地盤まで杭穴１０を掘削して、杭穴１０内に、コンクリート製の既製杭１を配置して基礎杭構造２０とする。既製杭１は、地上構造物を支持し必要な強度を発揮するの主構造を有し、全長にわたりリブ３を形成し、下端部の最大径を径Ｄ０１とする。杭穴１０は支持地盤に対応した深さ位置に根固め部１２を有し、根固め部１２は根固め部本体１３と狭底部１５とかなり、根固め部本体１３の下端部を径Ｄ１１とし、根固め部本体１３の下端に連続して、径Ｄ１２（Ｄ０１＜Ｄ１２＜Ｄ１１）で所定長さＨ２を有する狭底部１５を形成する。既製杭１の主構造の下端部を、狭底部１５内に配置する。狭底部１５を含めた根固め部１２の側壁面及び底面と、既製杭１の外側面及び底面との間隙に、根固め液を充填して固化根固め液層２３を形成する。【選択図】図１
