PRECAST PILE AND FOUNDATION PILE STRUCTURE
PROBLEM TO BE SOLVED: To provide a precast pile that may be handled easily at times of transportation and transferring, and that ensures unification of a pile body and a bulb section, as well as a foundation pile structure with the precast pile embedded in a pile hole.SOLUTION: A precast pile 10 comprises a concrete pile body 20 of a hollow tubular form and an irregularly-shaped inner wall part 30 formed at the bottom edge of an inner surface 22 of a void part 21 of the pile body. The irregularly-shaped inner wall part includes at least one of a recess 31 that is depressed toward outside in the radial direction from the inner surface and a protrusion that projects toward inside in the radial direction from the inner surface. A foundation pile structure 50 is formed by embedding the precast pile 10 into a pile hole 60 having a foot protection part 62. The foundation pile structure is buried with the irregularly-shaped inner wall part positioned at the foot protection part.
【課題】既製杭の搬送時、あるいは移動時における取り扱いが容易で、杭本体と球根部が確実に一体となる既製杭、および当該既製杭を杭穴内に埋設した基礎杭構造を提供する。【解決手段】既製杭10は、コンクリート製の中空筒形状を有する杭本体20と、杭本体における中空部21の内面22の下端部に形成された異形内壁部30と、を有する。異形内壁部は、内面から径方向外方に向けて窪んだ凹部31または内面から径方向内方に向けて突出する凸部を少なくとも1つ含んでいる。基礎杭構造50は、根固め部62を有する杭穴60内に上記の既製杭10を埋設して構成される。基礎杭構造にあっては、異形内壁部を根固め部に位置させて埋設されている。【選択図】図1
