PRECAST PILE AND SUPPORT METHOD OF PRECAST PILE
PROBLEM TO BE SOLVED: To provide a precast pile and a support method of precast pile capable of stably supporting the precast pile in place when installing a large diameter and heavy precast pile in a pile hole at construction site.SOLUTION: A precast pile 10 to be installed in a pile hole includes: a pile body 12 having a generally circular column shape or generally cylindrical shape; and an annular convex part 18 which is integrally formed in an annular shape along the outer peripheral surface 12c of the pile body and has a contiguous face the diameter of which gradually increases in a direction of one end part 12a of the pile body from a predetermined point of the outer peripheral surface. The annular convex part includes: a tapered plane 14 the diameter of which increases at a constant ratio in a direction from a predetermined point of the outer peripheral surface to one end part; and another tapered plane 16 the diameter of which reduces in a direction from the apex 14a of the tapered plane to the one end part.
【課題】大径化に伴い重量化が進む既製杭を施工現場の杭孔に建て込む際に、当該既製杭をより確実に定位置で安定させて支持する既製杭、及び既製杭の支持方式を提供する。【解決手段】杭孔に建て込まれる既製杭１０であって、略円柱形状又は略円筒形状の杭本体１２と、杭本体の外周面１２ｃに沿って環状に一体成型され、当該外周面の所定の位置から杭本体の一端部１２ａを有する方向に拡径して形成される連続面が設けられる環状凸部１８と、を備えており、環状凸部は、外周面の所定の位置から一端部を有する方向に一定の割合で拡径して形成されるテーパ面１４と、当該テーパ面の頂部１４ａから一端部を有する方向に縮径して形成される他のテーパ面１６とを有することを特徴とする。【選択図】図１
