FOUNDATION PILE, CONSTRUCTION METHOD THEREFOR, AND BRIDGE
PROBLEM TO BE SOLVED: To provide a foundation pile and a construction method therefor that increase vertical bearing force and horizontal reaction even with a poor ground, reduce the number, diameter and length of the pile, and may be constructed in a short construction period at a low cost.SOLUTION: A foundation pile 3 includes a tubular body 1 buried underground excluding a head part, and a bevel-shaped member 2 having an opening that pierces through the tubular body 1 and is buried near a ground surface. More specifically, the bevel-shaped member 2 has an opening in a central part, as well as an outer wall surface 21 almost parallel with an outer peripheral surface of the tubular body 1, an inclined wall surface 22 inclined toward the opening from an upper part of the outer wall surface 21, and a collar part 23 protruding upward along the opening from an upper part of the inclined wall surface 22 and having an inner diameter slightly larger than an outer diameter of the tubular body 1. The tubular body 1 and the bevel-shaped member 2 are integrated after installing the tubular body 1 and inserting the tubular body 1 through the opening of the bevel-shaped member 2 and then installing the bevel-shaped member 2 near the ground surface.SELECTED DRAWING: Figure 1
【課題】軟弱地盤であっても鉛直支持力、水平反力を増大でき、杭本数、杭径、杭長を減らし、省面積で、短い工期、低コストで構築可能な基礎杭と、その施工方法を提供する。【解決手段】頭部を残して地中に埋設される筒状体１と、その筒状体１を挿通する開口を有し、地表近傍に埋設される笠状部材２と、からなる基礎杭３。具体的には、笠状部材２は、中央部に開口を有し、筒状体１の外周面に略平行な外壁面２１と、その外壁面２１の上部から開口に向かう斜壁面２２と、その斜壁面２２の上部から開口に沿って上方に突出され、筒状体１の外径より僅かに大きい内径を有するカラー部２３と、を備える。そして、筒状体１を地盤に打設し、笠状部材２の開口に筒状体１を挿通させて、笠状部材２を地表近傍に打設してから、筒状体１と笠状部材２とを一体化させる。【選択図】図１
