SQUARE COLUMNAR PILE
PROBLEM TO BE SOLVED: To provide a square columnar pile that is easy to bury underground.SOLUTION: A square columnar pile 11 including a through hole 11a into which an auger screw can be inserted has a cutting part 12 having a triangular cutting surface 12a at a corner part of the square columnar pile's bottom surface. Arranging one vertex 12b of the cutting surface 12a downward to make the cutting surface 12a's posture tilt from the one vertex 12b to the through hole 11a enables the cutting part 12 to cut an excavation hole antecedently excavated by the auger screw so that the excavation hole is extended to the size of a square columnar pile 10's bottom surface, thereby making it possible to easily bury the square columnar pile 10 underground.SELECTED DRAWING: Figure 1
【課題】地中に埋設しやすい四角柱状杭を提供する。【解決手段】オーガスクリューを挿通可能な貫通穴１１ａを有する四角柱状杭１１の底面の角部に、三角形状の切削面１２ａを有する切削部１２を設け、その切削面１２ａの一頂点１２ｂを下方に向けて配して、切削面１２ａが一頂点１２ｂから貫通穴１１ａへ向かって傾斜する姿勢とすれば、オーガスクリューが先行掘削した掘削穴を、切削部１２によって四角柱状杭１０の底面のサイズに広げるように切削することができるので、四角柱状杭１０を容易に地中に埋設することが可能になる。【選択図】図１
