METHOD FOR CONSTRUCTING PILE FOUNDATION AND PILE FOUNDATION
PROBLEM TO BE SOLVED: To provide a method for constructing a pile foundation that can secure pile end bearing capacity of a necessary minimum surely while facilitating excavation of a pile hole by avoiding excavation of a bearing layer; and a pile foundation.SOLUTION: A method for constructing a pile foundation comprises an excavation step of forming a pile hole in the foundation, a pile periphery fixing liquid filling step of filling the pile hole with a pile periphery fixing liquid, a foot protection liquid filling step of filling the lower end of the pile hole with a foot protection liquid, and a precast pile insertion step of inserting a precast pile in the pile hole. In the excavation step, excavation of a pile hole is stopped when excavation reaches a bearing layer in the foundation, and in the precast pile insertion step the lower end of the precast pile is brought into contact with the bearing layer and a foot protection liquid is cured in a state that the lower end of the precast pile is in contact with the bearing layer.SELECTED DRAWING: Figure 3
【課題】支持層の掘削を回避することにより杭孔の掘削を容易にしながら、必要最低限の杭先端支持力を確実に確保可能な杭基礎の構築方法及び杭基礎を提供する。【解決手段】杭基礎の構築方法は、地盤に杭孔を形成する掘削工程と、杭孔に杭周固定液を充填する杭周固定液充填工程と、杭孔の下端部に根固め液を充填する根固め液充填工程と、杭孔に既製杭を挿入する既製杭挿入工程と、を備え、掘削工程にて、地盤中の支持層に到達した時点で杭孔の掘削を停止し、既製杭挿入工程では、既製杭の下端を支持層に当接させ、既製杭の下端が支持層に当接した状態で根固め液を硬化させる。【選択図】 図３
