METHOD FOR CONSTRUCTING PILE
To provide a method for constructing a pile which can appropriately form at least a peripheral surface grout and can efficiently use a flowable solidification material.SOLUTION: A method for constructing a pile that drives the pile into the ground using a plurality of injection nozzles attached near the tip of the pile and a vibration hammer attached to the upper end of the pile includes: an installation step of driving the pile into a driving end depth while imparting vibration thereto by the vibration hammer and injecting water thereto from the injection nozzles; and a peripheral surface grout treatment step of pulling up the injection nozzles to a peripheral surface grout upper end depth together with the pile and dropping the injection nozzles from the peripheral surface grout upper end depth while imparting vibration thereto by the vibration hammer after the installation step, and injecting a flowable solidification material from the injection nozzles at least during dropping from the peripheral surface grout upper end depth.SELECTED DRAWING: Figure 3
【課題】少なくとも周面グラウトを適切に形成できると共に流動性固化材を効率的に使用できる杭の施工方法を提供する。【解決手段】杭の先端近傍に取り付けられた複数の噴射ノズルと、前記杭の上端に取り付けられたバイブロハンマとを用いて前記杭を地盤に打ち込むための杭の施工方法において、前記バイブロハンマによる振動を与えかつ前記噴射ノズルから水を噴射しながら前記杭を打止め深度まで打ち込む打設工程と、前記打設工程の後、前記バイブロハンマによる振動を与えながら前記杭と共に前記噴射ノズルを周面グラウト上端深度まで引上げかつ前記周面グラウト上端深度から降下させ、少なくとも前記周面グラウト上端深度からの降下時に前記噴射ノズルから流動性固化材を注入する周面グラウト処理工程とを有することを特徴とする。【選択図】図3
