METHOD FOR CONSTRUCTING CORE MEMBER AND APPARATUS FOR CONSTRUCTING CORE MEMBER
PROBLEM TO BE SOLVED: To provide a method for constructing a core member and an apparatus for constructing a core member capable of precisely constructing a core member in a soil improvement body in an unconsolidated state using simple equipment.SOLUTION: An apparatus for constructing a core member comprises an air injection tube provided with an injection port for injecting compressed air in a horizontal direction which is arranged in a core member in a way that the injection port is positioned at a part lower than a lower end of the core member. A method for constructing a core member is configured to construct a core member in a soil improvement body in an unconsolidated state by being inserted into the soil improvement body with its dead weight while injecting compressed air from the injection port.SELECTED DRAWING: Figure 3
【課題】芯材を、未固結状態の地盤改良体に対して簡略な装備で精度よく建て込むことの可能な、芯材の建て込み方法および芯材建込装置を提供する。【解決手段】芯材に、水平方向に圧縮空気を噴射する噴射口を備えるエア噴射管を、前記噴射口が前記芯材の下端面より下方に位置するように設置し、前記噴射口より圧縮空気を噴射しつつ、未固結状態の前記地盤改良体に前記芯材を自重により挿入し建て込む。【選択図】図３
