METHOD OF CONSTRUCTING BARRIER WALL
To ensure that a lower end of a barrier wall is placed into a hardly permeable layer.SOLUTION: A method of constructing a barrier wall includes a drilling step in which a drilling machine 20 is used to drill into ground 10 while pumping drilling water, and a drilling hole 30 is made to reach a hardly permeable layer 10X of the ground 10 based on the drilling data obtained during drilling, and an injection material injection step in which an injection material is injected into the drilling hole 30 to form a ground improvement body 42 in the ground 10. The drilling step and the injection material injection step are repeated to form a barrier wall 40 by making the ground improvement body 42 continuous in the form of a wall.SELECTED DRAWING: Figure 1
【課題】本発明は、遮水壁の下端部を難透水層により確実に根入れすることを目的とする。【解決手段】遮水壁の構築方法は、削孔機２０を用いて削孔水を送水しながら地盤１０を削孔し、削孔中に取得する削孔データに基づいて地盤１０の難透水層１０Ｘに削孔３０を到達させる削孔工程と、削孔３０に注入材を注入し、地盤１０に地盤改良体４２を形成する注入材注入工程と、を備え、削孔工程と注入材注入工程とを繰り返し、地盤改良体４２を壁状に連続させることで遮水壁４０を形成する。【選択図】図１
