METHOD FOR REMOVING EARTH RETAINING MEMBER
PROBLEM TO BE SOLVED: To provide a method for reducing the number of installed insertion pipes, and shortening the time taken in removal of an earth retaining member and reducing construction cost.SOLUTION: A method for removing an earth retaining member comprises the steps of: handling five or more earth retaining members continuously provided as one block, inserting an injection pipe next to or in the neighborhood of an earth retaining member located in the center of the block and installing the injection pipe in the foundation without fixing to the earth retaining member; and making an injection material flow from the injection pipe each time an earth retaining member in the block is pulled up at a certain height one by one in succession and making the injection material flow into a cavity formed in the foundation so as to fill the cavity.SELECTED DRAWING: Figure 5
【課題】 挿入管を設置する本数を減らし、土留部材の撤去にかかる時間を短縮し、施工コストを削減することができる方法を提供する。【解決手段】 この方法は、連設された５以上の土留部材を１つのブロックとし、ブロックの中央に位置する土留部材に隣接または近隣して注入管を挿入し、該土留部材に固定することなく地盤内に設置する工程と、ブロック内の土留部材を１つずつ順に一定高さ引き上げる毎に注入管から注入材を流出させて、地盤内に発生した空隙に該注入材を流入させ、該空隙を埋める工程とを含む。【選択図】 図５
