EARTH RETAINING WALL CONSTRUCTION METHOD, AND SOIL CEMENT CONTINUOUS WALL
To provide an earth retaining wall construction method capable of forming a soil cement continuous wall in which core materials are built only in necessary positions simply at low cost, and to provide a soil cement continuous wall.SOLUTION: An earth retaining wall construction method comprises: a drilling step of drilling a ground to form an excavation hole 4; and a core material building-in step of building a core material 3 into the excavation hole 4. In the drilling step, in-situ soil and a cement slurry are mixed and stirred to form soil cement 6 in the excavation hole 4. The core material building-in step performs: an insertion work of inserting the core material 3 to a predetermined depth or deeper using a plier 7 holding an upper end of the core material 3; an alternative receiving step of hanging the core material 3 by a cradle installed on the ground; and a pulling-out step of pulling the plier 7 out in a state where the core material 3 is hung.SELECTED DRAWING: Figure 3
【課題】簡易かつ安価に、必要な位置のみに芯材が建て込まれたソイルセメント連続壁を形成することを可能とした山留壁構築方法およびソイルセメント連続壁を提案する。【解決手段】地盤を削孔して掘削孔４を形成する削孔工程と、掘削孔４内に芯材３を建て込む芯材建込工程とを備える山留壁構築方法である。削孔工程では、掘削孔４内において原位置土とセメントスラリーとを混錬してソイルセメント６を生成する。芯材建込工程では、芯材３の上端部を保持するヤットコ７を利用して芯材３を所定の深さ以深に挿入する挿入作業と、地上に設置された架台で芯材３を吊持する受代え作業と、芯材３を吊持した状態でヤットコ７を引き抜く引抜作業とを行う。【選択図】図３
