CONSTRUCTION METHOD FOR CONCRETE SKELETON AND UNDERGROUND STRUCTURE
To provide a construction method for a concrete skeleton capable of greatly improving workability when a cast-in-place concrete skeleton is constructed in the ground, and an underground structure.SOLUTION: A construction method for a concrete skeleton 1 for providing a cast-in-place concrete skeleton in the ground includes: a step of establishing a soil cement diagonal earth retaining wall 2 that is inclined in a direction separated from the concrete skeleton with respect to a vertical direction and is self-supportable, along an outer shape of the concrete skeleton that is planned to be constructed in plan view; a step of excavating the ground on the side of a construction region of the concrete skeleton to a predetermined depth when be viewed from the diagonal earth retaining wall; a step of installing a reinforcing material constituting an outer wall of the concrete skeleton at a predetermined position, and installing an inner form; and a step of filling the space between the inner form and the diagonal earth retaining wall sandwiching the reinforcing material with concrete, and constructing a plain concrete overhang member 3 arranged between the outer wall 12 and the diagonal earth retaining wall so as to be integral with the outer wall.SELECTED DRAWING: Figure 2
【課題】地盤中に現場打ちのコンクリート躯体を構築する際の施工性が大幅に向上するコンクリート躯体の構築方法、及び地中構造物を提供する。【解決手段】地盤中に現場打ちのコンクリート躯体を設けるためのコンクリート躯体１の構築方法であって、鉛直方向に対してコンクリート躯体から離間する方向に傾斜させた自立可能なソイルセメント造の斜め土留め壁２を、平面視で構築予定のコンクリート躯体の外形形状に沿って造成する工程と、斜め土留め壁からみて、コンクリート躯体の構築領域側の地盤を所定深さまで掘削する工程と、コンクリート躯体の外壁を構成する補強材を所定位置に設置するとともに内型枠を設置する工程と、補強材を挟んだ内型枠と斜め土留め壁との間をコンクリートで充填し、外壁１２と斜め土留め壁との間に配置される無筋コンクリート造の張出し部材３を、外壁と一体となるよう同時に構築する工程と、を備える。【選択図】図２
