CONSTRUCTION METHOD OF UNDERGROUND STRUCTURE AND UNDERGROUND STRUCTURE AS WELL AS PRECAST CONCRETE SIDE WALL OR INTERMEDIATE WALL/COLUMN THEREFOR
To provide a construction method of an underground structure allowing cost to be reduced and usability to be expanded by making a precast concrete side wall thinner and preventing damage of the precast concrete side wall even upon large overburden.SOLUTION: A construction method comprises steps of: at construction sites on both side wall parts, installing a precast concrete side wall 2 to be a body structure in the ground, in which steel material 5 is placed as core material in place of main reinforcement as well as soil retention steel material 5B is formed for resistance in a lateral direction against soil-water pressure and the like by extending the steel material 5 upward from an upper end surface; constructing a top cap 3 to be a body part between the precast concrete side walls 2, 2 after excavating and removing the ground down to a position where the top cap between the precast concrete side walls 2, 2; and finishing a shallower part of the top cap through refilling therein in advance.SELECTED DRAWING: Figure 3
【課題】プレキャストコンクリート側壁の薄型化を図ることで、コスト縮減及び適用性の拡大を図るとともに、土被りが大きい場合でもプレキャストコンクリート側壁の破損を防止する。【解決手段】両側壁部の構築部位に、主筋の代わりに鋼材５が芯材として配置されるとともに、前記鋼材５が上端面より上方側に延出して土水圧などの側方抵抗のための土留め壁用鋼材部５Ｂを形成した、本体構造となるプレキャストコンクリート側壁２を地中に建込み、これらプレキャストコンクリート側壁２、２間の頂版を構築する位置までの地盤を掘削除去した後、前記プレキャストコンクリート側壁２、２間に本体構造となる頂版部３を構築し、埋め戻すことにより頂版部以浅部分を先行的に完成させる。【選択図】図３
