METHOD OF CONSTRUCTING UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a method of constructing an underground structure that can largely shorten the construction period and reduces the construction cost without using a precast member.SOLUTION: A part of an upper ground 1 between continuous underground walls 11a and 11b is excavated and a short strut 17 is installed. Next, the upper ground 1 between the continuous underground walls 11a and 11b is excavated to a predetermined depth and is excavated, for example, to a depth permitting installation of a form of a pile cap. The short strut 17 may be one that can resist an earth pressure up to the depth. An upper surface of an excavated part is smoothly finished and is rolled so as not to settle, and crushed stones are laid and leveled. Next, sand is evenly laid on the surface and leveled, and a form 19 is installed. Next, a reinforcement 22 is assembled on the form 19. Concrete is also placed so as to fill up the reinforcement 22, and a pile cap 21 is formed on the ground between the pair of continuous underground walls 11a and 11b.SELECTED DRAWING: Figure 10
【課題】 プレキャスト部材を用いることなく、大幅な工期短縮と工費削減を図れる地下構造体の構築方法を提供する。【解決手段】連続地中壁１１ａ、１１ｂ間の上部の地盤１の一部を掘削し、切梁１７を設置する。次に、連続地中壁１１ａ、１１ｂ間の上部の地盤１を、所定深さまで掘削する。例えば、頂版の型枠が設置可能な深さまで掘削する。なお、切梁１７は、この深さまでの土圧に耐えられるものでよい。掘削部の上面は平滑に仕上げられて沈下しないように転圧され、砕石が敷均される。次に、砂を表面に敷均して平滑にし、型枠１９が設置される。次に、型枠１９上に、鉄筋２２を組み立てる。さらに、鉄筋２２が埋まるようにコンクリートを打設し、一対の連続地中壁１１ａ、１１ｂの間の地盤上に頂版２１を形成する。【選択図】図１０
