RECONSTRUCTION METHOD

To provide a reconstruction method capable of shortening a construction period.SOLUTION: A lower part 10L of an old structure 10, which is a part at and below a prescribed height, is surrounded by a wall W of a temporary tent until an upper part of the old structure 10, which is a part at and above the prescribed height, is completely dismantled from the top. Then, the temporary tent is completed by making a roof atop the wall W. Inside the temporary tent, underground construction is performed including dismantling the lower part 10L of the old structure and dismantling an underground structure of the old structure 10.SELECTED DRAWING: Figure 5 【課題】工期の短縮を実現することのできる建て替え工法を提供する。【解決手段】旧構造物１０の上から所定の高さ以上の部分である高層部を解体し終わるまでに、旧構造物１０の所定の高さ以下の部分である低層部１０Ｌを、仮設テントの壁Ｗで囲う。次いで、壁Ｗの上に屋根を作ることで仮設テントを完成させる。仮設テントの内部で、旧構造物の低層部１０Ｌの解体と、旧構造物１０の地下の構造体の解体を含める地下工事とを実行する。【選択図】図５
