CONSTRUCTION METHOD USING TEMPORARY SCAFFOLD
To provide a construction method for a temporary scaffold that can be applied to structures whose horizontal projection area is smaller at the upper parts than that at the lower parts, and that can reduce the number of assembly and removal steps to shorten the construction period.SOLUTION: A construction method using a temporary scaffold 1 which constructs a structure within a space surrounded by a temporary earth-retaining wall (steel sheet piles) comprises: a lower structure construction process of constructing a lower part (a caisson foundation CF) of the structure; a scaffold assembly process of installing a cradle 2 by combining steel materials 20 in parallel crosses on the lower part of the structure constructed in the lower structure construction process and assembling the temporary scaffold 1 on the cradle 2; an upper structure construction process of constructing an upper part (a bridge pier P1) of the structure using the temporary scaffold 1 assembled in the scaffold assembly process; a subsidence process of sinking the constructed structure C1; and a backfilling process of filling back sediment around the sunken structure.SELECTED DRAWING: Figure 6
【課題】構造物の水平投影面積が上部の方が小さくなるような構造物にも適用でき、組立撤去回数を低減して工期を短縮できる仮設足場の施工方法を提供する。【解決手段】仮設土留壁（鋼矢板）で囲われた空間内で構造物を構築する仮設足場１を用いた施工方法において、構造物の下部（ケーソン基礎ＣＦ）を構築する構造物下部構築工程と、前記構造物下部構築工程で構築した構造物下部の上に鋼材２０を井桁状に組み合わせて架台２を設置し、その架台２の上に仮設足場１を組み立てる足場組立工程と、前記足場組立工程で組み立てた仮設足場１を用いて前記構造物の上部（橋脚Ｐ１）を構築する構造物上部構築工程と、構築した構造物Ｃ１を沈下させる沈下工程と、沈下した構造物の周りに土砂を埋め戻す埋戻工程とを備える。【選択図】図６
