CONSTRUCTION METHOD OF UNDERGROUND STRUCTURE AND UNDERGROUND STRUCTURE
To implement a reinforcing bar erection process that improves workability, safety, and quality using simple equipment.SOLUTION: A construction method of an underground structure is provided, and comprises a first excavation step of excavating the ground and forming a shaft, an earth retaining member installation step of installing an earth retaining member along a wall surface of the shaft, an initial reinforcing bar installing step of suspending and lowering the reinforcing bar into the shaft while fixing the horizontal position using a fixing jig attached to the earth retaining member, and a final excavation step in which the ground is further excavated and the shaft is excavated in the vertical direction, a final reinforcement step of suspending and lowering the reinforcing bar into the shaft excavated in the final excavation step while fixing the horizontal position using the fixing jig, and a concrete placing step of placing concrete inside the shaft including the reinforcing bars.SELECTED DRAWING: Figure 2
【課題】簡易な設備で施工性および安全性、ならびに品質を向上させた鉄筋の建て込み工程を実施する。【解決手段】地盤を掘削して立坑を形成する最初の掘削工程と、前記立坑の壁面に沿って土留部材を設置する土留部材設置工程と、前記土留部材に取り付けられた固定治具を用いて水平位置を固定しながら、前記立坑の内部に鉄筋を吊り降ろす最初の鉄筋建て込み工程と、前記地盤をさらに掘削して前記立坑を鉛直方向に掘り進める最後の掘削工程と、前記固定治具を用いて水平位置を固定しながら、前記最後の掘削工程で掘り進められた前記立坑の内部に前記鉄筋を吊り降ろす最後の鉄筋建て込み工程と、前記鉄筋を含む前記立坑の内部にコンクリートを打設するコンクリート打設工程とを含む、地中構造物の構築方法が提供される。【選択図】図２
