CONCRETE STRUCTURE CONSTRUCTION METHOD AND CONCRETE STRUCTURE
To provide a concrete structure construction method capable of minimizing construction sites on a land and improving workability and safety during on-water construction when concrete members are joined together from multiple directions on water, and a concrete structure.SOLUTION: This concrete structure construction method comprises: the preceding arrangement step S2 of supplying ballast water into a first unit box body to arrange it at a prescribed position; and the joining step S4 of joining a second unit box body to the first unit box body. In the joining step S4, an operation for forming a joining space surrounded by a cut-off panel and the outer surfaces of the unit box bodies between the unit box bodies, an operation for draining water from the joining space, an operation for installing a cement material into the joining space to form a joined part, and an operation for integrating the unit box bodies and the joined part are carried out.SELECTED DRAWING: Figure 3
【課題】水上において多方向からコンクリート部材同士を接合する場合において、陸上における製作用の用地を最小限にし、かつ、水上施工における施工性と安全性の向上を可能としたコンクリート構造物の構築方法およびコンクリート構造物を提案する。【解決手段】第一のユニット函体内にバラスト水を供給して所定の位置に配設する先行配設工程Ｓ２と、第一のユニット函体に第二のユニット函体を接合する接合工程Ｓ４とを備えている。接合工程Ｓ４では、止水パネルとユニット函体同士の外面とにより囲まれた接合空間をユニット函体同士の間に形成する作業と、接合空間内の水を排水する作業と、接合空間内にセメント系材料を打設して接合部を形成する作業と、ユニット函体と接合部とを一体化する作業とを行う。【選択図】図３
