CONSTRUCTION METHOD FOR OIL PROTECTIVE BARRIER
PROBLEM TO BE SOLVED: To propose a construction method for an oil protective barrier which is excellent in workability and economical efficiency.SOLUTION: A construction method for an oil protective barrier includes processes of: forming an inner form 21 by connecting a plurality of segments 2a, 2a, and so on in a ring shape on an upper surface of a bottom slab B; installing an outer form 3 on the outside of the inner form 21 with a clearance from the inner form 21; and placing concrete C between the inner form 21 and the outer form 3. The ring-shaped inner form 21 is configured to self-support, and the outer form 3 is connected via a separator 5 to the inner form 21, and lateral pressure when placing the concrete C acting on the outer form 3 is shared by the inner form 21.SELECTED DRAWING: Figure 3
【課題】施工性および経済性に優れた防液堤の構築方法を提案する。【解決手段】底版Bの上面で複数のセグメント2a,2a,…をリング状に連結して内型枠21を形成する工程と、内型枠21から隙間をあけて、当該内型枠21の外側に外型枠3を設置する工程と、内型枠21と外型枠3との間にコンクリートCを打設する工程とを備える防液堤の構築方法であって、リング状の内型枠21は自立しており、外型枠3はセパレータ5を介して内型枠21に連結し、外型枠3に作用するコンクリートCの打設時の側圧は内型枠21が受け持つ。【選択図】図3
