CONSTRUCTION METHOD OF OIL PROTECTIVE BARRIER
PROBLEM TO BE SOLVED: To propose a construction method of an oil protective barrier excellent in workability and economical efficiency.SOLUTION: A construction method of an oil protective barrier comprises a process of forming an inner form 21 by connecting a plurality of segments 2a, 2a, etc. in a ring shape on an upper surface of a bottom slab B, a process of installing an outer form 3 on the outside of the inner form 21 with a clearance from the inner form 21 and a process of placing concrete C between the inner form 21 and the outer form 3, and the ring-shaped inner form 21 self-supports, and the outer form 3 is connected to the inner form 21 via a separator 5, and lateral pressure when placing the concrete C acting on the outer form 3, is shared by the inner form 21.
【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
