CURING FORMWORK STRUCTURE AND CONSTRUCTION METHOD OF TUNNEL LINING
To propose a curing formwork structure and a construction method of tunnel lining which can start concrete placing work in other construction areas without waiting for the passage of curing period by a permeable formwork.SOLUTION: A curing formwork structure 7 comprises: a permeable formwork 3 added to a surface of concrete C; a formwork support material 8 for fixing the permeable formwork 3; and curing water supply means 9 for supplying curing water to the permeable formwork 3. The formwork support material 8 exerts a reaction force on the curing water supply means 9 and presses the permeable formwork 3 against the surface of the concrete C.SELECTED DRAWING: Figure 4
【課題】透水型枠による養生期間の経過を待たずに、他の工区におけるコンクリート打設作業を開始することが可能な養生型枠構造およびトンネル覆工体の施工方法を提案する。【解決手段】コンクリートＣの表面に添設された透水型枠３と、透水型枠３を固定する型枠支保材８と、透水型枠３に養生水を供給する養生水供給手段９とを備える養生型枠構造７であって、型枠支保材８は、養生水供給手段９に反力をとって透水型枠３をコンクリートＣの表面に押し付けている。【選択図】図４
