REPAIR STRUCTURE FOR CONCRETE STRUCTURE, AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a repair structure for a concrete structure that is low in construction costs and high in work efficiency, ensuring water cut-off even when an injection hole does not cross a crack or when there is a large void on a rear surface of concrete.SOLUTION: A repair structure for a concrete structure comprises in an area subject to water cut-off on lining concrete 2: a plurality of non-penetrating injection holes 6 formed leaving an interval in the area subject to water cut-off, from a front surface side of the lining concrete 2; and water cut-off parts 8a, 8b, 9a, 9b, 10 formed to almost fill each of the injection holes 6, and to spread from each of the injection holes 6 as starting points to infiltrate into a minute gap in the lining concrete 2. The water cut-off part is formed of a water cut-off material containing a base compound having viscosity of 5 mPa s or less.SELECTED DRAWING: Figure 2
【課題】注入孔がひび割れを横断しない場合やコンクリートの背面に大きな空洞がある場合でも確実に止水することができると共に、施工コストが低く、施工効率に優れるコンクリート構造物の補修構造を提供する。【解決手段】覆工コンクリート２の止水対象領域に、覆工コンクリート２の表面側から非貫通で形成され、止水対象領域に間隔を開けて複数設けられる注入孔６と、注入孔６の各々に略充填するように設けられ、且つ注入孔６の各々を起点として拡散し覆工コンクリート２の微小空隙に浸透するように設けられる止水部８ａ、８ｂ、９ａ、９ｂ、１０とを備え、この止水部が、粘度５ｍＰａ・ｓ以下の主剤から構成される止水材によって形成されているコンクリート構造物の補修構造。【選択図】図２
