Nonflammable injectable grouting composition for backside water barrier and repairing crack of concrete structure and method for backside water barrier and repairing crack of concrete structure therewith
The present invention relates to a concrete structure rear order and crack repair and reinforcement simultaneous construction flame retardant injection composition and a concrete structure rear order and crack repair and reinforcement simultaneous construction method using the same. More specifically, according to the present invention, after a crack unit of a leaked part of a concrete structure of civil engineering and construction is perforated, it is injected into the back surface to absorb leakage and is filled with a flame-retardant acrylate-based elastic gelling agent which exhibits rapid gelation and elasticity to form a waterproof layer. Thereafter, a foam having elasticity and high strength is formed by reacting with a moisture remaining after being injected into a perforation and cracking unit of the leaked part. After that, parts which have not reacted with moisture are filled with flame-retardant high-strength foamed urethane which forms a cured product having elasticity and high strength by itself and cured to form a repair and reinforcing layer. Therefore, the concrete structure rear order and crack repair and reinforcement can be simultaneously constructed.
본 발명은 콘크리트 구조물 배면차수 및 균열보수보강 동시시공 난연주입제 조성물 및 이를 이용한 콘크리트 구조물 배면차수 및 균열보수보강 동시시공공법에 관한 것으로, 보다 상세하게는, 토목, 건축의 콘크리트 구조물의 누수부위의 균열부를 천공하고 배면에 주입하여 누수를 흡수하여 급결 겔화성 및 탄성을 나타내는 난연아크릴레이트계 탄성겔화 차수제를 채워 탄성겔화시켜 방수층을 형성한 후, 상기 누수부위 천공 및 균열부에 주입하여 남은 수분과 반응하여 탄성 및 고강도의 물성을 가지는 발포체를 형성하고, 수분과 반응하지 않은 부분은 자체적으로 탄성 및 고강도의 물성을 가지는 경화물을 형성하는 난연고강도발포우레탄을 채워 경화시켜 보수보강층을 형성하여 콘크리트 구조물의 배면차수 및 균열보수보강을 동시에 시공할 수 있는 콘크리트 구조물 배면차수 및 균열보수보강 동시시공 난연주입제 조성물 및 이를 이용한 콘크리트 구조물 배면차수 및 균열보수보강 동시시공공법에 관한 것이다.
