Abstract

In this research, we tried to investigate the influence of concrete on cracks after applying to the actual construction site using the TPS construction method which can be easily charged by the mechanical injection method. To summarize the results, the following It is as follows. First, in the case of ultrasonic velocity, it can be seen that the ultrasonic wave passes rapidly at an average of about 36 mm / sec as compared with the syringe method when using the TPS method, and in the case of the injection depth, the syringe method In the case of TPS construction method, it showed an excellent tendency that 100% of the water retentive material was charged with all the formulations under a strong injection pressure. In the case of compressive strength, it was shown that the average was increased by 16.8% at the time of using the TPS construction method, and it was found to be structurally superior. Taken together, it is possible to confirm the behavior of the crack repairing agent by improving the quality by improving the strength and confirming the window installation by filling the injection material into the closed space at the crack site when using the TPS method compared with the syringe method. In addition, it is expected that construction time will be improved by shortening the construction period of about 5 days for the TPS construction method construction section 532 m, and usability will be expanded by the crack repair method of concrete structure.

본 연구는 기계주입 방식으로 간단히 재충전 할 수 있는 TPS 공법을 사용하여 실제 건설현장에 적용한 후 콘크리트 균열에 미치는 영향을 알아보고자 하였는데, 그 결과를 요약하면 다음과 같다. 먼저, 초음파 속도의 경우 TPS 공법을 사용하였을 시 주사기 공법에 비해 평균 약 36 mm/sec로 초음파가 빠른 속도로 통과하는 것을 알 수 있었고, 주입깊이의 경우 주사기 공법에서는 부분 충전되는 것을 확인하였으나 TPS 공법의 경우 강한 주입 압력으로 모든 배합에서 보수재가 100% 충전되는 우수한 경향을 나타내었다. 또한, 압축강도의 경우는 TPS 공법 사용 시 평균 16.8 % 증가하는 것으로 나타나 구조적으로 우수한 것으로 나타났다. 이상을 종합하면 주사기 공법에 비해 TPS 공법을 사용하였을 시 균열부위에 주입재가 밀실하게 충전되어 강도 증진으로 인한 품질 향상 및 확인창 설치로 인한 균열보수제의 거동이 확인 가능하다. 또한, TPS 공법 시공구간 532 m에 대하여 약 5일의 공사 기간이 단축됨에 따라 시공성이 우수하여 콘크리트 구조물에 균열 보수공법으로 사용성이 확대될 것으로 기대된다.
