초록

마시는 물은 인간의 기본적인 생활권 보장을 위한 필수적 요소로 깨끗한 물에 대한 품질은 항상 확보되어야 한다. 하지만 국내 수도시설을 집중 설치하였던 2000년 초반을 기점으로 현재 노후 상수도 시설이 증가하고 있으며, 색도 및 탁도와 같은 물의 변색, 이물질 누출 등의 사고가 빈번히 발생하고 있다. 실제로 모든 관의 교체는 불가능하기 때문에 2021년 제정된 상수관망시설 유지관리업무 세부기준에서는 상수관 세척을 의무화 하였으며, 다양한 세척 공법들을 통해 유지관리가 이루어지고 있는 실정이다. 상수관 세척 공법 중 스왑피그 공법은 관 내 이물질을 물리적으로 제거하는 방법으로 세척 효율이 가장 높은 것으로 평가 받고 있다. 하지만, 세척과정에서 스왑피그의 파손 및 변형에 따라 세척 효율은 변화하며, 분실의 가능성이 존재한다. 따라서 본 연구에서는 피그 자체의 재료를 변경하여, 압축력 및 관 내벽과의 밀착력을 향상시키고자 하며, 세척 효율 극대화를 위해 회전 블레이드를 삽입된 회전식 스왑피그를 개발하였다. 또한, 분실 가능성을 제거하고, 피그의 위치 파악을 위해 고강도 와이어 및 권취 장치를 추가적으로 개발하여, 투입구부터 토출구까지를 연결하였다. 각 세부 기술의 성능 검증 이후에는 30m 구간의 테스트베드에서 본 기술을 적용하였으며, 현장 적용성 평가와 더불어 공정 시간을 측정하여 기술의 성능을 검증하였다.

Drinking water is an essential element to ensure the basic human right to live, and the quality of clean water must always be ensured. However, domestic water facilities, which were installed intensively in the early 2000s, are deteriorating. The accidents such as discoloration of water such as chromaticity and turbidity as well as leakage of substances frequently occur. However, since it is virtually impossible to replace all water pipes, the detailed standards for maintenance of water pipe network facilities established in 2021 require water pipe cleaning. The swab pig method, one of the water pipe cleaning methods, is a method of physically removing substances in pipes and is evaluated as having the highest cleaning efficiency. However, Swab is highly likely to be damaged or deformed during the cleaning process, and may even be lost. Therefore, in this study, the material of the pig was changed to a material with high compressibility, and it was made as close as possible to the inner wall of the water pipe. And, to maximize cleaning efficiency, a rotation swab pig with a rotation blade was developed. In addition, high-strength wire and winding equipment were additionally developed to eliminate the possibility of loss and to determine the location of the pig. The inlet and outlet are connected with wires, and after verifying the performance of each detailed technology, the technology was applied on a test bed with a 30m section. As a result of the application, the performance of the technology was verified by measuring the process time and evaluating applicability.
