관로 수밀 및 기밀 시험시스템{Pipeline water tightness and tightness test system}Pipeline water tightness and tightness test system

본 발명은 관로 수밀 및 기밀 시험시스템에 관련되며, 보다 상세하게는 관로 내에 팽창튜브를 투입하여 팽창시킨 후, 검사라인을 통하여 균열검사용 충진재를 압력실로 주입하면서 충진재 누적주입량, 주입속도, 충진재 온도, 주입시간을 포함하는 주입정보를 검출하고, 주입정보를 이용하여 균열여부, 균열면적을 포함하는 균열정보를 효과적으로 검출할 수 있는 관로 수밀 및 기밀 시험시스템에 관한 것이다.The present invention relates to a pipeline watertightness and airtightness test system, and more specifically, after injecting an expansion tube into a pipeline and inflating it, while injecting a crack inspection filler into a pressure chamber through an inspection line, the accumulated filler injection amount, injection speed, and filler temperature It relates to a pipeline watertightness and airtightness test system capable of detecting injection information including injection time and effectively detecting crack information including whether cracks exist and crack area using injection information.

통상 노후 하수관의 파손 및 균열로 인해 하수관로 내부로 지하수 등 불명수가 유입될 경우 하수처리량 증가로 인해 처리비용이 증가하고 결국 국가 예산을 낭비하게 되어 경제적으로 큰 손실이 발생하게 된다. 또한 최근 사회적 이슈로 도심지 지반함몰로 인해 인적물적 피해 사례가 많이 발생하고 있다.In general, when unknown water such as groundwater flows into the sewer pipe due to damage or cracks in the old sewer pipe, treatment costs increase due to the increase in sewage treatment volume, and eventually the national budget is wasted, resulting in large economic losses. In addition, as a recent social issue, there are many cases of human and material damage due to ground subsidence in downtown areas.

이러한 지반함몰의 원인이 다양하게 분석되고 있지만, 싱크홀 진단과 대책 정책 토론회 자료에 따르면 노후 하수관로 파손 및 균열로 인한 지반함몰이 전체 원인 중 84%로 주요 원인임을 확인할 수 있다. 그리고 30년 이상 경과한 노후 하수관이 전체 48% 수준으로 노후 하수관 불량으로 인한 지반함몰의 문제는 더욱 심각할 것으로 예상된다. 연도별 지반함몰 발생건수 및 예측 현황에서 2013년 기준 845건의 지반함몰이 발생했으며, 연평균 20% 이상 증가할 것이라는 예측을 제시하였다. 노후 하수관으로 인한 지반함몰 문제를 방관할 경우 대형재난으로 이어질 수 있으므로 이를 예방할 수 있는 대책 강구가 절실한 실정이다.Although various causes of ground subsidence have been analyzed, according to sinkhole diagnosis and countermeasure policy discussions, ground subsidence due to damage and cracks in old sewage pipes is the main cause, accounting for 84% of the total. In addition, the problem of ground subsidence due to poor old sewage pipes is expected to be more serious, as old sewage pipes that are more than 30 years old account for 48% of the total. In terms of the number of ground subsidence occurrences and forecast status by year, 845 ground subsidence cases occurred as of 2013, and it was predicted that the ground subsidence would increase by more than 20% per year. It is urgent to devise countermeasures to prevent this because neglecting the ground subsidence problem caused by old sewage pipes can lead to large-scale disasters.

따라서 노후 하수관로의 파손 및 균열 부위를 정확하게 확인하고 누수 부위를 정밀하게 보수할 수 있는 하수관로 보수기술 개발의 중요성이 대두되고 있다.Therefore, the importance of developing sewage pipe repair technology that can accurately check the damaged and cracked parts of the old sewer pipe and precisely repair the leaked part is emerging.

이에 종래에 개시된 등록특허 10-1932926호에서, 관로 균열부에 접하도록 외주면에 성형홈이 형성되는 팽창튜브와, 팽창튜브 양단을 마감하면서 주행휠이 구비되는 한 쌍의 측판과, 측판에 설치되어 팽창튜브 내부로 압축공기를 주입하는 공압라인과, 성형홈으로 보수제를 공급하는 보수제공급부를 포함하는 팩커본체; 상기 측판에 연결되어 팩커본체의 이동을 제어하는 로프; 상기 측판에 설치되어 팽창튜브 압력이 설정압력을 초과시 자동개방되거나, 안전핀을 당기면 수동 개방되어 팽창튜브 내부 공기를 배기하는 안전밸브; 상기 로프는 단부에 유동고리가 구비되고, 유동고리는 측판에 설치되는 고정고리에 연결되며, 유동고리에는 보조로프가 연장되어 안전밸브의 안전핀에 연결되어, 단일의 로프 조작으로 팩커본체 위치이동 및 팽창튜브 내부 공기를 배기하도록 구비되는 기술이 선 제시된 바 있다.Accordingly, in the conventionally disclosed Patent Registration No. 10-1932926, an expansion tube having molded grooves formed on the outer circumferential surface so as to come into contact with pipe cracks, a pair of side plates provided with running wheels while closing both ends of the expansion tube, and installed on the side plates A packer body including a pneumatic line for injecting compressed air into the expansion tube and a repair agent supply unit for supplying the repair agent to the forming groove; a rope connected to the side plate to control the movement of the packer body; a safety valve installed on the side plate and automatically opened when the pressure of the expansion tube exceeds the set pressure, or manually opened when a safety pin is pulled to exhaust air inside the expansion tube; The rope is provided with a floating ring at the end, the floating ring is connected to a fixed ring installed on the side plate, and an auxiliary rope is extended to the floating ring and connected to the safety pin of the safety valve, and the packer body is moved by a single rope operation, and A technique provided to exhaust the air inside the expansion tube has been previously suggested.

그러나, 상기 종래기술은 관로 균열부 보수작업을 효과적으로 수행하기 위한 것이나, 균열부 보수작업을 수행하기 전단계에서, 내시경 카메라로 촬영된 영상정보에 의존하여 균열부 상태를 파악한 후 보수제를 투입함에 따라 균열부 공간이 협소한 경우 과도한 보수제 주입 압력으로 추가 균열이 발생되고, 또 균열부 및 균열부 유출수로 인해 싱크홀이 발생된 경우 보수제 부족으로 균열부 주변 지반 강도를 보강할 수 없는 문제점이 따랐다. However, the prior art is intended to effectively perform repair work on cracks in pipelines, but at the stage before carrying out repair work on cracks, the condition of the cracks is identified by relying on image information captured by an endoscope camera, and then the repair agent is injected to repair the cracks. When the subspace is narrow, additional cracks occur due to excessive water retention agent injection pressure, and when sinkholes occur due to cracks and runoff from cracks, the ground strength around the cracks cannot be reinforced due to lack of water retention agent.
