비굴착식 하수관 보수용 튜브란 굴착공사 없이도 하수관을 보수 할 수 있도록 제조된 튜브(Tube) 이다. 비굴착식 하수관 보수용 튜브를 사용하는 경우 굴착공사를 생략 할 수 있기 때문에 하수관 보수공사 기간이 단축되고, 교통장애 및 굴착시의 안전사고 등을 예방 할 수 있는 장점이 있다. 따라서 향후 비굴착식 하수관 보수용 튜브는 보다 많이 사용될 것으로 전망 된다.Non-excavated sewer pipe repair tube is a tube manufactured to repair the sewer pipe without excavation work. In the case of using non-excavated sewer pipe repair tube, the excavation work can be omitted, so the sewer pipe repair work can be shortened, and traffic obstacles and safety accidents during excavation can be prevented. Therefore, non-excavated sewer repair tube is expected to be used more in the future.
비굴착식 하수관 보수용 튜브를 사용하여 하수관을 보수하는 공정은 통상 하수관내 준설 및 세정을 하는 1단계 공정, CCTV 카메라 등을 이용하여 연결관의 돌출부위 절단 및 관내 정밀조사를 하는 2단계 공정, 하수관 보수용 튜브에 열경화성 수지를 함침시킨 후 이를 냉동차를 이용하여 현장으로 이동시키는 3단계 공정, 수압 이나 공기압을 이용하여 하수관 보수용 튜브를 반전시킨 후 이를 하수관 내로 삽입 시키는 4단계 공정, 하수관 보수용 튜브 내로 온수나 스팀 등을 주입하여 튜브 내에 함침된 열경화 수지를 열경화시키는 5단계 공정, 하수관 양측을 절단하고 입구를 정리하는 6단계 공정, 연결관을 개통하고 마무리 작업하는 7단계 공정 및 최종적으로 하수관을 최종 검사하는 8단계 공정으로 이루어 진다.The process of repairing sewer pipes using non-excavated sewer pipe repairing tubes is usually a one-step process of dredging and cleaning in sewage pipes, a two-step process of cutting the protruding portion of the connection pipes using a CCTV camera, and inspecting the inside of the pipes. 3 step process of impregnating thermosetting resin in sewage pipe repair tube and moving it to the site using a refrigerating vehicle, 4 step process of inverting sewage pipe repair tube using water pressure or air pressure and inserting it into sewage pipe, sewage pipe repair 5-step process of thermosetting the thermosetting resin impregnated into the tube by injecting hot water or steam into the tube, 6-step process of cutting both sides of the sewer pipe and cleaning the inlet, and 7-step process of opening and finishing the connecting pipe and finally It consists of an eight-step process for final inspection of sewer pipes.
종래 비굴착식 하수관 보수용 튜브는 도 2와 같이 원통상의 부직포(1) 상에 방수필름(2)이 코팅 또는 라미네이팅 된 구조를 갖는다. 이때 원통상의 부직포(1)는 평면상의 부직포를 원통상으로 성형한 다음, 양쪽 가장자리를 서로 접착제나 열 등록 접합 또는 접착하여 제조한다. 따라서 종래 비굴착식 하수관 보수용 튜브를 구성하는 원통상 튜브(1)에는 도 3과 같이 접합부(3)가 존재하게 된다. 상기 원통상 튜브(1)에 존재하는 접합부는 하수관 보수용 튜브가 하수관내에 준설되어 사용시 튜브의 기계적 물성을 저하시키는 요인이 되고 있다.Conventional non-drillable sewer repair tube has a structure in which the waterproof film 2 is coated or laminated on the cylindrical nonwoven fabric 1 as shown in FIG. At this time, the cylindrical nonwoven fabric 1 is manufactured by forming a planar nonwoven fabric into a cylindrical shape, and then bonding both edges to each other with adhesive or heat registration bonding or bonding. Therefore, the joint part 3 exists in the cylindrical tube 1 which comprises the conventional non-excavation sewer pipe repair tube like FIG. The joining portion present in the cylindrical tube 1 is a factor that reduces the mechanical properties of the tube when the sewer pipe repair tube is dredged in the sewer pipe.
