Description

상수도관 무단수 보수공사 방법{METHOD OF REPAIR WORK ON WATER SUPPLY PIPE WITHOUT SUSPENSION OF WATER SUPPLY}METHOD OF REPAIR WORK ON WATER SUPPLY PIPE WITHOUT SUSPENSION OF WATER SUPPLY}

본 발명은 상수도관의 노후 등으로 인한 보수 시에 사용하는 방법으로서, 구체적으로는 누수현장에서 단수조치 없이 상수도관을 보수하는 방법에 관한 것이다.The present invention relates to a method for repairing waterworks due to aging, etc., and specifically, to a method for repairing a water supply pipe without a single action at a leak site.

종래, 사용수명의 도래 등으로 인해 노후화된 상수도관은 누수발생 시 해당구간을 포함하는 상수도 공급지역 전체로 일시적 단수조치를 시행한 상태에서 관 교체 작업을 수행하였으나, 비교적 대규모의 교체공사로서 재정부담이 됨은 물론이거니와 단수로 인한 주민불편 및 민원제기가 문제됨에 따라 저비용의 무단수 보수공사 방법이 제안되고 있다.Conventionally, aging water pipes due to the advent of service life, etc., performed pipe replacement work in the state where temporary water supply measures were applied to the entire water supply area including the corresponding section in the event of a leak, but as a relatively large-scale replacement work, financial burden In addition to this, as a result of residents' complaints and complaints due to the singular, problems with low-cost unauthorized repairs have been proposed.

대표적인 상수도관 무단수 보수공사 방법은 특허등록 제10-0749550호(등록일자: 2007.08.08.)에 개시된 것으로서 도 1에 도시된 바와 같이 송수관(100)의 누수지점에서 관의 테두리로 2개의 플랜지부(200)를 체결하여 감싼 다음 외주면을 따라 형성된 다수의 탭(230)을 통해 돌아가며 컴파운드를 주입한 다음, 각 탭(230)에 무두볼트(headless bolt)를 체결하여 마무리하는 방법을 제안하고 있다. 플랜지부(200) 내에 채워진 컴파운드가 굳으면서 누수를 막는다.A representative water supply pipe repair method is disclosed in patent registration No. 10-0749550 (registration date: 2007.08.08.), As shown in Fig. 1, two plans from the leak point of the water pipe 100 to the border of the pipe It is proposed to wrap the branch 200 and then wrap it through a plurality of tabs 230 formed along the outer circumferential surface to inject a compound, and then finish by tightening a headless bolt on each tab 230. . The compound filled in the flange portion 200 is solidified to prevent leakage.

그러나, 이러한 방법은 플랜지부(200)와 송수관(100) 사이의 틈새를 통해 누수가 계속될 수 있어 이에 대한 대책이 미비하다는 문제가 있다. 또한, 무단수 조치인 관계로 물이 계속 새어나오고 있는 상태에서 좁은 플랜지부(200) 내측의 공간은 금방 물이 차올라 새어나오게 되므로 탭(230)을 통해 주입되는 컴파운드가 새어나오는 물에 씻겨나와 함께 외부로 유출될 우려도 있다.However, this method has a problem in that countermeasures are insufficient because water leakage may continue through the gap between the flange portion 200 and the water pipe 100. In addition, because the water is continuously leaking due to the stepless action, the space inside the narrow flange portion 200 is quickly leaked and water is leaking, so the compound injected through the tab 230 is washed in the leaked water. There is also a risk of leaking to the outside.

따라서, 본 발명의 목적은 종래기술에 비해 우수한 누수방지 효과를 달성하고 관을 통해 물이 계속 새어나오는 무단수 작업환경을 설계적으로 고려한 상수도관 무단수 보수공사 방법을 제공하는 데 있다.Accordingly, an object of the present invention is to provide a method for repairing a water supply pipe without water, which achieves an excellent water leakage prevention effect as compared to the prior art, and considers the waterless work environment in which water continuously leaks through the pipe.

As illustrated, clamps 10 and 20 are fastened to both left and right sides with the leak point 2 interposed therebetween. The clamps 10 and 20 are each divided into two bolt structures and assembled to each other by bolting, and the inner circumferential surface of the inner and outer projection lines 11, 12; 21, 22 contacting the outer circumferential surface of the water supply pipe 1 is S1. , S2) is formed between the outer peripheral surface of the water supply pipe (1). Further, a plurality of tabs (13, 23) are formed along the outer circumferential surfaces of the clamps (10, 20) to be connected to the interspace (S).

클램프(10, 20)가 체결되면, 원주방향으로 돌아가며 탭(13, 23)을 통해 컴파운드(compound)를 주입함으로써 상수도관(1)의 외주면에 원주방향으로 형성되는 사이공간(S1, S2)에 도 4에 도시된 바와 같이 컴파운드(C1, C2)가 충진되도록 한다. 이어서, 도 5에 도시된 바와 같이 각 탭(13, 23)에 무두볼트(headless bolt, 14, 24)를 나사결합하여 삽입, 고정함으로써 충진된 컴파운드(C1, C2)가 새어나오지 못하도록 막음 처리한다. 충진된 컴파운드(C1, C2)는 경화되어 클램프(10, 20)와 상수도관(1)의 외주면 사이를 밀폐시키게 된다.When the clamps 10 and 20 are fastened, they return to the circumferential spaces S1 and S2 formed in the circumferential direction on the outer circumferential surface of the water pipe 1 by injecting a compound through the tabs 13 and 23. 4, the compounds C1 and C2 are filled. Subsequently, as shown in FIG. 5, the headless bolts 14 and 24 are screwed into each tab 13 and 23 to be inserted and fixed to prevent the filled compounds C1 and C2 from leaking out. . The filled compounds C1 and C2 are cured to seal between the clamps 10 and 20 and the outer circumferential surface of the water supply pipe 1.

다음으로, 좌우 클램프(10, 20) 사이의 거리만큼의 축방향 길이를 갖는 상,하 2개의 반원통형 드럼(31, 32)를 도 6에 도시된 바와 같이 좌우 클램프(10, 20) 사이에 개재시킨 상태에서 서로 체결함으로써 누수지점(도 5의 2)을 포함하여 좌우 클램프(10, 20) 사이의 영역에서 상수도관(1)을 외부로부터 밀폐되도록 덮는다. 반원통형 드럼(31, 32) 간의 체결과정에서 누수지점(도 5의 2)으로부터 새어나오는 물은 하측 반원통형 드럼(32)의 하단부에 구비되는 배수구 플랜지(33)를 통해 아래로 유출될 수 있도록 한다.Next, the upper and lower two semi-cylindrical drums 31 and 32 having an axial length equal to the distance between the left and right clamps 10 and 20 are placed between the left and right clamps 10 and 20 as shown in FIG. 6. By fastening each other in the interposed state, the water supply pipe 1 is covered to be sealed from the outside in the region between the left and right clamps 10 and 20, including the leak point (2 in FIG. 5). In the process of fastening between the semi-cylindrical drums 31 and 32, water leaking from the leak point (2 in FIG. 5) can be discharged downward through the drain flange 33 provided at the lower end of the lower semi-cylindrical drum 32. do.

이어서, 도 6에 도시된 바와 같이 서로 체결된 반원통형 드럼(31, 32)의 정위치를 유지한 상태에서 드럼(30), 즉 서로 결합한 반원통형 드럼(31, 32)의 축방향 양측면(즉, 판면)과 클램프(10, 20)와의 접촉면을 따라 원주방향으로 용접하여 도 7에 도시된 바와 같이 용접선(W1, W2)을 형성함으로써 일체화한다. 이 과정에서도 누수지점(도 5의 2)으로부터 새어나오는 물은 하단의 배수구 플랜지(33)를 통해 아래로 유출된다.Subsequently, as shown in FIG. 6, while maintaining the correct position of the semi-cylindrical drums 31 and 32 fastened to each other, the drum 30, that is, the axial side surfaces of the semi-cylindrical drums 31 and 32 coupled to each other (ie , Plate surface) and welded in the circumferential direction along the contact surfaces of the clamps 10 and 20 to form welding lines W1 and W2 as shown in FIG. 7. Even in this process, water leaking from the leak point (2 in FIG. 5) flows down through the drain flange 33 at the bottom.

마지막으로, 배수구 플랜지(33)를 도 8에 도시된 바와 같이 막음판(34)으로 막음 처리함으로써 무단수 보수공사를 완료한다.Lastly, the endless water repair work is completed by blocking the drainage flange 33 with a blocking plate 34 as shown in FIG. 8.

한편, 이상에서 설명된 상수도관 무단수 보수공사 방법은 본 발명의 이해를 돕기 위한 일 실시예에 불과하므로 본 발명의 권리범위 내지 기술적 범위가 상기 설명된 바에 한정되는 것으로 이해되어서는 곤란하다. 본 발명의 권리범위 내지 기술적 범위는 후술하는 특허청구범위 및 그 균등범위에 의해 정하여진다.On the other hand, the water supply pipe endless water repairing method described above is only one embodiment for helping the understanding of the present invention, so it is difficult to understand that the scope of the present invention is limited to the technical scope of the present invention.
