본 고안은 주로 시설 전후에 상, 하수관과 같은 유체관(流體官)의 누출부를 검출하거나 붕괴된 하수관의 보수시 유체를 우회시키기 위해 파이프의 양 개구부를 밀폐시킬 수 있도록 된 것으로 특히 수관의 내경이 맨호울의 내경보다 큰 경우에 사용되는 밀폐기에 관한 것이다.The present invention is mainly designed to seal both openings of the pipes in order to detect leaks in fluid pipes such as water and sewage pipes before and after the facility or to divert the fluid during repair of collapsed sewer pipes. It relates to an airtight sealer used when larger than the inner diameter of the manhole.

종래 관의 누출을 검사하기 위해서는 관의 직경보다 약간 작은 원판외주면에 탄성재의 테를 둘러 관의 개구를 틀어막는 정도의 부실한 작업으로 관의 밀폐가 행해졌기 때문에 작업상의 어려움은 물론 기대할 만한 확실한 밀폐 효과를 얻지 못하며, 보수관의 내경이 맨호울의 구멍보다는 큰 경우에는 관을 밀폐 시키지 못한 채 배수 펌프에만 의존하여 유수를 외부로 흘러 보내게 되므로 붕괴된 관을 교체하기 위해 많은 시간이 소비되며 교체 작업이 매우 어려움 점이 있었다.In order to inspect the leak of a conventional pipe, the sealing of the pipe was performed by a poor work such as closing the opening of the pipe by surrounding the rim of the elastic material on the outer circumferential surface of the disc, which is slightly smaller than the diameter of the pipe. If the inner diameter of the conservative pipe is larger than the hole of the manhole, it will be time-consuming and necessary to replace the collapsed pipe since it will flow out of the water by relying only on the drain pump without sealing the pipe. This was a very difficult point.

본 고안은 이러한 종래의 문제점을 해결하기 위해 반원형 프레임 2개를 결합시켜 원형의 드럼으로 구성하며, 이 드럼에 고무재로된 도너츠형의 튜우브를 끼워 지지시키기 위해 보호판을 드럼의 양측에 고정시키므로써 튜우브가 압축공기에 의해 팽창될 때 튜우브의 내주면은 드럼의 외주면에 밀착 지지되는 동시에 튜우브는 관의 내부면에 대하여 팽창증대하여 관의 개구 내주면을 밀착시키게 되는 것이며 또한 각 프레임 배기(排氣)관과 수관(水官)을 서로 대응하게 설비시키고 배기관에는 압력개를 부착한 밀폐기로서 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention combines two semi-circular frames to form a circular drum, and the protection plates are fixed to both sides of the drum to support the donut-shaped tubing made of rubber. When the tube is inflated by compressed air, the inner circumferential surface of the tube is closely supported by the outer circumferential surface of the drum, and the tube is expanded and expanded with respect to the inner surface of the tube so as to closely adhere to the inner circumferential surface of the tube.排氣) Pipe and water pipe (水 官) to be installed corresponding to each other and the exhaust pipe attached to the pressure dog as described in detail according to the accompanying drawings as follows.

본 고안의 밀폐기(1)는 원주방향으로는 암나사(4)를 양측면에 형성하고 접합면(5)의 수직으로는 체결공(5a)을 등간격으로 천공한 반원형 좌, 우측 프레임(3)(3')사이에 유체가 통하지 못하게 밀폐하기 위한 패킹(6)을 넣고 볼트(7)와 너트(7a)로서 접합면의 체결공(5a)을 통해 결합하여 원형의 드럼(2)으로 구성하여 이때 드럼의 중량을 줄이면서 높은 수압에 견딜 수 있게 리브(3a)를 좌, 우측 프레임(3)(3')의 양측면에 돌출 형성하고, 좌측프레임(3)의 하단에는 수관(8)을, 우측 프레임(3')의 상단에는 배기관(9)을 각각 관통되게 용접하였으며, 상기 드럼(2)의 외주면으로 도너츠형의 튜우브(10)의 내주면이 접하게 삽지시켜 보호판(11)에 천공된 제결공(11a)과 좌, 우측 프레임(3)(3')의 암나사(4)와 일치시켜 볼트(7')로 결합시키므로 보호판 (11)이 격벽의 역할을 하여 튜우브(10)의 페트코크(peot cock) (10a)로 주입된 공기 압력에 의해 튜우브(10)는 원주 방향으로만 팽대하게 한 것으로서, 도면 설명중 미설명 부호 P는 수압측정을 위한 관, 12는 관(P)내의 수압 측정을 위한 압력계, 13은 밸브, A는 맨홀의 내경, B는 하수관의 내경이다.The sealer 1 of the present invention has a semicircular left and right frame 3 formed with female threads 4 on both sides in the circumferential direction, and perforated fastening holes 5a at equal intervals in the vertical direction of the joining surface 5. Put a packing (6) for sealing the fluid (3 ') through the (3') through the fastening hole (5a) of the joint surface as a bolt (7) and nut (7a) to form a circular drum (2) At this time, the rib 3a is protruded on both sides of the left and right frames 3 and 3 'so as to withstand high water pressure while reducing the weight of the drum, and the water pipe 8 is formed at the lower end of the left frame 3, The exhaust pipe 9 is welded through the upper end of the right frame 3 ', and the inner circumferential surface of the donut-shaped tube 10 is inserted into the outer circumferential surface of the drum 2 so as to be in contact with the protective plate 11. Since the holes 11a and the female screws 4 of the left and right frames 3 and 3 'are matched with the bolts 7', the protective plate 11 acts as a partition wall, The tub 10 is expanded only in the circumferential direction by the air pressure injected into the pet cock 10a of (10), and reference numeral P in the description of the drawing denotes a pipe for measuring water pressure, 12 Is a pressure gauge for measuring water pressure in the pipe P, 13 is a valve, A is an inner diameter of a manhole, and B is an inner diameter of a sewer pipe.

이와 같이 구성된 밀폐기(1)는 제4도에서 도시한 바와 같이 밀폐하려는 관(P)의 개구부 양측에 끼워 설치하고 외부에서 에어펌프(도시않음)로 튜우브(10)의 페트코크(10a)를 통해 공기를 주입시키면 튜우브(10)는 팽대해지면서 내주면은 내경의 변형없이 드럼(2)의 외주면에 밀착되는 동시에 보호판(11)에 의해 측면이 저지되어 튜우브(10)의 외주면은 관(P)의 개구부 내주면을 향해 팽대해지므로 관을 밀폐시키는 것이다. 상기와 같이 판의 양측 개구부를 밀폐시킨 후 배기관(9) 및 수관(8)의 밸브(13')(13)를 각각 개방하고 시험수를 수관(8)으로 주입시켜 관(P)내에 충진되면 배기관(9)의 밸브(13')를 막고나서 배기관(9)의 일측에 결합된 압력계(12)의 지시에 따라 일정한 수압이 유지될 때 수관(8)의 밸브(13)를 밀폐시켜 관내의 실정 수압이 장시간 유지되는 지의 여부에 따라 관의 누출을 알 수 있게 되며, 밀폐기(1)를 관(P)으로부터 제거할 때에는 페트코크(10a)의 밸브를 열어 압축상태를 공기를 빼내면 튜우브는 수축하여 관의 내측면으로부터 떨어지게 된다.The sealer 1 configured as described above is fitted to both sides of the opening of the pipe P to be sealed, as shown in FIG. 4, and the pet coke 10a of the tub 10 is provided with an air pump (not shown) from the outside. Injecting air through the tube 10 is expanded while the inner circumferential surface is in close contact with the outer circumferential surface of the drum (2) without deformation of the inner diameter and at the same time the side surface is blocked by the protective plate 11, the outer circumferential surface of the tub 10 It expands toward the inner circumferential surface of the opening of (P), thereby sealing the tube. After closing the openings on both sides of the plate as described above, the valves 13 'and 13 of the exhaust pipe 9 and the water pipe 8 are opened, and the test water is injected into the water pipe 8 to fill the pipe P. After the valve 13 'of the exhaust pipe 9 is blocked, the valve 13 of the water pipe 8 is sealed by the pressure gauge 12 coupled to one side of the exhaust pipe 9 to maintain the water pressure. If the actual water pressure is maintained for a long time, it is possible to know the leak of the pipe.When removing the sealer 1 from the pipe P, open the valve of the pet coke 10a to extract the compressed air, and The woven contracts and falls away from the inner side of the tube.

또한 본 고안은 제5도에서 도시한 바와 같이 붕괴된 하수관을 교체하기 위해 적용한 상태를 나타낸 것으로서, 맨호울의 내경(a)이 하수관의 내경(b)보다 작을 경우 제1도에서 도시한 바와 같이 분해된 부품을 하수구 맨호울 안에서 결합하여 밀폐기(1)를 구성한다. 이때의 결합순서는 다음과 같다. 수관(8)과 배기관(9)을 용접한 좌,우측 프레임(3)(3')사이에 패킹(6)을 넣고 접합면(5)에 두줄로 등간격 천공된 체결동(5a)을 일치시켜 볼트(7)와 너트(7a)로 밀착되게 결합하여 원형의 드럼(2)을 형성한 후 도너츠형의 튜우브(0)의 패트코크(10a)가 수관과 배기관이 있는 방향으로 향하게 하여 튜우브(10)의 내주면과 드럼(2)의 외주면에 접하게 삽입하며 좌, 우측프레임(3)(3')의 원주상에 등간격으로 형성된 암나사(4)와 보호판(11)에 천공된 체결공(11a)과 일치시켜 볼트(7')로 고정하므로 보호판(11)이 격벽의 역할을 튜우브(10)가 이탈되지 못한다.In addition, the present invention shows a state applied to replace the collapsed sewer pipe as shown in Figure 5, as shown in Figure 1 when the inner diameter (a) of the manhole is smaller than the inner diameter (b) of the sewer pipe The disassembled parts are combined in the sewer manhole to form the sealer (1). The joining order at this time is as follows. A packing 6 is inserted between the left and right frames 3 and 3 'on which the water pipe 8 and the exhaust pipe 9 are welded, and the fastening holes 5a equally spaced in two lines on the joint surface 5 coincide. The bolt 7 and the nut 7a to be in close contact with each other to form a circular drum 2, and then the pat coke 10a of the donut-shaped tube 0 is directed in the direction of the water pipe and the exhaust pipe. Fastening hole drilled in the inner threaded surface of the woofer 10 and the outer peripheral surface of the drum 2 in contact with the female screw 4 and the protective plate 11 formed at equal intervals on the circumference of the left and right frames 3, 3 ′. Since the tube 11 is fixed in accordance with 11a and fixed with the bolt 7 ', the tub 10 does not escape the role of the partition wall.

이와 같이 결합된 밀폐기(1)를 흐르는 하수를 펌프로 우회시키도록 하수관을 밀폐시키고 수관(8)에 펌프의 호오스를 연결하므로 붕괴된 하수관을 신속히 보수하게 되며 관을 교체한 후 결합의 역순으로 밀폐기(1)를 분해하여 제거하므로 원상태의 하수구를 유지할 수 있는 편의를 도모한 것이다.In this way, the sewage pipe is sealed to bypass the sewage flowing through the combined sealer 1 with the pump, and the hose of the pump is connected to the water pipe 8 so that the collapsed sewage pipe can be repaired quickly. Since the sealer 1 is disassembled and removed, the convenience of maintaining the original sewer is intended.

그러므로 본 고안은 맨호울의 입구가 협소하고 하수관의 내경이 광대할 경우 신속히 조립하여 밀폐와 동시에 유체를 우회시킬 수 있는 효과를 갖는 것이다.Therefore, the present invention has an effect of quickly assembling and bypassing fluid at the same time when the inlet of the manhole is narrow and the inner diameter of the sewer pipe is large.
