It is made of a straight pipe inserted to be maintained, and the reinforcement means, such as having a separation prevention means to prevent the separation by the pressure of the tap water to the connection portion of the water pipe, or to reinforce and support the clamp.

이와 같이 수도관의 연결부위의 이탈방지를 방지하기 위한 선행기술에는 공개특허 10-2005-0120613호(발명의 명칭 : 이탈방지용 일체형 편수 이음관), 등록특허 10-1021190호(발명의 명칭 : 타이튼 조인트식 상수도관 연결구조) 및 등록특허 10-1424965호(발명의 명칭 : 수밀링 밀림 방지형 상수도관)가 제공되고 있다.As described above, the prior art for preventing the separation of the connection portion of the water pipe is disclosed in Korean Patent Publication No. 10-2005-0120613 (Invention name: integral single-piece joint pipe for prevention of departure), Patent No. 10-1021190 (Invention name: Tyton Joint type water pipe connection structure) and Patent No. 10-1424965 (name of the invention: water milling anti-shrink water pipe) is provided.

이와 같은 선행기술의 이탈방지용 일체형 편수 이음관은 몸체 내부의 패킹삽입부와 로크링삽입부에 패킹과 로크링이 삽입된 로크링 케이스를 삽입한 다음, 로크링 및 패킹의 내주면을 통하여 연결관의 외주면을 삽입하는 구조로서, 패킹삽입부에 삽입되는 패킹으로써 수밀을 유지함에 따라 수밀력이 저하되고, 로크링로써 연결관을 고정시킴으로써 연결관의 고정이 용이하지 않을 뿐만 아니라, 연결관의 삽입을 제한하기 위해서는 몸체에 걸림턱을 형성해야 하는 구조적인 문제점을 갖게 되었다.The integrated single-piece fitting pipe for preventing the separation of the prior art is inserted into the packing insert portion and the lock ring insert portion inside the body, and then inserts the lock ring case with the packing and the lock ring inserted therein, and then, through the inner circumferential surface of the lock ring and the packing, As the outer circumferential surface is inserted, the watertight force decreases as the packing inserted into the packing insertion portion maintains the watertightness, and it is not easy to fix the connection pipe by fixing the connection pipe by the locking ring, In order to limit the structural problem has to form a locking step on the body.

또한, 선행기술의 타이튼 조인트식 상수도관 연결구조는 상수도관 본체의 일측 단부에 확장된 소켓부가 형성되고, 소켓부에 다른 상수도관 본체의 일측 단부인 관삽입부가 내삽되어 관 연결되며, 관삽입부의 선단에 고무링의 내면과 접촉하는 진입방향으로 경사면을 형성한 테이퍼링이 설치되고, 관 연결부의 외경이 감싸지도록 상하 반체로 이루어진 이탈방지 클램프가 볼트 결합되는 구조로서, 이는 관삽입부가 소켓부 내주면에 삽입되는 고무링에 의해 수밀이 유지되어 수밀력이 저하되고, 상수도관의 이음 부위에 이탈방지 및 관의 삽입을 제한하기 위한 클램프의 설치에 따른 소켓부의 구조를 변경해야 하는 문제점이 발생 되었다.In addition, the Titon joint type water pipe connection structure of the prior art is formed with an extended socket portion at one end of the water supply pipe body, the pipe insertion portion is inserted into the socket portion of the other end of the water pipe body, the pipe is connected, At the tip of the part, a tapered ring is formed with an inclined surface in the entry direction in contact with the inner surface of the rubber ring, and a separation prevention clamp composed of upper and lower halves is bolted to cover the outer diameter of the pipe connection part. Watertightness is maintained by the rubber ring inserted into the watertight force, the watertight force is lowered, and the problem of changing the structure of the socket part according to the installation of the clamp to prevent the separation and the insertion of the pipe in the joint portion of the water supply pipe has occurred.

또한, 선행기술의 수밀링 밀림 방지형 상수도관은 관체부보다 큰 사이즈로 확관된 형상을 갖는 곳에 편각허용부, 단차홈부, 벨 형상의 끝단부를 갖는 상하수도관을 제공하여, 지반 침하시 허용 처짐각, 즉 편각을 허용할 수 있고, 지반 침하로 인하여 수밀링에 국부적으로 과도한 응력이 발생되는 문제점이 해결되었다.In addition, the water-tight rolling prevention water pipe of the prior art provides a water supply and sewage pipe having a declination allowable part, a step groove, a bell-shaped end portion in a place having a shape expanded to a size larger than the pipe portion, the allowable deflection angle on the ground That is, the deflection can be allowed, and the problem that local stress is excessively generated due to ground subsidence has been solved.

그러나 이러한 선행기술은 단차홈부에 삽입되는 수밀링에 의해 다른 상수관의 관체부에 대한 수밀이 유지되고, 이탈이 방지되는 구조로서, 이는 수압에 의한 수밀이 저하되고, 관체부의 이탈이 쉽게 이루어지는 문제점을 갖게 되었다.However, this prior art is a structure in which the watertightness of other water pipes is maintained by the water-tight ring inserted into the stepped grooves, and the separation is prevented. This is a problem in that the watertightness is reduced by water pressure and the separation of the water pipes is easy. Got
