Description
본 발명은 지하에 매설되어 연결장치를 통해 서로 연결되는 이중벽관에 관한 것으로, 특히 서로 연결되는 이중벽관의 연결부를 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있도록 된 홈조인트식 이중벽관에 관한 것이다.The present invention relates to a double wall pipe buried underground and connected to each other through a connection device, in particular a home joint type that can thoroughly block the leakage or leakage at the pipe connection by connecting the connection of the double wall pipe connected to each other more closely It is about double wall pipe.
일반적으로, 우수, 오폐수 등과 같은 각종 하수나 농업용수 등은 지하에 매설된 관에 의해 수송되는 바, 이러한 관은 하수종류에 따라 여러가지 물리화학적인 특성이 요구된다. 예컨대 오폐수용 관은 오폐수에 함유된 화학성분이나 해조류, 박테리아 등의 세균류가 번식되지 않도록 하면서 토양 중에 존재하는 부식성 물질에 의해 부식이 전혀 되지 않는 내식성이 요구된다. 뿐만아니라 지하 깊은 곳에 매설되어 지상으로 부터 큰 하중을 받으므로 큰 하중에 충분히 견디는 내하중성과 배관에 제약을 받지 않고, 지반침하에 따른 변형력을 수용할 수 있는 유연성을 함께 필요로 한다.In general, various sewage and agricultural water such as rainwater, wastewater, etc. are transported by underground pipes, which require various physicochemical properties according to the type of sewage. For example, waste water pipes require corrosion resistance that is not corroded by corrosive substances present in the soil while preventing the growth of chemical components, seaweeds, bacteria, and the like contained in the waste water. In addition, since it is buried deep underground and receives a large load from the ground, it requires both a load-bearing capacity that can withstand large loads and flexibility to accommodate deformation forces due to ground subsidence.
따라서, 관은 통상 내식성 및 유연성을 구비한 고밀도 폴리에틸렌(HDPE) 관으로 성형한다. 그리고 지하매설시 지층에서 관에 가해지는 수직하중이나, 관을 둘러싸고 있는 지층의 반복적인 해빙에 의한 변형력에 대한 강성을 유지하기 위하여, 합성수지재로 이중벽 구조로 압출성형된 소형 중공관을 나선형으로 와인딩하면서 인접하는 외벽면 사이를 용융수지로써 서로 접합하여 제작한 관이 사용되고 있다.Thus, the tubes are usually molded from high density polyethylene (HDPE) tubes with corrosion resistance and flexibility. In order to maintain the rigidity against deformation due to vertical load applied to the pipe in the ground floor or repetitive thawing of the ground surrounding the pipe, the small hollow pipe extruded by double wall structure with synthetic resin is spirally wound. In the meantime, pipes produced by joining adjacent outer wall surfaces with molten resin to each other are used.
한편, 상기한 바와 같은 이중벽 구조를 가진 이중벽관은 도 1에 도시된 바와 같이, 사각 소형 중공관(101)이 나선형으로 권취되면서 서로 인접하는 측면들 사이에 충전되는 용융수지 접합재(102)에 의해 서로 접합되어 이중벽 구조를 가지는 이중벽관(103)을 이루는 것이다.Meanwhile, as shown in FIG. 1, the double wall tube having the double wall structure as described above is formed by the molten resin bonding material 102 filled between the adjacent sides while the rectangular small hollow tube 101 is spirally wound. It is joined to each other to form a double wall tube 103 having a double wall structure.
그리고, 상기 이중벽관(103)을 연결하는 경우 종래에는 서로 연결되는 각 이중벽관(103)의 선단부가 일치된 상태에서 그 연결부 외측에 고무링이 삽입설치되고, 상기 고무링의 외측에 일정 넓이를 갖는 커플링 밴드가 보울트와 너트에 의해 체결됨으로써 이중벽관(103)을 연결하도록 된 것이다.In the case of connecting the double wall pipe 103, a rubber ring is inserted into an outer side of the connection part in a state where the front ends of the double wall pipe 103 are connected to each other, and a predetermined width is provided outside the rubber ring. The coupling band having is fastened by the bolt and the nut to connect the double wall pipe (103).
그런데, 상기와 같이 이중벽관(103)과 이중벽관(103)을 단지 고무링과 커플링 밴드로 연결할 경우 그 수밀성이 낮고 기밀유지가 어렵기 때문에 이중벽관(103)의 이음부에서 누수현상이 일어나는 결점이 있고, 또한 상기 이중벽관(103)의 경우 사각 소형 중공관(101)을 나선형으로 권취하여 제작하는 파형관이기 때문에 서로 결합된 이중벽관(103)이 유동되는 경우 그 결합부 사이에 틈이 발생되어 상기 고무링이 이탈될 수 있고, 이에 따라 상기 고무링과 이중벽관(103) 연결부의 틈새를 통해 누수 및 누출현상이 일어나는 문제가 있었다.However, when the double wall pipe 103 and the double wall pipe 103 is connected only by the rubber ring and the coupling band as described above, water leakage occurs at the joint of the double wall pipe 103 because its watertightness is low and airtight is difficult to maintain. Since the double wall pipe 103 is a corrugated pipe manufactured by winding a rectangular small hollow tube 101 spirally in the case of the double wall pipe 103, a gap is generated between the coupling portions when the double wall pipe 103 is connected to each other. As a result, the rubber ring may be detached from each other, and thus, leakage and leakage may occur through the gap between the rubber ring and the double wall pipe 103.
이에 본 발명은 상기의 사정을 감안하여 안출된 것으로, 서로 연결되는 이중벽관의 선단부에 융착되는 조인트장치를 이용하여 이중벽관을 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있도록 된 홈조인트식 이중벽관을 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made in view of the above circumstances, by using a joint device fused to the distal end of the double wall pipe to be connected to each other more closely connected to the double wall pipe to be able to thoroughly prevent leakage or leakage at the pipe connection portion The purpose is to provide a groove joint double wall pipe.
상기한 바의 목적을 달성하기 위한 본 발명은, 사각 소형 중공관이 나선형으로 권취되면서 서로 인접하는 측면들 사이에 충전되는 용융수지 접합재에 의해 서로 접합되어 이중벽관 몸체를 이룸으로써 이중벽 구조를 가지는 이중벽관에 있어서, 서로 연결되는 각 이중벽관 몸체의 선단부가 원통형의 홈조인트 몸체에 삽입되어 열융착에 의해 고정되고, 상기 홈조인트 몸체의 외측에 고정돌기가 형성됨과 아울러 고정돌기와 인접되게 고정홈이 형성되고, 상기 홈조인트 몸체에 고정되는 고무링의 내측 선단에 각각 끼움돌기가 형성되어 홈조인트 몸체의 고정홈에 삽입되며, 상기 홈조인트 몸체와 연결되어 각 이중벽관 몸체를 서로 연결하는 조임용 캡의 내측 단부에 각각 걸림턱이 형성되어 이 걸림턱이 홈조인트 몸체의 고정돌기 외측에 걸려져 고정되는 구조이다.The present invention for achieving the above object is a double wall having a double-wall structure by forming a double-wall tube body is joined to each other by a molten resin bonding material filled between the adjacent sides of the rectangular small hollow tube spirally. In the pipe, the front end of each of the double wall pipe body connected to each other is inserted into the cylindrical groove joint body is fixed by heat fusion, the fixing projection is formed on the outside of the groove joint body and the fixing groove is formed adjacent to the fixing projection And a fitting protrusion is formed at each inner end of the rubber ring fixed to the groove joint body to be inserted into the fixing groove of the groove joint body, and connected to the groove joint body to connect each double wall pipe body to each other. Each locking jaw is formed at the inner end, and the locking jaw is fixed to the outside of the fixing protrusion of the groove joint body. A structure.
그리고, 상기 홈조인트 몸체의 고정돌기 외측에 일정간격을 두고 보강살이 형성되어, 상기 고정돌기와 보강살이 이루는 그루브에 상기 조임용 캡의 걸림턱이 삽입고정되는 것이다.Then, the reinforcement bar is formed at a predetermined interval on the outer side of the fixing protrusion of the groove joint body, and the locking jaw of the cap for tightening is inserted into the groove formed by the fixing protrusion and the reinforcing bar.
또한, 상기 조임용 캡이 복수개 상태로 분할되어 상기 홈조인트 몸체의 외측에 체결되는 것이다.In addition, the cap for tightening is divided into a plurality of states to be fastened to the outside of the groove joint body.
따라서, 상기 이중벽관의 선단에 설치된 홈조인트 몸체와 고무링 및 조임용 캡을 통해 이중벽관을 보다 용이하게 연결할 수 있고, 이중벽관을 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있으며, 이중벽관의 연결이 견고하게 이루어짐으로써 관의 유동에 의한 연결부의 벌어짐이나 파손을 최소화할 수 있는 것이다.Therefore, the double wall pipe can be more easily connected through the groove joint body and the rubber ring and the cap for installing the tip of the double wall pipe, and the double wall pipe is more closely connected to completely prevent leakage or leakage at the pipe connection part. In addition, since the connection of the double wall pipe is made firmly, it is possible to minimize the gap or breakage of the connecting portion by the flow of the pipe.
