Abstract
Description
본 발명은 지하에 매설되어 연결장치를 통해 서로 연결되는 적층관에 관한 것으로, 특히 서로 연결되는 적층관의 연결부를 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있도록 된 홈조인트식 적층관에 관한 것이다.The present invention relates to a laminated pipe buried underground and connected to each other through a connecting device, and in particular, by connecting the connection of the laminated pipes connected to each other more closely, a home joint type that can completely prevent leakage or leakage from the pipe connection It relates to a laminated tube.
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, 배수관은 통상 내식성 및 유연성을 구비한 고밀도 폴리에틸렌(HDPE) 관으로 성형한다. 그리고 지하매설시 지층에서 배수관에 가해지는 수직하중이나, 배수관을 둘러싸고 있는 지층의 반복적인 해빙에 의한 변형력에 대한 강성을 유지하기 위하여, 합성수지재로 압출성형된 중공관을 나선형으로 와인딩하면서 인접하는 외벽면 사이를 용융수지로써 서로 접합하여 제작한 이중벽 배수관이 사용되고 있다.Accordingly, drain pipes are usually molded from high density polyethylene (HDPE) pipes with corrosion resistance and flexibility. In order to maintain the stiffness against the vertical load applied to the drain pipe from the ground floor or the repetitive thawing of the ground that surrounds the drain pipe, the adjacent outer wall is spirally wound while winding the hollow pipe extruded with synthetic resin material. Double wall drain pipes fabricated by joining surfaces together with molten resin are used.
상기 이중벽 배수관은 나선형으로 와인딩되어 접합된 중공관의 격벽이 상하수직하중에 대한 강성을 보강해주게 되어 있지만, 중공부를 가지고 있으므로 비중이 상대적으로 적어서 수중에 설치되는 경우 부력을 받아서 부상하려고 하므로 이러한 구조의 이중벽 배수관은 지하에 매설되는 경우에 적합하지만, 수중 바닥에 설치하는 경우에는 부적합하다.The double wall drain pipe is spirally wound and the bulkhead of the hollow pipe joined to reinforce the rigidity of vertical load, but since it has a hollow portion, the specific gravity is relatively small, when installed in the water to try to rise due to buoyancy of this structure Double wall drains are suitable when buried underground, but not when installed on the water floor.
그러므로, 상기 이중벽 배수관의 단점을 보완하기 위하여 그 중공부에 합성수지재가 충전되어 관을 이루는 적층관이 개발되었는 바, 상기 적층관(101)은 도 1에 도시된 바와 같이 고밀도 폴리에틸렌으로 압출에 의해 성형되는 외측벽(102a) 내부에 다른 합성수지재가 압출에 의해 충전되어 내측벽(102b)을 이루는 적층바아(102)가 나선형으로 권취되면서 서로 인접하는 측면들 사이에 충전되는 용융수지 접합재(103)에 의해 서로 접합되어 관으로 성형된다.Therefore, in order to compensate for the shortcomings of the double wall drain pipe, a laminated pipe is formed in which the hollow part is filled with a synthetic resin material to form a pipe. The laminated pipe 101 is formed by extrusion of high density polyethylene as shown in FIG. 1. The other synthetic resin material is filled in the outer wall 102a by extrusion, and the laminated bar 102 forming the inner wall 102b is spirally wound and is filled with the molten resin bonding material 103 filled between adjacent sides. Joined and molded into a tube.
상기 적층관(101)은 측벽이 외측벽(102a) 내부에 내측벽(102b)이 충진된 적층구조로 됨으로써 외력에 충분한 강성을 유지하게 되는 것은 물론 중공관 구조의 관에 비하여 비중이 상대적으로 커서 물속에서 부상하지 않게 되는 효과가 있다.The laminated pipe 101 has a laminated structure in which the side wall is filled with the inner wall 102b inside the outer wall 102a, thereby maintaining sufficient rigidity for external force, and having a relatively high specific gravity compared to the hollow tube structure. There is no effect of being injured.
그리고, 상기 적층관(101)을 연결하는 경우 종래에는 서로 연결되는 각 적층관(101)의 선단부가 일치된 상태에서 그 연결부 외측에 고무링이 삽입설치되고, 상기 고무링의 외측에 일정 넓이를 갖는 커플링 밴드가 보울트와 너트에 의해 체결됨으로써 적층관(101)을 연결하도록 된 것이다.In the case of connecting the laminated pipe 101, a rubber ring is inserted into an outer side of the connection part in a state where the front ends of the laminated pipes 101 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 so as to connect the laminated pipe 101.
그런데, 상기와 같이 적층관(101)과 적층관(101)을 단지 고무링과 커플링 밴드로 연결할 경우 그 수밀성이 낮고 기밀유지가 어렵기 때문에 적층관(101)의 이음부에서 누수현상이 일어나는 결점이 있고, 서로 결합된 적층관(101)이 유동되는 경우 그 결합부 사이에 틈이 발생되어 상기 고무링이 이탈될 수 있으며, 이에 따라 상기 고무링과 적층관(101) 연결부의 틈새를 통해 누수 및 누출현상이 일어나는 문제가 있었다.However, when the laminated pipe 101 and the laminated pipe 101 are connected only by the rubber ring and the coupling band as described above, water leakage occurs at the joint of the laminated pipe 101 because the watertightness is low and airtightness is difficult. If there is a flaw and the laminated pipes 101 coupled to each other are flowed, a gap may be generated between the coupling parts so that the rubber ring may be separated. Accordingly, the gap between the rubber ring and the laminated pipe 101 may be separated. There was a problem of leakage and leakage.
이에 본 발명은 상기의 사정을 감안하여 안출된 것으로, 서로 연결되는 적층관의 선단부에 융착되는 조인트장치를 이용하여 적층관을 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있도록 된 홈조인트식 적층관을 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 laminated pipe connected to each other more closely connected to the laminated pipe to be able to thoroughly prevent leakage or leakage at the pipe connection portion The purpose is to provide a groove joint laminated tube.
상기한 바의 목적을 달성하기 위한 본 발명은, 고밀도 폴리에틸렌으로 압출에 의해 성형되는 외측벽 내부에 다른 합성수지재가 압출에 의해 충전되어 내측벽을 이루는 적층바아가 나선형으로 권취되면서 서로 인접하는 측면들 사이에 충전되는 용융수지 접합재에 의해 서로 접합되어 적층관 몸체를 이룸으로써 적층벽 구조를 가지는 적층관에 있어서, 서로 연결되는 각 적층관 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 적층관 몸체를 서로연결하는 조임용 캡의 내측 단부에 각각 걸림턱이 형성되어 이 걸림턱이 홈조인트 몸체의 고정돌기 외측에 걸려져 고정되는 구조이다.The present invention for achieving the object of the above is, between the sides adjacent to each other while the laminated bar constituting the inner wall of the inner wall of the outer wall is formed by the extrusion of the high-density polyethylene is filled by the extrusion to form the inner wall spirally wound In a laminated tube having a laminated wall structure by being bonded to each other by a filling molten resin bonding material to form a laminated tube body, the front end portions of each laminated tube body connected to each other are inserted into a cylindrical groove joint body and are fixed by heat fusion. Fixing protrusions are formed on the outer side of the groove joint body and fixing grooves are formed adjacent to the fixing protrusions, and fitting protrusions are formed at inner ends of the rubber rings fixed to the groove joint bodies, respectively, to the fixing grooves of the groove joint body. Tightening cap which is inserted and connected to the groove joint body to connect each laminated pipe body to each other Each of the locking jaws is formed at the inner end of the locking jaw is structured to be fixed to the outside of the fixing projection of the groove joint body.
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 적층관의 선단에 설치된 홈조인트 몸체와 고무링 및 조임용 캡을 통해 적층관을 보다 용이하게 연결할 수 있고, 적층관을 보다 긴밀하게 연결함으로써 관 연결부에서의 누수나 누출을 철저히 차단할 수 있으며, 적층관의 연결이 견고하게 이루어짐으로써 관의 유동에 의한 연결부의 벌어짐이나 파손을 최소화할 수 있는 것이다.Therefore, the laminated pipe can be more easily connected through the groove joint body and the rubber ring and the cap for the cap installed at the front end of the laminated pipe, and by closely connecting the laminated pipe, it is possible to thoroughly block leakage or leakage at the pipe connection part. In addition, since the connection of the laminated pipe is made firmly, it is possible to minimize the gap or breakage of the connection part by the flow of the pipe.
