Abstract

An assembly type conduit for an underground structure is provided to obtain water-stopping property of the conduit by firmly contacting the conduit to the concrete underground structure. An assembly fixing tube(10) is inserted into a conduit hole to be fixed by left and right coupling plates(30,30a) and has a support body(11) with a plurality of through holes, left and right coupling tubes(12) with outer screw units on outer peripheries, and anchor bolts(14) on inner peripheries of the left and right coupling tubes. Folded sealing rings(20,20a) are installed between the left and right coupling tubes and the assembly fixing tube to seal and have through holes on the extension lines of the through holes of the support body. The left and right coupling plates fix the assembly fixing tube to the conduit hole and have inner screw units coupled with the left and right coupling tubes, contact protrusion units(36) in contact with the folded sealing rings, bolt holes formed at the contact protrusions to be fixed by coupling nuts, and flange units(35) formed outside and inside the conduit hole. A bow-shaped sealing tube(40) is in contact with an underground conduit by a sealing balloon ring and has a bow-shaped concave unit with a bow-shaped cross section and anchor holes at both ends. The sealing balloon ring contacts the bow-shaped sealing tube to the underground conduit through air pressure to seal.

Description

지중구조물 조립식 관로구{SEALING GASKET BODY FOR ASSEMBLY TYPE OF SUBTERRANEAN STRUCTURE}Underground Structure Prefabricated Pipeline {SEALING GASKET BODY FOR ASSEMBLY TYPE OF SUBTERRANEAN STRUCTURE}

본 발명은 지중구조물 조립식 관로구에 관한 것으로서, 보다 상세하게는 관로구 및 관로구 덮개의 결합이 매우 손쉽게 이루어지고, 콘크리트 재질의 지중구조물에 관로구를 보다 견고하게 밀착시킬 수 있어 관로구 내의 지수성을 보다 확실하게 확보할 수 있는 지중구조물 조립식 관로구에 관한 것이다. The present invention relates to an underground structure prefabricated pipeline, more specifically, the combination of the pipeline and the pipe cover is made very easily, and can be more tightly adhered to the underground structure of the concrete material to ensure the exponent in the pipeline more reliably It is related with the underground structure prefabricated pipeline.

일반적으로 관로구는 전력배선의 가설에 사용되는 지중구조물의 측벽에 부착하여 필요에 따라 전력배선을 지중구조물 내부로 인입시키기 위한 관체의 출입구이다.In general, the conduit is an entrance and exit of the pipe to be attached to the side wall of the underground structure used for the construction of the power wiring to lead the power wiring into the underground structure as needed.

이런, 종래의 관로구 결합구조는 어댑터의 양측 내면에 관로구와 관로구 덮개의 결합을 위한 암나사공을 형성하고, 위 형성된 일측의 암나사공에는 수나사부가 형성된 관로구가 나사결합되도록 하며, 타측의 암나사공에 역시 수나사부가 형성된 관로구 덮개가 나사결합되도록 한 것인데, 상기 구성된 관로구 결합구조는 콘크리트 타설 등의 작업을 통해 어댑터를 지중구조물의 벽체에 설치한 상태에서 어댑터의 양측에 형성된 암나사부에 관로구와 관로구 덮개를 나사결합시키는 것이다.Such a conventional pipe joint coupling structure forms a female threaded hole for coupling of the duct and the pipe cover on both inner surfaces of the adapter, and the female threaded hole formed on the one side of the upper side of the male threaded hole is screwed, and the female threaded hole on the other side as well. The conduit cover formed with a male thread is screwed together. The conduit coupling structure includes screwing the conduit port and the conduit cover to the female threads formed on both sides of the adapter while the adapter is installed on the wall of the underground structure through concrete casting. To combine.

이러한 종래의 관로구 결합구조는 어댑터를 지중구조물의 벽체에 설치하는 과정에서 어댑터 양측의 암나사부에 콘크리트가 들러붙기 때문에 향후 암나사부에 관로구 및 관로구 덮개의 나사결합이 용이하게 이루어지지 않았을 뿐만 아니라, 나사결합상태가 견고하지 않아 관로구 내의 지수성 확보가 어려웠으며 또한, 어댑터와 그 주변에 타설되는 콘크리트의 재질이 서로 다르므로 상호 간에 견고한 부착이 이루어지지 않았고, 경우에 따라서는 어댑터와 그 외부에 타설된 콘크리트 사이로 지중구조물 외부의 물기가 침투되는 등의 문제점이 다수 있었다.In the conventional pipe fitting structure, because the concrete adheres to the female threaded portions on both sides of the adapter in the process of installing the adapter on the wall of the underground structure, screwing of the pipe fittings and the pipe cover is not easily performed in the future. It is difficult to secure the exponential property in the pipeline because it is not tightly coupled. Also, since the material of the adapter and the concrete placed around it is different from each other, it is not securely attached to each other. There have been a number of problems, such as the penetration of water outside the underground structure between concrete.
