Description

이중구조를 가지는 매설관 및 그의 제조방법{Double lay pipe and manufacturing method thereof}Buried pipe having a double structure and a manufacturing method thereof

본 발명은 지중에 매설되어서 상,하수를 통수시켜 주는 매설관에 관한 것으로, 특히 이질의 파형강관과 평활합성수지관을 일체화시켜서 우수한 구조적강도와 통수능력을 발휘하게 하여 주는 이중구조를 가지는 매설관 및 그의 제조방법에 관한 것이다.The present invention relates to a buried pipe that is buried in the ground to pass water and sewage, and in particular, a buried pipe having a dual structure to unify heterogeneous corrugated steel pipes and smooth synthetic resin pipes to exhibit excellent structural strength and water-permeability. It relates to a manufacturing method thereof.

이전의 매설관은 역학적으로 큰 하중이나 토압을 감당할 수 있도록 콘크리트 또는 주철관이 주로 사용되어 왔다. 이와 같은 콘크리트관 또는 주철관은 토압이나 하중에 대응하는 구조적강도가 우수한 장점을 가지는 것이 사실이나, 재질적인 특성상 중량이어서 무게부담이 큰 만큼 취급 및 시공성이 매우 불량한 등의 문제점을 가지는 것으로 알려져 있다.Previously, buried pipes have been mainly used for concrete or cast iron pipes to mechanically handle large loads or earth pressures. Such concrete pipes or cast iron pipes have the advantage of excellent structural strength corresponding to earth pressure and load, but are known to have problems such as poor handling and workability due to their heavy weight due to their material properties.

최근에 상기한 이전의 매설관들이 가지는 문제점을 해결하고자 파형강관이 개발되어서 제공되고 있다. 이러한 파형강관은 단위무게가 상대적으로 경량인 강판을 소재로 하여 힘살의 역할을 하는 나선파형들이 원주방향으로 굴곡지게 만들어져서, 이전의 콘크리트관 또는 주철관 등의 매설관과 대등한 구조적강도를 발휘할뿐만 아니라, 무게부담을 줄여주어서 취급 및 시공성이 우수한 장점을 가지는 것이 사실이다.Recently, corrugated steel pipes have been developed and provided to solve the problems of the aforementioned buried pipes. These corrugated steel pipes are made of steel plate with relatively light weight, so that the spiral waveforms acting as a force can be bent in the circumferential direction. Rather, it has the advantage of excellent handling and workability by reducing the weight burden.

그러나, 이와 같은 파형강관은 원주방향으로 나선파형들이 반복되어서 상,하수의 흐름방향에 대하여 거의 직각으로 굴곡져 있는 점을 감안하여 볼 때, 상,하수의 정상적인 흐름을 방해하는 역기능을 가지게 됨으로써, 결과적으로 내부를 따라 흐르는 상,하수가 원활하게 통수되지 못하는 문제점이 있었다. 또한, 파형강관은 강판을 소재로 하여 만들어지고 내부를 따라 흐르는 상,하수와 상시적으로 접촉하게 됨으로써, 부식이 촉진되어서 사용수명이 크게 단축되는 문제점 등이 있었다.However, in view of the fact that such spiral steel pipes are circumferentially spiraled in a circumferential direction and bent almost perpendicularly to the flow direction of the sewage and sewage, the corrugated steel pipe has a reverse function that obstructs normal flow of water and sewage. As a result, there was a problem that the water flows along the inside, sewage can not flow smoothly. In addition, the corrugated steel pipe is made of a steel sheet and is in constant contact with water and sewage flowing along the inside, thereby promoting corrosion and greatly shortening the service life.

본 발명의 목적은 이질의 파형강관 내에 평활합성수지관이 일체화되도록 설치 구성하여서, 첫째 외적인 하중 및 충격에 대응하는 구조적강도가 더욱 증대된 매설관을 제공하는 데 있으며, 둘째 내부에 흐르는 상,하수에 대한 통수능력이 향상된 매설관을 제공하는 데 있으며, 셋째 상,하수에 의한 부식의 염려를 해소하여서 내구성이 향상된 매설관을 제공하는 데 있다.An object of the present invention is to provide a smooth composite resin pipe is integrated in the heterogeneous corrugated steel pipe, firstly to provide a buried pipe with a further increased structural strength in response to external loads and impacts, and secondly In order to provide a buried pipe with improved water permeability, and thirdly, it is to provide a buried pipe with improved durability by eliminating the fear of corrosion caused by water and sewage.

Third, it has the advantage of extending the overall service life by blocking the upper and sewage, which causes the corrosion, from contacting the corrugated steel pipe.

이하, 첨부도면에 도시되는 구체적인 실시예를 통하여 본 발명의 기술내용을 상세히 설명하면 다음과 같다.Hereinafter, the technical details of the present invention through the specific embodiments shown in the accompanying drawings in detail.

상기 파형강관(10)은 복수개의 파형들이 형성된 강판(11)의 양측단이 걸고리 (12)로 연이어지는 원통체로 나선권회되어서 그 원주방향으로 복수개의 나선파형 (10a)들이 1개조로 하여 반복적으로 굴곡지게 형성된 것이면 족하다.The corrugated steel pipe 10 is spirally wound into a cylindrical body in which both ends of the steel plate 11 having a plurality of corrugations formed are connected to the hook 12 so that a plurality of spiral waveforms 10a are repeatedly formed in the circumferential direction thereof. It is sufficient if it is formed to be bent.

본 발명의 실시예에서 상기 파형강관(10)은 복수개의 파형들이 형성된 강판 (11)을 소재로 하여서 된 것으로 예시되어 있으나, 이러한 파형강관(10)은 도3의 도시와 같이 복수개의 파형들이 형성된 강판의 내,외표면이 합성수지로 피복된 코팅강판(13)을 소재로 하여서, 그 파형강관(10) 자체의 내식성을 증대시켜 주면서도 상기 채움접합수지(40)를 매개로 하여 접합되는 평활합성수지관(20)과의 일체성을 증대시키는 데 도움이 되도록 할 수도 있음을 밝혀 둔다.In the exemplary embodiment of the present invention, the corrugated steel pipe 10 is illustrated as being made of a steel plate 11 having a plurality of corrugations formed therein, but the corrugated steel pipe 10 is formed with a plurality of corrugations as shown in FIG. 3. Made of coated steel sheet 13 coated with synthetic resin on the inner and outer surfaces of the steel sheet, the corrugated steel pipe 10 is joined to the filling joint resin 40 while increasing the corrosion resistance of the corrugated steel pipe 10 itself.
