Description

사중벽관{fourfold synthetic resin pipe}Four-fold synthetic resin pipe

본 발명은 사중벽관에 관한 것으로, 특히 사중벽관 제조시 발생되는 공간부를 발포성 수지로 채워 강도가 보강된 사중벽관에 관한 것이다.The present invention relates to a quadruple wall tube, and more particularly, to a quadruple wall tube reinforced with strength by filling a space part generated during quadruple wall tube production with a foaming resin.

일반적으로 이중벽관은 통상 비교적 저렴한 폴리에틸렌 등의 수지재로 제조되고, 외벽과 내벽으로 분리되는 격벽구성을 가지며, 상기 외벽과 내벽은 상호 연결될 뿐만 아니라 평행하게 또는 나선형상으로 성형되어, 농수로, 하수관로, 배수관로, 매입관로 등에 내식성이 우수하고, 장시간의 매설시에도 누수가 없어 널리 사용되고 있다.In general, the double wall pipe is usually made of a resin material such as polyethylene, which is relatively inexpensive, has a partition structure that is separated into an outer wall and an inner wall, and the outer wall and the inner wall are not only interconnected but also formed in parallel or in a spiral shape, such as in agricultural water, sewage pipes, It is excellent in corrosion resistance in drainage pipes, buried pipes, etc., and is widely used because it does not leak even when embedded for a long time.

즉, 상기한 바와 같은 종래의 이중벽관은 소정의 직경을 가지는 원통형상 관체로서 폴리에틸렌 등의 수지재로서 금형내에서 성형되고 통상 외벽과 내벽을 가지는 이중벽관으로 구성된다.That is, the conventional double walled tube as described above is a cylindrical tube body having a predetermined diameter, and is formed of a double walled tube formed in a mold by a resin material such as polyethylene and having an outer wall and an inner wall.

상기한 종래의 이중벽관은 이중벽관의 외벽과 내벽간에는 상호 벽체를 연결하는 연결리브가 일체로 성형됨으로써 강도를 보강하고, 이중벽관의 외벽과 내벽간에 형성되는 공간부는 공기가 함입된 부분으로 다각형상체를 구성함으로서 단면계수를 증대하도록 구성된다.The conventional double wall pipe is reinforced between the outer wall and the inner wall of the double wall pipe by integrally forming connecting ribs connecting the mutual walls, and the space formed between the outer wall and the inner wall of the double wall pipe is a polygonal body with the air-impregnated portion. It is configured to increase the section modulus by constructing.

그러나, 상기한 바와 같은 종래의 이중벽관은 주철관이나 콘크리트관에 비하여 내강성 값이 3-6㎏/㎠ 밖에 되지 않아 강성이 약한 문제점을 가지고 있어, 우수한 내식성에도 불구하고 압축강도가 낮음으로서 일정한 깊이 이상 매설할 경우 토압에 내구성이 저하됨으로서 그 사용이 제한되고, 지중매설시 등에는 부압에 의하여 일정한 위치에 매설이 곤란하며, 이중벽관의 내부공간의 존재로 인하여, 부력이 발생되는 수중에는 매설이 어려운 시공상 문제점도 있었다.However, the conventional double walled pipe as described above has a problem that the rigidity value is only 3-6 kg / cm 2 compared with cast iron pipes or concrete pipes, and thus has a weak rigidity. In the case of the above-mentioned embedding, the durability of soil pressure is reduced, and its use is limited.In the case of underground embedding, it is difficult to bury at a certain position by negative pressure. There were also difficult construction problems.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로써, 구조적으로 이중벽관을 개량하여 강도가 향상되며, 시공상 편의성을 추구하도록 한 사중벽관을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a quadruple wall tube that is designed to solve the problems described above, and improves strength by structurally improving the double wall tube, thereby pursuing convenience in construction.

상기한 목적을 달성하기 위한 본 발명에 따른 사중벽관은 속이 빈 중공형상으로 이루어지는 공간부가 형성되며, 합성수지로 소정의 단면형상으로 이루어지는 내측벽관과; 상기 내측벽관의 외측면 전체에 걸쳐서 형성되며, 합성수지로 소정의 단면형상으로 이루어지는 외측벽관으로; 구성됨을 특징으로 한다.The quadruple wall tube according to the present invention for achieving the above object is formed with a hollow hollow shape space portion, the inner wall tube made of a synthetic resin in a predetermined cross-sectional shape; An outer wall tube formed over an entire outer surface of the inner wall tube, the outer wall tube having a predetermined cross-sectional shape with synthetic resin; Characterized in that configured.
