Description
본 발명은 플랜지에 의해 결합되는 3중벽 하수관에 관한 것으로서, 보다 상세하게는 PE와 EVA 및 강철핀을 혼합 후 압출 성형하여 2중벽관을 제조하고, 상기 2중벽관에 다시 용수철이나 용접철망을 감은 후 PE를 융착접착하여 제조된 3중벽관과, 상기 3중벽관의 단부에 결합되고 내부에 돌출부와 삽입부가 형성되어 서로 맞물려 결합될 수 있도록 하는 플랜지로 구성되어, 강철핀과 용수철 및 용접철망에 의해 하중에 대한 변형이 적고 지지력이 뛰어나며, 유연성이 뛰어나 동절기에 쉽게 파손되지 않고, 플랜지의 내부에 다수개의 삽입홈과 돌출부가 형성되어 결합시 삽입홈과 돌출부에 의해 서로 맞물려 결합됨으로서 관의 접합시에 플랜지의 결착력이 좋아 물의 누수를 방지하고 관의 접합이 간단하여 노무자의 피로가 덜하여 노무비가 절감되는 플랜지에 의해 결합되는 3중벽 하수관에 관한 것이다.The present invention relates to a triple wall sewage pipe coupled by a flange, and more particularly, a double wall pipe is manufactured by mixing and extruding PE, EVA, and steel pins, and wound springs or welded wire meshes on the double wall pipe again. After the triple wall pipe manufactured by fusion-bonding PE, and a flange that is coupled to the end of the triple wall pipe and is formed inside the protrusion and the insertion portion to be engaged with each other, the steel pin and the spring and the welded wire mesh Due to the small deformation of the load, excellent bearing capacity, and excellent flexibility, it is not easy to be damaged in winter, and a plurality of insertion grooves and protrusions are formed inside the flange and are coupled to each other by the insertion grooves and protrusions when joining the pipes. The flange's fast binding force prevents water leakage and the pipe is simple to reduce labor costs by reducing labor fatigue. It relates to a triple wall sewer pipe coupled by.
일반적으로 하수관은 아연도금강판을 소재로 하는 파형강관과 PE소재의 이중벽관으로 분류되며, 이러한 이중벽관은 시공시 이중벽관의 관결합을 위해 결합부위에 해당되는 두개의 이중벽관의 양단에 플랜지를 결합한 뒤 볼트로 체결하는 방식을 사용하였으나 상기의 플랜지는 내부에 원형의 돌출부와 삽입홈이 없고 단순히 접합면을 맞대어 볼트로 조여지는 구조로 되어 있어 외부 충격이나 하중이 가해질시 접합면으로 누수가 되거나 절단되는 문제가 있다.In general, sewage pipes are categorized into corrugated steel pipes made of galvanized steel and double wall pipes made of PE. These double wall pipes have flanges at both ends of two double wall pipes corresponding to the joint for pipe joints during construction. The flange is fastened by bolts after joining, but the flange has no circular protrusions and insertion grooves inside and is simply tightened with bolts against the joint surface. There is a problem of cutting.
또한 접합시트를 이용하여 하수관을 연결하는 방법으로는 연결되어지는 2개관의 연결부에 열선이 깔린 접합시트를 감은 후 접합시트의 열선에 전원을 공급하여 열선의 발열에 의하여 융착되도록 하였으나 상기의 방법은 전기 융착기를 시공현장에 준비하고 있거나 자가 발전장치가 있어야 하므로 전기가 없는 장소에서는 사용이 어렵고, 시공현장이 우천이나 다습한 곳 또는 영하의 날씨 등 기후의 심한 경우에는 감전의 위험성이 많고 작업자의 숙련된 기술이 필요하며 작업공수가 복잡한 문제점이 있었다.In addition, as a method of connecting sewage pipes using a bonding sheet, a bonding sheet coated with a heating wire is wound on two connecting pipes to be connected, and power is supplied to the heating wire of the bonding sheet to be fused by heating of the heating wire. It is difficult to use in places without electricity because the electric welding machine is prepared at the construction site or there must be a self-generating device.In case of severe weather such as rainy or humid place or sub-zero weather, there is a high risk of electric shock. There was a need for advanced technology and complicated labor.
그리고, PE만으로 하수관을 제조하였기 때문에 하수관에 하중에 강하지 못하여 변형이 쉽게 생기고, 유연성이 적어 특히 동절기 작업시 관을 운반시나 관에 충격이 가해질시에 크랙이 자주 발생하는 문제점이 있었다. In addition, since the sewage pipe was manufactured using only PE, the sewage pipe was not strong to load, so deformation was easily generated, and there was a problem that cracks were frequently generated when transporting the pipe or applying a shock to the pipe during the winter operation.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출되는 것으로, PE와 EVA(에틸렌 아세트산 비닐공중합체) 및 강철핀을 혼합하여 2중벽관을 제조하고, 상기 2중벽관에 다시 용수철이나 용접철망을 감은 후 PE를 융착접착함으로서 강철핀과 용수철 및 용접철망에 의해 하중에 대한 변형이 적고 지지력이 뛰어나며, 유연성이 좋아 동절기에 쉽게 파손되지 않으며, 상기 3중벽관에 결합되는 플랜지의 내부에 다수개의 삽입홈과 돌출부가 형성되어 삽입홈과 돌출부에 의해 서로 맞물려 결합되는 구조로서 플랜지 결착력이 좋아 물의 누수가 없으며 조립이 간편하여 노무자의 피로가 덜하고 노무비가 절감되는 플랜지에 의해 결합되는 3중벽 하수관을 제공함을 목적을 한다.The present invention is devised to solve the conventional problems as described above, to produce a double wall pipe by mixing PE and EVA (ethylene vinyl acetate copolymer) and steel pins, the spring or welded wire mesh again in the double wall pipe After welding, PE is fusion-bonded, so that the deformation of the load is small and the bearing capacity is excellent due to the steel pin, the spring, and the welded wire mesh, and the flexibility is not easy to be broken in winter. The insertion groove and the protrusion are formed to be engaged with each other by the insertion groove and the protrusion, and the flange binding power is good, and there is no leakage of water, and the assembly is simple, which makes the triple wall sewer pipe coupled by the flange, which reduces laborer's fatigue and reduces labor costs. The purpose is to provide.
