Description

보강된 이중벽관체Reinforced Double Wall Pipe

본고안은 보강된 이중벽관체에 관한 것으로서, 더욱 상세히는 각종의 매설관체등으로 사용되는 이중벽관체의 구성의 개선에 관한 것이다.The present invention relates to a reinforced double wall pipe body, and more particularly, to an improvement in the configuration of a double wall pipe body used in various buried pipes and the like.

외벽과 내벽으로 분리되는 격벽구성을 가지고 외벽과 내벽은 상호 연결되면서 평행하게 또는 스파이럴형상으로 관체로서 성형되는 이중관체는 다양한 용도, 예를들면, 농수로, 하수관로, 배수관로, 매입관로등으로 널리 사용되고 있고 이러한 이중관체는 통상, 비교적 저렴한 폴리에틸렌등의 수지재로서 일관되게 성형된다.The double pipes, which are divided into the outer wall and the inner wall, and the outer wall and the inner wall are interconnected and formed in parallel or spiral shape as tubular bodies, are widely used in various applications, for example, agricultural water passages, sewer pipes, drainage pipes, buried pipes, etc. These double tubes are usually molded consistently as resin materials such as relatively inexpensive polyethylene.

상기하는 폴리에틸렌수지재의 이중벽관체는 내식성이 우수하고, 그에따라서 장시간의 매설사용시에도 누수가 없어 널리 사용되고 있지만 종래의 주철관이나 콘크리트관에 비하여 내강성값이 3 - 6㎏/㎠ 밖에 되지 않아 강성이 약한 문제점을 가지고 있었다. 따라서 보강관체나 보강구조물이 요구되는 등의 문제점으로 인하여 우수한 내식성에도 불구하고 그 사용처가 제한될 수밖에 없었고 내부공간의 존재로 인한 부력의 발생으로 수중매설이 어려운 등의 시공상의 문제점 또한 상존하였다.The double-walled tubular body of the polyethylene resin material is excellent in corrosion resistance, and therefore is widely used because it does not leak even when used for a long time, but the rigidity value is 3-6 kg / ㎠ as compared to the conventional cast iron pipe or concrete pipe. Only stiffness had a weak problem. Therefore, due to problems such as the need for reinforcing pipes or reinforcing structures, their use was limited despite the excellent corrosion resistance, and construction problems such as buried buoyant due to the existence of internal spaces were difficult.

본고안의 보강된 이중벽관체는 상기한 종래 통상적인 구성의 이중벽관체의 문제점을 감안하여 간단한 공정의 추가로서 제일의 문제점인 강성을 보강함으로서 그 사용처를 대폭 증대하는 등의 유용성을 가지는 것을 목적으로 한다.The reinforcement double wall tube body of the present invention has the purpose of having usefulness such as greatly increasing the use place by reinforcing the rigidity which is the first problem by adding a simple process in view of the problems of the above-described conventional conventional double wall tube body.

상기하는 목적을 달성하기 위한 본고안의 보강된 이중벽관체는;Reinforced double wall tube of the present invention for achieving the above object;

폴리에티렌등의 수지재로서 외벽면부와 내벽면부및 연결리브부를 평행하게 또는 스파이럴형상으로 구비하는 이중벽관체를 구성함에 있어서;In constructing a double wall tube body having a resin material such as polystyrene and having an outer wall surface portion, an inner wall surface portion and a connecting rib portion in parallel or in a spiral shape;

이이이이하의 이하의 부수된 도면과 함께 본고안의 보강된 이중벽관체의 구성및 작용효과를 상세하게 설명한다.The construction and effect of the reinforced double walled tube of the present invention will be described in detail together with the following accompanying drawings.

도 1 은 본고안의 보강된 이중벽관체가 적용되는 통상적인 구성의 폴리에틸렌등의 이중벽관을 예시적으로 도시하는 사시도, 도 2 는 종래 구성의 폴리에티렌이중벽관을 도시하는 도 1 의 A-A 선을 따라 취한 단면도, 도 3 은 본고안의 구성의 폴리에티렌이중벽관을 도시하는 도 1 의 A-A 해당부의 예시적인 단면도이다.1 is a perspective view exemplarily showing a double wall tube of a polyethylene or the like in a conventional configuration to which the reinforced double wall tube body of the present invention is applied, and FIG. 2 is a line along the AA line of FIG. 3 is an exemplary cross-sectional view of the AA corresponding part of FIG. 1 showing the polystyrene double walled tube of the configuration of the present invention.

도 1 내지 2 도에 도시되는 바와 같이,As shown in Figs.

종래의 통상적인 구성의 이중벽관체(10)는 소정의 직경을 가지는 원형상의 관체로서 폴리에틸렌등의 수지재로서 금형내에서 성형되고 통상 외벽면부(11)와 내벽면부(12)를 가지는 이중벽체의 관체로서 구성된다. 이러한 구성이 도 2 에 도시되며 도 1 의 A-A 선단면도중 평행한 부분중 하나의 부분만을 도시하고 있다.The conventional double wall tube body 10 is a circular tube body having a predetermined diameter. The double wall tube body is molded in a mold as a resin material such as polyethylene, and has a double wall body body having an outer wall face portion 11 and an inner wall face portion 12. It is configured as. This configuration is shown in FIG. 2 and shows only one of the parallel parts in the A-A cross-sectional view of FIG.

상기하는 이중벽관체(10)의 외벽면부(11)와 내벽면부(12)사이는 상호 벽면체를 연결하는 연결리브부(13)가 역시 일체로서 성형됨으로서 강도를 보강하고,Between the outer wall surface portion 11 and the inner wall surface portion 12 of the double-walled pipe body 10, the connecting rib portion 13 connecting the mutual wall surface body is also formed integrally to reinforce the strength,

이중벽관체(10)의 외벽면부(11)와 내벽면부(12)사이에 형성되는 공간부(G)는 공기가 함입된 부분으로서 개략 다각형상체를 구성함으로서 단면계수(Sectional Coefficient)를 증대하도록 구성되어 있다.The space portion G formed between the outer wall surface portion 11 and the inner wall surface portion 12 of the double wall pipe body 10 is configured to increase the section coefficient by forming a coarse polygonal body as a portion containing air. have.

이러한 이중벽관체(10)는 평행한 절곡체 또는 스파이럴형상등으로 일관되게 제조된다.Such a double wall tube body 10 is consistently produced in parallel bent body or spiral shape.

상기의 종래로부터의 이중벽관체는 경량이면서도 내식성이 높아 다양한 용도로서 사용되지만 상술한 바와 같이, 압축강도가 낮음으로서 일정한 깊이이상 매설할 경우 토압(土壓)에 대한 내구성이 저하됨으로서 그 사용이 제한되고, 또한 지중매설시등에는 부압(浮壓)에 의하여 일정한 위치에 매설이 곤란한 등의 문제점이 있었다.The conventional double wall pipe body is light weight and has high corrosion resistance and is used for various purposes. However, as described above, when the buried material is buried more than a certain depth due to low compressive strength, its use is limited. In addition, there was a problem in that it was difficult to bury at a certain position due to negative pressure during underground laying.

종래 구성의 이중벽관체의 문제점을 감안한 본고안의 보강된 이중벽관체를 도 3 과 함께 설명한다.The reinforcement double wall tube body of this paper which considered the problem of the double wall tube body of a conventional structure is demonstrated with FIG.

본고안의 보강된 이중벽관체는 도시하는 바와 같이,As shown, the reinforced double wall tube body

이중벽관체(10)의 외벽면부(11)와 내벽면부(12) 및 연결리브부(13)사이에 형상되는 공간인 공간부(G)에 불포화 폴리에스텔수지(FRP)(20)를 충진하되,Fill the unsaturated polyester resin (FRP) (20) in the space portion (G) which is a space formed between the outer wall surface portion 11, the inner wall surface portion 12 and the connecting rib portion 13 of the double wall pipe body 10,

충진시에 불포화 폴리에스텔수지(20)에 부가하여 쇄석등으로부터의 모래, 자연사, 길이가 짧은 유리섬유와 같은 무기물충진재(21)와 기타 분쇄된 고형물을 혼입한 충진보강재(22)를 혼합하여 주입한다.In filling, the filler is mixed with the inorganic filler 21 such as sand, natural sand, short glass fibers from the crushed stone, and the filler reinforcement 22 mixed with other pulverized solids. do.

불포화폴리에스텔 대용으로 우레탄수지등을 대용할 수있음은 물론이다.Of course, the urethane resin can be substituted for the unsaturated polyester.

이러한 주입은 금형으로부터 이중벽관체(10)과 성형되어 나오면서 즉시, 또한 냉각후에 펌프등으로 상기의 공간부(G)에 강제주입하여 성형되는 것이 일반적인 공정일 것이다.Such injection may be generally performed by forcibly injecting the double wall tube body 10 from the mold into a space G immediately after being cooled, and by cooling the pump with a pump or the like after cooling.

이상과 같이 구성되는 본고안의 보강된 이중벽관체는,Reinforced double wall pipe of this article comprised as mentioned above,

종래 공간부로서 존재하던 이중벽관체(10)의 외벽면부(11)와 내벽면부(12) 및 연결리브부(13)사이에 형성되는 공간부(G)를 무기물 및 충진재로서 혼합하여 충진하는 것은 저렴한 비용으로서 이를 수행할 수있음으로서 강성이 대폭 증대되어 다양한 용도로서 사용될 수있으며,It is inexpensive to mix and fill the space G formed between the outer wall 11, the inner wall 12, and the connecting rib 13 of the double wall tubular body 10, which has existed as a space, as an inorganic material and a filler. By doing this as a cost, the rigidity can be greatly increased and used for various purposes.

또한, 토압에 대한 내압성이 증대되어 매설깊이를 증대할 수있고 물의 비중이하로서 관체의 중량이 형성되므로 수중매설 또는 농수로등으로의 매설시의 작업이 용이하게 되면서도 종래의 특징인 내식성을 그대로 유지할 수있게 되는 등의 다양한 작용상의 효과를 가지게 되는 것이다.In addition, since the pressure resistance against earth pressure can be increased, the depth of embedding can be increased, and the weight of the tubular body is formed as the specific gravity of water, so that it is easy to work in underwater laying or laying in agricultural waterways, while maintaining the corrosion resistance which is a conventional feature. It will have a variety of effects such as being.

하수관로로서 사용하는 경우, 종래의 철판을 매입한 콘크리트관(P.C.)대신 저렴하게 사용할 수있게 되는 유용성을 가진다.When used as a sewage pipe, it has the utility that it can be used cheaply instead of the concrete pipe (P.C.) which embeds the conventional iron plate.

이상과 같은 본고안의 보강된 이중벽관체는 극히 저렴한 비용으로서 강도를 대폭 보강하게 함으로서 종래의 이중벽관체가 가지던 결점을 대부분 해소하게 함으로서 그 사용처를 대폭 증대하고 고가의 철판매입콘크리드등을 대용하게 하는 경제성을 가지는 유용한 고안인 것이다.The reinforcement double wall pipes in this paper can greatly reinforce the strength at a very low cost, and solve most of the shortcomings of the conventional double wall pipes, thereby greatly increasing its use and substituting expensive steel sales concrete. It is a useful design with economics.
