섬유강화플라스틱 이중몸체 지하유류저장탱크{Fiber Reinforced Plastic Double Layer Oil Storing Tank}Fiber Reinforced Plastic Double Layer Oil Storing Tank

본 발명은 지하매설용 유류저장탱크에 관한 것으로, 탱크 내부의 위험물이 누출되는 것을 감지하기 위한 간격을 설정하는 것이 용이하고 탱크의 성형작업이 간편하며 내부몸체와 외부몸체가 일체로 성형되어 서로 분리될 우려가 없으면서 강성이 큰 섬유강화플라스틱 이중몸체 지하유류저장탱크 및 그 제조방법에 관한 것이다.The present invention relates to an oil storage tank for underground laying, it is easy to set the interval for detecting the leakage of dangerous substances inside the tank, easy to form the tank, and the inner body and the outer body are integrally molded and separated from each other The present invention relates to a fiber-reinforced plastic double-body underground oil storage tank having a high rigidity without fear of becoming difficult, and a method of manufacturing the same.

종래 지하매설용 유류저장탱크(이하 '지하유류저장탱크'라 한다)는 강판으로 제조되고 부식에 대응하기 위해 외면에 방청도료를 도장한 강재탱크가 사용되어 왔다. 그러나 지하에 매설되는 관계로 산성토양에 의한 부식 및 전위차에 의한 전기부식 등에 의해 강판이 부식되는 것을 완전히 방지할 수 없어 내용물이 누출되는 사고가 발생하고 있다.Conventionally, underground oil storage tanks (hereinafter referred to as 'underground oil storage tanks') have been used as steel tanks made of steel sheets and coated with rust-preventive coatings on their outer surfaces to cope with corrosion. However, since it is buried underground, corrosion of the steel sheet due to corrosion by acid soil and electric corrosion due to electric potential difference cannot be completely prevented, and the contents leak.

이를 해결하기 위한 방안으로 강판으로 제조된 지하유류저장탱크에 섬유강화플라스틱을 일정간격을 두고 피복시키고 위험물의 누출을 감지하기 위한 설비를 설치한 강재 섬유강화플라스틱 이중몸체탱크(이하 "SF 이중몸체탱크'라 한다)가 개발되었다. SF 이중몸체탱크는 강재탱크에 비해 부식에 대하여 내성을 가지고 있으나 장기간 사용함에 따라 부식으로 인한 핀홀 등이 발생하고 충분한 내식성을 가질 수 없는 것으로 간주되고 있다.To solve this problem, steel fiber reinforced plastic double-body tanks (hereinafter referred to as SF double-body tanks) are coated with fiber-reinforced plastics at regular intervals in steel storage tanks made of steel plates and installed to detect leaks of dangerous goods. SF double body tanks are more resistant to corrosion than steel tanks, but they are considered to have pinholes due to corrosion and not have sufficient corrosion resistance over long periods of use.

이에 섬유강화플라스틱으로 제조한 지하유류저장탱크에 섬유강화플라스틱을 일정간격을 두고 피복시키고 또한 위험물의 누출을 감지하기 위한 설비를 설치한 섬유강화플라스틱 이중몸체탱크(이하 'FF 이중몸체탱크'라 한다)가 개발되었다. FF 이중몸체탱크는 탱크 내부의 위험물이 누출되는 것을 감지하기 위하여 간격을 설정하는 것이 곤란하기 때문에 생산성이 저하되는 문제가 있다.The fiber-reinforced plastic double-body tank (hereinafter referred to as 'FF double-body tank') is coated with fiber-reinforced plastic at regular intervals in the underground oil storage tank made of fiber-reinforced plastic and installed to detect leaks of dangerous goods. ) Was developed. FF dual body tank has a problem that productivity is reduced because it is difficult to set the interval to detect the leakage of dangerous goods inside the tank.

이를 해결하기 위하여 대한민국 특허 제172106호 'FRP 탱크의 이중원통몸체'가 제안되었다. 이 특허는, 도 3에 도시된 바와 같이, 섬유강화플라스틱으로 된 내부몸체(1)와, 섬유강화플라스틱으로 된 외부몸체(2)와, 상기 외부몸체(2)의 외주에 설치되는 보강리브(3)와, 상기 내부몸체(1)와 외부몸체(2) 사이에 설치되는 열가소성 플라스틱 소재의 시트(4)와, 상기 외부몸체(2)와 시트(4) 사이에 설치되는 필름(5)을 포함하고 있으며, 상기 열가소성 플라스틱 소재의 시트(4)는 상기 내부몸체(1)가 갖는 곡률과 같은 곡률로 되어 있으면서 그 표면상에 요철(4a)을 갖는 구성이다. 그리고 누출감지장치의 감지기(6)의 선단부가 내부몸체(1)와 외부몸체(2) 사이의 간격층에 위치하도록 설치되어 있다. 그러나 이 특허는 요철이 형성된 열가소성 플라스틱 시트와 필름을 성형하고 이를 내부몸체와 외부몸체 사이에 적층 성형하므로 작업성이 떨어지고 장기간 사용함에 따라 열가소성 플라스틱 시트와 필름의 접합면이 파괴되어 내부몸체와 외부몸체가 서로 분리될 수 있다는 우려가 있다.In order to solve this problem, Korean Patent No. 172106 'Double Cylindrical Body of FRP Tank' has been proposed. As shown in Fig. 3, the patent discloses an inner body 1 made of fiber-reinforced plastics, an outer body 2 made of fiber-reinforced plastics, and a reinforcing rib provided on the outer circumference of the outer body 2 ( 3) and a sheet 4 of thermoplastic material installed between the inner body 1 and the outer body 2 and the film 5 provided between the outer body 2 and the seat 4. The sheet 4 of the thermoplastic material is configured to have the same curvature as the curvature of the inner body 1 and to have the unevenness 4a on its surface. And the front end of the detector 6 of the leak detection apparatus is provided so that it may be located in the space | interval layer between the inner body 1 and the outer body 2. However, this patent forms a thermoplastic plastic sheet and a film having irregularities, and laminates it between an inner body and an outer body, thus reducing workability and destroying the bonding surface of the thermoplastic sheet and the film due to long-term use. There is a concern that can be separated from each other.

본 발명은 이러한 사정을 감안하여 안출된 것으로, 탱크 내부의 위험물이 누출되는 것을 감지하기 위한 간격을 설정하는 것이 용이하고 탱크의 성형작업이 간편하며 내부 몸체와 외부 몸체가 일체로 성형되어 서로 분리될 우려가 없는 섬유강화플라스틱 이중몸체 지하유류저장탱크 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention has been devised in view of such circumstances, it is easy to set the interval for detecting the leakage of dangerous goods inside the tank, the molding operation of the tank is easy and the inner body and the outer body are integrally molded and separated from each other An object of the present invention is to provide a fiber reinforced plastic double-body underground oil storage tank and a method of manufacturing the same.

그리고 상기 내부 몸체와 외부 몸체 사이에는 탱크내부의 유류 누출을 감지하는 누출감지장치의 감지기 선단부가 위치하도록 설치될 수 있다.And between the inner body and the outer body may be installed so that the detector tip of the leak detection device for detecting the oil leakage in the tank.

본 발명의 다른 적절한 실시형태에 따르면, 모터에 의해 회전하는 맨드렐에 합성수지가 함침된 보강섬유를 감고, 그 위에 합성수지가 함침된 적어도 1종류 이상의 골재 혼합물을 투입한 후, 합성수지가 함침된 보강섬유를 다시 감은 다음 경화시키는 것을 특징으로 하는 섬유강화플라스틱 이중몸체 지하유류저장탱크의 제조방법이 제공된다.According to another suitable embodiment of the present invention, after reinforcing fibers impregnated with synthetic resin on a mandrel rotated by a motor, at least one aggregate mixture impregnated with synthetic resin is added thereto, and then the reinforcing fibers impregnated with synthetic resin Provided is a method for manufacturing a fiber-reinforced plastic double-body underground oil storage tank, which is characterized by rewinding and curing.

본 발명에 따르면 내부 몸체와 외부 몸체 사이에 합성수지에 함침된 골재를 채움으로서 골재 사이의 공극으로 내부의 위험물이 누출되는 것을 감지하기 위한 간격을 설정하는 것이 용이하다.According to the present invention it is easy to set the interval for detecting the leakage of the dangerous goods inside the gap between the aggregate by filling the aggregate impregnated in the synthetic resin between the inner body and the outer body.

또한, 내부 몸체와 외부 몸체가 합성수지에 함침된 골재를 매개로 일체로 성형되므로 서로 분리될 우려가 없고 강성이 크다. In addition, since the inner body and the outer body are integrally molded through the aggregates impregnated in the synthetic resin, there is no fear of separation from each other and the rigidity is large.

이하 본 발명의 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시 예에 따른 섬유강화플라스틱 이중몸체 지하유류저장탱크를 나타낸 단면도이고, 도 2는 본 발명의 다른 실시 예에 따른 섬유강화플라스틱 이중몸체 지하유류저장탱크를 나타낸 단면도이다.1 is a cross-sectional view showing a fiber-reinforced plastic double body underground oil storage tank according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a fiber-reinforced plastic double body underground oil storage tank according to another embodiment of the present invention.

도시된 바와 같이 본 발명에 따른 지하유류저장탱크는 섬유강화플라스틱으로 된 내부 몸체(10)와, 섬유강화플라스틱으로 된 외부 몸체(20) 그리고 그 사이에 충전되는 합성수지에 함침된 적어도 1종류의 골재로 구성된 채움재(30)를 포함한다.As shown, the underground oil storage tank according to the present invention has at least one aggregate impregnated with an inner body 10 made of fiber reinforced plastic, an outer body 20 made of fiber reinforced plastic, and a synthetic resin filled therebetween. It comprises a filling material 30 composed of.

내부 몸체(10)와 외부 몸체(20)는 모두 보강섬유에 합성수지를 함침한 섬유강화플라스틱으로 구성된다. 섬유강화플라스틱을 구성하는 보강섬유로는 탄소섬유, 유리섬유, 아라미드섬유 등이 사용될 수 있으며 합성수지로는 에폭시수지, 페놀수지, 폴리에스테르수지 등이 사용될 수 있다. 그리고 내부 몸체(10)와 외부 몸체(20)는 모두 맨드렐 위에서 연속식 필라멘트 와인딩 공법으로 성형된다.Both the inner body 10 and the outer body 20 are made of fiber-reinforced plastics impregnated with synthetic resin in the reinforcing fibers. Carbon fiber, glass fiber, aramid fiber, etc. may be used as reinforcing fibers constituting the fiber-reinforced plastic, and synthetic resins may include epoxy resins, phenol resins, polyester resins, and the like. And both the inner body 10 and the outer body 20 are molded by a continuous filament winding method on the mandrel.

채움재(30)로는 합성수지에 함침된 적어도 1종류의 골재(31)를 혼합한 것을 사용한다. 이렇게 내부 몸체(10)와 외부 몸체(20) 사이에 골재(31)를 채움으로써 내부의 위험물이 누출되는 것을 감지하기 위한 간격을 설정하는 것이 용이하게 된다. 골재로는 동일한 입도를 갖는 1종류의 골재만을 사용할 수도 있으나 탱크의 강 성 등을 고려하여 입도 분포가 불량한 적어도 2종류 이상의 골재를 혼합한 것을 사용할 수도 있다. 한편 골재는 합성수지에 함침된 것이므로 다수의 공극을 유지하면서 서로 결합되고 그에 따라 내부 몸체(10)와 외부 몸체(20)가 서로 일체구조가 되도록 하여 탱크 전체의 강성이 커지게 된다. 즉, 종래와 같이 외부 몸체의 외부에 별도로 리브를 형성할 필요가 없게 된다(도 3 참조).As the filler 30, a mixture of at least one aggregate 31 impregnated with a synthetic resin is used. By filling the aggregate 31 between the inner body 10 and the outer body 20 in this way it is easy to set the interval for detecting the leakage of the dangerous goods inside. As aggregate, only one type of aggregate having the same particle size may be used, but a mixture of at least two or more types of aggregates having poor particle size distribution may be used in consideration of the rigidity of the tank. On the other hand, the aggregate is impregnated in the synthetic resin, so that it is coupled to each other while maintaining a plurality of voids, thereby increasing the rigidity of the entire tank by making the inner body 10 and the outer body 20 integral with each other. That is, it is not necessary to form a rib on the outside of the outer body as in the prior art (see Fig. 3).

그리고 도 2에 도시된 바와 같이 탱크내부의 유류 누출을 감지하는 누출감지장치는 그 감지기(40)의 선단부가 내부 몸체(10)와 외부 몸체(20) 사이에 위치하도록 설치된다.And the leak detection device for detecting the oil leakage in the tank as shown in Figure 2 is installed so that the front end of the detector 40 is located between the inner body 10 and the outer body 20.

이상과 같이 구성된 본 발명에 따른 지하유류저장탱크의 제조방법은 다음과 같다.The manufacturing method of the underground oil storage tank according to the present invention configured as described above is as follows.

모터에 의해 회전하는 맨드렐에 합성수지가 함침된 보강섬유를 감고, 그 위에 합성수지가 함침된 적어도 1종류 이상의 골재 혼합물을 투입한 후, 합성수지가 함침된 보강섬유를 다시 감은 다음 경화시키면 된다. 즉, 본 발명에 따른 지하유류저장탱크는 필라멘트 와인딩 공법으로 성형된다.The reinforcing fiber impregnated with synthetic resin is wound on the mandrel rotated by the motor, and at least one aggregate mixture impregnated with the synthetic resin is added thereto, and then the reinforcing fiber impregnated with the synthetic resin is rewound and then cured. That is, the underground oil storage tank according to the present invention is formed by a filament winding method.
