Abstract

A protective pipe for an underground cable is provided to protect the underground cable by preventing the deformation of a joint due to the temperature variation. Front and rear protective pipe bodies(10,10a) are connected separately by a connection pipe(20). A connection pipe connects the pipe bodies in the separated state. Front and rear sealing tray rings are fixed in the front and rear sides of the connection pipe and seals hermetically. An arch elastic member(40,40a,40b) pulls and reduces the interval of the front and rear protective pipes by the elasticity. A separation preventing stand(50) prevents the excessive separation of the front and rear protective pipe.

Description

지중케이블 보호관{Protective pipe for underground cable}Protective pipe for underground cable

본 발명은 지중케이블 보호관에 관한 것으로서, 보다 상세하게는 무더운 여름철이나 겨울철의 기온변화에 따른 신축이 발생되어도 그로 인한 이음연결부의 변형이 일어나지 않아 보다 효과적으로 지중 케이블을 보호할 수 있는 지중케이블 보호관에 관한 것이다. The present invention relates to an underground cable protective tube, and more particularly, to the underground cable protective tube that can protect the underground cable more effectively, even if the expansion occurs due to the temperature change in the hot summer or winter season does not cause deformation of the joint connection will be.

일반적으로 우리나라의 가공배전선지중화는 1973년 효자동에서 광화문구간까지 복잡하게 시설되어 있는 배전선을 전선 정비측면에서 간선도로변의 전주를 뒷골목에 이설, 저압케이블을 사용 주상변압기로부터 인근 수용가를 공급함으로써 시작되었으며, 그 이후 다음과 같이 계획되어 확장되고 있다.In general, Korea's overhead distribution line processing began in 1973 by distributing complex distribution lines from Hyo Auto to Gwanghwamun, relocating electric poles along the main road to the back alley in the aspect of cable maintenance, and supplying nearby customers from low-voltage cables using low voltage cables. Since then, it has been planned and expanded as follows.

참고로 지중 선로 공사방식은 크게 직매식과, 관로식 그리고, 전력구식으로 나눌 수 있다. 여기서, 관로식은 합성수지관, 강관, 흄관 등 관재(pipes)를 사용하여 관로를 구성한 후 케이블을 부설(敷設)하는 방식으로써, 일정 거리의 관로 양끝에는 맨홀을 설치하여 케이블을 설치하고 접속한다.For reference, underground construction works can be divided into direct sales, pipelines, and electricity. Here, the pipeline type is a method of laying a cable after pipes are constructed using pipes such as synthetic resin pipes, steel pipes, and fume pipes, and a manhole is installed at both ends of the pipes at a predetermined distance to install and connect the cables.

이러한, 관로식 공사에 사용되는 관로는 케이블 회선수가 3회선 이상 9회선 미만이거나, 장래 회선증설이 예상되는 경우에, 도로예정지역으로 도로포장계획이 있는 경우에, 직매식이 불리한 경우에, 합성수지관, 강관, 흄관 등과 같은 관재(pipes)가 주로 이용되었는데, 이러한 관재는 지금까지 매우 단순한 형태로 제작되어 있어 실사용시 여러 가지의 문제점을 제공하였는바, 첫째로는 단순히 관재 상호간을 볼트와 너트로 체결하여 관로를 형성함에 따라, 초기 관로 상태를 장기간 견고히 유지할 수 없는 문제점이 있었다. 즉, 상술한 바와 같이 관재의 연결을 단순히 볼트와 너트를 사용하여 연결하고 있으므로 실사용시 토압에 의해 상호간의 연결부위가 단락되는 현상이 자주 초래되었기 때문이다.Such pipes used for pipeline construction are synthetic resin pipes when direct cable type is unfavorable when the number of cable lines is more than 3 lines or less than 9 lines, or when the line expansion plan is expected in the future, when there is a road paving plan in the planned area. Pipes such as steel pipes and fume pipes were mainly used, and these pipes have been manufactured in a very simple form so that various problems have been provided in actual use. Firstly, the pipes are simply fastened with bolts and nuts. As the conduit was formed, there was a problem that the initial conduit state could not be firmly maintained for a long time. That is, because the connection of the pipe as described above simply by using a bolt and nut, the phenomenon that the connection between the short circuit between each other due to the earth pressure when the actual use was often caused.

둘째로는 맨홀과 맨홀 사이에 정 위치된 관로와 이 관로 내에 위치된 지중 케이블이 온도 변화에 따라 신축 변화할시 이에 대한 대응책이 전혀 마련되어 있지 않아 연결 부위의 파손과 단락이 자주 초래되는 문제 현상과 더불어 지중 케이블의 단선이 자주 초래되어 선로 장애가 발생되는 문제점이 있었다.Second, there is no countermeasure when the pipeline located between the manhole and the manhole and the underground cable located in the pipeline changes and contracts according to temperature changes. In addition, there is a problem that the line failure is often caused by the disconnection of underground cables.

셋째로는 내측이 단순 관통된 형상을 취하고 있어, 내측에 배선되는 지중 케이블간의 마찰 현상이 초래되어 선로 장애를 유발시키는 문제점이 있었다.Third, since the inside has a simple through shape, friction between underground cables that are wired inside causes a problem of causing a line failure.

넷째로는 상술한 문제점들로 인해 해마다 막대한 유지 보수 비용을 책정해야 하는 매우 비경제적인 문제점이 있었다.Fourthly, due to the problems described above, there is a very uneconomic problem that requires a huge maintenance cost each year.

이런 종래의 문제점들을 해결하기 위하여, 맞닿는 방향의 외주연 사방에는 가이드홈이 각각 형성되어 있고, 내측에는 삽입설치홈이 형성되어 있으며, 특정 위치의 외주연에는 상기 삽입 설치홈과 외부를 연통하는 나사공이 등간격으로 수개 형성되어 있고, 내측에는 수개로 분할된 배선공이 형성되어 있으며, 상기 분할된 배선공이 형성된 내측 중앙에는 지지 막대를 삽입 고정할 수 있는 고정공이 형성되 어 있고, 맞닿지 않는 부위에는 암,수 연결 플랜지가 형성되어 있는 2조 한쌍의 보호관과; 접하는 보호관의 외주연에 연결 설치되어 있되, 양측 내주연에는 보호관의 가이드홈에 삽입 위치되는 걸림 돌기가 형성되어 있는 연결관과; 상기, 2조 한쌍으로 이루어진 보호관의 삽입 설치홈에 삽입 위치되어 있되, 양측 외주연에는 관통공이 등간격으로 수개 형성되어 있는 신축관을 일체로 포함하여 구성됨을 특징으로 하는 지중 케이블 보호관이 2005년 7월 20일자 특허등록 제501209호로 등록공고된바 있었다.In order to solve these conventional problems, guide grooves are formed on the outer circumferential edges of the abutting direction, respectively, and insertion grooves are formed on the inner side, and screws that communicate the outside with the insertion installation grooves on the outer circumference of a specific position. A plurality of balls are formed at equal intervals, and a plurality of divided wiring holes are formed in the inner side, and a fixing hole for inserting and fixing a supporting rod is formed in the inner center in which the divided wiring holes are formed, A pair of protective pipes having a male connecting flange formed thereon; It is connected to the outer periphery of the protective tube is in contact with, the inner periphery on both sides of the connector is formed with a locking projection is inserted into the guide groove of the protective tube; The underground cable protective tube is characterized in that it is inserted into the insertion installation groove of the pair of protective tube, the inner side of the outer periphery of the both sides of the cable comprises a plurality of through-holes are formed at equal intervals integrally formed It was registered as a patent registration No. 501209 dated May 20.

그러나, 이런 종래의 지중 케이블 보호관은 무더운 여름철에 신축관이 늘어나고 추운 겨울철 신축관이 보호관 내측에서 팽창과 수축을 반복함에 따라 여름철 팽창시 팽창분의 신축관이 보호관 내측에서 위치될 공간이 없어 한 쌍의 보호관이 서로 맞닿아 있는 선단면을 벌리면서 외부로 돌출되고, 이때 한 쌍의 보호관 외주연과 연결관의 내주연 사이를 채우면서 한 쌍의 보호관 선단면을 벌리게 되면서 결국, 한 쌍의 보호관의 이음부를 틀어지게 하여 결속을 방해함에 따라 지중 케이블을 효과적으로 보호하지 못하는 문제점이 발생되었다.However, such a conventional underground cable sheath is a pair of expansion tubes in the hot summer season and the expansion and contraction of the cold winter expansion pipe repeats the expansion and contraction inside the protective tube there is no room for the expansion tube of the expanded portion to be located inside the protective tube during summer expansion. The protective pipes of the protective pipes are projected to the outside while spreading the leading edges, and the pair of protective pipes are opened to fill the gap between the outer circumference of the pair of protective pipes and the inner circumference of the connecting pipe. There is a problem in that the underground cable is not effectively protected by twisting the joints and preventing binding.
