지중배전용 파형관 삽입형 튜브 방수 구조체{Tube waterproof structure that can be inserted into the underground distribution spirally corrugated tube}Tube waterproof structure that can be inserted into the underground distribution spirally corrugated tube}

본 발명은 지중배전용 파형관 삽입형 튜브 방수 구조체에 관한 것으로서, 보다 상세하게는 공기가 주입되고 다수개의 내측모헤어돌기로 케이블과 밀착지지되는 케이블삽입패킹튜브와 공기주입관을 통해 공기가 주입되고 내주연은 다수개의 모헤어내측링돌기를 갖는 내측팽창변형부가 케이블삽입패킹튜브와 밀착지지되며 외주연은 다수개의 모헤어외측링돌기를 갖는 외측팽창변형부가 파형관 내주연과 밀착지지되는 공기팽창튜브를 구비하여 지중 배전선로의 구조물(예를 들어, 맨홀, 핸들홀, 지상기기 기초대, 전력구 등)에 매설된 파형관 내에 케이블측으로 물이나 습기의 침투를 구조적으로 최대한 방지할 수 있어 기기보호와 수명연장 및 안전사고 등을 효과적으로 예방할 수 있는 지중배전용 파형관 삽입형 튜브 방수 구조체에 관한 것이다. The present invention relates to a corrugated tube insertion type waterproof structure for underground distribution, and more particularly, air is injected and air is injected through the cable insertion packing tube and the air injection tube, which are closely supported with the cable by a plurality of inner mohair projections, and the inner periphery The inner expansion deformable portion having a plurality of mohair inner ring projections is closely supported with the cable insertion packing tube, and the outer periphery is provided with an air expansion tube in which the outer expansion deformation portion having a plurality of mohair outer ring projections is closely supported with the inner periphery of the corrugated tube. It is possible to structurally prevent the penetration of water or moisture to the cable side in the corrugated pipe buried in the structure of the distribution line (for example, manhole, handle hole, ground equipment base, electric power bulb, etc.) It relates to a corrugated pipe-inserted tube waterproofing structure for underground distribution that can effectively prevent accidents and the like.

일반적으로 배전선로의 지상기기(예를 들어 지상 개폐기, 지상 변압기)에는 지하 케이블 다발을 보호하는 지하 배전용 파형관이 연결되어 있는바, 도 5에 도시된 바와 같이, 지하 배전용 파형관(101)의 동심적 내부에는 여러 가닥의 지하 케이블(104)들이 삽입되어 있다.In general, a corrugated pipe for underground distribution that protects an underground cable bundle is connected to a ground device (eg, a ground switch, a ground transformer) of a distribution line. As shown in FIG. 5, the Several strands of underground cables 104 are inserted in the concentric interior.

한편 우천시 등에 지상기기의 기초대 내부로 물이 유입되면, 지하 배전용 파형관(101)을 통하여 기기로 침투되는데, 이 유입된 물의 수분과 습기가 지상기기를 부식시키거나 수명을 단축하게 되고 폭우시 많은 물이 유입되는 경우 고장 및 대형정전사고, 또는 누전으로 기기 주변의 통행인에게도 안전사고의 우려가 컸었다.On the other hand, when water flows into the base of the ground equipment during rain, etc., it penetrates into the equipment through the corrugated pipe 101 for underground distribution. If a lot of water flows in, there is a high risk of safety accidents for passers-by around the equipment due to breakdowns, large-scale blackouts, or short circuits.

이런 문제점을 해결하기 위하여, "파형관(1) 내부에 동심적으로 끼워지는 동일 파형을 가진 고무링(2)과, 이 고무링(2)의 중간에 배치되는 수팽창제(3) 및 상기 고무링(2)의 내부에 동심적으로 끼위지면서 케이블(4)들을 보유 지지하는 케이블 삽입패킹(5)으로 이루어지고, 상기 고무링(2)는 원주둘레 중간에 설치된 힌지축(6)을 기준으로 반원호형으로 벌어지도록 이루어지며, 상기 고무링(2)의 상, 하단에는 조임판(7)과 받침판(8)이 보울트(9)와 너트(10)로 체결되어 이루어진 것을 특징으로 하는 지중배전용 파형관 삽입형 방수 구조체."가 실용등록 제20-0405984호(2006.01.11. 공고)가 개시된바 있었다.In order to solve this problem, "a rubber ring 2 having the same corrugation fitted concentrically inside the corrugated tube 1, a water expander 3 disposed in the middle of the rubber ring 2, and the rubber ring (2) is made of a cable insertion packing (5) that holds the cables (4) while being concentrically sandwiched inside of (2), and the rubber ring (2) is a semicircle based on the hinge shaft (6) installed in the middle of the circumference Corrugated pipe for underground distribution, characterized in that it opens in an arc shape, and at the upper and lower ends of the rubber ring (2), a tightening plate (7) and a support plate (8) are fastened with a bolt (9) and a nut (10) Inserted waterproof structure." Utility Registration No. 20-0405984 (2006.01.11. Announcement) has been disclosed.

그러나 이런 종래의 방수 구조체는, 파형관(1) 내부에 끼워지는 고무재의 고무링(2)과 수팽창제(3) 및 케이블삽입패킹(5)에 의해 파형관(1) 내부의 케이블(4)로 물이나 습기가 침투하는 것을 방지하려 하였으나, 외부충격에 의해 고무링(2)과 수팽창제(3)에 변형이 발생되면 너무나 손쉽게 케이블(4)로 물이나 습기가 손쉽게 침투되는 구조적인 문제점이 있었다.However, in this conventional waterproof structure, water into the cable (4) inside the corrugated pipe (1) by the rubber ring (2) of rubber material fitted inside the corrugated pipe (1), the water expander (3), and the cable insertion packing (5) However, there was a structural problem in that water or moisture easily penetrated into the cable 4 too easily when deformation occurred in the rubber ring 2 and the water expander 3 due to an external impact.
