본 발명은 지중 케이블 보호시설구조에 관한 것으로서, 보다 상세하게는 불 규칙한 지반에서도 지중 케이블에 비틀림이나 휨이 발생하는 것을 방지할 수 있는 지중 케이블 보호시설구조에 관한 것이다.The present invention relates to an underground cable protection facility structure, and more particularly, to an underground cable protection facility structure that can prevent twisting or bending of underground cables even in irregular soils.

일반적으로 우리나라의 가공배전선지중화는 1973년 효자동에서 광화문구간까지 복잡하게 시설되어 있는 배전선을 전선정비측면에서 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 the distribution lines, which were intricately installed from Hyoja-dong to Gwanghwamun, by relocating Jeonju along the main road to the back alley from the side 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.For reference, underground construction works can be divided into direct sales, pipelines, and electricity.

이중, 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.In the double pipe system, pipes are constructed using pipes such as synthetic resin pipes, fume pipes, and fume pipes, and then cables are laid.

이러한, 관로식 공사에 사용되는 관로는 상술한 바와 같이 합성수지관, 강관, 흄관 등과 같은 관재(pipes)가 주로 이용되었는데 이러한 관재는 지금까지 매우 단순한 형태로 제작되어 있어 실사용시 여러 가지의 문제점을 제공하였다.As the pipe used in the pipeline construction, pipes such as synthetic resin pipes, steel pipes, and fume pipes were mainly used as described above, and these pipes have been manufactured in a very simple form so that various problems can be provided in actual use. It was.

특히, 지중 케이블이 설치되는 지반이 연약지반인 경우 불규칙한 지반에 케이블이 구브러지거나 심지어 파손되고, 이를 보수하기 위하여 막대한 유지 보수 비용이 발생하는 문제점이 있다.In particular, when the ground on which the underground cable is installed is a soft ground, the cable is bent or even broken on irregular ground, and there is a problem that a huge maintenance cost is generated to repair it.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 불규칙한 지반에서도 지중 케이블에 비틀림이나 휨이 발생하는 것을 방지할 수 있는 지중 케이블 보 호시설구조를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide an underground cable protection facility structure that can prevent the occurrence of twisting or bending of the underground cable even in irregular ground.

도 1 내지 도 2를 참조하면, 본 발명에 따른 지중 케이블 보호시설구조(100)는, 지중 케이블(110)과, 본체(120)와, 실리콘(130)과, 보호커버(140)와, 몰탈(150)과, 토목섬유 보호매트(160)로 구성된다.1 to 2, the underground cable protection facility structure 100 according to the present invention, underground cable 110, the main body 120, the silicon 130, the protective cover 140, mortar 150 and a geotextile protection mat 160.

먼저, 지중 케이블(110)은 일반적인 케이블로서 심선에 커버가 형성된 형태이다.First, the underground cable 110 is a general cable is a form in which the cover is formed on the core wire.

그리고, 본체(120)는 폴리에틸렌과 같이 변형 가능한 재질로 지중 케이블(110)이 내부에 수납되도록 상단이 길이 방향으로 절개된 원통 형태로 형성되고, 외측면에 일정 간격으로 지지대(121)가 형성된다. 여기에서, 본체(120)는 지중 케이블(110)의 수납이 용이하도록 최초 벌어진 형태를 유지하다가 외압에 의해 원형을 이루도록 하는 것이 바람직하다. 여기에서 또한, 지지대(121)는 수레바퀴 형상으로 형성된다.In addition, the main body 120 is formed of a cylindrical shape in which the upper end is cut in the longitudinal direction so that the underground cable 110 is accommodated therein in a deformable material such as polyethylene, and the support 121 is formed at a predetermined interval on the outer surface. . Here, it is preferable that the main body 120 maintains the first open shape to facilitate the storage of the underground cable 110 to form a circle by external pressure. Here, the support 121 is formed in a wheel-wheel shape.

또한, 실리콘(130)은 지중 케이블(110)이 수분이나 외부 충격에 보호될 수 있도록 지중 케이블(110)과 본체(120) 사이에 충진된다.In addition, the silicon 130 is filled between the underground cable 110 and the main body 120 so that the underground cable 110 can be protected from moisture or external impact.

또, 보호커버(140)는 폴리에틸렌과 같이 변형 가능한 재질로 본체(120)가 내부에 수납되도록 상단이 길이 방향으로 절개된 원통 형태로 형성되되, 절개면 양측에 잠금 볼트홀(143)이 형성된 체결판(141)이 각각 구비되고, 측면에 일정 간격으로 몰탈 주입홀(145)이 형성된다. 여기에서, 보호커버(140)는 지중 케이블(110)의 수납이 용이하도록 최초 벌어진 형태를 유지하다가 볼트(147) 체결에 의해 원형을 이루도록 하는 것이 바람직하다. In addition, the protective cover 140 is formed of a deformable material such as polyethylene is formed in a cylindrical shape in which the upper end is cut in the longitudinal direction so that the main body 120 is stored therein, the locking bolt hole 143 is formed on both sides of the cut surface Plates 141 are provided, respectively, and mortar injection holes 145 are formed at predetermined intervals. Here, the protective cover 140 is preferably maintained to form a circular shape by fastening the bolt 147 while maintaining the first open form to facilitate the storage of the underground cable 110.

한편, 몰탈(150)은 보호커버(140)의 몰탈 주입홀(145)을 통해 주입되어 본체(120)와 보호커버(140) 사이에 충진된다.On the other hand, the mortar 150 is injected through the mortar injection hole 145 of the protective cover 140 is filled between the main body 120 and the protective cover 140.

그리고, 토목섬유 보호매트(160)는 외부 충격으로부터 보호커버(140)를 보호하도록 보호커버(140)가 설치된 후 되메우기된 지면에 설치된다.The geotextile protection mat 160 is installed on the backfilled surface after the protective cover 140 is installed to protect the protective cover 140 from external impact.

이하, 본 발명에 따른 지중 케이블 보호시설구조의 설치 과정 및 작용을 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, the installation process and operation of the underground cable protective facility structure according to the present invention will be described in detail with reference to the accompanying drawings.

먼저, 지중에 상단이 넓고 하단이 좁게 2단으로 터파기를 수행한다.First of all, in the underground, the top is wide and the bottom is narrow.

그리고, 하단 터파기 공간(101)에 보호커버(140)를 설치하고, 보호커버(140) 내부에 본체(120)를 수납한다. 그러면, 본체(120)는 지지대(121)에 의해 보호커버(140)와 일정 거리 이격되어 몰탈(150)이 채워질 수 있는 공간을 형성한다.In addition, the protective cover 140 is installed in the lower trench structure 101, and the main body 120 is accommodated in the protective cover 140. Then, the main body 120 is spaced a predetermined distance from the protective cover 140 by the support 121 to form a space in which the mortar 150 can be filled.

그런 다음, 본체(120) 내부에 지중 케이블(110)을 수납하고, 보호커버(140)의 체결판(141)에 형성된 잠금 볼트홀(143)에 볼트(147)를 체결하면 보호커버(140) 및 본체(120)의 형상이 원형으로 변형된다.Then, the underground cable 110 is accommodated in the main body 120, and when the bolt 147 is fastened to the lock bolt hole 143 formed in the fastening plate 141 of the protective cover 140, the protective cover 140 is provided. And the shape of the main body 120 is deformed into a circle.

이러한 상태에서, 지중 케이블(110)과 본체(120) 사이의 공간에 실리콘(130)을 충진하고, 보호커버(140)의 몰탈 주입홀(145)을 통해 몰탈(150)을 주입한다.In this state, the silicon 130 is filled in the space between the underground cable 110 and the main body 120, and the mortar 150 is injected through the mortar injection hole 145 of the protective cover 140.

몰탈(150)의 주입이 완료되면 하단 터파기 공간(101)을 되메우기하고, 되메우기된 상면에 토목섬유 보호매트(160)를 설치하고, 상단 터파기 공간(103)을 되메우기하여 설치를 완료한다.When the injection of the mortar 150 is completed, the bottom trench space 101 is backfilled, the geotextile protection mat 160 is installed on the top surface which is backfilled, and the top trench space 103 is completed to complete the installation.

따라서, 지중 케이블을 본체와 보호 커버 내부에 수납하고, 실리콘과 몰탈을 충진하며, 2단으로 터파기된 지반 내부에 설치하고, 상단에 토목섬유 보호매트를 설치함으로써 충격이나 지반 침하와 같은 외압에 의해 지중 케이블이 비틀리거나 휘는 것을 막을 수 있다.Therefore, the underground cable is stored inside the main body and the protective cover, filled with silicon and mortar, and installed inside the two-burst ground, and the geotextile protection mat is installed at the top to protect against external pressure such as impact or ground subsidence. This prevents underground cables from twisting or bending.

상기와 같이 구성되는 본 발명인 지중 케이블 보호시설구조에 따르면, 불규칙한 지반에서도 지중 케이블에 비틀림이나 휨이 발생하는 것을 방지할 수 있는 다.According to the underground cable protective facility structure of the present invention configured as described above, it is possible to prevent the occurrence of torsion or warp in the underground cable even in irregular ground.

본 발명은 다양하게 변형될 수 있고 여러 가지 형태를 취할 수 있으며 상기 발명의 상세한 설명에서는 그에 따른 특별한 실시 예에 대해서만 기술하였다. 하지만 본 발명은 상세한 설명에서 언급되는 특별한 형태로 한정되는 것이 아닌 것으로 이해되어야 하며, 오히려 첨부된 청구범위에 의해 정의되는 본 발명의 정신과 범위 내에 있는 모든 변형물과 균등물 및 대체물을 포함하는 것으로 이해되어야 한다.As those skilled in the art would realize, the described embodiments may be modified in various ways, all without departing from the spirit or scope of the present invention. It is to be understood, however, that the present invention is not limited to the specific forms referred to in the description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. Should be.
