본 발명은 통신선, 고압선 등의 지중케이블이 지중에 매설되는 경우 지중케이블이 매설된 지역의 지반 침하에 따라 발생되는 지중케이블의 파손되는 것을 방지하도록 하는 전기 지중케이블 보호 구조물에 관한 것이다.The present invention relates to an electric underground cable protection structure to prevent the damage of the underground cable generated by the ground subsidence of the area where the underground cable is buried when the underground cable, such as communication lines, high-voltage cable is embedded in the ground.

통신선, 고압선 등과 같은 지중케이블이 지중에 매설되는 지역에는 표지에 의해 지중에 지중케이블이 지나는 지역임을 도시한다.The area where underground cables, such as communication lines and high-voltage cables, are buried in the ground, indicates that the underground cables pass through the ground by markings.

예를 들면, 통신선이 지중에 매설된 지역에는 "통신선 매설 지역"이라는 내용으로 주변에 통신선이 지중에 매설되어 있다는 표식(標識)을 나타내고, 고압선이 지중에 매설된 지역에는 "고압선 매설 지역"이라는 내용과 같이 고압선이 지중에 매설되어 있다는 표식을 나타낸다.For example, the area in which telecommunication lines are buried in the ground indicates "communication line buried area" and the mark indicating that communication lines are buried in the ground, and the area in which the high voltage line is buried is called "high voltage buried area". As shown in the figure, a mark indicates that a high-voltage cable is buried in the ground.

이는 통신선, 고압선 등의 지중케이블을 매설하고 있으므로 공사 작업을 시행하는 경우 주위를 요망(要望)하고자 함으로, 공사에 따른 지중케이블의 파손으로 공공이익을 저해(沮害)할 염려가 있기 때문이다.This is because underground cables such as telecommunication lines and high voltage cables are buried, so when the construction work is carried out, there is a possibility that the public interest may be impaired due to the damage of underground cables.

그러나, 이와 같은 지중케이블이 지중에 매설된 경우에도 연약지반에 지중케이블이 매설된 경우에는 지중선이 지반침하에 따라 외피(外皮)가 파손되는 문제점이 발생되고, 이에 따라 지중케이블 관로가 단락(短絡)되는 원인을 제공하고 있다.However, even when such underground cables are buried in the ground, when underground cables are buried in the soft ground, there is a problem that the outer cable is damaged due to the ground subsidence. It provides the cause.

본 발명은 상술한 문제점을 감안하여 안출한 것으로, 본 발명은, 통신선, 전기선 등의 지중케이블이 지중에 매설되는 경우 지반 침하에 따라 외피가 파손되는 사례를 방지할 수 있도록 보호 구조물을 지중케이블의 외측에 설치하고, 지반 침하에 따라 주름 연결관의 주름부가 늘어나 보호 구조물이 파손되지 않도록 하는 것을 그 목적으로 하는 전기 지중케이블 보호 구조물을 제공하는 것이다.The present invention has been made in view of the above-described problems, the present invention, when the underground cable, such as communication lines, electric cables are buried in the ground to protect the case of the damage to the shell due to ground subsidence of the protective structure of the underground cable It is provided on the outside, and to provide an electric underground cable protection structure for the purpose of preventing the damage to the protective structure of the corrugated connector increases as the ground subsidence.

이하, 첨부 도면을 참조하여 본 발명의 구성을 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated with reference to an accompanying drawing.
