본 발명은 전기시설 옥내외 분야 등에 사용가능하되, 지중 전기 케이블 보호관 구조에 관한 것으로서, 보다 상세하게는 지중케이블을 연속적으로 둘러싸고 있어 지중케이블을 외부충격으로부터 효과적으로 보호할 수 있고, 포크레인과 같은 외부충격으로부터 위치가 이탈되지 않고 그 충격을 흡수함으로써 지중케이블을 보다 효과적으로 보호할 수 있는 지중 전기 케이블 보호관 구조에 관한 것이다.The present invention can be used in indoor and outdoor fields, such as indoors, and relates to the structure of the underground electric cable protection tube, and more particularly, the underground cable is continuously surrounded to effectively protect the underground cable from external shocks, and external shocks such as fork lanes. The present invention relates to an underground electric cable sheath structure that can more effectively protect an underground cable by absorbing its impact without deviating from its position.

종래에는 다수의 신호나 전원을 동시에 전달할 수 있도록 케이블을 설치할 수 있으며, 그 케이블은 철탑이나 전주를 통하여 설치되기는 하지만, 땅속에도 케이블이 묻히게 되어 일측 장소에서 다른 장소까지 신호나 전원을 전달할 수 있도록 하여 왔다.Conventionally, a cable may be installed to simultaneously transmit a plurality of signals or power, and the cable may be installed through a steel tower or telephone pole, but the cable may be buried in the ground so that signals or power may be transmitted from one place to another. come.

종래의 케이블이 땅속에 묻히게 되는 경우 케이블은 둥근 원형의 관 내측에 삽입되어 지중에 설치되었다. 상기와 같이 케이블이 지중에 묻힌 후에는 도로의 굴삭공사 등으로 땅이 파헤쳐지는 경우가 발생하였다. 즉, 수도관이나 가스관 및 케 이블관 등을 묻거나 보수하기 위하여 도로의 굴삭 작업을 실시하는 것이었다. 상기의 경우 작업을 신속하게 하기 위하여 포크레인 등의 중장비를 이용하게 되었다. 이때, 포크레인등의 중장비 작업자가 신중하게 작업을 실시하지 못하는 경우 가스관이나 수도관을 잘못 건드리게 되어 가스폭발 사고나 수도물이 새오나오는 사고가 종종 발생하였다. 또한, 가스관이나 수도관 이외에 지중케이블선이 내장된 관을 잘못 건드려서 파손될 때 케이블이 단선되는 경우가 발생되었다.When a conventional cable is buried in the ground, the cable is inserted into a round circular tube and installed underground. As described above, after the cable is buried in the ground, the ground is dug up by road excavation. In other words, road excavation was performed to bury or repair water pipes, gas pipes, and cable pipes. In this case, in order to speed up the work, heavy equipment such as a fork-lane was used. At this time, when heavy equipment workers such as fork lanes do not work carefully, gas or water pipes were touched incorrectly, and gas explosion accidents and leaking water were often caused. In addition, the cable is broken when the underground cable wire is broken by a mistake in touching the pipe in which the underground cable line is installed, in addition to the gas pipe or the water pipe.

상기와 같이 케이블이 단선되는 경우 단선된 케이블을 다시 연결하는 것이 단순한 작업이 아니었다. 즉, 단순한 동선과 같이 단선된 동선의 피복을 벗기고, 그 동선을 서로 연결하여 단선된 동선을 연결하는 작업과는 대단히 다른 작업이었다. 케이블의 경우에는 한 케이블 내측에 다수의 광섬유가 포함되어 있으며, 그 광섬유들을 전부 연결하는 작업도 힘들 뿐만 아니라 다수의 광섬유를 서로 연결하였다고 하더라도 그 광섬유를 일측과 타측이 서로 올바르게 연결되도록 하는 것도 대단히 어려운 작업이었다. 일측에서는 +신호를 전달하였으나, 그 신호를 전달하는 광섬유가 단선된 후에 잘못 연결되어 -신호를 전달하게 되는 경우가 발생되는 것이었다. When the cable is disconnected as described above, reconnecting the disconnected cable was not a simple task. In other words, it was very different from the work of stripping the copper wires that were disconnected like a simple copper wire and connecting the copper wires to each other. In the case of a cable, a plurality of optical fibers are included in one cable, and it is difficult to connect all the optical fibers, and even if a plurality of optical fibers are connected to each other, it is very difficult for one and the other to be correctly connected to each other. It was a job. On one side, the + signal was transmitted, but the optical fiber carrying the signal was disconnected and then incorrectly connected to transmit the-signal.

따라서, 종래에는 지중케이블이 묻히게 되는 관의 상부에 아크릴 재질로 된 단순한 판을 올려놓도록 하였다. 이 아크릴 판에 의하여 포크레인 작업을 할 때, 포크레인의 발이 아크릴 판에 걸리도록 하여 관으로 직접 포크레인의 발이 접하지 않도록 한 것이었다.Therefore, in the related art, a simple plate made of acrylic is placed on top of the tube where the underground cable is buried. When the forkrain work was carried out by this acrylic plate, the foot of the forklift was caught by the acrylic plate so that the foot of the forkrain was not directly contacted with the pipe.

그러나, 상기와 같은 종래의 아크릴 판은 낱개의 판이 지중케이블 관의 상 부에 올려지기 때문에 흙이 올려지게 될 때 아크릴 판이 기울어져서 매몰되는 경우가 종종 발생되었으며, 이와 같은 경우 아크릴 판이 정상적인 위치에서 벗어나 매몰되어 있기 때문에 중장비 등의 굴삭작업 시에 정상적으로 지중케이블의 관을 보호해 줄 수가 없게 되었다. However, in the conventional acrylic plate as described above, since the individual plates are placed on the upper portion of the underground cable tube, when the soil is raised, the acrylic plate is often inclined and buried. In such a case, the acrylic plate is moved out of its normal position. Because of the investment, the underground cable can not be protected normally during excavation work such as heavy equipment.

또한, 상기의 아크릴 판은 평평한 판이었기 때문에 아크릴 판이 매설되는 도중이나 매설된 후에 아크릴 판이 미끄러지기 쉽게 되는 문제점이 있었다.In addition, since the acrylic plate was a flat plate, there was a problem in that the acrylic plate easily slipped during or after the acrylic plate was embedded.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 지중케이블을 연속적으로 둘러싸고 있어 지중케이블을 외부충격으로부터 효과적으로 보호할 수 있고, 포크레인과 같은 외부충격으로부터 위치가 이탈되지 않고 그 충격을 흡수함으로써 지중케이블을 보다 효과적으로 보호할 수 있는 지중 전기 케이블 보호관 구조를 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, and surrounds the underground cable continuously can effectively protect the underground cable from the external shock, the underground cable by absorbing the impact of the location without departing from the external shock such as fork lane It is an object of the present invention to provide an underground electric cable sheath structure that can protect the more effectively.
