Abstract

A protection tube for a subterranean cable is provided to absorb external impact by forming a lower inner circumference of the subterranean cable with a semicircular rubber tube. A protection tube for a subterranean cable includes a semicircular cover tube(10), a semicircular support tube(20), an elastic cable protection tube(30), and left and right end supports(40a). The semicircular cover tube wraps and protects an upper part, a left part, and a right part of the subterranean cable. The semicircular support tube is closely adhered to a lower part of the semicircular cover tube and forms a circle. The elastic cable protection tube wraps and protects the subterranean cable while extending and fixing the semicircular support tube in a longitudinal direction. The left and right end supports wrap and protect right and left lower parts of the semicircular support tube.

Description

지중 케이블 보호관{Protection tube for subterranean cable}Protection tube for subterranean cable

본 발명은 지중 케이블 보호관에 관한 것으로서, 보다 상세하게는 하부가 개방된 ∩형상의 덮개반원관 하부에 반원형상의 받침관을 체결고정시킴으로써 지중 케이블을 보호하는 보호관의 강도를 보강하고, 지중 케이블의 하부 내주연을 고무반원관으로 형성하여 외부충격을 흡수 보호하며, 좌우측 하부에 완충부재를 구비하여 굴착기의 버킷에 의해 직접 타격받아 손상되는 것을 방지함으로써 내부의 지중 케이블을 보호하는 지중 케이블 보호관에 관한 것이다. The present invention relates to an underground cable protective tube, and more particularly, by tightening and fixing a semi-circular base tube to the lower part of the 덮개 -shaped semicircular tube with an open lower portion, to reinforce the strength of the protective tube to protect the underground cable, The inner periphery is formed of a rubber semi-circular tube to absorb and protect external shocks, and has a shock absorbing member on the lower left and right sides to prevent damage from being directly hit by the bucket of the excavator, thereby protecting the underground underground cable. .

일반적으로 주택, 상업 및, 공업단지의 지중에는 지중선로로서, 송배전 전선이 수용된 전선관, 가스배관, 상하수도관 등이 매설되어 있다. 이런 지중선로를 지중에 매설하는 이유는 안전성 및 단열성 때문이며, 지중에 장시간 동안 매설된 지중선로는 자체 노후에 의한 파손 및 침투수에 의해 부식되어 일정 시간이 지나면 보수하여야 한다. 또한, 이런 노후 및 부식 등의 원인 외에도 증설 등의 이유에서 보수하는 경우도 있다.In general, underground lines in housing, commercial and industrial complexes are embedded with conduits, gas pipes, water and sewage pipes, etc., in which transmission and distribution wires are housed. The underground line is buried under ground due to safety and thermal insulation. The underground line embedded in the ground for a long time should be repaired after a certain period of time due to corrosion due to breakage and infiltration water caused by its own aging. In addition, in addition to the causes such as aging and corrosion, such repairs may be performed for reasons such as expansion.

이와 같이, 지중선로를 보수 및 교체하기 위해서는 지중선로가 매설된 지면을 굴착하여 지중선로가 외부로 노출되도록 한 후에 보수 및 교체작업을 수행한다.As such, in order to repair and replace the underground line, the underground line is excavated and the ground line is exposed to the outside, and then the repair and replacement work is performed.

일반적인 굴착작업은 굴착기를 이용하여 빠르고 쉽게 수행하는데, 굴착기에 설치된 버킷으로 지면을 굴착한다. The general excavation work is quick and easy by using an excavator, and the ground is excavated by the bucket installed in the excavator.

이와 같이, 굴착작업이 수행되는 과정에서 굴착기의 운전자는 지중에 매설된 지중선로를 볼 수 없기 때문에 운전자의 감각으로 굴착작업을 수행한다. 운전자는 버킷이 지중선로에 닿는 충격을 감지하면 버킷을 이동시켜 버킷이 지중선로에 닿지 않도록 한 상태에서 굴착작업을 진행한다.As such, in the course of the excavation work, the driver of the excavator does not see the underground line buried in the ground, so the excavation work is performed with the driver's sense. When the driver senses the impact of the bucket on the underground track, the driver moves the bucket so that the bucket does not touch the underground track and proceeds with excavation.

그러나, 운전자가 지중선로의 위치를 알지 못한 상태에서 굴착작업을 수행하다 보면 굴착기의 버킷이 과도하게 지중선로를 가압하여 지중선로를 파괴시키는 경우가 종종 발생하며, 또한 운전자는 지중선로의 매설위치를 알지 못하기 때문에 지중선로를 따라 정확한 굴착위치를 설정하기 어려워 수시로 굴착진행방향을 수정하면서 굴착작업을 수행하여야 한다는 문제점이 있다.However, when the driver performs the excavation work without knowing the location of the underground line, the excavator bucket often presses the underground line excessively and destroys the underground line. Since it is difficult to know the exact excavation position along the underground line, there is a problem that the excavation work must be performed while modifying the excavation progress direction from time to time.

종래의 지중선로를 보호하기 위한 보호판이 설치되는 경우가 있으나, 이러한 보호판은 단지 지중선로 위에 놓여져 지중선로 버켓이 직접 닿는 것을 방지하고 있다. 하지만 이러한 보호판은 버킷이 보호판 바로 위의 흙을 파내더라도 보호판의 존재 유무를 알지 못해 버킷이 보호판과 같이 지중선로를 파손하게 되는 문제점이 있었다.In some cases, a protective plate for protecting a conventional underground line is provided, but such a protective plate is placed only on the underground line to prevent the underground line bucket from directly touching. However, such a protective plate has a problem that even if the bucket digs the soil just above the protective plate does not know the existence of the protective plate, the bucket breaks the underground line like the protective plate.

이렇게 굴착기의 버킷이 보호판을 파손시키면 보호판 전체를 버리고 다른 보호판을 공사가 끝난 후 설치하여야 하므로 자원의 낭비가 심하게 되는 문제점이 있었다.Thus, when the bucket of the excavator breaks the protection plate, the entire protection plate should be discarded and other protection plates have to be installed after construction.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 하부가 개방된 ∩형상의 덮개반원관 하부에 반원형상의 받침관을 체결고정시킴으로써 지중 케이블을 보호하는 보호관의 강도를 보강하고, 지중 케이블의 하부 내주연을 고무반원관으로 형성하여 외부충격을 흡수 보호하며, 좌우측 하부에 완충부재를 구비하여 굴착기의 버킷에 의해 직접 타격받아 손상되는 것을 방지함으로써 내부의 지중 케이블을 보호하는 지중 케이블 보호관을 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, by tightening the semi-circular base tube to the bottom of the open semi-shaped semi-circular tube of the lower part to reinforce the strength of the protective tube to protect the underground cable, and in the lower part of the underground cable It is formed with a rubber semi-circular tube to absorb and protect external shocks, and it has a buffer member on the lower left and right sides to prevent underground damage by being directly hit by the bucket of the excavator.
