본 발명은 건축단지내 지중전기 케이블 보호관 구조에 관한 것으로서, 보다 상세하게는 지중케이블을 사방에서 감싸고 또한 상부에는 반호형상의 보호부재를 설치함으로써 지중케이블이 매설된 주변을 포크레인을 이용하여 굴착하는 과정에서 작업자가 지중에 매설된 지중케이블의 위치를 파악하지 못해 지중케이블을 파괴하거나 손상시키는 것을 사전에 방지할 수 있는 건축단지내 지중전기 케이블 보호관 구조에 관한 것이다.The present invention relates to the structure of the underground electric cable protection tube in the building complex, and more particularly, in the process of digging around the underground cable by using a fork crane by installing a semi-circular arc-shaped protection member on the four sides of the underground cable. The present invention relates to the construction of underground electric cable protection pipes in a building complex that prevents the worker from knowing the location of underground cables buried in the ground and thus preventing or destroying the underground cables.

일반적으로 주택, 상업 및 공업단지의 지중에는 송,배전을 위한 지중케이블이 매설되고 있다.In general, underground cables for transmission and distribution are buried in residential, commercial and industrial complexes.

이처럼 지중케이블이 지중에 매설되는 이유는 안전성 및 단열성 때문이며, 지중에 장시간 동안 매설된 지중케이블은 자체 노후에 의한 파손 및 침투수에 의해 부식되어 일정 시간이 지나면 보수하여야 한다.The underground cable is buried in the ground because of its safety and thermal insulation. The underground cable buried in the ground for a long time should be repaired after a certain time due to corrosion due to breakage and infiltration water caused by its own aging.

또한, 이런 노후 및 부식 등의 원인 외에도 증설 등의 이유에서 보수하는 경우도 있다.In addition, in addition to the causes such as aging and corrosion, such repairs may be performed for reasons such as expansion.

이와 같이, 지중케이블을 보수 및 교체하기 위해서는 지중케이블이 매설된 지면을 굴착하여 지중케이블이 외부로 노출되도록 한 후에 보수 및 교체작업을 수 행한다.As described above, in order to repair and replace the underground cable, the ground cable is excavated to allow the underground cable to be exposed to the outside, and then the maintenance and replacement work is performed.

일반적인 굴착작업은 포크레인을 이용하여 빠르고 쉽게 수행하는데, 백호우에 설치된 버킷을 이용하여 지면을 굴착한다. 하지만 포크레인을 이용한 굴착작업시 운전자는 지중에 매설된 지중케이블을 볼 수 없기 때문에 운전자의 감각에 의존하면서 지하 굴착작업을 수행하였다.The general excavation work is quick and easy by using a fork lane, and the ground is excavated by using a bucket installed in the backhoe. However, in the excavation work using the fork-lane, the driver could not see the underground cable buried in the ground, so he performed underground excavation work depending on the driver's sense.

따라서 운전자는 버킷이 지중케이블에 닿는 충격을 감지하면 버킷을 이동시켜 버킷이 지중케이블에 닿지 않도록 한 상태에서 굴착작업을 진행한다.Therefore, when the driver detects the impact that the bucket touches the underground cable, the driver moves the bucket so that the bucket does not touch the underground cable.

그러나, 운전자가 지중케이블의 위치를 알지 못한 상태에서 굴착작업을 수행하다 보면 포크레인의 버킷이 과도하게 지중케이블을 가압하여 지중케이블을 파괴시키는 경우가 종종 발생하는 문제점이 있었다.However, when the driver performs the excavation work without knowing the location of the underground cable, there is a problem that the bucket of the fork lane excessively presses the underground cable to destroy the underground cable.

또한 운전자는 지중케이블의 매설위치를 알지 못하기 때문에 지중케이블을 따라 정확한 굴착위치를 설정하기 어려워 조심스럽게 굴착진행방향을 수정하면서 굴착작업을 수행하여야 하는 문제점이 있었다.In addition, since the driver does not know the underground cable buried position, it is difficult to set the exact excavation position along the underground cable, and thus, there is a problem in that the excavation work has to be performed carefully while correcting the excavation progress direction.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 지중케이블을 사방에서 감싸고 또한 상부에는 반호형상의 보호부재를 설치함으로써 지중케이블이 매설된 주변을 포크레인을 이용하여 굴착하는 과정에서 작업자가 지중에 매설된 지중케이블의 위치를 파악하지 못해 지중케이블을 파괴하거나 손상시키는 것을 사전에 방지할 수 있는 건축단지내 지중전기 케이블 보호관 구조를 제공함에 그 목적이 있다.The present invention is to solve the above problems, the worker is embedded in the ground in the process of digging around the underground cable by using a fork lane by wrapping the underground cable in all directions and installing a semi-circular arc-shaped protection member on the top The purpose of the present invention is to provide an underground cable protection tube structure in a building complex that can prevent the underground cable from being destroyed or damaged due to the failure of the location of the underground cable.

Fastening protrusions 24 and fastening recesses 24a corresponding to the longitudinal direction are formed on the front and rear sides, respectively.

상기 보호지지판(30)은 상기 외측보호틀(20)의 외면에 대응되어 감싸는 판체로, 상기 외측보호틀(20)의 상부 중앙을 감싸는 중앙판부(32)가 형성되고, 상기 중앙판부(32)사이에 이격된 절개부(33)를 갖고 상기 중앙판부(32)를 제외한 다른 외측보호틀(20)의 좌우측 및 하부 외면을 감싸는 몸체판부(21)가 형성되어 상기 외측보호틀(20)의 길이방향 연결부를 감싸 보호한다. The protective support plate 30 is a plate body that corresponds to the outer surface of the outer protective frame 20, the central plate portion 32 surrounding the upper center of the outer protective frame 20 is formed, the central plate portion 32 The length of the outer protective frame 20 is formed by having a cutout portion 33 spaced apart therebetween and surrounding the left and right and lower outer surfaces of the outer protective frame 20 except for the central plate portion 32. Wrap directional connections to protect them.

상기 충격보호틀(40)은 정면이 반호형상인 반호몸체(41)가 형성되고, 반호몸체(41)의 내면 좌우측에는 하부로 돌출되어 상기 보호지지판(30)의 몸체판부(31)와 중앙판부(32) 사이의 절개부(33)를 통해 상기 보호지지판(30)과 상기 외측보호틀(20) 사이에 걸림고정되는 걸림고정턱부(42,42a)가 각각 형성되어 외부충격을 견뎌내어 상기 지중케이블(50)을 보호한다.

Locking jaw portions 42 and 42a are formed between the protective support plate 30 and the outer protective frame 20 through cutouts 33 between the 32 to withstand external shocks. Protect cable 50.

이와 같은 본 발명은, 지면으로부터 포크레인의 버킷 충격시 상부에 위치된 충격보호틀(40)의 반호몸체(41)와 충돌하면서 작업자로 하여금 지면에 지중케이블(50)이 배관된 장소임을 인식시키게 되고, 이에 충격보호틀(40)에 가해진 충겨량으로 인해 반호몸체(41)는 변형되면서 충격량을 감소시키게 된다.The present invention as described above, while colliding with the half body body 41 of the impact protection frame 40 located at the top during the impact of the bucket of the fork crane from the ground and makes the operator recognize that the ground cable 50 is piped on the ground In this case, due to the amount of filling applied to the impact protection frame 40, the half body body 41 is deformed to reduce the impact amount.

이렇게 저감된 충격량은 걸림고정턱(42,42a)르 통해서 외측보호틀(20)에 전달되면서 외측보호틀(20)을 유동시키게 되며, 이때 지면과의 말찰에 의해 대부분의 충격량은 감소, 흡수된다.The impact amount thus reduced is transmitted to the outer protection frame 20 through the locking fixing jaws 42 and 42a to flow the outer protection frame 20. At this time, most of the impact amount is reduced and absorbed by friction with the ground. .

이런 상태에서도 소멸되지 않은 충격량은 외측보호틀(20) 내측의 내측탄성관(10)을 통해서 지중케이블(50)로 전달되려하나, 연질의 고무재질인 내측탄성관(10)은 차체 탄성력과 내주연의 요철부(11,12)의 떨림에 의해서 나머지 충격량을 모두 흡수, 소멸시킴으로써 외부충격으로부터 지중케이블(50)을 보다 효과적으로 다단으로 보호하게 된다.Even in this state, the impact amount that is not extinguished is to be transmitted to the underground cable 50 through the inner elastic tube 10 inside the outer protective frame 20, but the inner elastic tube 10, which is a soft rubber material, has a body elastic force and an inner portion. By vibrating the periphery of the uneven portions 11 and 12, all the remaining impact amount is absorbed and extinguished, thereby effectively protecting the underground cable 50 from external impacts in multiple stages.

이와 같이, 본 발명은 지중케이블을 사방에서 감싸고 또한 상부에는 반호형상의 보호부재를 설치함으로써 지중케이블이 매설된 주변을 포크레인을 이용하여 굴착하는 과정에서 작업자가 지중에 매설된 지중케이블의 위치를 파악하지 못해 지중케이블을 파괴하거나 손상시키는 것을 사전에 방지할 수 있는 효과가 있다.As described above, the present invention wraps the underground cable in all directions and installs a semi-arc shaped protection member on the upper part to grasp the position of the underground cable buried in the ground by the worker during the excavation process using the fork lane. Failure to do so has the effect of preventing underground cables from being destroyed or damaged.
