이하, 본 발명의 일실시예에 따른 전기통신 케이블용 맨홀에 대한 작용 및 효과를 설명하도록 한다.Hereinafter, the operation and effects on the telecommunication cable manhole according to an embodiment of the present invention.

우선, 몸체부(110)는 폐합성수지가 사출에 의해 외형이 형성된다, 이때 몸체부(110)의 벽체 내부에는 진공부(120)가 형성된다.First, the body portion 110 is formed by the injection of waste synthetic resin, the vacuum portion 120 is formed inside the wall of the body portion 110.

몸체부(110)가 생활에서 쓰고 버려지는 복합비닐류인 폐합성수지를 재활용함으로써, 환경오염을 방지하고 경제적인 효과를 지닌다.By recycling the waste synthetic resin, which is a composite vinyl that the body 110 is used and thrown away from life, it prevents environmental pollution and has an economic effect.

또한, 종래의 콘크리트로 이루어지는 맨홀보다 무게를 현저히 줄여 작업이 용이하고, 종래의 플라스틱 소재로 이루어지는 맨홀보다 강성을 보강하여 내부변형으로 인한 주변지면의 침하 문제점을 해결할 수 있다.In addition, it is easier to work by significantly reducing the weight than the conventional manhole made of concrete, it is possible to solve the problem of settlement of the surrounding ground due to internal deformation by reinforcing the rigidity than the manhole made of a conventional plastic material.

그리고, 몸체부(110)는 이중벽 구조로 이루어져 내부에 진공부(120)를 형성함에 따라 외부열이 몸체부(110)의 내부공간으로 전달되는 것을 차단하여 결로, 성애 발생을 방지하게 된다.And, the body portion 110 is formed of a double-wall structure to form a vacuum portion 120 therein to prevent the external heat is transferred to the internal space of the body portion 110 to prevent condensation, sexual occurrence.

이후, 몸체부(110)의 측면에 형성된 배선홀(112)에 연결부(140)를 고정시킨다.Thereafter, the connection part 140 is fixed to the wiring hole 112 formed at the side of the body part 110.

연결부(140)의 연결은 이음관(141)을 배선홀(112)의 내측에서 외측으로 삽입한다, 그리고, 배선홀(112)을 통과하여 외측으로 돌출되는 부위에 조임구(145)가 나사결합됨으로써, 연결된다.Connection of the connecting portion 140 inserts the fitting pipe 141 from the inside of the wiring hole 112 to the outside, and the fastener 145 is screwed to the portion projecting outward through the wiring hole 112. By doing so, it is connected.

이때, 이음관(141)에는 이탈방지부재(143)인 플랜지가 형성되어 플랜지가 배 선홀(112)에 걸리게 되어 외측으로 이탈되지 않고 배선홀(112)의 외측에서 나사결합되는 조임구(145)에 의해 배선홀(112)에 고정된다.At this time, the flange 141 is formed in the fitting pipe 141 so that the flange is caught in the wiring hole 112 so that it is not detached outwards and is screwed out of the wiring hole 112. It is fixed to the wiring hole 112 by the.

또한, 배선홀(112)의 외측면과 조임구(145) 사이에는 고무패킹(150)이 구비되고, 와셔(160)가 개재되어 조임구(145)의 조임에 의해 와셔(160)가 고무패킹(150)을 몸체부(110)측으로 가압함으로써, 배선홀(112)의 연결부위가 밀폐되게 된다.In addition, a rubber packing 150 is provided between the outer surface of the wiring hole 112 and the fastener 145, and the washer 160 is interposed with the washer 160 by tightening the fastener 145. By pressing the 150 to the body portion 110 side, the connection portion of the wiring hole 112 is sealed.

상기한 상태로 지중에 매설하고 지중의 전기통신용 케이블을 이음관(141)과 조임구(145)의 관로(142,146)로 삽입하여 몸체부(110)의 내부공간에서 커넥터에 의해 접속되는 것이다.It is embedded in the ground in the above state and the underground telecommunication cable is inserted into the pipes 142 and 146 of the joint pipe 141 and the fastener 145 to be connected by the connector in the internal space of the body portion 110.

이때, 조임구(145)의 내부에는 고무링(170)이 구비되어 조임구(145)와 전기통신용 케이블 사이틈을 밀폐시킨다.At this time, the rubber ring 170 is provided inside the fastener 145 to seal the gap between the fastener 145 and the cable for telecommunication.

이처럼 배선홀(112)과 전기통신용 케이블의 연결부위를 밀폐하는 구조에 의해 몸체부(110)의 내부공간으로 침수하는 물을 차단시켜 물이 고이는 현상을 제거한다.As such, the structure in which the wiring hole 112 and the connection portion of the telecommunication cable is sealed to block the water submerged into the internal space of the body 110 removes the phenomenon of water accumulation.

이후, 몸체부(110)의 개구된 상부를 커버(130)로 덮어주고, 맨홀(100) 주위에 흙을 되 메우기하여 작업을 완료한다.Thereafter, the opened upper portion of the body 110 is covered with the cover 130, and the work is completed by filling up the soil around the manhole 100.

이때, 커버(130)와 몸체부(110)는 절곡턱(115)과 수용홈(135)의 의해 접촉면적을 넓게 함으로써, 몸체부(110)의 내부공간의 밀폐력을 향상시킨다.At this time, the cover 130 and the body portion 110 by increasing the contact area by the bending jaw 115 and the receiving groove 135, thereby improving the sealing force of the internal space of the body portion 110.

그리고, 커버(130)의 상면에는 별도의 도구가 삽입되도록 파지홈(137)이 형성되어 전기통신용 케이블 배선의 유지보수 시 개폐가 용이한 장점을 갖는다.In addition, the gripping groove 137 is formed on the upper surface of the cover 130 so that a separate tool is inserted, and thus the opening and closing is easily performed during maintenance of the telecommunication cable wiring.
