이 도면에 도시한 바와 같이 본 실시예의 공동구는, 파형(104)과 일정한 곡률을 갖는 다수의 강판(102)을 원통형을 이루도록 서로 조립연결된 파형강관(100)과, 파형강관(100)의 내측 저면에 일정한 간격을 두고 각 한쌍이 고정되어 직립된 상태를 유지하고 보조지지대(112)에 의해 간격이 일정하게 유지된 주지지대(110)와, 파형강관(100)의 상면에 일정한 간격을 두고 고정되고 주지지대(110)의 상부가 슬라이딩가능하게 삽입되는 관체(130)와, 파형강관(100)의 길이 방향을 따라 각 주지지대(110)의 측면에 수평하게 고정된 다수의 선반(120)과, 파형강관(100)의 측면에 고정되어 각 선반(120)을 지지하고 각 주지지대(110)의 하단 및 관체(130)의 상단에 양단이 각각 고정된 굴절빔(160)으로 이루어진다.As shown in the figure, the hollow sphere of the present embodiment, the corrugated steel pipe 100 and the inner bottom of the corrugated steel pipe 100 are assembled to each other to form a cylindrical shape of the corrugated 104 and a plurality of steel sheets 102 having a constant curvature It is fixed at regular intervals on the upper surface of the support zone 110 and the corrugated steel pipe 100, each pair is fixed at regular intervals to maintain the upright state and the interval is kept constant by the auxiliary support 112 and An upper part of the support 110 is slidably inserted, a plurality of shelves 120 horizontally fixed to the side of each support 110 along the longitudinal direction of the corrugated steel pipe 100, It is fixed to the side of the corrugated steel pipe 100 to support each shelf 120 and consists of a refracting beam 160, both ends of which are respectively fixed to the lower end of each support zone 110 and the upper end of the tube body 130.

각 강판(102)은 볼트(140)에 의해 서로 연결된다. 그리고 각 주지지대(110)의 저면 및 각 관체(130)의 상면에는 플레이트(114)가 각각 고정되고, 각 플레이트(114)는 볼트(140)에 의해 파형강관(100)에 고정된다. 이러한 플레이트(114)는 강판(102)의 파형(104)과 일치하는 파형이 형성되면, 결합상태가 더욱 견고하게 된다.Each steel plate 102 is connected to each other by bolts 140. And the plate 114 is fixed to the bottom of each support zone 110 and the upper surface of each tube body 130, each plate 114 is fixed to the corrugated steel pipe 100 by a bolt 140. When the plate 114 is formed to match the waveform 104 of the steel plate 102, the bonding state becomes more robust.

그리고 각 선반(120)도 볼트(140)에 의해 굴절빔(160)에 고정된다.Each shelf 120 is also fixed to the refraction beam 160 by bolts 140.

또한 각 주지지대(110)에는 파형강관(100)의 내부를 조명하기 위한 램프(180)가 설치되고, 각 램프(180)에는 전원이 공급된다.In addition, a lamp 180 for illuminating the inside of the corrugated steel pipe 100 is installed in each support zone 110, and power is supplied to each lamp 180.

한편, 각 주지지대(110)의 하단 및 파형강관(100)의 내측 바닥부에는 콘크리트(170)가 포장되어, 각 주지지대(110)의 설치를 견고하게 한다.On the other hand, the bottom of each support 110 and the inner bottom portion of the corrugated steel pipe 100, the concrete 170 is paved, so that the installation of each support 110 is firm.

이하에서는 상기와 같은 구성을 갖는 공동구의 작용을 설명한다.Hereinafter, the operation of the cavity sphere having the configuration as described above.

파형(104)이 형성되고, 일정한 곡률을 가지고 구부려진 각 강판(102)을 볼트(140)를 사용하여 원통형으로 조립한다. 그리고 각 주지지대(110)의 저면과 각 관체(130)의 상면에 플레이트(114)를 용접으로 고정하고, 각 플레이트(114)는 파형강관(100)의 저면과 상면에 각각 볼트(140)로 고정한다.A waveform 104 is formed, and each steel sheet 102 bent with a constant curvature is assembled into a cylinder using the bolt 140. Then, the plate 114 is fixed to the bottom of each support zone 110 and the upper surface of each tube body 130 by welding, and each plate 114 is bolted to the bottom and the upper surface of the corrugated steel pipe 100, respectively. Fix it.

따라서 주지지대(110)는 직립된 상태가 되며, 각 주지지대(110)의 사이에 설치되는 보조지지대(112)에 의해 주지지대(110)간의 간격이 유지된다. 그리고 주지지대(110)의 상단은 관체(130) 내에 삽입되어 있게 된다.Therefore, the support zone 110 is in an upright state, and the interval between the support zones 110 is maintained by the auxiliary support 112 installed between the respective support zones 110. And the upper end of the support zone 110 is inserted into the tube body (130).

각 주지지대(110)에 설치된 각 선반(120)에는 각종의 케이블(150)이나 배관(152)들이 설치된다. 작업자는 각 주지지대(110)의 사이로 지나다니며 케이블(150)이나 배관(152)에 대한 보수작업을 할 수 있으며, 램프(180)는 파형강관(100)내를 조명하게 된다.Each shelf 120 installed in each support zone 110 is provided with various cables 150 or pipes 152. The operator may pass between each support zone 110 and perform repair work on the cable 150 or the pipe 152, and the lamp 180 illuminates the corrugated steel pipe 100.

이러한 파형강관(100)은 파형(104)이 형성되고 원통형을 가지는 구조적인 형상 때문에 상당한 형상강도를 가지게 되므로, 파형강관(100)은 그 상부에 덮여지는 흙의 무게를 이길 수 있다.Since the corrugated steel pipe 100 has a considerable shape strength because of the structural shape in which the corrugated 104 is formed and has a cylindrical shape, the corrugated steel pipe 100 can beat the weight of soil covered thereon.

한편 파형강관(100)의 형상의 변형시, 각 주지지대(110)의 상단이 각 관체(130) 내에서 유동하고, 각 굴절빔(160)이 파형강관(100)의 측면을 지지하므로, 주지지대(110)는 그 형상에 변형이 발생하지 않게 된다.Meanwhile, when the shape of the corrugated steel pipe 100 is deformed, the upper end of each support zone 110 flows in each of the tubular bodies 130, and each of the refractive beams 160 supports the side surface of the corrugated steel pipe 100. Zone 110 is such that deformation does not occur in its shape.

만일, 파형강관(100)을 덮는 하중이 지나치게 커서 파형강관(100)이 눌려진다면, 상부의 파형강관(100)에 고정된 관체(130)가 하방의 주지지대(110)에 접촉되어 다시 2차적으로 지지된다. 따라서 파형강관(100) 내의 케이블(150)이나 배관(152)들이 안전하게 보호된다.If the load covering the corrugated steel pipe 100 is too large and the corrugated steel pipe 100 is pressed, the tubular body 130 fixed to the upper corrugated steel pipe 100 contacts the lower support zone 110 and is again secondary. Is supported. Therefore, the cable 150 or the pipe 152 in the corrugated steel pipe 100 is securely protected.

이상에서 설명한 바와 같이 본 발명은, 파형(104)을 갖는 강판(102)으로 이루어진 파형강관(100)과, 파형강관(100)의 내측 저면에서 직립된 상태로 설치된 주지지대(110)와, 파형강관(100)의 상면에 고정되고 주지지대(110)의 상부가 슬라이딩가능하게 삽입되는 관체(130)와, 파형강관(100)의 길이 방향을 따라 주지지대(110)의 측면에 수평하게 고정된 다수의 선반(120)과, 파형강관(100)의 측면에 고정되어 각 선반(120)을 지지하고 각 주지지대(110)의 하단 및 관체(130)의 상단에 양단이 각각 고정된 굴절빔(160)으로 이루어진 파형강관 공동구로서, 강판(102)을 조립함에 의해 파형강관(100)이 완성되므로 시공작업이 용이하고 시공기간이 단축되는 효과가 있다.As described above, the present invention provides a corrugated steel pipe 100 made of a steel plate 102 having a corrugated wave 104, a support base 110 installed in an upright state on an inner bottom surface of the corrugated steel pipe 100, and a corrugated wave.
