Fastening and loosening operation of the tightening bolts 32 by screwing the tightening bolts 32 fixedly installed on the upper surface of the tightening holes 30 to the fastening protrusions 22 formed in the diagonal direction of the closing plate 20. Diameter and length of the pipe connection hole formed in the wall (1) of the manhole to the diameter of the connecting member 10 coupled to the insertion portion 33 of the end through The ever adjusted to the diameter of the conventional ground transmission and distribution lines to be inserted into the member 10.

즉, 맨홀의 벽체(1)에 형성되는 관로연결공의 직경이 관로연결공에 삽입되는 연결부재(10)의 직경보다 큰 경우 및 관로연결공에 삽입된 연결부재(10)에 삽입되는 통상의 지중 송배전선로의 직경이 커 관로연결을 위하여 연결부위의 직경을 조절하고자 하는 경우에는 조임구(30)의 상부면에 고정되어 마감판(20) 모서리의 체결돌기(22)의 볼트공(23)에 삽입되는 조임볼트(32)를 마감하기 위하여 조임볼트(32)에 결합된 너트(32')를 조임방향으로 조이게 되면, 너트(32')의 조임작동에 의해 조임구(30)가 마감판(20)의 연결공(21)에서 외측으로 벌어지면서 조임구(30)의 삽입부(33)와 결합된 연결부재(10)의 양단부가 관로연결공과 밀착되게 되므로서, 연결부분의 직경이 커지게 됨과 동시에 연결부재(10)의 외주면이 관로연결공에 긴밀히 밀착되게 되어 방수효과를 얻을 수 있게 되는 것이다.That is, when the diameter of the pipe connection hole formed in the wall (1) of the manhole is larger than the diameter of the connection member 10 is inserted into the pipe connection hole and inserted into the connection member 10 inserted in the pipe connection hole If the diameter of the underground transmission and distribution line is to be adjusted to adjust the diameter of the connection portion for the pipe connection, it is fixed to the upper surface of the tightening hole 30 is bolt hole 23 of the fastening protrusion 22 of the corner of the closing plate 20 When the nut 32 'coupled to the tightening bolt 32 is tightened in the tightening direction to close the tightening bolt 32 inserted into the tightening bolt 32, the tightening hole 30 is closed by the tightening operation of the nut 32'. Both ends of the connecting member 10 coupled with the insertion part 33 of the tightening hole 30 are brought into close contact with the conduit connecting hole while opening outward from the connecting hole 21 of the 20, so that the diameter of the connecting part is large. At the same time, the outer circumferential surface of the connecting member 10 is closely adhered to the pipe connection hole, thereby obtaining a waterproof effect. Will be.

그리고, 본 발명은 첨부된 도면 및 구체적인 실시 예와 관련하여 설명하였지만, 본 발명은 이에 의하여 특별히 제한되는 것은 아니며 본 발명의 기술적 사상의 범위 내에서 당해 분야의 당업자에 의하여 다양한 변형이 이루어질 수 있다.In addition, although the present invention has been described with reference to the accompanying drawings and specific embodiments, the present invention is not particularly limited thereto and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention.

이상에서와 같이 본 발명은 관로구의 양단부에 조임볼트를 통해 관로구의 직 경을 조절할 수 있는 조임구를 설치하므로서, 다양한 직경 및 두께로 이루어지는 맨홀의 관로연결공 및 지중 송배전선로와의 연결 설치를 신속 용이하고도 견고하게 이룰 수 있게 된다. 따라서, 연결 설치되는 지중 송배전선로의 상태 변화에 적절히 대응을 취해 지중 송배전선로의 파손을 미연에 방지할 수 있는 효과가 있다.As described above, the present invention provides a fastening port for adjusting the diameter of the pipe through the fastening bolts at both ends of the pipe, thereby quickly connecting and installing the pipe connection hole and underground transmission line of the manhole having various diameters and thicknesses. It can be easily and firmly achieved. Therefore, it is possible to appropriately cope with the change in the state of the underground transmission line to be connected and prevent damage of the underground transmission line.
