Description

조립식 맨홀의 지관연결구조{Structure of connecting a branch pipe to a han-hole casing}Structure of connecting a branch pipe to a han-hole casing}

본 고안은 지하에 매설되는 맨홀에 지관을 연결하는 구조에 관한 것으로, 특히 연결되는 지관을 견고히 고정하고, 연결작업이 정교하고 간편한 지관연결구조에 관한 것이다. The present invention relates to a structure for connecting a branch pipe to a manhole buried underground, and more particularly, to a firmly fixed branch pipe to be connected, the connection work is sophisticated and simple branch pipe connection structure.

맨홀은 지하에 매설된 각종 관의 통풍이나 관거시 작업공간을 마련해주는 시설물로서, 최근에는 도 1에 도시된 바와 같이, 주로 미리 콘크리트 등으로 미리 성형된 상부케이싱(101), 하부케이싱(103)과 및 이들 상하부 케이싱(101,103)사이에 끼워져 맨홀의 전체높이를 조절하는 중간케이싱(102)을 지하에 매설시공하기전에 미리 지상에서 적층하여 고정봉(104)으로 서로 고정하고 접합면끼리 접합재로써 서로 조립한 후 지하에 매립시공한다. The manhole is a facility that provides a work space for ventilation or conduit of various pipes buried underground, and as shown in FIG. 1, an upper casing 101 and a lower casing 103 that are pre-formed with concrete or the like in advance. Intermediate casing 102, which is sandwiched between the upper and lower casings 101 and 103 and controls the overall height of the manhole, is laminated in advance on the ground before being buried and fixed to each other by fixing rods 104, and the joint surfaces are bonded to each other. After assembling, it is buried underground.

그리고 지상에서 맨홀을 조립할 때 지하 배관을 연결접속하기 위한 지관도 함께 조립하게 된다. 이와 같이 맨홀에 지관을 연결할 때 종래에는 통상 도 2에 도시된 바와 같이, 맨홀의 하부케이싱(30)의 측벽에 안쪽으로 갈수록 점차 직경이 감소하는 연결구멍(31)을 형성하고, 상기 연결구멍(31)안에 지관접속관(34)을 삽입하고나서 클램프 등으로 위치이동하지 않도록 고정한 다음, 상기 연결구멍(31)의 안쪽 선단을 밀봉재(35)로 막아서 밀봉처리한다. 그리고서나서 지관접속관(34)이 접속된 연결구멍(31)의 선단과 지관접속관(34)의 틈새를 방수캡(36)으로 덮어 고정밴드(37)로 움직이지 않게 고정한 상태에서, 연결구멍(31)이 확장된 선단 주입구(33)를 통하여 연결구멍(31)과 지관접속관(34)의 외벽 사이 공간에 몰타르를 충전하여 경화시킴으로써 지관접속관(34)을 맨홀(30)의 측벽해 고정해주고, 아울러 연결구멍(31)의 내벽에 구비된 홈(32)에도 몰타르가 침투하여 경화됨으로써 지관접속관(34)이 길이방향으로 힘을 받더라도 연결구멍(31)에서 이탈하지 않도록 잡아주게 된다. When assembling the manhole on the ground, the branch pipes for connecting underground pipes are also assembled. As described above, when connecting the branch pipe to the manhole, as shown in FIG. 2, a connection hole 31 gradually decreases in diameter toward the side wall of the lower casing 30 of the manhole, and the connection hole ( After inserting the branch pipe connecting pipe 34 into the 31, it is fixed not to move by a clamp or the like, and then the inner end of the connecting hole 31 is sealed with a sealing material 35 to be sealed. Then, in the state where the tip of the connecting hole 31 to which the branch pipe connecting pipe 34 is connected and the gap between the branch pipe connecting pipe 34 and the gap between the branch pipe connecting pipe 34 and the fixed band 37 are fixed so as not to move. Through the tip injection port 33 in which the 31 is extended, the mortar is filled and cured by filling the space between the connecting hole 31 and the outer wall of the branch connecting tube 34 so that the branch connecting tube 34 is removed from the side wall of the manhole 30. In addition, the mortar penetrates and hardens into the groove 32 provided on the inner wall of the connection hole 31 so that the branch pipe connection 34 can be held so as not to be detached from the connection hole 31 even though the branch pipe 34 is applied in the longitudinal direction. .

상기한 바와 같이, 종래의 지관연결구조에서는 지관접속관(34)을 맨홀(30)의 측벽에 고정해주는 몰타르를 연결구멍(31)안에 주입할 때 몰타르가 원활하게 주입되지 않으므로 연결구멍(31)의 입구를 일부 확개한 주입구(33)를 통하여 몰타를 충전함으로써 충전되는 몰타르가 먼저 주입된 몰타르를 연결구멍(31)내부로 가압하여 채워 넣게 된다. 그러나 상기 충전되는 몰타르의 양을 지나치게 많게 하면 방수캡(36)의 외부로 흘러넘치게 되고, 반면에 몰타르의 양이 연결구멍(31)의 공간에 비하여 부족하면 상기한 바와 같은 가압충전의 효과를 얻을 수 없어 지관접속관(34)의 결합력이 낮아져 시공후 분리되거나 지관접속관(34)과 연결구멍(31)사이가 완전하게 밀봉되지 않아 그 틈새를 통하여 누설이 생기는 단점이 있었다. As described above, in the conventional branch pipe connection structure, when the mortar fixing the branch pipe connection 34 to the side wall of the manhole 30 is not injected smoothly into the connection hole 31, the connection hole 31 is not connected. By filling the Malta through the inlet 33 of which the inlet of the portion is partially expanded, the mortar to be filled is pressurized into the connection hole 31 to be filled with the mortar. However, if the amount of the mortar is too large to overflow overflows the outside of the waterproof cap 36, on the other hand, if the amount of mortar is insufficient compared to the space of the connection hole 31 to obtain the effect of the pressurized charging as described above. Since the coupling force of the branch pipe connection tube 34 is lowered, the separation force is separated after construction, or the branch pipe connection tube 34 and the connection hole 31 are not completely sealed, so that leakage occurs through the gap.

이에 본 고안은 상기 종래의 지관연결구조가 가진 단점을 해소하기 위하여 지관접속관 또는 지관을 고정하는 몰타르의 주입작업이 간편하면서도 몰타르의 과충전이나 충전부족에 의한 누설등의 불량을 방지할 수 있으면서 지관의 결합력을 높일 수 있는 지관연결구조를 제공함에 목적이 있다. In order to solve the disadvantages of the conventional branch pipe connection structure, the present invention is easy to inject the mortar fixing the branch pipe connecting pipe or the branch pipe, while preventing the defects such as leakage due to overcharging or insufficient filling of the mortar. The purpose is to provide a branch pipe connection structure that can increase the binding force of.

상기 목적을 달성하기 위한 본 고안은 맨홀의 하부 케이싱의 측벽에 지관을 삽입하여 고정하는 지관연결구조에 있어서, 상기 맨홀의 하부케이싱의 측벽에 외측에서 안쪽으로 갈수록 직경이 점차 감소하는 지관연결구멍이 관통되고, 상기 지관연결구멍에는 지관이 끼워져 외측벽과 지관연결구멍사이에 내부공간이 형성되며, 이 내부공간의 한쪽 선단은 밀봉재로써 밀봉되며, 다른 쪽 선단은 지관의 외측에 끼워진 방수캡에 의해 밀봉되며, 상기 내부공간안에는 방수캡의 일측에 구비된 주입구를 통하여 고정몰타르가 충전되어 지관을 맨홀의 하부케이싱에 고정해주는 구조로 된다. The present invention for achieving the above object is a branch connecting structure for inserting and fixing the branch pipe to the side wall of the lower casing of the manhole, the branch connecting hole is gradually reduced in diameter from the outer side to the side wall of the lower casing of the manhole It penetrates through the branch connecting hole, the inner tube is inserted to form an inner space between the outer wall and the branch connecting hole, one end of the inner space is sealed with a sealing material, the other end is sealed by a waterproof cap fitted to the outside of the branch pipe In the inner space, the fixed mortar is filled through an injection hole provided at one side of the waterproof cap, thereby fixing the branch pipe to the lower casing of the manhole.

또한 본 고안은 상기 지관연결구멍의 외측 선단에 환형의 확장부가 형성되어 상기 내부공간에 충전되는 고정몰타르가 상기 확장부안까지 충전되어 경화됨으로써 지관이 길이방향 내측으로 유동하는 것을 저지하게 되어 있다. In addition, the present invention has an annular expansion portion is formed at the outer end of the branch connecting hole is fixed mortar filled in the inner space is filled into the expansion portion and hardened to prevent the branch pipe flowing in the longitudinal direction.

상기한 바와 같은 본 고안에 따르면 방수캡에 형성된 주입구가 외부로 돌출되게 구비되어 몰타르의 주입작업이 간편하면서도 몰타르의 과충전이나 충전부족에 의한 누설등의 불량을 방지할 수 있고, 몰타르가 적정하게 주입됨으로써 지관과 맨홀의 연결구멍사이에 틈새가 발생하지 않아 누설을 방지할 수 있음과 아울러 지관의 결합력을 높일 수 있고, 지관연결구멍의 입구에 형성된 확장부에 충전된 몰타르가 경화되어 지관의 길이방향 유동을 잡아주게 된다. According to the present invention as described above, the injection hole formed in the waterproof cap is provided to protrude to the outside to facilitate the injection of the mortar, while preventing the defects such as leakage due to overcharging or insufficient filling of the mortar, and injecting the mortar appropriately As a result, a gap does not occur between the connecting pipe of the branch pipe and the manhole, preventing leakage and increasing the binding force of the branch pipe, and the mortar hardened in the expansion portion formed at the entrance of the branch pipe hole is hardened, thereby extending the length of the branch pipe. To catch the flow.
