본 발명은, 도면에 도시된 바와 같이, 지중배전선로의 맨홀 접속부에서 폴리에틸렌 파형관을 보호하면서 이 접속부를 보강하는 맨홀의 접속부 보강 구조에 있어서, PVC 보강관(1)의 한쪽 선단에 폴리에틸렌 파형관(2)을 고정하는 고정링(3a)을 갖추고 타단에는 맨홀(4) 벽에 고정시키는 앵커볼트(5)가 체결되는 플랜지(6)가 형성되며, 상기 맨홀(4)의 반대쪽 벽에는 맨홀 구멍(7)을 연장 관통하여 설치되는 폴리에틸렌 파형관(2)을 고정시키는 다른 고정링(3b)이 설치되어 이루어진 구조로 되어 있다.The present invention, as shown in the figure, in the connection portion reinforcement structure of the manhole to reinforce the connection while protecting the polyethylene corrugated pipe at the manhole connection portion of the underground distribution line, the polyethylene corrugated pipe (2) at one end of the PVC reinforcement pipe (1) ) And a flange (6) to which anchor bolts (5) fastening to the wall of the manhole (4) are formed at the other end, and a manhole hole (7) on the wall opposite to the manhole (4). ) And another fixing ring (3b) for fixing the polyethylene corrugated pipe (2) to extend through) is provided.

여기서, 상기 고정링(3a, 3b)에는 방수용 고무(8)가 끼워지고, 상기 고정링 (3a)과 다른 고정링(3b) 사이에는 방수재(9)가 충진되어진다.Here, the waterproof rubber 8 is fitted into the fixing rings 3a and 3b, and the waterproofing material 9 is filled between the fixing ring 3a and the other fixing ring 3b.

따라서, 본 발명에 따른 플랜지 일체형 보강관 구조는 맨홀(4)과 폴리에틸렌 파형관(2)의 접속부에 외부하중 및 자중으로 인해 발생할 수 있는 관의 변형과 처짐 현상을 방지시킬 뿐만 아니라, 상기 폴리에틸렌 파형관(2)에 접하여 설치되는 고정링(3a, 3b)들은 맨홀(4)의 내부로 인입된 폴리에틸렌 파형관(2) 부분과 본 발명에 따른 플랜지 일체형 보강관에서 나오는 부분을 잡아주어 고정시키면서 고무재질의 방수재(9) 및 방수용 고무(8)와 함께 방수를 보다 효율적으로 수행하도록 되어 있다.Therefore, the flange-integrated reinforcement pipe structure according to the present invention not only prevents deformation and deflection of the pipe, which may occur due to external load and self-weight at the connection portion of the manhole 4 and the polyethylene corrugated pipe 2, 2) Fixing rings (3a, 3b) are installed in contact with the rubber corrugated pipe (2) part of the manhole (4) and the rubber material waterproofing while holding the part coming out of the flange integral reinforcement pipe according to the present invention (9) and the waterproof rubber (8) are designed to perform waterproofing more efficiently.

다음에는 본 발명이 맨홀(4)에 시공되는 방법을 설명한다.Next, the method by which the present invention is constructed in the manhole 4 will be described.

상기 PVC 보강관(1)의 플랜지(6)를 맨홀(4)의 벽면 설치위치에 앵커볼트(5)를 이용하여 고정시킨다. 이어 폴리에틸렌 파형관(2)을 상기 PVC 보강관(1)을 통해 맨홀(4) 내부로 인입시키고, 상기 맨홀(4) 내부로 인입된 폴리에틸렌 파형관(2) 부분의 고정과 방수를 위해 방수용 고무(8)를 상기 폴리에틸렌 파형관(2)의 골 사이에 위치시키고 고정링(3b)을 이용하여 감싼 다음, 이 고정링(3b)에 장착된 볼트(11)를 조임으로서 맨홀(4) 내부쪽의 설치를 완료한다.The flange 6 of the PVC reinforcement pipe 1 is fixed to the wall mounting position of the manhole 4 by using an anchor bolt 5. Then, the polyethylene corrugated pipe (2) is introduced into the manhole (4) through the PVC reinforcement pipe (1), and the waterproof rubber (8) for fixing and waterproofing the portion of the polyethylene corrugated pipe (2) introduced into the manhole (4) ) Is placed between the valleys of the polyethylene corrugated pipe (2) and wrapped using the fixing ring (3b), and then tighten the bolt (11) mounted on the fixing ring (3b) to install the inside of the manhole (4) To complete.

그리고, 상기 PVC 보강관(1)과 폴리에틸렌 파형관(2) 사이의 빈 공간에 방수재(9)를 충진한 후, 상기 PVC 보강관(1) 외측으로 나와 있는 폴리에틸렌 파형관(2)의 고정 및 방수를 위해 방수용 고무(8)를 위치시키고 고정링(3a)으로 이를 감싼 다음, 볼트(11)로 조여 설치한다.
또한, 상술한 바와 같이, 기존의 콘크리트 파형관은 그 재질이 콘트리트와 폴리에틸렌(PE)으로 강성에 차이가 있으나, 본 발명에 따른 보강관과 파형관은 그 재질이 PVC와 PE로 같은 염화비닐계 재료이기 때문에 강성에 차이가 없어 응력집중이 발생되지 않는다.Then, after filling the waterproof material (9) in the empty space between the PVC reinforcement pipe (1) and the polyethylene corrugated pipe (2), fixing and waterproofing of the polyethylene corrugated pipe (2) extending out of the PVC reinforcement pipe (1) Position the waterproof rubber (8), wrap it with a fixing ring (3a), and then install by tightening with a bolt (11).
In addition, as described above, the conventional concrete corrugated pipe has a difference in the rigidity of the concrete and concrete (PE), the reinforcement pipe and corrugated pipe according to the present invention is a vinyl chloride-based material such as PVC and PE Therefore, there is no difference in stiffness and stress concentration does not occur.

끝으로 모래(10)를 이용하여 다짐도 85% 이상으로 되메움을 한다.Finally, the sand 10 is backfilled to 85% or more of compaction.

본 발명에 따른 플랜지 일체형 보강관으로 시공할 경우, 다음과 같은 장점을 얻을 수 있다. When constructing a flange-integrated reinforcement tube according to the present invention, the following advantages can be obtained.

첫째로, 간단한 조립작업만으로 시공이 완료되고, 바로 모래를 이용해 되메움하기 때문에 콘크리트 타설공법의 단점인 콘크리트 치기작업과 양생에 필요한 시간이 생략되어 신속한 시공이 가능하다.First, the construction is completed only by simple assembly work, and since it is directly filled with sand, the time required for concrete stroke and curing, which is a disadvantage of the concrete pouring method, is omitted, and thus rapid construction is possible.

둘째로, 콘크리트 치기에 필요한 인력 및 콘크리트 물량이 필요하지 않기 때문에 경제적이다.Secondly, it is economical because it does not require the manpower and concrete quantity required for concrete striking.

셋째로, 맨홀과 폴리에틸렌 파형관 사이의 접속부를 없애고, 맨홀에 폴리에틸렌 파형관이 인입되는 부분에 플랜지 일체형 보강관을 설치하였기 때문에 구조적 안정성을 극대화시킬 수 있다.Third, since the connection part between the manhole and the polyethylene corrugated pipe is removed, and the flange integral reinforcement pipe is installed at the part where the polyethylene corrugated pipe is inserted in the manhole, structural stability can be maximized.

넷째로, 이중의 방수공법(방수재 충진, 방수용 고무)을 적용하였기 때문에 맨홀안으로 물이 유입되는 현상을 방지할 수 있다.Fourth, since a double waterproof method (water repellent filling, waterproof rubber) is applied, the phenomenon that water flows into the manhole can be prevented.

다섯째로, 사후 관로에 문제가 발생했을 경우 콘크리트가 아닌 모래로 되메움을 했고, 플랜지 일체형 보강관 설치도 간단한 볼트작업에 의해 이루어졌기 때문에 보수가 편리하다.Fifthly, if a problem occurs in the after-pipe, it is backfilled with sand, not concrete, and the flange-integrated reinforcement pipe is also installed by simple bolting, which is convenient for maintenance.
