Description

부관 맨홀{Installation drop manhole}Lieutenant Manhole {Installation drop manhole}

본 고안은 부관 설치공사의 공기단축, 시공품질의 향상, 하수 본관의 유지, 부관의 하부 침하 방지, 교통장애 및 위험요인 감소 등을 위한 부관 맨홀에 관한 것이다.The present invention relates to a subsidiary manhole for reducing the air of the subsidiary installation, improving construction quality, maintaining the sewage main, preventing subsidence of the subsidiary, and reducing traffic obstacles and risk factors.

하수관거의 경사가 심하면 유속이 빨라져서 관거의 손상과 내용연수의 단축이 예상된다. 이런 문제를 해소하기 위하여 적당한 간격마다 단차 맨홀을 설치하게 된다. 이러한 단차 맨홀을 설치할 때 단차로 인하여 유속이 빠르면 맨홀의 내용연수가 단축되고 맨홀내 유지보수등의 작업에 지장을 받는다. 그래서 경사가 심한 하수관거에 있어서는 도 1과 같이 맨홀(1)에 이르는 유입측 하수관(2)상에 맨홀(1)내부로 통하는 부관(3)을 설치하도록 관련법에 규정되어 있다.If the slope of sewage pipes is too steep, the flow rate will increase, leading to damage and shortening of service life. In order to solve this problem, stepped manholes are installed at appropriate intervals. When installing the stepped manhole, if the flow velocity is high due to the stepped, the service life of the manhole is shortened and the work of the manhole maintenance, etc. is hindered. Therefore, in the sewage pipe with a high inclination, the related law is provided to install an auxiliary pipe 3 which passes into the manhole 1 on the inflow side sewer pipe 2 leading to the manhole 1 as shown in FIG.

이처럼 맨홀 밖 하수관거상에 부관을 설치하는 것은 개착공사가 불가피한데, 대부분의 하수관이 도로를 따라 설치되어 있으므로 도로를 개착하고 공사를 시행할시에는 모든 도로공사가 그러하듯이 교통장애를 유발하고 보행자의 보행안전을 위협하는 등 민원이 제기되며, 대체로 공기가 길어지고, 시공품질이 낮은 반면에 시공비는 높다. 또, 부관을 접속하기 위한 접속공을 하수 본관에 천공해야 되므로 본관의 손상이 불가피하할 뿐만아니라 시공 후 부관의 하부 침하를 방지할 대비책도 마땅찮다.In this way, it is inevitable that the installation of the auxiliary pipe on the sewer pipe outside the manhole is inevitable, but since most sewer pipes are installed along the road, when the road is opened and the construction is carried out, as in all road construction, it causes traffic obstacles and pedestrians. Civil complaints are raised, threatening the safety of walking, and the construction cost is high while the air is long and construction quality is low. In addition, since the connection hole for connecting the secondary pipe must be drilled in the sewage main building, damage to the main building is inevitable, and preparation for preventing the subsidence of the secondary pipe after construction is also appropriate.

본 고안은 부관 설치공사의 공기단축과 시공품질 향상, 하수 본관의 무손상, 부관의 하부 침하 방지, 유지보수의 용이성, 저비용, 및 교통장애와 보행자안전의 위해요인 감소 등에 유효한 부관 맨홀을 제공하기 위한 것으로서, 맨홀의 유입구측 맨홀 외부쪽에 설치하던 부관을 맨홀 내부에 설치하는 것을 특징으로 한다.The present invention provides an ancillary manhole that is effective in improving the air shortening and construction quality of the ancillary installation, preventing damage to the sewage main building, preventing subsidence of the secondary pipe, ease of maintenance, low cost, and reducing hazards of traffic obstacles and pedestrian safety. For this purpose, it is characterized in that the auxiliary pipe which was installed on the inlet side manhole outside of the manhole is installed in the manhole.

<도면의 주요부분에 대한 부호의 설명><Explanation of symbols for main parts of the drawings>

1 : 맨홀 2 : 하수관1: manhole 2: sewer pipe

3 : 부관 4 : 유입구3: adjutant 4: inlet

5 : 물받이 6 : 부관 접속부5: drip tray 6: subsidiary connector

도 2와 도 3에서, 바닥에 부관 접속부(6)가 형성된 물받이(5)를 맨홀(1)의 유입구(4)안쪽에 설치하고, 상기 부관 접속부(6)에 부관(3)의 상단을 올려 끼워서 고정하며, 부관(3)은 유입구(4)측 벽에 세트 앵커(7)와 밴드(8)를 이용하여 안정시킨다.2 and 3, a drip tray 5 having an auxiliary pipe connecting portion 6 formed on the bottom is installed inside the inlet 4 of the manhole 1, and the upper end of the auxiliary pipe 3 is placed on the auxiliary pipe connecting portion 6. The fitting pipe 3 is stabilized by using the set anchor 7 and the band 8 on the inlet 4 side wall.

도2.물받이(5)는 돌출곤크리트 구조물로 관경이 500mm이상에서 사용하고,도4.돌출관 물받이 이경티(5a)는 접속관 관경이 500mm이하에서 사용하며, 물받이 및 이경티(5,5a)의 재료로 콘크리트제와 합성수지제, PC제 등이 있고, 콘크리트제나 PC제 물받이(5)의 경우 물받이(5) 바닥 상면으로 돌출된 부관(3)의 상단 사이에 생기는 단차는 인버트 몰탈(9)로 보정하고, 물받이(5)가 합성수지 제품인 경우에는 우레탄 등 합성수지와 친화성있는 물질로 보정한다.2, the drip tray 5 is a protruding concrete structure with a diameter of 500 mm or more, and Fig. 4. The projection pipe drip tee 5a is used with a pipe diameter of 500 mm or less, and the drip tray and the tee tee 5, The material of 5a) includes concrete, synthetic resin, and PC. In the case of concrete or PC drip tray (5), the step difference between the top of the sub pipe (3) protruding from the bottom of the drip tray (5) is inverted mortar ( 9) and if the drip tray (5) is a synthetic resin product, correct it with a material compatible with synthetic resin such as urethane.

상기 부관(3)은 가볍고 유지보수가 간편하며 가공하기 쉽고 가격면에서 유리한 합성수지 관이다.The sub pipe 3 is a synthetic resin pipe that is light in weight, easy to maintain, easy to process and advantageous in terms of price.

도 4는 상기 물받이(5)를 이경 티(5a)로 대체한 경우를 나타낸 것이다. 이경 티(5 a)란 맨홀(1)의 유입구(4)와 지름이 같고 저면에 부관용 접속부(6)를 가진 티를 말한다.4 shows a case in which the drip tray 5 is replaced with the tee 5a. The other diameter tee 5a means a tee having the same diameter as the inlet 4 of the manhole 1 and having a connection part 6 for the sub-pipe on the bottom.

상기와 같이 큰 단차로 인한 부작용을 해소하기 위한 부관을 맨홀내에 설치함으로서 얻어지는 효과로서는 우선 맨홀의 유입측 하수관을 드러내고 부관을 설치할 지중 구멍을 파지 않아도 되므로 공기가 대폭 단축되고 시공비도 크게 절감된다.As an effect obtained by installing an auxiliary pipe in the manhole to solve the side effects caused by the large step as described above, first, the inflow side sewer pipe of the manhole is not exposed, and the underground hole to install the auxiliary pipe is not required to be greatly shortened and the construction cost is greatly reduced.

또, 교통장애를 유발하거나 보행안전을 해칠 우려가 없으므로 민원이 발생할 빌미를 제공하지 않으며, 유입측 하수관을 조금도 손상시키지 않고 깔끔하게 부관을 설치할 수 있으므로 시공품질이 우수하고, 부관을 맨홀에 고정하므로 시공 후 하부가 침하될 우려가 없다.In addition, since there is no risk of causing traffic obstacles or impairing pedestrian safety, it does not provide an opportunity for civil complaints, and it can be installed neatly without damaging the inflow sewer pipe, so the construction quality is excellent, and the construction is fixed to the manhole. There is no fear that the lower part will sink afterwards.
