Description

조립식 맨홀{Fabrication manhole}Prefabricated Manholes {Fabrication manhole}

본 고안은 지하에 매설되는 각종 배관이나 선로를 보호하기 위해서 일정 구간마다 설치되는 조립식 맨홀에 관한 것으로, 더욱 상세하게는 몸체를 다단계로 분리 성형하고 이들을 각각 볼트와 너트를 이용하여 외부에서 조립설치토록 함으로써, 전체적으로 제조가 손쉽고 설치가 편리하며, 설치후에는 조립이 견고하여 수명이 장구하도록 한 조립식 맨홀에 관한 것이다.The present invention relates to a prefabricated manhole that is installed every certain section in order to protect various pipes or tracks buried underground. More specifically, the body is separated and formed in multiple stages and these are assembled and installed from the outside using bolts and nuts, respectively. The present invention relates to a prefabricated manhole, which is easy to manufacture and convenient to install, and that the assembly is robust after installation, thereby providing a long service life.

일반적으로, 맨홀은 제수변을 비롯하여 지하에 매설되는 각종 상.하수도 배관이나 선로를 보호하기 위해서 일정 구간마다 설치되는 지중 구조물로써, 제수변이나 상,하수도 배관이나 선로를 보호하고 이들이 노후되었을때 배관의 교체나 수리와 같은 공사를 원활하게 할 수 있도록 하기 위해서 설치된다.Generally, manholes are underground structures that are installed at certain intervals to protect various water and sewage pipes and tracks that are buried underground, including sewage valves. It is installed to be able to do construction such as I repair smoothly.

그런데 종래의 대부분의 맨홀들은 그 몸체 구조가 거의 단일체로 구성되어 있어서 제조가 어렵고, 부피가 크고 중량이 많이 나가서 운반 및 설치가 용이하지 못하였음은 물론, 몸체중 어느 한 부분이라도 파손이나 훼손이 되게되면 이를 수리하기가 어려워 보통 전체를 한꺼번에 교체하여야 하므로 교체 및 수리가 까다롭고번거로운 것은 물론 교체비용이 많이 드는 등의 여러가지 문제점이 있었다.However, most of the conventional manholes are difficult to manufacture because their body structure is composed of almost one body, and they are not easy to transport and install due to their bulky and heavy weight, and any part of the body may be damaged or damaged. When it is difficult to repair it, it is usually difficult to replace the whole at a time, so it is difficult to replace and repair, and there are various problems such as expensive replacement.

이에 맨홀을 구성하는 몸체를 여러부분으로 분리성형하고 이들을 결합하여 사용토록 안출된 것들도 있었으나 이들은 모두 그 구조가 전체적으로 복잡하여 제조가 어렵고, 조립이 용이하지 못하였으며, 조립부분에 누수를 방지하고자하는 별다른 장치가 없어서 이부분을 통해 맨홀내부로 누수가 되는 경우가 허다하였다.There were some parts of the body constituting the manhole separated and molded to combine them, but all of them are difficult to manufacture, easy to assemble, as a whole of the structure is complex, it is a different Since there is no device, it is often leaked into the manhole through this part.

본 고안은 상기와 같은 종래의 제반 문제점을 해결하기 위해서 안출한 것으로,The present invention has been devised to solve the conventional problems as described above,

맨홀몸체를 다단계로 분리 성형하고 이들을 각각 볼트와 너트를 이용하여 외부에서 견고히 조립설치토록 함으로써, 전체적으로 제조가 손쉽고, 운반이 용이하며, 설치가 편리함은 물론, 설치후에는 조립이 견고하여 수명이 장구하도록 한 고품질의 맨홀을 제공하여 편리하게 사용토록 함에 그 목적을 둔 것이다.By separating and molding the manhole body in multiple stages, and installing them firmly from the outside using bolts and nuts, they are easy to manufacture, easy to carry, and easy to install, and they are easy to assemble after installation. The aim is to provide a high quality manhole for convenient use.
