Description

조립식 맨홀 구조체{ASSEMBLY OF FABRICATED MANHOLE}Prefabricated manhole structure{ASSEMBLY OF FABRICATED MANHOLE}

본 발명은 여러개의 부품으로 분리구성하여 시공현장에서 간단히 조립고정해줄 수 있도록 한 조립식 맨홀 구조체에 관한 것이다.The present invention relates to a prefabricated manhole structure that is configured to be separated into several parts so as to be easily assembled and fixed at a construction site.

일반적으로 맨홀은 지하에 매설된 각종 배수관로나 전기통신관로의 개구부에 설치하여 관로의 유지 및 보수를 위한 작업자의 출입이 가능하도록 하는 시설물로서, 거의 대부분 측면에 흄관의 결합을 위한 연결공을 갖는 맨홀 구조체의 상부 출입구에 맨홀덮개를 결합해주도록 구성된다.In general, manholes are facilities that are installed in the openings of various drainage pipes or telecommunication pipes buried underground to allow workers to enter and exit for maintenance and repair of pipes. It is configured to couple the manhole cover to the upper entrance of the structure.

또한 맨홀구조체는 거의 대부분 콘크리트로 이루어져 대형의 경우 수십톤에 이를 정도로 무게가 매우 무거워 운반성 및 시공성이 떨어지고 또 무게가 무거운 만큼 취급시 파손가능성이 높아지게 된다.In addition, the manhole structure is almost entirely made of concrete, and in the case of a large size, it is very heavy, so transportability and workability are poor, and as the weight is heavy, the possibility of damage is high when handled.

따라서 맨홀 구조체를 연직관과 상부판 및 하부판으로 분리구성하여 시공현장에서 상부판과 연직관의 가이드홀을 관통한 강연선의 하단부는 하부판이 갖는 홀더에 고정해주도록 하고 또 강연선의 상단부는 쐐기를 이용하여 상부판에 고정해주도록 한 등록특허 10-1845523호 '조립식 맨홀 구조체'가 제공된바 있다.Therefore, the manhole structure is divided into a vertical pipe, an upper plate, and a lower plate so that the lower end of the strand that has passed through the guide hole of the upper plate and the vertical pipe at the construction site is fixed to the holder of the lower plate, and the upper end of the strand is made of wedges. Thus, there has been provided a registration patent No. 10-1845523'Assembled manhole structure' to be fixed to the top plate.

그러나 상기한 조립식 맨홀 구조체는 연직관과 상부판 및 하부판이 분리되기는 하나, 사각통형으로 이루어져 무게가 가장 무겁고 부피가 큰 연직관이 일체로 형성되어 있어 여전히 운반성과 시공성이 떨어지게 되고 또 운반 및 보관시 공간활용률이 떨어지게 되며, 무게가 무거운 만큼 운반중 힘이 집중되는 부분이 손상되거나 파손되어 금전적손실을 가져오게 되는 등의 문제점들이 있는 것이다.However, although the above-described prefabricated manhole structure is separated from the vertical pipe, the upper plate and the lower plate, it is made of a rectangular cylindrical shape, and the vertical pipe, which has the heaviest weight and the bulky, is integrally formed, so that transportability and workability are still poor. There are problems such as a decrease in the space utilization rate, and as the weight is heavy, the part where the force is concentrated during transportation is damaged or damaged, resulting in a financial loss.
