More Information
Summary:According to the present invention, provided is a sealed type manhole cover, which includes: a support installed on a manhole so that the inside is vertically opened and having a ring-shaped caliber expanding hole so that a mounting surface is provided on an upper side of an inner circumferential surface; a ring-shaped inner cover capable of being mounted on the mounting surface of the support; an outer cover having certain weight placed on an upper side of the inner cover; and a packing means inserted into and coupled to the edge of the inner cover to be capable of being compressed by the outer cover. Accordingly, the sealed type manhole cover provides an advantage of being possible to preserve own functions (rainwater introduction and bad smell outflow prevention) even when being frequently opened for repair and inspection. 본 발명에 따르면, 맨홀에 내부가 상하 개방되게 설치되며, 내주면 상측에 안착면이 마련되도록 환상의 구경확장공이 형성되는 받침대; 받침대의 안착면에 안착될 수 있는 환상의 내측 커버; 내측 커버의 상측에 얹혀지는 일정 중량을 갖는 외측 커버; 및 내측 커버의 가장자리에 끼움 결합되어 외측 커버에 의해 압착될 수 있는 패킹수단;을 포함하는 밀폐형 맨홀 뚜껑이 제공된다. 이에 의하면, 보수 또는 점검을 위한 잦은 개방에도 제기능(빗물 유입과 악취 유출 방지)을 보존할 수 있는 장점이 있다.
