The present invention relates to a manhole cover with improved performance such as lightness, corrosion resistance, and mechanical properties. A manhole cover, which is one aspect of the present invention, has a light weight unlike a manhole cover made of cast iron, and thus is easy to be transported and installed. In addition, the manhole cover, unlike a manhole cover made of cast iron, is free from durability reduction problem by corrosion. Moreover, the manhole cover does not experience a separation phenomenon of a reinforcing material from a rebar due to great binding force between the rebar and the reinforcing material, and thereby has an excellent mechanical properties. The manhole cover comprises a center support unit including the rebar and the reinforcing unit including a reinforcing material placed on the center support unit.
본 발명은 본 발명은 경량성, 내부식성, 기계적 특성 등의 성능이 우수한 맨홀 덮개에 관한 것이다. 본 발명의 일 측면인 맨홀 덮개는 주철로 제조한 맨홀 덮개와는 달리 경량성이 우수하여, 운반 및 설치가 용이하다. 또한, 상기 맨홀 덮개는 주철로 제조한 맨홀 덮개와는 달리 부식에 의한 내구성 저하 문제가 없다. 또한, 상기 맨홀 덮개는 철근과 보강 물질간의 결합력이 우수하여, 철근으로부터 보강 물질의 탈리 현상이 없어, 기계적 물성이 우수하다.
