Disclosed is a manhole cover with improved watertightness. A manhole cover according to an aspect of the present invention includes: a frame forming a manhole opening; a cover mounted to cover the manhole opening; and an elastic member inserted between the frame and the cover. The frame includes a longitudinal supporting unit supporting the cover and a transverse supporting unit formed into a shape corresponding to the cover to receive the cover along the outer circumference of the cover. The elastic member is inserted between the cover and the transverse supporting unit. A manhole cover including a cover, a frame, and an elastic member according to a partial embodiment of the present invention is capable of preventing a water leakage by maximizing watertightness, thereby protecting expensive cables and electronic equipment installed inside a manhole from rainwater, running water, and the like. In addition, the effects of making a process of checking defects of the elastic member (300) remarkably easier than an existing technology and conveniently performing a process of replacing the elastic member (300) without separating the cover (100) are obtained. Furthermore, the manhole cover is capable of providing not only an effect of preventing the water leakage, but also the effects of preventing noise due to external impact and preventing the separation of the cover by sealing the cover with the frame. |
