The present invention is accomplished by providing a cover installed to cover a drainage, which is implemented to drain water when it rains, on a park or a backside road. The cover is for covering a drainage, which is a civil structure installed to drain water on a park or a backside road, when it rains, and has an open upper surface, and comprises: a pair of frames which are made of an L-like section steel and arranged to be parallel with each other with a spacing between them; unit bearing plates which are cut in square plates and horizontally installed between the frames to support the frames; non-slip elements which are arranged in parallel along with a length direction on respective upper surfaces to form a small-width stripe shape preventing a water-film phenomenon and a slip on an icy surface; and an engaging element which engages the frames with the bearing plate. According to the present invention, a slip accident due to a water-film phenomenon and ice is prevented. |
