The present invention relates to a grid-type grating (G) installed on the top of a drainage cannel for drainage. The grid-type grating (G) is composed of a cover piece (10) positioned on the top of the grid-type grating (G) and including multiple drainage holes (11) to drain waste water or rainwater and to prevent an intake of foreign materials and a fixing means (20) positioned between the grid-type grating (G) and the cover piece (10) and fixating the cover piece (10) and the grid-type grating (G) to adhere to each other. According to this, the cover piece of the grid-type grating is capable of providing excellent appearance as various shapes and patterns can be expressed on the cover piece which can be easily and separately manufactured. In addition, the cover piece of the grid-type grating is capable of being easily manufactured and widely used as a design change of the cover piece is easy and the cover piece is able to be differently configured. Furthermore, the cover piece is capable of effectively preventing the deposition of foreign materials such as sand or waste while reducing time required for installation as the grating and the cover piece can be easily coupled. Accordingly, the present invention provides various effects such as flood damage minimization and the like. |
