PURPOSE: A water-soluble sheet for a sewer grating cover, and a clip for installation thereof are provided to prevent inner offensive odor of a sewer from being diffused to the outside when normal times, and allow rainwater to be entered to inside of the sewer when rainy days. CONSTITUTION: A water-soluble sheet for a sewer grating cover(30) is composed of a water-soluble material, and formed in a sheet shape bigger than a width of a sewer grating. A clip for installation of the water-soluble sheet is formed in a C-shape of an upper part, a left wing part, and a right wing part to clamp a longitudinal frame, a horizontal frame of the grating or a horizontal plate. Through holes are formed in the center of the left wing part and the right wing part at certain intervals. The horizontal plate of the grating or a joint bar is penetrated through the through holes. |
