SUBSTANCE: invention relates to the design of a water intake grate for a prefabricated storm sewer gutter. The water intake grate is made in the form of a carrier frame, equipped with longitudinal rods and ribs placed perpendicularly to them. The ribs on the lower side of the grate have support places designed to bear on the upper surface of the profiles fixed to the body of the tray with fasteners. The support places have a longitudinal cutout along the entire length of the grating, provided with lower recesses. The specified cutout is made with the possibility placing in it the upper parts of the fastening elements of the profiles, which attract the profiles to the side walls of the tray body. The lower recesses are made with the possibility of accommodating nuts attached to the upper surface of the profiles. In the upper part of the grid, coaxially with the lower recesses, upper recesses are made with the possibility of placing bolt heads in them for attaching the grille to the profile by screwing said bolts into said nuts. Said upper and lower recesses are connected by holes with the possibility of accommodating said bolts.

EFFECT: increase reliability and service life of the entire structure of the storm drain gutter by evenly distributing the operating loads transmitted to the grate and to the entire structure of the gutter storm sewer.
