STORM DRAIN GUTTER Russian patent published in 2022 - IPC E01C11/22 E03F5/06 

FIELD: constructions.

SUBSTANCE: invention relates to the design of a storm sewer gutter assembly. The storm sewer gutter includes a gutter body, a plurality of water intake grates, L-shaped profiles. The body of the tray is made in the form of a reinforced concrete bearing element with two side walls. In the upper part of each side wall, recesses with a horizontal support surface and a vertical surface are made on its inner side. L-shaped profiles are installed on the horizontal support and vertical surfaces, the horizontal part of which is fixed to the tray body by fasteners. Each water inlet made in the form of a supporting frame, equipped with longitudinal rods and ribs placed perpendicularly to them. Nuts are attached to the upper surface of the horizontal part of the L-shaped profiles with the possibility of fixing water intake grates in them by means of bolts. The ribs on the underside of each grate have support points for resting on the upper surface of the horizontal part of the L-shaped profiles. The supporting places have a cutout along the entire length of the grating. The cutout is made with the possibility of placing in it the upper parts of the fasteners L- shaped profiles and is provided with lower notches of the lattice for placing nuts of L-shaped profiles in them. In the upper part of each grille, coaxially with the lower recesses of the grille, upper recesses of the grille are made with the possibility of placing bolt heads in them for attaching the grille. Said upper and lower recesses are connected by holes with the possibility of accommodating said bolts.

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