Abstract

A street grid is provided for surface drainage. The grid includes a frame and a grating, which are adapted to the contours of a paved gully in order to be integrated into the latter, for draining water that flows towards the street grid in a pre-defined flow direction. The aim of the grid is to ensure permanent drainage. To achieve this, recessed inlet openings are provided in the upper edge of at least one lateral wall of the frame in order to guide the water in the flow direction.
