Abstract (en)
[origin: EP1655411A2] The grid has two-dimensional, cast individual units (1, 1`) provided with through-holes and combined with a two-dimensional, horizontally arranged dirt arresting device (5) such as a perforated sheet or a perforated plate. Through- holes of the device with a smaller cross-section are attached to each hole in the units. Each unit is separated horizontally as a covering grid in an upper part, and as a supporting grid in a lower part.
