Grid plate for paving lawn during growing stage

摘要

The plate consists of a number of cells (10,30) with walls (11-14,31-33), the top edges of which form the highest points and therefore the walking surface of the slab. The slabs accommodate a load when walked or driven over. They have lower edges, which are connected to a load transfer section (29), and transfer the load into the subsoil or foundations, on which the slabs are layered. Some of the cell walls have horizontal openings (20,20'), so that grass/plant roots can grow through into neighbouring cells. The openings are located in cell walls, which are at angles to the walking surface.
