The plinths (11) are reciprocally spaced apart in the row longitudinal direction. The side wall sections (19) are positioned edge to edge in longitudinal tracks in the plinths with each section bridging over the distance between two adjacently located plinths. The bottom (20) is cast in situ between the side walls with the bottom surface at a level determined by rulers (21) laid on the plinths inside the side walls.
