Abstract (en)
[origin: EP0551634A1] Process and device for making concrete bricks with continuous narrow holes for water drainage (hollow bricks), the bricks being made in at least one mould which is filled with concrete and is mounted on a moulding table, and at least one ram, which corresponds to the mould, for compacting the concrete. To produce the narrow holes, there are arranged, in the region of the rams or of the moulding table or of the mould, perforating pins which are guided inside the mould before the compaction of the concrete. Subsequently, the concrete is compacted, the perforating pins are removed from the region of the mould, the compacted concrete bricks are removed from the mould completely and the concrete bricks are hardened. <IMAGE>
