Abstract
A porous hardenable drainage element (14) is produced from a molding compound (10) of expanded plastics granulate and a bonding agent by virtue of the fact that the molding compound is received in a ladle (30) having a pouring opening (32) closed off by a mold bottom (44), the molding compound is pressurized in the ladle, the element (14) is molded from the molding compound in a mold formed by lowering of the mold bottom (44) down into an opening cross section (42) consistent with a cross section of the pouring opening (32), and the element is separated from the molding compound by mutual lateral displacement of the mold and the ladle (30).
Claims12
A method for producing a porous hardenable drainage element from a molding compound of expanded plastics granulate and a bonding agent, the method comprising:
- receiving the molding compound in a ladle having a pouring opening closed off by a mold bottom;
- pressurizing the molding compound in the ladle;
- molding of the element from the molding compound in a mold formed by lowering of the mold bottom down into an opening cross section consistent with a cross section of the pouring opening;
- and
- separating the element from the molding compound by mutual lateral displacement of the mold and the ladle.
A device for producing a porous hardenable drainage element from a molding compound of expanded plastics granulate and a bonding agent, the device comprising:
- a ladle having a pouring opening and displaceable along a plane for the pouring opening;
- and
- a mold comprising an opening cross section consistent with a cross section of the pouring opening and a raisable and lowerable mold bottom for closing off the pouring opening and lowering the molding compound from the pouring opening and down into the opening cross section.
