Method and device for producing a drainage element and drainage element produced thereby |
摘要 |
A porous hardenable drainage element is produced from a molding compound of expanded plastics granulate and a bonding agent by virtue of the fact that the molding compound is received in a ladle having a pouring opening closed off by a mold bottom, the molding compound is pressurized in the ladle, the element is molded 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 the element is separated from the molding compound by mutual lateral displacement of the mold and the ladle. |

1. A device for producing a porous hardenable drainage element from a molding compound of plastics granulate and a bonding agent, the device comprising:
a ladle, for receiving the molding compound, closed off at a bottom by a movable mold bottom that is configured to be lowered into a mold, actuators for lowering the mold bottom downwards to transport part of the molding compound into the mold, and actuators for raising the mold bottom to a predetermined higher level for compressing the porous hardenable drainage element during a molding process, wherein the ladle and the mold are arranged for mutual lateral displacement to separate a molded element from a portion of remaining molding compound in the ladle. |
