  • METHOD AND DEVICE FOR PRODUCING A DRAINAGE ELEMENT AND DRAINAGE ELEMENT PRODUCED THEREBY
    Publication number: 20160067892
    Abstract: 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.
