  • Patent number: 11459724
    Abstract: The invention relates to a method for producing a sealing base in the ground in which by injection of a curable grouting compound a plurality of sealing elements is produced in a first soil layer, which elements adjoin one another or overlap, wherein the plurality of sealing elements forms a solid base plate following curing of the grouting compound. It is provided according to the invention that in a second soil layer, which lies beneath the first soil layer for the solid base plate, a gel base is created by injection of a sealing gel, and that the solid base plate and the underlying gel base form the sealing base. The invention further relates to a correspondingly produced sealing base.

  • Patent number: 10639715
    Abstract: The present invention relates to a method and a device for producing three-dimensional objects based on computer-provided data. Material is extruded on a surface of a workpiece (e.g., in two-dimensions). The workpiece is then moved incrementally so that additional material can be extruded on the new surface of the work piece. These steps are repeated until the 3-dimensional object is completed. The present invention also relates to a device including an extruder system for extruding a build material in multiple directions on a surface of a workpiece, and a conveying component for moving the workpiece incrementally for extruding additional material on the new surface. The method and device preferably allows for the continuous construction of three-dimensional objects.
