Abstract
A device and a method for the production of multi-layer concrete pipes, particularly two-layer concrete pipes. The device has a first stand, in which a first pressing head that can be driven is mounted, a turntable, on which several mold mantles standing vertically can be pivoted into a stand in cycles, and a first charging system for filling a first concrete mixture into one of the mold mantles. A second pressing head having an outside diameter that is smaller than that of the first pressing head, and a second charging system for filling a second concrete mixture into one of the mold mantles are provided. In this manner, the second concrete mixture can be filled into the mold mantle, by the second charging system and the mixture can be distributed and compacted before the concrete pipe is removed from the mold mantle.
