Abstract: A counter-rotating compaction head for manufacturing a concrete pipe is vertically positioned in a vertical mold within the longitudinal axis of the mold so as to be rotatable about and axially slidable along the longitudinal axis of the mold. The counter-rotating compaction head has a distributing head with distributing devices for distributing concrete and a cylindrical mantle. A first drive shaft rotates the distributing head. A smoothing piston with a smoothing mantle is rotatably driven by a second drive shaft counter to the distributing head. At least one vibrator for compacting and smoothing an inner wall surface of the concrete pipe to be manufactured is operatively connected to at least one of the cylindrical mantle of the distributing head and the smoothing mantle of the first smoothing piston so as to vibrate the respective mantle.
