Abstract
A process and a device for producing concrete pipe by filling and compacting fresh concrete in an upright casting form. An outer jacket surrounding a vibrator-equipped core is rotated around its geometric axis with an internal peripheral speed which is greater than the maximum vibrational speed at which said core acts on the fresh concrete during compaction, said vibrational speed being the product of the amplitude and frequency at which the core vibrates. Around its circumference, the outer jacket has axially distributed roller paths for cooperation with rotationally journalled rollers which can be pressed against them. At least one roller is driven and is a drive means for rotating the jacket, the others being non-driven support rollers. All rollers are mounted on a frame member around the outer jacket of the casting form.
