Compaction device and method for compacting ground

A compaction device, comprising:

• at least one traveling drum rotatable about a drum shaft, coupled vibration exciters generating an oscillation torque about the drum shaft, said vibration exciters having unbalanced masses rotating out of phase by 180 degrees in a same direction of rotation, and having a drive shaft running to the drum shaft for driving the vibration exciters,
• wherein the drum is divided into at least two drum parts, wherein the at least two drum parts are substantially adjacent one another, and
• wherein each drum part comprises at least two coupled vibration exciters mounted in the drum at a distance from the drum shaft,
• wherein the drive shafts for the vibration exciters of each of the at least two drum parts are mechanically coupled directly to each other via a transmission or, via a control means, are adjustable to be in-phase ensuring that the vibration exciters of all drum parts always oscillate in synchronism also in case of a turning of the drum parts relative to each other.
