Abstract
Aimed to improve capacity of vibro-percussion driving of steel pipes in soil, the authors describe experimental modeling of the process with additional vibration exciters of axial and transverse vibrations series-linked to impulsive load source. Workability of combination of two extended action spectrum percussion units as the vibration exciter is illustrated.
