Abstract
In the context of the problem of increase in efficiency of vibro-percussion driving of steel pipes in soil, a pilot model of shock generator with step speed adjustment for the bit and anvil impact is described. The authors report experimental modeling of pipe penetration depending on load of stalk. The influence of the stalk load parameters on the amplitude of generated shock pulses and the pipe penetration rate in elastoplastic soil is defined.
