Abstract
The relevance of using pneumatic impact machines in conditions of confined technological space is justified. Examples of pipe driving into soil by means of small-sized pneumatic impact machines are presented. Vibratory percussive penetration of vertical pipes with different diameter was physically simulated, the results are presented. The effectiveness of using an experimental model of pneumatic impact machine with two controllable chambers for driving pipes in soil is proved.
