“…If this does not happen, then a failure occurs due to the impossibility of destroying the internal bonds between soil particles and overcoming the forces of frontal and side resistance. With limited weight and size parameters of impact devices, the preservation of impact power P is carried out by increasing the impacts frequency f [10] and simultaneously reducing the impacts energy and displacement per impact [8]:…”

The problems of preserving the performance of pneumatic impact machines while reducing their weight and dimensions for carrying out the construction works in a confined space were considered. The results of calculating the dynamics of two variants of impact devices with two and three pneumatic chambers were presented. It was shown the reserve for increasing the impact power is a raise the frequency of impacts due to more number of pneumatic chambers at the same radial dimensions and threshold impact energy of the impact devices under consideration.
