“…The list of such works includes trenchless pipelaying, strengthening the slopes of foundation pits and embankments, the construction of retaining walls and screens, the formation of pales for the foundations of buildings, supports of bridges, overpasses, and power lines. At the same time, technologies based on the boring of horizontal and vertical wells, and percussion immersion of metal profiles into the ground have become widespread [1].…”

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.

The author reviews briefly existing machines for trenchless laying of underground utilities and vertical driving of steel elements in soil. For a pneumatic hammer with ring and inertia valves for driving different diameter pipes, arrangement and operating principles are described. Powerful longitudinal forces generated by shocks ensure destruction of solid rocks or compaction of soil in the zone of hole-making. These forces can be used in implementation of other technologies as well. For instance, maintenance and rehabilitation of oil well centrifugal pumps, which requires complete disassembling of the machine. For taking of many parts (impellers and guide vanes) out of a hole (a pipe), a pneumatic hammer with piston weight of 40 kg was tested. Another application area of pneumatic hammers can be stimulation of caking material unloading from railway cars using a vibropercussion plant driven by pneumatic puncher. Replacement of the latter by a pneumatic hammer of the same size and performance can enhance efficiency of the process.
