Abstract: Experimental study of air percussion mechanism with two control cameras for use in technologies sinking wells in con-fined spaces vibroimpact means are presented. The test bench and results of an experimental estimation of power and flow rate characteristics of the mechanism are described. Technological capabilities of the airpercussive mechanism at a vertical driving of steel-pipes by diameters of 34-76 mm and dependences of driving velocity on driving depth of pipes are defined.

Key words: pipe air percussive mechanism vibroimpact puncture well driving velocity frequency of impacts
