FIELD: mining.SUBSTANCE: device of impact action to form wells in soil comprises a body, a hydrohammer with an anvil, a hollow tip in the form of a cylindrical body with a truncated cone, the front end of which is equipped with a circular knife, and four knives installed inside a hollow tip at the angle to each other, as well as nozzles, communications to supply an emulsion solution and a rigidly fixed activator. In the rear part of the body there is an actuating cylinder and a controlled pressure relay to connect discharge manifolds, which tracks and controls joint operation of the hydrohammer and the actuating cylinder.EFFECT: improved efficiency of tunnelling and reduced power inputs for making wells in soil.1 dwg |
