FIELD: construction.
SUBSTANCE: inventions are related to technology of construction works, are used for trenchless installation of underground communications. Method according to the first version includes striking tool via intermediate body, at that prior to striking its density is increased by means of static loading deformation, and after striking internal pressure is preserved in it. According to the second version of method, density of intermediate body is increased by means of its deformation by striking, and after striking internal pressure is preserved in it. Device is equipped with piston chamber installed between impact action machine and tool. In piston chamber intermediate body is installed, with which impact action machine interacts via piston of this chamber.
EFFECT: increased efficiency of their installation due to control of impact action machine power effect.
