FIELD: construction.
SUBSTANCE: thin-walled steel shells 2 are installed into a dense waterproof soil 1 to the bottom of the water area. Vibration engineering means are fixed on the free end of shells 2 by means of connection elements. Vibration engineering means are made in the form of free springless vibratory hammers 4. Connection elements are made in the form of fork guides. Deepening of thin-walled steel shells 2 is carried out in vibration impact low frequency mode with impact mass bounce. Free springless vibratory hammers 4 are suspended via rods 5 with springs 6 onto a stiff crossbeam-surcharge 7 for additional static load against dense waterproof soil 1 and stable mode of operation of free springless vibratory hammers 4.
EFFECT: invention provides for fatigue breakdown of dense waterproof soil and reduced forces of head resistance of soil against deepening of thin-walled steel shells into it.
