FIELD: geophysics. ^ SUBSTANCE: device has rigid, positioned on soil, emitting plate, device for its pressing to soil, load, resilient element, connecting emitting plate to load, and source of alternating-sign force of variable frequency, made in form of two-tact electric magnet, windings of which are connected to electric power grid. Turn-by-turn feed of current pulses into windings of two-tact electric magnet is a reason for occurrence of alternating-sign force effects, transferred to soil through emitting plate and exciting seismic waves in soil, frequency and amplitude of which is set by current pulses formed by electric power grid. ^ EFFECT: higher efficiency, simplified construction. ^ 9 dwg |
