FIELD: vibration and seismic equipment.
SUBSTANCE: vibration source includes vibration exciter, emitting platform with weights attached to its framework comprising two parts. Each part includes ribs of lateral stiffness in the form of vertical columns with side bosoms and stepped protrusions with bosoms connected to ribs of longitudinal stiffness. Side butts of columns of part of component framework are interjoined. Vibration exciter comes in the form of two synchronized vibrators anchored by wedge-and-screw clamps in cylindrical jackets of component framework. Horizontal screws located in bosoms of vertical columns interlink parts of component framework. Reinforced concrete blocks-weights in steel casings are positioned in spaces between vertical columns and cylindrical jackets. Blocks-weights are pressed against bottoms by screws of beams-weights filled with reinforced concrete and installed in cutouts of stepped protrusions.
EFFECT: enhanced emission efficiency into ground half-space.
