FIELD: dredging or soil-shifting equipment, particularly dredges or machines for rock building material production, namely for sand and gravel excavation.
SUBSTANCE: erosion device comprises accumulator with nozzles arranged on suction ground receiving means and water supply pipeline connected to the accumulator. Nozzles are arranged along accumulator made as two coaxial pipes. Outer pipe is fixed and provided with arch-shaped windows arranged along the tube. Inner tube may rotate relative outer one and is formed with center of gravity displaced relative axis of it rotation. Inner tube is provided with nozzles arranged in outer tube windows. Window length L is determined as L≥(D/2)·αmax+d, where D is outer pipe diameter, αmax- maximal angle of dredge frame inclination towards horizon, rad., d is outer nozzle diameter.
EFFECT: increased efficiency of soil loosening and enhanced ground intake conditions.
