FIELD: construction.
SUBSTANCE: device comprises an underwater vessel with atmospheric pressure of air, a trolley, a pulp line with a cone-shaped mixer and a jacket, a bracket with a trolley and a jacket, a vertically arranged working organ with a hydraulic motor, its shaft and tillers. On the shaft of the hydraulic motor there is a conical body, tillers are made in the form of cutters and fixed on the conical body. On the side surface of the conical body there are through holes with transverse size of not less than concretion size. The conical body with cutters is installed below the horizontal input section of the mixer. The bracket is connected with the trolley by means of a rotary hydraulic cylinder with the vertical axis of rotation.
EFFECT: increased efficiency of a soil intake device due to achievement of continuity of the process for production of minerals at the specified area of the water reservoir bottom.
