FIELD: construction.
SUBSTANCE: invention is intended for bottom sediment (silt) removal from water pools and for underwater development of mineral resources (sapropel) and bulk materials (sand, gravel, gold placers). Aggregate for bottom sediment removal from pools and underwater development of mineral resources includes bottom sediment conveying device mounted on floating medium and consisting of cylinder linked to pipe string, hollow piston installed inside the cylinder, linked to bar string and featuring channel with funnel-shaped section widening towards intake end and closed by shutoff valve. The floating medium carries conveyor device drive maintaining reciprocal movement of bar string. Aggregate is equipped with V-shaped cutter attached to aggregate opposite of aggregate course direction and serving for cutting mineral deposit layer and concentrating it at intake area. Filter with brushes and rods is attached to the cylinder to prevent large particles from penetrating under valve.
EFFECT: enhanced friability of caked mineral deposits, extended functional capacity and producing efficiency of aggregate.
