INWASH WASTE POND Russian patent published in 2011 - IPC E02B7/06 

FIELD: construction.

SUBSTANCE: waste pond comprises a section of primary stocking, a ground reservoir of which is formed by barrier dams tier by tier, and an adjacent section of subsequent stocking, the ground reservoir of which is formed by barrier dams tier by tier and a board of the primary stocking section. The pond also comprises an inwash system, which ensures wastes inwash into a tier of the section, a water-intake facility that provides for water-intake from a settling pond, and a drainage water conduit that supplies this water into a system of water reuse of wastes hydraulic transport. The water-intake facility includes two buckets that form a pair and adjoin the barrier dam of the primary stocking section at different sides. One bucket of the pair is arranged in wastes of the beach zone in the primary stocking section, and is connected by a channel to the settling pond of this section, and the other one is arranged in wastes of the beach zone of the subsequent stocking section, and is connected by a channel to the settling pond of this section. In one bucket of the pair there is a floating pump station, the pump of which is hydraulically connected to an influent chamber of the pump station, and by means of an additional water conduit - to a floating influent chamber arranged in the other bucket of this pair. Length of channel section that changes in process of wastes washing from inlet rise formed by wastes to floating influent chamber or an influent chamber of the pump station i_k meets the following criterion: i_k≥(h_s-h_r), where h_s - specified depth of water upstream the influent chamber; h_r - depth of water at the inlet rise of the channel; under - average inclination of surface in underwater inwash of wastes.

EFFECT: improved reliability of the wastes pond.
