SEEPAGE STRUCTURE Russian patent published in 2003 - IPC

FIELD: water supply systems. SUBSTANCE: invention can be used for artificial replenishment of groundwater storage. Proposed seepage structure includes seepage reservoir, water supply system and filtering charge arranged on bottom of reservoir, surface of charge being made crest-like with angle of tilting of side surfaces of crest faces equal to 30-40^o. Water supply system is furnished with divergent nozzles with inner curvilinear spiral conductors connected with feed pipe by means of stand pipes arranged over water surface in reservoir at height of 0.5 m, minimum, and pressure pipelines provided with convergent nozzles at ends with curvilinear screw-like grooves on inner surface of nozzle part and installed at level of crests. Bottom of reservoir has longitudinal slope of 20%, minimum. Ejector is installed on feed pipe. Mixing chamber of ejector is connected by branch pipe with funnel communicating with atmosphere and provided with cycloidal guides on inner surface. Pulsate installed in space of branch pipe is made in form of clothoid with lobes of bimetallic plates freely fitted on vertical axle. EFFECT: increased capacity of structure. 4 dwg
