FIELD: hydraulic structures, particularly intake structures to take water for economic needs. ^ SUBSTANCE: front-entrance river water intake comprises spillway dam and water intake with two or more parallel setting chambers and transversal water-accumulation gutter having bottom located over water surface during setting chamber flushing. Width of side setting chamber in plane view in stream direction gradually increases in accordance with the equation y=(2h/S2 ch)(x2/2), where h is assumed expansion in the end of side setting chamber, Sch -s length of side setting chamber. Side walls of transversal water-accumulation gutter may rotate about fixed axis by means of driving mechanism. ^ EFFECT: possibility to increase water cleaning efficiency due to transversal water-accumulation gutter wall rotation and possibility of water taking from upper, clean, layers inside setting chambers. ^ 8 dwg |
