METHOD FOR ERECTION OF HYDRAULIC FLUME WITH POLYGONAL CROSS-SECTION Russian patent published in 2008 - IPC E02B5/02 

FIELD: construction.

SUBSTANCE: method for hydraulic flume erection includes executing of excavation and construction of side walls and bottom of flume in reinforced concrete facing. Bottom is made triangle-shaped with top at center, recessed by value of h₂=α·h₁,_{where α is relative depth, where h1 is chute depth without regard to bottom recess and tolerance of upper flume edge altitude over water level, m; m2 is batter of bottom slopes. On flume bottom on the top of reinforced concrete facing of bottom slopes revetment of polymer concrete and river cobblestone is arranged. Cobblestone is laid in rows along bottom slopes line across flume with decrease of its sizes from center to side walls sole. Along and across cobblestone rows reinforcement bars are installed which form laced cover with cell sizes less than cobblestone cross section. Lacing is attached to anchors emplaced in reinforced concrete walls and in flume base. Lower parts of cobblestones are embedded by polymer concrete throughout the whole area of bottom slopes.}

EFFECT: increase of hydraulic flume operation efficiency and reduction of material costs for its construction and operation.
