FIELD: construction. ^ SUBSTANCE: flow energy dissipator includes dissipating basin which walls have artificial roughness in the form of semicylindrical gabions. Semicylindrical gabions are laid on anti-suffusion device and have transversal orientation towards water flow direction. Scarp of dissipating basin has concave surface, which generatix is made with step-by-step increase in angular deflection as described by equation where H is the depth of dissipating basin; is final angle of deflection of tangent line towards generatix curve, <90; x is x-coordinate of generatix curve in Cartesian coordinates. ^ EFFECT: improvement of dissipating efficiency in excessive water flow energy. ^ 4 dwg |
