FIELD: construction.
SUBSTANCE: vortex spillway includes a flow swirling device and a discharge water conduit. The output portal of the spillway with discharge of the swirled flow into atmosphere is equipped with a jet-directing deflector made in the form of a slant or figured cut of the output section of the discharge water conduit. The fan shape of the free jet during discharge of the swirled flow into atmosphere aids its efficient aeration and spraying in air, and also larger length of the line of coupling of the discharged jet with the bottom of the lower reach.
EFFECT: prevention of formation of substantial plunge basins, higher reliability and safety of spillway and water-retaining structures.
