Abstract


The article examines proposals for ensuring trouble-free and reliable operation of short-span spillway structures, which are widespread in reclamation systems of the Russian agro-industrial complex using the example of the Kursk complex hydroelectric complex. Is given an analysis of the results of hydraulic studies which evaluate the design solution for the devices of the outlet section of the three-span spillway of the hydraulic system that is expanding in terms of plan. Are presented the schemes of technical solutions proposed on the basis of experiments to find rational types of downstream devices that provide effective energy dissipation and prevent the formation of dangerous disruption currents. At the same time, the work of dampers and the entire outlet section was considered under various schemes of alternating open and closed spans of the spillway after its renovation.


Keywords


Downstream devices, Efficient energy dissipation, Flow failure.
