DEVICE FOR DAMPENING OF ENERGY OF WATER FLOW Russian patent published in 2000 - IPC

FIELD: hydraulic engineering, in particular, energy-dampening devices of spillway structures. SUBSTANCE: device has toe basin expanding in plan with vertical walls and a lip. The toe basin is positioned between the feeding water conduit with vertical walls and the diversion canal, it is square-shaped in plan and provided with vertical end walls at the inlet and longitudinal walls, being an extension of the feeding water conduit. The lip in plan is made in the form of a curve, symmetrical relative to the toe basin longitudinal axis, facing with the camber the diversion canal; the curve consists of two arcs. Installed in the upper part of the lip is a floor over its curvilinear part. EFFECT: reduced danger of destruction of the canal bed and simplified design of the toe basin due to improved conditions of flow from the toe basin to the diversion canal. 3 dwg
