Embodiment Construction
[0086] The spillway, e.g. of a hydro power plant weir or similar hydrauic structure with the improved dissipation efficiency according to the invention is presented on the FIG. 1 in the longitudinal cross-section along the plane A-A according to FIGS. 11 and / or 12, and on FIG. 11 and 12 in the transversal section in the section B-B according to FIG. 1 or rest FIGS. 2 to 10. The spillway—when observed in the flow direction—in principle consists of overflow spillway 1, stilling basin 2 with the end sill 3 or without it, and is on sides constrained with the side walls 4′, 4″, that are running in the flow direction.
[0087] If needed or depending on the purpose of the spillway, the gate 6 or similar closing device may be positioned in the field of spillway area, that are quite schematically presented in FIGS. 1 to 10, but in a quite understandable manner for those skilled in the art. At the construction of the spillway, presented on FIG. 12, the sidewalls 4′, 4″ are flat and vertical, wh...
