Description

Изобретение относитс к строительству, а именно к конструкци м водосбросов.The invention relates to the construction, namely to the structures of the spillways.

Целью изобретени вл етс повышение эффективности гашени энергии падающей струи с одновременным уменьшением динамической нагрузки на водобой.The aim of the invention is to increase the efficiency of damping the energy of the falling jet with a simultaneous decrease in the dynamic load on the waterwall.

На фиг. 1 показан водосброс, продольный разрез; на фиг. 2 - то же, вид сверху; на фиг. 3 - разрез А-А на фиг. 1; на фиг. 4 - струеотражатель, поперечный разрез; на фиг. 5 - водосброс с трамплинами , продольный разрез; на фиг. 6 - то же, вид сверху.FIG. 1 shows the spillway, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 - jet deflector, cross section; in fig. 5 - spillway with springboards, longitudinal section; in fig. 6 - the same, top view.

Водосброс содержит водослив 1, между бычками 2 которого устроены углубление 3 к консоли 4 (фиг. 1 и 2) либо трамплины 5 (фиг. 5), которыми поток раздел етс на струн 6, падающие р дами на струе- отражачелй 7 с гребнем при верщине 8. Боковые поверхкости 9 струеотражателей направл ют их в камеры, где они соудар ютс . Струеотражателн примыкают к водобойному порогу 10.The spillway contains a weir 1, between the bulls 2 of which are arranged a recess 3 to the cantilever 4 (Fig. 1 and 2) or springboards 5 (Fig. 5), by which the stream is divided into strings 6, falling in rows on a stream-reflecting 7 with a ridge at 8. The side surfaces 9 of the jet reflectors direct them to the chambers where they strike. Jet reflectors abut water penetration threshold 10.

Обратный уклон струеотражателей и камер гашени , а также угол при верщине призм в 90° способствуют максимальной эффективности гашени энергии потока.The reverse slope of the jet reflectors and blanking chambers, as well as the angle when prisms are 90 °, help maximize the efficiency of damping the flow energy.

Claims

Invention Formula

I. A spillway containing a weir divided by bulls into spans, a stream of prismatic elements, the crests of which are arranged by a jet coaxially flowing out of the weir and at a distance from each other equal to twice the span of the spill between the jetting elements of the chamber for counter-extinguishing faces of prisms of streams and a pipe threshold, characterized by the fact that: in order to increase the efficiency of damping of the energy of the falling jet with a simultaneous decrease in the dynamic load on the pg such, the weir is made in The alternating dimples and springboards, each of which have a discharge in two rows, transversely relative to each other gel across the width of the span, and the struc- ture-reflecting elements are installed under each of the outflowing streams, as The latter, two rows, are shifted in the transverse direction by the width of the span, and providing an adjoining to each jet-reflecting element of one of the chambers for counter-extinguishing of the jets of the other row.
