ASSEMBLY OF FLOWS CONNECTION Russian patent published in 2019 - IPC E02B13/00 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering, and more specifically to structures for connecting the flow systems of the territory, construction sites of industrial and civil facilities located in difficult topographic and hydrological conditions. Device includes lead 1 and discharge 2 sections of receiving channel with side walls 3, 4 and bottom 5, associated ledge 7, which is below the bottom of one of the side walls of discharge section 2 of the receiving channel adjacent the output section of the final section of admitting flow passage 9. Ledge 7 is made in plan in the form of a curve, the ends of which are located tangentially to the corresponding side walls of the admitting flow passage and the receiving channel, with a concavity directed toward admitting flow passage 9. Bottom 6 of discharge section 2 of receiving channel outside the node connection flows is located below bottom 5 of end section 1 of receiving channel by an amount equal to the difference of the depths of flow on discharge 2 and end 1 sections of receiving channel, which are determined by the flow curves of end 1 and discharge 2 sections of receiving channel when skipping the maximum costs.

EFFECT: technical result consists in providing a connection of the flows of the receiving channel and the admitting flow passage with minimal losses and without wave formation, that provides the ability to perform the side walls of the receiving channel with a minimum height and minimal design changes.
