WATER DISCHARGE CHANNEL OF POLYGONAL PROFILE WITH FLEXIBLE ATTACHMENT Russian patent published in 2014 - IPC E02B5/00 E02B8/06 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering. A water discharge channel includes two composite parts with symmetrical pairs of slopes, an upper one with slope gradient m₁ and a bottom one with slope gradients m₂, and a triangular base. On a vertex of a triangular base there laid in one longitudinal row are reinforced-concrete anchor beams 1, on the left and on the right to which gabion mattresses 2 laid across the bed along the line of bottom slopes m₂ are attached. Gabion mattresses are made of light fascines and perforated tubes laid into mesh wire layer by layer. Flexible mattresses 3 made of light fascines wrapped into a geogrid of tubular shape are laid along the line of side slopes m₁ in tight rows. Gabion 2 and flexible 3 mattresses are connected to each other by means of mesh wire and attached in some places to slopes of the channel by means of reinforcement bars 4. The channel of the polygonal profile of the proposed structure is converted to a reliable water discharge or conjugation structure intended for safe passage or discharge of maximum possible water consumptions. It can be used effectively as much as possible as a part of low-pressure dam and dam-free hydraulic assemblies, as well as the main irrigating network in piedmont and mountainous difficult-to-access sections.

EFFECT: improving efficiency and reliability of channel operation.
