Description
Изобретение относитс к гидротех ническому строительству, в частност к каналам, транспортирующим наносонесущие потоки, например сели. Известно наносопровод щее сооружение , включающее канал с уменьшающимс уклоном дна и плавным сужение и расширением ul. Известно также наносопровод щее сооружение, включающее канал с умен шающимс уклоном дна С2. Недостаток известных устройств з ключаетс в том, что на нижнем учас ке канала происходит отложение наносов , привод щее к выходу сооружени из стро . Цель изобретени - повышение надежности сооружени . Цель достигаетс тем, что нижний участок канала с малым уклоном дна выполнен с переменно возрастающей по течению шероховатостью. . На фиг. 1 изображено наносопровод щее сооружение, продольный разрез; на фиг. 2 - то же, план. Сооружение включает призматический канал, состо щий из участка с большим уклоном дна 1 и участка с малым уклоном дна 2, который выполнен с переменно возрастающей по течению шероховатостью 3. Наносонесущий поток, поступа на участок с уклоном дна 2, движетс с меньшей скоростью, однако транспортирующа способность потока сохран етс благодар переменно возрастающей шероховатости 3, вызывающей образование в патоке дополнительных вихрей, вследствие которых градиент полной механической энергии вдоль потока увеличиваетс , что приводит к увеличению транспортирующей способности потока и обеспечивает бесперебойную работу сооружени .FIELD OF THE INVENTION The invention relates to hydraulic construction, in particular, to channels transporting sediment-carrying streams, such as mudflows. A nanoconductive structure is known, including a channel with a decreasing bottom slope and a smooth constriction and expansion ul. It is also known to be a nanoconductive structure, including a channel with a decreasing slope of the bottom C2. A disadvantage of the known devices is that sedimentation occurs at the lower part of the canal, leading to the exit of the building. The purpose of the invention is to increase the reliability of the structure. The goal is achieved by the fact that the lower section of the channel with a small slope of the bottom is made with varying upstream roughness. . FIG. Figure 1 shows the nanoconductive structure, a longitudinal section; in fig. 2 - the same plan. The structure includes a prismatic channel consisting of a section with a large slope of the bottom 1 and a section with a small slope of the bottom 2, which is made with a variable roughness along the flow 3. The deposited flow entering the section with a slope of the bottom 2 moves at a slower speed, however the flow ability is retained due to the continuously increasing roughness 3, which causes the formation of additional vortices in the molasses, due to which the gradient of the total mechanical energy increases along the flow, resulting in increase the conveying capacity of the flow and ensures smooth operation of installations.
