Abstract
The article presents the results of experimental studies to determine the throughput of the right-bank water intake structure and bottom galleries, the hydraulic regime in the galleries, and the movement of bottom sediments in them. Based on the results of the studies, a series of curves were obtained for the dependence of the discharge on the water horizon in the upper pool and the value of the opening of the gate of the intake structure. Checking the work of the galleries together with the working water intake holes showed that there is no mutual influence of them on each other. The total consumption of water passed through the water intake and galleries is practically equal to the sum of the consumption of water passed through these structures separately. It was found that the main amount of sediment accumulated in the headwater will fall into the left gallery, while slightly less (about one third) will fall into the right span, and only a small remainder leaves through the weir, while the water flow rate was distributed as follows: Qgal = 1.65Qwater.
Highlights
Large-scale measures are being taken in the Republic of Uzbekistan to improve the design of hydraulic structures, ensure their reliable and safe operation, improve the throughput and operating mode of spillway structures, and improve their effective mechanisms of work
The Strategy of Actions for the Further Development of the Republic of Uzbekistan for 2017-2021 outlines tasks, including "development of land reclamation and irrigation facilities to increase the competitiveness of the national economy." The solution of these tasks, during a period of shortage, including one important task is to conduct research work aimed at developing rational design methods and efficient operation, based on account of water resources of emerging damages, failures, and accidents, as well as stress-strain processes in the work of hydraulic structures of ground irrigation systems
We carried out hydraulic studies of the throughput capacity of the water intake structure of the Tuyamuyun hydroelectric complex [1-14]
Summary
Large-scale measures are being taken in the Republic of Uzbekistan to improve the design of hydraulic structures, ensure their reliable and safe operation, improve the throughput and operating mode of spillway structures, and improve their effective mechanisms of work. The Strategy of Actions for the Further Development of the Republic of Uzbekistan for 2017-2021 outlines tasks, including "development of land reclamation and irrigation facilities to increase the competitiveness of the national economy." The solution of these tasks, during a period of shortage, including one important task is to conduct research work aimed at developing rational design methods and efficient operation, based on account of water resources of emerging damages, failures, and accidents, as well as stress-strain processes in the work of hydraulic structures of ground irrigation systems In this regard, we carried out hydraulic studies of the throughput capacity of the water intake structure of the Tuyamuyun hydroelectric complex [1-14]. Water flow rates passing through the left-bank and right-bank water intakes are respectively equal to 500m3 / s and 120m3 / s
