Environmental safety and natural resources| Резюме: | All methods of combating the flooding of populated areas are directly related to the execution of significant volumes of earthworks, the construction of special structures, and therefore require comprehensive analysis and substantiation and the selection of the most economically feasible and affordable project options during design.But analyzing the main methods of protecting the territory of settlements from flooding, it should be noted that even with their optimal use, the problem of flooding territories due to river tributaries remains. Therefore, it is worth focusing attention on the search for a technical solution that would make it possible to pump water from the tributary to the river without using expensive, complex in design and energy-consuming equipment. One of the promising solutions is the use of automatic gateways.The purpose of the work is to study the hydrodynamic parameters of the proposed design of the self-acting lock to prevent flood spills.The design of a hydrotechnical structure (self-acting sluice to prevent flood spills) is proposed, which is designed to prevent flooding of territories due to river spills and can be used to regulate the water level in hydraulic systems. It is shown that the use of the developed structure will make it possible to significantly reduce the negative consequences of possible flood spills in the territories.A three-dimensional model of the self-acting sluice was developed in the SolidWorks program to confirm its performance and study the hydrodynamic parameters of the self-acting sluice. The simulated simulation of the proposed design of the ejector pump in the FlowSimulation software module confirmed its efficiency and made it possible to determine the distribution of pressures and fluid movement speeds in it. It was established that the flow rate of the liquid flowing through the cross-section of the pipeline for water intake from the tributary is 0.055 m3/s at a river flow speed of 3 m/s. |
