Mathematical justification constructive solutions project to modernize sewage treatment plants in the HPP

Abstract

The studies were carried out for wastewater treatment plants of the Zhigulevskaya HPP. The existing wastewater treatment plant is installed on a reinforced concrete foundation, which is made in the form of a reinforced concrete monolithic slab. The bottom of the foundation is located at an elevation of 6410 mm from the ground level. The main performance characteristics of existing local treatment facilit ies have been studied. A project for the modernization of treatment facilit ies is presented. Mathematical calculations in computer programs are presented to justify the modernization and implementation of the project of treatment facilit ies for hydroelectric power plants. In the annotation, you briefly describe the essence of the study. During the research, snow and wind loads were taken into account. The calculations of the bearing capacity of the frame, monolithic foundation slab and cantilever wall of the pit enclo sure are presented. For the I and II types of the limit ing strength, stability and safe use of the structure are ensured. The permanent and temporary loads of the monolithic foundation slab are estimated. Withdrawn graphics contour plots of stresses and displacements, according to which the precipitation condition is satisfied. The main results of the enclosing structure stage-by-stage calculation are presented.
