Aleinikova A. Methodological principles of organizational and technological monitoring of sustainable operation of the sewerage networks and structures complex.

The constructive decisions and the basic requirements shown to sewer networks and constructions are investigated. The analysis of a modern condition of a complex of sewer networks and constructions of Kharkov is executed and the basic reasons of destruction of a complex of sewer networks and constructions are investigated. A study of the corrosion process as the main factor in the destruction of the complex of sewer networks and structures. The environmental risk assessment for the environment and human health has been performed, namely the conceptual scheme for determining environmental risks, the scheme of risk-assessment algorithm for environmental friendliness of man-made objects, the scheme of algorithmic support for analysis of environmental risks of sewerage facilities. It is proved that in the future the operation of the complex of sewerage networks and structures will increase the load on the environment and people. The forecasting of emergencies on sewerage networks on the basis of multifactor regression analysis is performed. It is determined that the activity of sewer tunnel mines in the future will increase the load on NPS facilities. A new method of cleaning sewers from different degrees of debris has been developed; organizational and technological recommendations for the repair of the sewer tunnel by pushing and introducing secondary treatment of reinforced concrete rings lined with ribbed polyethylene; technologies for restoration of fire extinguishing chambers using granite slabs and polymer cladding. A system of organizational and technological monitoring of the stability of the complex of sewerage networks and structures based on indicative assessments has been developed. Using a fuzzy logic device based on the MATLAB program, software tools have been created to determine a generalized indicator of the sustainability of the complex of sewerage networks and structures, with which it is possible to make decisions on the implementation of certain measures to adjust performance.
