Abstract
Purpose: analysis and construction of hierarchical and facet classifications of reclamation pumping stations (RPS). During the research, a search, analysis, comparison and systematization of RPS types were carried out in accordance with regulatory and technical documentation, as well as the developments of various Russian scientists. When developing and constructing RPS classifications, the following methods were used: facet and hierarchical. Discussion. As a result of the study and analysis of various sources of information, it was found that the existing RPS classifications in most cases are presented according to one classification criterion. In this regard, a classification has been carried out at several levels. First, the main classification criteria such as the purpose and main characteristics, including flow and pressure, were determined, according to which the hierarchical classification was built. Subsequently, lower order classification features were considered: importance classes, degree of durability, design, type of building, structure configuration, location relative to the irrigation source, location in the system, degree of use, type of water intake structure and source, devices used and control principle. Based on the indicated classification criteria, hierarchical and facet classifications of the RPS were formed. Conclusions. As a result of research, a hierarchical classification of the RPS by main types with a hierarchy of vague subordination up to the seventh level with minor groups of classification characteristics has been developed. The use of the facet method made it possible to combine all types and kinds of RPS into a more detailed classification with the introduction of some independent classification features of lower levels, specifying certain types of RPS within the hierarchical classification levels. The developed hierarchical and facet classifications of RPS make it possible to their further use in the development of a regulatory document on RPS design.
