Diagnostics of materials and structures of heating system as a component of ecological management in a modern city

Abstract

Abstract. The maintenance of materials and structures of the underground space in modern cities which contains many engineering structures is considered in the article. It is claimed on the example of quantitative data that the underground structures exert a great influence on the ecological situation of the city. The matters of the research included the analysis of the main heating systems as the most responsible city structure; the conclusions obtained can be also used for smaller heat pipelines. The article includes the comparisons of modern technical methods of diagnostics of materials and heating systems structures according to the results of experiment, as well as the characteristic of norms of control of the materials condition at the stages of construction and maintenance applied in the developed countries. On this basis, the author has developed and presented a system of diagnostics taking into account the alternation of measures during the heating period as well as the season when heat supply is not required. For an effective ecological management in modern cities, it is suggested to create the automated data base of materials and structures of the heating systems on the basis of the developed scheme of their conditions and events, which needs to be used for forecasting of environmental risks and planning of recovery works with consideration of special features of the maintenance processes. The direction of the further research is defined: it is the expansion of the stated approaches on other types of underground communications in modern cities.

Technical-and-economic aspects of the analysis of the heating systems maintenance in the conditions of urban environment

“…Technical-and-economic aspects of the heating systems maintenance is based on the preliminary systematization of the conceptual framework, which is related with energy saving during the heating systems maintenance which needs to be treated as the integral component of the principle engineering procedure of the heat supplying entities, i.e. -transportation and distribution of heat among consumers [7]. In the conditions of Russia, Belarus, etc.…”

Formation of tools of resource providing management at the enterprise of the industry of construction materials in modern conditions

“…[3,4,20]. From our point of view, two indicators are the most interesting: gross value added (GVA) and industrial production index (IPI).…”

“…The reference points, which have key value for construction are provided in numerous documents and they are determined on the basis of the forecast of social and economic development till 2035, prepared by the Ministry of Economic Development according to which the economy of the Russian Federation, as well as other developed countries, will overcome crisis consequences the next 20 years. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] The exit of the Russian Federation from the recession in 2017 will be followed by slow growth: on average for 2% a year (from 1.7 to at most 2.6%). It is intended to increase GDP of the country for forecast 20 years only by 1.5 times.…”

Increase of the municipal land and property complex attractiveness on the basis of the development of cities infrastructure in Russia

“…Rational decisions are based on the methods of economic analysis, justification and optimization. The government bodies must constantly monitor the condition of the housing stock, communications and services provided [9]. Today, there is an urgent need to move from intuitive decisions of even very talented managers to rational decisions based on objective calculations.…”
