Formulation of the problem. Ensuring reliable operation of wastewater systems is one of the important tasks of community services Ukrainian cities. Sewer pipelines and collectors in Ukrainian cities have different operation life. In some cases, the operation life of wastewater working systems is more than 100 years. Significant operating costs, maintenance and inspection of sewer networks are made to keep them in reliable condition. Sewer pipes, sewers and inspection of the mine are operated at highly aggressive conditions. The concentrations of carbon dioxide, ammonia, methane, hydrogen sulfide and other corrosive substances greater than the maximum allowable concentration in the gas environment of collectors and inspection shafts. This leads to corrosion of concrete nutrient. The problem of preservation and revitalization of existing collectors is relevant because to environmental requirements increase. An important environmental challenge is the protection of groundwater against aggressive reagents, which can get into the groundwater through a rotten constructions of wastewater systems. Purpose. Consolidation of experience survey dredging well collector in Kharkiv, an improvement of technical solutions and recommendations of ensure their continued reliable and safe operation with development, which provide resistance to dredging well construction of biogenic corrosion. Conclusion. Technology and recommendations were designed to bring construction of dredging well to normal technical condition. The aggression of the environment has been taken into account. The decisions will ensure the normal operation of dredging well for 20 years. At work was used modern corrosion-resistant materials: concrete of sulfate-resistant cement, glass-plastic composite reinforcement.

Formulation of the problem. This article contains information about the methods and the planning principles used in experimental research study of the injection technology of impervious screen. Today, there are ways to create impervious screens and curtains solve soil protection issues in the field impermeable layer arrangement at a shallow depth. However, for Ukraine, in the burial sites of radiation and other wastes is urgent issue of protection of underground space in places with deep impermeable layer. Classical methods can not fully solve such problems. To solve them, you need to develop innovative technology to create such a screen, which will lie authentic sole object to be protected, at the project depth. For the experiments, it is necessary to choose the most important indicator, and technological factors affecting it. This is due to the fact that the proposed technology provides for lesser known technical solutions, the use of which should ultimately result in impervious screens with desired properties. Goal. The aim of this study is the selection of technological parameters of injection, design of experiments and the selection of indicators characterizing the efficient operation of the screen. Such constructs must first have almost zero permeability. In this paper, it was of interest to study the influence of process parameters on the filtration rate of the protective screen. Conclusion. As a result of the design of experiments, the basic technological factors that have a significant effect on the studied parameters. varying levels of these factors are also identified, which in turn makes it possible to determine the optimum process parameters creating a screen that meets all the desired properties and characteristics. Based on a series of experiments it is possible to obtain optimal formulations for different types of soils.

Formulation of the problem. The deficit of grain storage capacities in Ukraine is about 15-20 mln. tons. Specific conditions of the realization of grain storage construction projects require systemic research to improve the efficiency of organizational and technological solutions in the management of specialized companies, to reduce costs of construction works and to increase the profit margin. Purpose. Research changes in the structure and the amount of the total production costs of the grain storage construction enterprise under the influence of organizational and technological factors. Conclusion. The account of features of grain storage construction, as well as developed research methodology: have resulted in analysis and the construction of a computer model of the operating activity of the grain storage construction enterprise; have allowed exploring experimental and statistical regularities of indicators changes of such operating activity from the influence of organizational and technological factors.

Formulation of the problem. The institutions which are engaged in education of young athletes of Ukraine are going through a rough patch. Today there are boarding schools with a sports bias, but they are not enought, and resource base and conditions of staying in them need improvement and reorganization. In turn, foreign experience of design of sports institutions for children and adults deserves special attention as it includes the best world technology and architectural concepts and receptions. Article purpose: to analyze foreign experience of design of sports facilities, and also to reveal the main directions of their organization. To develop the conceptual project offer of sports boarding schools in Ukraine. Conclusions. The main tendencies of development of sports facilities abroad have been revealed. Relying on foreign experience, the basic principles of their formation have been defined. Knowledge gained with the help of analysis is introduced in the project offer of a children's sports complex in the city of Dnipro and can become a basis for reconsideration and modernization of the developed network of sports facilities in Ukraine.
