The rocks that form a natural geological reservoir for underground gas storage, during the operation of UGS, are exposed to prolonged cyclic loads caused by periodic injections and withdrawals of natural gas. At the same time, it is possible to develop and accumulate residual deformations in rocks that cause irreversible changes in the properties of rocks and this must be taken into account when designing and operating UGS.

This work analyzes the methods of dismantling and demolition of reinforced concrete structures, namely: manual, mechanical and semi-mechanical method, drilling and blasting method, thermal method. The main advantages and disadvantages of these methods, the possibility and economic feasibility of their use in the interests of the Ministry of Defense of the Russian Federation are also considered. On the basis of the analysis carried out, taking into account the limitations of the use of the methods, a promising electro-hydraulic pulse method for dismantling reinforced concrete structures was proposed and the necessary conditions for its implementation in industrial mastabs in the interests of the Ministry of Defense were indicated.

Keywords: reinforced concrete, reinforced concrete structures, dismantling, demolition, work safety, efficiency, military infrastructure

The types of Autonomous stationary energy-cooling systems designed for complete isolation of special objects operating without connection with the atmosphere are Considered. A technical solution is proposed that allows increasing the efficiency of the energy-cooling system, reducing the consumption of process water due to its partial recirculation for cooling the engine of an Autonomous power plant, as well as increasing the period of complete isolation of the object.

Keywords: energy-cooling system, underground facility, military infrastructure, complete isolation mode

This article discusses the possibility of managing environmental and economic risks of investment projects. Environmental efficiency is an important indicator in assessing the effectiveness of an investment project. It is revealed that when assessing the environmental efficiency of an investment project, it is necessary to use the established standards and agreements, normative legal acts in the field of environmental law. However, the legislation in the Russian Federation in the field of environmental risk assessment requires accurate calculations that will facilitate the task of the investor in the field of adoption of an effective investment project. It is analyzed that the final decision on the implementation of the project depends on the quality of the assessment.

The article presents theoretical studies of the effect of various plasticizers on the mechanical properties of epoxy compositions. Based on this, the method of plasticization of the epoxy polymer ED-22 was chosen using the introduction of modified epoxy resin UP-563, which differs from the previously used modified compositions for repairing automotive vehicles in the field the simplicity of the availability of modifications in the field and as providing the widest range of changes in the properties of the epoxy composition for USAGE field. The scientific novelty lies in the justification for the creation of a new repair composition consisting of ED-22 epoxy-diane resin modified by UP-563 laproxil for the repair of hull and capacitive parts of automotive equipment in the field, which has increased vibration resistance. frost resistance and impact resistance.
