UDK: 620.1:622.276
DOI: 10.24887/0028-2448-2019-8-141-144
Key words: constructions, building structures, reliability of structures, technical assessment, technological overpasses, oil refining facilities, oil refining and petrochemical industry
Authors: R.A. Sabirov (RN-BashNIPIneft LLC, RF, Ufa), P.V. Poteshkin (RN-BashNIPIneft LLC, RF, Ufa), А.N. Avrenyuk (RN-BashNIPIneft LLC, RF, Ufa), V.M. Yakimov (RN-BashNIPIneft LLC, RF, Ufa), S.S. Filipovich (RN-BashNIPIneft LLC, RF, Ufa)

The article describes the experience of checking the conclusions of the survey of the technical condition of facilities at hazardous production facilities of oil refining and petrochemical industry, performed by subcontractors. Considered in detail the individual moments, the joint account which would enable the authors of these opinions to avoid misconceptions, to improve the quality and completeness of the surveys: changing the requirements of standards for loads; as well as the geometrical characteristics of the rolling profiles of steel structures (including corrosion) for various time periods of construction and operation; it is noted that a mandatory part of the instrumental work during the survey of structures for further consideration of research results in verification calculations is the determination of the actual (residual) thickness of steel structure elements; determination of steel grades and the maximum permissible negative temperature of steel structures made of boiling steels, the use of which is currently prohibited; determination of the degree of neutralization (corrosion) of concrete in reinforced concrete structures and its impact on the state of reinforcement; determination of the state of supports and suspensions on pipelines and its impact on the construction of overpasses.

Issues and solutions for the examination of underground structures (shallow foundations, pile foundations) and the determination of the bearing capacity of pile foundations are addressed.

A comprehensive analysis of the technical condition of the structures will make it possible to make informed decisions on the further safe operation of the survey object, on the rationality of replacing old structures with new ones, or on the cost-effectiveness of the option to strengthen them, the possibility of additional loading of building structures during reconstruction or technical re-equipment, and also operation in monitoring mode.
