Analysis of damages and defects of the repair and operational unit of the compressor station
The need to maintain the technical condition of buildings with a significant service life determines the regularity of their inspection. The paper presents the analysis of the results of the inspection of the building of the repair and operational block of the compressor station. The analysis of the design documentation and the results of the measurement work showed that the construction is a one-story basementless building with dimensions of 54.62x18.74x5.9 m. The performed visual examination showed the presence of damages and defects of the third and fourth categories, which requires certain actions to eliminate them. Visual examination showed the need for instrumental examination. In particular, the need to determine the strength of brickwork and the strength of concrete in structures. The analysis of the results of the instrumental examination showed: the results of testing the wall masonry by the shock pulse method using the ONIKS 2.5 device showed that the compressive strength grade of silicate and ceramic bricks of the walls of the repair and maintenance block corresponds to M100, and the grade of masonry mortar is M50; The results of concrete testing by the non-destructive method of strength control in accordance with GOST 22690-88 with the DigiShmidt 2000 device showed that the class of concrete in terms of compressive strength in reinforced concrete slabs of the covering of the repair and operational block corresponds to B20, and the class of concrete in reinforced concrete beams of the covering corresponds to B25. The verification calculation showed that the strength of the reinforced concrete pavement of the repair and maintenance unit under the full design load acting at the time of the survey was ensured. The analysis showed that the technical condition of the maintenance and operation unit is of limited serviceability. The work provides recommendations for eliminating defects and damages.
