Constructive decisions

The calculation of metal structures was performed in the SCAD program, version 11.1, the calculation of the bases was performed according to the formulas of SNiP. Responsibility class of structures P (normal) in accordance with GOST 27751-88. For the relative mark of 0.000, the mark of the finished floor of the MAZK building was taken, corresponding to the absolute mark of +11.600. The foundations were designed on the basis of the conclusion of engineering and geological surveys. Groundwater at the site is recorded at an absolute level of 9.60 m. During periods of active snowmelt and precipitation, the maximum level of groundwater can be expected at depths of about 0,50-0,80 m. In terms of chemical composition, groundwater is aggressive to W4 concrete in terms of water impermeability and has low corrosive aggressiveness with respect to lead and high corrosiveness with respect to aluminum cable sheaths. For an approximate calculation of water inflows into the pits, it is recommended to take the following filtration coefficients: for bulk soils (IGE-1) - 0,05-0,7 m / day; for silty sands (IGE-2) - 1,0 m / day. Under the foundations of the MAZK, a sand cushion 500 mm thick is arranged under the remaining foundations 300 mm thick. Sand pad should be made of medium-grained sand with controlled compaction to usk. = 1,65 t/m. The width of the sand cushion at the level of the base of the foundation should be 0,3 m greater than the width of the foundation. The normative depth of seasonal freezing is 1,45 m. Underground reservoirs, process tanks are located on monolithic reinforced concrete slabs of concrete class B20, W6; F50, preventing the possibility of equipment floating at the maximum rise in groundwater. Foundations for equipment, advertising and road signs - monolithic, shallow reinforced concrete. Concrete class accepted B20, W6; F50. Foundations for fuel tanks - a monolithic reinforced concrete slab 400 mm thick made of B20 class concrete; W6; F50.
