摘要
FIELD: technology for controlling large-dimensional objects.;SUBSTANCE: in accordance to method, volumetric moisture of concrete is measured in zone of placement of controlled object, open parts of pipes and elements of fire ladder and borders are scanned in their fastening zone for determining zones of concentration of mechanical strains, estimated further is degree of corrosion of open sections of pipes or ladder elements and borders in their fastening area by means of geophysical complex, thicknesses of open walls of pipes or ladder elements and borders are determined in area of fastening, ultrasound flaw detection is performed over welded connections and parts of pipes of communications or section of fire ladders and borders are considered flawed on condition of detection on basis of results of diagnostic operations of degree of corrosion, equal to or exceeding 20 percents of loss of thickness of pipe wall or profile from original one, or loss of thickness of pipe wall or its casing in opening area exceeding 0,4 mm compared to section of pipe having no corrosion damage, or profile of ladder and border compared to section of profile, not having any corrosion damage, or in case of moisture level of concrete of inter-floor bridging or a wall, exceeding 2,5 weight percents or 70 specific units for GANN devices with electrode of 50V or on detection of defects in welded connections of pipes or in pipes.;EFFECT: increased information capacity and precision of diagnostics.;2 cl, 5 dwg
