FIELD: working measures on existing buildings, particularly wrecking of buildings, for instance oil product reservoirs.
SUBSTANCE: oil product reservoir comprises reinforced concrete panels reinforced with tightening wire layer connected to outer reservoir side and roof supported by girders fastened to inner columns. The columns are arranged along two circles spaced predetermined distance from central column. Sequence of demounting operations with the use of demounting crane is disclosed. Method involves setting lower demounting boundary; setting location points for demounting crane used for serial roof panels, vertical panels, inner columns and girders disconnection along with crane movement over reservoir bottom along a circle having predetermined radius and demounting central column. To demount central column rope is connected to upper column part and rope is pulled in column falling direction. After that hoist cable, which retains the column in place, is disconnected and column is tilted.
EFFECT: extended range of structures to be demounted along with reduced labor inputs and increased operational safety.
