METHOD FOR DEMOLITION OF BUILDINGS AND STRUCTURES IN RESTRICTED CONDITIONS WITH COVERAGE Russian patent published in 2010 - IPC F42D5/05 E04G23/08 

Abstract RU 2379624 C1

FIELD: blasting.

SUBSTANCE: invention is related to the field of special blasting operations, in particular to demolition of buildings and structures in restricted conditions of settlements, when it is necessary to exclude emission of fragments and to minimise impact of air shock wave. Method of demolition with coverage, including drilling of blast holes as per specified grid, their charging, arrangement of double-layer gas permeable coverage out of worn car tyres and metal mesh and object blasting. Above exploded section of wall there are anchors installed, bearing joint is suspended onto them, and coverage is suspended to it after installation of blast net. Worn car tyres are placed above blast holes in one or two layers, binding them to each other. Metal net is suspended over tyres, stretching it at the bottom by means of weighting agent. To reduce intensity of air shock wave, foam plastic is installed inside tyres with a thickness of at least 70 mm.

EFFECT: invention makes it possible to exclude emission of fragments and to reduce intensity of air impact wave.
