METHOD FOR DISMANTLING OF FOUNDATIONS IN TIGHT CONDITIONS BY EXPLOSION ENERGY Russian patent published in 2009 - IPC E02D37/00 F42D3/00 

FIELD: construction.

SUBSTANCE: invention is related to construction, namely to methods for dismantling of foundations by explosion energy in tight conditions. Method for dismantling of foundations by explosion energy in tight conditions consists in the fact that boreholes are drilled in base of foundation, they are charged with necessary mass of explosion energy, free space is filled by tamping, and heavy metal shelter is installed above dismantled foundation. Installation of shelter is carried out with creation of tight air gap, ratio of which to shelter weight amounts to 1-10 m³/t. Opposite borehole charges, tanks are installed, which are filled water or aqueous solution of inhibitors of gas-air or dust-air medium ignition, which prevent inflammation of explosive medium with simultaneous degassing of toxic products of explosion.

EFFECT: provision of possibility to perform dismantling of foundations in close proximity from existing production facilities with complete observation of safety engineering and sanitary norms at gas-dangerous enterprises, acceleration and cheapening of blast works, improved quality of dismantling of foundations of any size at full elimination of actions from damaging factors of explosion.
