METHOD FOR PROTECTION OF ENVIRONMENT Russian patent published in 2011 - IPC E04G23/08 

FIELD: ecology.

SUBSTANCE: method for environment protection includes damaging structural elements of a building by gripping of building elements with load gripper device, taking them out of building plane and their transportation to a specially dedicated site. Additionally foam generators are used, and before destruction of building structural elements starts, a row of vertical stands is installed along its perimetre, on various height of which brackets are fixed, and near stands mounting platforms are placed, onto which foam generators are installed, and between vertical stands ropes are pulled at various levels, corresponding in height with installed brackets, besides, ends of each rope are fixed to brackets corresponding to this level, afterwards vertical screens are fixed to ropes between vertical stands in the form of flexible cloths, besides, upper edges of screens are fixed to ropes of the highest level, lower edges of screens are lowered down to earth surface, and at the edges screens are fixed to brackets, then, by application of foam generators, space between vertical screens and the building are filled with foam, and only afterwards, using load gripper device, building structural elements are damaged, and on completion of works on damage of building structural elements, foam generators, mounting platforms, vertical screens and vertical stands with brackets are dismantled.

EFFECT: reduced pollution of atmospheric air and adjacent territory to dismantled building since production of significant dust amount in process of destruction of building structural elements is avoided.
