DEVICE FOR PROTECTING SPACES THAT ARE OBJECTS OF NATURAL AND MAN-MADE FORMATIONS AND THE METHOD OF ERECTING IT Russian patent published in 2018 - IPC E21F15/00 E02B3/00 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in the mining industry, transport and hydraulic engineering systems, for protection of above-ground and underground spaces that are objects of natural and man-made formations, in the event of the elimination of landslides and depressions, and can also be used to create objects in other terrestrial and extraterrestrial spaces. Device includes a shell with a fast-hardening expanding substance and an explosive. In this case the shell is made of one or more vertical and/or horizontal multi-sectional system of shells, each of which contains a central shell, one or more subsequent shells located behind the central shell, with an explosive and rapidly solidifying expanding substance in the central shell, and in subsequent shells fast-hardening expanding substances, the central and subsequent casings are made of a composite nanomaterial possessing a shape memory system, along the perimeter of the following shells, there are harmonica-like slots made with the possibility of their rupture, and as fast-hardening expanding substance, a composite nanomaterial having a shape memory system is used.

EFFECT: elimination of voids in the Earth's crust, strengthening of soil masses.
