DEVICE FOR DISINTEGRATION OF MATERIALS AND VOLUME STRUCTURES Russian patent published in 2000 - IPC

FIELD: mining art, applicable for disintegration of various materials: metals, artificial and natural mineral materials, polymeric materials, materials on composite base, as well as for destruction and cropping of volume structures made up of metals, concrete and reinforced-concrete materials, etc. SUBSTANCE: the device is made in the form of a flexible elongated cylinder, located with a margin on a reel (or placed in the form of hairpin curves, tacks, etc. in a transport bag; the flexible elongated cylinder has an external protective sheath, for example, of polyethylene reinforced by a caprone net, made in the form of a hemisphere with adhesive edges for attachment of the device to the surface of the material to be destructed (metal, structures, etc. ). The flexible cylinder cavity accommodates an explosive charge with a shaped recess. The explosive charge is made up of several components placed in elongated flexible hoses made in the form of a half-moon forming the shaped recess of the explosive charge by its cross-section, the impact of the explosive charge is concentrated on the metal (material) cutting line. Fastened in the partition between the hoses are: a stabilizer, initiator and discharge electrodes. EFFECT: essentially enhanced capacity of disintegration of thin-walled volume structures, considerably enhanced efficiency of the entire process. 2 cl, 5 dwg
