ABSTRACT:
A device for destroying structures such as concrete walls comprises first and second plates each including at least a portion of explosive material which are mounted on respective sides of the structure to be exploded, preferably in alignment. Each pair of explosive plates is exploded substantially simultaneously or in short succession in order to destroy the wall portion therebetween. Because of the detonation of both of the explosive plates, the structure therebetween will be disintegrated without fragments being catapulted away in a hazardous manner. With the inventive method, the plates are positioned on respective opposite sides of the structure in opposing relationship and the plates are exploded so as to generate shock waves which extend inwardly toward the structure therebetween.
