Abstract

The present invention relates to a vibrationless rock-splitting apparatus comprising a structure consisting of an assembly of: a hollow supply pipe having a plurality of flow holes, both ends of which have coupling portions; a flexible tube arranged so as to cover an outer surface of the supply pipe, on the outer surface of which a plurality of equidistantly arranged spacing members integrally protrude; a fastening block which is threadedly fastened to the supply pipe such that the flexible tube having a plurality of support pieces at both ends thereof is tightly fixed to the fastening block by means of fixing means; and at least one or more guide tubes arranged on the outer surface of the flexible tube to prevent the flexible tube from being outwardly exposed, thereby expanding the flexible tube using water pressure and splitting rock in a vibrationless manner.
