Abstract

1,208,365. Fluid-pressure blasting devices. MASCHINENFABRIK GLUCKAUF GUNTHER KLERNER. 25 April, 1968 [8 May, 1967], No. 19705/68. Heading F3A. Compressed air injection apparatus for splitting rock comprises an inlet tube 1; a head 2 having an outlet port 4 and a disc 3 which ruptures at a predetermined air pressure; and two sleeves 8 which define an expansion chamber 5 with the wall of the borehole, the sleeves being axially loadable in opposite directions and being capable of being stressed tightly to seal the expansion chamber by the action of compressed air escaping when the disc 3 has been ruptured. The innermost sleeve is radially stressed to a greater extent than the outer sleeve. The sleeves are maintained between fixed rings 9 and movable rings 10. A bush 11 having openings 12 spaces the rings 10 apart. The sleeves 8 can be mechanically stressed by rotating the tube 1 relative to the head 2. In another embodiment (Fig. 2, not shown) modified sleeves and maintaining rings are provided.
