Definitions

the present invention relates to a method for drilling rock and gravel soils, in which the cuttings are conveyed out of the borehole by means of compressed air, and to a flushing device for rock and gravel bores.
the present invention aims to provide a method which overcomes these disadvantages and the realization of a flushing device for rock and gravel bores, which allows large specific drilling to achieve performance, effortlessly drill larger drilling depths of a few 10 m, and which also allows larger grains, for example 20 mm in diameter, to be pneumatically extracted from the borehole.
the flushing device with which such a method can be carried out, is characterized by means for generating an air flow which is directed in the opposite direction to the drilling feed and which flows around the drilling rod at least approximately in an annular manner.
An attachment 1 for a rock or gravel hammer drill is provided at both ends with a screw nipple 3 or 4, which are welded into a jacket 9.
An annular nozzle 10 is formed on the jacket 9 and is fed via four feed bores 11 of a central compressed air bore 7.
the compressed air bore 7 passes through the two screw nipples 3 and 4 and the middle part 6 holding them.
the feed bores 11 are kinked and form a catch pocket 13.
the ring nozzle 10 which blows out against the drilling direction, has an inner nozzle jacket 14 with a part 15 that widens upwards.
the outer limitation of the ring nozzle 10 takes place by means of an outer nozzle jacket 17 at the end the narrowest area of this compressed air system is designed as a nozzle mouth 18. It runs m.a.W. the nozzle chamber 19 together against the nozzle mouth 18, so that the nozzle chamber 19 forms an actual pressure chamber.
a flushing device is provided in the attachment 1, e.g. placed on a hammer.
the central compressed air bore 7 supplies the sink hammer with the compressed air required for impact drilling, as is known per se.
catch pockets is extremely important, so that when the compressed air is turned off, not fine drill material, in particular when a vacuum is formed, flows into the nozzle mouth or the nozzle chamber 19. and through the feed bores 11 into the central compressed air bore 7, because this would expose the lowering hammer underneath to rapid wear. The risk of nozzle clogging would also be significantly increased.
a special attachment 1 is shown for existing plunge hammers.
the gap width of the ring nozzles 10 used can be chosen between 0.2 and 1 mm, preferably in the range from 0.3 to 0.6 mm. Power is supplied through at least four feed holes 1 with a 5 mm diameter. Since a nozzle chamber 19 with pressure build-up is provided, the only requirement is that the total through-section of the feed bores 11 is considerably larger than the outlet cross-section of the nozzle mouth 18.
the drill rods can be provided with several flushing inserts or inserts 1 for large drilling depths.
