Itself ram boring apparatus, which can be driven, in particular for the production of rohrfoermigen earth boring

摘要

in a selbstantreibbaren rammbohrvorrichtung, particularly for the manufacture of tubular erdbohrungen, with a cylindrical housing of the vortriebsseite axially movable into and from a schlagkolben with rammschlagimpulsen beaufschlagbaren impact through the egg a source in vibrant, translational arbeitshu00fcbe antreibbar is proposedthat the rammbohrvorrichtung to drive the schlagkolbens (1), a rotary drive (2) with at least one of the antreibbaren kurvengetriebe (3) points, and that the schlagkolben (1) with a helixfu00f6rmigen fu00fchrungsnut (4). a helixfu00f6rmigen fu00fchrungsflu00e4che (5) as part of the kurvengetriebes (3) is trained.
