Abstract: The invention relates to a method and a device for producing an injection anchor in the ground, wherein a bore is created in the ground, a hardening material for forming the anchor foot is injected by means of an injection member at least in a partial region of the bore, and after partial, not yet complete, hardening of the material a post-grouting medium is introduced under pressure in a region of the anchor foot via a post-grouting member, by which medium the not yet completely hardened anchor foot is broken up. According to the invention, provision is made for an automatic post-grouting machine to be connected to the post-grouting member, by which machine the post-grouting medium for breaking up the not yet hardened anchor foot is automatically introduced into the post-grouting member at a freely specifiable time.
