Abstract (en)

[origin: WO2020064208A1] 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 curing compound for forming the anchor foot is injected by means of an injection member at least in a subregion of the bore and, after partial, not yet complete curing of the compound, a post-grouting medium is introduced under pressure via a post-grouting member into a region of the anchor foot, by means of which medium the not yet completely cured anchor foot is broken. According to the invention, there is provision that the post-grouting member has connected thereto an automatic post-grouting unit by means of which, at a freely determinable time, the post-grouting medium is introduced automatically into the post-grouting member in order to break the not yet cured anchor foot.
