An anchorfor consolidating non-cohesive rock layers or for connecting them to solid rockprimarily has the necessary components for realising a stressed or expansion anchor. Furthermore, when a conventional domed plateis used, which reliably transmits the necessary stress forces, it is possible additionally to bond the anchor barin the drill holeafter stressing. To this end, the anchor baris either constructed with a connecting tubewith distributor heador the sheathing tubecomprises a top tube, these both fulfilling the task of conveying the grout bonding materialreliably from the drill hole mouth end of the anchor barto the rock endA and then diverting it there and returning it to the drill hole mouth, so ensuring complete fixing and sheathing of the anchor barin the drill hole
