Anchor with grout jacket |
摘要 |
An anchor 1 for consolidating non-cohesive rock layers or for connecting them to solid rock 2 primarily has the necessary components for realising a stressed or expansion anchor. Furthermore, when a conventional domed plate 10 is used, which reliably transmits the necessary stress forces, it is possible additionally to bond the anchor bar 4 in the drill hole 3 after stressing. To this end, the anchor bar 4 is either constructed with a connecting tube 22 with distributor head 24 or the sheathing tube 11 comprises a top tube 50, these both fulfilling the task of conveying the grout bonding material 12 reliably from the drill hole mouth end of the anchor bar 4 to the rock end 5A and then diverting it there and returning it to the drill hole mouth, so ensuring complete fixing and sheathing of the anchor bar 4 in the drill hole 3.
