Abstract

The injection bore anchor (1) has a steel tube (2) with a smooth outer surface section (6) and a thread (4,5) at one end. The first threaded section has a bore drive (BA) and an exchangeable adaptor (65) to feed an injection medium (M) and the other threaded section (5) with an outlet bore (30) for the injection medium and a flushing medium. There is a cross bore (7) in the middle of the tube, with an inflatable hose (12).
