Abstract (en)
[origin: WO9115656A1] An injection bore anchor for securing sections and spaces by injection, for example of plastic, in particular in mining and tunnel construction, consists essentially of an anchor tube composed of at least two sections which can be connected to each other by muffs. The anchor tube has at least one injection port in the region of the tip of the anchor and a detachable connection element at the end projecting from the borehole. To introduce this injection bore anchor without using a flushing medium such as air or water, a screw conveyor (7) is welded onto at least one section (2) and one section (3) has a swelling packer (8) and a nonreturn valve (17).
