Summary: | A disposable tubular borehole plug for the injection particularly of media suitable for rock solidification, such as for example synthetic resin, comprises substantially a filling pipe (1) adapted to be assembled from portions and having at the tip a safeguard against reflux, in the form of a non-return valve (5), a mixing element and a sealing element (2) mounted at the ends in metal sleeves (11, 12) and formed as a portion of tubing of elastic material. The filling pipe (1), within the area enclosed by the sealing element (2), is additionally provided with a valve (8) and in that during injection, the sealing element (2) becomes automatically clamped and sealing-tight as a function of the differential pressure built up by the valves (5, 8). |
