Abstract
Proposed is a concrete, stoneware or cast pipe with a pipe tip (1) and pipe bell (2) containing a peripheral test chamber (5) between a sliding ring seal (4) and hose seal (3) capable of being activated, from which a compressed material can be discharged to effect secondary sealing. The test chamber (5) can be connected to a test line (11). Also disclosed is a method of monitoring the leak-tightness and sealing of the pipe connections: a peripheral test chamber (5) is provided between pipe tip (1) and bell (2) and between two ring seals at least one of which is a hose seal (3) capable of being activated. The test chamber is pressurised to at least 0.2 bar via a test line (11) and the pressure loss is measured to reveal and locate leaks, the hose seal (3) then being activated. It is thus possible to detect, locate and seal leaks as soon as damage occurs.

INARTIKEL 19 GENANNTE ERKLÄRUNGARTICLE 19 EXPLANATORY STATEMENT
Erfindungsgemäß ist vorgesehen, daß beim Erkennen einer Leckage des Rohr¬ leitungssystems durch Beobachtung des Drucks in einem Prϋfraum (5) diese dadurch behoben wird, daß in eine Schlauchdichtung (3) ein Verpreßmaterial injiziert wird, das eine entstandene Undichtigkeit wieder verschließt.
According to the invention, when a leakage of the pipeline system is detected by observing the pressure in a test chamber (5), this is remedied by injecting into an inner tube seal (3) an injection material which reseals a resulting leak.
