A method for sealing and repair of damaged pipelines laid underground and the existing systems, as well as a device for carrying out the method
The invention relates to a method of sealing and repairing damaged buried pipelines and/or drains and systems (lines) made up of these, suitable for use both during an interruption in the liquid flow through the pipeline and/or drains as well as during continuing liquid flows by successively placing at least two flowable, pourable, pumpable and, if need be, sprayable components at the leaky or damaged location(s), which react to form a mixture capable of hardening, the location(s) to be sealed being closed off in a section of the pipeline or drain by closure bodies. Furthermore, the invention relates to a device for carrying out the method.
