Zusammenfassung:	Method for renewal and protection of sewage pipeline is performed through insertion of self-carrying insertion pipeline. To the pipeline being renewed one pulls polymer sleeve-lining, this has outer active (anchoring) surface. At that, one installs at one end of the sleeve-lining, from the outside, form-nozzle, with inserting to the inner part the end of the pneumatic coating-hose. After that one moves the form-nozzle and the pneumatic coating-hose to the other end of the sleeve-lining, with filling at that with concrete (fiber-concrete) mortar the circular gap formed behind the form-nozzle. The fresh filled concrete (fiber-concrete) mix is pressed through increasing pressure in pneumatic coating-hose, with taking out the pneumatic coating-hose after the concrete cures to strength.
