Innovation Technologies of Trenchless Replacement of Dangerous Pipelines

Summary

Innovation technologies and complete sets of equipment used at municipal water supply and sewerage networks for the trenchless replacement of emergency state pipelines of up to 600 mm diameter are presented. The technologies offered are notable for their principle novelty, high economic efficiency, do not demand earth works, the equipment and mechanisms are easy-to-manufacture. The use of up-to-date technologies makes it possible to abandon the construction of new communication means and service pipelines, to rehabilitate and improve completely the technical characteristics of operating networks after their reconstruction. Domestic developments possess higher technical and economic indices than their foreign analogous (output by 1,3 times, durability by 2–2,5 times). Technologies and mechanisms took out 57 patents including 7 foreign and 24 licenses were sold.
