ENGINEERING FEATURES OF NO-DIG REPAIR OF OUTDOOR UTILITIES

Abstract

Technological characteristics of the use of innovation methods for the no-dig repair of city infrastructure utilities, as well as prospects of the allocation of foreign technologies in Russia are considered in the work. The comparative analysis of technical and economic parameters of the pipeline section open-laying method with similar parameters of the most common no-dig repair technologies of gravity-flow discharge manifolds is reported with a specific example. The authors made conclusions on the need to carry out additional further research on both the development of new domestic polymer materials and manufacture of the assembly equipment, and the improvement of the regulatory system for the development of new standard technological documentation for the wide introduction of promising technologies of no-dig repair of outdoor utilities in the construction practice.
