The article represents an overview and analysis of trenchless technologies used to provide for the leak resistance and strength of dilapidated sections of pipelines made of ceramics, cast iron, asbestos cement and other materials. Sectional pipeline repair technologies, considered by the authors, include those for the repair of loose joints of straight sections of pipelines and loose joints in the points of connection to secondary pipelines. Technologies analyzed by the authors also include those applied for the restoration of pipe shell cracks. Organic resins and bandages are to be used as repair materials.Besides, the authors provide detailed descriptions of the composition and properties of pumping resins injected into pipe cracks to restore the structural strength of pipelines and to assure their further reliable operation.Moreover, the authors assess the basic strengths of the bandage technology, including its low cost, low time consumption, and suitability to various types of pipeline damages (depressurization of joints, cracks, leaks, etc.). Besides, this method does not require any excavations, trenches, hoists or other machines.In particular, sections of underground pipelines, having diameters of 150 – 180 mm, may be repaired by specialized repair robots. Robots may be equipped with special-purpose devices, including cutter heads, bandage application heads, and color motion cameras. Besides, sectional repair of pipelines, having the diameter of up to 600 mm, may be performed using robots produced by Hachler Umwelttechnik, which are particularly efficient if the repair work is needed to be performed in the points of pipeline branching.The choice of specific pipeline repair methods and substantiation of their application are mainly driven by (1) the post-cleaning condition of a pipeline, (2) the findings of the telediagnostics, (3) options for arrangement and use of specialized machinery on location, and (4) feasibility of the pipeline operation in the course of repair works and procedures.
