This part of the paper focuses on individual areas of survey of trenchless technologies for renovation of pipeline systems. It underlines the relevance of the technology and maintains that the choice of any specific work method should be based on economic as well as environmental and technological criteria. It describes certain performance techniques and deals more closely with the pipeline replacement methods featuring hydraulic rod-type destroyer, pneumatic splitter, and rope winch. It is noted that the technologies in question help save material and labor resources and reduce economic costs through optimized timelines and earthwork scopes. Also, trenchless technologies, despite their technological constructability and environmental friendliness are shown to require further improvement in order to minimize adverse impacts on the lithosphere and atmosphere.
