  • Architectural and planning organization of public areas of autonomous residential complexes of oil and gas industry

    The article deals with the issues of architectural and planning organization of public areas of residential complexes of the oil and gas industry. The classification of these zones by functional purpose, architectural and planning structure and design solution is proposed. The issues of energy efficiency and energy saving of public space of Autonomous settlements in conditions with low temperature indicators are considered.

  • "Overview of trenchless pipeline reconstruction technologies. Part 1. Non-destructive methods "

    The paper summarizes the most common trenchless technologies among the variety of pipeline reconstruction methods which are implemented without destroying old pipelines. It demonstrates the key benefits of the methods under review as well as their principal deficiency. The significance of these technologies, according to the author, is associated with environmental safety and economic efficiency they assure for construction works performed under unstable soil conditions as part of dense urban development. Special attention is given to such relining methods as Swagelining, Upex, Rolldawn, and U-Liners, and more light is shed on innovative technologies, such as GFK-liner (Germany) and Insituform (Great Britain). It is emphasized that the pipeline relining methods discussed in the paper, along with their undisputable strengths, have certain deficiencies, primarily related to a decreased throughput capacity of pipelines. This is why the need for use of nano and composite materials to line the inner space of a reconstructed pipeline should be made a priority.

  • Overview of trenchless pipeline reconstruction technologies. Part 2. Destructive methods

    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.
