Efficiency analysis of technologies applied in the course of selecting approaches to organization of constructionoperations and renovation of pipelines Анализ эффективности применяемых технологий при выборе подходов организации строительстваи ремонта трубопроводов
The authors consider particular methods, technologies and organizational aspects that may be implemented in the construction and renovation of pipelines using polythene materials instead of metals due to their economic and practical efficiency. It is noteworthy that the corrosion problem of steel pipelines is the phenomenon of metal destruction that reduces the throughput of pipelines and facilitates obstructions, juncture cleavages and water leaks as a result of reduction of service lives of pipelines. The authors analyzed the efficiency of polythene pipes from the viewpoint of hydraulic processes and the economic expediency; the authors identified that the polythene pipe’s throughput is 3 times as much as the one of steel pipes. Also, the authors determined the economic efficiency of polythene pipes: USD 0.5 million per 1 kilometer of pipeline.The authors take account of the technology-related aspect, as the water pipeline construction and reconstruction processes are limited by dense urban environments or due to the absence of overhaul factories in the close proximity to pipelines. Therefore, the results of the analysis evidence the efficiency of application of polythene in construction and reconstruction of pipeline engineering systems. It is highly resistant to abrasion and corrosion; it boosts the water flow velocity due to the low rough-ness of the internal surface; its service life is long enough, and its transportation is problem-free.
Строительство инженерных трубопроводных систем и ремонт их отдельных участков предусматривает разработку мероприятий, направленных на оптимизацию всех видов работ при реализации проектов. Эти мероприятия должны иметь практическое и экономическое обоснование с учетом их минимального воздействия на окружающую среду и человека.В основу предмета исследования легли актуальные методы, технологии и организационные подходы к реализации мероприятий по строительству и ремонту водопроводов с использованием полиэтилена в связи с экономической неоправданностью и практической неэффективностью использования металлов в процессе эксплуатации водопроводных труб.
