Modern Jacking Pipe Design and Liners: Optioneering for Longevity, Safety, and Sustainability

Abstract

Modern jacking pipe design has evolved to meet the increasing demands for cost efficiency, durability, and risk reduction in trenchless pipeline installations. A critical aspect of this evolution is the selection of appropriate liners, which play a key role in enhancing structural performance, corrosion resistance, and overall service life. This paper explores the benefits and trade-offs of various jacking pipe liners, including Glass Reinforced Plastic (GRP), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Cement Mortar Lined and Epoxy Lined Steel. Through a comparative analysis, the study examines the impact of these materials on life cycle costs, hydraulic performance, installation complexity, and long-term reliability. The concept of "optioneering" is introduced as a structured approach to evaluating liner selection based on projectspecific requirements, balancing technical, economic, and environmental considerations. By integrating modern materials and engineering best practices, this paper provides valuable insights into optimizing jacking pipe designs for improved performance, sustainability, longer drive lengths, curved alignments, fewer shafts while reducing installation risk.
