Course Description

Trenchless technologies include tools and techniques for condition assessment, rehabilitation, and installation of underground pipelines and utilities, and subsurface utility engineering. This course introduces subsurface utility engineering principles and techniques, and pipeline installation using horizontal directional drilling, pipe jacking, microtunnelling, and pipe bursting methods. Furthermore, trenchless rehabilitation of pipeline using various types of lining techniques are presented. In particular, material properties, lining technologies, and their benefits and limitations are discussed. Relevant case studies show the range of applications, advantages and limitations, and best practices for various trenchless techniques.
