Experiences in adopting trenchless methods in China

Traditional methods of underground pipeline installation and replacement generally employ conventional open cut methods. These trenching methods in most urbanized settings typically create road closures, traffic delays, unnecessary detours, loss of access to homes and businesses, unsightliness, noise, and general disruption for everyone. Faced with population growth and an aging underground utility system, China has looked to emerging technologies to provide sustainable solutions to addressing this situation. Many challenges are present when promoting trenchless technologies in China including minimal local engineering knowledge, lack of trained contractors, lack of specifications, and system impact concerns raised by government owners. This paper provides a discussion of experiences in adopting trenchless technologies in China with recommendations obtained from lessons learned for individuals looking to initiate such future projects.
