This book highlights recent advancements and innovations in trenchless technology via the adoption of combined micro-tunnelling and pipe-jacking techniques. This technique is more environmentally friendly, cost effective, less time-consuming and less disruptive compared to conventional open trench excavations for urban construction and urban infrastructure renewal projects. Pipe jacking is a non-destructive technique used in the installation of underground pipelines using a tunnel boring machine (TBM) and thrust forces derived from the hydraulic jack set-up in a deep jacking shaft. It is popular and commonly used worldwide for the installation of sewer and common services cable tunnels as well as for oil and gas pipelines.
