Zero Degree Horizontal Directional Drilling (HDD) is a method of installing underground pipelines through trenchless methods. It involves the use of a directional drilling machine, and associated attachments, to accurately drill along the chosen bore path and back ream as per pipe specification. It differs from the actual Horizontal Directional Drilling since not taking the curvature or angle. After a detailed study of the soil investigations and site condition of the obstacles like Road, Nala and Railway the following installation method has been formulated to provide a successful installation of Pipeline across the obstacles using Zero Degree HDD
