{PDF} Pipeline design for installation by horizontal directional drilling Horizontal Directional Drilling Design Guideline Task Committee of the Technical Committee on Trenchless Installation of Pipelines of the Pipeline Division of ASCE

Prepared by the Horizontal Directional Drilling Design Guideline Task Committee of the Technical Committee on Trenchless Installation of Pipelines of the Pipeline Division of ASCE.
Pipeline Design for Installation by Horizontal Directional Drilling addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD). HDD is a trenchless excavation method that is accomplished in three phases and uses a specialized horizontal drilling rig with ancillary tools and equipment. This Manual covers topics related to HDD installation and is meant to be a guide for design engineers who have previous experience and knowledge of the HDD installation process and pipeline design methods. Topics include predesign surveys, drilled path design, pipe design, construction impact, and as-built documentation.
