Horizontal Directional Drilling Hdd

Download or read book Pipeline Design for Installation by Horizontal Directional Drilling written by American Society of Civil Engineers. HDD Design Guideline Task Committee and published by Amer Society of Civil Engineers. This book was released on 2005 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD). This Manual of Practice, which covers topics specifically related to HDD installation, was prepared by a committee of senior engineers who are leaders in the development of HDD techniques and practices. 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 is meant to be a guide for design engineers with previous experience and knowledge of the HDD installation process and pipeline design methods. Topics covered include: predesign surveys; drilled path design; pipe design; construction impact; and as-built documentation.
