Horizontal directional drilling poses its own special problems, not the least of which are those caused by trenchless excavation, a three-phase method, and specialized tools, rigs and equipment. This manual of practice includes such topics as predesign surveys, including subsurface investigation, drilled path issues such as penetration angles, depth of penetration, radius of curvature, complex installations and casings, pipe design including issues for steel and polyethylene pipe, construction impact, and preparation of as-built documentation. The authors include a glossary and references. Annotation ©2005 Book News, Inc., Portland, OR Tags: pipeline design for installation horizontal directional drilling |
