Book excerpt: The objective of this study is to assess horizontal drilling as an alternative to pilot tunneling in geological investigation prior to the design and construction of highway tunnels and to identify means to increase the penetration capability and accuracy and decrease the cost of horizontal drilling. Volume 1 assesses the horizontal penetration capabilities of available drilling equipment. Volume 2 presents a model for estimating the time and cost of drilling long horizontal holes. Sample problems are worked in detail to illustrate the application of the model to four (4) different drilling techniques. Volume 3 evaluates the potential for improving horizontal drilling capability by: (a) more efficient use of existing equipment, modification of existing equipment, and adaption of equipment not previously employed for horizontal drilling and by (b) developing new horizontal drilling equipment and techniques.

This book was released on 2012-12-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular.
