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 in economic incentives to the user. Because the operating 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 be shared 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's book of definitions wrote, "A Hole .. .Is to Dig." But this statement is not necessarily true. Today, a hole could be to bore.

This is the first broad-based guide to the increasingly important subject of trenchless technology - the wide array of processes and techniques for digging holes and rehabilitating conduits without disturbing the ground surface. Trenchless technology has become an effective and economic alternative to open-cut construction. Cities and communities can no longer afford to disrupt traffic or disturb the public. Nor can they afford the high costs of restoration that result from traditional methods. An Introduction to Trenchless Technology provides you with a sound understanding of what this technology is, how it works, and what benefits it offers. This first-of-its-kind resource gathers information on the latest techniques and equipment used in guided boring, pipe jacking, microtunnelling, auger boring, horizontal directional drilling, on-line replacement, and renovation. Clear guidelines not only help you decide how and where to apply trenchless methods, but also demonstrate the strong economic advantages they offer. The book's unique classification system and easy-to-understand descriptions explain each method in detail. Also, a special chapter on job planning shows you critical factors to evaluate when using the technology. Throughout the book, case histories offer valuable insights on how trenchless technologies actually work
