Book excerpt: This Pipe Jacking publication is presented by the North American Society for Trenchless Technology (NASTT), a non-profit educational organization. The published work serves as a companion document to a portion of "NASTT's New Installations Good Practices Training Course" and is intended to provide contractors, engineers, and utility owners with an overview of the many benefits of this widely practiced trenchless method. Pipe jacking is defined as a cyclical process of simultaneously excavating the ground, removing the spoils, and advancing pipe segments to support the excavation. Pipe jacking is the mechanism to propel the pipe and machine in both open shield pipe jacking machines and microtunnel boring machines (MTBM). Advancing of pipe segments is achieved using a jacking frame fitted with high-capacity hydraulic jacks that push the pipe from the launch shaft. The jacking frame applies thrust to the jacking pipe and excavating face (shield or MTBM) simultaneously. The actual setup of a jacking frame can vary considerably, depending on the contractor's equipment and the size of the jacking shaft.All NASTT publications are peer reviewed by volunteer industry professionals to ensure that they offer generic and non-commercial information. This publication was funded solely by NASTT as part of our educational outreach programing. Since 1990, the all-volunteer members of NASTT have presented non-commercial information about green alternative engineering methods to North American communities and beyond. NASTT offers multiple, high quality trenchless courses each year throughout North America and at our annual NASTT No-Dig Show Conference and Exhibition.
