Available in PDF, EPUB and Kindle. Book excerpt: This Standard Guideline covers the planning, design, pipe materials, and construction of microtunneling. Microtunneling is defined as a trenchless construction method for installing pipelines. The North American definition of microtunneling describes a method and does not impose size limitations on that method. The tunnel may be considered a microtunnel if all of the following features apply to construction: the microtunneling boring machine is remote controlled, a laser guidance system is employed, a jacking system is used for thrust, and continuous pressure is provided to the face of the excavation to balance groundwater and earth pressures. This Standard Guideline is a vital reference for owners, engineers, contractors, and construction managers.
