Standard Design and Construction Guidelines for Microtunneling Committee
Part of: Standard Design and Construction Guidelines for Microtunneling
Abstract: The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors: Internal operating, transient, and test pressures; Earth overburden (tunnel construction may result in significantly lower loads than those experienced with open-cut installations); Surface loads (i.e., surcharge, vehicle, railroad, and/or aircraft, when present); External static water head and vacuum (if present).
