A Technical and Economic Evaluation of Water Jet Assisted Tunnel Boring
A full size mechanical mole outfitted with a high pressure water jet system was used to bore a section of tunnel in granite. Data collected in the laboratory and in the field are included in the report. Section 2 presents the equations pertaining to the hydraulic system. Section 3 details the relationships describing the hydraulic cutting of rock. Section 4 discusses the laboratory work done to evaluate the interaction between mechanical and water jet cutting systems. Section 5 presents a discussion of the field boring results obtained at Skykomish. In Section 6 a technical and economic evaluation of a hypothetical 20 foot diameter jet assisted machine boring Skykomish granite is presented. Finally, Section 7 contains the recommendations of work needed for the practical implementation of jet assisted tunnel boring.
