Abstract
A tunneling system including a tunneling apparatus including a cutting structure for forming a borehole and at least one linkage section for transmitting a force generally toward the cutting structure is disclosed. A method of disposing a casing string within a subterranean formation by applying a force generally to the trailing end of the tunneling apparatus, generally toward the leading end thereof, but without transmitting the entire force through the entire casing string is also disclosed. At least one linkage section extending within but not in contact with at least one casing section of the casing string may transmit the force. Also, a force limiting member may limit a force applied to the casing string.
