    Mar 01, 2020 The essential element that distinguishes pipe jacking (as compared to other tunneling methods) is that the lining of the resulting tunnel is pushed through the ground from the starting point rather than being built section-by-section just behind the excavation face or within the tail shield of a tunnel boring machine. Pipe jacking has been
