What Does Pipe Jack Eye Mean?
A pipe jack eye is a sealing device located in the thrust pit and reception shaft to allow the cutter shield and product pipes to enter and exit the borehole without allowing lubricant slurry, soil or water to flow into the shaft.
Microtunneling and pipe jacking are trenchless construction techniques that allow for pipe installation beneath the ground surface without disturbing surface vehicular or pedestrian traffic. The operation can be carried out with two excavations at the entry and exit locations of the proposed pipeline.
