Definition - What does Pipe Jacking mean?

Pipe jacking is a method of laying new pipes by assembling specially designed pipes on site and using a hydraulic jack to push the pipes into place. In contemporary technology, there are not many limitations besides the traditional engineering and economic concerns. It provides a pipe as structurally sound, flexible and as watertight as conventionally installed pipes.

Pipe jacking can also be referred to as pipe ramming.

Trenchlesspedia explains Pipe Jacking

Pipe jacking allows the performance of trenchless construction methods to install pipes over several hundred meters in a straight line, with a bend or with multiple bends and can be especially useful for microtunneling. Still, thrust and reception pits need to be dug or the project can utilize existing manholes. A pipe jacking project may employ several jacks, a shield at the front of the pipe string, and a thrust wall to provide a base to jack against.
