Jacking pipes or tunnel casings
Jacking is a method that can be used to push a pipe or tunnel casing through an excavated hole. The procedure, commonly used in trenchless construction, involves forcing the component into a precut opening using technologies, such as mechanical, hydraulic or air jacks.
The method, also known as pipe jacking or pipe ramming, can also refer to the installation of pipes by hand excavation at the heading of the pipe that has been forced through the hole.
