The two most popular installation methods for Vitrified Clay (VCP) jacking pipe are the Pilot Tube Method (PTM) and Static Pipe Bursting, but VCP has also been used in Slurry Microtunneling and pipe lining projects. For more information on using VCP with one of these methods, please contact us.
All manufacturer’s recommendations for jacking force limits are based on “straight-line” drives, where the full jacking surface of one pipe is in contact with the full jacking surface of the previous pipe, subsequent pipe and push plate. Any deviation from line and/or grade will significantly reduce jacking surface contact area. This deviation may concentrate the applied load over a smaller area, which will result in a reduction of the jacking force capabilities of the pipe.
Specific questions, requirements or concerns should be discussed with the manufacturer prior to commencing any work.
