Large Pipe Jacked Half Mile In One Drive

September 2010 Vol. 65 No. 9
The pipes are being supplied by Hobas, and are the largest CCFRPM pipes made to date with an OD of 118 inches.

CCFRPM was not the least expensive piping material for the project but the higher material cost was outweighed by the savings. For example, a 30 percent reduction in soil extraction was possible due to the high-strength thin walled product, which creates a smaller OD for the same ID. Construction equipment could be kept small and to a minimum, which was crucial in this tight space. Fast onsite assembly, long life expectancy and low maintenance all factored into the cost analysis.

CCFRPM pipes have experienced success globally in long jacking runs.
