CCI has developed a Strain Measurement System that records the actual strain experienced by a pipe section as it is pulled into a borehole during the pullback operation in an HDD crossing. 

We first developed this tool as a one-of-a-kind application to verify the current industry design process (as recommended by Pipeline Research Council International) and investigate how to improve on the design process delivered to our clients. Direct research and analysis has allowed CCI to yield more cost effective projects for our clients.

We have completed eight runs of this tool on various size projects and collected a significant amount of valuable data. Ongoing analysis of this data has been conducted as part of a CCI research and development commitment. This analysis has led to new ways to design trenchless pipelines, pull back operations and construction that we are incorporating into our business. 

We expect that our Strain Measurement Tool will continue to improve all future operations making HDD construction much more cost effective and reliable.

Experimental Study on Pullback Loads for Steel Pipelines Installed by Horizontal Directional Drilling

The importance of site-specific factors are often neglected which has led to significant discrepancies between expected forces and observed values during construction. Pull force estimation during Horizontal Directional Drilling (HDD) is one of the essential steps during planning and design phases of bridge projects.
