ment to ongoing education opportunities for everyone on the
team. The business took off from there. "
Planning the parallel bore
With so many trenchless methods at his disposal, Knott's task is
to determine the most effective way to complete a job. For this
parallel drainage-line highway-crossing, he narrowed his options
to two: a pilot tube system or the OTS system.
" The bores were shallow, going from one ditch to another, "
Knott explained. " The soil under the road was silty sand, so we
had some concerns about what potential voids using a pilot tube
system with drilling fluid may cause.
" Also, using a pilot tube system would have almost doubled the
amount of time on the job, and we would have had to add a couple
of additional workers pulling rods on the exit side. Those extras
can impact the cost-per-foot of a job. "
Wojtkiewicz added that another advantage of the OTS System,
when working in sandy soils over a pilot tube system, is its ability
to recess the cutting head into the OTS head to avoid overcutting
the loose material and creating a void ahead of the casing.
" Luckily, the ground material stayed consistent on these bores,
and we didn't have to do that. But it's nice to know that option is
available in ground conditions like the one on this project, " he said.
After choosing the best installation method for the project, the
team at BTrenchless set the stage to compare the two different
types of steel casing products.
For the first bore, the crew welded and installed 5/8-inch
Trinity spiral weld steel casing in 20-foot sections at a time. On
the second, BTrenchless used the Tri-Loc weldless interlock casing
system, a new product from Trinity.
" The Tri-Loc system has a bevel outer edge that helps with
alignment. Sections of pipe are secured using three rows of
interlocking teeth, " explained Tony Baker, business development
manager for Trinity Products. " On auger boring jobs, that usually
