Trenchless Employs Latest Auger Boring Tech
means aligning the next section of pipe in the pit with a crane or
excavator, and then advancing the auger boring machine until they
hear the 'popping' sound of the teeth locking together. It can all be
done in a fraction of the time of traditional welding methods. "
BTrenchless' objective in using the two different casings was
to compare how much faster the crew could complete the bore
using the Tri-Loc product compared to having to weld together
each section of pipe.
" The soil conditions were the same. We used the same auger
boring machine equipped with the same McLaughlin OTS head.
And the people on the crew were the same. So, it truly was a fair
comparison, " explained Knott.

Comparing productivity

On the first bore using the standard spiral weld pipe, the crew was
able to complete the bore in seven working days, averaging about
two hours of welding every time a new section of pipe was added.
Using the Tri-Loc product on the second bore, the same crew
was able to double the production per 10-hour shift, to finish it up
in a little over three days. The crew even tack welded each joint for
added peace-of-mind.
" We typically use a five-person crew on auger boring jobs, and
anytime a new section is being added to the pipe string, three of
them are waiting around for the welding to be completed, " said
Wojtkiewicz. " So, cutting that idle time by approximately 75
percent is huge for our customers and us. "

The team at BTrenchless prides itself on keeping up with all
the latest advances in trenchless technology. In fact, it first
learned about the McLaughlin OTS System at the Underground
Construction Technology (UCT) International Conference &
Exhibition a few years back, and more recently, the Tri-Loc product at a microtunneling training event.
" Before investing in the OTS System, our crews were making our
own steering heads that could be adjusted for grade, " said Knott.
" But we didn't have anything to check and adjust the line like the
OTS does. We rented the system a couple of times before investing
in our OTS control station and various sized steering heads. "
After running the numbers from the parallel bore drainage
project, Knott and Wojtkiewicz plan to use the Tri-Loc pipe and
the OTS System on future projects, as well. " For thicker, larger-diameter pipe, this can be a cost saver for our customers and will
help our team stay productive. "
These two labor-saving technologies helped BTrenchless complete this project's second bore in short order and provide a great
solution on future projects. *
