UCT Is Go-To Place For New Technologies
In a similar way to the pipe jacking process, Herrenknecht Direct Pipe machines excavate the borehole. The excavated material is transported via a slurry circuit, which runs in the laid pipeline to the separation plant aboveground. The Pipe Thruster takes over the function of the main jacking station and pushes the pipeline with the coupled Direct Pipe machine forward. The required force is transmitted to the pipeline and the cutterhead via the clamping unit of the Pipe Thruster.
The Universal Navigation System developed by Herrenknecht makes it possible to master and monitor curved drilling profiles accurately by using a gyro compass and a hydraulic water leveling system.
• Single-step method leads to rapid installation of product piping and pipelines;
• No time needed for coupling pipes (Microtunnelling) or drill rods (HDD);
• Pipeline can be installed pre-welded and already tested; and
• Costly shaft construction is unnecessary – only simplified surface entry and exit pits are required.
UCT was the ideal venue for Vermeer Corporation to introduce two new products designed specifically to assist with geothermal field loop installations. The D20x22FX Series II will be the industry’s first flex-angle drill capable of drilling at any specified angle ranging from 18 to 90 degrees. Engineered with input and feedback from contractors who specialize in geothermal loop system installations, specifically for residential applications, the D20x22FX Series II is another Vermeer product innovation in response to the increasing worldwide focus on renewable energy.
Capable of completing vertical and steep-angle geothermal loop installations, the D20x22FX Series II is also a fully functioning horizontal directional drill that can install horizontal loops as well as conventional utilities. This feature offers exceptional adaptability in meeting varying project specifications.
“The D20x22FX Series II will allow contractors involved with geothermal installations a great amount of flexibility,” says Ed Savage, trenchless segment manager at Vermeer. “With both vertical and horizontal drilling capabilities, and the option to select any drilling angle from 18 to 90 degrees, this drill will help enhance the efficiency and productivity of geothermal field loop installations. It’s like getting the capability of both a vertical and horizontal directional drill in the same machine.”
