Eustis Engineering can now perform complex jobs in tight spaces and reach previously inaccessible areas with the recent purchase of two devices, the Geoprobe® 6620DT and the Geoprobe® 540M.
These direct push rigs can both be used to perform cone penetration tests and conventional geotechnical sampling at shallow depths. Both models allow Eustis Engineering to perform work that previously had to be subcontracted.
Vice President of Operations, Larry Rome, said, “We wanted something that would make us more competitive. We needed more diversity in our equipment for sites with limited access.”
The 6620DT includes an overhead mast with an extension, and uses a wireless remote control. The 6620DT requires less than 12 feet of overhead clearance and can be placed on specialized equipment. Previously, our rigs needed 30 feet of overhead clearance. The machine is equipped with a built-in rotary spindle for hollow stem or solid stem auger sampling, and it features a hydraulic winch to help with tool placement.
The 6620DT can be placed on a specialized jack-up barge or a cargo buggy for operations over water. The 6620DT can perform splitspoon sampling with its self-contained automatic SPT hammer, and two sizes of Macro-Core sampling. Additionally, the unit has the ability to install shallow monitoring wells and other instrumentation.
Senior Project Manager and Vice President of Testing, Travis Richards, P.E., said, the 6620DT “does a little bit of everything. It’s the Swiss Army knife of soil exploration.”
The 540M can be used for limited-access CPT probing, as it requires only a 32-in. doorway. It can also be used on an airboat for coastal terrains. This small, lightweight rig can be anchored to the floor, and can be used for very shallow sampling.
This tiny Geoprobe has greatly expanded our capabilities. Previously, our rigs required a doorway that was 10 feet wide and 12 feet tall.
