Direct Push Technologies - Geoprobe
WDC Exploration & Wells operates the newest and most powerful high-capacity direct push machines from GeoprobeŽ (PDF).
Model7730DT
This is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a rubber track wide-base platform. The heart of the 7730DT is the powerful GH62 hammer which was designed specifically for direct push applications. Highly productive in both shallow and deep sampling venues. The stronger, wider undercarriage allows the 7730DT to be used on concrete or pavement, and enables the machine to readily negotiate in tight, confining work areas and on offroad, rugged terrain.
Model7700/PC111
WDC has combined state of the direct push drilling technology with a probe carrier that makes use of 160 cubic feet of dry storage space. The brand new 7700 features a 77-inch stroke, 5-inch diameter main cylinder supplies 35,000 lbs. of down force and great than 47,000 lbs. pull. Equiped with a GH62 hammer that hits at 1920 blows per minute and delivers forces great then 80,000 pounds per blow to the top of the probe rod. Designed to switch operations from direct push to augering in less then 5 minutes.
Model6620DT
The upgraded undercarriage allows the 6620DT to be outfitted with augers, winches for tool placement and retrieval, and even the DH100 Auto Drop Hammer for geotechnical applications. An auxiliary hydraulic system supports mixing and injection systems for rapid in-situ chemical oxidation reagent delivery to contaminated subsurface soils.
