What is Direct Push Technology (DPT)?

What is Direct Push Technology (DPT): A direct push machine “pushes” tools and sensors into the ground without the use of drilling to remove soil to make a path for the tool. Direct push machines rely on a relatively small amount of static weight combined with percussion as the energy for advancing a tool.

How does a DPT rig work?

A probe is pushed into the ground using hydraulic pressure, hence its name “direct push.” The DPT rods push to the depth desired to be sampled with the sampling unit mounted at the bottom of the string of rods being pushed into the ground. DPT units can range from small cart-carried rigs to very large truck or track-mounted rigs.

What is a 7822dt drilling rig?

Drillers seeking the production of rotary drilling rigs with the versatility to complete direct push sampling appreciate the compact 7822DT drilling rig. Designed to adapt to your changing work roles, the size to power ratio suits environmental work in tight urban cores or geotechnical work in tough remote terrain.

Why should you buy a Geoprobe® 7822dt drill rig?

Owners praise their Geoprobe ® 7822DT for opening the door to complete more challenging projects and efficiently run larger tooling options. The versatility of the drill rig to complete jobs historically slated for solely rotary drilling rigs often makes it the most utilized drill rig in the fleet.

What is a direct push drill?

Unlike methods that use rotary auguring to advance tools or install wells, thus generating a large volume of potentially contaminated drill cuttings, direct push methods use a hydraulically powered percussion hammer and the static weight of the vehicle on which the system is mounted.

What is DPT used for?

It is also used for collection of geochemical, geophysical, and hydrogeological data below ground. DPT was originally developed for agricultural and geotechnical soil evaluation, but its use quickly spread into environmental applications.
