What is geoprobe drilling?

Geoprobe sampling involves taking samples from a specific location at defined depths. It can happen from the ground level down, or beginning at a certain depth. For taking samples from ground level down, the rig drives an outer casing, with a drive shoe installed, into the ground.

How deep can a Geoprobe drill?

It can drill through surface pavements 12 inches (305 mm) or more in thickness and probes beneath them. It can be used for collecting soil cores, groundwater samples, and soil gas samples.

Is Geoprobe direct push?

Direct Push Tooling Geoprobe pioneered Direct Push Subsurface Sampling Technology in 1987. A direct push machine “pushes” soil sampling tools and sensors (soil probes) into the ground without the use of drilling to remove soil to make a path for the tool.

What is direct push drilling?

Direct push technology, often referred to as DPT, uses the static weight of the rig combined with a hydraulic hammer to advance tooling or instrumentation through the subsurface. Unlike rotary, the drill cuttings are not removed from the hole.

What does Geoprobe mean?

geoprobe in British English (ˈdʒiːəʊˌprəʊb) noun. geology. a probing device used for sampling soil.

What is a sonic drill rig?

Sonic is an advanced form of drilling which employs the use of high-frequency, resonant energy generated inside the Sonic head to advance a core barrel or casing into subsurface formations. Simultaneously rotating the drill string evenly distributes the energy and impact at the bit face.

How much does a Geoprobe 7822dt weigh?

Base Unit Weight: 8,160 lb. (3,701 kg.) With Typical Options: 9,560 lb. (4,336 kg.)

What is geotechnical drilling?

Geotech drilling is used to analyze the site. It involves collecting rock and soil samples at representative levels below the desired foundation depths, at a collection of different locations in the building site. Drilling and core samples are used to create a soil profile for the site.

How does a split spoon sampler work?

The split spoon sampler is a tube split into two equal halves lengthwise. The two halves are locked together during the sampling activities and released to retrieve the samples. At bottom end of the sampler sits a driving shoe. This is what cuts into the soil and provides the sample that goes up into the tube.

Does Sonic drilling require water?

The core barrel is advanced using sonic frequencies. When necessary this step can be performed using no fluids, air, or mud.

How much does Sonic drilling cost?

q Drilling rates range up to 260 feet per day. q Costs range from $70 to $300 per foot depending upon the drilling system used, the drilling approach, the site geology, etc.

How much do Geoprobes weigh?

Base Unit Weight: 8,160 lb. (3,701 kg.) With Typical Options: 9,560 lb.

How big is a Geoprobe 6011dt drill rig?
