The Geoprobe® 3230DT is a mid-sized tracked drill rig combining advanced direct push functionality with traditional geotechnical auger rig and high-speed rotary drilling capabilities. The many features of the 3230DT come together to create a rig that is efficient at what it does. Using customer feedback and experience, we combined all of the features that make drilling easy into this machine, creating a platform that performs well in direct push and rotary applications.

The patented four function Geoprobe® CB Combo Head (Direct Push Hammer, Rotation, Head Clamp and Auto Drop Hammer) is key to the exceptional performance of the 3230DT.  50K downforce.  80K pullback.  99 hp engine. Quick and efficient.

CB Combo Head

CB Combo Head

The patented CB Combo Head is the heart of the 3230DT and perfect for augering and high-speed rotary work. A 6-speed variant of the combo head is available with 8,500 lbs. of torque and top speed of 800 rpm. For projects that require direct push sampling or driving large casing, the integrated GH70 Hammer has become standard.

Completing the CB Combo Head is our patented hydraulic head clamp that is built-in and allows users to safely and quickly hold or pull rods, casings, or augers while maintaining an open tool string. It easily manages the 80,000 lb. of pullback from the drill mast. Additionally, the combo head has functionality for direct push / percussion, mud rotary, air rotary, and rock coring.

Direct driving Geoprobe® 6.0-in casing with a removable solid point using a 3230DT.

Typical tooling that can be run with the 3230DT include:

  • 60-in. Direct Push Tooling
  • Probe Rod Sizes: 6.0 in., 4.5 in., 3.75 in. (recommended), 3.5 in., 2.25 in.
  • DT60, DT45, DT37, DT35 Dual Tube Soil Sampling
  • SP22 Groundwater Sampling
  • 2.0 in. Prepacked Monitoring Well Installations
  • Up to 8.25 in. HSA System
  • Traditional Split Spoon
  • Geoprobe® Interlocking Split Spoon

Video: 3.75-inch Tooling System

The DT35 Soil Sampling System, designed for use with 3.5 in. probe rods, uses a unique combination of the cutting shoe, sheath, and liner retainer to allow efficient recovery of samples in formations ranging from plastic clays to saturated sands. The DT35 system is designed to quickly recover samples well below the water table. Problems with liner failure or having the liner lodge in sample sheath are virtually eliminated with this system.

A DT45 sample.

A DT45 sample.

The DT45 Sampling System is specifically designed for use with the Geoprobe® 3230DT. This sampler provides a cased hole while providing a 3 in. diameter core sample. The durable DT45 Sampling System uses the Geoprobe® 4.5 in. probe rods as the outer casing along with the option of using standard 1.25 in. or 2.25 in. probe rods as inner casing to pull core samples.

Video: DT60 Soil Sampling System Overview

The DT60 sampling system is the largest dual tube system from Geoprobe®. It utilizes 6 in. OD percussion driven casing and collects a 4 in. diameter soil sample. Unlike most other sampling systems, the DT60 uses a patented split sheath which gives the user the option of not using a liner.

In addition to its soil sampling capacity, the DT60 system can also be used to install 2 in. monitoring wells without driving a second tool string. That means you can collect continuous soil cores and install a 2 in. prepack or conventional well within a 6 in. borehole with no expendable points or cutting shoes – all in one shot! 

A auger is used to reach the desired depth for Split Spoon Sampling.

The 3230DT is capable of running augers up to 8.25-in. 

Hollow Stem Augers (HSA) are commonly used to set groundwater monitoring wells for environmental and for geotechnical SPT applications. With the option of an augerhead on Geoprobe® machines you can turn hollow stem augers with the same machine you had just been using for percussion probing. When you are ready to auger, just fold out the augerhead and secure with one bolt or pin. This added flexibility has been a big hit with field operators.

Video: Interlocking Split Spoon Overview

The interlocking design self aligns during assembly and is quick to disassemble

The interlocking design self aligns during assembly and is quick to disassemble

Our patented interlocking split spoon sampler is a unique geotechnical innovation from Geoprobe® that is engineered to greatly benefit your field team. It is built to be 2X stronger, last longer, and saves both money and field time over a conventional split spoon. Additionally, it meets ASTM Standard D1586.

The interlocking design provides axial alignment of the tube halves, making for a quicker assembly of the sampler. Each time it goes together it self aligns, creating a perfect fit. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. The threads are a multi-lead, which requires fewer turns during assembly and disassembly over conventional split spoons. Less time is spent during assembly and disassembly, which speeds up each test interval.

In additional to time savings, the interlocking split sheath has two times the strength and durability of conventional split spoons. Enhanced material properties and manufacturing result in greater longevity. Design plays an important role as well. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

*Split tube soil sampling system manufactured under U.S. Patent 9,551,188

The Geoprobe® Screen Point 22 System

The Geoprobe® Screen Point 22 System

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen.

The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-in. Lightweight Center Rods or PVC riser.

The screen head adapts to either a stainless steel or PVC screen. Designed for tough probing conditions, the fully retrievable sampler works well with the 8040DT machine or with 77 or 66 Series machines.

Video: Hydraulic Liner Extruder Overview

This tool sure makes life easier in the field. In the middle of a busy day, you don’t need the hassles associated with a stubborn, stuck liner.

The Geoprobe® Hydraulic Liner Extruder is simple to use and can be adapted to most Geoprobe® machines with auxiliary hydraulics. “It mounts to the machine’s side receiver hitches in just a few minutes,” says Dave Golden, Project Lead, “and it’s perfect for pushing sluggish or stuck liners from the Macro-Core® sample tubes.” A two-piece adapter converts the extruder assembly to accommodate larger diameter DT325 sample tubes. “It won’t get every liner every time,” Dave added, “but our customers will appreciate having this device in the field for all of the stuck liners it does free.”

Using the Hydraulic Liner Extruder is simple. A Macro-Core®, DT22, DT325, or DT45 Sample Tube with the sluggish liner is threaded on to the front end of the extruder. As the hydraulic "push" is applied to the opposite end of the extruder, the liner is slowly pushed from inside the Sample Tube and out the end of the extruder.

2.25 in. Spring Assisted Pull Cap - Pin (Left) and Box (Right)

The 2.25 in. Spring Assisted Swivel Pull Cap is designed to reduce operator fatigue when adding or removing sections of rods to the inner tool string. The internal springs of the pull cap bear the weight of the rod string. With minimal effort, the operator can adjust the rod string up or down when threading or unthreading the rods. The natural self-alignment of the rod string prevents tipping off center and binding of the threads.

The durable DT45 Sampling System uses the Geoprobe® 4.5 in. probe rods as the outer casing along with the option of using standard 1.25 in. or 2.25 in. probe rods as inner casing to pull core samples.

DT60

Video: DT60 Soil Sampling System Overview

The DT60 sampling system is the largest dual tube system from Geoprobe®. It utilizes 6 in. OD percussion driven casing and collects a 4 in. diameter soil sample. Unlike most other sampling systems, the DT60 uses a patented split sheath which gives the user the option of not using a liner.

In addition to its soil sampling capacity, the DT60 system can also be used to install 2 in. monitoring wells without driving a second tool string. That means you can collect continuous soil cores and install a 2 in. prepack or conventional well within a 6 in. borehole with no expendable points or cutting shoes – all in one shot!

Hollow Stem Augers

A auger is used to reach the desired depth for Split Spoon Sampling.

A auger is used to reach the desired depth for Split Spoon Sampling.

The 3230DT is capable of running augers up to 8.25-in. 

Hollow Stem Augers (HSA) are commonly used to set groundwater monitoring wells for environmental and for geotechnical SPT applications. With the option of an augerhead on Geoprobe® machines you can turn hollow stem augers with the same machine you had just been using for percussion probing. When you are ready to auger, just fold out the augerhead and secure with one bolt or pin. This added flexibility has been a big hit with field operators.

Interlocking Split Spoon

The interlocking design self aligns during assembly and is quick to disassemble

The interlocking design self aligns during assembly and is quick to disassemble

Our patented interlocking split spoon sampler is a unique geotechnical innovation from Geoprobe® that is engineered to greatly benefit your field team. It is built to be 2X stronger, last longer, and saves both money and field time over a conventional split spoon. Additionally, it meets ASTM Standard D1586.

The interlocking design provides axial alignment of the tube halves, making for a quicker assembly of the sampler. Each time it goes together it self aligns, creating a perfect fit. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. The threads are a multi-lead, which requires fewer turns during assembly and disassembly over conventional split spoons. Less time is spent during assembly and disassembly, which speeds up each test interval.

In additional to time savings, the interlocking split sheath has two times the strength and durability of conventional split spoons. Enhanced material properties and manufacturing result in greater longevity. Design plays an important role as well. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

SP22 Groundwater Sampling

The Geoprobe® Screen Point 22 System

The Geoprobe® Screen Point 22 System

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen.

The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-in. Lightweight Center Rods or PVC riser.

The screen head adapts to either a stainless steel or PVC screen. Designed for tough probing conditions, the fully retrievable sampler works well with the 8040DT machine or with 77 or 66 Series machines.

Hydraulic Liner Extruder

Video: Hydraulic Liner Extruder Overview

This tool sure makes life easier in the field. In the middle of a busy day, you don’t need the hassles associated with a stubborn, stuck liner.

The Geoprobe® Hydraulic Liner Extruder is simple to use and can be adapted to most Geoprobe® machines with auxiliary hydraulics. “It mounts to the machine’s side receiver hitches in just a few minutes,” says Dave Golden, Project Lead, “and it’s perfect for pushing sluggish or stuck liners from the Macro-Core® sample tubes.” A two-piece adapter converts the extruder assembly to accommodate larger diameter DT325 sample tubes. “It won’t get every liner every time,” Dave added, “but our customers will appreciate having this device in the field for all of the stuck liners it does free.”

Using the Hydraulic Liner Extruder is simple. A Macro-Core®, DT22, DT325, or DT45 Sample Tube with the sluggish liner is threaded on to the front end of the extruder. As the hydraulic "push" is applied to the opposite end of the extruder, the liner is slowly pushed from inside the Sample Tube and out the end of the extruder.

Macro-Core® is a registered trademark of Kejr, Inc., Salina, KS.

2.25 in. Spring Assisted Pull Cap - Pin (Left) and Box (Right)

The 2.25 in. Spring Assisted Swivel Pull Cap is designed to reduce operator fatigue when adding or removing sections of rods to the inner tool string. The internal springs of the pull cap bear the weight of the rod string. With minimal effort, the operator can adjust the rod string up or down when threading or unthreading the rods. The natural self-alignment of the rod string prevents tipping off center and binding of the threads.
