Dando - Model TROD -Terrier Rig Tooling

Drive Rods

In order to drive samplers and probes into the ground the Dando Terrier uses solid 1m rods to connect the tool to the drive head.

Sampler Kits

Typically 1m long, samplers are used to produce high quality undisturbed samples in soft to medium conditions in both consolidated and unconsolidated geology.

In addition to the sample tube, removable plastic liners can be installed within the sample tube itself. These aid sample presentation and allow easy transportation. Liner end caps can be used to retain the sample and for moisture retention.

If drilling in unconsolidated ground a basket catcher can be added to help retain the sample within the liner.

Duplex Casing

The Dando Duplex Drive system is an innovative system that allows the user to take undisturbed samples while advancing  Duplex casing at the same time. As well as saving time this is very useful in soft ground conditions as it prevents the hole from collapsing as you drill deeper.

Dynamic Probing Rods

The dynamic probing technique involves driving a sacrificial or recoverable cone vertically into the ground using rods marked at 100mm intervals. The number of blows for each 100mm of penetration are recorded to measure soil resistance and quality

BWY Rods

Using the high rotary speed application and the side inlet swivel, the Terrier is ideally suited to drilling with a conventional coring barrel with air or water flush. Dando can supply BWY rods in lengths of 1m and 1.5m.
