Field Operations
Soil Coring
Once you have competed probing, remove EC - Force probe as outlined in Section 6.
- Install drive coupler to rotating head by means of drive retainer (Figure 10)
- Install PETG liner onto cutting shoe and thread into sampling tube (Figure 11)
- Install sampling tube into drive coupler and push into soil.
Use slow and steady insertion speed and minimal
rotation to push core sampler into the soil. A brief
rotation at bottom of stroke will snap off the core in
tight clay, giving you a fuller core as you retract.
(Figure 12) Excessive rotation may affect the
condition of your cores. Figure 10
