Features:
• Sample through caving soil.
• Eliminate pre-probing with use of Dual Tube System.
• Recover samples consistently.
• Variety of sample sizes available.
G3 features:
• Thicker design
• Endure more push/hammer and pull back power
• Minimise chance of liner failure
Piston Sampling Application:
• The piston sampler is direct pushed using the dual tube system to the desired depth where sampling is to begin. (Step 1)
• Once at the desired sampling depth, the internal direct push extension(s) attached to the inner drive tip is removed. (Step 2)
• Next, an additional external direct push extension, the same length of the piston sampler, is added. (Step 3)
• At this point the sampler is pushed, and the sample is collected. (Step 4)
• Finally, the piston sampler is removed from the boring and the sample is retrieved. (Step 5)
Additional sampling intervals at greater depths can be retrieved using the same boring. There is no chance of losing the centre rod, and any caving/slumping that has occurred will not fill the piston sampler’s liner. Any material that prematurely enters the sampler and liner, when removing the internal components, is pushed out above the liner when the liner is filled from the desired sample interval.
