Demonstration of SPT Split Spoon Sampler

#standardpenetrationtest #spt #SPTSplitSpoonSampler
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. At the other end of the tube is a coupling that allows it to connect to the drilling rod. Once a sample is taken, the operator removes the ends from the tube. This allows the tube to “split” open. Representative samples can be taken and put into containers for shipping to a lab for analysis, observed and field tested in the field, or discarded in a proper waste container if not warranted for the investigation.
