Which sampler is hammered into the soil to collect a shallow-depth sample?

• A. Push Tube Sampler
• B. Veihmeyer Tube Sampler
• C. A Trier Sampler
• D. Split Spoon Tube Sampler

Answer: (D)

When obtaining a shallow-depth soil sample in the field, the insertion method of the sampler matters. A sampler that is driven into the ground with a hammer is designed for rapid penetration and can reach shallow layers quickly. The split spoon tube sampler is specifically hammered into the soil; it has a hollow tube with two sides that split apart to capture the soil inside as it is driven down. This setup is commonly used in conjunction with a drop hammer in field tests like the Standard Penetration Test, making it well-suited for quickly collecting a shallow, representative sample. Push-in samplers, such as the push tube or Veihmeyer (Shelby) tube, are designed to be inserted by pushing rather than hammering, which is better for undisturbed samples but not the hammer-driven shallow sampling described. The Trier sampler is another method that involves driving a sampler into the soil, but the split spoon is the classic hammer-driven choice for shallow penetration and sample collection in many practice scenarios.
