Dynamic Cone Penetration Test: Automatic Rum Sounding Method

After experience of facility liquefaction in Great East Japan Earthquake, demand for liquefaction evaluation has been increased. Conventionally standard penetration test (SPT) has been conducted.

Our automatic rum sounding machine achieved faster preparation, faster operation work, and high mobility without compromising measuring accuracy, compared with conventional SPT device.

Applicable machine: CRS-12-2
