Obtain a large amount of ground information in a short period! It is possible to measure sandy soils with an N value of around 30 to 50, and cohesive soils with an N value of around 20.
The "Automatic Ram Sounding Test" automatically drops a hammer weighing 63.5 kg from a height of 500 mm, recording the number of blows (Nd) required for the tip cone to penetrate 200 mm. The Nd value obtained from this test is considered to be approximately equal to the N value from the standard penetration test. Note that sample collection, as done in the standard penetration test, is not possible. Additionally, it can measure sandy soils with an N value of around 30 to 50, and cohesive soils with an N value of about 20. 【Test Machine Features】 ■ Dynamic cone penetration testing machine developed by Borro in Sweden ■ Dimensions: Height 2.8m × Width 0.8m × Depth 0.9m ■ Total machine weight: 215 kg ■ Hammer weight: 63.5 kg ■ Hammer drop height: 500 mm ■ Hammer drop frequency: 24 times/minute *For more details, please refer to the PDF document or feel free to contact us.
