Advantageous for determining liquefaction and confirming the effectiveness of ground improvement work! It captures ground information in real-time.
We would like to introduce our "CPT" (Cone Penetration Test).
The cone is inserted at a constant speed of 2 cm/s, capturing real-time ground information such as tip resistance qc, sleeve friction fs, and pore water pressure u.
Data is read approximately every 2.5 cm, and automatic soil classification is performed. Compared to boring surveys that conduct standard penetration tests (SPT) every meter, the accuracy is 40 times greater.
【Features】
■ Data is read approximately every 2.5 cm, and automatic soil classification is performed, resulting in 40 times the accuracy compared to boring surveys.
■ Investigations can be conducted at three locations per day to a depth of about 20 m, achieving 3 to 4 times the efficiency of boring surveys.
■ Liquefaction assessment using CPT complies with the "Guidelines for Structural Design of Building Foundations" (2001, Architectural Institute of Japan).
