With the new seismic piezocone, an electric tip equipped with one or two terns of geophones, it is possible to detect the seismic waves P and S, making a seismic classification of the ground.
In a single test it will be possible to obtain the values of Qc, Fs, u2 and the data of the propagation speed of the waves in the ground (Vs - Vp).
You can also get data about the dissipation time (time measured between measurement of the overpressure obtained during the driving stage and the pressure measured when releasing the driving pressure).
TGAS-12 acquisition system
P-Double Seismic Cone
TGAS-12 is an acquisition system for CPTu + S-CPTu tests which allows you to work in the field in any weather conditions.
Provided with a capacitive touch-screen monitor with good visibility even in direct sunlight, it allows operators to perform CPTu + S-CPTu tests via simple and fast procedures, without the assistance of a PC in the field.
Provided with an intuitive monitor touch-screen, it doesn't require the aid of a portable PC and it can be easily installed on the machine on site.
The collected data can be downloaded via a simple USB key.
