The new Seismic Piezocone is fitted with a set of Geophones, to detect P and S seismic waves which add to the investigative performance of the Piezocone and the possibility to carry out a Seismic classification of the terrain.
In a single test, it will be possible to achieve Qc, Fs, u2 values and data regarding the propagation speed of the waves in the terrain (Vs – Vp) in real time "true time".
Double set of geophones positioned at 9-11/16"(50 cm) apart not only allows for more seismic data to be collected in a simpler fashion but also the time difference in the arrival of a seismic wave between one set and the other (true interval)
The three geophones for collecting the data on the seismic waves are positioned orthogonally between them, inside the piezocone unit, one for gathering data on the P waves and two for gathering data on the S waves, allowing for the data to be received from any angle
System for generating seismic waves
The seismic waves are generated on the surface using a new stop system separate from the Penetrometer. Using this kind of test, it is possible to obtain the data of the S waves and P waves more easily and faster.
A trigger fitted on a club/hammer will allow the acquisition process to be launched at the precise moment it generates the wave, impacting on the disk or joist.
Configurations suited to any situation
The P-Seismic Cone mono-triaxial Seismic functions with the TGAS-12 data-logger, the latest acquisition product by Pagani Geotechnical Equipment which, as well as the CPTu and S-CPTu tests allow you to also carry out Dissipation and Ground Temperature tests.
The new software program guides the operator at each stage and five tabs simplify the passage between test types, while the capacitive touch-screen monitor makes its use even more fluid and intuitive.
