Seismic cone
Features:
A simple and cost-effective subsurface method for determining the propagation of waves through the ground is to generate waves at the surface, for instance by means of a hammer, and then register them by means of the seismic cone in the soil.
The seismic cone is available with a 10 cm² and 15 cm² cone area. The parameters shear wave right, shear wave left and compression wave can be combined with the geotechnical parameters qc, fs and U. Also an inclinometer can be used. |

For a more accurate determination of the delta t over intervals, a second set of geophones can be placed 500 or 100 mm above the first set. With two CPT rigs so-called cross hole seismic cone tests can be performed.
The seismic waves can be measured with optional hardware and software for our Touch-Screen data loggers. |

Icone Seismic Module An increasing number of CPT operators switch over to the Icone system. The reasons are clear: lower costs, higher quality and easier operations. Another reason has been added: it is now possible to add seismic measurements to the standard soil parameters. The application functions as may be expected from the Icone system: simple, strong and reliable. The measuring sensors are incorporated in an adapter module that is clicked onto the back of the standard Icone. The CPT rods are then connected to the module in the usual way. The measured parameters are shear wave left/right and compression wave. The waves are measured by means of a triaxial set of accelerometers. The data is registered with the standard Icontrol datalogger with GOnsite! software and stored in separate files.

GOnsite has a stacking function for stacking weaker signals. Using the GO4! office software the data is exported to Excel. For more information contact the sales department, by telephone +31 (0)513 631355 or email: o.storteboom@apvandenberg.nl or j.de.lange@apvandenberg.nl.
