CPTU testing with digital piezocones

Measure excess pore pressure that is generated during soil penetration with our digital CPTU piezocone testing system. In the quotations, Gouda Geo-Equipment issues a clear distinction is made between on one hand the CPT penetrometer pusher (this could either be a truck-based, crawler-based, trailer-based or stand-alone unit) and on the other hand the CPT system (this could either be mechanical or electrical CPT(U) system with automated or manual recording). This page describes the “professional” base kit one would need to do CPTU testing with a piezocone with a CPT penetrometer pusher of one’s choice.

CPTU testing with a piezocone offers the opportunity to measure simultaneously the cone resistance (qc), the local sleeve friction (fs) and the pore pressure (p) at predetermined intervals (every 10, 5, 2 or 1 cm depending on the required accuracy). Since the piezocone is equipped with a built-in XY-inclinometer, the deviation of the vertical axis in 2 directions is registered as well. All data are synchronized with depth.

For the performance of CPTU tests Gouda-Geo offers a complete and universal system to do these tests according to national and international standards. It is to be used in combination with a PC computer and can be used on any penetrometer pusher and can be extended (at extra costs) with extra sensors, like pH/ORP, temperature, seismic, magnetometer, and alike.

The base kit consists of the following components:

The CPT-logger is the heart of the data acquisition system for CPT(U) testing. It is to be used in combination with a standard laptop or industrial computer and CPT-Explorer data acquisition software.

The CPT-logger combines the following functions:

  • It supplies power to the attached electric cone or piezocone
  • It digitizes the incoming analogue signals
  • It conditions the incoming digital signals from the depth synchronization
  • It synchronizes all data for processing on attached computer

The CPT-Logger is compatible with all compression and subtraction type digital CPT piezocones. The high-grade waterproof housing makes the unit extremely suitable for working in the field, its compact design assures the use of little space.
