Vertek - Model HT DataPack - Portable Cone Penetrometer Test (CPT)
The HT DataPack is a field portable Cone Penetrometer Test (CPT) data acquisition and analysis package which works with all digital HT cones. Developed as a simple ‘all-in-one’ solution for the Geotechnical CPT service providers, this version incorporates USB for ease of connectivity.
The HT DataPack is housed in a water-resistant instrument case and requires use of a COTS, Windows based laptop. Vertek recommends use of a ruggedized computer for CPT applications.
Report Quality Field Plots
The HT Datapack comes with a complete software package for acquisition, processing, and plotting CPT data. The DataPack generates report-quality plots in the field on any Windows supported printer (color or gray-scale). Plot scales can be set automatically and a wide variety of engineering parameters can be selected. With current communication technology data is easily transmitted to project engineers anywhere.
Efficient Data Collection
A digital CPT probe is the heart of the system. The standard probe includes tip, sleeve fiction, inclination, pore pressure sensors, and dual axis geophones. The system stores unlimited data points per channel for each test and is saved to disk after each sample to ensure data integrity. Measurements are also plotted in real time on the computer screen during the push, providing immediate data from the probe and alerting the operator to potential problem layers. Optional shut down circuits can be incorporated to stop the push unit if pre-set stress alarm levels are exceeded.
High-Powered Data Analysis
Data analysis software is included with the DataPack, allowing the operator to display both the test data and derived parameters in formats appropriate to client requirements. Standard classification algorithms based on sleeve friction and pore pressure ratios are included for classification of soil types. Journal published empirical correlation are employed to estimate friction angle, undrained shear strength, standard penetration test (SPT) blow count, relative density, and over consolidation ratio. Pore pressure algorithms are built into the software and the results can be used to estimate the hydraulic
conductivity of cohesive soils.
Vertek recommends use of ruggedized computers with daylight readable screen for CPT operations. Vertek can supply the computer or Vertek will outfit the customers desired computer. The computer should have a minimum of 4GB RAM. The CPT software will work with both Windows 7 and 8.
