Types of CPT Equipment
Cones
Cone technology has seen major developments over the past 20 years. The standard CPT cone now measures pore pressure and is referred to as a piezocone. The pore pressure element can also be mounted in one of three positions, depending on ground conditions and the purpose of the test. Over recent years, the importance of temperature effecting the electronics inside the cone has been recognised and this has led to better temperature compensation.
Rigs
CPT rigs come in all shapes and sizes depending on what is needed for each particular project. The larger the rig the more reaction weight it will have to push the cone in the ground. However, it is not always the case that you need a large rig to achieve the required depths in a certain ground condition. You also don’t always have the space for a large CPT rig so smaller ones may need be deployed instead.
Rigs are often divided into wheeled and tracked versions and these can come in different sizes. You can also get rigs that have both wheels and tracks on them, known as track-trucks. A good thing about the larger rigs is that they provide comfortable places for work not only for the CPT operator but also the supervising engineer.
Modular soil sampler
This device allows you to use your CPT push system to easily and reliably obtain soil samples.
Groundwater sampler
This device can be utilized to collect a discrete sample from an area of interest and allows the exploration to be grouted immediately after the sample is obtained, decreasing migration.
Grouting modules
These devices can be attached behind the cone to tremie grout the borehole upon retraction or can be used with a specialized cone that deposits a disposable tip at the end of a sounding and grouts the annular space created during retraction.
Conesipper
This module attaches behind a normal CPT cone to take liquid or gas samples as the cone is pushed into the ground. Samples can be obtained from multiple depths during a single sounding, saving time and money.
SMRT (soil moisture, resistivity and temperature) module
This multi-purpose module can provide long-term data for applications such as irrigation or monitoring landfill sites.
VTK Video Module
This module incorporates real-time video screening with LED hydrocarbon fluorescence detection.
Benefits of CPT Equipment
Continuous data
CPT provides continuous soil property data along the depth of the borehole, giving a detailed profile of soil behaviour.
01
Less disturbance
CPT causes less disturbance to the soil compared to SPT, making it suitable for sensitive environments or where undisturbed samples are required.
02
Automated data collection
CPT data collection is automated, reducing operator dependency and potential errors.
03
Variety of sensors
CPT can be equipped with various sensors, such as pore pressure sensors, allowing for the measurement of additional parameters.
04
Applications
Geotechnical
CPT provides information on the soil profile, which can be used to design foundations, provide quality control for ground improvement work or to check the condition of a levee or a dike, for example.
Hydrogeological
To analyse the level and flow of groundwater or the interaction between groundwater and the surrounding soil.
Geo-environmental
To check the length of unknown foundations or the presence of buried steel objects, but also to determine the presence of contaminants in the soil.
