Conductivity Cone
Resistivity is a basic parameter that characterizes the electrical conductivity of the soil and is one of the inherent characteristic parameters of the soil. It depends on the porosity, pore shape, pore liquid resistivity, saturation, water content, solid particle composition, directionality, and cementation state of the soil. Therefore, resistivity can reflect some special properties such as liquefaction of foundation, porousness, and density of soil.
Wave Velocity Cone
The wave velocity test is one of the main means of geotechnical engineering investigation for seismic effects on engineering sites and foundations. By measuring the shear wave velocity, the shear modulus of the soil can be calculated, which in turn can be used to classify the type, category, and dynamic parameters of the foundation soil and provide a basis for the analysis of the seismic response of the site.
Magneto Cone
Magneto cones are used to detect underground magnetic anomalies and are applicable to search both underground magnetic ores and UXO(unexploded ordnance).
Single-bridge Cone
Test Range: cone resistance + sleeve friction: 0~75MPa Test Accuracy: better than 0.5% Type of signal: analog Working area: onshore Cone: 2cm², 5cm², 10cm², 15cm², 20cm²
Pore Water Seepage Cone
Test Method: Under continuous negative pressure pumping on the ground, the seepage characteristics of groundwater (pore water) are determined by measuring the flow rate of groundwater (pore water).
Hydra-sampler Cone
When the cone penetrates into the predetermined formation, the trigger mechanism makes it become a fluid (pore water) sampler. Negative pressure in the sampling chamber allows fluids from the formation to pass through a permeable membrane into the chamber for storage, and the fluids are removed from the chamber when the cone is recovered to the ground.
Ball-Bar
10 times of area compared with conventional cone tip. Ball shape. Compatible with different sizes of cones. Customized design is available.
T-Bar
10 times of area compared with conventional cone tip. Cylindrical shape. Compatible with different sizes of cone. Customized design is available.
Double-bridge Cone
Test Parameters: cone resistance, sleeve friction Test Range: cone resistance 0~75MPa, sleeve friction 0~1MPa (can be customized) Test Accuracy: cone resistance better than 0.5%, sleeve friction better than 1%. Cone: 2cm², 5cm², 10cm², 15cm², 20cm²
Triple-bridge Cone
Test Parameters: cone resistance, sleeve friction, pore water pressure Test Range: cone resistance 0~75MPa, sleeve friction 0~1MPa, pore water pressure 0~4MPa (can be customized) Test Accuracy: cone resistance better than 0.5%, sleeve friction better than 1%, pore water pressure better than 0.5%. Cone: 2cm², 5cm², 10cm², 15cm², 20cm²
Particle Sampler Cone
When the cone penetrates into the predetermined formation, the trigger mechanism makes it become a sampler, then soil sampling can be carried out by continuing to penetrate, and the soil are removed from the chamber when the cone is recovered to the ground.
Temperature Cone
Soil temperature, low-temperature gradient, thermal conductivity, and other information are important parameters of thermal exploration and can be used in the survey to find underground constant temperature layer, mineral resources, oil and gas resources, and natural gas hydrate.
