Working principle
Penetration process: The probe penetrates the soil at a constant speed (usually 2 cm/s) and measures the cone tip resistance and sidewall friction.
Data collection: The transmitter records data in real-time and transmits it to ground equipment.
Data analysis: Processing data through software to generate soil profile maps and other results.
Measurement parameters
-Cone tip resistance (qc) reflects the compactness and strength of the soil.
-Side wall friction force (fs) * *: reflects the friction characteristics between the soil and the probe.
-Friction ratio (Rf): The ratio of sidewall friction to cone tip resistance, used to determine soil type.
-Pore water pressure (u) reflects the drainage conditions and consolidation characteristics of the soil.
Application Fields
-Geotechnical investigation: Determine the distribution of strata and soil characteristics.
-Foundation design: Evaluate the bearing capacity and settlement characteristics of the foundation.
-Environmental Investigation: Detecting underground pollution and groundwater conditions.
-Earthquake Engineering: Evaluating Soil Liquefaction Potential.
Advantages
-Fast and efficient: Continuous penetration, real-time data collection.
-High precision: Provides continuous soil profile data.
-Multi functional: capable of measuring multiple parameters and widely used.
-Environmental Protection: No need for sampling, reducing interference with the environment.
Summarize
Soil static cone penetration testing equipment is an important tool in geotechnical engineering, which can quickly and accurately obtain soil characteristic data and is widely used in engineering investigation, foundation design, environmental investigation and other fields.
