The CPT Vehicle utilizes advanced hydraulic transmission technology to automatically press the static exploration probe into the soil at a consistent and uniform speed. By measuring the resistance of the probe as it contacts the soil, the system converts physical data into electrical signals through resistance strain gauges.
The surface measuring instrument records and determines vital mechanical parameters of the soil, which are essential for foundation design. This equipment is highly versatile, making it ideal for working on soft soil, cohesive soil, old clay, loess, and sandy soil environments.

The static cone penetration test is a critical in-situ testing method for engineering geological exploration, serving the following purposes:
1. Soil Stratification
Divide soil layers and investigate uniformity of soft and hard interlayers.
2. Engineering Characteristics
Evaluate bearing capacity, compression properties, and shear strength.
3. Foundation Reinforcement
Check the compactness of artificial fill and effectiveness of foundation reinforcement.
