crawler-type CPT Vehicle for Hydraulic Static Cone Penetrometer
The working principle
Cpt Vehicle uses hydraulic transmission technology to automatically press the static exploration probe into the soil at a uniform speed, and uses the resistance of the probe to contact the soil to convert it into an electrical signal through resistance strain. The measuring instrument on the ground measures, records, and determines the relevant mechanical parameters of the soil for foundation design. It is suitable for working on soft soil, cohesive soil, old clay, loess, and sandy soil.
The hydraulic crawler static exploration vehicle adopts many advantages of similar products at home and abroad, with novel design, compact structure, small size and high power, a
Feature
1. With track support and walking, static exploration operations can be carried out in harsh environments such as beaches, river beaches, sandy soils, paddy fields, etc., and the road can still be walked on if the road is icy.
2. Advanced hydraulic system, using split-type combined multi-way directional valve, compact structure, small size, convenient installation, low pressure loss, and good pressure overload characteristics of the overflow valve.
3. The unique sliding hydraulic anchoring device is adopted. When the static penetration is working, the hydraulic anchoring device is gently slid to the outside of the vehicle, and the anchor is rotated by the high-power anchoring motor, and the device can be retracted after the work is completed. ,Convenient,
4. This Hydraulic Static Cone Penetrometer can be used for multiple purposes in one machine. It is not only an ideal equipment for static cone penetration testing, but also with accessories, which can be extended for pore pressure static detection (CPTU), self-drilling side pressure (PMT), flat shovel side expansion (DMT) , Cross plate shear (VCT), press-in wave velocity (WVT) and other in-situ tests.

Static cone penetration test is an in-situ testing method in engineering geological exploration, which can be used for:
1. Divide soil layers, determine soil layer categories, and investigate the uniformity of soft and hard interlayers and soil layers in both horizontal and vertical directions;
2. Evaluate the engineering characteristics, allowable bearing capacity, compression properties, undrained shear strength, horizontal consolidation coefficient, saturated sand liquefaction degree, sand compaction degree, etc. of the foundation soil;
3. Explore and determine the bearing layer of the pile foundation, estimate the possibility of pile driving and the bearing capacity of a single pile;
4. Check the compactness of artificial fill and the effectiveness of foundation reinforcement.
