Wheeled hydraulic static cone penetrometer vehicle for soil CPT testing machines
The working principle of the wheeled static exploration vehicle is the same as that of
other hydraulic static exploration machines; it uses hydraulic transmission technology
to automatically press the static exploration probe into the soil layer at a uniform
speed, and uses the resistance of the probe to contact the soil layer 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.
2Y-20E wheeled static detection vehicle adopts many advantages of similar products
at home and abroad, with novel design, compact structure, small volume, high power,
and has the following characteristics:
1. Using self-driving walking, it can carry out static exploration operations in harsh
environments, with fast moving speed and reduced work intensity.
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 staticpenetration 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 machine 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.
