Static and/or dynamic penetrometric tests in a single device
The Pagani Geotechnical TG 63-150 penetrometer can be configured on request to perform static penetrometric tests (CPT), or both static (CPT) and continuous dynamic (DP) penetrometric tests.
With regards to the dynamic tests, depending on the most commonly tested soil types, the penetrometer can be equipped with different hammer systems (DPSH super heavy, DPH heavy, or DPM medium).
It also allows disturbed samples to be taken, as well as undisturbed samples which permit better stratigraphic interpretation.
The TG 63-150 sets itself apart with its high energy efficiency.
Approximately 78% of the energy is transmitted to the rods. It guarantees perfect verticality when driving in the rods. It reduces testing times by allowing the rods and their liner tubes to be driven into the ground at the same time. It makes removal of the entire rod possible. It features an anchoring system installed on the mast which allows machine positioning times to be significantly reduced, along with the stress when driving the test equipment into the ground. The TG 63-150 penetrometer features a hydraulic tracked carriage which offers excellent manoeuvrability, even on uneven terrain. It can even be positioned on very steep slopes thanks to its three stabilisers, and the mast can be tilted continuously, meaning it is always perfectly vertical.
The TG63-150 is a highly flexible machine, which can be used by one single operator. Static penetrometric tests can be performed with a mechanical bit (Begemann) and manual acquisition (CPT), or using different (optional) bits such as the piezocone (CPTU) or seismic piezocone (S-CPTU) which offer a more reliable stratigraphic interpretation and determination of the profile of the speed of the shear waves (Vs).
The static/dynamic method allows information to be obtained along verticals composed of terrain with different mechanical characteristics (from very soft to very hard and compact), while it is possible to overcome particularly hard strata thanks to a rotary head which allows pre-drilling (optional).
