AF Shallow Core System

(Patent N° 01268480)

 

 

AF SHALLOW CORE SYSTEM is a continuous core drilling system for granular and cohesive rocks, specifically engineered for quick coring.

 

 AF SHALLOW CORE SYSTEM particularly suited when a continuous coring for detailed stratigraphy is needed and the use of a traditional drilling system is precluded by logistics or environ.

 

 

    AF SHALLOW CORE SYSTEM

is the only one coring system allowing 100% sample retrieving even in saturated loose sands!

 

 

AF SHALLOW CORE SYSTEM allows 100% recovery of continuous + 30ft long core, with low geotechnical parameters alteration, for stratigraphic, paleontologic, chemical or granulometric analysis etc..

 

 

The use of a specially designed and engineered textile liner allows an easy handling and storing of the core even in absence of any dedicated container, furthermore, the core is retrieved just by gravity: no special tool required!

 

 

 

 

 

CAMPI DI APPLICAZIONE:

  • geognostics

  • pollution moitoring

  • stratigraphy

  • agropedology

  • palinology

  • hidrogeological

  • hidrogeochemical studies etc...

 

AF SHALLOW CORE SYSTEM is composed by:

  • drilling string: ultra-light drilling pipes, coring bit, core sheathing head, sheath cartridges

  • gas hummer

  • recovery jack
