AF SHALLOW CORE SYSTEM
(Patent N° 01268480)

AF SHALLOW CORE SYSTEM
Continuous core drilling system for granular and coesive rocks, specifically engineered for quick coring. 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.

The only coring sistem allowing 100% sample retriving even in saturated loose sands!

AF SHALLOW CORE SYSTEM is composed by:
Drilling string: ultralight drilling pipes, coring bit, core sheating head, sheath cartridges
Gas hummer
Recovery jack		 AF SHALLOW CORE SYSTEM
Allows 100% recovery of continuous +30ft long core, with low geotechnical parameters alteration, for stratigraphic, paleontologic, chemical or granulometric analysys 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 retrived just by gravity: no special tool required!


USES
Geognostics, pollution moitoring, stratigraphy, agropedology, palinology, hidrogeological and hidrogeochemical studies etc.
AF SHALLOW CORE SYSTEM components:

DRILLING STRING
Sheathing head: maximum thickness, including enlarger ring, only 9 mm (outer radius minus core radius); just two parts easily assembled (sheath holder and coring bit). Fout head= 63 mm Core diameter= 38mm
