Abstract

Viene descritto un utensile (1) di scavo da roccia per la realizzazione di pali trivellati a grande diametro, pozzi di ventilazione ed altre opere di scavo simili, atto ad essere montato in modo svincolabile sull'estremità inferiore di una batteria di aste (20) di un impianto di trivellazione (30).L'utensile (1) è costituito da un contenitore (2) di forma sostanzialmente cilindrica o debolmente tronco-conica provvisto inferiormente di una pluralità di utensili di taglio o cutters (10) atta a frantumare la roccia. Sullo stesso utensile (1) sono inoltre previsti:- mezzi di supporto (3) atti a trattenere in modo svincolabile una pluralità di elementi modulari (14) che concorrono a formare una zavorra (13); e - mezzi di raccolta (9), posti in prossimità degli utensili di taglio (10), atti a convogliare all'interno del contenitore (2) i frammenti di roccia attraverso apposite aperture (9) sul fondo del contenitore (2).
