Abstract

HERRAMIENTA DE PERFORACION PARA PERFORACION EN TIERRA SUELTA, TAL COMO CUANDO SE REFUERZAN LOS CIMIENTOS EN RELACION CON LA EDIFICACION. LA HERRAMIENTA DE PERFORACION CONSTA DE DOS PARTES Y TIENE UNA PIEZA DE TRANSICION CILINDRICA SUPERIOR (1), COINCIDIENDO SU EJE CENTRAL CON EL EJE GIRATORIO DE LA HERRAMIENTA DE PERFORACION, Y PROVISTA CON UN AGUJERO CILINDRICO CONCENTRICO (4), Y UNA PIEZA (2) DE UN ESCARIADOR INFERIOR PROVISTA CON UN EJE (3) DIRIGIDO HACIA ARRIBA PARA ENCAJAR DENTRPO DEL AGUJERO. EN LA POSICION OPERATIVA DEL EJE (3) ESTE ESTA COMPLETAMENTE INSERTADO DENTRO DEL AGUJERO (4) Y LA PIEZA DE TRANSICION (1) Y LA PIEZA ESCARIADORA (2) COOPERAN. LA POSICION DE EXTRACCION DEL EJE (3) ESTA PARCIALMENTE RETIRADO DEL AGUJERO (4) PARA PERMITIR QUE EL PERFORADOR (1,2) SEA SACADO A TRAVES DE UN TUBO DE ENVOLTURA O DE REVESTIMIENTO.
