Core Barrel Stabilizer

Abstract

A core barrel stabilizer that offers a simple solution in creating an initial drilling kerf in conjunction with a hollow core barrel for drilling large diameter holes into the earth for a plethora of construction needs. The core barrel stabilizer includes a centering rod for keeping the core barrel stabilizer and hollow core barrel centered during drilling the initial perimeter kerf, an eyelet hook for easily maneuvering the core barrel stabilizer between drill holes and transportation, and an inner barrel used to rest the inner wall of the hollow core barrel against during drilling to ensure the drilling kerf can be started.

         3 : A removable core barrel stabilizer ( 1 ) for assisting a core barrel ( 2 ) in the initial creation of a drilling kerf ( 10 ) in an even or uneven ground ( 3 ) during the start of drilling with a core barrel ( 2 ), whereas a rigid centering rod ( 4 ) is connected in the center of a cylindrical inner barrel ( 6 ), in which, the centering rod ( 4 ) gets positioned concentric into a ground pilot hole ( 9 ) by means of an eyelet hook ( 5 ), and the inner barrel ( 6 ) fits snug on the inside of the core barrel ( 2 ), after the core barrel ( 2 ) is placed over the inner barrel ( 6 ), in order to drill into a ground ( 3 ) surface concentrically.
