Abstract
A borehole inspection device and method of using the same to measure the condition of the bottom extent of a borehole, the system having a head unit assembly with top and bottom sides and including at least one downwardly extending force sensor configured to measure a reaction force applied to the at least one sensor as it engages a bottom extent of the borehole, the inspection device being configured to be lowered into a borehole and to bring the sensor(s) into contact with the bottom extent wherein continued downward movement of the head unit creates the reaction force on the sensor(s) to determine at least one of a location of an associated debris layer, a bearing capacity of the associated debris layer, the thickness of the associated debris layer, the location of an associated bearing layer and/or the bearing capacity of the associated bearing layer.
