Apparatus for testing an elongated conduit using an internally applied non destructive wall deformation
First Claim
1. Apparatus for conducting non-destructive testing of an elongated conduit that includes:
- a carriage for movement along said conduit,a test bar having opposing ends, said test bar rotatably mounted on said carriage for movement in a plane perpendicular to a central longitudinal axis of said conduit,means for extending both ends of said bar into contact against an inner wall of said conduit to deform said wall,sensing means for measuring the amount of deformation produced by said bar and providing an output data signal indicative thereof, andmemory means for storing the data signal information.

Abstract
A method for non-destructive evaluation of a conduit, gallery or similar structure as shown which involves mechanical tests using an apparatus for applying forces to the walls of the structure in one or two opposite directions and measuring the displacement and or deformation resulting from the application of the forces. The applied forces and the displacements are measured, received, processed and stored in memory for further processing analysis and diagnosis to determine the condition of the structure over the length evaluated. A suitable expert computer system is utilized to establish the overall condition of the structure and classify the structure into zones of risk for maintenance and or repair.
