Define Equipments and tools required for under water Inspection of Bridge?

Since the underwater inspection of stone masonry substructures involve only a cursory inspection of the joints between stones and the general condition of the wall and its foundation, only a few tools are required. A sounding hammer is usually employed to assess the voids below the surface. A ruler may be used to determine the width and depth of cracks and open joints, as well as the size of missing stones or pieces of stone. A length of small diameter rebars or other appropriate probe can be utilized to test the voids in the fill behind or below the wall.

A Plexiglas slate and a grease pencil are utilized underwater to record any type of pertinent information, or the information is communicated to topside personnel via hardwire. Small hand tools, like wire brushes and scrapers are as well helpful to clear off cracks and joints.
