WHAT CAN CCTV SEE THAT YOU CAN'T?
The power of remote visual inspection
PICA recently completed an interesting job using its brand new "Mini-Lite" CCTV System. The challenge was to determine if there was a blockage or a collapsed portion of a PVC pipe that was installed to carry electrical cables and sensors through a concrete bridge.
When the contractor came to install the cables, they were unable to blow a string through the pipe to pull-in the cable. The bridge and access is shown below:
The Mini-Lite System used was able to negotiate the 3" PVC pipe for several hundred feet before discovering that there was a split in the pipe, through which cement has penetrated, forming a plug. This was confirmed from both sides, allowing the contractor to formulate an action plan to remove it or bypass that conduit.
The Pan/Tilt/Zoom functions are all built-in on the Mini-Lite, allowing unprecedented images to be recorded for the report. All images are seen real-time on the portable display as shown above.
The cement plug is seen in the screen capture above.
