Dealing With Obstacles
The operator will invariably encounter a range of obstacles in a pipe. Each time the operator must decide
if the vehicle can safely pass or if there is risk of getting stuck. Common obstacles include but are not
limited to:
•
Crushed pipe
•
Sand
•
Rocks and/or debris
•
Roots
•
Intersecting service pipes
•
Animals and their nests
If the operator is unsure about pipe navigability, he or she should consult with the site supervisor before
moving forward.
Inspection Guidelines
The objective of an inspection is to obtain a recording of video and other data for review by the customer
or pipe owner. If a recording is lost, fails to record, or is of poor quality the inspection will likely have to be
re-
done at the operator’s expense. Therefore, it is in the operator’s best interest to verify vehicle
operation, video quality and recorder function before beginning each inspection.
A set of video overlay comments and data are usually required depending on the contract or client. Initial
comments will usually include the location, pipe number and date. During the inspection the contractor
may require certain pipe features or faults to be pointed out along with the distance from the pipe entry.
Conduct a complete inspection of pipe features and faults. For any feature or situation of interest, stop
the vehicle and make a complete video survey using the continuous pan feature of the camera.
Ultimately, the inspection is conducted for the benefit of the client who is reviewing the footage later on.
