What Does Lateral Launch Camera Mean?
A lateral launch camera is a video inspection device used to inspect lateral lines branching out from the main line. Sometimes, it is also used to inspect pipelines to ensure that gas lines have not cross bored into a sewer line.
Trenchless rehabilitation methods require that the pipelines to be rehabilitated are inspected for damage to minimize cost by targeting the point of repair.
Trenchlesspedia Explains Lateral Launch Camera
Lateral launch cameras are capable of inspecting mainline and laterals simultaneously and can inspect mainlines to a distance up to 1,000-feet from the entry point and laterals up to 150-feet from the mainline. The streamed video can be seen in real time on computers connected to the camera. It also has pan and tilt options to inspect the pipelines from different angles and can be maneuvered forward and reverse with the help of the crawler on which it is mounted.
It is especially used when trenchless operation such as horizontal directional drilling (HDD) are to be employed in the vicinity of a pipeline to inspect if any laterals are prone to cross boring or any cross bore has previously occurred.
