With all the innovations for inspection and rehabilitating existing infrastructure, Mar-Tech is dedicated to learning all about emerging technologies. The RST helix Advanced Manhole Survey System Mar-Tech uses is the first of it’s kind in Canada and allows for detailed computer inspection of manholes and other interior chambers.
Inspection of a deteriorating manhole is instrumental in planning for it’s rehabilitation. Manholes often are replaced during open cut pipe installs, but for lining purposes, a more creative way of manhole rehabilitation takes place. After a thorough inspection, all deficiencies must be repaired, including ladder rungs and broken or missing sections. Once the structure is sound various methods of resurfacing or lining the manhole can take place.
Did you know that a 6 meter deep manhole has twice as much surface area compared to a 30 meter section of 200mm pipe? That’s why smart cities around the world have made manhole inspection a critical part of their infrastructure management. But inspecting manholes using traditional methods isn’t an easy task.
Manhole inspections need to be safe, detailed and fast. An above-ground visual inspection is safe and fast, but not detailed. Entering the manhole results in a more detailed inspection, but it’s not safe nor fast. Pole cams have helped speed up inspections and they keep workers safe, but often critical information is missing.
Introducing the Helix advanced manhole survey system. With the Helix your crews can survey 40+ manholes each day with an unprecedented level of detail. Because the system has six high resolution cameras capturing every surface, you’ll never miss an observation. Active 3D cameras locate hundreds of thousands of individual points within the manhole so that accurate measurements can be taken using software in the office. Best of all, workers are able to stay safely above ground without sacrificing the level of detail necessary to make critical engineering decisions.
