Tunneling Guidance Systems
Pipe Jacking alignment accuracy is managed by assessing a laser target bolt’s position on the cutter head, at the centerline of the pipe. The laser is initiated from the pipe laser in the Laser Light Stand behind the jacking frame or pump unit in the launch shaft.
To check the alignment between haul unit transport cycles, the TBM or EBS operator lowers the conveyor to expose the target bolt laser beam. Frequent laser checks will result in fewer steering adjustments. Note, TBM and EBS roll is adjusted by engaging the torque/dirt wings.
The Laser Light Stand features an adjustable frame to position the laser down the centerline of the pipe. The laser box assembly is lockable to prevent tampering with the laser when not in operation.
Akkerman inventories a GEO VL‐70/‐80 Automatic Drifting Laser for our customers’ convenience, suitable for extended length straight tunnels, depending on the tunnel’s ambient conditions.
For proper laser system operation and installation, please refer to the manufacturer’s recommendations.
FEATURES:
- Adjustable Laser Light Stand includes a laser box and stakes to position the laser sight down the tunnel centerline for TBM/EBS operator viewing.
- Assembly includes a laser, positioning device, battery connector, and transport case.
Testimonials
With its purchase of an Akkerman Model 5000 pump unit, skid base, and WM72C wheel machine in 2006, Northeast Remsco began its partnership with Akkerman that has resulted in its successful completion of many trenchless projects over the ensuing years using conventional wheeled machines as well as a variety of pilot tube equipment. I call it a partnership because the Akkerman team provides advice on the best choice of trenchless equipment for a project as well as how best to overcome jobsite obstacles when they arise, as they inevitably do. From their sales staff to their factory support team, Akkerman employees work with us to get the most we can from the equipment and to get the jobs done safely. They are a pleasure to work with!
