Robotic Cutting Technology and its Applications in Pipeline Rehabilitation  


Robotic cutters are considered to be extremely essential weapons in the arsenal of any drainage specialist. This advanced technology tool is not only highly effective in eliminating obstructions, but also helps avoid disruptive and expensive excavation because it is possible to control robotic cutters remotely from above ground. Robotic cutting technology offers a number of important advantages compared to traditional methodologies.   

Robotic cutters are available in many different models, including pneumatic, hydraulic, electric, and battery. These tools are used for a wide spectrum of drainage applications, from removal of solid materials from a pipe to pipeline rehabilitation. Air driven and hydraulic driven systems are the two methods by which the process of robotic cutting is carried out. The hydraulic driven system can be used for all types of materials. On the other hand, the air driven systems performs well in certain types of materials. This is because compared to a hydraulic system, an air driven system can generate considerably less torque at the point of cutting. Though hydraulic systems are more expensive than its counterpart, their versatility and efficiency pays off for the high investment.  

Applications of Robotic Cutters  

Some of the most common applications of robotic cutting are summarised below.  

  • Opening lateral connections: Branch pipes connecting a building property to the main sewer are referred to as lateral connections.  One of the most effective ways to rehabilitate a defective drain is to insert a cured in place pipe (CIPP).  Remote-access no-dig technology is used to install a liner in the drain, and new pipe is created within the existing one. Lateral connections joining the main sewer get covered by the new lining, and must be opened for reinstating the drainage system completely. Modern remote cutters are used to cut away the hardened liner at points of intersection between the main pipe and each of the laterals.  
  • Robotic cutters are also used extensively for the removal many different types of obstructions from sewage and pipelines. When problems are experienced on site because of reoccurring blockage, the same can be found out during maintenance by carrying out CCTV survey.  
  • Another common problem in pipeline and drainage systems, root ingress can severely affect the drain’s structural identity. It may result in a potential blockage by acting as a screen and catching debris. Robotic cutters are the perfect tools for getting rid of tree roots that are extremely difficult to be dug out manually.   
  • During construction work, cement, tile slurry, concrete, and other construction materials often make their way into the drain and sewer network. It is also common for homeowners to find metal foundation spikes, wooden fencing stakes, cables and other types of discarded detritus in their drain. Robotic cutting allows all these materials to be ground or cut into smaller pieces and vacuumed out by water jets through the nearest manhole chamber.
