New solutions for trenchless pipe installation from TRACTO-TECHNIK

The IFAT exhibition in Munich has turned out very satisfactory for TRACTO-TECHNIK. The trade visitors were especially interested in the TT boring systems for the renewal/rehabilitation of pipelines.
 
These include the pipe bursting technology with its numerous application variants for pipe renewal as well as the auger boring technology for the new installation of pipes out of manholes.
 
It was news to many visitors that the GRUNDOMAT soil displacement hammer can be applied for renewing property service connections.





But the centre of attention was the new TT-PipeREDUCER. The TT pipe reduction method allows for a PE pipe string with reduced diameter to adapt "close-fit" inside the old pipe wall whilst being pulled through the host pipe.
 
A further highlight was the GRUNDOPIT Keyhole technology. A keyhole is a small, circular construction pit that is dug out using a suction excavator with minimal surface disruption. For works in the underground infrastructure the fully automatic bore rig GRUNDOPIT K is mounted inside the keyhole. That way, property service connections of all kinds can be established in a cost-efficient and environmentally sound manner.  The keyhole itself can also be used for the inspection of pipelines and for repairing or renovating existing gas and water pipes. Network operators, customers and road authorities have recognized the keyhole technology’s benefits due to remarkable cost savings and distinctively reduced installation times
 
The iomplementation of the trenchless keyhole technology in practice was supported by the DVGW (German Assiaciation for Gas and Water) by means of y research project including pilot jobsites as well as a series of national and international expert lectures. The expected cost advantages compared to open trench methods have been proved at numerous test jobsites.
 
Currently TRACTO-TECHNIK provides a complete portfolio of machines and equipment for the renovation, renewal and new installation of supply and sewage pipelines from the main pipe up to the service connection in the house.
