For the past 30 years pipe bursting has been a worldwide approved method for the renewal of pressure and gradient pipes with new pipe of equal or larger diameter. In the process, the old pipe is replaced by a new pipe of equal or larger diameter. Using static pipe bursting with GRUNDOBURST, lengths of up to 150 m can be achieved in both directions from out of a machine pit.
With the powerful and robust GRUNDOBURST hydraulic bursting rigs, damaged pipes up to Ø 1,200 mm (circular and oval profiles) can be replaced without trenches. First, the rig pushes the bursting rods through the old pipe. The specially developed QuickLock rods are not screwed together but simply and firmly connected with a click-shut coupling. This considerably simplifies handling on the job site. Also slight bends can be driven with the QuickLock rods. Once the cutting tool and the new pipe have been attached, the pulling-in process begins. The GRUNDOBURST rigs develop a pulling force of 40 t to 250 t.
In addition to the complete renewal of pipes using static pipe bursting, the versatile GRUNDOBURST hydraulic bursting rigs can also be used for the partial repair and renovation of pipes. An extensive choice of static pipe bursting equipment and accessories enables these rehabilitation methods to be carried out safely and trouble-free.
