Pipe bursting is a safe and approved method for replacing pipes underground in the existing route which has been in use all over the world for the past 30 years. Old long or short pipes up to ND 1,200 of almost any material (plastic, metal, GFRP or stoneware) can be replaced with new pipes from the coil or pipe segments having identical, smaller or larger diameters. Daily capacities of 150 - 300 m are possible. Different models allow for application out of pits and/or manholes into pits and/or manholes. The result is a new pipe with a service life of 80 - 100 years in perfect static conditions at 50 percent cost saving compared to open trench methods.
There are two different pipe bursting methods for trenchless pipe renewal. The dynamic pipe cracking technique is favorable for replacing gas or sewer pipes made of brittle materials and especially suitable for manhole to manhole applications. The static pipe bursting method is favorable for replacing all kinds of utility pipes made of any brittle or ductile material. Pipes made of PE, GFRP or pipes with inner lining can be cut as well.
Static pipe bursting systems like GRUNDOBURST make pipe replacement even along slight bends quick and easy. In addition to completely renewing pipes using the static pipe bursting method, the QuickLock rods along with a special latching finger allow for pipe repair and renovation. The main decisive factors for choosing the appropriate method are degree and type of damage, sustainability of the method and the resulting rehabilitation cost. A wide range of bespoke accessories enables safe and trouble-free execution of the methods described in the following.
Pipe bursting systems have proven their reliability and versatility throughout the past decades. They are the perfect choice for the trenchless rehabilitation of gas, water, sewage lines in sensitive grounds or near neighboring pipes, cables or close to buildings. The following practical examples document that rigs like GRUNDOBURST provide profitable and sustainable solutions to remedy the problem of water loss and/or inadequate pipe capacity with ageing urban networks.
As part of the renovation of the water supply system at Miodowa street in the historic city of Warsaw an old steel pipe was replaced with a cast iron pipe of the same diameter. A major requirement was minimal interference of the traffic along the busy Miodowa road, so the project called for a trenchless replacement method. The compact GRUNDOBURST 800G was chosen as the ideal bursting rig for this project. All work associated with the renovation took place with constant foot traffic and cycling. Thanks to their fast click-shut connection the QuickLock rods were pushed through this 100 m section in only 45 minutes.
