The technology of Pipe bursting was popularised in the late 1970’s and early 1980’s when TRACTO developed a machine, the pneumatic GRUNDOCRACK, at the request of then nationally owned utility British Gas and Severn Trent Water. The objective was to facilitate the installation of replacement water pipes using trenchless methods to minimise disturbance to the surroundings and to save money by working more quickly and efficiently with less disturbance to the customer. The process was further developed to include the hydraulic GRUNDOBURST ladder rod system which can burst pipes from 2” to 32” and install up to 900mm HDPE pipe.
In the two-week run up to No Dig Live, trenchless technology supplier, TRACTO UK, is launching a competition to find the UK’s oldest working GRUNDOMAT mole.
Difficult ground conditions called for a specialist solution when new PE pipes for potable water services had to be installed underneath two, 10-metre road crossings in the grounds of the UK’s ultimate music festival at Worthy Farm.
A TRACTO Mini Olymp GRUNDORAM pipe rammer was recently deployed to a site to ram a 325mm steel casing under the concrete foundations of a new production plant. The casing was required to host a 225mm HDPE conduit to carry away rainwater from the downpipes of the roof.
A job awarded to FCH Construction by Scottish Water involved the connection of water to a detached residential property in Inchture. With their knowledge and experience of trenchless technology, FCH Construction liaised with the team at TRACTO, who recommended the PS60 with its ample capacity for the short water crossing.
Budleigh Salterton is located on the English Jurassic Coast: a picturesque UNESCO World Heritage Site famous for its extraordinary rocks, fossils and landforms. and a year-round tourist destination. When a 100 year old rainwater/sewage pipe needed to be replaced, a GRUNDORAM Goliath played a key role in its success.
The TRACTO GRUNDOPIT PS40 Mini HDD rig was the star turn at leading leisure park, Chessington World of Adventures, recently when it was craned into place to complete the underground installation of two x 110mm drainage pipes.
The GRUNDOMAT soil displacement hammer is ideal for the quick and gentle construction of trenchless house connections. In the Bolivian city of Cochabamba it contributed to the improvement of the drinking water supply, which is characterised by water scarcity and a dilapidated conduits. The impact mole was used to build around 1,000 new house connections as part of the inner-city drinking water network rehabilitation.
Installing pipelines in the Eastern Alps to use natural spring water from the Glingabrunnen spring - that was the enormous and demanding challenge in the Brandnertal valley: but with foresight, sure instinct and the steerable HDD drilling rig GRUNDODRILL 18ACS with rock drilling equipment, the installation succeeded without any problems and above all: trenchless.
How do you stop water loss through leaks in old pipe systems without major environmental impacts and restrictions? The answer: with trenchless technology, or more precisely the pipe bursting method.
Narrow mountain paths, rocky ground at 2,400 m above sea level on Muottas Muragl: An old drinking water pipeline for the hotel on the summit had to be renewed, and the impassable terrain in the Engadine presented a very special challenge. For the work in the Swiss mountains, only a trenchless solution came into question: The dynamic pipe bursting method with GRUNDOCRACK.
The GRUNDOPIT PS60 made it possible in the spa town of Cochem on the Moselle river to do what would have been unthinkable using conventional methods - install a new water pipeline through a densely built-up steep slope, in the shortest possible time.
Installing new house connections for green electricity under a busy street in the historic town centre of Landsberg am Lech - that was the task ahead. In this case, the medieval city centre only allowed one solution and direction: trenchless under the street.
In order to renew a particularly badly damaged water pipeline in the Moroccan capital Rabat, trenchless construction proved to be the only alternative. For NODIG technology, the work in the historic Takadoum district did not present an insurmountable challenge.
Probably the most northerly deployment of a HDD drilling rig took place high up in the north of Spitsbergen: The numerous locally based, internationally networked research stations need the fibre optic cable expansion for more bandwidth.
Almost half of the northern German island of Sylt is under nature conservation. Replacing the above-ground and therefore vulnerable, old overhead lines with underground cables without risking major impacts on the sensitive local ecosystem was therefore a challenging task.
