Scandinavian No-Dig T47 Bursting Rig

This project was carried out in the small village of Kilmichael, which despite its size is extremely busy with local traffic. The water mains pipe needed bursting and the new pipe pulling through.

The Challenge

The location proved to be a significant challenge. Part of the mains ran under a narrow road directly outside the Glassary Primary School, which meant that operatives were working with limited space in small pits with traffic passing to the side. The sewer main was also located above the water pipe and electric cables and BT fibre optic cables also running very close to the water pipe. This made accuracy extremely important. Furthermore, there were some large bends in the existing pipe and it was anticipated that they would prove difficult to burst.

The Solution

PSS HIRE recommended the use of the T47 Scandinavian No Dig Pipe Bursting Rig as an alternative to the traditional open cut method. It was envisaged that this would enable the project to be completed quickly with minimal disruption to traffic and a reduction in the impact to the surrounding environment. The T47 Pipe Burster has 47 tonnes of static pull-back power and is capable of replacing existing pipes from 90 mm up to 315 mm diameter. Narrow and lightweight in design, it fits between even the closest parallel installations.

The Solution was to hire the Scandinavian No-Dig T47 Pipe Burster from PSS HIRE due to its narrow design and 47 tonnes of static pulling power.

The Results

The use of the T47 Pipe Burster brought huge benefits to this project in terms of time and cost efficiencies and all challenges were overcome with ease. Corrie Construction were able to burst and pull through 300 m of pipe every two days. The team perfected the process for bursting; instead of detaching each rod as it pulled through the machine, they were able to push through the existing pipe to the next pit where they were re-attached to the burster. By using this method, hours and hours were saved. This project was deemed to be a huge success and there were absolutely no complaints from local residents about disruption.
