QUB Engineers Develop World's Longest 'Flat Pack' Bridge
Civil Engineers at Queen’s University Belfast have collaborated on a project to develop the world’s longest 'flat pack' arch bridge.
Developed through a partnership with pre-cast concrete specialists Macrete Ireland, the bridge is based on the 'FlexiArch' system and is unique in that it will be transported to site in flat-pack form. When lifted, it will transform under gravity into an arch.
The bridge is due to be installed near Portsmouth in coming months and will span 16 metres (53 feet) over the Wallington River in Waterlooville, Hampshire. Made up of 17 units (1m wide) of pre-cast concrete, each weighing 16 tons, the bridge will take less than a day to install using a 200-300 ton crane in association with a lifting beam also designed and built in Northern Ireland.
There are over 50 FlexiArch bridges now in the UK and Ireland, including the three footbridges in parkland surrounding Newtownabbey Council building.
Professor Adrian Long, from the School of Planning, Architecture and Civil Engineering at Queen’s University, who patented the FlexiArch concept in 2004, said: "This is a real milestone which has been reached as a result of the hard work, effective collaboration and the combined expertise of the Queen’s and Macrete team. We are delighted with this latest development and of how successful the FlexiArch system has become. Over 50 FlexiArch bridges have now been installed in the UK and Ireland where it has been found to be even more versatile than anticipated."
