Pre-stressed Concrete box beams for Haxton Bridge, Wiltshire
6th October, 2011 by Gillian MurtaghRingway Construction appointed Shay Murtagh Precast their manufacturer for the Haxton Bridge Project. We manufactured the precast elements which assembled consisted of nine internal solid pre-stressed box beams and two outer pre-stressed edge beams which were 15.4m long. The internal beams were 495mm wide by 700mm deep and weighed 11.4T.
The edge beams incorporated a second stage factory cast pour to provide the required external profile. This increased the edge beam width to 773mm and extended to 415mm beyond the beam ends. The edge beam weighed 19.9T including the second stage concrete pour. Projecting link reinforcement was provided along the sides of the beams to enable an insitu shear key to be poured on site.
Delivery was completed by the Shay Murtagh Precast logistics team and the Wiltshire project was completed on schedule requested by Client.
