Poundfield Precast of Ipswich in Suffolk has recently supplied a set of eight reinforced concrete bridge components for the re-decking of a narrow, rural road bridge crossing the river Lark at Flempton Lock near Bury St. Edmunds.
The concrete bridge components, consisting of two sill beams, four intermediate deck beams and two edge beams, have been supplied to Suffolk Highways which also produced the necessary design drawings.
The new deck utilises the existing brick abutments with a sill beam installed on each side to which are bolted the intermediate and side beams with an intervening rubber strip.
Because of the presence of overhead power cables, a crane could not be used for the installation so the concrete bridge beams had to be lowered into position using a 30 tonne excavator equipped with height and slew restrictors and standing safely away from the abutment. Once all the beams were in place, lengths of rebar were inserted between each and attached to the exposed loops of rebar of each section prior to the gaps being filled with concrete.
Commenting on the project, Danny Cattermole, Structures Works manager at Suffolk Highways, said: “We have used Poundfield for many jobs like this over the years as we always strive to use local suppliers whenever possible. This partnership has resulted in an excellent working relationship with the company and it is very easy for us to visit them if we need to sort out any technical issues or see our components being cast if necessary.”
Our bespoke precast concrete department have a wealth of experience with bridge beams, designed to your exact requirements, on hand throughout the project.
