WOLVERHAMPTON CITY COUNCIL
Demolition Of Oxley Moor Bridge, WolverhamptonConnell Brothers Ltd (CBL) were appointed by Wolverhampton City Council to demolish a redundant railway bridge over Oxley Moor Road. The bridge was constructed of steel beams and decking and formerly carried two railway lines.
Oxley Moor Road is a busy main road between large residential areas and passes beneath the existing live railway lines which are 30 meters away from the redundant bridge. Where the road passes beneath the bridge the traffic is restricted to one way and is controlled by traffic lights. Due to the restricted access and Oxley Moor Road being a main thoroughfare a major consideration was the minimisation of disruption to traffic.
In order to carry out the works Oxley Moor Road was closed to all traffic. Access to the bridge was then made via an existing gate to the north and by clearing overgrown vegetation to allow excavators onto the old railway line. Once access had been achieved the excavators removed the ballast and other fill material from the bridge deck to expose the metal plates. These plates were supported by a system of beams that spanned off the main beams that spanned between the brick abutment walls.
The plates were then cut in pre-determined locations and openings formed in them to allow chains to pass through the plates and around the secondary support beams below.
Once the pre-cutting had been completed an excavator was positioned on timber Navi mats on Oxley Moor Road. Operatives then used oxy/propane cutting equipment to cut the top half of the steel sides into sections and these were lifted down by the excavator and placed directly into skips to be removed from site.
Once the sides had been removed the sections of deck plates and secondary beams were cut out and removed by the excavator. The lower half of the steel sides were then removed to leave the main beams spanning the road.
Once the sides had been sufficiently reduced in size they were cut through at each end and lowered to ground level and placed on timber Navi mats where operatives further size reduced them to enable them to be placed in skips for removal from the site.
Once all the steelwork had been removed repairs were carried out to the retained brick abutment walls and to the piers. Fencing was then erected on each side of the redundant railway and tied back to the piers to provide a safe barrier.
