The third bridge switch of the past four weeks took space below the Coventry to Leamington Spa railway in Warwickshire.
Balfour Beatty Vinci, the HS2 foremost contractor for the Birmingham stop of HS2 section one, has been building structures offline, then transferring them into space to minimise disruption to present rail companies.
The most fresh switch saw a 5,600-tonne field, measuring 22 metres lengthy by 11 metres wide, moved 47 metres into space.
While old heavyshift operations admire been performed by Mammoet the usage of self-propelled modular transporters (SPMTs), this one become once done by Vinci firm Freyssinet the usage of 5 3.8-tonne hydraulic jacks to push it all the plan in which thru a sliding surface.

From the open of blockade on Saturday twenty ninth July, 113 metres of the present rail monitor and 188 rail sleepers had been eradicated by the 250-solid crew. Then 15,000 cubic metres of ground, alongside side laborious sandstone area materials, become once excavated to create the house for the bridge to be moved into.
Enthralling at around 9 metres per hour, it took 5 and a half hours to push the structure into space. It become once completed at 03.30 hrs on Monday thirty first July, 27 hours earlier than agenda.
The group is now backfilling around the structure and striking the rail monitor again in space above it, ready for the railway to be re-opened at 08.30 on Sunday sixth August.
On 17th July, a 6,200-tonne bridge become once moved into space by Mammoet an 840-wheeled SPMT at Fulfen Wood conclude to Lichfield below the West Flee Major Line. [See our previous report here.]
On 28th July, a 2,600-tonne bridge become once also driven below the present South Staffordshire freight railway line at nearby Streethay the usage of the the same manner however with fewer axle lines required.
Balfour Beatty Vinci project supervisor Shamus Banaghan talked about: “Over the final two and a half years thru build pattern to implementation, now we admire remained serious about delivering this serious bridge switch all the plan thru the fixed Network Rail blockade. I would favor to extend my thanks to all people who has contributed to us achieving this most modern feat of engineering earlier than agenda.”
