Bridge 1, Broadway
A new Evesham side flange plate. |
The last of the
large new plates for the bottom flange of the upside outer girder were brought to
site this morning. The photo shows the first of these alongside the main beam to
which it is to be bolted. Another longer one is waiting to be dragged on top
before the two can be bolted to the visible flange angles. The burning gear is
on hand to cut out 3 small sections of the outer angle which have corroded away
to almost nothing from the original ½” thickness!! New ones will be welded in
and a cover plate fitted to act as a splice plate.
Broadway bridge continues to be in the hands of the fabricators, who are concentrating on the underside, for which scaffolding needs to be in place.
Bridge 5, Little Buckland
The main
activity yesterday was the pouring of the second lift of concrete behind the
Broadway end abutment. This involved pumping in about 4 loads of
concrete, which unfortunately happened before and after we were on site - we can't be there 24hrs a day! Below are
a couple of shots of the overall pour, and another with one of the men measuring up
for the last load.
In the
background you can see some the Severn Trent workers that have come to fix a leak – it
turned out to be a leaking collar joint, over 1M deep and some way from where the contractor's machines had been travelling! Not our fault then.
This seems to be the second time that the original contractors didn't let the brickwork harden properly, before moving on to the next stage. The other occasion we know about was at Stanway viaduct, which suffered a partial collapse as it was being built. There, they took away the shuttering under the arches too soon, while a heavy crane was also parked on top. Three arches collapsed as a result!
Main steel beam on edge of padstone, with new extension fitted to bolt into the concrete. The padstone overhangs the brickwork. |
