Time for the acid test at Stanton

Saturday 3 August 

Little did we realise when we set off for Stanton this morning that our work would have undergone full user testing in our absence. From the inception of the project we knew that harvest traffic would be using the bridge around the end of July, hence the push to get the up side finished and the track passable in time. The surprise we got this morning was in the shape of a combine harvester sitting the field on the down side of the track. That could only mean one thing, harvest traffic had been using the bridge. A quick inspection showed that the structure had held up well, this is despite the fact that the concrete backfill on the up side hasn't had the requisite 28 day curing period to reach its 30 Newton strength.  

The focus today was on finishing the brickwork on the up side and starting it on the down side. The footings for the down side north wall were concreted as well.

Late morning saw the arrival of the farmer with his grain trailer, did it fit through the bridge? only just. There was about 50 mm between the top of the exhaust and the bridge deck.

After doing the first row of blocks, Roger went over to the up side to finish off fitting the taper bricks in the arch.

On the down side the excavation and shuttering had been completed for concreting the footing for the north wall extension.

After lunch the concreting started in earnest.

The afternoon grain haulage was with a slightly smaller tractor and trailer, unusually for harvest, the farmer was driving the combine and then taking the grain away himself.

  1. Too right, absolutely ****** marvellous. Its not just impressive work and the professional brick laying etc; its the great blog with helpful detail narrative and photographs. There's also no doubt this is vital work to maintain the integrity of the embankment and enable rainful (and melting snow) to drain away ASAP!
