It's worse than that

Tuesday 3 September 

Contractors were in at Culvert 45A at Wyman's Brook in Cheltenham to remove the fallen trees to allow the structural inspection to be conducted. The problem now being that the damage to the wing wall caused by the ash tree is clearly visible and it's not looking good.

Is it worth counting the rings to see how long the ash has been growing, the estimate is around 4o years.

Thursday 5 September 

Back to sunny Stanton with more bits done on the down side inlet channel. The final bit of the concrete base for the channel was laid, to do this the stream water had to be pumped around that section and the down side cess dribble needed to be piped over it as well. In the middle of all this, Michael was working away on the outside wall.

Despite the channel still being a bit wet the concrete was laid, then a temporary bypass pipe was fitted in an attempt to keep the concrete dry until it sets.

In between things, the down side cess headwall was unwrapped and landscaped, that's another job ticked off the list.

Under the bridge a surprise awaits the Saturday team... 

New gully for the centre of the track 

The only gully our supplier had was a 750mm deep version, this may take a bit of digging in 😰 The farmer removed the straw today so we may have a window of opportunity to get this sunk into the roadway.

  1. How do you intend to remove the stump of the ash tree without doing much more damage to the wing wall?

    1. Not sure if we will remove it yet, as it's beyond the running line we might leave it for a while and see how stable it is now the tree has gone. Otherwise it's dismantle the wall and rebuild :-(

    2. I hate to think how far those ash roots go back into the embankment. Not an easy job - good luck if you attempt it!

  2. I suspect that if you leave the Ash without cutting the roots off, it will continue to grow.
