Werrington grade separation updates

If you click on the icons in the bottom right, the options appear in German!

Right... interesting... so they've obviously contracted the production of the video to a German company, so naturally they used the train images with which they are familiar?

That'll be more contig piles for the bridge then.

Contig?

 

[DelW]

Contig?

Contiguous piles, i.e. bored concrete piles just touching each other to form a retaining wall. (If they overlap they're called secant piles).

Popped out for a walk this evening. Admittedly only with my phone, and it was 9.30pm, so the light was terrible. Not much has changed since the last pictures just up-thread.

What do they do when they get to the section under the bridge where the pilling machine can't fit under?

I've asked the same question on another forum. I'll let you know if I get an answer.

Many thanks for the informative reply. Is there a more specific explanation as to how the piling under the Cock Lane footbridge will be done given the reduced headroom under the new bridge?

@Crun had also linked to that himself back in Post #330! Thought it seemed familiar...

I wonder if they will do the same as under the A15 and use an auger to drill down to create cast columns?

 

[Ploughman]

Can they use shorter piling rigs or shorter piles and weld on extensions as they get driven in?

 

[DelW]

Can they use shorter piling rigs or shorter piles and weld on extensions as they get driven in?

Both are feasible (I've used such techniques to work under HV power lines, for example), but both add considerably to the time and cost of installation.

 

[Crun]

I've just learnt that the tunnel/portal installation under the main line has been put back from September until next February. This is because of the risk assessment for the tunnelling activity which required close working between more than one individual, i.e, less than 2 m.

How, when and why did a burrowing junction become a dive-under?
