I think they should do what Antic Pubs do, and and open it to customers now before it's finished.
More photos have been released:
Love this stuff
Yeah I saw some of these on the LBC website. I posted about it here.
Tunnel breakthrough to Canary Wharf station
The music's not even slightly over the top either.
It's amazing how rapidly it's all coming together when you consider the pace of change in other areas of large scale construction dogged by politics... eg. HS2, Wembley Stadium, Nuclear Power, SE Airport Capacity etc.
Just goes to show that when the only barrier is economic feasibility and a few compulsory purchase orders (RIP Astoria), these things can come together pretty damn quick.
It's not that quick, really. No trains through that tunnel till 2018.
I mean comparatively, considering the logistics, and tunnelling and track and shit being laid down it seems to be moving on with gusto since the govt gave it the green lit wheras HS2 seems to be moving at a snails pace due to the politicking of the nimbys and govt(s).
Wow. I had never considered the precision required with something like this before, but imagine having a machine that big, and digging a hole through the earth for however far it is, but having to be exactly at the right point at the other end.
I can't even manage to saw through a piece of wood in a straight line!
I remember going through the channel tunnel the very first time. I was on a train under the fucking sea
Bit overkill for my rare need to cut wood, but I'll look into it, cheers
I still have that I'm under the sea feeling everytime I go on it
not at all! I have a power saw with laser guide. You point the dot at the line ahead, which effectively drags the blade behind in a straight line.
Great stuff. I thought I was being clever but it turns out lasers on home tools are a thing.
Not GPS ?
Not underground, no. GPS is used to get an accurate position at access shafts and tunnel mouths. Then lasers are bounced down the tunnels with prisms to the boring machines.
Bit mean on the machines there. I find them quite interesting.
GPS relies on satellites, and needs line of slight with the sky/satellite - which is a bit difficult when your underground!
Thanks for letting us know about the pics ed! I enjoyed them!
and needs line of slight with the sky -
not always so been in dense woods but still pick up GPS, I thought about underground but how would a lasers go thru rock and earth. I see laser mouthed on wall for a level line working on a suspended ceiling.
I've heard you can earn 3k a week as a health and safety observer on these tunneling things, but its 12hr shifts and the crew all live underground during the week
I'd love to get down there with my camera
A bit of contrast:
Where's that geezer on here who sneaks into supposedly secure locations and takes amazing photos? Can we send him down there?
paolo <that one
e2a cough, alledgedly
