My
name is Colin Furze and i am digging a secret underground tunnel from my shed to my house
and then hopefully to my underground bunker at the bottom of my garden. Now so far we
have dug nearly four meters down and we have tunneled nearly six and a half meters across
but we're not quite at the house yet, and we're nowhere near the bunker. But what we
do want to do is kind of finish this bit off and make it safe. We don't want to be seeing
rock. We don't want all these uneven floors. No, we want it to look perfect like the entrance
to my underground bunker. So we've got to build a tunnel within this tunnel and surround
it in concrete. That's what this video is about. Hope you enjoy... SUBSCRIBE!!
It's a lovely thing to do! Enjoy the ride!
okie doke that's got the first bit down. Now this bit that we've plasma cut out in the
middle, this is so when the concrete comes down the side, if it doesn't quite sink under
it properly, because it didn't do in the bunker, we can put our arm under and kind of help
scoop it along.
Or of course we could just fill it up from the middle here and then push it all out so
it's nice and solid. Now to keep it level we've basically welded these little tags here
on our supporting frame, and then we put little posts underneath it to give it a little bit
more support. We've had to concentrate on trying to get the thing in line with the hole
at the top and our hole that we've dug isn't quite straight, but i can live with that.
So next bit's going to come down, we've got some little tabs welded on here that it can
sit onto So get that bit out and then just, just keep doing it basically!
Right got two bits of floor down now and we put this 50 mil box section here, basically
we put kingspan insulation in between this and then the floorboards over the top of it.
A little bit of insulation keeps it nice and toasty. So that's done that. The third one's
ready to go down and then we'll put a fourth one down, and then we'll start putting some
walls up and hopefully the dusty jobs are nearly over with. I got absolutely covered
in it yesterday.
Here we are. It's a new day people, we've had a dust down, we're a bit clearer. Right
floor is down, floor is level, floor is done. There's a little extra feature look over here...
I've put this little extra bit in, because we're going to house our hydraulic pump there,
so we can basically be in here all the time and then when we want to do the next bit,
we're not dragging it around on a piece of wood like we were last time. It's all plumbed
in the hydraulic lines and can kind of run under the carpe, then we can
get on with it. Right next up, exciting part! Put some walls up, cut some noggins and just
make it feel a little bit more like a tunnel. Colin how can this not feel like a tunnel
now?! If anything this is more tunnel like because you can see rock, shut up, just shut
up and get on with it!
Got a bit of wall! okay that's got one side up. But one advantage we have got with down here,
is because we've got this steel frame, we've welded some tabs like to the frame and to
the back of the wall. So the whole thing is like completely solid even though it's just
fixed down the bottom here. So next up, get another load of sheets down for the other
side, and then start thinking about curves and the bit that goes up to the workshop.
boom!
okay both sides of the walls are all done. We've got our little fireplace dog kennel
area down here where we're going to sit the pump. Now we've got to plasma cut the top
edge of this so it's all nice and straight, so we can now sink the arches onto the top
and that created so much smoke...
we've lost another budgie! Right next bit we've got to do the sides up to the surface.
So of course we've took the steps out, i'm still down here, we're struggling to lift
it out. I really have worked myself into a bit of a hole!
whey! Starting to look pretty cool now. So we've got the shaft steel up, we've plasma
cutted the arch out.
now all we need to do is uh slip roll loads of support, bend the steel around, like weld
it all up, get it all sorted and then we're kind of nearly there. It's just, it's just
connecting the bit up there to the shed floor, and then we're done.
okay slight er, slight oversight and our little, little bits that were bracing the wall, a
bit of metals now touching them. Got to curt a bit out of that.
Look at this... look at it! Right it's not fully welded up. I've gotta go around all
the seams and stuff like that, but it's all tacked together. Next job, we've basically
got to connect this up to the shed floor, but before we do that we've got to disk cut.
this current, like, hatch or whatever you call it, all the way out, take it out, build
it up, level with the floor, and then we can backfill it with concrete around the whole
thing.
yes! Of course the electric cables there innit?!
Tom: did you film that? Colin: Yeah! Tom: we've cut through the electric cables!
Colin: look at that. Straight down the middle of the cable. whoops! Thank you Tom! Tom:
thank you, don't forget to follow me on instagram! We've got a proper rim. We've got all the
bits and bars all set up, and of course we've got the first part of our lid. Next up is
the concrete. Pour it all down the outside here and start to finish the whole thing off
and stop it sounding like a blooming drum!
How cool is this! So we've got a steel liner down and we've covered it in concrete, but
of course we're nowhere near finished yet. We've got to put all furnishings in it, carpets,
the lights have got to go up properly, but i'm not going to do that until it's actually
connected to the house, and of course there is a little way to go before we do that. Now
some people are probably thinking when you poured the concrete down, wouldn't it just
bellow out the edges? Well basically we got some of the spare insulation from under the
floor, wedged that in the outside and kind of packed it all in, stuffed it all in, so
when the concrete came down it kind of bunded up against it and now it's gone off we can
take that off, and then when we do the next bit we can kind of knock into it, put some
anchor points in and it'll all key together, and then it'll be like one solid piece basically.
Now some people have asked about temperature, how hot is it down here? For the most time
while we were digging and building this, it was a lot cooler down here than what it up
in the shed, but while the concrete was going off, because that's a chemical reaction, it
causes a bit of heat. It's like an oven. As you can see from this thermal imaging camera.
The walls were absolutely roasted and it was generally boiling down here. Now that's kind
of subsided, that's all good. Now of course we've got carpets to put down, we've got the
electrics to put in properly. At the moment there's like a little pipe which we kind of
put into the walls in the concrete so we can just stuff cables down at some point that
will get connected into the house electrics properly, and all done and dusted. But we're
not there yet we've got a lot more to do. Now as for ventilation, while we were doing
this, you probably didn't notice it that much on the video, but there was a massive fan
at the top blowing air down here all the time, because obviously if you welding and digging
you do need a fresh supply of air. We also had a bouncy castle blower, and extreme times
we'd give it a complete belt out, because that was like mega noisy. We didn't really
use that that much. Now up the top the carpet, oh it was heart-wrenching! I've had to get
