Great Escape Tunnel “Dave” Part 3, Will it Collapse? 

I’m glad you noticed, no one has commented about it yet

@@Tornado_Dave Mate that thing is so impressive blew me away.

He is a good laugh, not many other famous people would bother coming to look at my tunnel either 😂

Guy Martin is my idol one person in life I'd love to meet hopefully one day great to see guy supports you in what your doing if he's at your house you know your doing something the people will love

Yes I think Guy coming Round has saved the tunnel collapsing, I will continue making more crazy stuff 😂

Practical Tunnel Driving 1" of concrete per 1' in diameter. The steel needs to meet this minimum specification.

In addition the base section is deficient structurally; due to order of position and means of transferring the veetical and horizontal loadings to this member. Look at the member placement for coal mine tunnels.

You’ve got yourself an incredibly creative mind Dave--really enjoy watching this project

@@rickmoncrieff thank you, it’s good and bad at the same time, can only make one offs before I get bored so not good for making a profit 😂

Yes a special air pump episode as RU-vid seem to want me to post more regularly 😀

Yes he’s a good laugh to been around as well 😀

Trying to spend more time digging so will make more progress before the next video hopefully 🤞

I’m hoping now with the reinforcement it won’t collapse, going to do some testing for part 4 😂

Yes they have made it much stronger, it didn’t take much convincing to get him here to have a look 😀

Glad you like it 😀

Glad you like them, part 4 has already got some problems on which will make good content as well 😂

Glad you like it 😀

The great escape is the theme, hence I want a matching pump 😀

I was actually thinking of doing this but wasn’t sure, I like the idea and will get rid of that slight gap on top 😀

Good job adding the sections for reinforcement, but you'd still want to close the voids as mentioned. When we hand or machine mine tunnels, we grout after to prevent settlement and possibke collapse- I'd have a threaded port in the headtree and sill every 2nd or 3rd section. You can go back and grout the void using a thick cement grout mix. That would close the void and secure the tunnel from bowing. Check that the grout has travelled all around the annulus and you should be pretty solid (tap the sections with a hammer to check the void). In terms of air supply, good to see you're preparing the bag line. You can reduce it down from the larger size to a 4" hose (similar to a dryer vent) and hang inside. You'll definitely need it for air supply and to keep the temperature down. Get yourself a gas monitor while digging at the face - when the O2 levels drop & CO2 rises you can pass out fairly quickly! Always have someone in the shaft entrance in case the sh*t hits the fan. Be safe and have fun 😉

@@mattycireland he speaks the truth!!!

If it lasts 35 years it will do me 😀i can’t see me going down the tunnel after I’m 77. I thought about different options but it would be very hard to seal, so would rather it drained through it. Glad your liking it, next one out on Friday 😀

Yes much better sense of achievement to do it this way 😀

Yes I had to design them to be able to slide together while pushing the sides straight, worked better than I could of wished for 😀

I take it you have a bunker then? 😀

@@Tornado_Dave 😂

Yes sometimes it takes a mate to say you need to sort things out, he was either looking after me or wanted to make sure his staircase gets done 😂

She requires a bit of love, will be using it again in the summer 😀

@@Tornado_Dave That grey cab of yours is what we me had me sub to your channel 😀, hope you do some videos on giving it some tlc

@@willcoleman9691 I’m planning for it to make an appearance on this video series a bit later on 😀

Glad you like it, plenty more videos to come 😀

Thankyou, I also used to work at Rolls-Royce, but left in 2002 after doing my apprenticeship 😀

@@Tornado_Dave, awesome! Small world. Glad to meet you my Brother from across the pond!

@@Tornado_Dave, oh, I worked for them from 2007-2012.

I hope so 😀

Thanks, now when I see pictures with out them like the thumbnail it looks wrong, I get things right in the end 😂

Thankyou

Yes I do sell the kits on my website made over 30 of them so far 😀

I like the idea, not sure how I align the buckets with it though? 😀

@@Tornado_Dave An arm riding on the helix, perhaps with some wheels for guidance, similar to a roller coaster car. Could even be a platform that the buckets sit on.

It would need to be a big vac, would be handy for cleaning the dirt out of the tunnel sections though 😀

Just check your ground water height before you go too far down onto water 😀

@@Tornado_Dave yes will do , love the way you made those metal panels , there bloody string now

Strong I meant

Thanks for the support, part 4 is already looking good so far

He didn’t take much pursuing to detour and call in 😂

Thanks for the nice comment, maybe you could visit are you local?

Hopefully another one end of next week as well 😀

Glad you liked it 😀

The boring machine arms stick right up in the corners so I was trying to avoid them, I think 1 corner it will have to be then it can have moisture drains on it 😀

Very true and I’m hoping for the best 😀

Yes that would work well for those bits

Yes It’s strong now 😀

@@Tornado_Dave Phewww! I can sleep at night now, I was having anxiety just imagining the consequences....😲😊😳😁

Yes we built the landrover together in guys garage episode 3, he’s a good laugh yes 😂

Solid works 2020 I’m using, just the basic version. Yes need to keep thinking about the air vent

Yes I think I need some 😂part 5 out tomorrow night

The great escape tunnel was used for escaping the prisoner of war camp for freedom, this was 80 years ago next month and I am planning on doing a special for the purpose

It’s not working so far 😂

We are on the same wavelength 😀

Yes probably need them

Yes I have a theme of the great escape and this plan is more than just digging a tunnel, more will be revealed in the coming months 😀

I have dug timber frame tunnels with experienced Irish miners, we used 4x9inch treated frame timbers every metre and 2inch wood on all sides, we still had a cave in

Yes that putting the strength every metre, mine is strong every 6” so a different technique, I’m going to do some testing in the next video 😀

@@Tornado_Dave the weak point is at the seems between the original plates now if it helps

Glad you like it thankyou. It’s 25ft total, 10ft down to bunker height so 15ft extra down

Yes I built the staircase, I just put steps all the way down so that I could access the bottom if I ever needed to. They go 15ft further down than the bunker 😀

@@Tornado_Davecould you make a video going to the bottom of them

Yes I am letting it soak through, the gutter sections have already stopped the drips, a vapour barrier diverting the water to the bottom will be installed then clad with the timber on the top and sides. We are having some of the worst weather I have ever seen and it’s good in the tunnel currently, so will see how it goes 😀

It goes dry in summer so don’t worry I will be showing you 😀

I know most people would of had him in the title and on the thumbnail but I thought this was a better way of doing it and he is a mate who turned up to see the tunnel so no BS 😀

Look up timber frame heading tunnel

I will have a look after tonight’s dig, how wide was your tunnel?

@@Tornado_Dave the side frame timbers aka legs were 4x9in 1200mm high. The top frame timbers aka headtrees were the same 4x9in but around 1000mm wide. The bottom frame timber aka foot was 9x2in 1000mm. Each box frame aka section was 1 meters apart along the tunnel with boards between. The top aka head boards were 2in thick. The side boards were 2in thick. Everything held in place by the frames with wedges. Make sure to pack behind the tunnel sheets to avoid voids.

@@Tornado_Dave so 1m wide x 1.2m high.

Tbh I'm only telling you because if something did happen and I didn't say anything I would feel guilty, adding those new metal parts was definitely a good idea

Yes I should of done this, I was on a rush to get it done and got carried away 😂

@@Tornado_Dave lol

Yes I know it would of been stronger but I’m trying to recreate the great escape tunnel so wanted to keep the square tunnel design. Going to do some testing this week hopefully for the next episode on Friday 😀

I built my original bunker before colin did his because I wanted one, but I wanted to connect to the house when I was doing it but the builder talked me out of it, anyway Now I’m finally going to do it 😂

Yes but wouldn’t be as strong as I have done, probably would of been ok thought

Have you seen the part in the video where I put the reinforcements? 😀

I’m thinking of putting it in tonne bags and selling it as it is great ballast

Yes that’s the next project 😀

In response to your comment about piping cold air in, and whether that'll lead to condensation... Moisture condenses when warm moist air comes into contact with cold things. If you had air forced from outside, being piped into your tunnel, assuming the tunnel was warm and being "lived in" (hot mammals breathing inside it), I would not expect that to cause condensation. If you look at Colin furze' tunnel, he has a vent stack which emerges just under the roof of his lean-to. He gets condensation on the metal roof directly above that stack. I guess depending on the design, that could drip water back down the stack into his tunnel, but otherwise, and depending on the design, I think it should be OK. I suppose that could lead to condensation inside the shelter over your well entrance, but I don't think it would make your tunnel wet. Also, cold air is not able to hold as much moisture as warm air - that's why it rains at the west coast, when the warm moist air above the Atlantic gets pushed up to higher (colder) altitude when it reaches land. But, given the topology of your setup, I guess you'd need to be careful not to provide a "drainpipe" down which water could flow if the outside exposed part of the pipe got cold and suffered condensation. Perhaps like a u bend and a drain hole / plenum chamber before the duct enters your bunker?

I think I would struggle to build that as I was tunnelling with out it collapsing in, would be ok if I dug from the top though 😀

Yes it would be but I wouldn’t have the sense of achievement that I will by digging it from below 😀

Some of us do 😙

@@Tornado_Dave i mean not only british, in general the west is mostly gen z with office works for corporations, receiving high incomes to spend it in materialism materialistic life, only ij recent years gen z realized the party is about to end, if not already. War is coming and just before WWII, austerity is coming up to global agenda.

It’s just gravel so nothing really grows in it 😀

@@Tornado_Dave ahhh fair enough, that’s a bummer!

It is themed on the great escape tunnel, it will be smaller once it’s lined with the wood! 😂

It’s doing ok at the moment, if that sink hole wasn’t there we would be pretty dry

The aim of the tunnel is to dig it the hard way to get the sense of achievement, I already have a digger I can use to excavate it if I wanted 😀

Fair enough, thanks for the reply!!@@Tornado_Dave

😂

He’s my mate 😀

@@Tornado_Dave Oh fabulous, sorry I commented before I saw the later part. I thought you must have done some trickery or something. How amazing to be mates with Guy, he’s a national treasure.

Thanks for the tip!

What? 😂

That would be a great idea and I was thinking it but need to do it really, how do I pump it?

I don’t know him, but would love to do a joint video for the 80th anniversary of the great escape next month if anyone knows his number 😀

@@Tornado_Dave Email furzemail@yahoo.co.uk we'll sort something.

@@Tornado_Daveoh no, how long until you build a tunnel connecting your houses

Took some thinking up 😂

Yes already feeling it 😂

It’s to connect my well up to a new bunker and then my house

Glad your liking it, I keep getting criticism saying I’m trying to be colin furse when all I’m being is myself 😂

@@Tornado_Dave nah mate, he doesn’t hold the monopoly on digging tunnels!

The theme is the great escape so wanted to keep the tunnel size correct, it will all make sense in the end 😂

It’s a well so does have water in it some of the year

@@Tornado_Dave so was you who added the stairs?

I’ve got a plan, just for you and Guy I will demonstrate it next video 😀

​​@@Tornado_Daveyou need to listen to this man. I have dug timber frame tunnels with experienced Irish miners, that might not strong enough, we used 4x9inch treated frame timbers every metre and 2inch wood on all sides, we still had a cave in

Colin went through it on one of his videos recently, the concrete will counteract the corrosion I think, mine has no concrete so I need to make it the best I can

@@Tornado_Dave You're right, he took a sample out of his older bunker which has been there fore years. Bone dry and no rust, he also uses plastic membrane to stop damp.

I want the theme to be the great escape tunnel not just a corridor, the finished job will make more sense 😀

@@Tornado_Dave I look forward to seeing the finished results, keep up the great work 🏆

Yes boring all the way 😂

I wanted to have it the great escape theme and want it to be different to other peoples tunnels 😀

Similar concept but completely different techniques, mine is more directed towards the film the great escape😀 Colin’s is more functional

It’s similar in that they are both mad and making a tunnel in there garden apart from that it’s not the same

Thank you and don’t worry it’s all under control I think 😂

Because the theme is the great escape and I want to use Electric carts to drive down it. If I made it as tall as the other corridor I would be very foolish not to dig from above. When I have finished this I’m going to be proud that I dug it by hand 😂

I didn’t want to do it the same as Colin’s, I wanted a small tunnel. Going to do some stress testing on part 4 for everyone 😀

Nothing just the end of the staircase

@@Tornado_Davecould you go down I need to know what’s down there

Everyone keeps saving this am I missing something?

So you don’t think I will make it to the house? Don’t forget to come back in a few months then 😂

@@Tornado_Dave oh I believe it, it’s just a rip off idea 🤣 even the clip of the mud out the shoe exactly how Collin furze done it

​@theunknowngamer9152 Well, surely that means colin furze ripped off the great escape? I've watched both guys and they are completely different. Colin did it to walk through, Dave is doing it similar to the great escape. Both tunnels are awesome 👌

@@theunknowngamer9152I don’t know anyone who would spend all this effort and money to rip an idea off, he’s probably not even making money from it as all that metal is expensive and the tunnel is totally different

It’s meant to be like the great escape tunnel and will be good using the tunnel carts I have planned

In the end who makes a tunnel to get from there house to a bunker that would be to shallow to stop a bomb and made it to be practical
