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
I'm very glad to see the reinforcements! Soil is heavy and those roof members were looking a little skint. I like my "Daves" very much alive to commit further construction atrocities like this! Take care!!
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.
Many years ago, I read about a clever system to ensure an air supply in the case of a tunnel collapse. You run a sturdy hose from the entrance of the tunnel up to where you're working. In the event of a collapse, you can still breathe through the hose until help arrives or you manage to dig your way out. Even in the event of a multiple collapse that cuts off the end of the hose, and you’re trapped in both directions, you can simply cut the hose at any point in the tunnel and still get air. I suppose you could rig up something more substantial using large diameter plastic plumbing pipe. Maybe drill holes along its length every foot or so, and seal them with duct tape or something. If you get trapped, rip the tape off the nearest hole so you can still get air. Might be a prident safety measure as the tunnel gets longer. Also, weld a roof with a "roll cage" onto that little cart so you're not instantly buried if there is a cave-in.
Dave, if you want to secure the soil after the tunnel sections are put in. Drill a hole in each section after assembly. Then spray in a can of cheap expanding foam, like "great stuff". This will fill in the voids and insulate the tunnel sections. And, the stuff is dirt cheap.
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 😉
The only thing I can think of that will help later down the line with the water problem is to put a square rubber gasket on before you screw the sections together, it's one more step but as long as you have it in one square piece you may be able to get away with no future leaks when it rains, or water the yard. It doesn't matter how tight the sections are together, water will find it's way through if there's nothing to seal the water from getting in, and once the water gets through nothing can stop it from rusting in the future galvanized or not. Which means you or someone after you will have either a collapsed tunnel or a decaying tunnel that they'll either have to repair, dig up, or replace entirely. Now that I think about it if the outer layers were painted or coated with something besides just galvanized base metal you could make it potentially last even longer, but all the one's you put in will decay over time unless you pull them out individually and coat them. On average the steel will last 35-70 years, but if you coated them they could last even longer than that. I'm just thinking of how to make it last the longest, I've no idea what your future plans are but this is just my observation. I dropped a follow, looking forward to the next episode. Cheers mate.
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 😀
for some reason I was really impressed with how you managed to get those strengtheners in all the way round given the sides were probably bent inwards. have my like.
You remind me of the great escape or Colin furze as long as you have air flowing though the tunnel when completed you shouldn't need extra ventilation you just need temporary air for now
I’m so delighted to see someone able to assess risk and choose for themselves their risk responses. What I mean is, so often others believe that THEY should be in charge of others individual risk and dictate what the responses would be. However, a person who is allowed to be in charge of their own risk is much better able to process suggestions and information of others…than someone being forced. Stay free my UK brothers and sisters.
Subbed when you fixed up the hat channels Dave. Not that you needed them but rather that it was easy enough to do and it adds the strongest possible outcome. Super job, Keep it up!
Great project! If you added a helical guide rail around the central post of the spiral stairs, it could guide the buckets up and out without bouncing off stairs and the post.
@@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.
I think the flat metal sections need bracing with some box section or tube, much like the design of a crane jib, for added strength and rigidity. I just feel if it collapsed, those flat sections wouldn't be rigid enough to hold back the weight of the soil above. Edit- just watched the bit where you brace it, great minds eh, 😊👍
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 😀
Fun tedious project, but love it. Don't know if it would work Dave, but a big workshop vac might make life a bit easier, getting smaller stuff out of the tunnel.
Looking great. Cant believe Guy Martin is your mate and of all people, he thought it was crazy and dangerous 😂 Hope you turn this into an attraction and i can come visit. Much love The Burgoynes ❤
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 😀
Should really make the tunnel higher lol it would be so much quicker digging being able to stand up secondly I would use a vaccum to pickup the dirt and feed it up out of the well in one shot using a icb an a wet/dry vaccum to pickup the debris and bring them up the shoot just either make a box with a dumpable bottom bonus is you will spend less time moving dirt physically and it will draw the dust out aswell
I have dug timber frame tunnels with experienced Irish miners, that is likely not strong enough, we used 4x9inch treated frame timbers every metre and 2inch wood on all sides
@@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.
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
To prevent the metal from bending in when you hit it with a hammer/mallet, put a piece of sacrificial wood on top of the metal then hit the wood so that the wood takes the imprints and not the metal.
Since there is hardly anything supporting the sides and roof of the tunnel, does he have a contact or 2 who knows that if he does not contact them in a certain time frame that they should go and try to rescue him should a cave in occur ? Because can see the support for the tunnel is extremely flimsy, and the soil with water is wet - corrosive - heavy - and could easily cause a cave in.
Should have used 4"x8"x16" concrete block then placed a half steel or poly culvert on top then packed concrete about 4" thick on top of the culvert leaving a little at the end to put the next culvert half on top the edge to continue.
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 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
I'm very intersted in your project and I hope that it will work out. but I am really not confident that these sheet metal planes will work. colin furzes attemt might be overengineered, but that's better than being buried in a hole somewhere.
I reckon you should probably put in some fans to force some air circulation in that tunnel. If it were me, i think id want somethign that fetches fresh air from the surface, pipes it down your spiral staircase, and then a flexible hose dragged down your tunnel as far as you can get it. Obviously, i appreciate you never asked for my advice, but thats the internet hivemind for you! Edit, just saw to the end of the video where you talk about exactly this! Sorry.
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?
Grow up, oh second thoughts don't what an amazing escapade. Have you considered pumping grout around the sections to create some bedding and adding a bit of strength?
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 😀
I feel like you are going to have alot water ingress in that tunnel. I thought a rubber gasket might work but you'd still have the 4 corners to worry about. Any thoughts on how your going to stop this ?
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 😀
I get the safety point but what did they actually use in the real tunnel and for any war tunnels. Any way not to take away from another great video, Sorry if i missed it but do you have an expected eta to the house??
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
@@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.
We’re you inspired by Colin Furze? Either way, great channel, keep it up😊 ps. Have got a Radon Monitor …….. just incase. Ps why didn’t you make curved reinforcements rather than square Surely that would have been structurally better from a physics point of view ?… edit… Just read other comments and I see you find this on the great escape so I understand now😊
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 😂
It still worries me a bit Dave sorry mate it really is a life or death decision. If you die it means no more videos lol. The miners used great big timbers and end ways they have a massive crushing force. I have been doing ground works for years and I have seen the crushing force behind unstable ground. It’s untested really. I guess when the cavities above your frames self compact it will be safer. Could you strength test one section just to see how it performs. I know they all work together but testing one might instil a bit of confidence.
@@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
@@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.
Why not make it big enough to stand up in? Yeah it would be a lot more material to remove but heck at least you could stand up when you’re doing it and when it’s done you could just walk down a hallway…
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 😂
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.
@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 👌
It’s modelled on the great escape tunnel, I didn’t want it full height as if I was doing that I would of been crazy not getting the digger out 😂 it’s not lazy making a small tunnel, harder work really. I’m in a low radon zone here.
Nothing more British than using a miniature Land Rover to winch out buckets of dirt from your backyard tunnel, excellent 👍
I’m glad you noticed, no one has commented about it yet
@@Tornado_Dave Mate that thing is so impressive blew me away.
Omg guy is the only famous person I wish I could meet. He is my hero. You are a lucky devil Dave.
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 😂
You're a madman, I can't wait for part 4! Two weeks?!!

I’m hoping now with the reinforcement it won’t collapse, going to do some testing for part 4 😂
Brilliant, can’t wait to see it finished.
Trying to spend more time digging so will make more progress before the next video hopefully 🤞
Just come across this. Brilliant! I will
Go back and watch some other videos. Proper British mad engineering, the way it should be
Glad you like it 😀

Awesome structuring the new fabrication bits will really do the trick , great work Dave and great to see Guy there to 😊
Yes they have made it much stronger, it didn’t take much convincing to get him here to have a look 😀
for some reason I was really impressed with how you managed to get those strengtheners in all the way round given the sides were probably bent inwards. have my like.
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 😀
You remind me of the great escape or Colin furze as long as you have air flowing though the tunnel when completed you shouldn't need extra ventilation you just need temporary air for now
The great escape is the theme, hence I want a matching pump 😀

The new bracing system looks very robust - nice job!
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 😂
Great to watch the progress and you answered the question of why not just use a digger from above 💪🏻👊🏻
Yes much better sense of achievement to do it this way 😀
I’m thinking of building a mini bunker now ,well done dave.
Just check your ground water height before you go too far down onto water 😀

Where do the stairs go below the water line? Did you build them? This is a cool project
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 😀
Just a thought Dave... Maybe a shop vac with a long hose would help in cleaning out the corners before you install the metal.
Yes that would work well for those bits
Nice to see guy there and with the same top as me
He didn’t take much pursuing to detour and call in 😂
I guess if people didn't take risks, we would have a pretty boring Internet. I hope this ends well.

You should curve the roof Dave. It would be alot stronger.

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
I think the air vent would cause condensation, also what CAD software do you use ?
Solid works 2020 I’m using, just the basic version. Yes need to keep thinking about the air vent
I'm very intersted in your project and I hope that it will work out. but I am really not confident that these sheet metal planes will work.

Guy Martin! Now how’s that for a cameo 👍🏼👍🏼👍🏼👍🏼
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 😀
My question where’s all the dirt going you selling it or dumping it somewhere
I’m thinking of putting it in tonne bags and selling it as it is great ballast
I feel like you are going to have alot water ingress in that tunnel. I thought a rubber gasket might work but you'd still have the 4 corners to worry about. Any thoughts on how your going to stop this ?
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 😀
Looks like a good way to move air.
It’s not working so far 😂
I get the safety point but what did they actually use in the real tunnel and for any war tunnels. Any way not to take away from another great video, Sorry if i missed it but do you have an expected eta to the house??
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
I would dig a trench from above with an excavator and then fill it up, it would be much faster and cheaper.
Yes it would be but I wouldn’t have the sense of achievement that I will by digging it from below 😀
Could you make your tunnel sections half the depth ?
Yes but wouldn’t be as strong as I have done, probably would of been ok thought
How deep is the bottom of the well total, great job Dave
Glad you like it thankyou. It’s 25ft total, 10ft down to bunker height so 15ft extra down
Awesome video, subed
Glad you liked it 😀
Why not make it bigger ?
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 🏆
This is awesome! 👏 👏 👏
Glad you like it, plenty more videos to come 😀
That's strange, a brit actually working. Haha
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.
I’m here for the tunnel, for sure, but I’m 100% on team plant a garden with that millennia+ old soil. Please and thank you.
It’s just gravel so nothing really grows in it 😀
@@Tornado_Dave ahhh fair enough, that’s a bummer!
heck yeah, another tunnle dave video
Hopefully another one end of next week as well 😀
We’re you inspired by Colin Furze? Either way, great channel, keep it up😊 ps. Have got a Radon Monitor …….. just incase. Ps why didn’t you make curved reinforcements rather than square Surely that would have been structurally better from a physics point of view ?… edit… Just read other comments and I see you find this on the great escape so I understand now😊
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 😂
so do you and Colin furze have tea and talk about your bunkers and tunnels?
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.
В рост не вариант копать?
Good to see safety squints in use here
Yes probably need them
Is there any reason not to just rent an excavator for a weekend, insert the panelized or concrete form tunnel into the ditch and burying it?
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
This is awesome
Thankyou
It still worries me a bit Dave sorry mate it really is a life or death decision. If you die it means no more videos lol. The miners used great big timbers and end ways they have a massive crushing force. I have been doing ground works for years and I have seen the crushing force behind unstable ground. It’s untested really. I guess when the cavities above your frames self compact it will be safer. Could you strength test one section just to see how it performs. I know they all work together but testing one might instil a bit of confidence.
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
Plastic tube use the flat profile used for kitchen extractor units .try Ur plumbers merchants
Thanks for the tip!
What about water infiltration? Ive built underground vaults with rebar and sump pumps and water diversion. I see the sink hole water will get in
It’s doing ok at the moment, if that sink hole wasn’t there we would be pretty dry
Cool !
Thats ductwork u running some heat to ur bunker or what?
😂
This series is feels like the bastard love child of @colinfurze and @Askjeffwilliams and I love it.
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!
WTF …? How did you get the Guy Martin clip? Did you use some sort of AI?
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.
This seems similar to that Colin feller?
Similar concept but completely different techniques, mine is more directed towards the film the great escape😀 Colin’s is more functional
Why not make it big enough to stand up in? Yeah it would be a lot more material to remove but heck at least you could stand up when you’re doing it and when it’s done you could just walk down a hallway…
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 😂
at least he is using galvanized unlike the other big tunnel guy who is using steel which will rust over time even if its painted it will rust
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.
Use a plastic dead blow hammer. A lot quieter.
your shoulders will be soo conditioned by the end of this dig.
Yes already feeling it 😂
What’s at the bottom?
Nothing just the end of the staircase
was supposed for that pit to be filled with water?
It’s a well so does have water in it some of the year
@@Tornado_Dave so was you who added the stairs?
El Chapo of the UK 🤣
BTEC version of Collin furze bunker/ tunnel and connect to the house. No? 😂😂
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 👌
Sankyu 🚧👍
what is the purpose of your bunker
It’s to connect my well up to a new bunker and then my house
why didnt you make it full size so you can walk down it
I wanted to have it the great escape theme and want it to be different to other peoples tunnels 😀
I would have went with standing height even if I had to dig deeper to make it work.
The theme is the great escape so wanted to keep the tunnel size correct, it will all make sense in the end 😂
dude, i subscribed, and have great faith in you. dont fuck it up plz !)
Thank you and don’t worry it’s all under control I think 😂
Too small. Should have made it bigger. Colin Furze had no problem making his larger.....which means you're just lazy. Any problems with Radon Gas?
It’s modelled on the great escape tunnel, I didn’t want it full height as if I was doing that I would of been crazy not getting the digger out 😂 it’s not lazy making a small tunnel, harder work really. I’m in a low radon zone here.
Was that... It was?! Whaaaaat
What? 😂
I still don't understand the point of a tiny tunnel that's only big enough to crawl through. No one will want to use it later
It’s meant to be like the great escape tunnel and will be good using the tunnel carts I have planned
It's boring and it will be boring until the tunnel is complete 😛
Yes boring all the way 😂
Chilean miner arc incoming
have you given up ???
Not at all, just finishing off part 5, it will be on here Friday evening , have you watched part 4?
