>Option 2 - HDPE Piping/Culvert

Pros
Light
Cheaper than concrete
easy to transport & move around site
can install by self
can modify with vibroblade cutter
watertight
flexible, will give with earth movement slightly
light enough to be lifted/moved by digger (excavator)
available in 14m lengths

Cons
Round cross-section means reduced space
would have to make custom racks/modules for each tube before installation
Condensation?
3.5m max diameter

>Option 3 - Concrete “Lego Blocks”

(FYI, the plural of LEGO is LEGO, not Legos)

Pros
Could cast on site
Easy to install
can make internal walls also
rooms as big as is possible, support pillars
individual blocks light enough to be lifted/moved by digger (excavator)

Cons
need to make a roof
hard to seal - expanding foam or concrete “glue”?
Environmental impact
Needs lots of concrete
Installation would take much, much longer

>>1202988
How about a metal container welded everywhere, surrounded by rebar, anchored to the ground, and given a 2 feet thick concrete shell? The inside would be sprayed with expanding foam then truck bed liner.

My preference (and I've given this topic an unhealthy and unrealistic amount of consideration in the past) is concrete culvert. It's designed to be buried, comes in big sections, and as you say comes with ladder sections, prefabbed large-to-small adaptors, hatches, etc. Ingress of water has to be a consideration unless your in the desert, and with big sections like this it seems to me it's be fairly simple (although not easy) to get the connections waterproofs with some damp proof course, tar, etc. Sure, they're big and heavy, but just excavating and moving the earth is going to mean you're looking at big equipment anyway, just add lifting equipment to your list.

Best of luck pal, you're a few steps closer to living the dream than I am.

>>1202988
what is the point of a bunker if it can't withstand a nuclear strike
you need at least 2 levels of concrete buried deep inside a mountain

these are only good if you hate people and sunlight

>>1202988
Why looking at prefab concrete structures?
A concrete box can easily be made custom.
That way you only need to get the concrete delivered (or you can even mix it yourself from gravel, cement and sand if you have the time and will).

Culverts are designed for speed of installation but you don't really need that.

Also consider buying hilly terrain and digging into the side of the mountain, you can do it yourself with a small excavator and explosives and you get your bunker pretty much free.

>>1203056
Because unless you also happen to attach a nuclear silo to your bunker, it isn't going to get hit with a direct nuclear strike.

Come on faggot get real.

>>1203056
>these are only good if you hate people and sunlight
Where do I sign up?

Here is a dumb idea I thought up without research how it might or might not work.

Reinforce aquifer caves, drain water, clean water, feed water back into sections of the water table you cut the caves off from or keep for yourself for whatever.

I imagine the process to be tedious as fuck, requiring a diving suit and depending on the materials you use it will be even more tedious, but I imagine rebar skeleton+cocnrete/cement

>OP lost her big sketchpad while moving

This is my rough v1.0 layout proposal...

Dig out trench system. Pave trench. With rebar coming up out the edges. Fill with dirt in a mound over foundation. Bend rebar over mound in the middle of trench. Add wire fence over rebar/dirt mound. Weld. Pour concrete. Top off with dirt. Dig out your reenforced tunnel system and blow in insulation. Add more dirt and rocks on top burying whole thing in a man made mountain but with a hole down the middle. Build shipping container castle on top of mountain. Add bat pole to bunker network.
Win.

>>1203091
Not a good idea. When you start drying out stuff or soaking stuff it changes everything in a very fundamental way which can totally wreck the structure. Your grave may very well be marked by a sink hole.

I used to make those pipes and culverts that are designed for water 90% of the time use a rubber seal before you join the next one in and they could be installed by 1 person with a front end loader probably would need a spotter tho to speed it up

You could build your own, it doesn't look that difficult - print your own forms on site, install rebar and place on pad, fill 3d-printed forms with concrete.

Think a giant Prusa i3 made out of I beams, that would be awesome

CNC can pretty much be scaled as big as you want. I can imagine half a bridgeport mill welded to a 30' x-y slider with 1/2 hp steppers, though I'm not sure how a 3D printer's nozzle can be scaled.

If you're extruding concrete, how about a metal auger/Archimedes screw assembly, with a concrete pump on the supply tank to keep feed pressure up. Could run the whole thing from a RAMPS board maybe? or an old PC?

Would be awesome to be able to make custom 3-D printed rooms, just build it modularly. Can design in staircases, access ports, all sorts. Just have to knock it up in CAD first....

>>1203130
>rebar
No they're not. They're meme-tier.

>>1202988
Guy i know dug trenches. Filled with concrete. Poured a pad for a roof. Dug it out with a skid loader and put the dirt on top. Power wash walls and pump or drain water out. Lay rock screenings down amd whacker packer and pour pad for a floor. Paint walls and ceiling with mold and moisturereaistant paint or rhino liner or flex seal or whatever u want.

Pack your shit and move in.

Wait, OP is female? a woman, with a bagina? who wants to live in a bunker and be a crazy inventor? We should get married, or at least be friends, where do you live? I'm in Liverpool UK.

P.S. http://www.colinfurze.com/bunker.html this will help you.

>>1202988
I recommend your own excavator. A 20-30ton excavator can be had for well under 10k any decent money.
A big excavator can probably lift those concrete sections. Mine lofts 2,4 tonnes when the boom is fully extended, 7-8 tonnes if lifting beside the machine. And if I recall correctly it's with the bucket. This weight is 60% of the tipping weight but I recommend not to exaggerate, toppling over is dangerous.

An excavator is an extremely versatile tool.

But if I'd really would build a bunker I'd probably dig a hole and pour the concrete myself. It's a bit over 100€, depending on what kind of concrete per m^3 pumped. Relatively cheap, that is.

>>1203353
I wonder how easy it would be to make CNC reinforced concrete? You'd need some railway-esque rebar placer.

everyone don't forget when it comes to the underground)
1) ventilation, gotta vent in/out good/bad air exhaust, heating/cooling, poison gas/ clean air (always multiples/different types for safety/regulations)
2) water management, for occasional flooding/rain in short period, neighbors flooding their fields/fires/etc aka sump pumps, again multiple places and types
3) power and energy, generators underground equals multiple input/output for exhaust/air/fuel/power/etc, same with solar/wind/geothermal if you tap those underground burning coalmine fires/underground rivers

In the end, your hidden away place WILL be noticed by the locals if only because your location will inevitable have NOTHING TO OFFER above ground to explain your comings and goings

You could probably just get a truck load of tar much cheaper, and spread on the outside as a moisture barrier

Concrete pipes can be really huge. Like 50 or 100 feet, if you need them. The cost of shipping is going to be $$$ though.

OP Here,
My plan is as follows:
>Get Field
>Get planning permission for house and "security bunker" (UK Planning laws permit this, and you don't need permission for an under 30M^2 floorspace bunker, interestingly)
>Phase 1: Build house with basic groundworks and hookups for bunker
>Phase 2: Turn big, tall barn into workshop and build the 3D concrete printer
>Phase 3: Buy biiig excavator and dig a fuck-off huge hole
>Phase 4: Get pad laid by pouring in a huge amount of self leveling concrete, then a rebar layer
>Phase 5: Print bunker in modules according to print volume of your huge printer
(I'm thinking an inner shell is printed, rebar is fitted, then a separately printed outer shell is fitted. Once in position, the shell is filled with concrete, sealing it and strengthening it. Large counterweight motors could be attached to shake out any bubbles and ensure good internal adhesion.)
>Phase 6: Install modules & backfill with more concrete, gravel, soil, maybe hesco bastion or something designed to work like that underground?
>Phase 7: Install interior environment
(I'm thinking expanding foam like the Murricans use to insulate their flimsy wooden shacks they call homes, then something on top, possibly spray-on stuff - Using lots of ventilation, of course)
>Phase 8:Install bunker barebones like; doors, stair rails, ladders, lifts, electrics, water, ventilation, networking, gas supply, waste disposal, septic tank, generator etc...
>Phase 9: Use the power of the weaponised autism of /diy/ to come help me fit it out (Paid, with toys to play with and beer and stuff)
>Phase 10: Clear out spaghetti and move in. Bring a mop.

This is of course, assuming that I make at least £300,000 in personal profit after taxes this year, that amount is at least enough to get started with the land, house and maybe printer...

Look for disused nuclear bunkers - preferably ROC or council ones. the emergency planning officer at the council would know where they were and who to contact if the council are interested in selling.

Good luck with the first step. Land with planning permission is hideously expensive, unless you're willing to relocate to rural Wales or the Scottish highlands. Buying land without planning permission is a gamble as you'd have to spend, iirc, 5 years continuously inhabiting a mobile home on the land, while using the land for agricultural purposes, to demonstrate the requirement for a permanent syructure to be built. This is the point where my autistic inner 12 year old says "fuck it" and i resign myself to saving up for an existing farmhouse with land.

You're correct that we're allowed to construct a 30m2 fallout shelter (one if the few personal liberties we still have in Britainistan, get in there quick before Labour get back into power and declare back garden bunkers forbidden due to terrorism laws or something), but remember they have to be at least as far horizontally from the main building as they are vertically deep. So, that puts paid to the idea of having a bunker directly accessible from a cellar, unless you plan on digging an illegal tunnel from your house to the bunker. I'm game for that, but it would have to be hush-hush.

>>1204676
Cold war era bunkers sell for £15k or so each, usually on a tiny parcel of land, and are effin' tiny. They cool and I'd buy one if I was a keen hunter or bird watcher, but for my secret base fantasies they just don't cut the mustard.

you could probably actually build one for pretty fucking cheap if you don't mind getting your hands dirty. Just get a couple used 50 gallon drums, and fiberglass them together to make some compartmentalized pontoons. doing some quick math, a gallon of water weighs about 8.3 pounds multiplied by 50, gives you 415 lbs of buoyancy per drum. so something as small as 2 pontoons made of 5 drums a piece could support a 1 ton structure easily, and still give you plenty of margin for furniture, people, and supplies.

of course that probably wont be strong enough to survive a hurricane or tsunami like those crazy survival boats, but it's something.

might be horrifying, but first thought improvements:

Mount that table, to the left of the mini range, onto a track. Set it at a ever-so-slightly higher level then the range&sink, with a hidden slot underneath for range controls if needed.

Mount the faucet and knobs on the wall instead of through the counter. Add some interlocks to the range power and water. Then slide the table over to collapse that area for more space as needed. You could also make the table-on-rail longer, doubling counter space or deleting it as needed.

Coverage for getting a professional crew to dig this would be that you want to bury a methane digester or water storage. It would require a large, deep hole (with trench plates) then you would set up a base and pour a foundation that is keyed to receive the pipe segments. Perhaps the big central chamber and a side tunnel (or two) of smaller pipe that you can mount a ladder or lift in and use as needed. The segments would be stacked and sealed together, likely covered with some kind of tar or sealant, layer after layer and backfilling dirt on the way up.

>>1207461
>stealing away with one of the few sunken nuclear submarines
I guaran-god-damn-fucking-tee that if this shit was abandoned, it were abandoned for good reason. when the navy decides to scuttle a vessel, they typically gut it first Even if you can "recover"/steal a nuclear sub you would probably need to use some weird ass powering, and also some weird ass state regarding NOAH

>>1207505
There are a few that weren't scuttled, but sank with their crew as a result of some accident. Of course, the majority are below 3000 metres and thoroughly crushed, so it's probably easier to just build a new one. But a recovered sunken submarine or two would make great scavenging materials for construction.

I'd go another route, half n half:

Excavate, but not more than 2m (2m generally accepted as requiring engineering, so aim for less). Then build rammed earth walls for the first floor with excavated material and whatever you need for the balance. Careful with drainage around this step.

I'd add a second storey though, so we're well out of bunker territory there. But fuck that, I don't want to sleep in a dank hole.

Plus, you can just use this and stay the fuck away from any dots on this map. If you want to be doubly safe, use nuke radius calculator to figure out the safe distance from all of these targets in the event of a tsar Bomba size nuclear strike,and build anywhere that doesn't fall in the danger zone.

ITT: unclear project parameters

If you talk about proper bunkers, it is a wheel already invented, the only problem is it is a multimillion dollar project which falls outside of /diy/ territory.

If you talk about a truly diy scale bunker, then there is the question of why a random location (the typical backyard is a poor location), and why not make arrangements to move, and why make a bunker when a military one is safer for actual happenings, also the question of lifestyle and hooking up to city grid or other systems, also the security issues, literally millions of why before you even get to doing proper engineering in a clearly defined site with proper requirements.

This topic remains a wanking exercise until proven otherwise with actual project parameters, e.g. bunkerbro bunkers

unless you have a specialized heavy duty digging machine, you are probably going to need to dig the walls of your hole at about 45 degrees anyway, so you would be digging more for less space, not really worth it unless you want to dump a bunch of concrete on top to make it more bomb resistant

I was thinking of reinforcing some relatively narrow-diameter (2-3m) piping with many cross-braces and rebars so it can naturally hold the pressure without turning the surrounding earth into a structural element, similar to how a submarine does. This way "you" can always go deeper as you reduce the inside diameter with respect to the outside diameter.

If I could dig on the go and cast pipe segments as I remove the earth underneath me (via fracking?), I could theoretically get deep enough to get myself some thermoelectric power generation, bonus points if there's a cool aquifer between the heat and me. But that's just an economically optimistic pipe-dream (heh), I really just want an inverted tower.

I like the tower idea because it takes advantage of an optical illusion often used by department stores. High ceilings in cramped spaces give the illusion of spaciousness.

No, it wouldn't. You are an idiot who knows nothing about shipbuilding. Fucking retard. You'd spend more salvaging and scrapping it then you'd spend on new metal. How dare you not know that? Fucking babbling 12-year olds go die.

Not viable unless you get tall rebar in there going as high as the concrete is to be deep, and a selection of circular rebars welded to it, but after that it's a pretty good idea, pic related. You could throw the reinforcing structure together on site, and make it higher if necessary while it's still sticking out of concrete. Problem is you can't make the bottom walls thicker than the top without making big modifications to the cast, so you'd either have collapsing walls at the bottom or super thick walls at the top if you go deep.

Maybe you could weld a rebar ladder to the top of the reinforcing structure that spans the whole reinforcing structure's height so you can get down to the bottom regardless of the downward progression? It would have to overhang the wooden cast, so maybe it would have to be reinforced from multiple sides.

Only Russia has enough nukes that in a war they'd be able to do true counterforce, and even in that scenario you just have to say more than a couple miles away from strategic targets like air bases and missile silos and city centers. National guard armories aren't even on the target list.

All other nuke capable countries don't have enough to even target all our missile silos. So they'll hit major city centers. Avoid those places and you just need a fallout shelter. Which coincidentally is more useful in other scenarios like pandemics.

>>1203130

That's controversial even among prepped. Experts disagree on how much of a threat it really is and how effective countermeasures really are.

I'd wrap your shelter in copper mesh if I were you, but then dig under your shelter and put a much better Faraday cage with your electronics and data down there. Or at least backups.

The government has been hardening the grid against this or a Carrington event for the past year now, so the window of vulnerability where this alone fucks civilization is closing.

>>1226744
>copper
I thought you wanted high magnetic permeability, but I might be wrong. Looking at how they work, it probably is better to just use a good conductor.

>>1226496

Also try the homegrowman thread on /out/.

And be advised: the DEA tracks electricity usage for grow light use patterns and in some districts even posts officers at hydroponic supply stores. If you're trying to grow pot, you will probably be discovered. Even if you aren't, you should give the local cops a call and explain you're a hobbyist and ask what you can do to help them make sure you're not Walter White without having your dogs shot in a midnight no-knock SWAT raid.

>>1226797
>>1226797

When you're far enough underground, this is gilding the lily, but it's also a sensible precaution. Just keep your SHTF electronics, including any backups you want to keep, unplugged, charged, and fully enclosed in your Faraday cage. Leaving your ham radio and antenna set up all the time is great, but it will be fried if anything is. Obviously the antenna has to be in the cage and non-functional to be shielded.

I've talked to experts. Laughing it off seems to be in vogue right now, but half laugh it off because any Faraday cage a prepper is likely to have won't be enough due to EM saturation. The other half say that most electronics and infrastructure will survive a Carrington event or EMP attack and so prepping is useless for that reason. These are pros who study this issue in a national security context, with very strong technical backgrounds. They all sound so sure that anyone who knows the science agrees with them.

So imo it's worth preparing for because a lot of the middle ground between those two groups is a disaster that is really bad and that we can prep for.

>>1226866
Is putting your electronics in a microwave good enough? What about a bog standard steel safe? Also, you could probably make a few disposable ADC modules attached to your antenna so you can feed them through optocouplers and back into DACs, so you only fry the disposable electronics.

>Still true if tube-based?

>>1226868

I'm not an expert myself. Like I said, I've talked to them, and they're all over the map on how much if anything is enough. It seems like the only consensus is that EMP is no big deal, but they all believe so for contradictory reasons and nobody even acknowledges that there are differences of opinion on the subject.

I will say that the enclosure you use depends on the frequencies you expect, but I don't know enough to shit up a thread with speculation.

>>1227855
I'm enough of a physics student to consider simulating the EMP from a nuclear blast, I might get on that eventually.
