How many negroes do you own?

Minecraft General?

I can help. What type of soil is around your property? Also, do you know the water and frost line?

feasible, as long as you brace the tunnel system

(chemist, so take that with a grain of salt)

>>2355049
I think my soil is mostly clay-like. Not sure about the rest.

Anyway, I'm just looking for general ideas about how feasible this might be. The fact that I've never heard of a person doing this on their property leads me to believe there are some inherent problems.

Engineers reporting for duty
How can we help?

I've thought about this for fun, but one thing I would be worried about is the tunnel collapsing.

Are you near a large body of water, like a river, lake or ocean?

Also, how deep and long are we talking?

>>2355074
why would people advertise the fact that they had underground tunnel systems on their property?

>>2355091
I'm about a mile from some streams, and about four miles from a lake.

I'm drawing you up a very basic plan, if you want a more detailed plan and specifics, go ahead and give me your email address.

watch for power lines/water pipes/sewers etc

>>2355190
Thanks for this.

Like I said, I'll draw you a full on 3-d model if you give me your email and we talk about this further.

might want to throw in a ventilation tunnel too..

>>2355206
Excuse me, but are you the Engineer here? No. Go play with your music and accounting somewhere else.

>>2354980
Well it depends on your soil conditions. Also you'll need a building permit. If the feds find out, you'll be in big trouble if you don't have a permit.

>>2355214
How does one truly govern the people to the point where the said people have to obey the governing body? Fuck that shit

I'm assuming you're not worried about permits or pipelines?

>>2355212
hmm.. how about I bury you underground and we see how long you last?

>>2355214
Honestly, the feds don't give a shit, it's state and local that need worrying about.

As long as you are not digging under people's houses and such, such a permit will be issued.

>>2355190

That. Isn't. Right.

Do you want to get someone killed? Or are you just that incompetent of an engineer?

What principle are you in? Are you even civil?

>>2355255

Architecture. What do you see wrong with this?

>>2355227
building permits are designed to protect people from themselves and actions by stupid people. For example, in my city, some fucktard decided to build a huge elevated deck not according to building codes. He had a party on that deck, said deck collapsed, and people died.

That being said: http://www.ehow.com/how_7733836_dig-tunnels-underground-rooms.html

>>2355257
>>Architecture
that'd better be architectural engineering... Otherwise, you have no idea what you are doing.

>>2355275
Sorry, I thought the Engineer was implied.
Anyway, for real. It's better that someone point out a problem right now than allow me to mislead this guy.

>>2355257

Zero calculations. No real data given. Those supports would be very unstable a few meters under in the right soil.

If I ever tried to pass that off as work, I'd lose my liscence.

To the OP, do it right or you'll kill yourself. Get a permit, consult a firm. This is really dangerous stuff.

you dont have to do shit. you dont even have to be a citizen. but some countries dont like sovereign individuals

secede or gtfo

>>2355290
this anon is working for the man

>>2355290
Of course. I completely just bs'ed it up right here right now. By no means am I encouraging op to go build a tunnel based on the mspaint drawing I gave him.

i saw on the show american pickers some guy dug a tunnel system to store his junk although he was it the woods where the ground is probably very stable because of the trees

>>2355241
im pretty sure there's a database on whack jobs building underground bunkers. you dont want to be on that list


seriously auto add capcha to post already, i think im making this up

CS major here

OP, the tunnel ceiling has to be strong enough to support all the soil above it... the tunnel walls have to be strong enough to prevent soil bursting in from the sides. That will give you an idea for the strength requirements of the materials you're gonna use

P.S. I have never taken any classes on anything like this

>>2355290
This guy did it, and he didn't buy permission...I mean "apply for permits" first.

Massive problems OP. It's likely to collapse and cause a massive amount of damage. If you think regular maintenance would solve this, that actually makes a large scale collapse more likely.

>>2355352
Yeah and I bet many of his friends died trying to dig tunnels

>>2354980
Unfortunately if you dig a tunnel like that, the entire thing will collapse. Also apparently my simulation says your house will catch on fire.

More realistic answer,

There is this one guy in canada that bought a bunch of old school buses. He dug trenches big enough to bury the buses, and uses them as an underground house. For you, it would probably be easier to do something similar, although I would recommend big pipes instead of buses.

>>2355389
forgot my simulation

>>2355375
See that little tube he is next to....

Get it yet?

All you brainiacs, I got a humanities degree....let me make it easy for you....OP

USE STORM DRAINS BIG ENOUGH TO GET THROUGH

>>2355389
>>2355389
Why would it collapse, genius.

he can dig a ditch and bury the tubes

Wow, so many dumbasses here.

A simple way to ensure maximum tunnel strength is to have perfectly cylindrical tunnels (you want actual tubes). Don't believe me? Look at every single large airplane or gas canister in the world. If you don't want to walk on a curved floor, build a simple flat walkway running along the bottom of the tube.

Make it out of concrete reinforced with rebar. Have a space between the soil around your tube and the tube itself. Fill this space with something mushy (think foam spray insulation). When it's time for an earthquake, your tube will be cushioned and will move far less than the surrounding earth.

A good thing to have is waterproof concrete. Obviously if you build above the water table there won't be many water problems, but hey, you never know what could happen.

The deeper your tunnels go, or farther from the entrance, the more a problem air quality is. The easiest way is a ducting system that pumps air straight from the outside (by the entrance) all the way to each dead ending tunnel. This fresh air then gets pushed back through the tunnels toward the outside. The air pressure has to be high enough so that standing in the tunnel you feel a very slight breeze (Like 1 mph). I believe the best place for these ducts is under the flat walkway. This is also a good place for any wiring/plumbing.


I am in no way an engineer, I have done almost zero study on mining/tunnel building, and I recommend you do not follow my advice. However, if I ever were to build tunnels under my property, this is how I would do it.

>>2355393
>>I got a humanities degree
he got a humanities degree

OP you've obviously never dug a hole in your life if you think you can dig something like that by yourself.

>>2355445
yeah, and I got the right answer too...UNLIKE YOU

>>2355437
Picture had no support

>>2355485

>>2355485

the picture had no sun and moon either, did it exist in a white vacuum?

Idiot.

>>2355486
lol

you still dont tell the moron how to do it....why would he have to dig straight down?

Fool.

the end product can look like that, you know, you can MOVE DIRT, and REPLACE IT AFTER YOU FINISH

>>2355460
He can do it. However it will take the better half of his life span.

You're better off asking /k/.

>>2355497

>>2355496
I already gave the perfect suggestion. dig trenches. place tubes. cover in dirt.

>>2355441

Pretty much this. Bury some reinforced concrete tubes and call it a day.

It's your safest bet. (And probably the most expensive.)

>>2355441
Bury old airplanes, they already have airflow systems and lighting.

For the record, just because the VC did it, doesn't mean you should too. Those things were a structural nightmare and were a collapse waiting to happen.

>>2355534
that would be AFTER the humanities major informed the thread of the idea!!!!

>>2355579 After humanities
Notice the sequential nature of 4chan posts. and the time stamps

>>2355389 me 21:12
>>2355393 humanities 21:13

OP you'd be better off buying an abandoned missile silo.

>>2355538
>>2355441

Not OP but do you guys mean pic related?

>>2355618
Those would work

if Mexicans can, then you probably can't

>why would people advertise the fact that they had underground tunnel systems on their property?

They wouldn't. Only serial killers have them.

Mexicans can!

>>2355618
That seems like the only feasible solution to this-make sure you seal them well OP, and talk to an engineer who knows about things like this professionally before you start out.

The VC had decades of experience building tunnels using bamboo and shit, and many of them were stone-cold motherfuckers who just didn't give a shit if they died.

>>2355074

Time, scale, underground power / gas / water etc..., bracing of a soft-earth tunnel, practicality... List goes on.

>>2355657
>only serial killers
I feel a little insulted.

>>2355589
>>2355589
Mine was first, fucktard.

The picture was everything, fucktard OP was too slow to get it.

>>2355352

And, apparently, you too.

Nice to see "PASCAL" is impressing us with being milliseconds faster than a humanities major.

(but not really since I posted the solution in picture form first)

>>2355618
retard, see
>>2355352
Do those look like reinforced concrete tunnels?

>>2355767
ON closer inspection I do see a pipe in that picture.

>>2355799
no. do not be reasonable. asshole.

I am being right AND belligerent that is supposed to elicit an emotional response!!!

>>2355393

>>2355806
I'm sorry, I'm not good with emotional responses. Can I draw you a picture instead?

>>2355829

I already found your picture, no need.

>>2355843
here is a backup just in case
