underground container?

   / underground container? #31  
This school bus idea - it seems like a lot of work also. Wouldn't you have to take out the engine, the fuel tank, the wheels, etc? I assume they strip it and just lower the shell in or would somebody actually drive it into the hole?

That I don't know. I can find out what my buddy's dad did if you like?

I have a little trouble digesting that. They stack those things 10 or more high on ships and they get all tweaked around. I would think you could put it 4 or 5 feet under and drive a tank over it.

The weight of the containers is carried by the corner posts. 5 feet of dirt by 20 by 8 feet is a lot of weight. say 200 pounds per ft cubed = 160000 pounds

Edited to add ... granite weighs 165 pounds per cubic foot, sandstone weighs 150 pounds So dirt may weigh about 125 pounds

So ... 5 feet of dirt over the container is 100,000 pounds... roof is no match for that...

Concrete is ~150 # PQF so dirt is probably gonna be half that, plus what ever is over or near the sides is carried by the sides, not sure how to figure out how much weight would be towards the weakest part in the middle, but I can't see one built like mine caving in under 5 feet. Mine is close to 5,000 pounds empty, so it is not light duty. the continuous welded corrugated design is brutally strong.

I would like to see one put to this test, If I had to put money on it I would go with it not crushing, would I sleep in there? I don't know :laughing:

If I were putting money on it I too would bet against crushing, Collapsing is a very different story though. The walls and corners would very likely remain standing when the ceiling hits the floor.

So far I've obtained 600 8x8x16 new concrete blocks off of craigslist and I have a total of $100 invested.

I'd recommend going block. I wouldn't trust anything less.

It can and has been done, as have been discussed here.

However, the youtube video posted in post #11 is an excellent example of the following point (already made in post #20, BTW):

By the time you mitigate all the weaknesses of burying a shipping container, you could have had a bigger and better underground structure or a same size structure for far less $$$ if you had just started with the appropriate materials to begin with. To whit: concrete (poured or blocks), steel, fiberglass or plastic tanks (designed for burial) or even culvert.

The buses that were buried in Canada were internally braced prior to several feet of concrete being poured on top of them, these braces were left until the concrete cured. The curved nature of the school bus tops gave the upper concrete structure (along with steel reinforcement) to carry the dead weight above. In other words, the buses only formed the shell/mold for the concrete, the buses don't carry any weight, nor could they.

I just did a job where a container a freind of mine buried crushed. He had a hole dug in a bank then set the container in it. Then s lightly backfilled with a small tractor and loader. THe sides caved in then the top, the tractor never got on top of the backfill.

I had to dig it up and drag it out for them. He had 1500 in the can before the incident. I agree with others a buss with work with the round top. I have a friend with 2 in the ground just blocked the body up and tarred the out side and put it in a banks tieh oak boards over the windows. Im building a storm and rood celler in the future with block walls and concrete top and bottom

Shipping Container Building Engineering


I cannot find the exact link i'm thinking of from when years ago I was dreaming this idea up...but I do remember some engineers piping in and saying do NOT do it!

that aside, the first link above you can see that with proper side re-enforcement it seems possible....

Well, if I had some containers sitting around I might try it, but since I don't, I will go the route with block walls. When I get started I will be asking for help on the roof.

A friend of mine mother in laws house was flooded a few years back and to make sure it didn't happen again she had the home raised higher than enough to build a full size basement under it. When the masons laid the blocks they tied rebar from the footer [ and the footer was dug deep] and up through all the blocks. She then had all the blocks was filled with cement, I think that would keep the walls from buckling in, or just pour concrete walls all the way up. My front porch is high enough for a good sized room under it. I was lucky enough to be able to get railroad rails that had been used previously used in a secondary state road bridge. I placed them about 30 inches apart from end to end of the porch and poured about 8 to 10 inches of concrete over the top of them. I believe you could drive a tank across the porch and not cave it in. My front porch was poured over 30 years ago and there isn't a crack or a chip in the concrete, resealed the concrete this summer. These methods of building might be over kill for you but I know it will last. Hope you get the job done and it works out for you to your expectations.
