Easy, you make a tunnel underwater, get some sponges and get rid of the water

[–] tomiant@piefed.social 9 points 19 hours ago (1 children)

I work with these tunnels and while I am not involved directly in their construction I can say that it takes quite an effort going through all the nooks and crannies and stocking supplies in crates and locked containers like ammo, anti radiation pills, random junk, low tier armor, and fruit that never goes bad.

But who keeps the candles lit?

It's even worse when you take the time to learn how they're made, and then you realize just how very far you are from being able to even comprehend the basics of such an operation. The amount of money, time, equipment, resources and training for something as simple as a goddamn overpass is staggering.

Our whole system is so incredibly complicated and fragile that it's reassuring at least we pick the very best, smartest and most qualified leaders to manage all this.

Wait, I'm being told that we do the exact opposite of that. Welp.

it's reassuring at least we pick the very best, smartest and most qualified leaders to manage all this.

Reminds me of that episode of Futurama: "Fortunately, our handsomest politicians came up with a cheap, last minute way to combat global warming."

It's actually really fucking cool, for ones like this they cast them in concrete sections, seal the ends, float them out, and sink them into place! Practical engineering made a video about

[–] statler_waldorf@sopuli.xyz 57 points 2 days ago

My dad's a retired civil engineer and I got to see how all this worked when he did one back in the day. I got to see the individual sections being built and then got to walk through the tunnel after the sections had been connected and before they were ready for traffic.

This one?

I didn't know about this tunnel, but I imagine other ones are built by actually digging under ground right?

[–] pixeltree@lemmy.blahaj.zone 14 points 2 days ago

Different strategies for different situations!

“Hey you!”

Me?

“Yeah you. Get over here and build this tunnel.”

*picks up shovel

[–] SpaceCowboy@lemmy.ca 10 points 2 days ago (1 children)

Actually not too far from how they built tunnels in the 19th century.

Hmmm.... water is leaking in that one, shut it down get out the shovels again and we'll try to build better one that doesn't leak.

You there, stick your finger in this dyke!

[–] Bytemeister@lemmy.world 6 points 1 day ago (1 children)

You can't just say stuff like that.

[–] JackbyDev@programming.dev 5 points 1 day ago (1 children)

The fate of the town depends on it!

[–] HeyThisIsntTheYMCA@lemmy.world 3 points 1 day ago (1 children)

I'm gonna need more fingers cap'n! i'm givin' her all i've got!

Would you really shove all your fingers & toes into a lesbian??

[–] JackbyDev@programming.dev 3 points 18 hours ago (1 children)

A- a lesbian? My friend, there is a failing piece of infrastructure!

[–] LemmyKnowsBest@lemmy.world 3 points 17 hours ago

But your double entendre game was so strong!

[–] starik@lemmy.zip 30 points 2 days ago

That’s the great thing about our species. You never have to do it alone or figure it all out for yourself. Just following instructions will get the job done, and if you contribute an incremental improvement to the process, you’ve gone above and beyond.

It's only a matter of time before someone has to fly a fighter jet through this to stop a nuke launch.

[–] Test_Tickles@lemmy.world 6 points 1 day ago

I'm glad they started putting up No Helicopter signs at the entrance to the tunnel near me. I think the local henchmen got so used to chasing people through them that they would sometimes get distracted and absent mindedly take the tunnel on their commute to work.

[–] Syndication@lemmy.today 2 points 1 day ago* (last edited 1 day ago)

I imagine lots of people did this in GTA V lol

[–] slazer2au@lemmy.world 24 points 2 days ago (3 children)

Easy, you buy a really big machine that goes brrrrrrrrr

[–] CelloMike@lemmy.world 32 points 2 days ago* (last edited 2 days ago)

For rectangular ones like this they often build it on shore as a big metal tube, and sink it into the water afterwards

[–] flamingo_pinyata@sopuli.xyz 10 points 2 days ago (1 children)

Yes the brrrrrrrring machine

[–] ceenote@lemmy.world 6 points 2 days ago* (last edited 2 days ago)

Specifically the model that brrrings tunnels to the sea floor.

[–] Lembot_0006@programming.dev 6 points 2 days ago (1 children)

This machine even is called brrrrrr or borrrrr or something like that.

[–] bleistift2@sopuli.xyz 11 points 2 days ago (1 children)

Fun fact: The word ‘boring’ comes from the tedious work of drilling a hole by hand.

[–] Zachariah@lemmy.world 5 points 2 days ago

it’s boring work making those tunnels

[–] devfuuu@lemmy.world 15 points 2 days ago

It was aliens. We clearly don't have the technology so the ancient people who created this obviously had external help. Have you seem how huge these blocka are? Insanity.

[–] ivanafterall@lemmy.world 5 points 2 days ago

Stop trying to get out of it and grab a shovel already.

[–] ieatpwns@lemmy.world 4 points 2 days ago

There’s a group in Brooklyn who might be able to help you out
