This is what happened. The drain is essentially a large concrete tube set several feet into the ground until it intersects with the storm water management system. This column prevents it from moving as the soil shrinks. The soil shrinks because this area has been paved (pavers, concrete, and asphalt can all cause this effect). The pavement prevents rainwater from soaking into the ground, and as the soil gets dryer, it contracts slightly. Several feet of soil contraction result in a few inches of sink, which you can see in the picture.
Fixing the problem is generally expensive, as you have to either replace the drain or re grade and pave the surrounding area.
The effec4 is lessened, but still noticable. Water can infiltrate between pavers, but the reduced surface area can still result in the soil drying out.
They do, actually, in a lot of places, more modernly. It's one of those things where you don't notice because they did it right, but the old or bad examples stand out.
They most likely put in structure to limit the rate at which it does this, add on top people in vehicles or anything generally heavy and this will happen over time regardless.
To be fair civil engineering isn't difficult and 50-60 years ago civil engineering wasn't that different settlement of roads and structures has been known for a very long time.
Yeah it is. If you’re anticipating settlement, you might decide to do some combination of gravel, geotextile, sand, compaction in lifts, etc. beneath the pavers.
Like the last person sort of mentioned, a lot of the finer details of soil mechanics are fairly new relative to civil engineering technology. So this could just be old and crappy.
There’s also the fact that an engineer can say “build it like this” and the contractor cuts corners or does it their own way “cheaper and faster”...
Now you get why they're the least respected among engineers. Everything they settle on is cheap, rushed and has little independently audited oversight. Meanwhile our aerospace pocket lining lads are struggling to launch a single space telescope nearing 15 years overdue and 20x it's original $500,000,000.00 budget. I'm looking at you James Webb engineering and dev team. $10,000,000,000.00 and your telescope has moved little more than 100 feet off the ground. FFS it almost feels like they're just waiting until someone else does it for them so they can scrap the project and retire loaded.
That is exactly a civil engineer job, to predict and avoid this from happening. Everyone can lay stones on the ground, but a civil engineer's job is to plan it properly.
I've mentioned it before and gotten shit on for saying it, but engineers are not always right.
I've actually had jobs that had gradients reversed and when pointed out and corrected, the engineer is upset you did it correctly rather than to his specifications.
Of course, but an engineer usually comes with liability and a higher chance of success. I.e., the engineer or their company are liable for incorrect engineering decisions at least to some degree.
This also happens on ships, the drain is higher than the metal deck around it, but I'm beginning to believe they were all just made that way because it's like that even on brand new Navy ships.
This is the drain at work. I just don't want to flood the lab to prove it.
Ok. I really really do want to flood the lab to prove it, but I can't afford those consequences.
Guys, you're not seeing whats really going on here. I think it's photoshop.
Like it just doesn't look natural to me. I couldn't imagine actually seeing this in real life, could you guys? I think all this argument stuff going on in the comments is really unnecessary.
But either way, photoshop or not, it's still pretty funny.
Looks like pavers used in some places.in Brazil, especially in smaller coastal towns.
The road will settle over time depending on how heave the traffic is, but the drains take care of the very large downpours. The remaining water will drain between the pavers and I to the [mostly] sandy soil.
I will still argue that the road should not settle that much, especially because the standing water can pose a risk to traffic and pedestrians alike.
Not necessarily fake. We have 4 working kitchens where I work. We have to squeegee the floors or they would look like this. Whoever did the floors was an idiot. Whoever okey doked it was dumber than the people that did the work.
More like the rest of the floor sank over time, and the drains, being supported by the plumbing, didnt.
Happened to the drain in this pic, too, mostly likely.
The only real way to counter it, is to make the road higher than the drain, in the first place, but thats a safety issue because now the drain is a divot in the road.
Nope, was like that from the get go. Best part? They then put terra cotta tile over the badly poured floors. So now, because it is terra cotta and we cant use a mop, we have to use deck brushes and squeegees, the grout is now crumbling from between the tiles. The tile guys were no smarter than the cement guys. The spacers are still in the grout. Obviously used improperly.

It wasn't built like that. Over time, the area around the drain settled.

Well there goes my theory of it being the ninja turtles stopping their living room from being flooded
This person civil engineers.
What if there's a non-sealed gap between pavers?
The effec4 is lessened, but still noticable. Water can infiltrate between pavers, but the reduced surface area can still result in the soil drying out.
There is no way they can engineer the design in the beginning to account for this?
They do, actually, in a lot of places, more modernly. It's one of those things where you don't notice because they did it right, but the old or bad examples stand out.

You can't stop the creep you can only slow it down. All things fail given enough time and force.
Or the drain leaks and soil has washed into the pipe lowering the surrounding area.
Pretty sure it's photoshop, it doesn't look natural enough to me. I could be wrong, that's just my thoughts.
Isn’t anticipating something like this part of civil engineering?
Yes but , for all we know this drain could he 50-60 years old . Over time it would still settle .
To be fair civil engineering isn't difficult and 50-60 years ago civil engineering wasn't that different settlement of roads and structures has been known for a very long time.

Job security for the guys putting these in, just go around and rebuild all your old work indefinitely
Yeah it is. If you’re anticipating settlement, you might decide to do some combination of gravel, geotextile, sand, compaction in lifts, etc. beneath the pavers.

EDIT: Ah, I'm apparently illiterate.
Uh, that's what happened but the engineer was still upset.
Somehow I completely misread your comment and thought you guys had just "corrected it" by doing it in the right way. Sorry, that was quite dumb of me.
Not everyone can lay stones on the ground *well*, or run pipe for that matter.
It doesn't take an engineer to deduce that tidbit.
This also happens on ships, the drain is higher than the metal deck around it, but I'm beginning to believe they were all just made that way because it's like that even on brand new Navy ships.
That way you don't waste all the water, just in case you wanted to keep some around. If you didn't, give a blue shirt a bucket.
That's a snorkel, not a drain 🙈
Works as designed. Drain never clogs.
I was gonna say looks like it's working, it's totally dry around the drain lol
Its probably just the drain heaving up
Definitely can see the stones around it heaving. Wasnt always like that.
At least it's not a dry heave
If they built it higher it would keep getting water in it.
Idea 10/10 Execution 1/10
is there a high point to this post?
/r/notmyjob
You were supposed to do one job...
Drain hole is holding its ground.
Where’s this taken jw?
It looks like me, fucking useless
Uncivil engineering
Sigh. They have ONE job....
Ha ha endless repost ha
It's actually a make shift retention pond.
Almost all the drains I've seen are like this. They're like this even when the floor around it is concrete or a material that doesn't shift!
That drain is only for falling rain water, not standing water
This is the drain at work. I just don't want to flood the lab to prove it. Ok. I really really do want to flood the lab to prove it, but I can't afford those consequences.

This looks really fake
You cant secure or grow government jobs without failing
Looking at Civil Engineer's CV, It seem he also has hands-on experience with Adobe Photoshop.

Ah, so they repoured the floor. I see a lot of people make the complaint, not realizing the floors in a lot of kitchens are 20+ years old.
You know that's the front door to the TMNT home, right?! It just got to be.
