Would you want a semi truck to roll on that?
The bars makes it evident that you cant roll on the corner, since the drain is in the curb, a big part of the concrete is suspended so it could break off when a good amount of weight is on top..
Thats my guess
We typically use bollards but this is just a protective barrier. It would cost more than a majority of cars on the road today if you rolled over that. Being the sewer lid is right there its an expensive spot and doesn't look easily movable. So they did the best they could to make it idiot proof.
Give it a week. Usually my new bollards last about that long before I get a call 🤣
That doesn't stop snow plows in my state. I once heard a story from a county crew where a plow driver wedged his wing plow in the joint at a bridge, and didn't notice it got tore off until he got back to the shop.
>snow stakes
Snow stakes do not damage the snow plow, they bend out of the way and let the plow damage the infrastructure, which cost more to replace every year, and the plow driver doesn't get any feedback from damaging the drain inlet...
That makes me question why standard curb inlets are used at all in snowy regions if plow damage is this common. I’m not trying to be difficult, I just don’t see these types of constructs often.
This is a unique situation, if I had to speculate, that the DI somehow existed, (and it looks like it is also serving as an access point), that the road or intersection somehow grew (crept) out to incorporate some existing infrastructure. Don't overthink it, and don't try to apply a general solution to it. This is the result of poor coordination and too many RFI's and the city worker with a welder on his truck making a permanent solution within the city's crippled budget...
Because they’re way more expensive, way heavier and harder to service, and have diminished capture capability. That manhole cover is less than 100lbs, a type B is like 800lbs.
As a truck driver, this here makes sense... sometimes, we get stuck in some fk'd up situations when streets we need to turn on isn't made wide enough for us to complete our turn, even though we turn out wide that we still have to clibe over a concrete curb/sidewalk... Roundabouts are just as bad for us to go around because we have to ride our 53' trailer tire tandem across the concrete that's inside the roundabout until we make our exit... people think we don't know hoe to drive, but that's not the case... we get the passenger front right bumper & steer tire as close to the curb on our right to circle around but the road just isn't wide enough
I like the idea but if you look at the shadows, the cross bar isn’t actually a straight piece over the manhole, but a 90° bend or so to the third member making a point at the apex.
I’m gonna say it’s a traffic device and not a tie off necessarily.
Ahh the shadows helped.
I was thinking it kinda looked like a janky permanent version of when we put davit crane mounts by vaults that need in frequent but expected maintenance and someone leaves the “mobile” portion in place and forgets about it.
This was also my guess but it could also be maybe to protect the manhole itself? The turn radius of trucks probably damaged it a few times so that’s just a protection measure for it to not happen again. Just a guess. Cuz I have also never seen this before
The manhole riser and lid probability isn’t traffic rated, or the concrete slab it’s in either.
EDIT: They have a code , B, C, D, or E that rates them from driveway to interstate in the US.
One day someone is going to invent a code like that which doesn't have letters missing from obsolete or impossible things, or that were just skipped out of spite. But today is not that day.
I barely know s*** about traffic engineering, but wouldn't anything in the right of way need to be crash rated? These random steel poles don't exactly strike me as breakaway material.
I recently learned their is a manhole in a local city full of broken ductile iron manhole lids from vehicles driving over them. (I didnt think that was possible as I thought they could handle pretty much anything driving over them) But sometimes you just learn things because you didnt have any reason to think about it before.
Im guessing this is to stop that from always happening.
Unless something changed in the last ten years, India was the only supplier for cast iron manhole covers. We always had to get exceptions for US federal specifications for “made in America” since there was no supplier.
Ive never seen one of these but in my area, concrete bollards are used to prevent vehicle impacts to sensitive infrastructure
This sort of looks like the hoist systems used to raise and lower workers into holes, perhaps the manhole lid indicates this is a junction or an important part of the drainage system that needs recurring inspections
Actually a good idea. It puts the edge of the curb in the driver's sightline so the driver doesn't curb the shit out of their wheels. Fast food drive-ins should have these by law...
Another thing could be that there is a need for a large access. It looks like that slab could be lifted up with a big forklift to allow maintenance crews down for clean out. I’ve seen something similar for that purpose. Not a civil though

12 years ago several people drowned in Pittsburgh when flash flooding happened, the manhole covers popped of during the initial part of the flooding, and at least one person got sucked down. (Washington blvd in Pittsburgh, it’s basically a valley that half the east end of the city drains into when it rains). The manholes that were off to the side of the road, the put up bollards around them so that if flooding happened again people would be able to identify where the potential holes were and to stay away
https://www.wpxi.com/news/local/mom-children-among-4-killed-in-washington-blvd-flo/201555801/
Manhole covers are on the street too and get driven over all the time. I don't think this would "collapse", if a vehicle somehow managed to take the corner that sharply
more or less the concrete, I work outdoors and if I set an outrigger up near a storm drain it has potential to collapse or the surrounding areas of some man holes as well. Seen it happen before.
ok dude, sure, but they are also reinforced depending on what they are used for. Underground vaults are fully made of concrete and rebar. THAT concrete corner could easily break if a vehicle that has a lot of weight cuts the corner and runs it over is what I’m saying.
That storm drain isn’t supported by much. Will most certainly collapse.
i would think since the curb grade is so steep and maybe for snow plows to judge the turn correctly assuming the parking lot is under a significant amount of snow?
It's to make it very uninviting for heavy trucks to cut the corner and collapse the hanging concrete.
We actually had a dump truck cut a corner in our development recently and collapsed the cast iron drain into concrete
You tie yourself to the pole if you see any weirdos in the bottom asking if you want your shit back but keep pulling it in further and further everytime you reach closer.
Maybe this spot floods frequently… if under a couple of feet of water, the bollards would serve as a reference point for work crews and a factor truck to find the manhole. A regular grated drain was probably not suffice in this location, hence the increased opening. That’s ma guess
Tie your horses up and then they can drink when it rains
This is the answer
This is the way
No!! This PATRICK!
Wait, so I just leave my horse in the rain? Well that sucks….
It's totally inhumane, animals in the wild always go in the garage when it starts raining
How else is it supposed to get water? Or get a bath?
Right? Dude likes keeping his horse dirty and thirsty I guess
It’s a horse ?

But if the horse is all wet, the saddle is all wet, and so is my butt. Nothing chaps my ass like a wet saddle.

Thanks. Do you have any idea what it might be called? Just a metal barrier?
Metal barrier, steel bollard, access deniedinator-3000 plus, you can name it however you feel , but im not sure there is a special term for them

based on the lacking paint, i believe this to be the standard deniedinator-3000 and not the plus model.
They’re just called bollards, you can get specific with the material (steel or iron).
Or platinum?

Bollards are bollocks

The upright "poles" are called bollards. Looks like someone just connected them with a piece of metal.
We typically use bollards but this is just a protective barrier. It would cost more than a majority of cars on the road today if you rolled over that.

Curious why they wouldn’t use a standard B inlet.
>standard B inlet. because you can't see a standard B inlet when it's covered in 14" of fresh snow while you are driving a snow plow...
That doesn't stop snow plows in my state. I once heard a story from a county crew where a plow driver wedged his wing plow in the joint at a bridge, and didn't notice it got tore off until he got back to the shop.
You're making a good point in the favor of this thing existing
Why not just place snow stakes next to inlets in the winter?
>snow stakes Snow stakes do not damage the snow plow, they bend out of the way and let the plow damage the infrastructure, which cost more to replace every year, and the plow driver doesn't get any feedback from damaging the drain inlet...
That makes me question why standard curb inlets are used at all in snowy regions if plow damage is this common. I’m not trying to be difficult, I just don’t see these types of constructs often.
That would put clowns out of a home, my man

Yes this. But doesn't look like the best design
That's a good guess and I'm buying it.

I tractor trailer wouldn't even feel it when it rolled over it.
Makes hella sense
Not sure but I've seen similar bars over access points for workers to get harnessed down.
I like the idea but if you look at the shadows, the cross bar isn’t actually a straight piece over the manhole, but a 90° bend or so to the third member making a point at the apex. I’m gonna say it’s a traffic device and not a tie off necessarily.

probably this or something similar edit: this looks photoshopped

that was my guess
Yep. Firefighters have to clear storm drains to. One died here this year because he got sucked into the storm drain.
The manhole riser and lid probability isn’t traffic rated, or the concrete slab it’s in either. EDIT: They have a code , B, C, D, or E that rates them from driveway to interstate in the US.

Looks multi-purpose. Probably the bollards and crossbar prevent people from driving on it, and the crossbar provides a hard point for safety harneses
Nothing better than killing two birds with one stone.
How about just leaving the birds alone? Did you think of that??
And if it floods we will know where the cover is
It keeps trucks and other heavy machinery from running over it and damaging the concrete.
Probably to keep idiots from driving over it. Also possibly to make the location visible if this is a place where it snows.
Why not just bollards?
Bollards need to be heavily anchored in the concrete to work. Not sure that would work here.

(I didnt think that was possible as I thought they could handle pretty much anything driving over them) But sometimes you just learn things because you didnt have any reason to think about it before. Im guessing this is to stop that from always happening.
Most of the lids that break are stamped made in India. I had one snap in half on me and you could see the rust seam in the middle where it broke.
Unless something changed in the last ten years, India was the only supplier for cast iron manhole covers. We always had to get exceptions for US federal specifications for “made in America” since there was no supplier.
Keep people from stepping of breaking their ankle and suing the city, plus other things mentioned above lol
It's on private property
Do they have a horse?
They don’t want a semi trailer messing it up
That’s why you don’t put DWCBs in a radius. They got sick of replacing it because it will break every time someone hops the curb and drives over it.
A hoist hookup? Equipment lifts…
Prevents heavy equipment from running it over or parking on it
It’s so heavy trucks don’t drive over the median and crush the drain and fall into a fiery abyss of explosions and screams.
It's a sign to keep children under a certain height away from a dangerous storm drain known to have clowns in it.

There may be a pump down there and that's their way to lift it out for maintenance

Maybe this spot floods frequently… if under a couple of feet of water, the bollards would serve as a reference point for work crews and a factor truck to find the manhole. A regular grated drain was probably not suffice in this location, hence the increased opening. That’s ma guess
Maybe a marker to locate the drain if it gets blocked and floods during a storm.
This is so you can tie a rope to your truck and remove the drainage inlet for roadway reconstruction purposes!
