Why are manhole covers round? - GoFuckYourself.com

Please discuss.

Dildozer · 05-21-2003, 02:17 PM

so the manhole cover doesn't fall in the manhole

if it was squared or rectangle it could fall down there, imagine the shit people could do.

NetRodent · 05-21-2003, 02:18 PM

Um... Because manholes are round?

1. So they won't fall through the hole
2. So they will roll

1. is incorrect.
2. is one good reason . . .

Manholes, which interconnect underground sewerage pipes, and serve as a point of entry for cleaning the pipes, are located at every major sewer pipe junction, and are capped with round manhole covers. The reason for the circular construction of these covers is, quite simply, that covers of any other shape would fall through the manholes by virtue of their varying diameters. Circular manhole covers do not vary in width, or in diameter, as is the case with these other shapes, thus remaining in place despite the street traffic running roughshod over them.

Manufacturers craft the manhole covers together with the smaller sized lip, upon which they rest, at the same time to ensure a tightly sealed fit. Additionally, the manufacture of circular manhole covers is easier and more accurate than the manufacture of covers of any other shape. Lastly, round manhole covers, once removed, require less lifting and less manpower, as their shape allows them to be rolled.

also, Round covers can cover holes no matter how they are oriented vis-à-vis the hole.

EDIT: See, you got your answer form the same place I did, yet you told Dildozer that he was incorrect. I vote that he should be given the opportunity to beat you to a bloody pulp for it.

So Dildozer was essentially correct.

Now for the more important question: Who really gives a fuck?

I got into this discussion about 2 weeks ago with an engineer. He was taught the same thing I quoted above about 20 years ago in school.

It's wrong.

you might want to look into this a little bit . . . before you start calling people names

John3 · 05-21-2003, 02:39 PM

Let me re-phrase . . .

It is not correct to say that manhole covers are round because "it won't fall in the manhole".

carry on . . .

Helix · 05-21-2003, 02:43 PM

as long as the manhole cover diameter is greater than the man hole, it is impossible for the cover to fall thru the manhole.

stocktrader23 · 05-21-2003, 02:46 PM

Because the manhole is round silly.

So why are pipes round?

gothweb · 05-21-2003, 03:59 PM

There is a sublime simplicity to anything round. I assume that for a variety of reasons, pipes, manholes, etc. are round due to this simplicity.

More specifically, I like the following reasons...

1.) It can't fall in because the diameter is the same everywhere.

2.) It is easy to replace a manhole cover, because you don't have to rotate the heavy cover, it fits at any orientation.

3.) Moving heavy things is easier if they can be rolled.

More cynically, I suspect they are round because someone made them round once, and then it was easier to keep doing it the same way. That's how most standards arise.

Standardization.
You and I think alike.
