Home Forums Hunting & Shooting Hunter's Campfire Oroville aux spill to fail within the next 60 min!!

Wow... Didn't know there were so many structural engineers and groundwater hydrologists here... I'm learning a LOT!

So everybody here deserves to die?

Refugees without access to their EBT card! Dayammm, when I think of California babes - it ain't that...


Rebar fubar

Slabs for everyone.

Cross there was one picture that when viewed up close you could see the rust lines where the rebar was.

It did not have any pieces hanging out but it looked like the concrete delamanited or something.

Seems they need to redo their inspection process some.

Lol. Between funding ebt, tranny bathrooms and Eric holder there is no money for infrastructure repairs.

Don't forget the wildlife bios and ag economists... And Political wizzers and conspirists...

Darn, I did forget those...

And, the "BA's" in "Environmental Science"....Gawd, that [bleep] cracks me up!!!

and boycott mavens!!!

Not good ones.

To me it looks like it should be a "tub" instead of two walls poured with the spillway poured after. It leaves a lot less room for error.

We done just use da leftsover chain link fence, that's all da governer would gib us. Don'ts needs no spilzway nohows tain't rained cents fo'three..










Two minutes I'll not get back.

Lol. The link fence reinforcement looks reusable! Quikrete dumped in the hole should cure before the next storm. F ucking engineers no dik.

The average man's hand stretched out spans about 10 inches. Look at the top photo. That slab is a bit more than 8 inches.

How thick? 30"?



It's a big un.

FAKE NEWS WARNING
https://wattsupwiththat.com/2017/02/09/ororville-dam-spillway-collapse-may-be-due-to-missing-rebar/

.....

If REBAR was present, we likely would not see such a dramatic collapse as it would have prevented water pressure cavitation from eroding more and more concrete. Concrete is a material that is very strong in compression, but relatively weak in tension. To compensate for this imbalance in concrete’s behavior, rebar is cast into it to carry the tensile loads. This means concrete pulls apart much easier than it is crushable, but with REBAR the tensile force required to pull the concrete apart is greatly increased.

One wonders if that lack of REBAR on the spillway was by design, accident, negligence, or some cost-cutting measure like the lack of life-boats and cheap steel on the Titanic. REBAR in concrete was invented in 1849. It seems incredible to me that it seems to be missing from this very important structure.

It is a might thicker than 8", thanks for the better pictures.
Appears to be slab and beam? More substantial then the video I saw, for sure.

Problems at the Oroville spillway were known.

A picture shot by Lois Cameron from 2013 shows crews examining an issue around the area of the current hole.

“There were some patches needed and so we made repairs and everything checked out,” said Kevin Dossey, a Senior Civil Engineer with the Department of Water Resources. “It looked like it would be able to hold, be able to pass water.”

Dossey says this sort of thing is routine.

“It’s common for spillways to develop a void because of the drainage systems under them,” said Dossey.

While everything may have appeared normal back in 2013, 2014, and 2015; what happened Tuesday when the earth gave way, is anything but.

“There wasn’t any evidence that anything more needed to be done,” said Dossey, “repairs were smooth and looked like they were good and secure.”

Complete ignorance on the location, but will snow melt affect that water shed?

Yes

Part of th problem was rain melting snow

They have a good snow pack this year too, correct?
