Ha! It looks like a giant suppository.

Holding back pressurized water is one thing. I wonder if it will stop storm surge which is lots of water, moving quickly, filled with lots of junk.

Cool idea though, but I would want to see test data first before major investment...

Really? You don't want them to spend millions of dollars producing these things to find out they don't work later? Revolutionary thinking.

Just about the right size to fit Subby's Mom too... might still need a few more PSI to hold it in though.

Q-What is something most people have encountered plugging up surges of water in pipes.
A-Tampons.

Get a large plug that asorbs water and gets larger when made wet.

Giant tampons for giant tunnels.

/I think this was designed in Japan.

Well I can tell you from first hand experience it would be helpful but probably not enough.

I live literally yards away from one of the primary towers on the Holland Tunnel on the Jersey side. I sat here and literally watched as the surge flowed over the rail along the Hudson, consuming that tower, and most certainly racing down the air exchange pathways directly into the tunnel.

Securing the entrance is one thing... securing EVERY possible entry for water is something else...
 
2012-11-02 10:24:03 AM  
It is just me, or is this idea laughable. Trying to keep water from flooding an underground maze of interconnected tunnels, each with countless access hatches, leaks, sub-tunnels, etc is pretty much the definition of a fool's errand.

Trying to secure one particular tunnel from a potential gas leak or airborne radioactive material like from a dirty bomb is one thing, trying to keep an entire subway system from flooding is quite another.

But what do I know.

Are they going to test them on Octomom?

That's kinda what I thought. Trapping in fumes that could ignite. One spark, ka-boom!

How do the plugs deal with non circular openings, like subway stations.

These do not appear to be designed for the stations. Just the tubes.

By expanding.

Put a balloon in a square opening, and inflate it. See what happens.

Yes, that looks like it would help keep the subways regular

it mostly filled it, but left the corners open. whats your point?
 
2012-11-02 10:34:43 AM  
You will need hundreds and hundreds of plugs. Think of all the vents and access tunnels and escape hatches along the way. There are hundreds of openings. You could possibly put airbag like things in place at all of these, but its going to take a perfectly accurate survey of the system to start, including all the abandoned tunnels that connect to the main system.
 
2012-11-02 10:34:59 AM  
This is great excpet they already ahve to have pumps running 24 hours a day to keep the water out when there isn't a hurricane, so I don't really see how these things are going to help once the power goes out and the pumps fail.
 
2012-11-02 10:36:23 AM  
On the plus side - even if this costs $100 million to implement, it's probably less than the damage caused by a couple of good hurricanes.
 
2012-11-02 10:37:17 AM  
Installing some more pumps might not be a bad idea either.

Accidentally over inflate it and you crack the tunnel.

Next, government funding will be used to develop barn doors for people who have lost horses.
 
2012-11-02 10:47:48 AM  
So you plug the main tunnel. You still have service tunnels, doors, vents, fans, and cracks. Most tunnels have to be pumped out on a continual basis. Guess what happens when the power goes out?

Nope, they're going with a professional.

They have river dams that are inflatable. The hold back a terflop of gigagallons of water and debris.

Pa. has one 2,100 feet long.

Surely you could jam one into a subway.

Well you don't know how to get a government contract that's lasted for 5 years and has come out with ONE plug that costs $400k.
 
2012-11-02 11:02:09 AM  
With Mother Nature giving us crazy weather, those tunnels will probably have to be plugged up every month..

Will there be extra slim models for different size subway tunnels?

2012-11-02 11:28:40 AM  
Well, I suspect one could deal with the issue of a debris puncture by using, say, multiple inflated layers.

To those saying "But there are thousands of entrances to the tunnels", the way I envision them using these is, say, have one every X feet in the tunnels. (X might be in the hundreds of feet? Dunno). So, when you seal everything up, you don't just put one seal at the beginning and end of the tunnel: You've got multiple seals, breaking it into sections.

*Some* of those sections will probably flood (Based on the aforementioned various other entrances, etc), but not all of them-so it will, at the very least, minimize the damage?

That is, assuming they deploy them that way.

When you're building a new major sewer line to connect to an existing major sewer line this is the sort of thing you do to keep the shiat out until your project is done. I don't know if it would work in a subway tunnel for reasons mentioned above, i.e. more than one hole to fill.

As far as complaints about porous subway infrastructure.

If you somehow block the water from draining to the tubes, where does it go topside?
 
2012-11-02 11:34:01 AM  
Wasn't drowning all the rats, homeless people and supervilians living in the tunnels a good thing?

Why not? How would that be different from any other government project?

2012-11-02 11:42:14 AM  
So how well will they hold up after multiple inflation and deflation cycles? And what's the shelf life where they can sit in a warehouse or on the subway wall before needing to be replaced because it won't hold air anymore?
