Hydrodemolition Robot Crushes With Water 292

Posted by simoniker

Roland Piquepaille writes "In 'Robot pummels roads with water', the Augusta Chronicle says that a hydrodemolition robot is going to restore seven bridges in Georgia. "It's a robot that destroys everything in its path with a crushing stream of water 15 times more powerful than a jackhammer. The robot looks like a street cleaner machine on steroids and is expected to begin use August 1 to resurface seven bridges on Gordon Highway from Walton Way to the bridge at the South Carolina state line." This kind of robot needs only two workers to operate it, instead of 15 workers for a jackhammer, is less noisy and more gentle for the foundations. You'll find more details in this summary."

        Don't you pay attention? Whenever you have contstruction work going on, you always need 3 or 4 guys on a break. If you don't have 15 workers, you can't keep that many people on the break. It's called rotation!

        Having been on a crew that used one of these exact machines, it is indeed potable water.

        The magic is that it uses 35,000 - 50,000 psi and through a very tiny (.035", IIRC) nozzle. Very low flow, 20 gpm or so.

        Actually, only about half of the water remains to be reclaimed - after the trip through the nozzle and all of the friction with the concrete & rebar, about 1/2 is lost as steam. helluva thing to watch.

        As for the '15 men' comparison, here's my first-hand experience:
        We used men with jackhamers to remove the first two inches of concrete (down to the rebar)
        Crew:
        (1) operating engineer - man the air compressor. He's frickin' useless.
        (1) laborer foreman - push the men, repair the extra jackhammers, rotate into the crew
        (5) laborers - constantly on the hammers. (unless too many broke down. We had seven hammers, and about 5 runing.)

        The robot is used to remove concrete _under_ rebar. The rebar comes out looking sandblasted - bare white metal. That's the trick that would take 15 men with jackhammers. The crew there was a robot operator and a guy at the pump. Actually, the laborer crew was cheaper than the robot.

        Also, the other thing these things do real well is scarification - roughen up the surface before you put down a top coat. The other good way to do it is with sandblasting, definately nastier than hydroblasting and worse results to boot.

        Basically these things rock.

      To give you context, compare that to the software world, where 'about two' translates to just you, 4 weeks out of the 20 week projection, a pissed off laptop, and a boss that lives and dies by metrics.

    I remember way back when I heard of something very similar, except it was a type of "saw" where extreme water pressure was used to cut wood (and possibly other objects) nicely in half. Apparently it can be quite a nice cut, without the friction-burn of metal blades.

    However, that is in an environment where the water can be recycled to a good extent as the machine runs... where does this machine get water from, and how many PSI is it dishing out? I'd assume that it requires close proximity to a good source of water, either a fire hydrant or (preferably), a lake/river/etc - as it probably shoots out a lot of water in order to achieve the correct pressure.

    I was going to re-read the article and double-check, but the blink tag at the end of the linked tech review just about blinded me.

      You heard right. For anyone who hasn't heard of this there are several kinds, basically broken up by the maximum pressure. When I was involved with building automation systems this was one of the coolest things to play with (though they aren't toys).

      Add a little pulverized rock into a 0.012 inch stream of water at 60,000 psi and you can cut through *anything*. Biggest thing I ever saw was a 17 inch thick slab of titanium plating. The edges end up smooth, cool (or at most warm to the touch) and, if you are cutting something really expensive (or toxic) you can reclaim 99.99% of the material you eroded away.

        I dont know what you were looking at but I was a waterjet engineer a decade ago and first off to cut something like Ti you cant use water .. instead you use cerium oxide which is sucked into the water stream stream. So now you are using the water to accellerate the cerium oxide rather than teh water itself to cut. Also when you add artifacts you cant maintain a clean stream for 17 inches, heck with out artifacts a 30cm stream is amazing (water at 30-75k psi has to be very clean or you will destroy the nozzels almost instantly) its because of the problems with laminar flow. When the water hits the diaphram of teh jewel its pressure is so high that it acts like a laser in that only the water moving perpendicular to the jewel surface can make it out so all the water is moving in exactly the same direction, this is called laminar flow and the idea was developed by Dr Bob Higgans decades ago (he was a steam engineer originally to give you and idea of how old he is). Long story but Flow is evil they did some nasty dirty things to Bob and he formed his own co Technicut (whome I worked for). Anyway back to laminar flow, you see teh edges of teh stream after leaving the nozzel will cause air turbulance and start to tumble disrupting the stream. Eventually turbulance invades the entire stream and it looses most of its cutting ability. Now concrete? well thats easy to cut with straight water because quite honestly it is pretty soft. Of and you cant inject cerium oxide in a number 1 jewel ( .01 inches) you use at least a number 8 and preferably a number 10. Actually i guess you would ne mentioning a number 2 jewel which would be .02 but since the diameter of the stream is only 60% of the diameter of the jewel that would make it .012 still not enough to transport the cerium oxide.

        • Why the hell would you inject cerium oxide above the orifice when you can just entrain your favorite variety of abrasives into the beam below the jewel?

    Last decade, in Washington State, hydrodemolition was used to "resurface" the Eastbound lanes of the Lake Washington Floating Bridge, a couple of miles from the Western end of Interstate 90.

    Due to a chain of snafus, the "floating" bridge sunk one Thanksgiving day. Very nearly sunk the brand new Westbound floating bridge right next to it. (Part of the root cause was the storage of hydrodemolition wastewater in the flotation cells of the bridge.)

    Some years later, the records of liability were sealed in a court settlement between the state and the contractor.

    This story reminded me of how when I was a kid (about 6 - 14 or so) I would take the garden hose and one of those gun-shaped attachments to my mom's garden and explore the excavatory power of water.

    At one point I had a very large system of trenches about a half foot deep dug through the flowers that went on for quite a distance.

    Needless to say, the local authorities (mom) weren't thrilled with this "science." They all said I was mad. They called me crazy. er...

    I think one day being employed is gonna feel like a scramble to stay ahead of some impending hyper-mechanization boom. yeah, it's been happening for at least a hundred or so years with basic, non-skilled labor, but what about highly skilled labor? what's going to happen with a robot can take orders from management to design applications faster and better than a human?

    Whoever posted the article seems to have misinterpreted what the article said. The article says:

    "One hydrodemolition robot does the work of 15 jackhammers." "Requires only about two workers to supervise it instead of 15 jackhammer workers."

    Specifically, since the robot can do the work of 15 jackhammers, you don't need those 15 jackhammer workers operating the 15 jackhammers (i.e., one worker per jackhammer), and can instead rely on the (about) two robot supervisors.

    Perhaps I am one of the few Civil Engineers who find myself reading /. So +karma to the editors for bringing this article. I still would like to know how it removes the concret and doesn't dammage the rebar. When you start getting aligator cracking in concrete roads, water has more than likely reached the rebar, rusting it. Some newer road specs require that the rebar be coated with epoxy. This cuts down on rust, and may allow for rebar reuse in the case stated with the article. --C. Alan, PE

  • How did the DOT get around the unions with this? Certainly going from 15 union guys to 2 union guys can't be what the union would want.

    Alright, I'm sure someone has the answer to this... what makes this thing a 'robot' as opposed to say... just a big fscking tool?

    I mean, it still takes to people to operate it, so it's by no means autonomous.
