Hydrodemolition Robot Crushes With Water

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."

      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.

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.

      Take a basic class in macroeconomics -- this will explain it to you clearly.

      Your argument has been going on for centuries. One common incarnation of it was "Malthusian" economics -- in the 1700s Robert Malthus predicted that we would all run out of food if the population kept growing and people would die by the masses from starvation. He never accounted for the fact that we can make more food with more technology.

      How does it work, then? In a nutshell, seamstress gets replaced by a machine, machine puts her out of work, but seamstress can get a job as a machine operator. Machine makes more clothes then seamstress, thus she gets a higher wage (cutting out the Marxian labor value of theory, etc). Jobs are now availible for machine engineers, maintenence and manufacture, too. But the total number of jobs has dropped because all these people will not outnumber the number of people that were seamstresses and replaced.

      How do you keep full employment, then? Well, clothes are now cheaper so more people will buy them (supply-demand) making a need for more machines and more machine operators.

      Thus the answer is that you have to buy more stuff. Every machine that replaces people can sustain the current level of employment if people buy more stuff. That is why the economy has to be constantly growing at 2.5% per anum or else unemployment rises. You have to buy 2.5% more shit per year to keep unemployment low.

The "market" of available jobs and the "market" of available employees is sort of a lubricant for the economy, moving the right people into the right jobs.

      The first answer is that there is no difference between a robot (American Heritage, definition #2) and a complicated tool.

      The second, more complete answer is that a robot (WordNet definition from above link) is just an automatic mechanism. If you go to the AquaJet site (They're the hydrodemolitions company in question.) and poke around, or even just read the summary linked in the story, you'll see that the operator tells the robot where to go, how much concrete to remove, and how smooth to leave it, and the robot then decides (and executes) the proper number, speed and angle of sweeps with the proper pressure and oscillation. It doesn't mention what the second operator is for, but I suspect he's either back at the custom trailer mmaking sure the water lines feed out, or driving the reclamation truck behind the robot to suck up the water.

      The final answer (Well, the final one I'll be giving tonight) is that using the final definition of 'robot' on the dictionary.com page above ("A mechanical device for performing a task which might otherwise be done by a human, e.g. spraying paint on cars."), this is still a robot.

The company I worked for was by no means a "large" outfit, and they subcontracted out all the work to some people using a Flowcorp machine, then a team of our own guys would come along behind the maching and clean up the mess it left behind: digging out the rebar that didn't get cut free because the Flow crew didn't have the machine set right, cleaning up the mud, cutting the edges in (and sometimes a lot more because the Flow guys were trying to look as if they were on schedule...) etc. The most amazing part of that those machines could only come from a "bridge troll" like myself, working BELOW the bridge... Occasionally, the concrete of the bridge would be bad all the way through, and the pressure would tear right through the bridge instead of just down below the first layer of rebar. This was where you could REALLY appreciate the power of those water jets: something like a shotgun blast would go off, then shards of concrete would ricochette all over below the bridge, and the 5-6 guys on our crew would all be praising the powers that be that none of us were directly unde the thing. I somehow don't think that the designers of hard-hats ever thought that we might need to be safe from shot-gun blasts on construction jobs...

  94. State Inspectors by plnrtrvlr · · Score: 1

    You forgot all about the inspectors that the state (at least in NY) sends around to make sure that private contractors are doing he work properly... You can tell them apart from the workers, unfortunately, but on many an occasion, our crew (12 guys, "bridge trolls" replacing the suspension systems under the bridges) would be outnumbered by inspectors. We'd just shake our head realizing how bad that must look..

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

    That's the third time today I read about someone screwing up and the records being sealed. I'm really starting to develop a distate for the entire notion of sealing court records.

    I'm sure someone can come up with a good example of why and when court records should be sealed, but I really don't want to hear it at the moment. Let me have my little daydream of a world where it's illegal to seal records, a world where the birds never splatter poop on my car, a world where slashdot won't run three more SCO stories in the next 24 hours.

    They can settle out the water that gets sucked up with the rubble, filter it well, and reuse it. They can also filter untreated ditchwater.
    Now, something like this would never be permitted around here (front range region of Colorado, USA), as the water supply would be a barrier. Our water laws are some of the most complex rules since the fall of Byzantium, and the supply is tight enough that nobody'd ever let them use water for such a purpose, even if they got the supply.
