Using a remote control pack, Bryan DaMoude of DaMoude Concrete Pumping of Hershey, left, directs the pouring of the foundation for the new urgent care walk-in medical clinic on North Highway 83 in McCook, under threatening skies early Wednesday morning. The crew from Hard Core Concrete and Construction of McCook -- which included, from left, Greg Brennan, Lirin Yost and Thursday, April 30, 2009 Heath McDonald -- spread the concrete in preparation for floating and finishing. Funneling concrete into the concrete pumper was Dave Maynard, of Gerhold Concrete, also of McCook. The developer of the new clinic, Jim Allen, a physician assistant, watched from the sidelines. The clinic will offer minor medical assistance on a walk-in basis, and will be open from 7 a.m. until 7 p.m., six days a week, and five hours on Sunday. Hours may be expanded if necessary

kind of looks like on of these

 Judging by the way the story was worded it must've been an article or something that you repeated?

 Why that's a concrete shower head. So when the pump takes a gulp of air and whips that DE hose around it evenly distributes the mess and showers everyone in the area with concrete! That way no one is left out. They work great for shutting down the entire pour...  

 Hell I dont know, It looks like something totally brilliant though. Lets wrap it with foam and call it a "boxing glove". Hmm, where have I heard that before?

wow! just...wow!

I think i am going to call them but i am a bit worried they will chew my butt. lol

I've seen these before. They call them difussers, I sure as hell wouldnt use one but I know a former company I used to be affiliated with used them in Nebraska. Same color booms as in the picture. I believe I was told way back when that they are used because of the mixes there. The discharge end has two pieces of steel crossed (like a railroad sign), when the mud hits the steel it sorta mixes it. I only saw one on the ground, when I asked "what the hell is that" that was the answer I got.

I bet some operators from the Colorado area could explain it better, probably from experience.

first three patiants will be rolled in shortly .

looks like a concrete sprinkler.

if the contractor absolutely has to have that thing on, i think the best way to do it is with a stubby hose (less swing) and no hose man. otherwise, F- that man. i wouldn't put my livelihood at risk for a couple hours of work.

On the bright side at least they are at a medical treatment facility if the need arises.

Diffuser is the terminology and used to place concrete withouth boiling up loose sand when pouring.  Inside the cylinder is a cross of steel and on that a 2"-3" tall cone that is hard surfaced.  Concrete, in theory, hits the cone and is pushed to the outside cylinder and then to the ground without as much downward force with greater placing speed.  I used one for probably 15 years but have changed my ways recently and use a reducing hose.  You have to slow it down a lot more with the hose but the guys do realize the safety factor and don't complain too much.
