As my watchers already know through my incessant complaining, we've been hauling concrete around the clock since Monday morning. Obviously I haven't been working 24 hours but I haven't had a day under 15 yet...and this is day 5 with 3-4 more to go. It will run all through the holiday weekend and likely finish up Monday evening. Thankfully Sunday and Monday are doubletime. When you're cranking out 105 hour work weeks, 30 of which are doubletime and a ****load of time-and-a-half, it tends to quiet the complaints a bit 
Oh, the drivers are working three 8hr shifts, btw. We aren't running them nearly as many hours as the owner and I are working. That would present some serious safety issues.
Anyway, the project is two new raw coal silos for Consol Energy's Bailey Mine. It's a slip-form pour which means it has to be continuous...no stoppage from start to finish. The way slipform works is really cool. The cylindrical wall forms and scaffloding are built with a lift attached to them. The lift moves at approximately one inch every 5 minutes. Concrete is dumped into a pump which pumps it up into the top of the form. As the concrete sets up, the form continues moving upward. Obviously we use some fairly intricate mixes and admixtures to make this happen (mostly for set-time control), along with strict concrete temperature control (also set-time related), but it's really not that hard once you get rolling.
Anyway, if I haven't painted a good enough picture to describe how it works, just check out the Facebook photo album that I've been adding pictures to.
The last pic was approximately the half-way point. The total height will be 205'. |
