Wolve,
The one thing that I am positive about around here is that all you guys type faster than me.
As to the geo bags, I have watched that video of their operation, both from the manufacturer and the site several times and the bags do not appear to me to operate in a continuous fashion, but rather they require a cycle time in which they are filled up with the slurry to a set volume and then allow to draw down. In some of the videos that I viewed last year, the process was demonstrated where the bags were rotated through, one at a time, filled to capacity, then left to drain as the valves were switched to the next bag.
If there are six bags in service, it would be my humble opinion (as a general engineering contractor for 24 years) that there would be sufficient redundancy in the rotation to take one of the bags out of service at a time in order to affect the maintenance.
Heck, if you look at the quantities involved, 1,000 Cu. Yds. Per Day (Shift) that’s the equivalent roughly 100 fully loaded concrete mixers. The geo bags are half the size of a football field (160 feet long if I remember right)
If, I remember right, Dakota Fred said that his wash plant took 300 gal. per minute. That’s 144,000 gal per day or 19,200 cubic feet per day. That’s the size of a regular swimming pool. If PCFG does 3 times that water flow that is still filling 1 bag per day and then letting it drain down.
What I’m getting at is the redundancy is there with the 6 bags and the other 4 are for expantion or a second shift.
I got to get out of here and get to a job walk,
