I need some advice on my bin(that I've been building for the last two years
)this morning I moved the last 1.5 tons of coal out of the area I want to put the bin It's a corner of my parking area(base is 4" of 304 vibratory rolled and topped with 4" class C concrete with wire mesh) I have had 6 tons of coal on it but in a area 11'x11'.
The bin I want to build is cinder block 112"x112" on the outside(8'x8' inside) x68" high(wall height not including the roof) with a 32" door, 2"x1"x3/16'' channel frame to hold the 2x8's it will also have a 18"x45*inward pitch(so the coal won't run out)18" off the ground for shovel access with a coal corral in front.I'm not sure on the roof yet but thats not a problem,I need feedback on just setting the block on the concrete without a dug foundation(I will pin the block to the concrete with rebar and pin and fill the each corner)I have two cracks outside the control joints but other then that It looks ok,I will put 8 tons of coal in it plus the weight of the walls which I figure is 9500+16,000=25,500lbs
, so whats everyones opinion on this Idea I have?
My next choice is build a wood bin but I think It will be double in cost and It will sit on the parking area too(but can be moved if needed) but will not weigh as much.I looking forward to hearing what you guys have to say,Thanks. Keepaeyeonit
