Nunn CO | Hello all,
We are getting ready to start a new elevator and will be building a drive over pit. On the first round of drafts I sent the engineer I sent him a design with a 1/2 cone as the pit with 40 degree walls. He came back today and said he will make whatever we want, but suggests we seriously consider a rectangular pit. Building square walls is way easier and way more affordable.
The advantages are much cheaper build, easier build, and a rectangle pit has almost 200 bu more volume then a cone.
The disadvantages are potential cleanliness. We need to have the pit self cleaning between lot#'s. If the 3 main angles bottoms are 40 degrees the "corners" will be 30 degrees. That is still steeper then the angle of repo for our grains but it makes me nervous. Every gravity wagon I've ever been around always catches grain where the corners come together.
Our concrete guy suggested instead of making those corners come together with a straight seam (like a gravity wagon) he could make a large rounded radius to avoid trap points.
So, any thoughts or suggestions here? | |
