I'm doing alot of drafting CADD work while getting my engineering degree. Understanding what is needed is a huge part of making a drawing set. I am lucky enought to be somewhere with a voluminous collection of previous drawings on major civil projects going back over 60 years.
The first thing...
As said before, it's either over, under or through. Burrowing sounds not logistically feasible. I like the idea of the pedestrian island. Perhaps you could have a crossing signal accompanying a 'train crossing' security gate?
My personal favorite though is, build a lightweight pedestrian...
From my experience, non-vertical borings can be a bear at long lengths. Gravity wants to pull the bit down and the hole may deviate. Holes may also become unstable with fall-in material.
My experience has been with core-sampling though at lengths of ~300'. At those distances, it's hard to say...
Thank you guys very much for the feedback. It turns out that the currently stressed shotcrete is very old and has succumbed to freeze/thaw cracks. It doesn't seem like this is very expansive shale. It is currently in a 1:1 slope.
Since water is going to be behind the shotcrete we are going to...
I am designing a shotcrete application for an exposed rock face that is mostly vertical. The rock is currently covered in shotcrete from many years ago. It is currently showing stress cracks pressumably from expanding shale, water pressure, or freeze/thaw cycles.
I am aware of using a geo...
