I Thought they used I beams for shoring, interesting.
There's many different kinds! I think they are building a retaining wall at the back between this lot and the building behind.I Thought they used I beams for shoring, interesting.
Has to do with RQD testing if it sits in certain range they used different sizes/ dimensions. (rock quality designation). Might also have to do with principal stress direction but I’m not too sure about that. Anyways that’s what they do in mining.There's many different kinds!
