How can we design a shoring system for a ductbank(0.8m x 0.8m) 2 meters below the rail tracks, with limitations of no steel shoring or trench boxes? We will be using wooden shoring, ensuring the rail remains in place.
How to support rails, potentially using lumber and jacking from the bottom? Any suggestions.
