I imagine the mining engineers in the audience will know the solution to this problem, how do you analyze the feasibility of jacking? If you have the earth profile, how do you determine whether the solution is feasible and what is the jacking pressure required?
Okay after further research on the topic, it is possible to jack a box culvert. However, most contractor's prefer a round pipe to a box culvert, because... as the pipes are jacked they have a tendancy to roll. Obviously a square box culvert which rotates is rather a big deal, so extreme care...
For a number of reasons, I would like to replace a number of existing box culverts 8X8 and 10X10 box culverts. I would like to replace them by jacking or other methods instead of open cutting them. Does anyone have experience with this sort of effort?
Thanks
