    Jacking Box Culvert

    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?

    Jacking Box Culvert

    Jacking Box Culvert

    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 Blmsoccer
