I would hope that not all of this is buried to deep.   The first thing to do when pulling is mark your wire and keep track of how many feet you have pulled. That way if you need to dig it up you at least know where the end is. I would also try to plan a few dig places. (bends etc.) where you can cut a piece of the conduit out. Pull all the wire to that splice then feed it through the cutout and the rest of it.   unless you find something different than usual you better figure on trouble. Make sure you have some chinese handcuffs on each wire and stagger the ends.

    good luck let us know how you make out.
