In the future get to know your neighbors if you can. Neighbors who are friendly are much less likely to raid you and are likely able to help you in situations like this.
Otherwise, it doesn't matter if you have base 10 strength or not, just spawn alts onto your hearthfire and run multiple clients to have them all online at the same time.
A palisade wall segment has 25 soak. Battering Rams add 20 damage, so all that you need to do to break the soak is 6 more damage. You can have up to 4 characters add their damage to a ram at the same time. At 10 strength you add 3 damage, 26 would add 5 damage. Your main character + 1 alt will add up to more than 6 damage. If you wanted to, you could break out. =)
If you could get your strength to 36 then you could do it on your own. Wine, boar snuff, and anything else that adds strength can help. Even if the duration on the buff ends, if you are already ramming a segment then you act as if you still had the buff until you stop.
