I think it was mentioned earlier in the show that ballista were pretty much not invented, because the one shown to Cersei was the first of its kind, and that tech stayed with her army even though Jaime fled. Considering the amount of time they had to reinforce being very little, it would be a small stretch to say they had enough time to reverse engineer and reconstruct the one they saw hurt Drogon only a week before. Not to mention, Drogon immediately destroyed that ballista and it's the first and only time they would have seen it, so they've got nothing to work with.
