Meaning of 'wound up going through'

[Liqichao]

hello everyone,
here is the sentence: it wound up going through what is now a large pothole in the runway.

what does the 'wound up going through' mean? and how can I use it?

thank you for your answers :D

Hi,

I would say: It ended up going through a large pothole = that's where it finally stopped.

It describes a causal conclusion.

I see, thank you.
but I am still confused because I don't know how to cut the sentence for reading. and confused about the words like wound up, going through, what is now. anyway, I just cannot make sense about these three part and why they are used in such way.
why not go through but going through.

thank you for your explaination.
