Ruin
This tunnel is the largest of the three I visited today. From video 2:03 you may find trenches, the long trenches are still easily recognizable, surrounding the hills, and the entrance of this tunnel is connected to this trench.
At 2:24 I entered the tunnel, it may have a side tunnel on the right side, but it is now too narrow for me. Next to the entrance is a shaft with a pipe hanging in. The most strange thing is a pair of pipes 4:17 penetrating the tunnel. I'm curious about who put them there and what they are used for.
Again, sorry for the camera issues, you may want to rotate your neck left for a comfortable view.

the pipe is for a grounding…
the pipe is for a grounding antenna for a radio system. There is a similar one in the Smugglers Ridge tunnel complex.
