That is such a hard picture to view. I hope he gets through the night and you are a wonderful person for doing all you can. Maybe it was best that he didn't drink or eat in the predicament that he's in. My thoughts and prayers for this guy and your efforts.
Edit: I just thought Of something that might help when you go back in the morning: bring some oil, anything that you can saturate around the hole and or his neck if he isn't struggling. The vibration of working the concrete along with the oil may be just enough for his head to slip back in if there is a solid floor under him and not in danger of falling further down in a tunnel.
