tunnel filling
tunnel filling
(OP)
We have a 36 feet diameter tunnel supplying water to four turbines.The rated head of the units is 384 feet.Now from where the penstock of the units start the tunnel diameter has been increased.Thus we have four areas where tunnel diameter is more.On top of these four areas are air release lines used for aior release while filling the tunnel.
Now one of the air release pipes,embedded in ten feet concrete has cracked and leaks when tunnel is full.Can we plug this line.What will happen to the air at top of this area

RE: tunnel filling
Or you could line the pipe.
The technology for inserting a plastic liner into, e.g. a municipal water pipe and then expanding it, and opening any branch connections, must be pretty mature by now.

OR, You could plug the line, and depending on the setup, the other air release pipes may be able to compensate for the blocked one. (If I understand your setup corectly, and they are all releasing air out of the same resevoir).
