DATA:Consider 100 mm dia GI pipe for air line and 80 mm dia GI pipe for water line.

For 1 km tunnel consider 1250 m length air line including pipe line from air compressor shed

to tunnel / adit portal.

For 1 km tunnel consider 1500 m length water line including pipe line from pumping point to

starage water tank and from storage water tank to tunnel / adit portal.

Air and water lines are extended inside the tunnel as the excavation progresses and are

dismantled progressively during concreting. Considering 24 months as the construction period

for 1 km tunnel the weighted average use of air and water lines will be for 18 months.
