There are a number of ways to build a tunnel. The location of the structure and the material through which the tunnel will pass will dictate the approach used. Sometimes we just blast away rock, like in the side of a mountain. Other times will use a boring machine to cut through materials, and we'll install "pieces" behind the machine that become the sides and overhead of the tunnel. We might dig a big "trench" in the ground, put in supports and an overhead, and then cover the whole thing over. Other tunnels are built in sections, like "tubes" or something similar, and are then placed under water, linked together and sealed, and then pumped out to form the tunnel. There are yet other techniques, and you can begin to learn about them by using the link below.

What is water pressure tunnel?
Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.

If five men can dig five tunnels in five days then how many tunnels can one man dig in one day?
If five men can dig five tunnels in five days, that means each man is digging one tunnel in five days. So, one man can dig one tunnel in five days. In one day, a man can dig one-fifth of a tunnel. So, in one day, one man can dig 0.2 tunnels. Hope that clears things up for you!
