Question

how to build under ground bunkers?

Answer 1

A buried or semi-buried shelter outdoors would offer worthwhile protection for your family. The English built these by the thousands during the Battle of Britain. World War II brought them to many parts of Europe. Danger of tornados has already brought similar storm cellars to many parts of the American mid-West.



Ideally, your shelter should be completely underground, braced by foot-thick reinforced concrete walls and ceiling, with forced-draft ventilation piped through special filters which can eliminate radioactive dust or water droplets. But simple semi-buried earth-and-pole shelters, caves or tunnels dug into hillsides can give protection against blast, heat and radiation very close to ground zero. Outdoor blast bomb shelters of the type used in World War II, if covered with at least 20 inches of packed soil, would reduce nuclear radiation below the death level at distances greater than 3,000 feet from the explosion. The same effect would be achieved by roughly 12 inches of concrete, four inches of iron or about two inches of solid lead.

I've thought about this,I thought of using rail road cars, maybe sitting them side by side and connect them together with large culvert pipe, then coating everything, with a heavy coat of tar. The only problem you have with underground, is water, if it's on side of a hill ,you can place French drain around it, to divert the water,. But my solution was to place them on top of the ground, with good drainage,, and place dirt on sides and top. another option is to have a precast or fiberglass storm shelter placed under ground, alot of contractors do this. I'm sure if you typed in storm shelter, you would get something on line. I located a very nice site for do-it-yourself shelters. Go to Domestic Nuclear Shelters, has drawings and everything you need. Good Luck
