Claim 18:
19. An underground shelter comprising:
a housing unit having at least six panels, wherein one of the panels is a base panel connected to a bottom of the housing unit, wherein the at least six panels are affixed to each other along an interface, and wherein the at least six panels encompass an interior of the housing unit;
at least one entry port into the housing unit, wherein the at least one entry port allows access into an interior of the housing unit, wherein the at least one entry port is at least partially covered by a removable entry hatch;
a framework attached to the housing unit comprising at least two beam supports, wherein each beam support traverses across a corresponding one of the at least six panels, and wherein two of the at least two beam supports interface with each other and are perpendicular to each other;
at least one of the two beam supports having a notch at an area where the two of the at least two support beams interface and each of the at least six panels interface with each other, wherein the notch allows for a straight weld line along the interface between the at least six panels;
the housing unit having at least one connect point, wherein the at least one connect point allows for the housing unit to be connected to at least one cable to facilitate moving the entire housing unit;
the housing unit having a floor, wherein the floor is located above the base panel in the interior of the housing unit, wherein the floor is supported by one or more joists;
the floor having at least one storage hatch, wherein the at least one storage hatch opens to allow for access to a storage space in between the floor and the base panel;
an air intake system comprising:
at least one air intake pipe connected to a corresponding sloped intake air pipe connected to a corresponding vertical intake pipe, wherein the vertical intake pipe is attached to an exterior of an underground shelter, and wherein the sloped intake air pipe is angled downward away from the point at which the corresponding vertical intake pipe is connected to the corresponding sloped intake pipe, wherein the sloped intake pipe is configured such that condensation that forms in the sloped intake pipe drains away from the corresponding vertical intake pipe and into the corresponding air intake pipe, and wherein the air intake pipe is configured such that air located above ground, outside of the underground shelter, traverses through the at least one air intake pipe, through a corresponding vertical sloped intake air pipe, and through a corresponding vertical intake pipe to enter the interior of the underground shelter;
at least one vertical exhaust pipe connected to a corresponding surface exhaust pipe, wherein the at least one vertical exhaust pipe is attached to an exterior of the underground shelter, and wherein the at least one vertical exhaust pipe is configured such that air located in the interior of the underground shelter traverses through the at least one vertical exhaust pipe and through the corresponding surface exhaust pipe to egress out of the interior of the underground shelter;
the at least one surface intake pipe, the at least one vertical intake pipe, and the at least one vertical exhaust pipe each have a corresponding lower disposal pipe segment, wherein the corresponding lower disposal pipe segments protrude downward toward a distal end of the corresponding pipes; and
each lower disposal pipe segment having at least one check valve, wherein the at least one check valve is connected to the corresponding lower disposal pipe at a distal end of the corresponding lower dispoal pipe, wherein the at least one check value is configured to allow received condensation to egress out of the corresponding lower disposal pipe segments, while air is inhibited from entering through the at least one check valve.
