Method and apparatus for containing and suppressing explosive detonations

A transportable explosion chamber, comprising:

• an elongated cylindrical blast-resistant metal inner vessel, said inner vessel having at one end an access door opening and an inward-opening blast-shielded access door, and at an opposite end a vent opening and an inward-opening blast-shielded vent door,
• a plurality of fabricated support ribs surrounding said inner vessel, and
• a plurality of metal outer skin panels surrounding and enclosing said support ribs, thereby forming an elongated double-wall chamber assembly having a top, a bottom, and a plurality of hollow spaces formed between said inner vessel, support ribs and metal outer skin panels, wherein said inward-opening blast-shielded access door comprises a door plate substantially overlapping said door opening, and shield plates forming a truncated pyramid shape extending inwardly into the inner vessel to dissipate shock waves from explosive detonations.

A transportable explosion chamber, comprising:

• an elongated cylindrical blast-resistant metal inner vessel, said inner vessel having at one end an access door opening and an inward-opening blast-shielded access door, and at an opposite end a vent opening and an inward-opening blast-shielded vent door,
• a plurality of fabricated support ribs surrounding said inner vessel, each comprising a plurality of individual interlocking components, and each said support rib rib having at its periphery outwardly-facing attachment tabs, and
• a plurality of metal outer skin panels surrounding and enclosing said support ribs, thereby forming an elongated double-wall chamber assembly having a top, a bottom, and a plurality of hollow spaces formed between said inner vessel, support ribs and metal outer skin panels.

A transportable explosion chamber, comprising:

• an elongated cylindrical blast-resistant metal inner vessel, said inner vessel having at one end an access door opening and a blast-shielded access door, and at an opposite end a vent opening and a blast-shielded vent door,
• a plurality of fabricated support ribs surrounding said inner vessel, and
• a plurality of metal outer skin panels surrounding and enclosing said support ribs, thereby forming an external enclosure, wherein each said support rib has a substantially circular inner perimeter and/or a substantially octagonal outer perimeter.
