Abstract
A blast protection structure is formed of one or more bags, generally shown as (1) in FIG. 2. Such bags comprise an upper and lower compartment, with the lower compartment having a reinforcing layer (2), preferably formed of an impact reactant structure such as Kevlar®. The upper surface (3) of the upper compartment, has a non-slip coating to provide improved stacking of bags. Such bags can be used to provide blast protection structures to minimize the risk of damage from an explosion.
Claims16
A ground supportable blast protection structure, comprising:
- a plurality of rupturable inflatable containers defining when inflated a blast protection wall having substantially parallel opposing side wall surfaces,
- at least one filler aperture and a corresponding closure means permitting the containers to be filled with a liquid,
- wherein the opposing side wall surfaces of each of said plurality of containers are interconnected by a drop stitch material, said drop stitch material prevents or inhibits outward bulging of the side wall surfaces when the containers are filled with the liquid to thereafter retain the opposing sidewall surfaces substantially parallel to each other.
A ground supportable blast protection structure, comprising:
- a plurality of inflatable containers defining when inflated a blast protection wall,
- each of said containers having an aperture opening to an inflatable core thereof and a removably replaceable cap for sealably closing said aperture, said aperture being adapted to receive a flowable substance that inflates said core, and
- each of said containers having tongues and grooves that interlock with grooves and tongues of adjacent ones of said containers.
