Abstract
Disclosed is a flood barrier which, in one embodiment, comprises a resiliently deformable barrier mounted removably via frame members on post footing. At least some embodiments of the barrier may be more rapidly and easily deployable and may be considerably lighter and cheaper to manufacture and yet provide surprising durability and resistance to water flows compared to conventional barrier constructions.
Claims17
An environmental protection barrier for providing protection from a moving body of water, said barrier comprising a resiliently deformable barrier portion mounted on substantially rigid frame members adapted to be located between a plurality of substantially rigid upwardly extending posts, so as to secure said barrier portion in the path of said body of water, said posts being removably deployable onto post footings extending at least 50 cm below ground level;
- wherein said resiliently deformable barrier portion has a thickness of between 5 and 50 mm and a mass per unit area of between 5 and 20 kg per square metre, and wherein said barrier portion is adapted to deform or move reversibly from an initial configuration to absorb or deflect energy from said moving body of water.
An environmental protection barrier for providing protection from a moving body of water, said barrier comprising a resiliently deformable barrier portion secured in the path of said body of water by a plurality of substantially rigid upwardly extending posts, wherein said resiliently deformable barrier portion has a thickness of at least 5 mm and a mass per unit area of at least 5 kg per square metre, and wherein said barrier portion is adapted to deform or move reversibly from an initial configuration to absorb or deflect energy from said moving body of water.
A method for erecting a deployable flood barrier comprising the steps of:
- securing a plurality of posts to a corresponding plurality of post footings;
- attaching a plurality of frame members to said posts;
- and
- attaching a substantially impermeable, resiliently deformable layer to said frame members, said resiliently deformable layer having a thickness of between 5 and 50 mm and a mass per unit area of between 5 and 20 kg per square metre
