Abstract
A modular dike or barrier assembly includes straight and curved members that may be interconnected to form a barrier or dike wall surrounding a primary container. The members are hollow and include opposed side walls having integrally formed reinforcing ribs. The side walls extend at an acute angle relative to the base of the barrier to contain and redirect a surge flow directed toward the dike or barrier assembly. The interior surfaces of the side walls are closely spaced at locations spaced from the ribs and tend to abut for added wall reinforcement upon application of wall deflecting loads.
Claims15
A liquid surge resistant modular barrier comprising:
- a plurality of members extending in a longitudinal direction to longitudinal ends that are connected to form said barrier,
- each member including a top portion connected to a central wall portion having first and second opposed side walls that extend to a base portion having a base wall for engagement with a support surface, and
- at least one of said side walls extending at an acute angle relative to the base wall toward the liquid to be contained to tend to redirect a liquid flow toward the member, wherein said members include straight and curved members, each of said members is a hollow closed element formed of a continuous layer of plastic, said members include elongate reinforcing ribs in said side walls, said reinforcing ribs extend in first and second directions that are angularly offset, said reinforcing ribs extend in said first direction in said first side wall and extend in said second direction in said second side wall, and said first and second side walls have adjacent interior wall surfaces at locations between opposed reinforcing ribs that engage upon deflection of said side walls in said first or second direction to reinforce said side walls and said member.
A liquid surge resistant modular barrier comprising;
- a plurality of members extending in a longitudinal direction to longitudinal ends that are connected to form said barrier,
- each member including a top portion connected to a central wall portion having first and second opposed side walls that extend to a base portion having a base wall for engagement with a support surface, and
- each of said first and second side walls extending in an acute angle relative to said base wall toward the liquid to be contained, each of said side walls including reinforcing ribs, said reinforcing ribs extending in said side walls in a horizontal direction in one side wall and a vertical direction in the other side wall to resist buckling or flexure of said member in a vertical or horizontal direction.
A liquid surge resistant modular barrier comprising;
- a plurality of members extending in a longitudinal direction to longitudinal ends that are connected to form said barrier,
- each member including a top portion connected to a central wall portion having first and second opposed side walls that extend to a base portion having a base wall for engagement with a support surface, and
- each of said first and second side walls extending in an acute angle relative to said base wall toward the liquid to be contained, each of said side walls including reinforcing ribs, said reinforcing ribs extending in said side walls in rib directions that are angularly offset to resist buckling or flexure of said member in a vertical or horizontal direction, wherein said first and second side walls have adjacent interior wall surfaces at locations between opposed reinforcing ribs that engage upon flexure of said side walls to reinforce said member.
A liquid surge resistant modular barrier comprising:
- a plurality of members extending in a longitudinal direction to longitudinal ends that are connected to form said barrier with a closed configuration surrounding liquid to be contained,
- each member including a top portion connected to a central wall portion having first and second opposed side walls that extend to a base portion having a base wall for engagement with a support surface, and
- each of said first and second side walls extending in an acute angle relative to said base wall toward the liquid to be contained, each of said side walls including reinforcing ribs, said reinforcing ribs extending in said side walls in rib directions that are angularly offset to resist buckling or flexure of said member in a vertical or horizontal direction, wherein said base portion has a substantially triangular cross-sectional shape including an inclined base wall extending upwardly from said base wall to join one of said side walls, said inclined base wall extending to said one of said side walls at an angle of up to about 60° relative to said base wall, and said first and second side walls have adjacent interior wall surfaces at locations between opposed reinforcing ribs that engage upon flexure of said side walls to reinforce said member.
