Abstract

A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles includes a composite bed system having a plurality of elevations and comprising a first layer beneath a second layer. The first layer includes a deformable material configured to collapse when subjected to vehicle loads, and the second layer includes a pedestrian cover surface over the deformable material that conceals the deformable material. The pedestrian cover surface is configured to support pedestrian traffic over the deformable material without permanently collapsing the deformable material and to collapse along with the first layer when subjected to vehicle loads. A structure beyond the bed system is provided to resist the impact of a vehicle that has traversed the bed system.

Claims

1. A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles comprising:

a composite bed system having a plurality of elevations and comprising a first layer beneath a second layer, the first layer comprising a deformable material configured to collapse when subjected to vehicle loads, the second layer comprising a pedestrian cover surface over the deformable material that conceals the deformable material, the pedestrian cover surface configured to support pedestrian traffic over the deformable material without permanently collapsing the deformable material and to collapse along with the first layer when subjected to vehicle loads; and

a structure beyond the bed system configured to resist the impact of a vehicle that has traversed the bed system.

2. The system of claim 1 wherein the plurality of elevations increase in height relative to the trafficable surface as the vehicle travels from the trafficable surface toward the structure.

3. The system of claim 2 wherein the plurality of elevations increase in height by a substantially constant increment.

4. The system of claim 3 wherein the increment is within a range of approximately three (3) inches to twelve (12) inches.

5. The system of claim 4 wherein the plurality of elevations are configured in a stepped arrangement.

6. The system of claim 1 wherein the deformable material is one of a cellular concrete, resin, polymeric foam, metallic foam, synthetic foam or a composite material.

7. The system of claim 6 wherein the deformable material has a compressive strength configured to crush, break, or tear under the weight of a tire of a vehicle that is loaded to at least approximately 2,500 lbs.

8. The system of claim 1 wherein the pedestrian cover surface is a paving system comprising at least one of bricks, cobble stones, stone pavers, and concrete pavers.

9. The system of claim 1 wherein the structure beyond the bed system comprises a retaining wall.

10. The system of claim 9 wherein the retaining wall comprises a front wall, a rear wall and at least one side wall.

11. The system of claim 10 wherein the walls comprise at least one of reinforced concrete, masonry, wood, sheet metal, mesh, fabric, compacted soil, and a composite material.

12. The system of claim 10 further comprising a floor structure below the bed.

13. The system of claim 10 wherein a top of the rear wall and one of the plurality of elevations have a substantially common elevation.

14. A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles comprising:

a composite bed system comprising a first layer beneath a second layer, the first layer comprising a deformable material configured to collapse when subjected to vehicle loads, the second layer comprising a pedestrian cover surface over the deformable material and having a plurality of elevations that conceal the deformable material, the pedestrian cover surface configured to support pedestrian traffic over the deformable material without permanently collapsing the deformable material and to collapse along with the first layer when subjected to vehicle loads; and

a structure adjacent to the bed system configured to resist the impact of a vehicle that has traversed the bed system.

15. The system of claim 14 wherein the plurality of elevations progressively increase in height in a direction from the trafficable surface toward the structure.

16. The system of claim 15 wherein the plurality of elevations are configured in a stepped arrangement at height increments within a range of approximately three (3) inches to twelve (12) inches.

17. The system of claim 14 wherein the deformable material is one of a cellular concrete, resin, polymeric foam, metallic foam, synthetic foam, and a composite material.

18. The system of claim 14 wherein the deformable material has a compressive strength configured to crush, break, or tear under the weight of a tire of a vehicle that is loaded to at least approximately 2,500 lbs.

19. The system of claim 14 wherein the pedestrian cover surface comprises at least one of bricks, cobble stones, stone pavers, and concrete pavers.

20. The system of claim 14 wherein the structure adjacent to the bed system is a retaining wall.

21. The system of claim 20 wherein the retaining wall comprises a front wall, a rear wall and at least one side wall.

22. The system of claim 21 wherein the walls comprise at least one of reinforced concrete, masonry, wood, sheet metal, mesh, fabric, compacted soil, and a composite material.

23. The system of claim 21 further comprising a floor structure below the bed system.

24. The system of claim 21 wherein a top of the rear wall and one of the plurality of elevations have a substantially common elevation.

25. A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles comprising:

a deformable zone having a plurality of elevations above the trafficable surface and at least two distinct structures of differing materials, the first structure comprising a deformable material configured to collapse when subjected to vehicle loads, the second structure comprising a pedestrian cover surface over the first structure that conceals the first structure, the second structure configured to support pedestrian traffic over the first structure without permanently collapsing the first structure and to collapse along with the first structure when subjected to vehicle loads; and

a structure adjacent to the deformable zone configured to resist the impact of a vehicle that has traversed the deformable zone.

26. The system of claim 25 wherein a height of the plurality of elevations progressively increase in a direction from the trafficable surface toward the structure.

27. The system of claim 26 wherein the plurality of elevations are configured in a stepped arrangement at height increments within a range of approximately three (3) inches to twelve (12) inches.

28. The system of claim 25 wherein the trafficable surface has a plurality of elevations.
