Abstract
An erosion protection device is provided to control erosion in environments prone to water induced erosion. Each individual device includes a central core area, and six generally equally sized legs projecting outward from the core at equal spacing in each direction. Spacers are provided at the interface of the legs and core. Multiple devices are group together to form a protective nested group to form a protective cover.
Claims10
An interchangeable member for placement into a grid for protection of a water land interface, comprising:
- a central core;
- a plurality of legs radiating outward from said core, the intersection of said legs at said core forming an interstice;
- a spacing means for spacing the member adjacent other members in the grid disposed at at least one interstice and being formed of a raised portion of said legs at said interstice.
An erosion barrier, comprising:
- at least two nestable members, each of said members including a central core portion and a plurality of legs radiating outward therefrom;
- at least one of said members receiving a filter membrane thereon, and one of said legs of next said member received on said filter membrane on said one member.
An interchangeable member for nesting with similar members, comprising:
- a first and a second member portion;
- each of said member portions including an erosion control profile including a central core and at least two radiating legs radiating from and intersecting at said core;
- said cores further including complementary mating profiles for interconnection of said profiles;
- and,
- a projection disposed at the intersection of said legs forming a spacing member to space the interchangeable member with respect to adjacently nested interchangeable member by abutting the adjacent member.
