Abstract
An erosion control device is described. A walled elongated core member is disclosed having a first open end, a second end, an interior space and one or more openings in the wall communicating the interior space with the exterior of the core member. An outer filter member surrounds the core member. One or both the first and second ends of the core member can be open. One or both of the open ends can comprise couplers or connectors for connecting one core member to one or two complimentary core members. The core member may comprise a flexible plastic pipe, such as high-density polyethylene pipe having a plurality of perforations.
Claims25
A soil erosion control apparatus for use above ground, comprising:
- (a) a walled elongated core member having a first open end comprising a coupler, a second end, an interior space and one or more openings in said wall communicating said interior space with the exterior of said core member;
- and
- (b) an outer filter member surrounding said core member and said coupler, wherein said walled elongated core member and said outer filter member both reside above ground.
A soil erosion control apparatus for use above ground, comprising:
- (a) a perforated hollow pipe having a first open end having a coupler attached thereto and a second end;
- and
- (b) an outer filter member surrounding said perforated hollow pipe and said coupler, wherein said outer filter member is formed from one or more materials selected from the group consisting of excelsior, straw and a porous foam material, and wherein said walled elongated core member and said outer filter member both reside above ground.
A soil erosion control apparatus for use above ground, comprising:
- (a) a first walled elongated core member having a first open end having a coupler attached thereto, a second end, an interior space and one or more openings in said wall communicating said interior space with the exterior of said core member;
- (b) a second walled elongated core member having a first open end having a coupler attached thereto and coupled to said coupler of said first walled core member, a second end, an interior space and one or more openings in said wall communicating said interior space with the exterior of said core member;
- and
- (c) an outer filter member surrounding said first core member, said second core member, and one or more of said couplers, wherein said outer filter member is formed from one or more materials selected from the group consisting of excelsior, straw and a porous foam material, wherein said walled elongated core members and said outer filter member all reside above ground.
A soil erosion control apparatus for use above ground, comprising:
- (a) a walled elongated core member having a first open end comprising a coupler, a second end, an interior space and one or more openings in said wall communicating said interior space with the exterior of said core member;
- and
- (b) an outer filter member surrounding said core member and said coupler, wherein said outer filter member comprises a porous foam material, and wherein said walled elongated core member and said outer filter member both reside above ground.
A soil erosion controlling wattle, comprising:
- (a) a walled elongated core member having a first open end comprising a coupler, a second end, an interior space and one or more openings in said wall communicating said interior space with the exterior of said core member;
- and
- (b) an outer filter member surrounding said core member and said coupler, said outer filter member capable of curtailing soil erosion and of passing fluid into said core member.
