Abstract
Abstract A woven coating and protection device which provides for the containment in pockets and for the reinforcement of settable materials such as concrete is disclosed. The coating and protection device may be employed as an erosion control or prevention mat or may alternatively be utilized to provide ballast and protection for underwater pipelines. The device is woven from any desired material with the woven walls of the pockets coming together and being interwoven to form connecting joints between the pockets and further being woven with integral reinforcing guys which strengthen the device and control its shape. The joint areas of material between the pockets may either be permeable or non-permeable as desired to either allow or prevent the flow of water or the growth of vegetation when the device is used in erosion prevention.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
A coating and protection device comprising: a plurality of spaced, generally rectangular containment portions, each said containment portion having spaced first and second walls forming pouches which receive a flowable, settable slurry, said walls being of woven construction; a plurality of flexible joints extending longitudinally and transversely between adjacent containment portions and joining said containment portions to form a flexible mat which is flexible both longitudinally and transversely after receipt and setting of a slurry, said flexible joints being formed by interweaving said first and second walls; a plurality of interconnecting passages in said flexible joints extending between adjacent ones of said pouches, said interconnecting passages being structured to receive injection pipes insertable through a plurality of said pouches and said interconnecting passages to serially feed the slurry to said pouches as said injection pipes are withdrawn through said pouches and said interconnecting passages; a plurality of reinforcing guys, each of said guys having a portion extending between said first and second walls and further having a portion woven integrally with said first and second walls; and reinforcing strands integrally formed with said walls and being disposed generally perpendicularly to said portions of said reinforcing guys woven integrally with said walls.
Claim 2
Dependent Claim
201 words
A coating and protection device comprising: a plurality of spaced, generally rectangular containment portions, each said containment portion having spaced first and second walls forming pouches which receive a flowable, settable slurry, said walls being of woven construction; a plurality of flexible joints extending longitudinally and transversely between adjacent containment portions and joining said containment portions to form a flexible mat which is flexible both longitudinally and transversely after receipt and setting of a slurry, said flexible joints being formed by interweaving said first and second walls; a plurality of interconnecting passages in said flexible joints extending between adjacent ones of said pouches, said interconnecting passages being structured to receive injection pipes insertable through a plurality of said pouches and said interconnecting passages to serially feed the slurry to said pouches as said injection pipes are withdrawn through said pouches and said interconnecting passages; a plurality of reinforcing guys, each of said guys having a portion extending between said first and second walls and further having a portion woven integrally with said first and second walls; and reinforcing strands integrally formed with said walls and being disposed generally perpendicularly to said portions of said reinforcing guys woven integrally with said walls.
Claim 3
Dependent Claim
42 words
The coating and protection device of claim 1 wherein said flowable slurry is a cement which hardens within said pouches, said slurry hardening about said portions of said guys extending between said walls whereby said guys retain said hardened slurry in place.
Claim 4
Dependent Claim
26 words
The coating and protection device of claim 2 wherein said device is a fabric mat which, when filled with said slurry, forms an erosion control means.
Claim 5
Dependent Claim
25 words
The device of claim 3 wherein said joints are impermeable to liquid whereby said erosion control device will not allow the passage of liquid therethrough.
Claim 6
Dependent Claim
25 words
The device of claim 3 wherein said joints are permeable to liquid whereby said erosion control device will allow passage of liquid through said joints.
Claim 7
Dependent Claim
37 words
The coating and protection device of claim 2 wherein said device is secured about an elongated cylindrical object and which, when filled with said slurry forms a protective coating and ballast means for said elongated cylindrical object.
Claim 8
Dependent Claim
24 words
The coating and protection device of claim 1 further wherein said reinforcing strands intersect said reinforcing guys where said guys pass through said walls.
