Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A jetty arranged angularly in relation to the edge of a body of water, to slow down and/or detour currents, comprising a. a non-woven porous web of randomly arranged continuous filaments lining an excavation and having edges extended beyond the excavation, b. a pile of fill in said excavation and extending upwardly therefrom to form a surface outside of the excavation, c. said extended edges of said non-woven web being wrapped back against the outside surface of the pile to surround said pile of fill, and d. a layer of wave-breaking elements superimposed on said wrapped edges of the non-woven web.
Claim 2
Dependent Claim
101 words
A jetty arranged angularly in relation to the edge of a body of water, to slow down and/or detour currents, comprising a. a non-woven porous web of randomly arranged continuous filaments lining an excavation and having edges extended beyond the excavation, b. a pile of fill in said excavation and extending upwardly therefrom to form a surface outside of the excavation, c. said extended edges of said non-woven web being wrapped back against the outside surface of the pile to surround said pile of fill, and d. a layer of wave-breaking elements superimposed on said wrapped edges of the non-woven web.
Claim 3
Dependent Claim
20 words
The jetty according to claim 1, wherein the edges and top of said pile are reinforced with a chemical binder.
Claim 4
Dependent Claim
19 words
The jetty according to claim 1, wherein said layer of continuous filaments weighs between 300 and 1200 g/square meter.
