Abstract
Abstract A bottom and bank facing for preventing erosion of subaqueous soil structures comprising a lattice of fascines fastened to a mat of synthetic resin material, wherein the resin material comprises a fabric sheet having means attached thereto for use in securing the fascines to the fabric, such means including transversely spaced groups of threads, each group being woven into the fabric at spaced portions along their length to provide resultant loops or floating portions in each group of threads to which the fascines are attached; or separate strips of fabric fastened to the fabric sheet for being tied to the fascines.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
221 words
A bottom and bank facing for preventing erosion of subaqueous soil structures on which it is placed comprising a strong, slightly elastic, sandtight, water permeable continuous mat of synthetic resin fabric lying on the soil surface to be protected, a lattice of fascines superposed on said mat and comprising a set of spaced parallel lower fascines disposed on said mat and a set of spaced parallel upper fascines overlying said lower fascines and crossing said lower fascines substantially at right angles, said mat having on its upper surface at each crossing of said upper and lower lattices and intermediate said crossings receiving means connected with said mat and providing openings to receive tying material, and strands of tying material passing over said fascines and through respective openings of said receiving means at each said crossing and intermediate said crossings to secure the crossing fascines to one another and to secure said fascines in said mat, said strands of tying material passing through said openings of said receiving means without passing to the lower side of said mat and thereby avoiding discontinuities in the fabric of said mat, said fascines being disposed solely on the upper face of said mat whereby said mat lies on the surface of the soil to be protected without fascines therebetween, thereby avoiding undermining of the facing.

A bottom and bank facing for preventing erosion of subaqueous soil structures on which it is placed comprising a strong, slightly elastic, sandtight, water permeable continuous mat of synthetic resin fabric lying on the soil surface to be protected, a lattice of fascines superposed on said mat and comprising a set of spaced parallel lower fascines disposed on said mat and a set of spaced parallel upper fascines overlying said lower fascines and crossing said lower fascines substantially at right angles, said mat having on its upper surface at each crossing of said upper and lower lattices and intermediate said crossings receiving means connected with said mat and providing openings to receive tying material, and strands of tying material passing over said fascines and through respective openings of said receiving means at each said crossing and intermediate said crossings to secure the crossing fascines to one another and to secure said fascines in said mat, said strands of tying material passing through said openings of said receiving means without passing to the lower side of said mat and thereby avoiding discontinuities in the fabric of said mat, said fascines being disposed solely on the upper face of said mat whereby said mat lies on the surface of the soil to be protected without fascines therebetween, thereby avoiding undermining of the facing.
Claim 3
Dependent Claim
29 words
A facing according to claim 1, wherein the synthetic resin material fabric is a fabric of polyethylene yarn, said fabric having a tensile strength of at least 2,000 kg/m.
Claim 4
Dependent Claim
100 words
A facing as set forth in claim 1, in which said receiving means comprises a plurality of elongated spaced groups of threads disposed in parallel and woven into said synthetic resin fabric only at transversely aligned intermittent portions along the extent of said threads, thereby providing floating portions of said threads between said intermittent portions, one of said sets of fascines being disposed in alignment with said groups of parallel threads, and in which said strands of tying material for securing said fascines to said mat pass under said floating portion of said groups of threads and over said fascines.
Claim 5
Dependent Claim
32 words
A facing according to claim 3, in which said groups of threads are of a first color, and said fabric is otherwise of a second color which contrasts with said first color.
Claim 6
Dependent Claim
87 words
A facing as set forth in claim 1, in which said receiving means comprises a plurality of separate strip means of synthetic resin fabric attached to said mat for enclosing at least a portion of the circumference of said lower fascines along a substantial longitudinal extent thereof, and for enclosing spaced portions of said upper fascines, and means for securing said strip means to said mat, said strip means having eyelets therein to receive said strands of tying material passing through said eyelets and over said fascines.
Claim 7
Dependent Claim
15 words
A facing according to claim 5, wherein the strip means are sewn to the mat.
Claim 8
Dependent Claim
26 words
A facing as set forth in claim 1, in which the spacing between said parallel fascines is of the orDer of three quarters to 1 meter.
Claim 9
Dependent Claim
59 words
A facing as set forth in claim 1, in which said mat extends beyond at least one of the two outermost fascines in one of said sets of fascines and is folded back to form a flap, and further comprising means attaching the edge of said flap to said mat to provide pocket means for holding a ballast weight.
Claim 10
Dependent Claim
51 words
A facing as set forth in claim 1, in which said lower fascines are disposed longitudinally in a common plane below said upper fascines, and in which said mat is disposed in continuous contact with said lower fascines along the entire longitudinal coincident extent of said mat and said lower fascines.
Claim 11
Dependent Claim
110 words
A facing as set forth in claim 9, in which the synthetic resin fabric is a fabric comprising polyethylene yarn, said fabric having a tensile strength of at least 2,000 kg/m'', and further comprising a plurality of elongated spaced groups of threads disposed in parallel and woven into said fabric only at transversely aligned intermittent portions along the extent of said threads, the fascines of one of said sets of fascines being disposed in alignment with said respective groups of threads, and in which said strands of tying material for securing said fascines to said mat pass under said floating portion of said group of threads and over said fascines.
Claim 12
Dependent Claim
37 words
A facing as set forth in claim 10, in which said polyethylene yarn is disposed in the warp in said fabric, said fabric further comprising weft yarn selected from the group consisting of polyamide polyester or polypropylene.
