Description

SYNTHETIC ANCHORED REVETMENT AND METHOD Technical Field

[0001] The present invention relates to load-bearing revetment structures that overlie ground surfaces of land sites for supporting loads and resisting physical impacts from vehicles, maintenance equipment, debris and / or hydraulic flows. More particularly, the present invention relates to load-bearing revetment structures that anchor to ground covers overlying ground surfaces of land sites with structural and compressive strength for high traffic loading and impact applications of supporting vehicles and maintenance equipment roadways or storage pads, water and hydraulic applications, pipeline crossings and land stabilization, and to methods of installing load-bearing revetments structures on ground surfaces of land sites. Background of the Invention

[0002] Large area sloped land sites such as landfills, levees, dams, and flood channels are traversed by vehicles for personnel to travel for land site use, inspection, and maintenance such as work crews cutting weeds. Many large area land sites are covered with tufted geotextiles to provide an ornamental covering while with an impermeable back restricting ambient water inflow into the land site. Light duty motor vehicles may pass over generally without damage to the installed tufted geotextile. However, sloped surfaces common in landfill sites may have swales and dished ridges or ravines. Motor vehicle travel over such elevation changes may cause damage.

[0003] Revetment structures placed along water flow channels such as streams and riverbanks to stabilize or protect the bank from erosion. Revetments are usually constructed with rock, but other materials have been used with success including concrete, concrete-mat, concrete blocks, 4890-3995-7486v1 2171320-00016510 / 10 / 2024gabions, and a host of other materials. These types of revetments however are unsatisfactory for landfills, levees, dams, and flood channels overlaid with a tufted geotextile as a ground cover.

[0004] Accordingly, there is a need in the art for a robust structural and compressive strength revetment system for heavy load and impact-resistant land site industrial applications using tufted geotextiles for covering a ground surface. It is to such that the present invention is directed. Brief Summary of the Invention

[0030] With reference to the drawings, in which like parts have like identifiers, Fig.1 illustrates in perspective view an embodiment of an anchored load-bearing revetment structure 10 in accordance with the present invention on a land site 12. The land site may have a substantially horizontal surface or a sloping surface with ordinary ground surface variations as well as slopes, swales, ditches, culverts, benches, and other land site features.

[0031] The anchored load-bearing revetment structure 10 comprises a tufted geotextile 14 overlying a ground surface of the land site 12 as a ground cover. The tufted geotextile 14 has an elongated backing sheet 16 or web tufted with a plurality of yarns to define a plurality of spaced- apart tufts 18 extending as simulated blades of grass. The backing sheet 16 of the tufted geotextile may be a woven sheet or a non-woven web. The bottom surface of the elongated backing sheet 4890-3995-7486v1 2171320-00016510 / 10 / 202416 of the tufted geotextile 14 may be sealed with a polymeric coating. The coating may providegeotextile has reduced permeability for moderating water flow downwardly through the tufted geotextile into the ground. In an alternate embodiment, the ground surface is overlaid by an elongated geomembrane sheet that is typically impermeable to prevent seepage of ambient environmental water such as from rain or snow melt into the ground below.

[0032] With reference also to the detailed view in Fig.4, a formwork 20, or “a confining mat”, seats on a portion of the tufted geotextile 14. The formwork 20 is a three-dimensional elongated geometric arrangement or structure having a plurality of spaced-apart open vessels 22 or receiving passages defined by walls and interconnected in spaced-relation, as shown in the illustrated embodiment by span members 24, as a confining mat. The spaced vessels 22 define a pattern that is regular or irregular. The formwork 20 comprises the confining mat with multiple open (bottom and top) receiving passages defined by walls of the vessels 22 as a three-dimensional elongate form that is laid atop the tufted geotextile 14. The open bottom permits respective ones of the tufts 18 to enter into the receiving passages or vessels 22. The open top permits filling the receiving passages or vessels 22 with the infill 30 to secure to the tufts and to interconnect the tufted geotextile 14 to the formwork confining mat. The infill 30 cures or solidifies. The infill 30 thereby fixes to the tufts to secure and interconnect the tufted geotextile 14 and formwork 20 as the load- bearing revetment structure 10. The formwork 20 may be made of various materials, such as plastic, metal, polyethylene, paper, cardboard, fabric, wood, or other shape-holding material. In an alternate embodiment, the formwork 20 includes geocell sheets, geowebs, or other cavity or vessel defining confining members. The formwork 20 comprises a geometric structure that has infill receiving cavities or vessels held in spaced-relation (ordered or irregularly arranged) for 4890-3995-7486v1 2171320-00016510 / 10 / 2024confining infill in place during installation and use. The formwork thereby restricts lateral displacement of confined infill engaged to tufts upon loading on the anchored load-bearing revetment structure 10 by, for example, vehicle traffic or water flow.

[0033] With reference to Fig.2 illustrating a cross-section on line 2 - 2 in Fig.1 of the land site 12 and the anchored load-bearing revetment structure 10, respective ones of the plurality of tufts 18 extend into respective ones of the open vessels 22. The tufts 18 extend upwardly within the open vessels 22, as shown in broken-away view at 25. The height of the formwork 20 preferably exceeds a distal extent of the tufts 18. The tufts 18 extend to a distal extent for being received within the vessels 22 but preferably not extend beyond the height of the formwork. The formwork 20 receives the infill 30 as illustrated in perspective view in Fig. 5. The infill 30 fills onto the tufted geotextile 14 and into the vessels 22 around the extending tufts 18, to the upper extent of the formwork. Some of the infill 30 may fill above the height of the formwork 20. The infill 30 hardens as discussed below and encases the tufts 18. The tufts 18 interconnect the tufted geotextile 14 to the formwork 20 by the anchoring secure engagement to the infill 30.

[0034] Fig.1A illustrates the land site 12 having a geomembrane ground cover 21 overlaid by the anchored load-bearing revetment structure 10 as an alternate embodiment of the ground cover system in accordance with the present invention. The impermeable geomembrane 21 restricts ambient environmental water such as rain or snow-melt precipitation from inflow or seepage below ground. Rather, the ambient water flows over the geomembrane, for example to water flow channels.

[0035] Fig. 3 illustrates the formwork 20 in perspective view overlying a portion of the tufted geotextile 14 that covers the ground surface of the land site 12. The vessels 22 have a geometric shape, in the illustrated embodiment are cylindrical members, interconnected by the span members 4890-3995-7486v1 2171320-00016510 / 10 / 202424. The formwork 20 in the illustrated embodiment comprises first and second adjacent 6-vessel by 6-vessel gridwork 23a, 23b of rows and columns, but any practical number may be used subject to forming, transportation, and installation limitations. The vessels 22 may be in ordered spaced- relation or irregular spacing. The height of the formwork 20 can range from 0.5 inches to 8.0 inches. A transverse width of the geometric shape of the vessels 22 ranges from 1 inch to 8 inches.

[0036] Fig.4 illustrates a detailed view of the formwork 20 shown in Fig.3 with a portion of the plurality of tufts 18 of the tufted geotextile 14 extending upwardly in the open vessels 22 of the formwork, which tufts interconnect the tufted geotextile to the formwork in the anchored load- bearing revetment structure 10.

[0037] Fig.5 illustrates the formwork 20 receiving the infill 30 onto the tufted geotextile 14 and covering the tufts 18 for interconnecting the tufted geotextile to the formwork in the anchored load-bearing revetment structure 10. The formwork 30 receives the infill 30 to the upper edge of the open vessels 22 for defining the upper surface of the anchored load-bearing revetment structure 10. Some of the infill 30 may extend above the height of the formwork 20. Fig.5 illustrates some of the vessels 22 with upper edges partially showing with portions covered by the infill 30. The excess infill 30 may be left in place or broom-swept for defining a more level surface over the formwork 20. The infill 30 may comprise an aggregate infill, a cementitious mixture infill, and / or a bound infill material. A bound infill provides infill particles mixed with a binder. The infill may be placed either dry or wet. The infill 30 inter-engages with the tufts 18 and preferably solidifies to secure the embedded tufts 18 therein for interconnecting the tufted geotextile 14 with the formwork 20 and forming the anchored load-bearing revetment structure 10. The anchored load- bearing revetment structure 10 provides a stable structure for traffic loading or high impact resistant roadway, bridging, water channel, erosion control, or waterway revetment. In an alternate 4890-3995-7486v1 2171320-00016510 / 10 / 2024embodiment however, such as for a temporary or short-term installation for example as a utility vehicle or foot traffic crossing, an infill comprising a soil material densely packed into the formwork 20 provides a satisfactory anchoring engagement of the formwork 20 with the tufted geotextile 14. The soil material may comprise clay.

[0038] Fig. 6 illustrates the formwork 20 filled with the infill 30 receiving water generally 31 sprayed over and into the infill (such a cementitious material infill receiving water for curing to a solid). The wetted infill covering the tufted geotextile 14 and the tufts 18 cures to the solid for interconnecting the tufted geotextile 14 anchored by the plurality of tufts 18 to the formwork in the anchored load-bearing revetment structure 10.

[0039] Fig. 7 illustrates the solidification of the infill 30 that interconnects the tufts 18 of the tufted geotextile 14 to the formwork 20 in the anchored load-bearing revetment structure 10. Some of the span members 24 are illustrated in broken line showing the span members within and covered by the infill 30.

[0040] The formed solidified load-bearing revetment structure 10 provides a multi-layer, hard armor revetment system for load-bearing use by vehicles, maintenance equipment, as well as resisting impact from debris and the dry or fluidal hydraulic forces of wind and ambient water flow over the ground covering tufted geotextile 14.

[0041] The underlying tufted geotextile 14 connects through the upwardly extending tufts 18 within and to the infill 30 within the three-dimensional confining layer of the formwork 14. The tufts 18 thereby define vertically extending flexible anchors extending into and reinforcing the infill 30. This creates a three-dimensional revetment structure 10 with superior structural and compressive strength for heavy traffic, high loading, and significant impact applications such as 4890-3995-7486v1 2171320-00016510 / 10 / 2024landfill roads, levee low water crossings, pipeline crossing, debris-laden and hydraulic applications (channels, flumes, embankments) of water flow streams and shores of rivers, lakes, and harbors, while resisting impact from dam overtopping and hydraulic energy dissipation.

[0042] In an alternate embodiment illustrated in Fig. 1A, the impermeable geomembrane 21 underlies the tufted geotextile ground cover 14. The impermeable geomembrane 21 restricts ambient environmental water such as rain or snow-melt precipitation from inflow or seepage below ground. Rather, the ambient water flows over the geomembrane, for example to water flow channels. An installation of the anchored revetment structure 10 using the impermeable geomembrane 21 covering the ground surface reduces or eliminates the need for drains used under traditional systems.

[0043] In an alternate embodiment illustrated in cross-sectional exploded view in Fig. 8, the ground surface first receives a covering particulate base 36 on which the tufted geotextile 14 is placed. The particulate base 36 comprises an aggregate such as sand, gravel, rock, clay, soil, and mixtures, a sand mixture, a sand-binder infill mixture, or a cementitious mixture and binder. The particulate base 36 is applied over the ground surface for a depth in a range between 0.25 inches to 1.5 inches. The particulate base 36 provides a leveler for smoothing surface variations of the ground and to provide a foundational consistent covering base on which the tufted geotextile sits. The yarns that pass through the sheet or web 16 (see cut-away) to form the turfs 18 extend across a bottom surface of the tufted geotextile as bridges 38 between adjacent tufts. The bridges 38 may engage and dig into the particulate base 36. This assists in locking the tufted geotextile 14 to the particulate base 36 and resisting lateral movement of the tufted geotextile during installed use of the revetment structure 10. Fig. 8 further illustrates an alternate embodiment that covers the 4890-3995-7486v1 2171320-00016510 / 10 / 2024particulate base 36 with a geomembrane 21. This embodiment resists inflow of ambient environmental water into the particulate base 36.

[0044] With reference to Fig. 1 and other of the figures as noted, the anchored load-bearing revetment structure 10 readily assembles in land site installation. The tufted geotextile 14 is placed over the land site surface. The large area land site may be covered, such as a land fill. A smaller area tufted geotextile may be overlaid in a swale for forming a vehicle cross-over. An elongated tufted geotextile may be overlaid in a water flow ditch or culvert for forming a stabilized flow channel.

[0045] As shown in Fig.3, the formwork 20 installs on the upper surface of the tufted geotextile 14, and the turf fibers 18 extend upwardly as shown in detail in Fig.4 through the open bottom of the vessels 22 into the interior space. In reference to Fig.5, the securing infill 30 is spread over the formwork. The particles of the infill fall onto the upper surface of the tufted geotextile and around the upstanding tufts. Excess infill above the vertically upper extent of the formwork may be left in place or broom-swept to define a more uniform surface. The infill is allowed to solidify. For a cementitious dry mix, water is sprayed (Fig. 6) over the infilled formwork. The infill solidifies as shown in Fig.7 and engages the tufts and the walls of the vessels. This locks the tufts into the infill and the tufts become anchors holding the tufted geotextile to the formwork.

[0046] Fig. 9 illustrates the anchored load-bearing revetment structure 10 of the present invention providing a passage structure 50 or road crossing over a portion of the tufted geotextile 14 for travel passage of an on-site construction or maintenance utility vehicle 52. The revetment structure 10 installs at swales or slope transitions. The anchored load-bearing revetment structure 10 facilitates access to a covered land site by service and inspection personnel using the utility vehicle 52 for on-site inspections and for carrying of tools and equipment. Further, the anchored 4890-3995-7486v1 2171320-00016510 / 10 / 2024load-bearing revetment 10 resists hydraulic shear flow of ambient environmental water from rainfall or snow melt-off of often steeply sloped covered ground surfaces.

[0047] Fig. 10 illustrates the anchored load-bearing revetment structure 10 applied as a shore- line revetment 60 or slope erosion control covering overlying a shoreline generally 62 of a body of water 64 such as a river, water flow channel, pond, lake, levees, dams, ocean shore, or other water / ground interface. The tufted geotextile 14 overlies the shoreline 62. An edge 63 of the tufted geotextile 14 may be seated in an elongated trench 66 dug along the shoreline 62. The tufted geotextile 14 extends upslope therefrom away from the body of water. A plurality of the formworks 20 overlie the tufted geotextile 14 from proximate the shoreline 62 to a distal upslope edge 68 defined by the uppermost line of formworks 20. The illustrated embodiment shows three lines of spaced-apart formworks 20. As discussed above, a portion of the tufts 18 extend upward in the open vessels 22. The formworks 20 are filled with the infill 30 and cured for engaging the tufts 18 to the load-bearing revetment structure 10 as anchors. The revetment structure 10, secured with the engaged tufts 18 to the tufted geotextile 14, resists slope erosion from wave action along the shoreline

[0048] Fig. 11 illustrates the anchored load-bearing revetment structure 10 of the present invention as a lining for a water flow channel 70 for flow of water 71 across a land site 72. The water flow channel 70 may be downslope from an apex to a foot of a slope, or formed along a contour or a sloping contour for controlling water flow off of a sloped land site such as a bench portion of a sloped land site. In the illustrated embodiment, the water flow channel 70 shown in cross-sectional forms a wide U-shape with opposing sides 74, 76 and a base flow surface 78 having a width 80 and a depth 82. An exemplary but not limiting channel may have sides 74,76 that angle upwardly and outwardly from the base flow surface 78 defining a channel with a width of eight 4890-3995-7486v1 2171320-00016510 / 10 / 2024feet and a depth of four feet as a wide U shape in cross-section. A portion of the tufts 18 of the tufted geotextile stand within the vessels 22 as shown in cut-away and as discussed above, and upon curing of the infill secure the formworks 20 to the tufted geotextile 14 covering the land site.

[0049] The forgoing discloses an anchored load-bearing revetment structure 10 having superior structural and compressive strength for both heavy traffic, high loading, and significant impact applications including but not limited to landfill roads, levee low-water crossings, pipeline crossing, debris-laden and hydraulic applications (channels, flumes, embankments, swales and ditches), dam overtopping flow aprons, and hydraulic energy dissipation. The underlying geotextile 14 anchors by the extending tufts 18 in the vessels 22 or passageways filled with the infill 30 whereby the extending tufts engage in the infill that also engages the walls of the open three-dimensional passageways of the confining layer formwork 20, for a stabilized pad overlying the tufted geotextile.

[0050] The foregoing discloses illustrative embodiments of the load-bearing revetment structure inter-engaged with tufts of the ground covering tufted geotextile for a pathway for passage of utility vehicles and personnel across the covered ground surface. Variations and modification will be readily apparent to persons of ordinary skill in the art in view of the various illustrative embodiment presented in the disclosure. 4890-3995-7486v1 2171320-00016510 / 10 / 2024
