The present invention provides an erosion protection layer for use in embankments, ditches, flood levees, waterways, lower steep troughs, landfills, and other steep terrain conditions exposed to shear forces of water and wind.

In one embodiment of the invention, the synthetic grass is used in combination with the bonded/stabilized filler ballast to provide a new and useful floor covering system while also providing a beneficial erosion protection system that does not require maintenance. This combination (sometimes referred to as composite material) can be used to cover slopes and to lining drainage drains, beach troughs, and lower steep troughs. With the coating system of the present invention, the owner and the operator can achieve significant cost savings by constructing the coating system with synthetic grass that does not require plant support and does not require the prior art top layer typical of the prior art coating system.

More particularly, in a first example form, the invention includes a synthetic floor covering system for erosion control to be placed on top of the ground, comprising one or more of a composite fabric comprising tufted synthetic yarns. Synthetic grass of complex. The synthetic floor covering also contains stabilized/combined filler ballast applied to the synthetic grass (stabilized against high speed water shear).

Optionally, the filler ballast comprises sand or soil and is combined with a binder such as cement, mortar, lime or the like.

Using the present invention, the system can be used to line the lower chutes and ditches against the large shear forces of water and wind without scouring the soil beneath the system. Artificial turf provides separation of the sand filler from the underlying ground and the turf blade acts as a structural reinforcement for the sand filler while providing aesthetic appeal The surface of pleasure. The sand filler on top is stabilized by the binder applied to the sand filler from being washed away or blown away, and the binder typically has the effect of cementing or bonding the sand together. This allows the invention to resist shear forces from water or wind. In this regard, the bond strength does not have to be extremely high. In fact, it is not necessary to achieve structural strength as large as, for example, concrete. Alternatively, the binder only holds the sand together to resist the wind and water erosive forces. In this regard, the sand/soil is bonded to other sand particles and/or to synthetic turf leaves by a binder.

1 is a schematic cross-sectional view of an exemplary synthetic floor covering system 110 for erosion control in accordance with the present invention and showing the surface of soil S coated with the ground covering erosion control system of the present invention. The system includes a synthetic turf 140 comprising a liner 142 and a synthetic turf blade 141 secured to the liner. A stabilized/combined sand/soil filler 160 is placed in the bottom of the synthetic turf 140 above the liner 142. The soil S may be covered with a sand subgrade, a gravel roadbed or an intermediate covering prior to laying the synthetic floor covering system 110 for erosion control, as desired. In this first exemplary embodiment, the synthetic turf 140 is placed more or less directly on top of the soil S. As will be seen below, the system can also have additional components interposed between the soil S and the turf 140.

Preferably, synthetic turf 140 is used as the primary component of the synthetic floor covering system. It can be constructed using a braiding machine or a tufting machine that can use, for example, more than 1,000 needles to create a turf width of about 15 feet. Preferably, the synthetic turf comprises synthetic grass blades 141 that are tufted to have a blade length of between about 0.5 inches and 4 inches (which comprises polyethylene monofilament and/or diced film fibrillated fibers or non-fibrillated fibers) fiber). Other polymers can be used to synthesize grass blades as needed. Preferably, the tufted synthetic grass blades 141 have a blade length of between about 1.5 inches and 3 inches. Most preferably, the synthetic grass blades 141 are clustered to have a blade length of about 1.5 inches. Optionally, the tufted synthetic grass blade 141 has a density of between about 20 ounces per square yard and about 120 ounces per square yard. Preferably, the synthetic grass blade has a thickness of at least about 100 microns.

The synthetic grass blades 141 are clustered into a substrate or liner 142 comprising a synthetic woven or non-woven fabric. Further, the liner may be a single layer liner or a multilayer liner, as desired. Optionally, the geomembrane filter can be secured to the substrate to reinforce the substrate and preferably secure the synthetic grass blade.

The chemical composition of the synthetic turf component should be selected to resist degradation due to exposure to sunlight, which generates heat and contains ultraviolet radiation. The polymer yarn should not become brittle when subjected to low temperatures. The choice of synthetic grass color and texture should be aesthetically pleasing.

The actual grass component is preferably comprised of green polyethylene fibers 141 that are tufted into a woven or non-woven fabric having a length of from about 1.5 inches to about 2.5 inches. For additional strength in very steep side slopes, additional filter element assembly liners can be clustered for improved dimensional stability. The polyethylene straw 141 preferably has a long-term operational life of at least 15 years.

A sand/soil layer 160 of about 0.5 inches to about 2.0 inches is placed as a filler on top of the synthetic turf to ballast the material and protect the system against wind uplift and dimensional stability. Preferably, the filler is between about 0.5 inches and 1 inch. The sand/soil layer provides additional protection from the UV fabric. In addition, sand/soil ballast is bonded with cement, mortar, lime or another binder to resist the shear of water and wind on steep side slopes, drains and lower channels. In this regard, the synthetic turf 140 is first placed over the ground and then the sand/soil filler is spread over the synthetic turf in dry form. This allows the dry filler material to be easily and effectively submerged into the bottom of the synthetic turf. Thereafter, the filler is watered (e.g., by spraying water over the turf) and allowed to cure into a hardened, bonded filler layer. In this regard, the sand/soil filler is bonded to itself and to individual blades of the synthetic turf. Thus, in the event that the bonded filler breaks at some location, the individual blades of the turf act as anchors and help hold the bonded filler in place.

The "sand/soil" filler contains real sand (including strontium sand, quartz sand, etc.), earth, clay, mixtures thereof, etc., which also contain articles similar to sand or earth. For example, it can be used Granular tailings from quarry (similar to granular marble, quartz, granite, etc.). In addition, small gravel can be used as a "sand/soil" filler. In this regard, preferably, the filler is inorganic in nature so that it is extremely stable and lasts for a long time. However, organic particulate materials may be employed in certain applications. Further, the binder may be inorganic or organic. Preferably, the binder is inorganic (again, for stability and long life). Cement, mortar, liming agent, etc. are well suited for this application. However, other binders such as organic binders may be employed. For example, a polymer based binder (for example, a urethane product) can be used. In fact, recently, spray bonding agents for incorporating small gravel into the path have been marketed under the trade name "Klingstone" and sold by Klingstone Corporation of Waynesville, North Carolina.

Applicants have found that about three parts of sand and one part of the cement work well as a dry filler. Once wetted and cured, the bonded sand filler provides resistance to erosion that is caused by the wind and is superior to the turf and is also resistant to damage or erosion from wind or rain or high water flow. Approximately equal parts of sand and cement also played a good role, as did the ratio between these two examples. However, for economic reasons, it is desirable to use as much cement as is needed to hold the filler together and hold it to the synthetic turf blade, as cement is more expensive than sand (generally). Thus, a location near 3:1 is generally more economical but has a lower strength, while a side close to 1:1 is generally stronger but more expensive. In addition, sand/cement/lime 2:2:1 also plays a good role. In addition, fly ash can be used instead of lime.

Advantageously, the invention may be used even where a high concentration flow is desired (e.g., a lower steep channel, a large drainage channel). For this purpose, binders such as cement, mortar, lime, etc. are used to stabilize the sand/soil filler. This formation is more or less grouted or combined with sand/soil filler 160 to resist the shear of water or wind.

The present invention combines synthetic grass to provide a pleasing visual appearance that requires minimal maintenance erosion protection. The invention incorporates a bonded filler that can be disposed of with synthetic grass Extremely fast water runoff. Thus, the coating system of the present invention can be installed on extremely steep slopes that are commonly found in embankments, flood levees, dams, lower steep troughs, landfills, and material piles. The system can be used as an erosion control material that resists the shear forces of water or wind.

In addition to the embodiments set forth above, the system can take other forms as well. For example, the system can include a membrane having a drainage layer overlying a synthetic turf having a cemented (stabilized) filler using any of the binders set forth herein and the like. In this embodiment, the bottom layer comprises a structured low permeability membrane (as the case has a textured or pointed on the bottom side and a drainage column on the top side) and a top layer. The top layer may comprise turf (for example, having a 1.5 inch pile height) and a filler of sand, lime and cement mixture. In one example, the filler can be a 0.75 inch mixture.

2 is a schematic cross-sectional view of a synthetic floor covering system 210 for erosion control in accordance with a second example of the present invention showing an open mesh grid drainage system at the bottom of the system. The exemplary embodiment is similar to FIG. 1, FIG. 2 shows an example of the coating for erosion control system 210 for controlling the erosion of the soil S. System 210 includes a lower filter fabric (ground filter) 220, an open grid or geonet 230, and a synthetic turf 240. The synthetic turf 240 includes a liner 242 and a blade 241 secured to the liner. The stabilized/combined sand/soil filler 260 is placed in the bottom of the synthetic turf 240 above the liner 242. The soil S may be covered with a sand roadbed, a gravel roadbed or an intermediate covering prior to laying the synthetic floor covering system 210 for erosion control, as desired. Preferably, the lower filter fabric 220 comprises a woven or non-woven synthetic fabric. In some applications, the lower filter fabric 220 can be replaced with a barrier film having a low permeability barrier.

3A and 3B illustrate a synthetic floor covering system 310 for erosion control in accordance with a third example of the present invention, shown without an open mesh grid at the bottom of the system. Similar to the exemplary embodiment of FIG. 1, the exemplary coating system 310 for erosion control shown in these figures is used to control erosion of soil S. System 310 includes an impervious membrane 350 and a synthetic turf 340. The impervious geomembrane 350 is a polymeric thin layer having elongated tips on the bottom surface and wedge-shaped or columnar agglomerates on the top surface. For example, see upper agglomerates 351 through 354 and spikes 357 through 359. The lower spikes help anchor the impermeable membrane to the soil S and the upper agglomerates help anchor the synthetic turf 340 to the impervious membrane 350. The upper agglomerates also provide a penetrating drainage layer or space in which water can flow over the film under the synthetic turf. The synthetic turf 340 includes a pad 342 and a blade 341 secured to the pad. The stabilized/combined sand/soil filler 360 is placed in the bottom of the synthetic turf 340 above the liner 342.

4 is a schematic cross-sectional view of another synthetic floor covering system 410 for erosion control in accordance with the present invention, shown with a reinforcement layer on a synthetic turf pad. The exemplary embodiment is similar to FIG. 1, FIG. 4 shows an example of a coating for erosion control system 410 for controlling the erosion of the soil S. System 410 includes a synthetic turf 440 that includes a liner 442 and a blade 441 secured to the liner. Pad 442 can be a single layer liner or a multilayer liner. The urethane barrier 443 is applied to the underside of the liner 442 and functions as both a reinforcing liner and a connection between the blade 441 and the liner 442. The urethane barrier 443 also renders the liner 442 generally watertight. The stabilized/combined sand/soil filler 460 is placed in the bottom of the synthetic turf 440 above the liner 442.

5A and 5B show an exemplary embodiment of FIG. 1 applied to a topography of a varying slope. The synthetic floor covering system 110 has the ability to handle high intensity precipitation and avoid erosion of sand/soil filler ballast and/or turf ranging from 1 lb./ft. to 25 lb./ft. Shear stress.

Applicants have found that sand as a primary ballast particularly works well, but soil also plays a good role. Even small gravel can be used as the primary ballast. In addition, Applicants have discovered that the binder that works best in most applications is cement, but other binders can also function. Therefore, although cement-based materials are preferred binders, other materials may also kick in.

Figure 6A is a schematic cross-sectional view of a synthetic floor covering system 610 for erosion control in accordance with another example of the present invention. Similar to the exemplary embodiment of FIG. 1, a ground covering system 610 for erosion control is used to control erosion of soil S. System 610 generally includes a synthetic turf 640 that includes a liner 642 and a blade 641 secured to the liner. Pad 642 can be a single layer or multiple layers of padding. An impermeable liner or layer 650 is applied to or formed on the underside of the liner 642 and functions to both strengthen the liner 642 and the connection between the blade 641 and the liner 642. Preferably, the impermeable layer 650 is such that the liner 642 is generally impervious to water, thereby preventing water or other liquid present on the liner 642 from immersing in the soil S. The filler ballast 660 is applied to the synthetic grass on the top of the liner and the bonding agent is applied to the filler ballast to protect the filler ballast against high velocity water shear.

Preferably, the impermeable layer or liner 650 comprises a geotextile. Optionally, the impermeable layer 650 includes a permeable work fabric and an impermeable polymer applied to the permeable work fabric to render the layer 650 impermeable. The impermeable polymer includes polyethylene, polypropylene, polyurethane, EPDM or PVC, as appropriate. In one form, the impermeable polymer is sprayed onto a permeable work fabric and then cured. Optionally, the impermeable polymer is laminated, glued, coated or otherwise applied to the permeable work fabric. In an example form, the impermeable liner 650 is substantially non-planar for gripping a non-horizontal, sloped ground (see Figure 6B).

In one alternative form, the solid element can be incorporated with the impermeable polymer to provide greater grip when the ground covering system 610 is placed on a non-horizontal, sloped surface. For example, in one form, a plurality of solid or pointed support articles are placed on a permeable work fabric and an impermeable polymer is applied to the permeable work fabric, thus the plural An article is attached to the permeable work fabric to provide a non-flat, impermeable layer 650. In another alternative form, the plurality of articles are incorporated into the impermeable polymer and attached to the permeability when the impermeable polymer is sprayed or applied to the permeable work fabric. Geotextile. In yet another alternative form, a generally thin grid-like assembly comprising a plurality of spikes or extruded members is placed on top of the permeable work fabric and an impermeable polymer is applied to the grid On top of the assembly, the grid-like component is thereby attached to the impermeable layer 650.

Preferably, by providing a non-flat, impermeable layer 650 attached to the ground covering system 610, the ground covering system 610 can be installed in a single step on a non-horizontal, sloped ground, which can be considered to reduce manufacturing and installation costs.

There are many advantages to the coating system of the present invention. The coating system reduces construction costs, reduces annual operating and maintenance costs while providing superior and reliable/consistent aesthetics. It also reduces the need for expensive anti-scouring stone channels and drainage platforms, and does not substantially have erosion or siltation problems even during inclement weather. It is a good choice in sensitive areas where soil erosion and sedimentation are the main concerns, as soil erosion is substantially reduced. It also eliminates the need for siltation tanks and associated environmental structures. It allows for steeper slopes due to the risk of reduced soil stability problems.

While the present invention has been shown and described with respect to the embodiments of the invention, it will be understood that many modifications can be made therein without departing from the spirit and scope of the invention as defined by the following claims. Add and delete.
