(12) As used herein, the singular forms a, an, and the include plural references unless the context clearly dictates otherwise. The terms comprising, including, and having are intended to be inclusive and mean that there may be additional elements other than the listed elements. The terms optional or optionally means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event occurs and instances where it does not.

(13) Embodiments of the present disclosure are directed to a sediment control device including an elongate fabric and a plurality of sleeves attached to the fabric. The plurality of sleeves extend generally perpendicular to a longitudinal axis of the fabric and are configured to receive a stake for securing the sediment control device to soil. Each sleeve is spaced a predefined distance from an adjacent sleeve. In use, the fabric is extended along a soil path, a bottom portion of the fabric is trenched into soil, and the stake is inserted into each sleeve such that the sediment control device is secured to soil, and the fabric is stretched between inserted stakes. The bottom portion can then be backfilled.

(14) As shown in FIGS. 1 through 4, a sediment control device, indicated generally at 100, of the present disclosure includes an elongate fabric 120 and a plurality of sleeves 150 attached to the elongate fabric. Each of the plurality of sleeves 150 are configured to receive a stake 190 for securing the elongate fabric 120 to soil.

(15) The elongate fabric 120 of the exemplary embodiment shown in FIGS. 1-4 is an elongate, flexible, rectangular sheet having a front 122 (FIG. 2) and a back 124 (FIG. 1), a top edge 126 and a bottom edge 128, and a first lateral edge 130 and a second lateral edge 132. With reference to FIG. 3, the top edge 126 and bottom edge 128 define a height H of the elongate fabric 120. The first lateral edge 130 and second lateral edge 132 define a length L of the elongate fabric 120. A longitudinal axis Y extends along the length L of the elongate fabric 120. It is understood that the elongate fabric 120 of the illustrated sediment control device 100 can have any suitable height H and length L without departing from some aspects of this disclosure. For example, the elongate fabric 120 can have a height H in the range of 1 foot to 4 feet, and a length L in the range of 25 feet to 1500 feet. In some embodiments, the height H is in the range of 3 feet to 6 feet. In some embodiments, the length L is in the range of 5 feet to 8 feet, 7 feet to 10 feet or 9 feet to 12 feet. In some embodiments, the elongate fabric 120 is a continuous roll.

(16) In some embodiments, the elongate fabric 120 can be of a soil-impermeable or water-impermeable material so that soil or water from a construction site does not permeate thought the elongate fabric 120 and cross into nearby grounds or ecosystems. In some suitable embodiments, the elongate fabric 120 includes a support structure 180 attached to the back 124 of the elongate fabric. In some other suitable embodiments, the elongate fabric 120 includes a support structure 180 attached to the front 122 of the elongate fabric. The support structure 180 can be attached to either the front 122 and/or back 124 of the elongate fabric to add rigidity to the elongate fabric 120 or to otherwise structurally support the sediment control device 100. In some suitable embodiments, the support structure 180 is a wire mesh or a wire matrix.

(17) As shown in FIGS. 1 and 3, each sleeve 150 of the plurality of sleeves is attached to the back 124 of the elongate fabric 120. As seen therein, each sleeve extends generally perpendicular to the longitudinal axis Y and is configured to receive a stake 190 for securing the sediment control device 100 to soil 102 (as shown in FIG. 6). In some suitable embodiments, each sleeve 150 of the plurality of sleeves is formed integrally with the elongated fabric 120. In some other suitable embodiments, each sleeve 150 of the plurality of sleeves is welded (or otherwise suitably attached) to the back 124 of the elongate fabric 120. With reference to FIG. 2, each sleeve 150 of the plurality of sleeves is positioned a predefined distance D L from an adjacent sleeve of the plurality of sleeves 150. In some embodiments, the predefined distance D L is in the range of 10 feet to 20 feet. In some embodiments, the predefined distance D L is in the range of 1 foot to 4 feet, 3 feet to 6 feet, 5 feet to 8 feet, 7 feet to 10 feet or 9 feet to 12 feet. In some embodiments, the predefined distance DL is in the range of 12 feet to 16 feet.

(18) In some suitable embodiments, each sleeve 150 is formed integral with the elongated fabric 120 by folding the elongate fabric and bonding near the fold. The resulting sleeve 150 and elongate fabric 120 has an omega-shaped () cross-section. In some other suitable embodiments, as shown in FIG. 4, each sleeve 150 is formed by looping a discrete sleeve fabric 152, which is formed separately from the elongate fabric 120, and attaching (e.g., by sewing, welding, or bonding) an outer surface 154 of the sleeve 150 to the back 124 of the elongate fabric. In some embodiments, as shown in FIG. 4, lateral ends (156, 158) of the sleeve fabric 152 are folded over each other and bonded together to form each sleeve 150. In some embodiments, lateral ends (156, 158) of the sleeve fabric 152 are connected together to form each sleeve 150. It is contemplated the sleeves 150 can be made from the same material or different material than the elongate fabric 120.

(19) Referring to FIG. 3, in some embodiments, each sleeve 150 of the plurality of sleeves extends a distance D.sub.1 from the top edge 126 of the elongate fabric 120. The distance D.sub.1 from the top edge 126 of the elongate fabric 120 defines a top portion 160 of the elongate fabric 120. Likewise, a bottom portion 162 of the elongate fabric 120 extends from the bottom edge 128 to the top portion 160 of the elongate fabric 120. As explained in further detail below with reference to FIGS. 5-7 and 9A-9C, the bottom portion 162 of the elongate fabric 120 can be at least partially trenched into soil 102. In some embodiments, the plurality of sleeves 150 extend from the top edge 126 to the bottom edge 128 of the elongate fabric 120, and the bottom edge 128 is positioned against the soil 102. In some embodiments, the distance D.sub.1 from the top edge 126 of the elongate fabric 120 is in the range of 2 feet to 3 feet. In some embodiments, the plurality of sleeves 150 extend 20% the length L of the elongate fabric 120. Stated differently, in some embodiments, the distance D.sub.1 is 20% the length L of the elongate fabric 120. In some embodiments, the distance D.sub.1 is in the range of 20% to 80% the length L of the elongate fabric 120. In some embodiments, a first sleeve 150 of the plurality of sleeves has a distance D.sub.1 different from a distance D.sub.1 of a second sleeve 150 of the plurality of sleeves. Stated differently, in some embodiments, the plurality of sleeves 150 can have different distances D.sub.1.

(20) In some suitable embodiments, the support structure 180 extends from the top edge 126 of the elongate fabric 120 to the bottom portion 162. In some other suitable embodiments, the support structure 180 extends partially into the bottom portion 162 such that only a portion of the support structure 180 is partially trenched into soil. It is contemplated that that no portion of the support structure 180 would be trenched into the soil during use. That is, the support structure 180 would be disposed above the soil during use. As mentioned above, in some suitable embodiments, the support structure 180 can be omitted from the sediment control device 100.

(21) Referring to FIGS. 5-7, in use, the bottom portion 162 of the elongate fabric 120 is suitably trenched into soil 102. Due to the flexibility of the elongate fabric 120, the bottom portion 162 of the elongate fabric 120 can be forwardly bent relative to the front 122 of the elongate fabric 120, providing further support to the sediment control device 100. After trenching and backfilling the bottom portion 162 of the elongate fabric 120 into soil 102, the stakes 190 can be inserted into the plurality of sleeves 150 and driven into the soil 102. In the illustrated embodiments, the sediment control device 100 extends along a straight path. In some embodiments, the sediment control device 100 can extend along a curved path due to the flexibility of the elongate fabric 120.

(22) As shown in FIG. 7, each stake 190 has a length Ls greater than the distance D.sub.1 of the plurality of sleeves 150 such that the stakes 190 extend beyond the top edge 126 of the elongate fabric 120. Thus, driving the stakes 190 into soil 102 does not damage the elongate fabric 120 or the plurality of sleeves 150. The stakes 190 are driven into the soil 102 by a distance Ds such that the sediment control device 100 is properly secured to the soil 102. The stakes 192 can be secured to the elongate fabric 120 by a securement structure 191 at one or more points along the elongate fabric 120. The securement structure 191 can be, for example, a zip tie, a staple, a wire, or a rebar tie which is passed through the elongate fabric 120.

(23) As shown in FIG. 8, in some embodiments, the sediment control device 100 further includes a removable insert 192 which can be inserted into each sleeve of the plurality of sleeves 150 prior to inserting the stake 190. The removable insert 192 is made from a rigid plastic and has a hollow cylindrical body. The removable insert 192 has an inner diameter D.sub.I greater than a diameter D of the stakes 190 and the removable insert 192 has an outer diameter Do lesser than a diameter D.sub.V of the plurality of sleeves 150. Because the sleeve fabric 152 of the plurality of sleeves 150 is flexible, the removable insert 192 causes the plurality of sleeves 150 to form a circular cross-section for aiding in insertion of the stakes 190. Where the stakes 190 are made of wood, the removable insert 192 reduces splintering of the stakes 190 during insertion of the stakes 190 into the plurality of sleeves 150. The removable insert 192 can be removed from each sleeve of the plurality of sleeves 150 after the stake 190 is inserted into the removable insert 192. In the illustrated embodiment, a bottom end 194 of the removable insert 192 has flat cross-section (perpendicular to a length of the removable insert 192). In some embodiments, the bottom end 194 is cut at an oblique angle to aid in insertion of the removable insert 192 into each sleeve of the plurality of sleeves 150. In some embodiments, the bottom end 194 has a V-shape.

(24) FIGS. 9A through 9C illustrate steps of a method of installing the sediment control device 100 into soil 102. As shown in FIG. 9A, the method includes trenching or digging a trench 104 into the soil 102 along a soil path and placing the bottom edge 128 of the elongate fabric 120 on the soil 102 such that at least the bottom portion 162 of the elongate fabric 120 is placed within the trench 104. As shown in FIG. 9B, the method further includes inserting a stakes 190 into each sleeve of a plurality of sleeves 150 and driving the stakes 190 into the soil 102 to secure the elongate fabric 120 to the soil 102.

(25) As shown in FIG. 9C, the method further includes backfilling the trench 104 with additional soil 106 to fill the trench 104 and bury the bottom portion 162 of the elongate fabric 120 into the soil 102. In some embodiments, the method further includes securing the stake 190 to each sleeve of the plurality of sleeves 150 with the securement structure 191. In some embodiments, the method further includes inserting the removable insert 192 of FIG. 8 into each sleeve of the plurality of sleeves 150 prior to inserting the stake 190 into each sleeve of the plurality of sleeves 150 and, removing the removable insert 192 from each sleeve 190 of the plurality of sleeves 150. In some embodiments, a shovel is used for trenching and backfilling the trench 104, and a hammer or maul is used for driving the stakes 190 into the soil 102. In some embodiments, a rotary hammer is used for driving the stakes 190 into the soil 102.

(26) In use, the elongate fabric 120 of the sediment control device 100 is initially rolled up into a roll and one or two laborers can extend the first lateral edge 130 and the second lateral edge 132 of the elongate fabric 120 along the soil path. The elongate fabric 120 is then held upright at each sleeve of the plurality of sleeves 150 and a stake 190 is driven through each sleeve and into soil 102. Because each sleeve of the plurality of sleeves 150 are positioned the distance DL from adjacent sleeves (of FIG. 2), laborers do not have to pre-measure stake insertion points along the soil path. Furthermore, because the stakes 190 are already attached to the elongate fabric 120 by the plurality of sleeves 150, only one securement structure 191 (of FIG. 7), is needed to secure the stakes 190 to the elongate fabric 120, further reducing labor time during installation of the sediment control device 100.

(27) A sediment control kit can include the elongate fabric 120 and plurality of sleeves 150 rolled into a roll, and the stakes 190 can be bundled up separately. Because the roll does not include the stakes 190, the roll has a significantly lesser diameter than conventional sediment control devices with pre-attached stakes. In some embodiments, the sediment control kit further includes securement structures 191 in a separate container. In some embodiments, the sediment control kit further includes the removable insert 192, or a plurality of removable inserts.
