DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(30) Embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

(31) Referring to the drawings and, in particular, FIGS. 1-8B, a drainage system 14 having an open-faced channel 15 is illustrated prior to being placed in a preformed trench and secured with a curable medium 13 (which may also be referred to herein as moldable composition), as can be seen in FIG. 3. The curable medium 13 may be a pourable mixture such as cement, which may include various cementitious materials. The open-faced channel 15 has a first and second end member 17, 18 and a first and second lateral side 19, 20, as shown in FIG. 1. Individually, each end member 17, 18 and lateral side 19, 20 is a sidewall of the open-faced channel 15, and collectively, the first and second end members 17, 18 and first and second lateral sides 19, 20 make up the sidewalls 21, where the lateral sides 19, 20 and end members 17, 18 are connected at the edges in a substantially perpendicular manner to form a rectangular shape.

(32) In particular, the first end member is 17 attached to one end of the first and second lateral sides 19, 20, and the second end member 18 is attached to the opposing second end of the first and second lateral sides 19, 20. In this way, the lateral sides 19, 20 are substantially parallel to each other and the end members 17, 18 are substantially parallel to each other, such that the first and second lateral sides 19, 20 and the first and second end members 17, 18 are spaced apart by predetermined distances to define an interior space therebetween. In an exemplary embodiment, the distance between the first and second lateral sides 19, 20 may be 8-14 inches, and the distance between the first and second end members 17, 18 may be 20-45 inches. It should be understood that the foregoing dimensions are provided for illustrative purposes only, and that it is fully within the scope of the present disclosure for other dimensions to be used as required by the applications for which the drainage system is to be used. As shown in FIG. 2C and 8B, the drainage system 14 can also include a bottom wall 22, whereby the sidewalls 21 extend upwardly from opposite sides of the bottom wall 22.

(33) As best shown in FIGS. 1, 2A-2C, and 3-5, the sidewalls 21 preferably include one or more anchor flanges 24 extending along the length of the sidewalls 21 to retain the position of the drainage system 14 when the curable medium 13 is poured around the open-faced channel 15. Typically, the curable medium 13 is poured to a level that rises above the anchor flanges 24 such that the anchor flanges 24 become embedded within the curable medium 13 once the curable medium 13 has hardened. The anchor flanges 24 are preferably continuous and integrally formed in the sidewalls 21 to facilitate the retention of the position of the open-faced channel 15 within the curable medium 13.

(34) As best shown in FIGS. 1, 2A, and 2C, the open-faced channel 15 may comprise one or more installation legs 28 that may be secured to the curable medium 13 and/or the preformed trench. In a preferred embodiment, the installation legs 28 may be L-shaped such that the installation leg 28 is divided into a short portion and a long portion, where the short portion is perpendicularly attached to the long portion. The short portion of the installation leg 28 may comprise a hole through which fastening elements may be inserted to secure the installation leg 28 to the trench and/or the curable medium 13. Said fastening elements may include screws, nuts, bolts, clips, pins, or the like. The long portion of the installation leg 28 may comprise a vertical adjustment slot through which an adjustable fastening element may be placed to adjustably attach the installation leg 28 to a sidewall 21 of the open-faced channel 15. The adjustable nature of the adjustable fastening element and vertical adjustment slot facilitate positioning the open-faced channel 15 at a desired height within the preformed trench and retaining that desired height when the curable medium 13 is poured around the open-faced channel 15.

(35) The open-faced channel 15 can be formed from any suitable material, such as a cementitious and/or thermosetting or thermoplastic polymeric material. For example, the open-faced channel 15 can be formed from a polymer/concrete aggregate material. More particularly, the open-faced channel 15 of one advantageous embodiment is formed from a thermosetting polymeric resin, such as acetone, and an aggregate material. The aggregate material is preferably a chemically inert material, such as silica or glacial till. In one embodiment, the open-faced channel 15 includes greater than about 85% by weight of aggregate.

(36) Referring now to FIGS. 1, 2A-2C, 3, 6, 7, and 8A-8B, the drainage system 14 may be configured to receive at least one structural member 30 and, preferably, a network of structural members 36. In some embodiments, the structural member 30 may be a reinforcing bar (referred to herein as rebar), and thus the network of structural members 36 may be a rebar network. Each structural member 30 has a first end 32 and second end 34 and is preferably formed of stainless steel, galvanized, or coated on the exterior with a water-resistant substance. In some embodiments, the first end 32 of a structural member 30 extends through an aperture 33 in at least one of the sidewalls 21 of the open-faced channel 15, while the second end 34 of the structural member 30 extends through an aperture 33 in at least a different one of the sidewalls 21 of the open-faced channel 15. In such embodiments, the apertures 33 matingly engage with the ends of the structural member. In a typical embodiment, a structural member 30 may extend through an aperture 33 in a first sidewall and extend through an aperture 33 in a second sidewall which is across from the first sidewall. For instance, a structural member 30 extending through an aperture 33 in the first lateral side 19 may extend through an aperture 33 in the second lateral side 20. Additionally or alternatively, a structural member 30 extending through an aperture 33 in the first end member 17 may extend through an aperture 33 in the second end member 18.

(37) The first and second ends 32, 34 of a structural member 30 are adapted to connect to the ends of structural members 30 of a structural support located within the sidewalls of the preformed trench and may be permanently or removably attached to the apertures 33 in the sidewalls 21 of the open-faced channel 15. By connecting the open-faced channel 15 to the structural members 36 within the trench sidewalls, the open-faced channel 15 may be secured in a more stable manner when compared to conventional methods. In some embodiments, one or more of the apertures 33 may be sealed by a sealing structure such as a grommet, gasket, bushing, or the like. Said sealing structures, which serve to help reduce and/or prevent fluid leakage near the apertures 33, may preferably be made of an elastic material such as rubber, but may also be made of plastic or metal.

(38) In some embodiments, a conduit connector 38 may be embedded within one of the sidewalls 21 or within the bottom wall 22 of the open-faced channel 15, as depicted in FIG. 2C and 8B. The conduit connector 38 can effectively connect a drainage system component, such as a conduit, which can serve as either an inlet or an outlet to the drainage system 14. Preferably, the conduit connector 38 is embedded within the bottom wall 22 of the open-faced channel 15 by being integrally molded within the material forming the open-faced channel 15 during casting. In some embodiments, the bottom wall 22 of the open-faced channel 15 may be angled downward toward the conduit connector 38 such that fluids may be channeled into the conduit connector 38 using gravity. In other embodiments, the bottom wall 22 may be substantially level.

(39) Additionally, as shown in FIGS. 2A-2C, 3-7, and 8A-8B, the drainage system 14 may also include a trench cover 42 that is preferably supported by a support surface 40 on the upper portion of the open-faced channel 15. In such embodiments, the support surface 40 may be created by a lateral and vertical extension of the top portions of the lateral sides 19, 20, as best seen in FIGS. 1, 2A, and 7. For instance, if the trench cover 42 is in the shape of a rectangular prism, the top portions of the lateral sides 19, 20 may extend laterally at a 90 degree angle from the side wall, then vertically at a 90 degree angle from the lateral extension in order to accommodate the rectangular trench cover 42. The trench cover 42 may be arranged in a lattice configuration (e.g., a grate, grille, mesh, or the like) to permit fluids to pass therethrough while providing resistance against downward forces, such as those caused by placing an object on the top portion of trench cover 42 (e.g., a vehicle tire, a person's foot, debris, or the like). The trench cover 42 can be made from a range of materials, such as metals, polymers, carbon fiber, and the like.

(40) As best shown in FIGS. 2B, 2C, and 4-7, the trench cover 42 preferably includes at least a first and second integrally-formed lug 46A, 46B. During installation of the trench cover 42 in the drainage system 14, the second integrally-formed lug 46B is slid under a stationary retention pin 26B that is fixed through a hole in one of the sidewalls 21 and then the first integrally-formed lug 46A is placed on the support surface 40. Next, a removable retention pin 26A is placed above the first integrally-formed lug 46A and through another hole in one of the sidewalls 21, such that a space is formed between the removable retention pin 26A and the first integrally-formed lug 46A. A removable plate 44 is then slid in the space between the removable retention pin 26A and the first integrally-formed lug 46A, creating an interference in the removal of the first integrally-formed lug 46A past the removable retention pin 26A and, in turn, facilitating retention of the trench cover 42 in the drainage system 14. The interaction between the second integrally-formed lug 46B and the stationary retention pin 26B also facilitates retention of the trench cover 42 in the drainage system 14. In some embodiments, the removable retention pin 26A and the stationary retention pin 26B each extend through a hole in one of the sidewalls 21 and interact with the curable medium 13 poured around the open-faced channel 15 to secure the open-faced channel 15 in the curable medium 13 and bear any retention weight applied to the trench cover 42.

(41) The length of the open-faced channel 15 may be extended as needed by increasing the length of the first and second lateral sides 19, 20. As best shown in FIGS. 8A and 8B, the trench cover 42, which may be a unitarily constructed piece or a combination of multiple separate trench cover pieces, may be secured to the lengthened open-faced channel 15 by alternating sets of stationary retention pins 26B and removable retention pins 26A to interface with the integrally formed lugs 46A, 46B of the trench cover 42. In this way, the open-faced channel 15 may be configured to retain trench covers 42 even when the open-faced channel 15 is lengthened.

(42) Referring now to FIGS. 9A-9G and 10A-10F, another embodiment of the present invention may provide a drainage system 14 comprising an open-faced channel 15 that is defined by a first and second ring member 51, 52 and a collection member 53. Each of the first and second ring members 51, 52 may comprise a pair of end members and a pair of lateral side members that can be formed integrally together or formed separately and then welded together or secured together using mechanical fasteners. Each of the first and second ring members 51, 52 may be formed such that the pair of end members and pair of lateral side members define an inner perimeter dimensioned such that the sidewalls 21 of the collection member 53 fit within the inner perimeters of the first and second ring members 51, 52. Typically, the first ring member 51 is positioned above the second ring member 52 such that when the collection member 53 is lowered into the ring members 51, 52, each ring member 51, 52 wraps fully around the collection member 53.

(43) The collection member 53 may comprise first and second lateral sides 19, 20 and first and second end members 17, 18, which together will be referred to herein as the sidewalls 21 of the collection member 53. In a preferred embodiment, the sidewalls 21 are connected to one another in a substantially perpendicular manner at their edges to form a substantially rectangular shape. The collection member 53 may further comprise a bottom wall 22, which may be connected at the edges to the sidewalls 21 of the collection member 53 to create a floor portion of the open-faced channel 15. In this way, the sidewalls 21 and the bottom wall 22 of the collection member 53 are combined to define an interior cavity of the open-faced channel 15. In some embodiments, the sidewalls 21 and bottom wall 22 of the collection member 53 may be a part of a unitary construction. In other embodiments, the sidewalls 21 and bottom wall 22 may be individual parts that are affixed together by welding, adjustable fasteners, or the like. The bottom wall 22 may comprise a conduit connector 38 to facilitate the removal of fluids from the open-faced channel 15.

(44) Each of the first and second ring members 51, 52 are preferably constructed using a highly durable and rust-resistant material, such as stainless steel, galvanized or coated steel, or the like. On the other hand, the collection member 53 may be constructed of cementitious and/or polymeric materials, metals, or the like. In this way, the open-faced channel 15 confers the benefit of high structural rigidity and stability provided by the strong first and second ring members 51, 52 while reducing manufacturing and/or replacement costs with respect to the collection member 53.

(45) The collection member 53 may further be removably coupled to the first and second ring members 51, 52 when the drainage system 14 is installed into a trench. In this regard, the first and second ring members 51, 52 may each comprise one or more reinforced apertures 51A, 51B located along the perimeter of the first and second ring members 51, 52. Said apertures 51A, 51B may take the form of a cylindrical opening which is oriented perpendicularly to the first and second ring members 51, 52 in a horizontal manner; in other words, the apertures 51A, 51B provide a lateral passageway through which a structural member 30 (e.g., rebar) may pass.

(46) The sidewalls 21 of the collection member 53 may also comprise one or more apertures 33 through which a structural member may pass. The apertures 33 of the collection member 53 may be cylindrical openings which run perpendicularly to the sidewalls 21 of the collection member 53 in a lateral fashion. In particular, the collection member 53 may comprise a first set of apertures 33A around the perimeter of the sidewalls 21 of the collection member 53. The first set of apertures 33A may correspond to the apertures 51A of the first ring member 51 such that the apertures 51A of the first ring member 51 and the first set of apertures 33A of the sidewalls 21 of the collection member 53 may be aligned, as best shown by comparing FIG. 9D with the cutaway view as seen in FIG. 9E, or by comparing FIG. 10D with the cutaway view as seen in FIG. 10E. Accordingly, the apertures 51A of the first ring member 51 and the apertures 33 of the collection member 53 are preferably formed in the same size and shape as one another, and are typically dimensioned to allow a structural member 30 to pass therethrough. In this way, the first ends 32 of a first set of structural members 30 may pass through both the apertures 51A of the first ring member 51 and the first set of apertures 33A of the collection member 53. Once the structural members 30 have passed through the first ring member 51 and the collection member 53, the first end 32 of the structural members 30 may be affixed to the open-faced channel 15. The second end 34 of the structural members 30 may then be secured to the structural members within the sidewalls of the trench, thereby securing the open-faced channel 15 to the trench and/or curable medium 13.

(47) The collection member 53 may further comprise a second set of apertures 33B around the perimeter of the sidewalls 21 of the collection member 53 which correspond to the apertures 52A of the second ring member 52 such that the apertures 52A of the second ring member 52 and the second set of apertures 33B of the collection member 53 may be aligned. In this way, the first ends 32 of a second set of structural members 30 may pass through both the apertures 52A of the second ring member 52 and the second set of apertures 33B of the collection member 53 such that the second ring member 52, the collection member 53, and the first ends 32 of the structural members 30 may be affixed to one another. The second ends 34 of said structural members 30 may then be affixed to the structural members 30 within the sidewall of the trench. In this way, the collection member 53 may be secured by an evenly distributed array of structural members 30.

(48) In some embodiments, the first ring member 51 may additionally provide a support surface 40 for installing a trench cover 42, as best seen in FIGS. 9A, 9F, 9G, 10A, and 10F. Said support surface 40 may be formed by creating a lateral extension of the top portion of the first ring member 51, then creating a vertical extension from the lateral extension such that a rectangular recess is formed by the top portion of the first ring member 51. In this way, the rectangular recess forms a seat and/or frame that is dimensioned to accept a trench cover 42.

(49) As best shown in FIGS. 9A-9G, in some embodiments, the reinforced apertures 51A of the first ring member 51 may be positioned in an offset manner in relation to the reinforced apertures 52A of the second ring member 52, such that the reinforced apertures 51A, 52A of the first and second ring members 51, 52 are placed in a staggered configuration. In such a configuration, the apertures 51A of the first ring member 51 are not vertically aligned with the apertures 52A of the second ring member 52. In this way, when the structural members 30 are inserted into the first and second ring members 51, 52 and the collection member 53, the potential load on the drainage system 14 may be more evenly distributed.

(50) As best shown in FIGS. 10A-10F, in other embodiments, the apertures 51A, 52A of the first and second ring members 51, 52 may be positioned in a stacked configuration such that the apertures 51A of the first ring member 51 are vertically aligned with the apertures 52A of the second ring member 52. Such a configuration may be seen when the first and second ring members 51, 52 have identical structures, as best seen in FIGS. 10C and 10D. In this way, the cost of manufacturing the first and second ring members 51, 52 may be reduced.

(51) Referring now to FIGS. 11A-11D, another embodiment of the present invention may provide a drainage system 14 comprising an open-faced channel 15 formed from first and second lateral sides 19, 20 and first and second end members 17, 18 which collectively make up the sidewalls 21 of the open-faced channel 15. The open-faced channel 15 may further comprise a bottom wall 22 which may in turn comprise a conduit connector 38 or drainage port configured to receive a drainage pipe. The bottom wall 22 may be coupled with the sidewalls 21 in a substantially perpendicular manner to define the open-faced channel 15 to substantially resemble an open-topped rectangular prism. In some embodiments, the bottom wall 22 is coupled to the sidewalls 21 such that the bottom wall 22 is substantially level. In such embodiments, the top edges and bottom edges of the sidewalls 21 may be substantially parallel to each other.

(52) As best seen in FIG. 11D, in other embodiments, the bottom wall 22 may be angled in the direction of the conduit connector 38 to facilitate the drainage of fluids entering the open-faced channel 15. In such embodiments, the top edges of the first and second lateral sides 19, 20 may be substantially level while the bottom edges of the first and second lateral sides 19, 20 may be slanted at an angle in the direction of the conduit connector 38. In addition, the height of the first end member 17 may be longer than the height of the second end member 18, or vice versa, according to the direction in which the bottom wall 22 and the bottom edges of the first and second lateral sides 19, 20 are angled.

(53) The sidewalls 21 of the open-faced channel 15 may comprise one or more reinforced apertures 33 distributed laterally around the perimeter of the sidewalls 21 the open-faced channel 15. Each reinforced aperture 33 may be located in the body of the sidewalls 21 and take the form of a cylindrical opening which is oriented perpendicularly to the sidewalls 21. In this way, the reinforced apertures 33 are configured to receive structural members 30 (e.g., rebar) into the interior of the open-faced channel 15. Once the first ends 32 of the structural members 30 have been inserted into the reinforced apertures 33, the first ends 32 of the structural members 30 may be secured to the sidewalls 21, and the second ends 34 of the structural members 30 may be secured to the structural members and/or structural member network 36 within the sidewall of the trench. In some embodiments, as best seen in FIGS. 11A, 11C, and 11D, the reinforced apertures 33 may further comprise pipe-to-pipe sleeves which may extend outward laterally from the outer surfaces of the sidewalls 21 of the open-faced channel 15, which may further assist in securing the structural members 30 to the open-faced channel 15. In addition, the reinforced apertures 33 may comprise a sealing member such as a gasket, grommet, or the like, in order to prevent the leakage of fluids outside of the open-faced channel 15.

(54) In some embodiments, the open-faced channel 15 may be configured to accept a trench cover 42 to prevent foreign objects (e.g., non-liquid matter such as leaves, garbage, or the like) from entering open-faced channel. In such embodiments, the top portions of the first and second lateral sides 19, 20 may comprise an outward lateral extension from the top edges of the first and second lateral sides 19, 20 and an upward vertical extension from the edges of the outward lateral extension, as best seen in FIG. 11A. In this way, the extensions may create a support surface 40 upon which a trench cover 42 may be placed.

(55) In some embodiments, the open-faced channel 15 may further comprise one or more coupling members 60 that may be located proximate to the top portions of the sidewalls 21. Each coupling member 60 may comprise an anchor portion 60A combined with a hollow portion 60B, where the hollow portion 60B may be affixed to the anchor portion 60A at a 45-degree angle. In a preferred embodiment, the coupling members 60 may be inserted upward and diagonally (e.g., at a 45-degree angle upward from parallel) into openings (e.g., holes 62) located near the top of the first and second lateral sides 19, 20, such that the anchor portion 60A is oriented vertically from parallel and the hollow portion 60B is oriented upwards and diagonally into the open-faced channel 15. For instance, as seen in FIG. 11A, the coupling members 60 may be inserted diagonally upward into a hole 62 located along the corner created by the lateral extension and vertical extension of the first and second lateral sides 19, 20. The coupling members 60 may be then affixed to the first and second lateral sides 19, 20 such that when a curable medium 13 is poured to surround the open-faced channel 15 to a level that is above the coupling members 60, the open-faced channel 15 may be anchored to the curable medium 13 via the anchor portions 60A of the coupling members 60.

(56) In some embodiments, the hollow portions 60B of the coupling members 60 may be configured to receive a removable retaining pin 61. For instance, if the hollow portion 60B of the coupling member 60 is cylindrical, then the removable retaining pin 61 may be a cylinder dimensioned to fit within the interior of the hollow portion 60B of the coupling member 60. Once the removable pin 61 is inserted into the hollow portion 60B of the coupling member 60, the removable pin 61 may provide a mechanism by which to secure the open-faced channel 15 within the trench by resisting any upward movements of the open-faced channel 15. In embodiments in which the open-faced channel 15 comprises a trench cover 42, the removable pin 61 may be inserted after the trench cover 42 is placed onto the support surface 40 of the first and second lateral sides 19, 20. In such embodiments, the removable pin 61 may be positioned above an integrally-formed lug of the trench cover 42 such that the removable pin 61 resists the upward movement of the trench cover 42.
