DETAILED DESCRIPTION

[0030] Exemplary embodiments are described with reference to the accompanying drawings. In the figures, which are not necessarily drawn to scale, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. Also, the words “comprising,” “having,” “containing,” and “including,” and other similar forms are intended to be equivalent in meaning and are intended to be open ended such that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items or meant to be limited to only the listed item or items. It should also be noted that as used in the present disclosure and in the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise.

[0031] A solution may be provided by embodiments disclosed herein to the recognized need for improving the stability and placement of flared end ramps and improving the connection and fit between flared end ramps and inlet pipes. In particular, apparatuses and devices in accordance with embodiments of the present disclosure may enable flared end ramps to be securely fixed laterally and vertically within a stormwater chamber. Solutions are disclosed that improve the connection between flared end ramps and inlet pipes by easing access to fasteners and fastener locations that secure inlet pipes to flared end ramps.

[0032] In various embodiments, a flared end ramp apparatus may be provided that is constructed and arranged to attach to, or be placed within, a chamber useful for a chamber-type stormwater management system. In particular, the ramp may be constructed and arranged to attach to, or be placed within, an interior surface of an end cap of a chamber of a stormwater management system. In this configuration, fluid and solid materials may exit an interior of the chamber by traversing the ramp and passing through an exit defined by the end cap of the chamber. For example, the ramp may be left in place during use of the stormwater system and may be available for periodic cleaning.

[0033] The ramp apparatus may be configured to improve chamber function over time, and may have a shape, form, and profile that is non-obtrusive and does not frustrate chamber function. For example, the ramp apparatus may provide an inclined surface from a ground on which the chamber is positioned to an exit passage at an end of the chamber. The ramp apparatus may be shaped to guide fluid and debris through the exit and away from the portions of the chamber interior at which debris and sediment may typically collect in related art systems, such as at the end cap interior around the exit of the chamber. The ramp apparatus may include vertical tabs positioned on the edge of the outlet end of the ramp that correspond with the exterior of the stormwater chamber, which may secure the flared end ramp and prevent unwanted lateral or vertical movements of the ramp.

[0034] FIG. 1 depicts an embodiment of a flared end ramp 100. Flared end ramp 100 may be constructed of plastic (e.g., polypropylene, HDPE, LDPE, PVC), metal, and/or any other suitable material. Flared end ramp 100 may have an inlet end 105. Inlet end 105 may be configured to connect to an inlet pipe. Inlet end 105 of flared end ramp 100 may have a smaller width than outlet end 110. This configuration may enable flared end ramp 100 to prevent sediment in runoff from accumulating around the inlet end cap of a stormwater chamber by distributing the runoff (and the sediment contained therein) away from the chamber's inlet end and across the entire width of the chamber. Flared end ramp 100 may include at least one support foot 112 attached to a bottom portion of the ramp at or near outlet end 110. The at least one support foot 112 may extend laterally from flared end ramp 100 to form a wide structure configured to support the ramp. On an end of support foot 112, there may be a tab 120. Tab 120 may extend vertically upward relative to support foot 112.

[0035] In some embodiments, inlet end 105 may include a plurality of protrusions 115 on the upper side of the inlet end 105. Protrusions 115 may be separated by a gap in an initial state and may deflect to allow placement of an inlet pipe into inlet end 105.

[0036] Flared end ramp 100 may also include one or more drainage channels 125, which may be formed in the inclined surface to promote flow of runoff from inlet end 105 towards outlet end 110. For example, as depicted in FIG. 1, flared end ramp 100 may include a drainage channel 125 extending from near the center of the inclined surface at inlet end 105 laterally outward towards outlet end 110. Advantageously, in some embodiments, drainage channels 125 may promote runoff away from the center of the flared end ramp towards the sides of the flared end ramp, thereby dispersing fluid towards chamber side walls and away from the chamber center when the flared end ramp 100 is placed inside a stormwater chamber.

[0037] In some embodiments, flared end ramp 100 may include an indent 130 at or near inlet end 105, indent 130 being configured to prevent the pipe from sliding towards outlet end 110. Indent 130 may be rounded with a curvature corresponding to the radius of the inlet pipe where indent 130 protrudes upward from the upper side of inlet end 105 to a distance that is level with the inside diameter of the inlet pipe. Indent 130 may prevent an inlet pipe from sliding toward outlet end 110 by providing a stop for an inlet pipe to abut against when inserted into inlet end 105.

[0038] Flared end ramps may be constructed with inlet ends suitable for various different sizes of inlet pipes or stormwater chambers. For example, FIG. 2 depicts another embodiment of a flared end ramp that has a wider outlet end 110 than the flared end ramp shown in FIG. 1. One skilled in the art will appreciate that a variety of sizes of the inlet end or outlet end may be constructed for a variety of applications.

[0039] FIG. 3A depicts a close-up view of an embodiment of a flared end ramp outlet end 110. As is shown in FIG. 3A, a drainage channel 125 is formed by a pair of raised ridges on the flared end ramp 100. Fluid in drainage channel 125 may travel between the raised ridges between the inlet end 105 and the outlet end 110.

[0040] FIG. 3B depicts an embodiment of a support foot 112 with a tab 120. Tab 120 may extend vertically compared to support foot 112. In some embodiments, flared end ramp 100 may be placed inside a stormwater chamber and support foot 112 may extend underneath the chamber walls, with tab 120 positioned outside of the chamber. Such an arrangement provides several advantages. For example, the weight of the chamber and overlying material bears on the support foot 112, thereby securing the flared end ramp 100 to a ground surface and preventing the flared end ramp from rising up or becoming undermined with debris from cleaning operations. Tab 120 extends vertically upward and may abut the outside of the chamber wall, which prevents the flared end ramp 100 from shifting in a lateral direction.

[0041] FIG. 4 depicts a view of an embodiment of a flared end ramp viewed from a lower-right perspective. As shown in FIG. 4, indent 130 may function as a pipe stop in that the indent extends laterally inward from inlet end 105 and restrains a pipe from sliding toward outlet end 110. In an embodiment, indent 130 may be rounded with a curvature corresponding to the radius of an inlet pipe and indent 130 may protrude upward from the upper side of the inlet end to a distance that is level with the inside diameter of the pipe. Such an arrangement may align the invert of an inlet pipe with the edge of the indent 130 and may provide for free flow of fluid from the inlet pipe into the flared end ramp 100 and the chamber. Additionally, indent 130 may prevent catch points and allow for a smooth transition of a jet vac during maintenance operations.

[0042] FIG. 5 depicts an embodiment of inlet end 105 of a flared end ramp 100 that includes protrusions 115 on the upper side of the inlet end 105. There may be a gap between protrusions 115 which allows for the placement of an inlet pipe in the inlet end 105. In an embodiment, inlet end 105 may be flexible so as to allow tolerances for placement of an inlet pipe within the inlet end. In another embodiment, inlet end 105 and protrusions 115 are rigid and do not flex.

[0043] FIGS. 6A and 6B depict embodiments of a flared end ramp 100 connected to a pipe 610. Various types of fasteners may be used to connect protrusions 115. Connecting protrusions 115 with a fastener may secure the inlet pipe 610 to the flared end ramp 100. In the embodiment depicted in FIG. 6A, a threaded rod 605 type fastener is used. Threaded rod 605 may be secured and tightened with a nut, thereby pinching protrusions 115 together to secure inlet pipe 610 to flared end ramp 100. In the embodiment depicted in FIG. 6B, zip ties are used as a fastener to tighten protrusions 115 to secure inlet pipe 610 to the flared end ramp 100. In other embodiments, various other forms of fasteners may be used such as bolts, screws, studs, clamps, or rivets. In other embodiments, adhesives, cements, or various solvent welding techniques may be used to secure protrusions 115 or may be applied to inlet pipe 610 to secure it to flared end ramp 100.

[0044] FIG. 7 depicts an embodiment of a flared end ramp 100 connected to a pipe 610 that is inserted into a stormwater chamber 700. Flared end ramp 100 may span the width of chamber 700, and tabs 120 may extend outside the external walls of chamber 700 as described above. In an embodiment, stormwater chamber 700 may rest on support foot 112 of flared end ramp 100, securing the flared end ramp 100 to the ground surface with the weight of the chamber 700. Tabs 120 may freely extend outside of the chamber to prevent lateral movement of the flared end ramp 100. In other embodiments, tabs 120 may attach to chamber 700. For example, tabs 120 may be secured to the chamber 700 with fasteners, welds, or clamps. Alternatively, tabs 120 may be configured to interlock mechanically with a receptacle positioned on the outside of chamber 700, for example, a snap-style connection wherein tab 120 acts as a hook to a counterpart receptacle on the chamber 700.
