Technical Field

[0001 ] The present disclosure relates to an infrastructure pit, also known as a junction pit or a vault, for infrastructure assets, such as water or gas pipelines, electrical conduits, telecommunications and/or optical fibre conduits, which are typically located in-ground for the purpose of providing infrastructure services for buildings, whether for residential or commercial properties.

[0002] More particularly, the present disclosure concerns an infrastructure pit or vault or a junction pit or vault comprising a body, preferably of moulded plastic, that forms a housing or an enclosure for the infrastructure assets, which body is configured to be set in the ground and form an access point for technicians to access the in-ground infrastructure lines, cables, or conduits. It will be convenient to describe the disclosure herein in this exemplary context. It should be understood, however, that the disclosure is not limited to junction pits or infrastructure pits and may be used in other applications and contexts.

Background Art

[0003] Any reference to or discussion of background art, including to any documents, herein is intended to facilitate an understanding of the present disclosure only and is not to be considered as an admission that such background art forms part of the state of the art or is widely known or forms a part of the common general knowledge in the relevant field in Australia or in any other country at the date of this application.

[0004] Infrastructure pits, or junction pits, or vaults for infrastructure assets have been known in various forms for many years. As noted above, they provide an access point for technicians to access the in-ground infrastructure lines, cables, or conduits. The access may be required, for example, to make a new connection to one or more of those assets, for maintenance, and/or for repair purposes. The dimensions of the pits or vaults can vary depending on a particular application, but it is not unusual that they will be sufficiently large for a worker to stand inside the pit I vault when accessing the infrastructure lines, cables, or conduits. For many decades these pits or vaults have been fabricated as cast concrete components which, while durable, are naturally also quite heavy and therefore laborious to transport or to handle manually, as well as being susceptible to cracking or breakage if dropped prior to installation. In more recent years, lighter-weight variants made of polymer plastic material have become available and have gained popularity due to much greater ease of transport and handling with good performance in use. It nevertheless remains a goal to optimise a physical design of the infrastructure pits or vaults, their performance in use, their ease of assembly, their adaptability to differing installation conditions, as well as the material usage and cost in their fabrication.

Summary

[0005] In view of the above, it would be desirable to provide a new infrastructure pit I vault or a new junction pit I vault for accommodating infrastructure assets, such as water pipelines, gas lines, electrical conduits, telecommunications lines, or optical fibre conduits, or other assets that require infrastructure pits or vaults.

[0006] According to a broad aspect, the present disclosure provides an infrastructure pit or junction pit for accommodating in-ground infrastructure assets, such as water lines, gas lines, electrical cables, telecommunications lines, and/or optical fibre conduits. The infrastructure pit I junction pit comprises: a moulded plastic body having a base, and walls upstanding from the base, e.g., side walls and end walls, that together define a cavity for housing the infrastructure assets. The moulded plastic body is configured to receive one or more reinforcing members removably inserted in and/or along the walls. A rim member (also referred to as a “collar”) is configured to be attached to a top edge of the walls (e.g., the side walls and end walls) of the moulded plastic body to define a perimeter of an access opening into the infrastructure pit or junction pit, and at least one cover member is adapted to seat against the rim member for covering the access opening into the pit.

[0007] In this way, the infrastructure pit or junction pit or vault of this disclosure is able to be selectively modified or strengthened by (removably) inserting one or more reinforcing member, e.g., an elongate reinforcing member or rib member, into and/or along walls of the pit or vault. This provides flexibility of design in enabling selective reinforcement in the applications where that may be required without over-designing the infrastructure pit or junction pit or vault for those other applications in which reinforcement may not be required. This, in turn, optimises the use of materials I resources, reducing waste and also cost.

[0008] In an embodiment, the walls of the body (e.g., side walls) include a plurality of apertures for receiving or mounting one or more reinforcing member (e.g., rib member) therein. The apertures are preferably configured for receiving or mounting the reinforcing member(s) in and/or along the walls such that the reinforcing member(s) extend/s in a generally horizontal orientation. Each reinforcing member preferably comprises a straight rod or bar, which may have any desired cross-sectional configuration, such as round, flattened, or some other shape. By having a plurality of apertures spaced over the height of the walls, a user can select the desired degree or extent of the reinforcement required by a particular application and the location in the wall. Each of the reinforcing members may, for example, be comprised of a fibre reinforced polymer composite material, such as glass-fibre reinforced polymer (GRFP), which has good strength, low weight, and relatively low cost. However, a range of other materials, such as other composites, polymer resins, or metals like steel, cast iron, or aluminium could also be used.

[0009] In an embodiment, the side walls of the moulded plastic body are formed with substantially vertically extending indentations therein to enhance rigidity and dimensional stability of the body. In such a case, the apertures for receiving and/or mounting the one or more reinforcing members or rib members may be formed or provided in the vertically extending indentations. This provides a convenient location for setting or mounting the reinforcing members or rib members. In this way, the reinforcing members may be set or mounted in the walls such that they do not project laterally outwards of the walls.

[0010] In an embodiment, the junction pit further includes one or more cable hangers configured to be arranged within the moulded plastic body and to extend between opposite walls thereof. The cable hanger(s) operate/s to support the infrastructure lines or conduits suspended therefrom in the pit or vault. Ends of each cable hanger are preferably adapted to engage with respective reinforcing members inserted along the walls of the body. In this way, the cable hanger(s) can be supported on and registered or located with respect to the reinforcing members. Further, the cable hanger(s) may be repositionable or adjustable in position within the moulded plastic body depending on the particular application. Each cable hanger may be provided in the form of a rod or tube, which can provide transverse reinforcement or support to walls of the pit or vault as strut members. The cable hangers are preferably comprised of a polymer resin, such as PVC, and may be extruded, but other materials, such as composites, other polymer resins, and metals are also contemplated.

[0011 ] In an embodiment, the rim member presents an inward recessed shoulder or step forming a seat around the perimeter of the access opening, wherein the at least one cover member seats against the recessed shoulder or step in the rim member such that an upper surface of the cover member lies substantially flush with an upper edge of the rim member. The recessed shoulder or step forming the seat around the perimeter of the access opening preferably provides a form fit for the cover member(s) with a slight gap to avoid an interference fit or jamming. It will be appreciated that the cover member(s) will be sized or fitted to the rim member to approved tolerances to optimise the fit, because while an interference fit or jamming is undesirable, a larger gap (e.g., > 5mm) that could catch a narrow heel of a shoe or present a tripping hazard is also undesirable.

[0012] In an embodiment, the rim member is configured to seat against a flange at the top edge of the upstanding walls (e.g., side walls and end walls) of the moulded plastic body. The rim member is further configured to be attached to the top edge of the walls of the moulded plastic body by fasteners, e.g., by screws. In this way, the fasteners may pass through and engage with the flange at the top edge of the upstanding walls.

[0013] In an embodiment, a height position and/or an angular orientation of the rim member with respect to the top edge of the side walls and/or with respect to the top edge of the end walls is adjustable to cater for variation in installation conditions. That is, a height position of the rim member may be adjusted up from the top edge of the walls by a predetermined distance, e.g., at least up to about 10 mm, preferably at least up to about 20 mm, and more preferably at least up to about 30 mm, to accommodate installation conditions, e.g., the depth of a hole in which the pit is to be installed relative to the upper ground surface. Similarly, the angular orientation or pitch of the rim member can be adjusted with respect to the top edge of the upstanding walls to cater to different slopes of the upper ground surface during installation. The angular orientation or pitch of the rim member relative to the top edge of the walls may be adjusted by at least about 1 degree, preferably by at least up to about 2 degrees, and more preferably by at least up to about 5 degrees.

[0014] In an embodiment, the rim member is formed from a different, and preferably more rigid, material to the moulded plastic body, such as a plastic resin, resin composite, galvanised steel, aluminium, or concrete. In this way, the rim member (or collar) allows for particular material selection to match the particular environment. For example, high-risk environments for the pit, such as high fire risk zones, or high-volume traffic areas, or high mechanical load areas, may require the material of the rim member (collar) to be selected to meet those specific demands. The same considerations apply for the at least one cover member which is/are exposed to the above-ground environment. The rim member may be formed as a unitary moulded plastic component, desirably by injection moulding, to provide high dimensional reliability. An advantage of the configuration or design of the pit or vault of the present disclosure is that the rim member or collar is separately replaceable without the need to extricate and replace the body of the pit or vault. In this way, the parts of the pit or vault most susceptible to wear and damage from external influence, namely the rim member (or collar) and the cover or lid member(s), can be separated from the body and replaced relatively quickly and easily, as and when may be necessary.

[0015] In an embodiment, the moulded plastic body is a unitary or integral body. The base of the body is substantially flat and rectangular, and the upstanding walls comprise opposite side walls and opposite end walls, which preferably extend generally vertically upwards from the base of the body. The moulded plastic body is preferably roto-moulded which readily enables layered moulding and the use of post-consumer recycled (PCR) plastic material or “recyclate” in the body. The roto-moulding provides a body with more working area for the infrastructure assets and provides walls for easier cable and pipe penetrations for accommodating the assets. It will be appreciated that the moulded plastic body may also be formed in other moulding processes, such as injection moulding, and is not limited to rotational moulding (i.e., roto-moulding).

[0016] In an embodiment, the unitary moulded plastic body may include a predefined removable section formed in the upstanding walls thereof (e.g., side walls and end walls) which is adapted, when removed, to reduce a height or a depth of the junction pit by a predefined amount. In this regard, the removable section may be predefined by marks (e.g., lines) formed in the walls of the body, at or along which marks the section is to be cut or severed from the moulded plastic body.

[0017] According to another aspect, the present disclosure provides an infrastructure pit or vault for accommodating in-ground infrastructure assets, such as water lines, gas lines, electrical cables, telecommunications or optical fibre conduits The infrastructure pit or vault comprises: a unitary moulded plastic body comprising a base, and side walls and end walls upstanding from the base, which walls together with the base define a cavity for housing the in-ground infrastructure assets; a collar configured to be attached to a top edge of the side walls and end walls of the body to form a perimeter of an access opening into the infrastructure pit or vault, the collar having an inwardly recessed shoulder or step forming a seat around the perimeter of the access opening; and at least one lid member configured to seat against the recessed shoulder or step within the collar for covering the access opening into the pit, wherein, when the at least one lid member is seated against the recessed shoulder or step in the collar, an upper surface of the lid member lies substantially flush with an upper edge of the collar.

[0018] In an embodiment of the disclosure, the recessed shoulder or step forming the seat around the perimeter of the access opening provides a form fit for the lid member(s) with a slight gap to avoid an interference fit or jamming. In this way, the infrastructure pit combines reliable and releasable lid engagement with dimensional stability. As noted above, the gap is sized to approved tolerances or specifications to optimise the fit (e.g., in a range of 1 mm to 5 mm).

[0019] As noted above, in an embodiment of the disclosure, the collar is formed of a different, and preferably more rigid, material to the unitary moulded plastic body, such as a relatively hard polymer resin, resin composite, galvanised steel, aluminium or concrete. The same applies for the lid member(s). In this way, the collar and the lid member(s) of the pit, which are usually directly exposed to the above-ground environment, may be tailored to specific demands of the environment in which the pit is installed. For example, the collar may be a unitary moulded component formed from a tough, high-strength plastic resin material. Further, these parts of the pit or vault (i.e. , the collar and lid member(s)) are preferably separately replaceable without the need to rehabilitate the entire pit in the event that either or both should become damaged.

[0020] In an embodiment, the collar is configured to seat against a flange at the top edge of the side walls and end walls of the unitary moulded plastic body. In addition, the collar may be configured to be attached to the top edge of the side walls and end walls of the unitary moulded plastic body by fasteners, e.g., by screws. Further, a height position of the collar and/or an angular orientation of the collar with respect to the top edge of the side walls and/or with respect to the end walls may be adjustable to cater for variations in the installation conditions.

[0021 ] According to a further aspect, the present disclosure provides a junction pit or vault for accommodating in-ground infrastructure assets, such as water lines, gas lines, electrical cables, telecommunication lines, or optical fibre conduits, the junction pit or vault comprising: a unitary moulded plastic body comprising a base and walls upstanding from the base that together define a cavity for housing the infrastructure assets, a rim member configured to be attached at a top edge of the walls of the moulded plastic body to define a perimeter of an access opening into the junction pit, and at least one cover configured to seat against the rim member for covering the access opening into the junction pit. The unitary moulded plastic body includes a predefined removable section formed in the upstanding walls thereof such that, when removed, is designed to reduce a height or a depth of the junction pit or vault by a predefined amount.

[0022] In an embodiment, the removable section is predefined by marks (e.g., lines) formed in the walls of the body at which the removable section is configured to be cut or severed from the moulded plastic body.

[0023] According to yet another aspect, the present disclosure provides a junction pit or infrastructure pit for accommodating infrastructure assets, such as water lines, gas lines, electrical cables, telecommunication lines, or optical fibre conduits, the infrastructure pit or junction pit comprising: a moulded plastic body comprising a base and walls upstanding from the base that together define a cavity for housing the infrastructure assets, a rim member or collar configured to be attached at a top edge of the upstanding walls of the moulded plastic body to define a perimeter of an access opening into the junction or infrastructure pit, wherein an angular orientation and/or a height position of the rim member or collar is adjustable with respect to the top edge of the upstanding walls of the body to cater to ground level, and at least one cover adapted to seat against the rim member for covering the access opening into the junction pit or infrastructure pit.

[0024] Some advantages provided by embodiments of the infrastructure pit I vault or junction pit I vault of the present disclosure may include the following: (i) extremely tough and durable; (ii) low weight, providing ease of handling and ease of installation (iii) low cost and low carbon footprint; (iv) retrofittable to existing infrastructure access points; (v) a damaged collar or rim member can be replaced without complete replacement of the pit or vault (vi) can utilise recycled materials and is itself recyclable at end of life; (vii) multiple sizes available, and (viii) complies with current specifications for pits.

[0026] The accompanying drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification. The drawings illustrate particular embodiments and together with the description serve to explain the principles of the invention. Other embodiments and many of the attendant advantages will be readily appreciated as they become better understood with reference to the following detailed description.

[0027] It will be appreciated that common and/or well understood elements that may be useful or necessary in a commercially feasible embodiment are not necessarily depicted in order to facilitate a more abstracted view of the embodiments. The elements of the drawings are not necessarily illustrated to scale relative to each other. It will also be understood that certain actions and/or steps in an embodiment of a method may be described or depicted in a particular order of occurrences while those skilled in the art will understand that such specificity with respect to sequence is not actually required.

Detailed Description Of The Embodiments

[0028] With reference firstly to Figs. 1 to 8 of the drawings, an infrastructure pit 1 (also referred to as a “vault” or an “infrastructure vault” or a “junction pit”) according to a preferred embodiment of the disclosure will be described. The infrastructure pit or vault 1 is designed to accommodate in-ground infrastructure assets (indicated by the pipe C shown in Fig. 6), such as water lines, gas lines, electrical cables, optical fibre conduits and the like, which are located in-ground to provide building services to residential and commercial properties. The infrastructure pit or vault 1 is designed to provide an access point for technicians to access the in-ground infrastructure lines, cables, or conduits. The access may be required, for example, to make a new connection to one or more of those assets, for maintenance, and/or for repair purposes. The dimensions of the pit or vault 1 can vary depending on a particular application, but it is not unusual that it will be sufficiently large for a worker to stand inside it when accessing the infrastructure lines, cables, or conduits. Accordingly, by way of example, a height or depth dimension may be in the range of 500 mm to 1 ,500 mm, a length dimension may be in the range of 500 mm to 2,000 mm, and a width dimension may be in the range of 300 mm to 800 mm.

[0029] The infrastructure pit or vault 1 comprises a unitary (i.e., one-piece) moulded plastic body 10 that is shown in isolation in Fig. 8 of the drawings. The plastic body 10 has a generally rectangular base 11 with a pair of opposite side walls 12 and a pair of opposite end walls 13 upstanding from the base and integrally formed with the base 11. The base 11 and those walls 12, 13 together define a cavity 14 for housing or accommodating the infrastructure assets. The side walls 12 of the plastic body 10 in this embodiment are formed with rows of apertures 15, provided as slots or holes, that are configured to receive elongate reinforcing members or rib members 16 which can be removably inserted into a row of aligned holes or slots 15 along the side walls 12 in a generally horizontal orientation, i.e., generally parallel to the base 11. By having rows of the apertures 15 spaced apart over the height of the side walls 12, a user can select the degree or extent of reinforcement and its location as required by a particular application for the pit or vault 1 . The reinforcing members or rib members 16 in this embodiment are generally flattened rods or bars and are comprised of a fibre reinforced polymer composite material, such as GRFP, which has good strength, low weight, and relatively low cost. In this example, three rib members 16 are provided spaced apart along each side wall 12.

[0030] As can be seen in drawing Figs. 1 and 2, the side walls 12 of the moulded plastic body 10 are formed with three substantially vertically extending indentations 17 to enhance the rigidity and dimensional stability of those walls 12. The rows of the holes or slots 15 for receiving or mounting the ribs or rib members 16 are formed in the vertically extending indentations 17, which provide a convenient location for setting or mounting the reinforcing ribs 16. In this position, the ribs 16 do not project laterally out beyond an outer surface of the side walls 12, but rather are predominantly located inside cavity 14. [0031 ] With reference to Figs. 4 and Fig. 5 of the drawings, it will be seen that the infrastructure pit 1 further includes a pair of short, straight cable hangers 18 configured to be arranged within the cavity 14 of the moulded plastic body 10 extending between the opposite side walls 12. Ends of each cable hanger 18 include slots 19 adapted to receive or engage with respective rib members 16 inserted along the side walls 12. In this way, the cable hangers 18 can be registered or located with respect to the rib members 16 for supporting lines or conduits in the pit or vault 1 suspended therefrom. In addition, each cable hanger 18 can provide transverse reinforcement or support to the side walls 12 of the pit or vault 1 as strut members. In this example, the cable hangers 18 are comprised of a polymer resin, such as PVC, and are moulded or extruded as tubes or rods. As the structural demands of the cable hangers 18 are relatively low, the polymer resin material generally provides adequate strength, combined with low weight and low cost, but other materials, such as composites, other polymer resins, and metals can also be used.

[0032] With continued reference to Figs. 1 to 8 of the drawings, the infrastructure pit 1 includes a collar or rim member 30 that is configured to be attached to a top edge 20 of the side walls 12 and end walls 13 of the moulded plastic body 10 to define a perimeter of an access opening 31 into the pit 1. The collar or rim member 30 in this embodiment is formed from a different, and more rigid, material to the moulded plastic body 10. While it could be formed of steel or concrete, in this case the collar 30 is injection moulded from a high-strength polymer resin for a high load-bearing capacity. The collar 30 presents an inward recessed shoulder or step 32 forming a seat around the perimeter of the access opening 31 . As can be seen in Fig. 6 and Fig. 7 of the drawings, two cover members or lid members 40 are configured to seat against the recessed shoulder or step 32 in the collar 30 such that an upper surface 41 of the cover members 40 lies substantially flush with an upper edge 33 of the rim member 30. The recessed shoulder or step 32 forming the seat around the perimeter of the access opening 31 is sized to provides a neat form-fit for the two cover members or lid members 40 with a slight gap to a desired tolerance to avoid an interference fit or jamming. As seen in drawing Fig. 5, the collar or rim member 30 is configured to seat against a flange 21 at the top edge 20 of the side and end walls 12, 13 of the plastic body 10. Further, the collar 30 is configured to be attached to that flange 21 along the top edge 20 of the side and end walls 12, 13 by screw fasteners 34. In this way, the screw fasteners 34 pass through and engage with the flange 21 at the top edge 20 of the walls. [0033] With reference now to drawing Figs. 8 to 11 , it will be seen that the moulded plastic body 10 of the infrastructure pit 1 includes a predefined removable section 22 that is formed in the upstanding side walls 12 and end walls 13. This removable section 22 is predefined by marks 23 in the form of score lines formed in the walls 12, 13 of the body 10 to demarcate a section of constant height or depth. By cutting or severing along these lines 23, the section 22 can be cut or severed from the moulded plastic body 10 so that, when removed, a height or a depth of the pit 1 is then reduced by a predefined amount (i.e. , corresponding to the height or depth of the section 22). In this regard, after removal of the section 22, the base 11 and remaining walls 12, 13 body are recombined in order to reconstitute the moulded plastic body 10, as shown in Fig. 10. To this end, as seen in Fig. 11 , connector plates 25 and fasteners (e.g., screw fasteners or an adhesive, such as a contact adhesive) may be used to reconnect the base 11 and shortened walls 12, 13.

[0034] Referring now to Figs. 12 to 14 of the drawings, a height position h and/or an angular orientation a, [3 of the collar or rim member 30 with respect to the top edge 20 of the side walls 12 and/or with respect to the top edge 20 of the end walls 13 is adjustable to cater for variation in installation conditions. That is, a height position h of the collar 30 may be adjusted up from the top edge 20 of the walls 12, 13 by a predetermined distance h of 25 mm to accommodate installation conditions, e.g., varying depth of a hole in the ground in which the pit 1 is installed relative to the upper ground surface (Fig. 12). Similarly, the angular orientation or pitch a, [3 of the collar 30 can be adjusted with respect to the top edge 20 of the walls 12, 13 to cater to different slopes of the ground surface during installation. The angular orientation or pitch a of the collar 30 relative to the top edge 20 of the end walls 13 may be adjusted by about 2.5 degrees (Fig. 13), The angular orientation or pitch [3 of the collar 30 relative to the top edge 20 of the side walls 13 may be adjusted by about 1 degree (Fig. 14).

[0035] Referring to Figs. 15 and 16 of the drawings, the infrastructure pit 1 is seen in an installed position set into the ground G with a layer of paving P surrounding the collar or rim member 30. The upper edge 32 of the rim member 30 is flush with or just below an upper surface of the paving P and the upper surface 41 of the lid members 40 lies flush with the upper edge 32 of the rim member 30.
