    FLOW CHANNEL FOR AN INSPECTION CHAMBER OR MAN-HOLE
    FIELD [0001] The present invention relates to a flow channel for an inspection chamber or man-hole.
    [0002] Further, the present invention relates to a use of a flow channel.
    [0003] Yet further, the present invention relates to an inspection chamber or manhole.
    [0004] Furthermore, the present invention relates to a method of manufacturing a flow channel for an inspection chamber or man-hole.
    [0005] Additionally, the present invention relates to a computer readable memory.
    20185502 prh 01 -06- 2018
    BACKGROUND [0006] Inspection chambers or man-holes are known by means of which a person can have access to a sewer system, a storm water removal system, a system for processing or transporting liquids, and the like. The inspection chambers or man-holes are normally used for providing access to a flow channel for reasons of inspection, maintenance, cleaning, de-clogging, and the like. Said inspection chambers or man-holes are typically 20 buried into the ground, for example below the tarmac of a street or below a walkway.
    Conventional systems employed for handling sewage, storm drainage and the like employ vertically oriented inspection chambers or manholes of generally cylindrical shape which are positioned at juncture locations of diverse flow pipes or at positions where flow pipes change their orientation. The inspection chambers or man-holes typically include a cover 25 which can be manually removed in order to provide access to a respective inspection chamber or man-hole.
    [0007] Each inspection chamber or man-hole comprises at least two flow openings or sewage water openings, i.e. at least one inlet opening for inwardly flowing material and
    20185502 prh 01 -06- 2018 at least one outlet opening for outwardly flowing material. An inflow pipe is connected to each inlet opening and an outflow pipe is connected to each outlet opening.
    [0008] Of course, also more than two sewer pipes may be connected to the inspection chamber or man-hole. There may be a plurality of inlet openings and/or a 5 plurality of outlet openings comprised by the inspection chamber or man-hole. Inflow pipes frequently arrive at different elevations and are frequently of different sizes. Also outflow pipes frequently depart at different elevations and are frequently of different sizes.
    [0009] When building a sewer system or replacing an existing inspection chamber or man-hole by a new one, it is often not possible to use a standardized inspection chamber or 10 man-hole, because the dimensions of the pipes, the orientations of the pipes and the depths of the pipes in the ground differ on a case by case basis. Therefore, the flow channel within the inspection chamber or man-hole has typically to be adapted accordingly.
    [0010] Document US 4867411 A discloses a plurality of invert forming mold members which are bolted together and have their ends received in internal frames 15 provided at adjacent pipe openings in a manhole. The mold members are formed of relatively thick and heavy polyurethane and are of U-shaped cross-section. A mold supporting plate is provided in each of the internal mounting frames and has an opening configured to matingly receive the endmost mold component. The mold components are provided in a variety of linear lengths, angular curved configurations and elevation 20 changing members so that they can be associated to form inverts required for any particular manhole configuration. The assembly of mold members is strong and rigid and does not require any additional internal bracing. However, a substantial amount of U-shaped members has to be cut into a predetermined form prior to bolting the members together in order to form a flow channel. Therefore, forming of the flow channel requires a substantial 25 number of parts and is time consuming and labour intensive. Due to the high number of Ushaped profiles, there is further a risk that the flow channel will start to leak.
    [0011] Further, document US 2008/141445 A describes an inspection chamber having a plastic sleeve as well as a plastic base attached to the sleeve and provided with at least two openings to which a pipe can in each case be attached. The plastic base has a 30 flow profile which extends between the openings, and is made up of at least two separate base parts which, at the edges thereof facing towards each other, are fixedly attached to one another by means of a joining technique, such as gluing, welding and/or pop rivets.
    20185502 prh 01 -06- 2018 [0012] Furthermore, document US 2005/161088 A teaches a manhole base or liner for directing the flow of liquid from a manhole inlet opening positioned in one of a plurality of possible locations in a manhole side wall to a manhole outlet opening in the manhole side wall, and a manhole having the base or liner. The base or liner includes a 5 perimeter, an upper surface extending to the perimeter, and a liquid flow path formed in the upper surface. The liquid flow path has, in series, first and second flow path portions, the first flow path portion defined by a first bottom wall and a pair of spaced apart side by side guide walls extending upwardly from the bottom wall, the guide walls each having a guide wall inner end and a guide wall outer end, the outer ends being located at the 10 perimeter and being spaced apart a greater distance than the distance between the inner ends, the second flow path portion being defined by a second bottom wall, contiguous with the first bottom wall, and a pair of spaced apart side by side channel walls extending upwardly from the second bottom wall, each channel wall having an inner channel wall end and an outer channel wall end, the inner channel wall ends meeting the respective 15 guide wall inner ends, and the outer channel wall ends being located at the perimeter.
    [0013] Document EP 1174550 A2 discloses a base element for a manhole shaft. The lower section of a shaft, using prefabricated parts, has at least two channel segments assembled into an inner body with an outflow connection and at least one inflow connection. The inner body, with the component parts fitted together, is embedded into a 20 lower part body with its base and mantle, so that the inflow and outflow connections match up with the inflows and outflows at the lower body.
    [0014] Document WO 93/19258 Al teaches that a modular system forming an inspection chamber or manhole for a drainage system comprises a base portion, an insert portion adapted to lie at least partly upon said base and having one or more drainage 25 channels fabricated within it, a plurality of support segments of desired arc lengths, the insert portion being supported at its edges between the top of the support segments and a stack of shaft rings, wherein each piece is preformed and the structure is adapted to be assembled in situ and to be connected to the ends of drainage pipes.
    [0015] Document GB 1363302 A discloses that a manhole comprises an access 30 chamber of moulded plastics material with a closed bottom and inlet forming portions spaced around the lower end of the sides of the chamber and an invert-forming insert of moulded plastics material fitting in the bottom of the chamber and having at least one
    20185502 prh 01 -06- 2018 upwardly facing channel forming an invert between two of the inlet forming portions. Preferably the insert is a tight fit in the chamber bottom with its sides blocking off the unused inlets and is snapped past an inward projection just above the inlets. The insert may be either a closed body with a bottom or it may be an open shell reinforced by ribs at 5 locations not bearing invert channels. The inlet forming portions may be knock outs in the chamber wall, sealing being effected round a pipe-end inserted in a knocked out hole by means of a grommet or the ends of the outwardly projecting blind spigots may be pierced or cut off to provide access. The upper end of the chamber is formed as a socket to receive an extension piece with an outward flange for contacting a manhole cover. Additional 10 socketing extension pieces may be provided between the chamber and extension piece.
    Instead of the rectangular form shown, the chamber, extensions and insert may be of octagonal or circular cross-section and the chamber may serve simply as a former surrounded in use by low grade concrete or other settable filler or by a built-up structure.
    [0016] Document US 2007/053750 A describes an inspection chamber having a 15 plastic sleeve, a plastic base accommodated in the sleeve and at least two branches connected to the sleeve, which base has a flow profile that extends between the two branches. The base is made up of at least two separate base parts that are permanently fixed to one another at their edges facing one another, such as by welding, fusing, gluing and the like.
    [0017] Document JP 6026065 A discloses an invert block structure for a manhole.
    Two invert blocks having laterally symmetric shape, which are bisplit so as to be inserted into a manhole through the opening of the latter after completion of the manhole, are combined on a base plate in a shape block so as to form a water channel corresponding to inlet and outlet pipes of the shape block. JP 6146313 A teaches an invert block for a man25 hole and a driving channel formation method. JP 5287766 A describes further an invert manufacturing method of a sewage man-hole. According to the method, concrete is poured into a form consisting of male and female types to form an invert, and precasting the invert takes place at a plant other than a man-hole construction site.
    [0018] In view of the foregoing, it would be beneficial to provide a flow channel for 30 various types of inspection chambers or man-holes, wherein forming of the flow channel requires a low number of parts and is less time consuming and less labour intensive.

    EMBODIMENTS [0042] In this document, the term “flow channel” means a flow system through which material such as sewage water and storm drainage can flow. The channel is configured to be connected to at least one inlet pipe and at least one outlet pipe. The 20 channel is configured to be arranged within an inspection chamber or man-hole. The channel is open on one side to provide access to the channel.
    [0043] In this document, the term “inspection chamber” means a structure by means of which a person can have access to a flow channel positioned within said structure. The structure comprises a base, a perimeter wall, at least one inlet opening, at least one outlet 25 opening and an access opening. A flow channel is further arranged within the structure.
    The structure is dimensioned such that a person cannot completely enter the structure.
    [0044] In this document, the term “man-hole” means a structure by means of which a person can have access to a flow channel positioned within said structure. The structure
    20185502 prh 01 -06- 2018 comprises a base, a perimeter wall, at least one inlet opening, at least one outlet opening and an access opening. A flow channel is further arranged within the structure. The structure is dimensioned such that a person can completely enter the structure via the access opening. Entering through the access opening may, for example, take place using a 5 ladder.
    [0045] In FIGURE 1 a schematic perspective view of a flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 is shown within an inspection chamber 2. Such inspection chambers 2 of a sewage system are, for example, located at a distance of about 40 m - 50 m to each other. The inspection 10 chambers 2 are typically connected to each other by sewage pipes. In FIGURE 1, an inspection chamber 2 comprising a base 8 and a perimeter wall 9 is shown. The inspection chamber 2 further includes an inlet opening and an outlet opening in the perimeter wall 9.
    An inlet pipe 5 is coupled to the inspection chamber 2 on one side and an outlet pipe 7 is coupled to the inspection chamber 2 on an opposite side.
    [0046] Within the inspection chamber 2 a flow channel 1 is arranged. The flow channel 1 comprises an inlet 4 configured to be coupled to the inlet pipe 5. The flow channel further comprises an outlet 6 configured to be coupled to the outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by at least one bent plate 3. In FIGURE 1, the shown flow channel 1 is straight.
    [0047] A support frame 10 is arranged on the base 8 of the inspection chamber 2.
    The frame 10 is configured to support the at least one bent plate 3 forming the flow channel 1. When installing the plate 3, the plate 3 is bent into a form corresponding to the form of a part of the frame 10. In other words, the predefined form of the flow channel 1 is achieved by pressing the plate 3 against parts of the frame 10. The bent plate 3 may be at 25 least temporarily attached to the frame using attachment means, for example clips, in order to align the at least one plate 3 and the frame 10 for welding the plate 3 and the frame 10 together. The thickness of the at least one bent plate 3 is typically in the range between 3 mm and 30 mm, and thus it is possible to bend the at least one plate 3 manually. Typically, heating of the at least one plate 3 is not required in order to bend the plate into a predefined 30 form. The surface of the plate 3 forming the flow channel 1 is smooth, i.e. there are typically no corners, steps, bumps, and the like. The flow channel 1 is normally U-shaped.
    20185502 prh 01 -06- 2018 [0048] Extension plates 11 are further connected to the at least one bent plate 3. The extension plates 11 cover the frame 10 and prevent overflowing of material from the flow channel 1. The extension plates and the at least one bent plate 3 are welded together or the extension plates 11 are an integral part of the bent plate 3. Typically, the at least one bent 5 plate 3 and the extension plates 11 are of the same material, for example thermoplastic material, in particular a polyolefin material, such as polyethylene (PE) or polypropylene (PP). Other suitable thermoplastic materials include weldable thermoplastic materials, such as polystyrene (PS), acrylonitrile butadiene styrene (ABS), polyimide (PI) and polyamide (PA) or a thermoset material. The extension plates 11 are further fixedly attached to the 10 frame 10. Also the frame 10 may be of the same material as the at least one plate 3 and the extension plates 11. Thus, all parts forming the flow channel 1 can be welded together.
    [0049] After installation of the flow channel 1 within the inspection chamber 2 and coupling the flow channel 1 to inlet and outlet pipes 5, 7, material can flow through the inspection chamber 2 along the flow channel 1 as indicated by arrow A. The pipes 5, 7 are 15 typically welded to the flow channel 1.
    [0050] Of course, the flow channel 1 may also be located within a man-hole instead of the inspection chamber 2.
    [0051] In FIGURE 2 a schematic front view of a flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 20 comprises an inlet configured to be coupled to an inlet pipe. The flow channel further comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by a bent plate 3. In FIGURE 2, the shown flow channel 1 is straight.
    [0052] Extension plates 11 are connected to the bent plate 3. The angle between the 25 extension plates 11 and the basis 8 may vary depending on in which country the flow channel 1 is to be installed. Also the distance between the extension plates 11 and the baseline of the bent plate 3 or the lowest point of the plate 3, may vary depending on in which country the flow channel 1 is to be installed. The distance between the extension plates 11 and the baseline of the bent plate 3 or the lowest point of the plate 3 may be, for 30 example, greater than 1/2 of the diameter of the pipe 7.
    20185502 prh 01 -06- 2018 [0053] In FIGURE 3 a schematic side view of a flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 comprises an inlet 4 configured to be coupled to an inlet pipe 5. The flow channel further comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by a bent plate 3. In FIGURE 3, the shown flow channel 1 is straight. The inlet 4 and the outlet 6 may be configured to be coupled to pipes 5, 7 having a diameter of 110 mm or greater than 110 mm, for example to pipes 5, 7 having a diameter in the range between 110 mm and 3000 mm.
    [0054] In FIGURE 4 a schematic perspective view of another flow channel 1 in 10 accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 comprises an inlet 4 configured to be coupled to an inlet pipe 5. The flow channel further comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by a plurality of bent plates 3. In FIGURE 4, the shown flow channel 1 is not straight. The flow channel 1 changes its 15 orientation by about 30 degrees.
    [0055] The bent plates 3 are welded together along a welding line 12. Extension plates 11 are further welded to the bent plates 3 as well as to each other on each side of the flow channel 1. The orientation of the flow channel 1 changes at the welding line 12. Typically, the orientation changes by 30 degrees or less. Thus, material cannot get stuck 20 and clogging of the flow channel 1 can be avoided.
    [0056] The orientation of the first part of the flow channel 1 is identical with the orientation of the inlet pipe 5 and the orientation of the second part of the flow channel 1 is identical with the orientation of the outlet pipe 7. In the shown flow channel 1, the orientation of the flow channel only changes once. According to certain embodiments, the 25 orientation of the flow channel can change several times, for instance. According to certain other embodiments, the orientation of the first part of the flow channel 1 is not identical with the orientation of the inlet pipe 5 and/or the orientation of the second part of the flow channel 1 is not identical with the orientation of the outlet pipe 7.
    [0057] Other jointing methods than welding can be used in accordance with the 30 present invention in order to connect adjacent plates 3, extension plates 11 and/or the frame 10 to each other. For example, adjacent plates 3 may be fixedly attached to each other using adhesive. The term adhesive refers to a material, by means of which plates 3,
    20185502 prh 01 -06- 2018 extension plates 11 and/or the frame 10 can be attached to each other. The adhesive used in the embodiments may be, for example, an epoxy. The adhesive used is selected in such a way that the adhesive used will have sufficient adhesion to the plates 3, extension plates 11 and/or the frame 10. According to certain embodiments, the adhesive selected has a short 5 hardening time, such as a few seconds or less than a minute at most. According to another certain embodiment, the adhesive hardens at least partly within this time so that the adhesive will be able to hold the plates 3, extension plates 11 and/or the frame 10 in place. The final hardening can take clearly more time and the final hardening can even be planned to take place in connection with later process stages. According to other 10 embodiments, adjacent plates 3, extension plates 11 and/or the frame 10 may be attached to each other by mechanical joints. Adjacent plates may, for example, include tongue and groove joints or other mechanical connections. Adhesive may be additionally used in order to seal the joint to avoid leaking of the flow channel 1.
    [0058] Of course, the flow channel 1 may also be located within a man-hole instead 15 of the inspection chamber 2.
    [0059] In FIGURE 5 a schematic front view of another flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 comprises an inlet 4 configured to be coupled to an inlet pipe 5. The flow channel further comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 20 between the inlet 4 and the outlet 6 is formed by bent plates 3. In FIGURE 5, the shown flow channel 1 is not straight. The flow channel 1 changes its orientation by about 30 degrees.
    [0060] In FIGURE 6 a schematic side view of another flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 25 comprises an inlet 4 configured to be coupled to an inlet pipe 5. The flow channel further comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by bent plates 3. In FIGURE 6, the shown flow channel 1 is not straight. The flow channel 1 changes its orientation by about 30 degrees at the welding line 12.
    [0061] In FIGURE 7 a schematic top view of another flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow channel 1 comprises an inlet 4 configured to be coupled to an inlet pipe 5. The flow channel further
    20185502 prh 01 -06- 2018 comprises an outlet 6 configured to be coupled to an outlet pipe 7. The flow channel 1 between the inlet 4 and the outlet 6 is formed by bent plates 3. In FIGURE 7, the shown flow channel 1 is not straight. The flow channel 1 changes its orientation by about 30 degrees as shown by the angle oc. The inlet pipe 5 has a first diameter di and the outlet 5 pipe has a second diameter d2. The first diameter di and the second diameter d2 may be identical or different. Typically, in case that there is only one inlet pipe 5 and one outlet pipe 7, the diameters di, d2 are identical.
    [0062] In FIGURE 8 a schematic perspective view of a further flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow 10 channel 1 comprises two inlets 4, wherein each inlet 4 is configured to be coupled to a respective inlet pipe 5. The flow channel 1 is configured to be coupled to inlet pipes 5 having different orientation. The diameters of the inlet pipes 5 may be identical or different according to certain embodiments. The flow channel 1 further comprises a single outlet 6 configured to be coupled to an outlet pipe 7, wherein the orientation of the outlet pipe 15 coincides with one of the inlet pipes. According to certain embodiments, all pipes 5, 7 may have a different orientation and/or diameter. Additionally, the pipes may arrive and/or depart at different depths in the ground. There is a depth difference between an inlet 4 and an outlet 6 of 1 cm - 2 cm per m length of the flow channel 1, for instance.
    [0063] The flow channel 1 between the inlets 4 and the outlet 6 is formed by only 20 two bent plates 3. Within the flow channel 1, a junction is located. Material flowing through the flow channel 1 from the first inlet 4 and from the second inlet 4 can flow towards the outlet 6 from the junction at the welding line 12. In other words, the flows from the first inlet 4 and from the second inlet 4 are combined to be one flow after the junction.
    [0064] The flow channel 1 is made by only two bent plates 3. The pre-cut plates 3 can be manually bent at the construction site and welded together along welding line 12. Extension plates 11 may be additionally welded to the bent plates 3 or be an integral part of the bent plates 3. The installation of the flow channel 1 is less time consuming and less labour intensive than e.g. bolting a plurality of U-shaped profiles together.
    [0065] In FIGURE 9 a schematic front view of a further flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. The flow
    20185502 prh 01 -06- 2018 channel 1 comprises two inlets and one outlet 6. The flow channel 1 is made by only two bent plates 3.
    [0066] In FIGURE 10 a schematic top view of two cut plates 3 of a yet further flow channel 1 in accordance with at least some embodiments of the present invention is illustrated. Flat plates 3 are cut based on measured or determined information including orientations, diameters and depths in the ground of different pipes. The shape of the plates 3 may be defined by a computer calculation based on the measured or determined information. Defined shape data of the plates 3 may then be provided as CAD data. The plates 3 may then be cut by a CNC machine into the defined shape. A flow channel 1 having two inlets and one outlet can be formed by bending the plates 3 shown in FIGURE 10 against a frame and welding the bent plates 3 together. Of course, the plates 3 may also be cut by another device, for example a plasma burner, or even manually using a saw.
    [0067] According to certain embodiments, the plates 3 may comprise a plurality of grooves in the rear side of the plates 3, i.e. in the side opposite to the side forming the flow 15 channel 1. The grooves improve bending of the plates 3 due to locally decreasing the thickness of the plates 3, thus providing some sort of flexibility. The grooves may be arranged locally in the rear side, for example only where a small bending radius is required. Of course, the grooves may also be arranged over the entire rear surface of the plates. The grooves may be arranged at identical or varying distances to each other.
    [0068] According to certain embodiments, the grooves do not extend to one edge or to the edges of a respective plate 3. Instead, an end of a respective groove is located at a distance of a few millimetres, for example at a distance in the range between 5 mm to 30 mm, from the respective edge of the plate 3. Thus, welding of two adjacent plates 3 to each other is enhanced, while a sufficient flexibility for bending the plates 3 is still provided.
    [0069] The grooves may have identical or different depth, length and/or shape. The depth of a groove may be in the range between 10 % and 70 % of the thickness of a respective plate 3, for instance. The grooves may have, for example, a depth of 5 mm and the thickness of the plate may be, for example, 10 mm. The grooves may be arranged parallel or at an angle to each other. The side forming the flow channel is typically smooth.
