Definitions

  • the invention relates to a method for renovating a sewer manhole by means of a liner, to a liner manufactured using the method, and to an apparatus for manufacturing the liner.
  • Sewerage systems in particular manholes, are subject to a very wide variety of thermal, chemical, and hydrological stresses. Trades and industry, among others, make a substantial contribution to high operational stress. Dairies, breweries or the chemical industry in general, for example, introduce considerable quantities of particularly aggressive substances that, by themselves or by admixture with further incoming substances, initiate chemical reactions while flowing.
  • GRP glass-reinforced plastic
  • a further method therefore provides for introducing a tubular “inliner” into a sewer system, pressing it against the sewer wall with compressed air, and lastly curing it with a UV light source.
  • DE 39 22 351 A1 describes for this purpose a method for renovating drainage pipes using a resinified inner pipe that is introduced in an axial direction into the relevant sewer segment, unfolded by an expandable bladder, and then cured.
  • DE 43 26 503 C2 discloses the manufacture of a tubular lining sleeve of arbitrary length. Such a sleeve is unsuitable for branches and sewer manholes, however, in particular manhole necks, especially since the latter in most cases taper conically.
  • DE 699 25 045 T2 is a lining device for sealing and reinforcing the walls of a manhole using a sleeve that is assembled from at least three plies, which are joined to one another by seams and of which the center ply seals the liner.
  • DE 10 2009 050 084 discloses a multi-layer sleeve as well as a method for manufacturing it, which can be used for the renovation and lining of pipelines.
  • the sleeve is continuously manufactured at a constant diameter, for which purpose a flat film is welded at its overlapping longitudinal edges and then drawn through an assembly tube. Simultaneously, longitudinal strips impregnated with resin are laid onto the assembly tube; these are pulled off together with the inner sleeve formed by the flat film, and are intended to connect to one another behind the tube end.
  • DE 697 02 876 T2 describes and depicts a plastic liner for a manhole and a method for coating it.
  • the liner is made up of a pouch, initially applied in a flat shape, that is inflated after introduction into the manhole, although crumpled areas and creases in conical transition segments are unavoidable.
  • the object on which the invention is based is to describe a system for renovating a sewer manhole in order to achieve the following objectives:
  • FIG. 1 is a schematic longitudinal section of a sewer manhole
  • FIG. 2 is a perspective depiction of a mold during the wrapping and laying of a liner in accordance with the invention
  • FIG. 3 shows various modules for use in an apparatus according to FIG. 4 ;
  • FIG. 4 is a schematic sectioned depiction of an apparatus for manufacturing a manhole liner in accordance with the invention
  • FIG. 5 shows a possible cross section in plane V-V of FIG. 4 ;
  • FIG. 6 shows a wrapping apparatus for use in the apparatus of FIG. 4 ;
  • FIG. 7 is a schematic depiction during the introduction of a liner into a sewer manhole
  • FIG. 8 shows the liner depicted in FIG. 7 in the expanded final state
  • FIG. 9 schematically depicts a fastening apparatus for ladder rungs
  • FIG. 10 is a plan view of a lined manhole
  • FIG. 11 is an enlarged depiction of a portion of FIG. 10 ;
  • FIG. 12 shows the routing of leads to a device
  • FIG. 13 shows the introduction of leads through the back side into the device
  • FIG. 14 shows the introduction of leads through the outer side into a device
  • FIG. 15 shows a variant of FIG. 12 having a routing conduit
  • FIG. 16 is a view of the routing conduit of FIG. 15 ;
  • FIG. 17 is a view of a sector of a mold having push-through pegs for fastening ladder rungs
  • FIG. 18 is an enlarged depiction of a push-through peg in accordance with FIG. 17 ;
  • FIG. 19 is a cross section through part of the mold, of the liner, and of a fastening plate for a ladder rung;
  • FIG. 20 shows a portion corresponding to FIG. 19 , after expansion and curing of the liner in the manhole and fastening of a ladder rung.
  • FIG. 1 shows by way of example a sewer manhole 10 as defined in DIN V4034-1:2004-08.
  • Sewer manholes of this kind have an eccentric cone 12 that sits on cylindrical barrel sections 14 which are positively connected to one another.
  • a step (berm 18 ) into which is recessed a gutter 24 that creates the connection to a sewer pipe 22 .
  • Sitting on eccentric cone 12 as the upper termination of manhole 10 is a manhole covering 26 made up of a frame 28 having support rings 30 and a cover 32 . Support rings 30 allow adjustment to grade. Once cover 32 has been lifted, it is possible to climb down to step 18 at the bottom of the manhole via ladder rungs 36 mounted on the cylindrical manhole wall 34 .
  • Sewer manholes 10 often deviate from standardized stipulations.
  • a very wide variety of configurations exist both in the region of eccentric cone 12 with its conical transition, and in the lower manhole part having berm 18 .
  • the manufacturing method provided in accordance with the invention allows both standard shapes and almost all special shapes to be lined.
  • FIG. 2 shows the embodiment of a mold 38 , provided in accordance with the invention and arranged horizontally, for wrapping and laying a manhole liner 50 ( FIGS. 7 and 8 ) that reproduces the inner surface of sewer manhole 10 but whose diameter is smaller by a specific dimension in order to take into account the thickness of manhole liner 50 and the clearance necessary therefor upon introduction into manhole 10 .
  • Mold 38 is manufactured as a hollow member, for example from sheet metal that is assembled from a variety of modules in accordance with the shape of the manhole and is used in an apparatus 20 indicated in FIG. 4 .
  • the example of FIG. 3 shows a number of different modules 38 - 1 , 38 - 2 , 38 - 3 .
  • FIG. 4 schematically depicts apparatus 20 for receiving, with rotary drive, a mold 38 with which a liner 50 in accordance with the invention can be manufactured.
  • Extending from a column 42 is a horizontal axle 100 that is fastened nonrotatably on column 42 and on which a drum 102 is mounted rotatably via rolling or plain bearings 104 .
  • a controllable-speed motor 106 which is attached to column 42 and whose shaft 108 imparts rotation to drum 102 via a gearbox 110 , serves to drive drum 102 .
  • a pneumatic or hydraulic drive is alternatively also conceivable.
  • mold 38 is embodied as a hollow member that is assembled from juxtaposed modules whose dimensions (length, diameter, taper angle) correspond to the shape of the manhole to be lined.
  • the example depicted shows a large cylindrical module 38 - 1 for lining the vertically superimposed barrel sections 14 , the length of which module corresponds to the manhole depth in the cylindrical region upwardly adjacent to berm 18 (see FIG. 1 ) and is generally a multiple of the diameter.
  • the subsequent module 38 - 2 serves for manufacture of the liner segment for eccentric cone 12 , which is followed by a small cylindrical module 38 - 3 to terminate the cone.
  • the juxtaposed modules 38 - 2 , 38 - 3 are connected nonrotatably to the closed end of drum 102 via positive coupling elements 112 .
  • Liners for other manhole cross sections can of course also be produced, for example by combining different modules or by means of polygonal modules 38 - 1 ′.
  • FIGS. 4 and 5 indicate the possibility of subdividing at least the large module 38 - 1 into two or in this case four circle segments 118 , so that the diameter can be modified.
  • Each segment 118 is mounted, by means of at least one radially inwardly protruding foot 120 , in a guide 122 that projects from drum 102 . This allows segments 118 to be steplessly displaced in a radial direction in the direction of the arrows shown, for example at a 2:3 ratio (see FIG. 5 ), to enable at least two adjacent nominal diameters to be generated.
  • arc-shaped bridging elements 124 that are pivot-mounted at one end 126 on the adjacent segment 118 can be provided. Radial displacement of segments 118 can occur in motorized fashion; this is not depicted further.
  • Mold 38 is mounted in cantilevered fashion on axle 100 via drum 102 . Its right-hand end (in FIG. 4 ) is thus free and can be adapted, for production of the variously embodied liners 50 , to the shape respectively existing in the region of eccentric cone 12 .
  • FIG. 2 schematically shows the method for manufacturing liner 50 with the aid of mold 38 .
  • an inflatable film sleeve 40 ( FIG. 7 ) is pulled onto mold 38 , the purpose of said sleeve being to protect mold 38 from adhesive so that liner 50 , once produced, can ultimately be pulled off.
  • Film sleeve 40 is feathered in the tapered cone region, i.e. notched from the free end in a longitudinal direction, whereupon the overlaps resulting therefrom are adhesively bonded from the outside. It is also possible to fit prefabricated cut pieces of film onto one another.
  • a laterally arranged wrapping apparatus 130 carries rolls 44 of an extensible textile strip 46 , as a rule made of glass-fiber material, that enables mold 38 to be wrapped at different angles of inclination with respect to the axis of mold 38 .
  • wrapping apparatus 130 has a carriage 132 that carries a roll 44 and is movable back and forth relative to apparatus 20 in a longitudinal direction in the direction of arrow W of FIG. 4 .
  • extensible textile strips 46 ′ can also be laid axially in a longitudinal direction. These are embodied in FIG. 2 as narrow bands; it is also possible instead to use wide strips 46 ′ of which one, two, or three respectively cover somewhat more than the circumference of mold 38 . In a context of multiple plies, the overlaps are offset from one another in a circumferential direction in order to largely preclude accumulations of material.
  • Axially arranged longitudinal strips 48 ensure that the composite produced is cohesive in an axial reaction and holds together against the weight of liner 50 upon installation in manhole 10 .
  • the high-tensile-strength longitudinal strips 48 can be guided out via the tapered neck portion in order to facilitate suspension of the completed liner 50 and introduction into sewer manhole 10 .
  • Precut textile pieces 98 whose shape corresponds to the tapered surface of eccentric cone 12 , can be incorporated into the wrapping in the region of the tapered eccentric cone 12 .
  • the wall thickness can be different at different manhole depths so as to adapt to different applied loads.
  • FIG. 11 indicates that a metal band 55 that is preferably made of an aluminum adhesive tape can be applied axially onto the outer side of protective sheath 52 at 0°, i.e. at the point where, with liner 50 in the vertical installation position, the perpendicular is continuous from bottom to top and is not interrupted by the taper of eccentric cone 12 .
  • This band allows the wall thickness of liner 50 to be checked after curing, at every manhole height, with an eddy current meter.
  • the diameter of mold 38 can be made slightly smaller, for which purpose segments 118 are displaced radially inward so that the completed GRP liner 50 can be stripped off in an axial direction over the free end of mold 38 (indicated with dashed lines).
  • FIG. 7 shows the introduction of GRP liner 50 into sewer manhole 10 .
  • a plate 54 that fills up the manhole cross section is mounted at the lower end of liner 50 as a working platform and assembly aid.
  • Fastening panels 56 can then be temporarily fastened on manhole wall 34 , for example by adhesive bonding 82 , in the pattern of a two-row or single-row arrangement of ladder rungs 36 to be installed later (see FIG. 9 ).
  • a circumferential, permanently elastic seal 60 is mounted on manhole wall 34 just above berm 18 (in the case of concrete manholes, below the lowest joint 58 between the lowest barrel section 14 and berm 18 ). This seal creates sealing between manhole liner 50 and manhole wall 34 .
  • a pressure-tight bag 66 is inserted into the inner film sleeve 40 ; into this will then be lowered, via a hauling rope 78 , a disk 62 that, in the final lowest position, abuts on plate 54 at the step (berm) 18 when GRP liner 50 has assumed its intended position in manhole 10 .
  • the upper end of bag 66 is closed off in pressure-tight fashion with a cover 64 .
  • the latter has a connector 68 for introduction of a medium under positive pressure, preferably compressed air, so that bag 66 can be inflated.
  • Cover 64 furthermore has an opening 70 for the introduction of thermal energy, preferably via a cable 72 for powering a UV or infrared radiation source 74 , and optionally a further opening for a cable that leads to a digital camera.
  • GRP liner 50 that has been prepared for installation is then suspended from a hoist 76 and lowered into sewer manhole 10 so that its shape coordinates with the shape of the manhole in terms of vertical and rotational position. Bag 66 is then expanded by positive pressure so that GRP liner 50 unfolds and abuts tightly against manhole wall 34 , against sealing ring 60 at the lower end, and against fastening panels 56 .
  • the force acting on disk 62 as a result of the positive pressure is braced by plate 54 .
  • the compressive force acting on cover 64 is absorbed by lower disk 62 via hauling rope 78 that extends axially through bag 66 , and disk 62 arrives at a centered location inside manhole 10 .
  • Radiation source 74 for curing GRP liner 50 is switched on and is moved up and down by means of its power cable 72 along hauling rope 78 until liner 50 is cured. Radiation source 74 moves approximately in the center axis of the liner so that uniform curing at all locations is ensured.
  • FIG. 7 shows the renovated sewer manhole 10 with the final liner 50 .
  • fastening ladder rungs 36 There are several possibilities for fastening ladder rungs 36 .
  • the attachment locations on the inner surface of GRP liner 50 are marked using the same dimensions that were previously used when attaching fastening panels 56 .
  • Fastening holes for ladder rungs 36 are then drilled into fastening panels 56 .
  • Ladder rungs 36 can be fastened using bolts and cap nuts 80 that are attached behind fastening panels 56 .
  • Fastening panels 56 which are covered by liner 50 , can be equipped with a small permanent magnet 128 for localization thereof.
  • Measurement devices, control devices, and other devices 84 are increasingly being mounted in sewer manholes 10 .
  • the cables and leads 86 connected thereto are usually routed along manhole wall 34 , where they interfere with cleaning.
  • leads 86 can be routed in the space between liner 50 and manhole wall 34 , so they cannot interfere with cleaning or be damaged in the course of work in manhole 10 .
  • devices 84 are bolted onto fastening panels 56 .
  • cap nuts 80 also means that the drilling pattern for fastening them need not be determined until later.
  • Cable passthroughs can also be attached later. Cables 86 are usually guided in protective pipes 88 in the ground to manhole 10 . There an orifice 90 of sufficient size is introduced into manhole wall 34 using a core drill. Flexible plastic insulating tubes 92 , or dimensionally stable but flexurally soft plastic conduits 94 ( FIG. 16 ), lead from orifice 90 on the inner surface of manhole wall 34 to fastening panel 56 . They are at first provisionally fastened onto manhole wall 34 by adhesive bonding 82 .
  • hoses rather than electrical leads 86 can also be routed in this manner.
  • the diameters of insulating tubes 92 or the dimensions of cable conduits 94 encounter limits in terms of the strength of GRP liner 50 , and must be designed in accordance with local forces.
  • liner 50 When liner 50 has been installed, it conforms against fastening panels 56 and against insulating tubes 92 or cable conduits 94 , and secures them in their final position.
  • the passthrough for leads 86 through the manhole liner to device 84 must be sealed using cable fittings.
  • Orifice 90 in manhole wall 34 must be closed off with assembly foam 96 until it is used for leads 86 . Assembly foam 96 can easily be removed before leads 86 are routed. After routing, orifice 90 can be sealed again in the same manner.
  • FIGS. 12 to 16 have the advantage that the supply lines are routed behind manhole liner 50 made of GRP. In addition, anchor holes in manhole wall 34 , and thus possible leakage points, are avoided.
  • FIGS. 17 to 20 show one possibility for manufacturing the fastening system for ladder rungs 36 , as indicated in FIG. 11 .
  • ladder rungs 36 are bolted not onto fastening panels 56 as shown in FIGS. 12 to 14 , but instead onto fastening plates 53 of approximately square shape having edges 57 that taper in beveled fashion.
  • FIG. 17 depicts a circle segment of mold 118 on which push-through pegs 63 are placed in pairs corresponding to the intended arrangement of fastening bolts 73 for ladder rungs 36 .
  • these pegs 63 Upon manufacture of the textile composite for liner 50 on mold 118 , these pegs 63 generate holes 67 that serve for subsequent reception of embedded nuts 80 that are part of fastening plates 53 .
  • push-through pegs 63 are removed outward from their latched engagement or, carried by an apparatus, they are countersunk together below the support surface of mold 38 .
  • FIG. 18 shows an example of a push-through peg 63 that can alternatively have a rotationally symmetrical tip 65 or an oblique tip 65 ′.
  • Sockets 61 into which shank 114 of push-through peg 63 latches with the aid of a spring washer 116 , are fastened in mold 38 .
  • the desired rotational position of peg 63 having an oblique tip 65 ′ can be adjusted via a slot 115 in shank 114 .
  • Located in tip 65 , 65 ′ is a transverse orifice 117 for insertion of a tool with which peg 63 can be pulled out again once liner 50 is complete.
  • fastening plates 53 are made of synthetic resin, for example GRP, into which two respective nuts 80 are embedded. Fastening plates 53 are placed onto the textile composite of liner 50 in such a way that projecting parts 69 of nuts 80 penetrate into holes 67 . Then, as indicated in FIG. 17 , fastening plates 53 are temporarily secured with adhesive tapes 71 . Lastly, as already explained, liner 50 is covered with a protective sheath 52 that, in this method, does not need to be perforated for fastening ladder rungs 36 .
