Definitions

  • the invention relates to a sewer structure, in particular a sewer shaft, with a liquid storage space arranged therein, which can be filled via an inlet and cooperates with its outlet as a flushing device, the outlet being emptied into the channel through the floor or one side of the liquid storage space to the structure base.
  • Such a channel structure with a flushing device is known, for example, from US Pat. No. 1,744,266.
  • the liquid storage space empties through the floor, an outflow opening provided for this purpose being closable by means of a bell.
  • This is actuated via a linkage which has an actuating rod which is guided through a standpipe which is mounted in the floor and which engages below a bottom with a trigger blade located there which can be filled with water.
  • a linkage which has an actuating rod which is guided through a standpipe which is mounted in the floor and which engages below a bottom with a trigger blade located there which can be filled with water.
  • a sewer shaft with a flushing device is also known from EP 90 906 919.7.
  • a flushing device designed as a flushing sack is described.
  • This has a self-contained, sack-like outer skin, which forms the liquid storage space, from the sole of which a lifting hose is led up and attached in such a way that it initially rises diagonally above the sack and then finally falls again from the high point.
  • the sack is filled via a connection, for fastening the sack in the manhole it is provided with loops, eyelets or the like.
  • a pot-shaped gully is known from the magazine “Korrespondenz Abwasser", 8/91, pages 1020 to 1027, "Improving the Cleaning Performance of Gullys” and is provided with a flushing device operating in the manner of a siphon.
  • the lifting device is essentially designed as a U-shaped tube, the legs of which are directed downward, one leg being arranged near the gully bottom and the tube being sealed out of the gully in the upper region, and in the other, downwardly directed leg continues. Moving the jack out of the gully requires considerable construction work, since work must be carried out not only within the gully, but also in the area surrounding the gully.
  • a sewer structure in particular a sewer shaft, with a liquid storage space arranged therein, which can be filled via an inlet and which interacts with its outlet as a flushing device, the outlet being emptied into the sewer through the floor or one side of the liquid storage space, in that, separately from the drain of the liquid storage space, an inspection opening connecting the sewer structure with the sewer is provided for the sewer.
  • the channel structure is divided into a storage part, which is formed by the liquid storage space, and a passage zone arranged below the liquid storage space, that is to say a zone in which the liquid can flow unhindered in the area of the structure base and the subsequent channel.
  • the structure base preferably has a channel into which the drain empties.
  • drain should be understood to mean any device which is suitable for emptying the liquid storage space.
  • An example of a sequence is a lifting device; however, a sequence can also be a simple emptying device, for example a manually or automatically operated closure, in particular by means of a float or by external energy, for closing or opening the emptying opening of the liquid storage space.
  • a first basic design of the sewer structure according to the invention with liquid storage space provides that the bottom of the liquid storage space has an opening for a means designed as a standpipe for venting the duct, the standpipe being removable from the ground and the opening for the standpipe representing the inspection opening for the duct .
  • the standpipe inserted into the opening thus prevents liquid from escaping from the liquid storage space through the opening in the floor into the channel during the normal operating state; on the other hand, ventilation of the channel via the standpipe is ensured.
  • an emergency overflow through the standpipe and the opening in the floor is possible Lich.
  • a preferred embodiment of the sewer structure with liquid storage space provides that the structure base or the channel is provided with a cover over its / its entire length and width and the liquid storage space is formed above the cover, the cover opposite the structure base or the channel and the Building wall of the sewer structure is sealed and the cover has a drain opening which is penetrated by the drain pipe of the drain.
  • the principle of this embodiment is thus to seal the structure base or the channel from the area of the channel structure located above it, the space formed above the structure base or the channel taking over the function of the liquid storage space, which is separated from the structure base or the channel .
  • Sewer structures can thus be easily equipped with a flushing device, both when building the sewer structure and by retrofitting.
  • a particularly simple design of the cover is obtained if it is designed as a plate which can be placed on both sides of the channel on the building base and connected to it in a sealed manner.
  • the building base - if it does not reach the upper edge of the inlet or outlet channel - be concreted on, so that the plate represents the cover element of the concrete base which is concreted on.
  • the plate-shaped cover is placed on the concrete base of the building and connected to it.
  • the channel has an essentially semicircular cross section.
  • the cover is designed as a box, which can be placed on both sides of the channel on the structure base and connected to it.
  • the box is expediently formed by two side walls and a top wall and bearing flanges connected to the side walls, the top wall having the emptying opening for the drain.
  • the height of the building channel can be increased by means of the box-shaped cover.
  • the box-shaped cover is placed on the usual base of the sewer structure and then the base of the structure is concreted essentially up to the height of the top wall of the box.
  • the additional inspection opening which can be closed by means of a cover, can be provided in the bottom of the liquid storage space, in particular in the plate or box.
  • Means for ventilating the duct to the outside of the duct structure are preferably provided.
  • the means for ventilation ensure a flow connection between the channel and the upper channel structure entrance. In the event of an undesired, increased fluid accumulation in the fluid storage space, the means for ventilation can act as an emergency overflow.
  • the means for venting the channel can be designed, for example, as a hose, tube or the like.
  • the cover for the channel has the further opening for the standpipe, the standpipe protruding above the light-off level of the drain.
  • both an air connection between the base of the building or the channel and the duct building area located above it, as well as an overflow is ensured. Gases can circulate freely between the duct and the duct structure and through the ventilation openings of the building cover with the outside air. After removing the standpipe from the plate or box, the (revision) opening is freely accessible.
  • the standpipe should be insertable into the relevant opening of the cover just like a drainpipe of the drain. It is therefore possible to remove the standpipe and / or the drain from the cover in a simple manner, which means that the channel and the channel are easily accessible for inspection purposes if the openings are appropriately large. In order to ensure even better access to the channel, it can also be provided that the cover can be removed. For assembly reasons it can consist of several cover parts arranged one behind the other in the longitudinal direction of the channel. A cover part then advantageously has an opening for the flushing device and another cover part has the opening for the standpipe. However, one of several cover parts can also have the openings.
  • a hose, tube or the like penetrates the inside of the drain pipe of the drain designed as a lifting device, the hose, the tube or the like being guided out of the lifting device in a sealed manner and over the liquid level in the storage space protrudes, at which the lifting device starts up, and extends at least as far down to the outlet opening of the drain pipe that the lifting effect is guaranteed.
  • the hose, the tube or the like is advantageously held in the bell and, if appropriate, also in the outlet tube of the lifting device.
  • the closure of another drain could be designed as a tube, which takes over the function of ventilation and the overflow at the same time.
  • the sewer structure is provided with an essentially vertically arranged partition wall which divides the sewer structure into the liquid storage space and a further structural space, the structural base or the channel in the area of the liquid storage space a cover is provided, which is sealed off from the assigned area of the building base or the channel as well as the building wall and the partition wall, the cover having an emptying opening through which the drain empties.
  • This design is based on the principle of separating a vertically extending part of the sewer structure from the remainder of the sewer structure, whereby that part of the sewer structure takes over the function of the liquid storage space and in this structural part the structure base or the channel interacts with the cover, through the opening of which the drain emptied to the base of the building or into the channel, while the other area of the sewer structure serves the purpose of ventilating the sewer and the sewer structure and leaving the sewer accessible or represents the emergency overflow for the liquid storage space.
  • all of the above-described variants relating to the covering can be implemented. Without the drain having to be removed from the assigned cover, it is possible to inspect the sewer structure at any time, that is to say also in the case of liquid stowed in the liquid storage space.
  • the drain should be removable for occasional cleaning of the storage chamber.
  • a third basic design of the sewer structure according to the invention with a liquid storage space provides that the liquid storage space is formed by a component that can be inserted into the sewer structure, the component having an emptying opening of the drain.
  • the independent component is preferably a flexible component that can be inserted into the sewer structure, e.g. can be attached, in particular an open-topped container, which is preferably made of plastic.
  • the component takes up only a part of the clear cross section of the sewer structure, so that the means for venting the duct, as in the second basic design, are formed by the further structural space and through this the duct is easily accessible for revision purposes.
  • FIGS. 1 to 4 shows a conventional sewer shaft 1.
  • inlets 2, 3 open, for example inlet 2 being connected to a street inlet 4 and inlet 3 being connected to the roof drainage of a house 5.
  • any number of inlets can open into the upper region of the manhole 1, at least one.
  • the liquid can flow freely through the inlet (s) or can also be pumped.
  • the sewer shaft has an (outlet) shaft base 6 with a channel 7.
  • the channel 7 penetrates the channel shaft 1 radially, the outer region of the shaft bottom 6 drops towards the channel 7.
  • the cross section of the channel 7 is substantially semicircular.
  • the lower boundary of a circular outlet opening 9 of the manhole 1 is aligned with the bottom 8 of the channel 7.
  • the channel 7 is provided with a cover 10 over its entire length in the manhole 1.
  • This is designed as a box, which is placed on both sides of the channel 7 on the shaft base 6 and is fastened to it via a screw-dowel connection 11.
  • the cover 10 is sealed off in the region of its two end faces 12 from the circumferential shaft wall 13.
  • the two bearing flanges 14 of the box-shaped cover 10, in the area in which the screw-plug connection 11 is effective, can also be sealed off from the shaft bottom 6.
  • the cover 10 consists of two box-shaped cover parts 10a and 10b, which overlap in a sealing manner in the central region.
  • the material of the cover 10 is, for example, stainless steel.
  • the cover part 10a has an outlet opening 16 in the region of its roof wall 15.
  • the drain pipe 17 of a drain in the present case a lifting device generally designated by the number 18, is inserted into this.
  • Lifting devices are fundamentally known and, in the sense of the present invention, they only need to be specified in such a way that the drain pipe 17 that discharges the liquid when the lifter starts up flows through the drain opening 16 into the space of the channel 7 enclosed by the cover 10, the drain pipe 17 in the exemplary embodiment sealed outside in the opening 16 and is connected to the cover 10.
  • the vertically arranged drain pipe 17 is preferably curved in the region of its lower end in the direction of the outlet opening 9 of the sewer shaft 1.
  • the other cover part 10b is also provided with an opening 19 in the region of its roof wall.
  • a standpipe 23 widening in the lower region is inserted into this opening 19.
  • the manhole 1, which can be walked on via crampons 22 or the like, can be converted in a simple manner by anchoring the cover 10 in the form of a box to the shaft bottom 6 and sealing it to the shaft wall 13 and possibly to the shaft bottom 6.
  • the box is then concreted in with profiled concrete, at least up to the height of the roof wall 15, it being necessary to ensure that the openings 16 and 19 in the cover 10 remain free. Concreting results in a shaft bottom 24 which is appropriately inclined.
  • the lifting device 18 and the standpipe 23 are then inserted into the cover 10.
  • a liquid storage space 25 is thus formed in the manhole 1 above the channel cover.
  • the liquid flows through the inlets 2 and 3 into the upper region of the manhole 1 and collects in the liquid storage space 25. It rises until it has reached approximately level D (FIG. 2) and the lifting device 18 thus starts up.
  • the standpipe 23 ends above the level D, so that it is ensured that, in the normal case, the liquid enters the channel via the lifting device 18 through its drain pipe 17 and rinses the drain channel.
  • the ventilation of the duct and the shaft is ensured via the standpipe 23 and the ventilation openings of the manhole cover. If, for whatever reason, the lifting device 18 is disturbed and does not start, the liquid which then accumulates over the level D can flow into the channel 7 via the standpipe 23 which functions as an overflow.
  • the relatively large opening 19 in the cover 10 serves the purpose of being able to carry out a revision of the channel 7 and the channel 35 after removing the standpipe 23. With a correspondingly large dimensioning of the opening 16, a revision can also be carried out as a result.
  • the variant according to FIG. 5 differs from that according to FIGS. 1 to 4 in that the area of the shaft bottom on both sides of the channel 7 initially changes from the level of the (base) shaft bottom 6 to the level of the shaft bottom 24 (see corresponding illustration according to FIG. 3). has been concreted and then a cover 10 designed as a plate is placed on both sides of the channel 7 on the shaft bottom 24 and connected to it in a sealed manner. If the channel 7 is deep enough, the usual manhole base 6 may not be concreted on and the plate-shaped cover 10 may be connected directly to it. Then, as previously described, the lifting device 18 and the standpipe 23 are inserted into the openings 16 and 19 of the plate-shaped cover 10 and connected to the cover 10. Parts corresponding to the embodiment according to FIGS. 1 to 4 are designated with the same reference numerals in the embodiment according to FIG.
  • FIG. 6 illustrates a variant in which the function of the standpipe 23 is integrated in the drain, in the present case the lifting device 18, so that a separate opening 19 in the cover 10 is not necessary.
  • the drain pipe 17 is formed in two parts, a manifold section 17a having a circumferential flange 29 which is inserted into the cover 10 in the region of the opening 16 and fastened there in a sealed manner.
  • a second, straight pipe section 17b can be inserted into the elbow section 17a.
  • the two sections 17a and 17b are sealed off from one another via a sealing ring 32.
  • a hose 26 penetrates the inside of the drain pipe 17 of the lifting device 18, which is only shown in a very simplified form, and furthermore penetrates the bell 28 of the lifting device 18 in a sealed manner in the region of the roof wall 28a and is held here and possibly via webs 27 in the drain pipe 17.
  • the hose 26 projects beyond the maximum liquid level D in the liquid storage space 25, at which the lifting device 18 starts and extends down to below the inlet opening 39 of the lifting bell open at the bottom, specifically to the outlet opening of the drain pipe 17.
  • the exact structure and the exact mode of operation of the lifting device 18 are - except for the representation of the ventilation hose 26 - described in the German patent application P 41 37 768.0. Parts which correspond to the embodiments according to FIGS. 1 to 5 of the present application are denoted by the same reference numerals in the embodiment according to FIG.
  • the sewer shaft 8 is provided with a vertically arranged partition which divides the sewer shaft 1 into the liquid storage space 25 and a further shaft space 34.
  • the channel 7 is provided with the cover 10 only in the area of the liquid storage space 25, which is placed and connected to the concreted manhole base 24 in the manner of the embodiment according to FIG. 5, whereby it is in the assigned area of the channel 7 opposite the concreted manhole bottom 24 Shaft wall 13 and the partition 33 is sealed.
  • the plate-shaped cover 10 has the opening 16, which is sealed by the drain pipe 17 of the lifting device 18.
  • the ventilation and the emergency overflow as well as the revision of the channel 35 take place via the shaft room 34. Parts which correspond to the above-described embodiments are designated with the same reference numbers in the embodiment according to FIGS. 7 and 8.
  • FIG. 9 illustrates an embodiment in which an open-topped container 36, which for example is made of flexible material and is provided with a stiffened bottom 36a, is suspended in the duct shaft 1 through the shaft cover.
  • the container 36 does not extend over the entire clear cross section of the sewer shaft and ends with its bottom 36a at a distance from the shaft base 8, so that the further shaft space 34 is formed below and next to the container 36.
  • the container 36, through which the liquid storage space 25 is formed has in the region of the upper outer edge which abuts the shaft wall 13, a plurality of loops 37 which can be hooked into the corresponding number of hooks 38 connected to the shaft wall 13. If appropriate, the container 36 can also be fastened to the shaft wall 13 in the region of its lower edge.
  • the bottom 36a of the container 36 is provided with the opening 16 which is sealed by the drain pipe 17 of the lifting device 18.
  • parts which correspond to the above-described embodiments are identified by the same reference numerals.
  • the component 36 illustrated in the embodiment according to FIG. 9 does not necessarily have to be hooked into the sewer shaft, instead it can be placed on the shaft bottom, for example, and the flushing device emptied directly into the channel. This does not rule out the fact that when the container rests on the channel base, fastening means are nevertheless provided for it. In this variant, too, the ventilation and the emergency overflow as well as the revision of the duct 35 take place via the shaft space 34.
