Definitions

  • the invention relates to a street drain with an upper inlet and a shaft-like housing, which is usually designed as an upright pipe and is closed at the bottom by a base.
  • the street drain also has an outlet, which is arranged in or above the ground and in any case lower than the inlet. Street drains of this type are known from practice. They serve to drain street surfaces and to lead surface water, which may have occurred due to precipitation and which enters the shaft-like housing through the inlet, out of the housing through the outlet.
  • the outlet is usually connected to the sewer system, so that the water is drained from the street surface by means of the street drain and fed into the sewer system.
  • the street drain is used in particular in streets to direct surface water from a road surface into the sewer system.
  • other areas of application can also be more general in draining water and in particular directing it into the sewer system, for example water that has collected in squares or courtyards, in troughs or shafts.
  • the street drain can be designed in an identical manner in each case. or in different designs, in particular different sizes.
  • the concept of road gully used in the context of this proposal is therefore not limited to the fact that the road gully serves to drain a road and has the hydraulic capacity required for this purpose.
  • the invention is based on the object of improving a generic street drain in such a way that it helps to relieve the municipal sewerage system during major rainfall events and enables support of the municipal vegetation regardless of the major rainfall events.
  • the invention proposes that the housing of the street drain has a second outlet, which is also arranged lower than the inlet.
  • a guide element which is arranged between the inlet and the second outlet, serves to guide liquid flowing into the housing, such as surface water flowing into the street drain, to the second outlet.
  • the first outlet is not shut down or made redundant as a result; rather, the guide element and/or the second outlet has an overflow opening that opens into the interior of the housing, so that an amount of liquid that occurs and exceeds the absorption capacity of the second outlet passes through the overflow opening into the interior of the housing and thus to the first outlet. Since, as expected, the liquid flowing into the street drain consists essentially of water, water is often mentioned below instead of the more general term liquid, but only as an example and representative of liquids in general.
  • the street drain according to the invention therefore relieves the burden on the sewer system, since the surface water is preferably guided into the second outlet by means of the guide element and only the excess that occurs, the amount of liquid of which exceeds the absorption capacity of the second outlet, enters the first outlet and thus into the sewer system.
  • the invention is based on the assumption that the second outlet is not connected to the sewer system, but can be used for another use of the water, so that in the sense of the term "sponge city", the amounts of liquid that occur due to precipitation are retained and can be made available either immediately or at a later time, without burdening the sewer system with this water.
  • the surface water is preferably guided into the second outlet by means of the guide element.
  • the guide element can be deactivated, as will be explained in more detail later, or a partially effective guide element can be used which is designed in such a way that it does not guide the entire amount of water from the inlet to the second outlet like a fully effective guide element.
  • a partially effective guide element can be so narrow that water flowing down from the inlet also partially flows past the guide element.
  • the partially effective guide element has openings in the form of holes, slots or the like, so that a portion of the amount of water guided via the guide element exits the guide element into the housing of the street drain and reaches the first outlet.
  • the second outlet can be used to lead the water to a storage tank designed as a trench or cistern, so that it can be used from this storage tank during dry periods. can be taken out.
  • a reservoir also offers the possibility of treating the water, e.g. chemically or biologically, or mechanically by filtration or sedimentation, so that the water in the reservoir can not only be stored but also improved in quality.
  • the second outlet can be used to immediately drain the water that has entered the street drain without intermediate storage, whereby by means of suitable drainage pipes the water can be distributed over a larger area or directed to a location away from the street drain for infiltration.
  • the water flowing out of the second outlet can be specifically used to irrigate municipal vegetation. For example, along the street in which the street drain is located, by means of drainage pipes that allow liquid to escape and are connected to the second outlet, the water led into the second outlet can be led into or under the root area of the vegetation in question.
  • the Both outlets of the street drain should be at the same height.
  • the second outlet in the street drain is arranged higher than the first outlet. This simplifies the manufacture of the street drain, since street drains, in which the only outlet to date is typically provided deep down in the housing, can be designed according to the invention with little effort by arranging the second outlet provided according to the invention higher than this outlet. In addition, this ensures that excess liquid that reaches the interior of the housing from the guide element and/or the second outlet automatically flows downwards and to the first outlet and can then be drained from the street drain into the sewer system through the first outlet. Finally, the higher arrangement of the second outlet makes it possible to direct water that gets into the second outlet close to the ground to plants such as grasses or flowers that do not have deep roots. The possibility of laying an irrigation line deep below the ground is not excluded by a comparatively high second outlet, since the liquid can easily flow from the second outlet down to the irrigation line.
  • the street drain can be brought into a working configuration or a resting configuration.
  • the working configuration refers to a design of the street drain in which the guide element guides the liquid to the second outlet.
  • the resting configuration refers to a Design of the street drain in which the line created by the guide element between the inlet and the second outlet is interrupted, i.e. the guide element is deactivated in its relevant function. This is advantageous, for example, for the application described, in which the water that enters the second outlet is used to water plants.
  • the street drain can be brought into its rest position so that the correspondingly contaminated water is not fed to the plants but is drained into the sewer system via the first outlet.
  • the rest configuration can be created, for example, by making the guide element impassable for liquid by means of a cover, a plug or the like, so that no liquid can flow into the guide element, flow through the guide element or flow out of the guide element.
  • the two working and resting configurations of the street drain are created by the guide element being movable between the correspondingly designated working and resting positions.
  • the working position means that the guide element is aligned in such a way that it guides the liquid to the second outlet.
  • the resting position refers to an arrangement of the guide element in which this line created by the guide element between the inlet and the second outlet is interrupted, i.e. the guide element is deactivated in its relevant function.
  • the resting configurations of the street drain can thus be created without the use of additional components - such as a cover, a plug or the like - which simplifies the handling of the street drain because such additional components do not need to be stored while the street drain is in its working configuration and, accordingly, cannot be missing when the street drain is to be brought into its rest configuration.
  • additional components such as a cover, a plug or the like - which simplifies the handling of the street drain because such additional components do not need to be stored while the street drain is in its working configuration and, accordingly, cannot be missing when the street drain is to be brought into its rest configuration.
  • the mobility of the guide element can be achieved by a person entering the housing and manually handling the guide element if the diameter of the respective housing is large enough.
  • the guide element can be removed from its holder and reinserted in a different orientation.
  • the mobility of the guide element can be achieved by means of a handle, so that firstly it is not necessary to let a person enter the housing and secondly the mobility of the guide element can be made possible without any problems even with smaller housing diameters.
  • the handle can be for example, pull ropes, rods or the like can be used.
  • the movement of the guide element between its working position and its rest position can also be carried out by an electric motor, so that a minimum amount of time is required for the personnel to be able to effect this movement.
  • the movement of the guide element can be effected not only from outside the housing, but even from a greater distance from the housing, so that, for example, several guide elements, which are arranged in several housings distributed over a larger area, can be controlled practically simultaneously from a control station and can be switched between summer and winter operation, for example, by moving them from their working to their rest position.
  • the guide element is arranged loosely in the housing in such a way that it can be lifted out of the housing from outside the housing through the inlet.
  • the guide element has a holding section so that it can be grasped by means of a shaft hook, which is always used when working on the street drain, e.g. to hold a cover for the street drain.
  • Arranging the guide element loosely in this context means that the guide element, in contrast to a permanently mounted installation element, e.g. glued or screwed to the housing, is freely movable in that it can be removed from the housing from the outside, namely lifted out of the housing upwards through the inlet opening. This means that maintenance personnel do not need to climb into the street drain in order to be able to handle the guide element.
  • “Loose” in this context does not exclude the guide element being secured in its desired position, such as the working or rest position, e.g. by a pivoting safety bracket or the like, which can also be operated from the outside, for example with the aforementioned manhole hook, a cable pull or the like.
  • the possibility of removing the guide element from the housing serves for maintenance of the road gully and also for maintenance of the guide element itself, e.g. a filter surface if the guide element is provided with a filter, or also for fitting or removing a cover or plug if in this way the road gully is to be reconfigured between the aforementioned working and rest configurations.
  • a settling basin is arranged in the flow path created for the liquid between the guide element and the second outlet.
  • the settling basin can be arranged in the guide element so that the settling basin together with the guide element can be removed from the street drain and emptied or cleaned.
  • the settling basin can be arranged in the second outlet so that the guide element can be designed to be small and light and can be easily accommodated in the housing and moved between working and rest positions and, if necessary, removed from the housing.
  • the settling basin can separate particles from the liquid before the liquid flows into a line that connects to the second outlet, thus enabling correspondingly long maintenance intervals, e.g. to flush this line free of sediment.
  • the street drain has a coarse filter in the direction of flow of the liquid between the inlet and the guide element.
  • This can, for example, be the typical insert known from practice, such as the sludge bucket in the form of a bucket made of galvanized sheet steel with openings.
  • the coarse filter serves to hold back leaves, small animal carcasses, pieces of branches and the like so that they cannot get into one of the outlets of the street drain.
  • a treatment substrate is arranged in the flow path taken by the liquid in front of the second outlet, which has a mechanical, chemical and/or biological filter effect on the liquid flowing through the substrate.
  • Such substrates are known per se; their composition can vary, e.g. to adapt to the type and amount of substances that are to be expected in the surface water that flows into the street drain.
  • a substrate can be arranged in the guide element, or also in the second outlet.
  • the pipe leading away from the second outlet can also be partially filled with such a substrate, e.g. in its lower peripheral section, and the outlet openings of the pipe can also be arranged in this lower peripheral section, so that the water from the pipe first passes through the substrate before it can exit the pipe.
  • the guide element runs diagonally downwards from the inlet to the second outlet.
  • the guide element can simply be set diagonally into the housing of the street drain. Its lower end rests on the second outlet and its upper end rests against the housing wall.
  • the guide element has a seal at its upper end that extends to the housing. This ensures that no gap is created between the upper end of the guide element and the housing through which water could escape. Rather, the seal ensures that the water flowing down from above in this area is also captured and guided to the second outlet by the guide element.
  • the mentioned seal is designed as a flat seal and consists of a flat material, for example in the form of a truck tarpaulin, a rubber sheet or the like, possibly with textile reinforcement, so that the seal can be cut inexpensively from a sheet, sheet or roll.
  • the seal made of the flat material is dimensioned so large that it is deformed in the manner of a trough and forms a sealing apron when the guide element is in its working position in the street drain, whereby the deformation of the seal results from the fact that it rests against the housing.
  • This design of the guide element and its seal ensures that water reaching the sealing apron from above is guided into the guide element.
  • the invention also relates to a guide element which forms part of the road gully according to the invention by being arranged in its use arrangement between the inlet and the second outlet of the road gully and directing liquid flowing into the housing through the inlet to the second outlet.
  • the guide element has a channel.
  • the channel can have a square or circular cross-section and can be cut from a pipe, for example.
  • a channel allows a larger amount of water to be absorbed, so that, for example, in the form of a "sponge city", as much of the precipitation as possible can be retained and seeped away without entering the sewer system.
  • the design of the guide element as a channel means that the guide element, when it can be brought into a rest position, can cover the second outlet like a hood and thus provide particularly reliable protection against the ingress of liquid flowing down.
  • the guide element is wider than the second outlet in order to absorb as much of the liquid as possible that flows downwards from the inlet of the street drain.
  • the gutter in one embodiment has a reducer which reduces the cross-section of the gutter through which the flow can pass. This ensures on the one hand that the comparatively wide gutter absorbs a lot of the liquid flowing down, and on the other hand that, despite the width of the gutter, no liquid flows past the second outlet from the guide element. Instead, the liquid in the gutter is concentrated by means of the reducer in the middle, deepest area of the gutter.
  • the reducer has a flow-through opening which is arranged centrally within the channel cross-section.
  • the reducer can therefore be designed in a particularly simple and also particularly economical manner, so that no complex shaped part, for example a funnel-shaped part, is required.
  • the reducer can be designed in a straight line in the form of a plate which is inserted into the channel or limits the channel at the front and which has the desired opening at the appropriate location, for example at the edge, so that the opening is limited partly by the reducer and partly by the channel itself.
  • the channel is covered by a sieve, so that water flowing or dripping into the channel from above first passes through the sieve before it reaches the channel.
  • a sieve can, for example, be a fabric made of natural or synthetic fibers, it can be a grid made of plastic or metal. or as a porous ceramic element, or the like; the only important thing is the desired filter function by means of the corresponding pore size or mesh width of the sieve.
  • the guide element has a holding section that can be grasped by means of a shaft hook.
  • the holding section can be a hook, a closed eyelet, a hole in a wall surface such as in the mentioned gutter, or the like.
  • the only important thing is that the holding section makes it possible to grasp and move the guide element by means of a shaft hook, so that the guide element can be removed from the housing of the street drain if necessary, but at least can be moved within the housing, e.g. between its working position and its rest position.
  • the holding section and the use of the shaft hook enable the guide element to be handled from outside the street drain.
  • the guide element is provided with an outwardly projecting seal at one of its two ends. If the guide element has a gutter, for example, the seal extends beyond the gutter in the axial direction of the gutter.
  • the seal makes it possible to bridge a gap between the guide element and the housing of the shaft drain, so that water hitting from above does not get into such a gap and is lost for the second outlet. Instead, the water is caught by means of the seal, which forms an extension of the guide element, and can be guided to the second outlet.
  • the seal mentioned is made of a flat material. This enables a particularly cost-effective production of the seal as a cut from a flat material, which is available as a plate or sheet or on a roll as a semi-finished product, and furthermore it enables a Optimal adaptation of the seal to bridge the gap, as the flat material can be easily deformed into a trough-like sealing apron and placed against the wall of the shaft-like housing of the street drain.
  • the term street drain used in the context of the present proposal is not limited to the fact that the street drain serves to drain a street and has the hydraulic power required for this.
  • the inlet is arranged higher than the outlet.
  • the invention therefore does not only relate to devices in which the inlet is located at the upper axial end of the shaft-like housing, as is the case with a street drain.
  • the invention also relates to the use of the guide element in devices which are technically referred to as shafts and in which the water - e.g. through a pipe - enters the shaft-like housing from the side, i.e. the inlet is arranged in the circumference of the shaft-like housing and possibly below its upper axial end.
  • Fig.1 shows a vertical section through a first embodiment of a street drain 1, the cutting plane running lengthways through outlet pipes of the street drain.
  • This has a shaft-like housing 2 in the form of a pipe section.
  • a base 3 is inserted obliquely into the housing and leads water, which enters the housing 2 from above, to a first outlet 4.
  • the first outlet 4 is connected to a municipal sewer system is connected.
  • a coarse filter 5 is arranged in the housing 2, which can be designed, for example, in the form of a sludge bucket known from practice.
  • the coarse filter 5 extends only over a part of the upper free cross-sectional area of the housing 2.
  • the street drain 1 has a traffic-resistant, drive-over cover, for example made of cast iron, which partially covers the housing 2. While in principle the entire open front side of the housing 2 can form the inlet of the street drain, the cover (not shown in the drawing) ensures that water, both rainwater directly hitting the street drain 1 and surface water running off the street, flows into the housing 2 exclusively through the coarse filter 5. In this way, in the embodiment shown, the upper edge of the coarse filter 5 forms the inlet through which water can flow into the street drain 1.
  • a traffic-resistant, drive-over cover for example made of cast iron
  • the water flows from the coarse filter 5 onto and into a guide element 6, which is arranged below the coarse filter 5 and runs diagonally downwards to a second outlet 7.
  • the second outlet 7 consists of several individual elements: it has a pipe socket 8 connected by a ball joint and a stepped pipe 9, which changes from the diameter of the pipe socket 8 to a smaller diameter. In the area of this smaller diameter, dotted cutting lines are indicated, which have been introduced into an originally circular pipe cross-section of the stepped pipe 9. In this way, the part of the stepped pipe 9 ending freely in the housing 2 has been processed into a channel, and the end of this channel has been closed with an end wall 10.
  • the guide element 6 also has a groove 11 which has been cut out of a pipe which has a larger diameter than the stepped pipe 9.
  • the gutter 11 therefore projects beyond the reducer 9 on both sides, namely transversely to the plane of the drawing.
  • a reducer 12 indicated by dashed lines is arranged in the gutter 11.
  • the reducer 12 is structurally simple in the form of a flat plate and has a through-opening in its middle region, i.e.
  • a settling basin 14 is indicated in dotted lines, which is located below the step pipe 9 as a component of the second outlet 7.
  • the guide element 6 does not connect watertight to the stepped pipe 9 of the second outlet 7, but rather there are overflow openings between the guide element 6 and the second outlet 7. If, in the case of large quantities of water flowing into the street drain 1, the absorption capacity of the second outlet 7 is exceeded, excess water from the channel 11 of the guide element 6 will flow through these overflow openings into the interior of the housing 2 and onto the floor 3, so that these excess water quantities are led from the street drain 1 into the sewer system through the first outlet 4. The same applies if the absorption capacity of the channel 11 is exceeded: then water portions from the channel 11 will also flow into the interior of the housing 2 and onto the floor 3 without reaching the second outlet 7.
  • the guide element 6 is loosely placed in the street drain 1. Its channel 11 is dimensioned so long that the guide element 6 is aligned at an angle.
  • the guide element 6 is mounted in the street drain 1 in such a way that it is initially positioned with its outlet end - the left, lower end in the drawing - is supported on the stepped pipe 9 of the second outlet 7. The opposite end of the channel 11 is then lowered until the channel 11 rests against the inside of the housing 2, which automatically results in the inclined position of the guide element 6.
  • a flat seal 15 connects to the channel 11, whereby the flat seal 15 is shown purely schematically in a straight line in the drawing. In fact, the flat seal 15 is so large that when it rests against the housing 2, it deforms like a trough to form a sealing apron, which guides water striking the flat seal 15 into the channel 11 of the guide element 6.
  • the channel 11 is open at its outlet end, behind the reducer 12 in the direction of flow, but is closed at its opposite end by means of an end wall 16.
  • the end wall 16 facilitates the assembly of the flat seal 15 on the guide element 6 in that the flat seal 15 can be attached to the upper edge of the end wall 16, e.g. can be screwed or glued to the end wall 16.
  • the flat reducer 12, designed as a plate and provided with a through-opening can also be arranged as an end wall at the end of the channel 11, namely at the lower, left outlet end.
  • the drawing shows the guide element 6 in its working position, with the channel 11 curved downwards and thus open upwards.
  • the channel 11 is covered by a sieve 17, so that particles that have passed through the coarse filter 5 are retained on this sieve 17 and, due to the inclined position of the channel 11, are washed off by water hitting the sieve.
  • the channel 11 can extend further to the left and with its outlet end on the upright running, dotted cutting edge of the step pipe 9, so that the sieve 17 extends over the closed pipe circumference of the step pipe 9. Particles that are washed off the sieve 17 therefore reach the outside of the step pipe 9 and not into the second outlet 7.
  • the guide element 6 has a holding section 18 which, in the illustrated embodiment, is designed in the form of a ring eyelet, so that the guide element 6 can be grasped by means of a shaft hook and removed from the housing 2, provided that the coarse filter 5 has been removed first.
  • the design of the guide element 6 with a channel 11 makes it possible to then turn the guide element 6 around so that the channel 11 is curved upwards.
  • the guide element When the guide element is then reassembled in this orientation, it assumes its rest position, in contrast to its working position described above. In this rest position, it still guides water hitting it from above. However, the water is not guided into the second outlet 7 as in the working position, but the guide element 6 acts like a deflector hood in the rest position and directs the water sideways from the channel 11.
  • the guide element 6 In order to be able to handle the guide element 6 easily even when it is aligned in its rest position, the guide element 6 also has a holding section 18 on the underside shown in the drawing, which forms the top of the guide element 6 in the rest position, which can also be designed as a ring eyelet, for example, but is not shown in the drawing.
