Definitions
- the present invention relates to a rainwater relief system with a rain overflow basin and a retention floor filter.
- the rain overflow basin is used first a so-called partition structure upstream, which a Has collection chamber for water coming from the inlet.
- the water flows out of the collecting chamber in normal operation a line to the rain basin, at the inlet of a throttle or a slide is provided to control the flow to be limited by the line to the maximum allowed.
- the collection chamber has an overflow threshold. Water running over the threshold can then can be derived via a line.
- the problem of finite rain pool volume is at a standstill the technology solved by using the rain basin as a rain overflow basin be designed, during heavy rainfall Collected water runs over a threshold and drains away becomes.
- a receiving water i.e. the natural one intended to discharge the waste water
- Waters to feed the excess can in a rainwater overflow basin rainwater no longer comprehensible due to a so-called Retention floor filters.
- This retention floor filter becomes water from the overflow of the rain overflow basin or fed from the overflow of the separating structure.
- a typical retention filter is in the form of a below e.g. with a suitable seal sealed floor recess educated.
- the normally dry retention soil filter Water which gradually through the acting as a filter Soil seeps into the drainage system.
- the planting of the retention soil filter not only helps to reduce Pollutants, but also loosens the soil. This prevents that the filter through fine-grained suspended matter, etc., the can cause gradual inflation, become clogged.
- the filter effect is generally sufficient for an introduction of the filtered water in the receiving water.
- the retention soil filter only relieves pressure in extreme precipitation directly at most a few times a year in the receiving water.
- the object of the present invention is to create something new to provide for commercial use.
- a basic idea of the present invention is therefore to arrange the individual hydraulic structures relative to each other in such a way that over the overflow water is channelless and pipeless can immediately fall to where its immediate follow-up is guaranteed. It was recognized that this was due to structurally less complex and sometimes even simplifying the construction Changes to the hydraulic structures and their corresponding ones spatial arrangement in a cost-effective manner to save space and is possible while simplifying operations.
- the basic idea of the invention is first embodied by in a rainwater relief system with a rain overflow basin and a retention soil filter in the overflow area a weir threshold is provided, which is directly in the retention floor filter leads. So the overflowing water will not in a pipe behind the rain overflow basin composed, i.e. e.g. channeled and over longer distances Filter fed, but gets directly into this. This saves both the construction of a long retention floor filter supply line and manifold assembly as well as floor space.
- the retention floor filter not as preferred as a bottom recess with below of the ground level, but as approximately formed with an earth wall, can in the inventive installation of overflow basin and retention soil filter the walls of the overflow basin in the immediate vicinity in the inflow area also as a limitation of the retention floor filter serve what lowers construction costs.
- the flow rate of the water flowing into the retention soil filter significantly reduced without known arrangements that the water has to be trickled. This is especially true if the weir threshold width over which the retention floor filter is loaded, more than 5% and in particular approximately 25% of the size of the rainwater overflow basin. It is possible to use the rain overflow basin as a rain cyclone basin to build, in a preferred embodiment the rain cyclone basin generally charged tangentially in the first quadrant and is relieved in the fourth quadrant.
- Relief point in the fourth quadrant can water into one trough-shaped around the storage area of the rain cyclone basin Overflow area of the same and preferably in the second quadrant, i.e. opposite the Overflow or attack relief point.
- a weir threshold width of almost 25% of the circumferential length of the rain overflow basin is obtained when the water is then across the width overflows at least essentially of the entire II. quadrant.
- the arrangement of the one that loads the retention floor filter Overcurrent weirs in the second quadrant allow training of the overflow area as a circulation trough in which the water masses can be divided into two flow paths. This relaxes the inlet conditions in the retention floor filter continue; the risk that through in the retention floor filter masses of water poured in or uprooted the planting is significantly reduced.
- the overflow area is trough-shaped, that is preferred Storage area of the overflow basin by a first relief weir relieved into the trough and a lower one at the trough Overflow weir to the retention floor filter provided.
- the Water therefore flows out of the over two weir thresholds Storage area of the rain overflow basin in the retention soil filter; the second weir threshold in the flow path represents the overflow weir threshold of the Overflow area.
- a sieve arrangement can be provided in front of the retention floor filter become. With trough-shaped formation of the overflow area with two weir thresholds from the storage area to the retention floor filter can in particular in a manner known per se the relief barrier of the storage area is provided be.
- the first with a trough-shaped overflow area and the second weir threshold in the direction along the trough channel from each other are spaced. This prevents gushing Spill over the memory area over the first at the same time and second weir threshold directly into the retention floor filter with potentially adverse effects on planting. Rather, the water is first braked and runs slowly and evenly to the overflow weir threshold and in the retention floor filter. If the first and second weir threshold spaced from each other in the direction along the trough are, the trough bottom preferably has a slope from the first to the second weir threshold.
- a third self-defense is provided in the overflow area, about which extremely large, also from the retention floor filter quantities of water that can no longer be taken in are fed to a receiving water become;
- a retention soil filter is designed so that this is rare and at most with few rain events is required annually.
- very heavy rain events is the water freight after the plant is full but mostly already so little polluted and the receiving water so strong flows through that this does not significantly affect water quality impaired.
- the self-defense is dimensioned that it is when the retention bottom filter accumulation target is reached overflowed without further measures. It's easy for that an appropriate self-defense level is required.
- the rainwater relief system of the present is preferred Invention provided with a storage device, in particular with accumulation boards, which are formed when the overflow area is formed Trough shape can be placed transversely in the trough channel.
- a storage device in particular with accumulation boards, which are formed when the overflow area is formed Trough shape can be placed transversely in the trough channel.
- the stowing device is prevented from Water flows into the retention floor filter, for example when the retention floor filter must be maintained. In such a case the inflow water quantity is simply direct via an emergency drain directed into the receiving water.
- the storage device is also at gradual expansion of rainwater relief systems according to the invention or can be used when retrofitting existing systems.
- the retention floor filter can be directly behind the weir threshold Stones such as grid stones, paving stones or the like. have the surge of water flowing into the filter weaken. Grass pavers are due to their availability and their low price particularly preferred.
- the retention floor filter itself can also have an overflow threshold, i.e. an overflow weir, which directly or indirectly leads to the receiving water to make the water very large To derive precipitation.
- an overflow threshold i.e. an overflow weir
- the retention floor filter can also be used an earth wall raised from excavated earth or the like be surrounded to make the retention floor filter a larger one Arrange stowage area without actual filtering. So can far larger amounts of water are absorbed than with the actual one Retention floor filter possible.
- the retention floor filter subordinate stowage area does not have to for Water filtering must be designed, so no drainage system, none Have planting, etc. Rather, the traffic jam area if the water load declines via the retention soil filter empty by returning the water.
- the actual Retention bottom filter can, as is generally preferred, as Be deepened so that its storage target on or is slightly below the normal floor level.
- the retention floor filter can drain as needed be pumped dry via the drainage system, in particular using a solar-powered feed pump. This can be used since the retention soil filter after a precipitation does not have to be dried out instantaneously, but the draining completely sufficient within a few days; out of this Weak feed pumps can be reasonably reduced with accordingly Power requirements are used.
- the drainage of the drainage system is in the rainwater relief system preferably controllable. So through drainage or throttling at the beginning of precipitation even with low Evenly deposit the retention soil filter with water covered and the infiltration is not exclusively concentrated on the inlet area near the weir threshold. A uneven loading of the filter with a corresponding uneven sediment piling is avoided by at least the entire pore space of the filter is jammed, i.e. completely moistened or covered the floor surface becomes. It is preferred to hold it until the water in the Retention space has reached a height of a few centimeters. This will also help the growth of unwanted plants prevented that are entered in the filter and typical are not water loving.
- a rain cyclone basin with a central supply shaft can be used as a rain overflow basin, in particular the accumulation arrangement, the feed pump, when forming the circulation area a trough-clear water rinsing supply as overflow trough etc. as essential control and / or regulating devices and - systems can be accommodated in the central shaft. This is preferred the water from the retention filter with a Culvert under the rain overflow basin into the central shaft and led out of this.
- a rainwater relief system 1 or Rain relief system 1 a rain overflow basin 2 and a retention floor filter 3.
- the rain overflow basin 2 has a general tangential feed channel 4 for the supply of mixed waste water or, in the case of separation systems, rainwater from settlements and the like.
- a drainage channel 5 with a pipeline 6 provided, which to a sewage treatment plant, another rain overflow basin or the like. Preference is given to a swirl throttle 6a leading to the sewage treatment plant 6 or the like.
- the rain overflow basin 2 has an inner edge 7 which with the exception of a relief barrier 8 on the whole Circumference has the same height and thus an inner storage area 2a of the rain overflow basin 2 defined.
- the relief barrier 8 is preferably removed in terms of flow arranged from the inlet. In the arrangement shown in Figure 1 with incoming in the first quadrant and clockwise circulating water (as indicated by arrow 10) the relief weir threshold 8 in the fourth quadrant.
- the relief weir threshold 8 relieves the inner storage area 2a of the rain cyclone basin 2 into a trough-shaped Overflow area 9, which is formed here as a circulation trough. Its outer wall 11 is generally full over its entire circumference the same height, which can be as high as the height of the rain cyclone basin. On the relief weir 8 diametrically opposite Side ( Figure 1) is the outer wall 11 of the Overflow area 9, however, lowered to an overflow weir threshold 12 to form, which directly in the directly subsequent inflow region 13 of the retention floor filter 3 leads.
- the width of the overcurrent weir threshold 12 is preferred large; it can do at least a substantial fraction of a quadrant comprise or, preferably, the entire quadrant. Larger weir threshold widths are possible as long as hydraulically perfect functioning is guaranteed; at Lengths over 25 or 30 m, such as occur when one Weir threshold width of two quadrants can be selected Weir threshold designed horizontally adjustable as required become.
- the retention floor filter 3 can, preferably immediately behind the overflow weir threshold 12 large stones, pavement, or in particular grass pavers 14 in the surge path of the Overflow water can be arranged.
- Overflow weir threshold 12 lead through the circumferential overflow area 9 two flow paths 15a and 15b from the first to the second weir threshold.
- the trough bottom 16 has in each Flow path 15a, 15b a downhill to the overflow weir threshold 12 Slope on, as by the dashed line in Figure 2 indicated.
- a stowing device 17a, 17b can be arranged, for example can be realized by storage boards or the like can to establish a water connection between the relief weir 8 and the overflow weir 12 to interrupt.
- Self-defense threshold along at least one flow path 15a, 15b 18 provided in the outer wall 11 of the overflow trough, which connects the overflow area with an emergency drain 19, which leads to the receiving water, for example.
- the high of Self-defense threshold i.e. the emergency relief threshold, corresponds preferably the retention target height of the retention floor filter, so that the water in the emergency drain without further measures flows when the congestion target is reached.
- the retention floor filter 3 is a depression formed, which is adjacent to the circulation trough 9 of the rain cyclone basin 2.
- the excavation 20 of the recess 21 can also a wall around the retention floor filter an enlarged storage area around the retention floor filter to define around.
- the overflow weir threshold preferably above ground, but below the top of the rampart lie.
- a seal 23 is stacked on the natural base 22 from geomembranes, mineral waterproofing or the like, e.g. drainage embedding layer constructed as a gravel bed 27 with drainage pipes 28 running therein and, over this layer, several filter layers 29a, 29b, on and in which plants 30 grow, as preferred Reed.
- the retention floor filter 3 may be up to one Height to be accumulated, dashed as the traffic jam line 31 is drawn. If the retention filter with a Earth wall is surrounded, the traffic jam line is above the ground lie.
- the rainwater discharge system of the present invention is operated as follows:
- the rainwater relief system thus works in light rainfall as a purely temporary store, which the large amounts of water, such as they occur in the event of precipitation until they are clarified.
- the water in the rain overflow basin keeps getting bigger rise until the water level reaches the level of the relief barrier 8 has reached. As soon as this is the case, it flows Water from the storage area into the trough-shaped circulation area 9 along the slope 16 to the diametrically opposite Page. So water collects in the circulation trough and the water level rises here too.
- the overflow weir 12 is so wide that the water is slow and flows evenly into the retention floor filter 3; also will that in the retention floor filter 3 over the weir barrier 12a flowing water in one during extreme rains nevertheless gushing and undesirably violent movement slowed down by the grass pavers 14. That way prevents that falling into the retention floor filter 3 Water lying in a direct flow line Plants 30 can outline and so at these points Filters impaired or destroyed.
- the retention soil filter will change 3 continue to fill until finally the water level has reached the height of the traffic jam line 31.
- the size of the retention floor filter is typically chosen so is that such a situation is rare, if possible only occurs a few times a year.
- the water level has one in such a case, however, the self-defense threshold has already been reached; therefore there can be no further overflow of water in the retention floor filter 3, because the water is be discharged via the self-defense 18. It can be provided In these rare cases, supply water directly to the receiving water. Since this only happens during very heavy rainfall, is not a significant impairment of the water quality to fear.
- Such a supply of water the rain overflow basin in the receiving water or the like otherwise also be provided if, for example, the retention floor filter must be maintained or in other exceptional situations.
- the accumulation tables are in the circulation trough introduced the water directly into the emergency drain pipe without filling the retention floor filter.
- plants 30 collect the retention soil filter 3 can prevent the relief weir 8, in the trough 9 or screens 32a, 32b are also provided on the overflow weir threshold 12 in order to feed coarse material into the Decrease filter.
- the retention floor filter can also be used, preferably on another side facing away from the rain overflow basin 2
- Weir 33 have an emergency overflow, over which very violent Rain events can cause water to flow into the receiving water.
- the accumulation plates 17a, 17b do not have to go into the circulation trough be inserted, but the water overflows the length of the retention floor filter up to self-defense 33 of the retention soil filter and from there into the receiving water.
- the rainwater relief system of present invention not only for the absorption of rainwater, but also for temporary storage and treatment any other precipitation, including hail, snow, as well spring water, etc., is suitable.
- the central shaft 35 is according to the figure 4 divided into several areas, namely on the one hand in one Cyclone basin drain area 36a and on the other hand in the retention floor filter drain area 36b.
- the cyclone pool drain area 36a is with the storage area 2a of the rainwater overflow basin via a mechanical or electrically operable slide 37 and a feed line 38 connected and empties the rain overflow basin via a vortex throttle 6a or the like in a discharge channel to a sewage treatment plant or another, downstream rain overflow basin.
- the retention floor filter waste water area 36b in the central shaft is divided into two chambers, namely an entry chamber 39 and into an outlet chamber 42, between which a connecting pipe 43 is arranged.
- Water from the drainage network 28 is introduced into the inlet chamber 39 guided, the outlet piece 44 of the drainage network 28 T-shaped is formed.
- One arm 44b of the T-piece is in one Height C above the floor of the entrance chamber (height A) horizontal led into the chamber and usually with one Slider 45a closed.
- the other arm 44a of the tee protrudes into the chamber and has an opening 46 at height E.

- the pressure side of the flushing pump 47 is on a line 50 is connected, which leads into the trough channel 9.
- the irrigation pump 47 has sufficient power to the circulation trough 9 rinse as required after a rain event; the inlet chamber 39 thus also serves as a reservoir for sufficiently clean rinse water, i.e. as rinsing chamber 39. From the inlet chamber 39 can also water for filter control be removed.
- the inlet chamber also has a water level probe as required (not shown) for control purposes.
- the entry chamber 39 communicates via a connecting pipe 43 with the outlet chamber 42.
- the connecting pipe 43 is one Sequence control 51 arranged that the water flow in dependence throttle from the water level and / or preferably entirely can lock.
- the bottom passage edge of the connecting pipe 43 lies at a height F corresponding to the height F of the drainage system 28 or a bit below and thus on or below the level of the pore space lower edge of the retention floor filter 3rd
- a sump is formed in the outlet chamber 42, which is up to a height D below the mouth height F of the connecting pipe 43 is lowered.
- the swamp is initially parallel with one pipeline 50 going down to the central shaft wall provided that has a T-piece at its lower end.
- a Arm of the T-piece is led through the wall to the entry chamber and at height C with a normally closed one Provide slider 45b.
- the other arm is with a drain pipe connected that runs under the rainwater overflow basin to outside of the rain overflow basin area at a height G in a drain to the receiving water or the like.
- the mouth height G of pipeline 50 is optionally above the pore space, ie above height F, so that at least from the lower edge of the pore space water not without support can get into the receiving water.
- the suction line 52 projects into the sump of the outlet chamber 42 a drainage pump 53 protrudes.
- a drainage line 54 with preferably small diameter of e.g. 2 inches provided leads to a discharge to the receiving water.
- a drainage pump 53 is smaller Pumping power is sufficient and will be completely satisfactory Results.
- a drainage pump 53 with small Pumping rates such as 0.1 liters / second can be problem-free be fed with solar power, so that when building the Rainwater discharge system removed from the mains on one expensive and complex power connection dispensed with can be.
- solar power so that when building the Rainwater discharge system removed from the mains on one expensive and complex power connection dispensed with can be.
- the pumping power as with solar power operated pumps are achievable, it is generally required be to provide a surge flush in which a volume of water is slowly being filled up again and then emptied into the gutter like gushes.
- a single solar powered pump could be provided which can be selected via a three-way water valve steadily filling and periodically draining trough gutter flushing or a drainage line 50 supplies and if necessary at various points in the central shaft 35 sucks in water.
- the overflow area 9 of the rain cyclone basin according to FIG. 3 differs from that of the rain cyclone basin according to FIG. 2 further in that on the inner wall of the trough opposite the overflow weir 12 a residual water emptying flap 55 is arranged on the trough bottom is. This is articulated on its lower edge 55a and has a float 55b on its upper edge.
- a lock 54c locks the residual emptying flap 55 watertight wall 7 of the rain cyclone basin.
- the lock is 55c manually or automatically on mechanical or electromagnetic Unlockable way.
- the self defense 56 with a height N is lower than the relief barrier 8a with height O, but higher than the overflow weir threshold 12a with height M and can in particular with the congestion target reached water level N.
- the rainwater relief system with the rain overflow basin 3 operates as follows:
- the water flowing into the retention soil filter 3 seeps first enters the inflow area and enters the drainage network and flows through opening 46 into the entry chamber where an Water rise is detected with the water level probe.
- the retention floor filter sequence control closes at the beginning Overflow of the overflow weir 12 first the connecting pipe 43 so that no water from the inlet chamber 39 can drain and the water both in the inlet chamber 39 as well as increases in the retention floor filter 3. This continues until the filter base is jammed, thus preventing one Excessive filter load in the entry area of the retention floor filter through water seeping only there.
- Optional can also delay the release of the connecting pipe 43 until the water is a few inches above the filter bottom stands (height J), at the same time the growth registered Encounter plants.
- the water drain in Connection pipe 43 released for a desired water flow. If necessary, one can be used for a desired filter throughput required throttling can be made.
- the retention floor filter drains 3 at least partially via its drainage system 28, the inlet chamber 39 of the central shaft 35, the Connection pipe 43, the outlet chamber 42 and the pipeline 50 to drain into the receiving water. At the same time, water can be used for testing purposes be removed or pumped out.
- the water level in the retention soil filter 3 gradually increases lose weight. This process continues until the water level has dropped to the mouth height G of the pipeline 50. To active drainage is not required at this level.
- the retention floor filter 3 is completely empty or dry falls. This is how the full one for the next loading event Retention floor filter absorption capacity restored and ensures re-ventilation.
- water can be flushed with the irrigation pump 47 can be introduced into the trough to any existing or remaining deposits after unlocking the residual water emptying flap 55 from the trough into the rain cyclone basin storage area 2a wash out.
- the water turns on a point well above the floor, about height E to avoid sucking in sludge.
- This Type of cleaning is particularly advantageous because it is used for rinsing the filtered water is used. That with contaminants Water loaded from the trough channel 9 comes with the residual water through the residual emptying flap 54 into the storage area 2a of the rain overflow basin 2, from where it goes through the pipeline 6 reached the sewage treatment plant.
- the drain chamber By the outgoing culvert branch into the already deepened inlet chamber the drain chamber must be built less deep and is easier to walk on.
- a rain overflow basin 2 has a central one Rain overflow basin storage area 2a, which has a relief threshold 8 into a trough-shaped overflow area 9 is relieved with outer trough wall 11, on which water over an overflow weir threshold 12 into a retention soil filter 3 flows in, stones 14 arranged in the inflow region are integral to a dividing structure 60 for reduction in the central storage area 2a of the rain overflow basin 2 flowing water inflow to a given maximum amount to limit.
- the separating structure formed integrally with the rain pool 2 60 communicates via a running below the trough 9 Connection 61 with the supply duct or supply pipe 4.
- the connection 61 leads on the one hand via a Throttle 62 is approximately tangential as is generally the case in the prior art known in the rain overflow basin formed as a rain cyclone basin 2.
- the connecting line is via a riser line 63 61 connected to a side chamber 65 upwards, which in Trough 9 is separated by walls 64a, 64b, 64d and 64e.
- the Walls 64a to 64d have the same height as the outer edge of the trough 11 while the concentric between inner and outer Trough wall extending partition 64e is designed lower.
- the bottom of the separator chamber 65 is preferably for the riser 63 downhill to complete emptying in precipitation-free Ensure times.
- the partition 64e preferably has a height which is greater than the height the discharge defense threshold 8 and thus also higher than that Overflow weir threshold 12 (see FIG. 8).
- the rainwater relief system with the rain overflow basin and the integrated separator is operated as follows:
- Water is throttled via supply line 4 and connecting line 61 Way into the central rainwater overflow basin storage area 2a headed.
- the throttle 62 is on this set the desired flow.
- the inflow 4, 61 communicates here via the riser 63 with the side chamber 65 in the trough area 9.
- a small reservoir is first filled when the on the throttle 62 set amount of water is not sufficient to let all water flowing in through supply line 4 pass through. If the side chamber 65 is filled, water is on the lower partition 64e fall into the trough area 9 and from there into the retention floor filter over the overflow weir threshold 12 and this stones 14 downstream in the direction of flow flow. On this ensures that in normal operation with low water pollution all water through the rain overflow basin can flow into the sewage treatment plant through line 6.
- the relief weir 8 as well as the separator threshold a diving wall 8a, which is on the water 57 floating light materials 58 such as gasoline prevents in the To reach overflow trough 9, cf. Fig. 5. Accordingly the lower partition 64e may also be formed.
- the overflow weir does not necessarily have to be as shown Overflow weir lie above the filter base, but can be about finish flush with this. If in such a case the Overflow area as a circulation trough with a relief weir above of the filter base, it may be preferred shooting the water into the retention filter Limit stones, tablets or the like.
- the rain overflow basin in the To be placed in the middle of the retention floor filter and not at the edge. In this case, particularly wide overflow weirs can be implemented become.
- any other geometric shapes for the pools are possible. So instead of round pools are polygonal, for example square Usable basin on the long side of the retention floor filter are arranged and preferably in this one overflow very wide weir threshold.
- the realization such a wide weir threshold has a further reduction the swell strength results in a better one Energy distribution of the inflowing water.
- a weir threshold that can be adjusted horizontally used to be particularly long Weir thresholds, like over 30m, one across the entire width provide a uniform overflow.
- the width of the overflow weir about a quarter of the overflow circumference are smaller widths, such as only 5 or 10% of the scope can be easily realized, if through appropriate measures such as grass pavers, the are available particularly easily and inexpensively, near the overflow weir threshold excessive penetration is prevented.
- overflow weir Unlike shown, it would also be conceivable to use the overflow weir to make it wider than a quadrant and for example to run half the overflow basin circumference.
- the rainwater overflow basin can in particular if training as a rain cyclone basin also without rearrangement a retention floor filter with an integral separator be provided.
- the connection of rain overflow basins and separator is not to the specific embodiment shown of the round rain overflow basin, but can also be realized with any other rain overflow basin corresponding to a rain overflow basin with a central shaft Figure 3.
