Definitions

  • the present invention relates to a Filterubstratrinnenelement for discharging and cleaning of surface water, comprising at least one channel body with a arranged in this gutter body filter substrate and arranged below the filter substrate drainage chamber, which is closed on the underside of a, at least partially permeable to water, gutter bottom of the gutter body.
  • Troughs for surface drainage of this type have been known for some time in the prior art.
  • the EP 2 080 840 B1 a Filterubstratrinne, in which a drainage chamber is formed by a permeable, inserted into a gutter body filter tube.
  • the incoming water into the channel body is then first cleaned by the filter substrate surrounding the filter tube and then runs more or less from all sides into the filter tube, which forwards the water over the side edges or the front side of the channel body.
  • a similar solution sees the DE 10 2012 001 574 A1 before, in which a filter cartridge is used, which practically encloses the filter substrate.
  • the filter insert forms a drainage space with the gutter body and can be removed completely as an insert with the filter substrate.
  • the incoming water penetrates the outer wall of the filter insert, passes through the filter substrate located therein and exits from the filter insert on the underside in the direction of the drainage space.
  • an elaborate coarse filter is additionally used.
  • a filter substrate element for discharging and cleaning of surface water is previously known, in which the incoming surface water first enters an inlet space in which a filter substrate is arranged, which then passes into a arranged below the inlet space drainage space, which is separated by an intermediate level of the inlet space is.
  • this filter substrate element is not channel-shaped.
  • Another problem of prior art dewatering troughs provided with a filter substrate is that the filter element, which is usually formed by a filter substrate, allows a slower passage of water than a dewatering trough that does not have such a filter substrate is provided. This is because the introduced surface water, while penetrating the substrate, is purposely cleaned and thus has a longer residence time in the filter substrate than if it were discharged unfiltered by a groove member. This disadvantage is accepted, because in this way a first cleaning of the introduced surface water is effected.
  • the invention is therefore also based on the object of developing a solution for the previously known filter substrate inner elements which, at least as required, in the case of heavy rainfall events, for example, has a higher absorption capacity.
  • the solution of this object is achieved according to claim 1, characterized in that in the gutter body, a drain pipe is integrated, the inlet is disposed above the filter substrate and thus allows passage of the introduced surface water through the drain pipe, bypassing the filter substrate to an outlet of the drain pipe.
  • a drain pipe is integrated, the inlet is disposed above the filter substrate and thus allows passage of the introduced surface water through the drain pipe, bypassing the filter substrate to an outlet of the drain pipe.
  • the drainpipe thus has the function of preventing overflow of the filter substrate inside element, because possibly over a critical water level rising surface water within the gutter body can flow unhindered through the drain pipe and thus prevents the water level within the gutter body rises above this critical height.
  • this solution also increases the swallowing capacity of the gutter.
  • the advantages of the filter substrate inner element according to the invention are not exhausted in an overflow protection of the corresponding channel, but rather allows the above-described partial flow treatment using the drain pipe according to the invention a calculation of the proportion of filtered and unfiltered derived surface water in relation to the expected introduced total surface water amount.
  • the hydraulic power of the gutter system can be adjusted in dependence on these calculations.
  • the hydraulic power or the drainage capacity of the gutter system depends on the respective nominal diameter or the inlet cross section, the backwater depth and the discharge cross section of the gutter used in each case.
  • the rate of flow through the filter substrate affects the drainage capacity of the gutter system.
  • this flow rate reduces the drainage capacity so that backflow can occur at higher discharge rates and not all filtered surface water can be filtered immediately. It can therefore only a part of the discharge flow filtered in this case and the other part are discharged directly through the drain pipe.
  • the filtered discharge rate and the unfiltered discharge rate can be accurately determined based on the parameters of the flow rate of the filter substrate used, the backflow potential in the gutter line and the drainage capacity of the drain nozzle or the drain pipe. Due to the variability of the backwater depth and the cross section of the gutter system used, it is possible to precisely calculate and thus also plan how the division of the filtered and unfiltered portion of the introduced surface water should take place for the respective drainage gutter system.
  • the filter substrate inner element according to the invention thus offers the additional advantage that both the hydraulic capacity as well as the respectively required filter degree of the introduced surface water can be precisely adjusted as a function of the expected amount of rainfall.
  • the Filterubstratrinnenelement can therefore to the respective requirements be precisely adjusted on site or optimally adapted to them.
  • both the inlet and the outlet of the drainage pipe can be arranged above the filter substrate arranged in the gutter body. This causes a relatively high-lying connection for the outgoing from the gutter body surface water, which allows a variety of different connection options, in particular the connection to common sewer or drainage pipes.
  • the outlet of the drainage pipe can also be arranged below the filter substrate integrated in the channel body, with the result that both the filtered and the unfiltered surface water optionally emerge from the drainage space of the channel body through the groove bottom permeable to water, at least through a common outlet.
  • a two-part gutter twine can be used instead of a single gutter body.
  • the second channel body is in this case closed by the first channel body such that the channel bottom is placed on the second channel body.
  • the surface water entering the first channel body passes through the filter substrate arranged on the bottom of the first channel body and will enter the second channel body through bottom-side openings of the first channel body.
  • the channel bottom of the first channel body is to make at least partially permeable to water, in particular to provide openings.
  • Such openings may in this case be closed with a filter grid, which is permeable to water, but impenetrable to the filter substrate itself, so that the filter substrate is prevented from falling into the second channel body.
  • the individual elements are formed such that the channel bottom of the first channel body can be connected to the receptacle of the channel cover of the second channel body.
  • the inclusion of the gutter cover of the second gutter body would be used in the usual installation to attach a cover on the gutter, for example in the form of a cover grating.
  • the same receptacle of the channel cover can also be used in the installation according to the invention to hold the channel bottom of the overlying first channel body so that a defined position with respect to the two channels is formed. In this case, it is irrelevant whether the first channel body has a larger or smaller nominal diameter or, preferably, has the same nominal diameter as the second channel body.
  • the underside of the channel body is formed closed, so that any connection adapter can be omitted.
  • the connection is then simply by riveting or screwing, or if necessary, by bonding.
  • the openings in the bottom region are preferably round and, as already explained, provided with an effective filter grid, so that no filter substrate can penetrate into the second channel body.
  • the number and size of openings is calculated based on the filter performance of the system.
  • the backflow volume in the filter substrate channel also plays an important role here. High backflow volume acts as an intermediate buffer for wastewater. For the accumulated filtered water, it may even be sufficient to select a smaller or smaller in volume or second gutter body unit.
  • Filterubstratrinnenelements can be created by additional use of a filter mat or filter plate in the bottom region of the first channel body, an additional reservoir in the outflow. This effectively increases the drainage performance of the assembly.
  • the filter substrate inner elements have with some advantage in the region of the second channel body at least one side outlet, via which the resulting, filtered surface water can be removed.
  • Such horizontal connection options are an important advantage, since a connectability in different directions is guaranteed.
  • the connections advantageously provide a connection with common sewer or drainage pipes.
  • an outlet pipe can advantageously also be integrated in conjunction with a two-part gutter body in such a way that a drainage pipe is arranged in the inlet space in order to be able to discharge surface water which accumulates suddenly to a great extent.
  • a drain pipe is in this case perpendicular to erected the first gutter body and has an inlet in the amount of the maximum filling height of the gutter body.
  • the drain pipe can in this case open directly into the drainage chamber, so that in this way, in the event of an emergency overflow, the unfiltered water can be mixed with the filtered water in the drainage space and discharged therefrom.
  • the vertically upright drainage pipe can be discharged via a side drain of the first channel body and in this case either forwarded separately or be fed outside the Filterubstratrinnenelements via a merger together with the filtered water from the drainage space of the sewer.
  • FIG. 1 shows a one-piece channel body 20 in a cross-sectional view.
  • This channel body 20 is closed on the upper side by a receptacle 8, in which a channel cover 15 is inserted.
  • a filter substrate 6 is introduced, which is closed on the underside by a filter grid 10, which can also be provided with a fine flow, with respect to an arranged below the filter substrate 6 drain chamber 5.
  • the gutter body 20 has in the region of the gutter bed a drain neck 9, from which in the gutter body 20 through the gutter cover 8 introduced surface water flows out, or in a - not shown here - downstream sewer is initiated.
  • this drain pipe 13 As shown in FIG. 1 is in this one-piece channel body 20, a drain pipe 13 incorporated, this drain pipe 13 has a straight course and passes through the arranged in the lower region of the channel body 20 filter substrate 6 passes, so that the outlet 22 of the drain pipe 13 below the filter substrate 6 in the drain chamber 5 opens.
  • both the unfiltered, passing through the drain pipe 13 surface water, as well as the filtered through the filter substrate 6 and filtered surface water enters the drain chamber 5, and then finally discharged through the geodetically deeper outlet nozzle 9.
  • filtered and unfiltered surface water such as in the case of heavy rain, mixed in the drain chamber 5, wherein due to the filtering effect of the filter substrate 6 and the associated supply of partially purified water still a better water quality is guaranteed than when completely unpurified water , for example, in heavy rain, would enter the connected sewer.
  • FIG. 2 shows in a cross-sectional view of a filter substrate inner element 1, substantially comprising a one-piece channel body 20, in the lower region of a filter substrate 6 is arranged.
  • an inlet space 4 is formed above the filter substrate 6 arranged in the lower region of the channel body 20 within the channel body 20, while an outlet space 5 is formed below the filter substrate 6.
  • the filter substrate 6 is separated from the underside of a filter grid 10 with respect to the discharge space 5.
  • a discharge nozzle 9 is formed from the surface water penetrated into the discharge chamber 5 can escape after passing through the filter substrate 6 and the filter grid 10 from the channel body 20 in an approximately connected sewer.
  • Upper side is the gutter body 20 of a receptacle 8, so as a frame, completed in the in the illustration according to FIG. 1 a gutter cover 15 rests.
  • the drain pipe 13 has an inlet 21 in its upper mouth region, wherein the inlet 21 is arranged below the gutter cover 15, but above a predetermined critical filling level of the gutter body 20.
  • the drain pipe 13 is led out laterally out of the channel body 20 and ends in an outlet 22 which is arranged below the inlet 21 but still above the upper edge of the filter substrate 6.
  • Separate drain lines can be connected to the side outlet of the drain pipe 13, which is thus comparatively highly arranged in the installation situation, from which unfiltered water flows out in the event of heavy rainfalls by means of the partial flow treatment. In this regard, the comparatively highly arranged outlet is advantageous.
  • FIG. 3 shows a Filterubstratrinnenelement 1, consisting of a first channel body 2 and a second channel body 3.
  • the first channel body 2 is in this case arranged above the second channel body 3, such that in the channel bottom 7 of the first channel body 2 recessed outlet nozzle 9 open into the second channel body 3 , About side drains 14 and 12, the arrangement of drain pipes or overflow pipes usual nominal width is possible.
  • a drain pipe 13 is shown with a side drain 14. This results in several options for the further use of surface water.
  • the drain pipe 13 can be connected as an emergency overflow in case of heavy rainfall directly on the side drain 14 to the sewer. Only water which flows off via the side drain 12 of the second channel body 3 connected to a percolation is then filtered. In terms of partial flow treatment but also both side drains 12 and 14 can be connected to the sewer.
  • the drain pipe 13 has a free upper edge, which is arranged at the level of the maximum filling of the first channel body 2. If the water level in the first channel body 2 exceeds the upper edge of the discharge pipe 13, the water will flow into the discharge pipe 13 and be discharged via the side discharge 14.
  • the discharge capacity of the filtered surface water, the backflow capacity in the inlet space 4 and the discharge capacity of the discharge pipe 13 it is now possible to calculate the total discharge capacity of the filter substrate system. Over the free upper edge of the drain pipe 13, the total discharge capacity can be controlled. The deeper the drain pipe 13 is arranged in the drain space 4, the more is derived directly unfiltered. Conversely, with greater height of the discharge pipe 13 in the exhaust air chamber 4 more filtered surface water is derived.
  • both side drains 12 and 14 are bundled outside the filter substrate channel via a junction 16 in a duct.
  • FIG. 6 another alternative of an overflow solution is shown.
  • the water in the inlet space 4 enters directly into the drain pipe 13 and spent without detours in the drain chamber 5 in this configuration.
  • a filter substrate inner element or a filter substrate inner system which, in contrast to the prior art, permits a significantly simplified installation at the construction site and a more favorable maintenance.
  • By eliminating the use of additional parts such as filter tubes, filter element carriers and prefilter boxes in the first channel body is not only the installation of a filter substrate channel much easier and cheaper, but it also creates more volume for the filter substrate. This means that the nominal width of the substrate channel can also be reduced. That's another significant cost savings.
  • the multi-storey gutter is installed on site as a normal drainage channel, filled the filter substrate to the predetermined height and made the connections to the underlying, second gutter body. This makes the system functional.
