Definitions
- the present invention relates to an infiltration channel system, especially for the drainage of partially sealed and sealed surfaces.
- DE 44 03 454 C1 is a molded block for an infiltration channel known according to the preamble of claim 1 and 5.
- This molded block consists of a U open at the top, which acts as an inlet area.
- a biological seepage body is provided in the inlet area, who has the task of biologically cleaning the incoming water.
- This gutter is the infiltration performance is low and the infiltration area can relatively quickly below the concrete profile clog.
- differences in the water supply over the length of the Channel difficult to compensate, which is why such a channel in overloaded Areas flooded relatively quickly.
- the aim of the present invention is to avoid these disadvantages and to create an infiltration channel system that is easy to maintain and the risk of soil subsidence decreased.
- a gutter part that is open towards the bottom is a requirement together, the surface water is supplied.
- Under the Cavity is the percolation area, the one Fill, possibly with a certain grain size distribution, which hinders clogging by fines and, if necessary supports the accumulation of bioflor.
- the cavity of the channel part is in the infiltration area the accumulation of aerobic bacteria possible, so that a kind of biological cleaning like in the natural topsoil (Humus) takes place, is buried underground. To this Wise particles and even pollutants can be caused by the bioflor be bound, causing clogging of the infiltration area counteracts and surrounding ground area and even to a biological partial clarification of the infiltration water can.
- the infiltration area can be from the cavity through a geotextile be separated what the entry of fines in hindered the infiltration area and also the installation of Can promote bioflor.
- a geotextile For pressure / suction rinsing of the geotextile in the As part of maintenance, it is advantageous if the geotextile on one or both sides with a sieve or grid-like reinforcement is provided to damage the geotextile when Avoid rinsing.
- the cavity should also be accessible from at least one end face.
- the the water is either over a gutter top or over a cistern, gully or other Surface drainage system (e.g. gutter) fed.
- the geotextile can possibly be exchangeable in the gutter, e.g.
- a drainage channel of this system has one Channel upper part, in which the water from the sealed or partially sealed surface and a downward facing Channel lower part with a cavity into which surface water, e.g. from the gutter upper part over arranged in between Bushings or at the front via a sink box or a Cistern or other water storage or treatment facility is initiated. That in the downward open Water flowing into the cavity of the lower part of the channel seeps away then into the infiltration area in the floor under the gutter lower part.
- the infiltration area can pass through Protect a rodent and backwash-proof fabric.
- the Mouth of the passage in the upper part of the gutter is from the floor of the watercourse in the gutter upper part, i.e. the The mouth of the execution lies in a higher area of the Watercourse and thus acts as an overflow for the watercourse.
- the running into the gutter top Dirt accumulates on the bottom of the watercourse and only that cleaner water through the bushings in the ones below Gutter lower part flows. Clogging of the bushings between the upper part of the gutter and the lower part of the gutter largely excluded.
- Drainage pipes offer compared to the known systems Drainage pipes have the advantage that the drainage system in one operation is laid together with the drainage line. It can even be retrofitted in the area partially sealed surfaces.
- the laying can be independent from the sewer system. The laying does not have to in the form of continuous continuous drainage lines.
- the channels can be arranged individually, which one great scope in the design of a partially sealed Area leaves. The laying can also be done without a slope.
- the infiltration channel preferably consists of two each other facing away, i.e. with their horizontal legs against each other adjacent U profiles, with the U profile open at the top the gutter top and the one below it towards the bottom open U-profile forms the gutter lower part.
- the gutter tops and gutter bottoms In the contiguous Area are the gutter tops and gutter bottoms somewhat broadened, so that on the one hand a larger contact area and on the other hand a widening on both sides of the channel in the transition area arises for the lower gutter Load distribution and for the upper channel as a float protection serves.
- the water course in the gutter upper part is preferably asymmetrical, i.e. offset to a lateral vertical channel wall, while carrying on towards the estuary the other channel wall is offset.
- This enables the arrangement the mouth of the implementation in an ascending Area of watercourse.
- the mouth is now off the ground spaced apart from the watercourse so that it fits into the gutter upper part collects incoming dirt on the bottom of the watercourse, while performing the estuary as an overflow for the watercourse serves.
- the bushings are adjacent to each other Part of the two identical U-profiles drilled in a circle, so that there is a possible axial or lateral offset the gutter does not affect that the water is on the edges created at the transition e.g. by getting caught of debris entering.
- the enlarged, preferably circular cylindrical transition in the implementation ensures that even with a small offset of the gutter top a trouble-free water flow to the lower part of the channel guaranteed between gutter upper part and lower gutter part is.
- the profiles for the gutter top and gutter bottom become - independent whether they are identical - preferably made of concrete block.
- a two-part infiltration channel has the Advantage that the transport and installation of the gutter on site be made much easier.
- one-piece gutter which is an upper upward open section and one below, down open section.
- Such a drainage channel is designed like an "H". A higher infiltration performance you get when the width of the gutter base exceeds the width of the gutter top. To this The cavity and the infiltration area are below the gutter is larger than that defined by the gutter upper part Infeed area of the infiltration channel. This increases the infiltration capacity the gutter.
- the water supply from the gutter top to the gutter bottom can - as already described - by vertical bushings can be realized that the horizontal separation area between push through the gutter top and the gutter bottom. It can however, alternatively or additionally on an end face A sinkhole or cistern at the end of a drainage channel can be provided, which the incoming into the gutter upper part Absorbs water and passes it on to the lower part of the gutter. In one in such a case, the mouth area of the lower part of the gutter should spaced into the sink box from the bottom of the sink box his. In this way the sink box or cistern functions as a sedimentation basin, in which coarse dirt collects.
- the sink box and / or the cistern can be an oil separator be provided, which also slightly polluted the infiltration Allows surface water.
- a cistern or A sink can also be used for storage or water treatment plants be provided in which in the gutter top incoming water is passed.
- the activity of the gutter top can thus time from the activity of the gutter lower part be decoupled. It is still possible to use the upper part of the gutter and the lower part of the gutter to be used separately, which greatly expands the application options.
- the estuary the lower part of the gutter in the sink box then works for the Sink box as an overflow, into which estuary thus only relative clean water enters. In this way, pollution can be avoided or a clogging of the gutter lower part largely exclude.
- a vertical end wall is inserted in the sink box, which extends from the bottom of the watercourse to a certain height extends so that the accumulates at the bottom of the watercourse Dirt is not passed into the gully. So double filtering of coarse particles is achieved before Entry into the gutter lower part.
- the use of a sink box or a cistern continues the advantage that the gutter lower part or in the Channel formed in the lower part of the channel accessible from one end is easy to maintain.
- the gully or the cistern can of course also be used for drainage other areas are used, e.g. for roof drainage.
- the cistern or the gully can continue be provided with an overflow into the sewage system leads.
- FIG. 1 shows an infiltration channel system 10 with a two-part system Infiltration channel 12, consisting of an upper channel part 14 and a gutter lower part 16.
- gutter upper part 14 and Gutter lower part 16 are made of a concrete block as an identical profile educated.
- Both U-profiles 14, 16 lie with their horizontal leg 15 together, which horizontal leg 15 the separation between the inlet area 18 and the after Form at the bottom open cavity 20 of the infiltration channel 12.
- the adjacent floor 17 points in the longitudinal direction of the groove a rectangular toothing, with a floating of the Pre-mixed mortar layer in the resulting cavities prevented and a toothing between the upper part of the channel and the lower part of the channel is achieved.
- a Triangle or sine teeth can be used.
- the gearing can alternatively or additionally provided in the transverse direction of the channel become.
- an L-profile 22 (frame) is fastened, in such a way that the two L-profiles with their vertical Struts facing away from each other. This way, a Frame formed to accommodate a grate.
- the tops the vertical legs of the L-profiles 22 close exactly with a sealed surface, e.g. an asphalt layer 24, which sealed surface is covered by the drainage channel is draining.
- the mouth area the bushing 30 opens to the underside of the gutter top 14 in the horizontal leg 15 towards a circular widened flange area 32, which with the corresponding trained area 32 of the identical channel lower part 16 corresponds. So that the flange area 32 of a gutter upper part 14 always above the flange area 32 of the lower channel part 16 lies, it is necessary to carry out the bushings in axial direction with respect to the center of the channel mirror-symmetrical to arrange. 2 is the implementation 30.32 in axial direction (longitudinal direction) arranged centrally in each channel 12. This ensures that the identical Shaped stone for both the gutter top and the gutter bottom can be used.
- Channel upper part 14 and channel lower part 16 lie on a permeable layer of earth 34 on that below the infiltration channel in the infiltration area 36 loosened again and with a rodent and backwash-proof fabric can be offset, which in the Partition line between cavity 20 and infiltration area 36 is arranged is.
- a fabric can be a geotextile, that the infiltration area 36 lying under the cavity 20 against the ingress of fine substances and thus against fast Clogging protects.
- the geotextile can also have a regulatory function for the settlement of biomass in the infiltration area to have.
- the geotextile itself can be wider than the separation area be between the cavity and the infiltration area, so that the Channel lies on the textile.
- the geotextile Since the geotextile is part of a Maintenance should be cleaned from time to time, it can be on the top or on both sides with a sieve or lattice-like Carrier be provided. In this way, the cavity and thus the geotextile can be cleaned by pressure flushing, without being destroyed.
- the cavity 20 through the interface e.g. the geotextile is effective against one Pollution protected from the infiltration area 36.
- the concrete beds 38 are up to the upper end of the broadened area 26 of the gutter top 14 pulled, so that on the one hand the relative position of the gutter upper part 14 and lower channel part 16 is fixed and the other the gutter up against the thickened section 26 in Contact area 15 of the two U-profiles 14,16 is supported. This construction prevents the earth from settling in Prevents the area of the drainage channel.
- the so fortified Channel 12 is surrounded by a layer of gravel or sand 39.
- the two-part infiltration channel 12 of FIG. 1 is connected to a sink box 40 at the end his.
- the other end is with a vertical cover plate 42 completed so that the area in the area this cover plate 42 no dirt penetrate into the channel 12 can.
- the upper channel part 14 and the lower channel part 16 are with their inlet area 18 and cavity 20 to the sink box open as shown for the gutter top 14 in Fig. 4 which shows a view IV from FIG. 2.
- the implementations 30, 32 between gutter upper part 14 and lower gutter part 16 are shown in dashed lines.
- a detail in the front End of the infiltration channel 12 in the transition area to the gully 40 is shown in section.
- incoming water passes through a connection opening 44 of the Channel upper part 14 in the sink box 40.
- This opening 44 down, i.e. to the bottom area of the watercourse 28 a partition 46 delimits itself from the bottom of the watercourse 28 (FIG. 1) into a certain height of the inlet area 18 extends.
- This partition 46 is used to accumulate in the watercourse 28 To prevent debris from entering the gully 40.
- the gutter lower part 16 is located below Opening 48 connected to the sink box 40.
- the bottom the opening 48 is somewhat from the bottom 50 of the sink box spaced so that the sink box 40 serves as a settling tank, in which coarse dirt accumulates. Arrived from the sink box 40 therefore only relatively clean water in through the opening 48 the cavity 20 of the lower channel part 16, so that this Cavity 20 does not clog too quickly with coarse dirt and sand.
- Sink box 40 can also be used to discharge sewage from other zones to be drained into the infiltration area 20 of the infiltration channel 12 (e.g. roof drainage). Sink box 40 can continue to be connected to a duct 52 which can be used if the Infiltration capacity of the infiltration channel is not sufficient, to remove all the water that is supplied.
- a duct 52 which can be used if the Infiltration capacity of the infiltration channel is not sufficient, to remove all the water that is supplied.
- FIG. 3 shows a further embodiment of an infiltration channel system with a two-part drainage channel and one cistern 51 arranged at the end face.
- Identical or functionally identical Parts to the previous figures are identical Provide reference numerals.
- the infiltration channel system shown in Fig. 3 54 is identical to that in FIG. 1, 2 and 4 shown drainage channel system with the exception, that no bushings 30, 32 between the upper channel part 14 and lower channel part 16 are present. That in the gutter top 14 inflowing water therefore passes through a an opening 44 arranged in the cistern 51. Der Bottom 50 of the cistern 51 is at a considerable distance d from the mouth 48 of the lower channel part 16 is arranged.
- incoming water is in the cistern 50 cleaned and kicked like a settling tank only as an overflow through the front opening 48 into the cavity 20 of the gutter bottom from where it is according to the arrows seeped into the ground.
- the cavity 20 is at its End 51 facing away from the cistern with a vent opening 55 provided so that water from the cistern 51 in the Cavity 20 of the lower channel part can flow.
- Such Vent can also be in the embodiment of the Fig. 2 can be provided, provided that no bushings between Gutter top and gutter bottom are provided or the Ventilation is not sufficient.
- FIG. 5 shows a further embodiment of an infiltration channel, where the gutter top and the gutter bottom in an H-shaped profile are integrated. Identical or functionally identical Parts to the previous figures are identical Provide reference numerals.
- the infiltration channel 58 exists essentially of an H-profile 60, the top two Struts 62 have a smaller distance than the down pointing vertical struts 64 below the horizontal Strut 66, which separates the inlet area 18 from the cavity 20. Due to the fact that the lower two struts 64 each compared to the upper vertical struts 62 by the distance e are offset outwards, the width of the cavity 20 is very much larger than in the embodiments shown so far.
- the watercourse 28 is also in the infiltration channel 58 again asymmetrical, i.e.
- This embodiment has a very good one Infiltration capacity is very high due to the large footprint stable with little additional attachment effort to assemble.
- the solution is particularly useful if one Infiltration channel with a low installation height is required e.g. due to the limited vertical space between Soil and the area to be sealed.
- All of the embodiments of the invention described above have the advantage that the entire inlet area 18 and thus the watercourse after removing the grate over the full Width is accessible from above and therefore easily cleaned can be.
- a sink box or a Cistern is also the cavity 20 over the front Opening 48 to the sink box 40 easily accessible, so that too this area can be serviced.
- the opening 48 can be in operation be closed by a stopper.
- All embodiments have the without wide expansive fastenings Property on that settlement of the soil largely avoided become.
- the widening of the gutter lower part according to FIG. 5 can also be realized with a two-part channel according to FIGS. 1 to 4 become. In this case, the profiles are for gutter top and the lower part of the gutter are of course not identical.
- a grid can be provided which acts as a barrier against coarse dirt and animals.
- All gutter parts can be made of concrete, plastic, metal or other common building materials and composite materials become.
- For gutter top and gutter bottom can also used different materials in the manufacture become.
- a gutter in which the gutter top, e.g. Gutter top 14 from Fig. 1 is omitted.
- Such Channel thus consists only of the lower channel part 16, the horizontal one Then leg 15 is no longer partially permeable, but is closed. The channel is then preferred connected at the front to the surface drainage system.
- Such a gutter can also be used together with inlet drainage gutters used according to the examples above, to increase the total infiltration capacity of the system.
