Definitions
- the present invention relates to an infiltration channel system which is designed in particular for the drainage of partially sealed and sealed surfaces.
- drain channels have been arranged in the sealed area for this purpose, which are connected to a drainage pipe system.
- the main disadvantage of this system is that the drainage pipes become clogged over time and maintenance of these pipes is extremely difficult, and that the soil around the drainage pipes settles.
- the aim of the present invention is to avoid these drawbacks and to provide an infiltration channel system that is easy to maintain and reduces the risk of soil subsidence.
- the infiltration area is arranged under the cavity, which has a bed, possibly with a certain grain size distribution, which hinders clogging by fine substances and, if necessary supports the accumulation of bioflor. Due to the atmospheric cavity of the channel part, the accumulation of aerobic bacteria is possible in the infiltration area, so that a kind of biological cleaning, as it takes place in the natural top soil (humus), is laid underground. In this way, fine particles and even pollutants can be bound by the Bioflor, which counteracts clogging of the infiltration area and surrounding soil area and can even lead to a biological partial clarification of the infiltration water.
- the infiltration area can be separated from the cavity by a geotextile, which prevents fine substances from entering the infiltration area and can also promote the installation of bioflor.
- a geotextile For pressure / suction rinsing of the geotextile as part of maintenance, it is advantageous if the geotextile is provided on one or both sides with a sieve or lattice-like reinforcement in order to avoid damage to the geotextile during the rinsing process.
- the cavity should also be accessible from at least one end face.
- the water is fed to the gutter part, which is open towards the bottom, either via an upper gutter part or via a cistern, sink box or other surface drainage system (e.g. gutter).
- the geotextile can possibly be held interchangeably in the channel, for example on longitudinal guides, so that it can be replaced by fine substances after clogging. It is possible to infiltrate the water not only in the infiltration area, but also in the base layer next to the gutter if this layer is suitable for this (eg gravel fill).
- the inlet area is essentially identical to the infiltration area.
- a drainage channel of this system has one Gutter upper part, into which the water from the sealed or partially sealed surface enters and a downward-facing gully lower part with a cavity into which surface water, e.g. from the gutter upper part via bushings arranged in between or on the front side via a sink box or a cistern or other water storage or processing device is initiated.
- the water flowing into the cavity of the gutter lower part which is open towards the bottom, then seeps into the infiltration area in the floor under the gutter lower part.
- the infiltration area can be protected by a rodent and backwash-proof fabric.
- the mouth of the bushing in the upper channel part is spaced from the bottom of the watercourse in the upper channel part, ie the mouth of the bushing lies in a higher area of the watercourse and thus acts as an overflow for the watercourse. This ensures that the dirt entering the upper part of the gutter collects at the bottom of the watercourse and only the cleaner water flows through the bushings into the lower part of the gutter. Clogging of the bushings between the upper part of the channel and the lower part of the channel is therefore largely excluded.
- the mouth of the lower channel part in the sink box is spaced from the bottom of the sink box, so that the sink box acts as a settling tank. Coarse dirt and sand settle in the sink box or cistern, which means that relatively clean water gets into the lower part of the gutter.
- the invention offers the advantage over the known systems with drainage pipes that the drainage system is laid in one operation together with the drainage line. This way it can even be retrofitted in the area partially sealed surfaces.
- the installation can take place independently of the sewage system.
- the laying does not have to be in the form of continuous continuous drainage lines.
- the channels can be arranged individually, which leaves a lot of leeway in the design of a partially sealed surface.
- the laying can also be done without a slope.
- the infiltration channel preferably consists of two U-profiles facing away from one another, ie with their horizontal legs lying against one another, the U-profile which is open at the top forming the upper channel part and the U-profile which is open below and forms the lower channel part.
- the gutter upper and lower gutters are somewhat widened, so that on the one hand a larger contact surface and on the other on both sides of the gutter there is a widening in the transition area, which serves for the lower gutter for load distribution and for the upper gutter as a float protection.
- Identical U-profiles are preferably used for the gutter upper part and the gutter lower part, so that smaller ones Tool costs for the production of the entire gutter construction are necessary.
- the water course in the gutter top is preferably asymmetrical, i.e. offset to a lateral vertical channel wall, while the mouth is offset for the passage towards the other channel wall.
- This enables the mouth of the bushing to be arranged in a region of the watercourse that rises upwards. The mouth is thus spaced from the bottom of the watercourse, so that dirt falling into the upper channel part collects on the bottom of the watercourse, while the mouth of the passage serves as an overflow for the watercourse.
- the bushings are drilled in a circle in the adjacent part of the two identical U-profiles, so that any axial or lateral misalignment of the gutter does not have the effect that the water on the edges created at the transition e.g. accumulated by getting dirt.
- the enlarged, preferably circular-cylindrical transition in the bushing ensures that even with a slight offset of the gutter upper part to the gutter lower part, trouble-free water flow between the upper gutter part and the lower part of the gutter is ensured.
- the profiles for the upper channel section and the lower channel section are - regardless of whether they are identical - preferably made of molded concrete block.
- a two-part infiltration channel has the advantage that the transport and installation of the channel on site are made considerably easier.
- a one-piece gutter which has an upper section open at the top and a section below and open at the bottom.
- Such an infiltration channel is designed in the manner of an "H". A higher infiltration capacity is obtained if the width of the lower part of the channel exceeds the width of the upper part of the channel. In this way, the cavity and the infiltration area below the channel is larger than the inlet area of the infiltration channel defined by the upper channel part. This increases the drainage capacity of the channel.
- the water supply from the gutter upper part into the gutter lower part can be realized by vertical passages which penetrate the horizontal separation area between the gutter upper part and the gutter lower part.
- a sink pit or cistern can be provided at an end face of an infiltration channel, which absorbs the water entering the channel upper part and passes it on to the channel lower part.
- the region of the mouth of the lower channel part into the sink box should be spaced from the bottom of the sink box.
- the sink box or cistern acts as a sedimentation basin, in which coarse dirt collects.
- An oil separator can be provided in the area of the sink box and / or the cistern, which also allows the infiltration of slightly contaminated surface water.
- a cistern or a sink box storage or water treatment systems can also be provided, into which the water flowing into the upper part of the channel is led.
- the activity of the gutter upper part can thus be decoupled in time from the activity of the gutter lower part. It is still possible to use the upper part of the gutter and bottom part of the channel to be used separately, which greatly expands the possible applications.
- the mouth of the lower part of the gutter in the sink box then acts as an overflow for the sink box, into which mouth only relatively clean water thus enters. In this way, contamination or clogging of the lower part of the channel can be largely ruled out.
- a vertical end wall is inserted in the mouth of the gutter upper part in the sink box, which extends from the bottom of the watercourse up to a certain height, so that the dirt accumulating at the bottom of the watercourse is not passed on to the sink box. This means that coarse parts are filtered out twice before entering the lower part of the channel.
- a sink box or a cistern has the further advantage that the lower part of the channel or the cavity formed in the lower part of the channel is accessible from one end face and can therefore be easily maintained.
- the sink box or the cistern can of course also be used to drain other areas, e.g. for roof drainage.
- the cistern or the sink box can also be provided with an overflow that leads into the sewage system.
- Overflow arranged above the lower part of the gutter can prevent the water level in the lower part of the gutter from rising too high, which could impair the functionality of the entire infiltration system.
- FIG. 1 shows an infiltration channel system 10 with a two-part infiltration channel 12, consisting of an upper channel part 14 and a lower channel part 16.
- the upper channel part 14 and the lower channel part 16 are formed as an identical profile from a concrete block.
- Both U-profiles 14, 16 lie against each other with their horizontal legs 15, which horizontal legs 15 form the separation between the inlet area 18 and the cavity 20 of the infiltration channel 12 which is open towards the bottom.
- the adjacent floor 17 has a rectangular toothing in the longitudinal direction of the groove, with a floating of the Dislocation mortar layer in the resulting cavities is prevented and interlocking between the upper channel part and the lower channel part is achieved.
- a triangle or sine toothing can also be used.
- the toothing can alternatively or additionally be provided in the transverse direction of the channel.
- an L-profile 22 (frame) is attached in such a way that the two L-profiles with their vertical struts face away from each other. In this way, a frame for receiving a grate is formed.
- the tops of the vertical legs of the L-profiles 22 close exactly with a sealed surface, e.g. an asphalt layer 24, which sealed surface is to be drained by means of the infiltration channel.
- the identical U-profile of the lower channel part 16 and the upper channel part 14 are widened 26 in the region of their horizontal adjacent leg 15, so that there is an enlarged contact surface between the two profiles 14, 16.
- a watercourse 28 is formed in the gutter upper part 14, which is displaced somewhat to one side in cross-section with respect to the central axis, ie to the right. To the left, the bottom area of the watercourse rises upwards 29. In this rising area 29, the opening for a passage 30 is arranged, which connects the inlet area 18 with the cavity 20.
- the mouth area of the bushing 30 opens towards the underside of the upper channel part 14 in the horizontal leg 15 in a circular shape widened flange area 32, which corresponds to the correspondingly designed area 32 of the identical channel lower part 16. So that the flange area 32 of an upper channel part 14 always lies above the flange area 32 of the lower channel part 16, it is necessary to arrange the bushings in the axial direction with mirror symmetry with respect to the center of the channel. According to FIG. 2, the bushing 30, 32 is arranged centrally in each channel 12 in the axial direction (longitudinal direction). In this way it is ensured that the identical shaped block can be used both for the upper channel part and for the lower channel part.
- Channel upper part 14 and channel lower part 16 lie on a permeable soil layer 34, which can be loosened again below the infiltration channel in the infiltration area 36 and can be mixed with a rodent and backwash-proof fabric which is arranged in the dividing line between the cavity 20 and the infiltration area 36.
- a fabric can be a geotextile, which protects the infiltration area 36 located under the cavity 20 against the ingress of fines and thus against rapid clogging.
- the geotextile can also have a regulatory function for the settlement of biomass in the infiltration area.
- the geotextile itself can be wider than the separation area between the cavity and the infiltration area, so that the channel lies on the textile.
- the geotextile should be cleaned from time to time as part of a maintenance, it can be provided on the top or on both sides with a sieve or grid-like carrier. In this way, the cavity and thus the geotextile can be cleaned by pressure flushing without being destroyed. In addition, the cavity 20 is effectively protected against contamination from the infiltration area 36 by the separating layer, for example the geotextile.
- the infiltration channel 12 On the soil layer 34, the infiltration channel 12 is fixed by concrete beds 38, which concrete beds widen pyramedally downwards.
- the concrete beds 38 are drawn up to the upper end of the widened area 26 of the upper channel part 14, so that on the one hand the relative position of the upper channel part 14 and the lower channel part 16 is fixed and on the other hand the channel upwards against the thickened section 26 in the contact area 15 of the two U-profiles 14, 16 is supported. This construction prevents the earth from settling in the area of the drainage channel.
- the groove 12 fastened in this way is surrounded by a layer of gravel or sand 39.
- the two-part infiltration channel 12 from FIG. 1 can be connected on the end face to a sink box 40.
- the other end is closed with a vertical cover plate 42, so that no dirt can penetrate into the channel 12 from the surroundings in the area of this cover plate 42.
- the gutter upper part 14 and the gutter lower part 16 are opened with their inlet area 18 and cavity 20 towards the sink box, as is shown for the gutter upper part 14 in FIG. 4, which shows a view IV from FIG. 2.
- the bushings 30, 32 between the upper channel part 14 and the lower channel part 16 are shown in dashed lines.
- a detail in the front end of the infiltration channel 12 in the transition area to the sink box 40 is shown in section.
- the water entering the inlet area 18 (FIG. 1) of the infiltration channel 12 passes through a connecting opening 44 of the channel upper part 14 into the sink box 40.
- This opening 44 is delimited at the bottom, ie towards the bottom area of the water course 28 by a partition 46, which is delimited from the bottom of the watercourse 28 (FIG. 1) extends into a certain height of the inlet area 18.
- This partition 46 is used to prevent debris accumulated in the watercourse 28 from penetrating into the gully 40.
- the gutter lower part 16 is connected to the sink box 40 via an opening 48 located further below.
- the underside of the opening 48 is slightly spaced from the bottom 50 of the sink box, so that the sink box 40 serves as a settling basin in which coarse dirt collects. From the sink box 40, therefore, only relatively clean water enters the cavity 20 of the lower channel part 16 through the opening 48, so that this cavity 20 does not clog too quickly with coarse dirt and sand.
- the sink box 40 can also be used to guide waste water from other zones to be drained into the infiltration area 20 of the infiltration channel 12 (e.g. roof drainage).
- the sink box 40 can also have a channel connection 52 which can be used if the infiltration capacity of the infiltration channel is not sufficient to remove all the water supplied.
- FIG. 3 shows a further embodiment of an infiltration channel system with a two-part infiltration channel and a cistern 51 arranged at the end.
- the infiltration channel system 54 shown in FIG. 3 is identical to the infiltration channel system shown in FIGS. 1, 2 and 4, with the exception that there are no bushings 30, 32 between the upper channel part 14 and the lower channel part 16.
- the water flowing into the gutter upper part 14 therefore reaches the cistern 51 via an opening 44 arranged in an end face Bottom 50 of the cistern 51 is arranged at a considerable distance d from the mouth 48 of the lower channel part 16.
- Water entering the gutter upper part 14 is therefore cleaned in the cistern 50 in the manner of a sedimentation basin and only enters the cavity 20 of the gutter lower part as an overflow via the front opening 48, from where it seeps into the ground according to the arrows.
- the cavity 20 is provided at its end facing away from the cistern 51 with a ventilation opening 55 so that water can flow freely from the cistern 51 into the cavity 20 of the lower part of the channel.
- a vent opening can also be provided in the embodiment of FIG. 2, provided that no passages are provided between the upper part of the channel and the lower part of the channel or the ventilation is not sufficient as a result.
- the infiltration channel 58 essentially consists of an H-profile 60, the upper two struts 62 of which are at a smaller distance than the downward-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 are each offset by the distance e from the upper vertical struts 62 by a distance e, the width of the cavity 20 is very much larger than in the previously illustrated embodiments.
- the watercourse 28 is again arranged asymmetrically, ie offset to the right, while the passage 30 from the inlet area 18 into the cavity 20 is arranged in the left rising area 29 of the watercourse 28.
- This embodiment has a very good infiltration performance and, due to the large footprint, can be installed very steadily with little additional attachment effort.
- the solution is particularly useful when an infiltration channel with a low installation height is required, for example due to the limited vertical space between the soil and the surface 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 is accessible over the full width from above after removal of the grating and can therefore be easily cleaned. If a sink box or a cistern is used, the cavity 20 is also easily accessible via the front opening 48 to the sink box 40, so that this area can also be serviced. The opening 48 can be closed by a plug during operation. All embodiments have the property, even without widely protruding fastenings, that subsidence of the soil is largely avoided. 5 can also be realized with a two-part channel according to FIGS. 1 to 4. In this case, the profiles for the upper channel section and the lower channel section are of course not identical.
- a grating can be provided in the passages 30, 32 between the upper channel part and the lower channel part, which serves 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 will. Different materials can also be used in the manufacture of the gutter top and gutter bottom.
- a gutter in which the gutter top, e.g. Channel upper part 14 from FIG. 1 is omitted.
- a gutter thus only consists of the gutter lower part 16, the horizontal leg 15 of which is then no longer partially permeable, but closed.
- the channel is then preferably connected to the surface drainage system at the end.
- Such a gutter can also be used with inlet drainage gutters according to the previous examples to increase the overall drainage performance of the system.
