Definitions
- the invention relates to a drainage system for a roadway laterally delimited by a curb according to the preamble of patent claim 1.
- a so-called drainage asphalt is known as a road surface that fulfills two functions. On the one hand, traffic noise is reduced and, on the other hand, it enables direct drainage of the road surface, which increases traffic safety (aquaplaning).
- the drainage of the road surface when using drainage asphalt depends on the proportion of pores, which in turn depends on the grain composition of the additives. It is usually between 15 and 25%.
- a direct infiltration through the drainage asphalt is not possible because of the almost waterproof asphalt binder layer below the drainage asphalt in the ground. Since a contamination of the water to be discharged cannot be ruled out, this possibility is also not sought. Above all, there is a risk that the water will impair the load-bearing function of the base layer.
- the invention has for its object to provide drainage for a roadway provided with a water-permeable drainage layer, which can be easily installed and effectively removes both the surface water entering the drainage layer and when the drainage capacity is exhausted.
- the water-permeable strip known per se along the curb is formed by an edge section of the drainage layer, which is supported by a foundation.
- the channel elements forming the channel are shaped so that on the one hand they have lateral (horizontal) openings which are aligned with the edge section. On the other hand, they have upper (vertical) openings at approximately the height of the edge section, as a result of which surface water which has not penetrated the drainage layer is also drained off from the drainage channel in the event of heavy rain.
- the lower edge of the horizontal openings is preferably at the level of the underside of the edge section so that all water that has penetrated into the edge section can be drained off.
- One embodiment of the invention provides that a slotted channel is used, as has become known per se in connection with surface drainage.
- the channel elements of a slot channel are provided with side openings that correspond to the edge section are aligned.
- cross-sectionally U-shaped channel elements can be provided with a water-permeable cover, in particular a grate, the upper side of which lies approximately at the level of the upper side of the edge section.
- the lateral openings aligned with the edge section can be arranged directly below the cover, so that under certain circumstances thickening of the edge section can be dispensed with or the thickening only has to be provided as little as possible.
- the drainage layer is compacted after application (drainage asphalt). If the edge section has the same thickness as the drainage layer, it is inevitably compressed in an analogous manner.
- the cover in particular the grate, can be embedded in the material of the U-shaped channel element, which poses no problems in the production of the channel element from polymer concrete.
- the cover is formed from polymer concrete and has a greater thickness.
- the cover made of polymer concrete has several continuous slots and at least on one side side openings that are connected to the inlet slots.
- the top of the cover must be arranged so that the seal is not damaged when the drainage layer and edge section are compacted and the slope to the cover is retained.
- FIG. 1 to 3 is an identical layer structure to recognize a lane.
- a cover layer 10 made of water-permeable asphalt (drainage asphalt) is supported on a bituminous base layer 14 via a binder layer 12. Underneath there is a further base layer 16.
- a curb 18 extends beside the roadway and is embedded in a foundation 20 made of concrete. Paving stones 22 or slabs form a path on the side of the curb 18 facing away from the roadway.
- An edge section 24a of the drainage layer 10 extends partially over the foundation 20.
- the edge sections are provided with an addition (a, b %), since they are designed differently.
- the edge section 24a extends to the depth of the first base layer 14. It is therefore thicker than the drainage layer 10.
- the edge section 24a borders on a drainage channel which is constructed from individual channel elements 26.
- the trough elements 26a are approximately circular in cross section, but have a slot 28 interrupted by webs on the upper side.
- the top of the channel elements 26 is located slightly below the top of the edge section 24a, so that the inflow of surface water is ensured and the channel is not destroyed during compression.
- the channel elements 26 have also in the longitudinal direction laterally a plurality of holes 30, which are aligned with the edge section 24a, specifically to its lower region, ie the holes 30 are located just above or at the level of the top of the foundation 20 in this region.
- the channel elements 26 are embedded in the foundation 10.
- a grout 32 seals the channel elements 26 from the curb 18.
- the drainage channel is connected to a drain, not shown, which is preferably a sink box, through which the channel sections are accessible.
- U-shaped channel elements 36 are embedded in the foundation 20. They have a grate 38 on the top as a cover, which is supported on a frame 42 which is in the thickened material of the channel element 36 is embedded.
- the frame 42 enables lateral openings 40 to be formed which are aligned with the edge section 24b, the underside of the openings 40 being approximately aligned with the upper side of the foundation 20 in this region.
- the lateral openings 40 enable water to be introduced into the channel via the edge section 24b and thus water that has penetrated into the drainage layer 10. Surface water is discharged into the channel via the grate 38.
- a channel element 44 similar to the channel element 36 is embedded in the foundation 20. However, it is lower than the edge portion 24c.
- a cover 46 Placed on the channel element 44 and optionally connected to it by adhesive or the like, there is a cover 46, which is also made of polymer concrete, like the other channel elements shown in the embodiments.
- the cover 46 has a thickness of a quarter to a third of the height of the channel elements 44 and has two parallel rows of water inlet slots 48.
- the cover 46 has openings 50 which are laterally aligned with the edge section 24c and through which water which has entered the edge section 24 is drained off can be.
- the channel elements 36 according to FIG. 2 have square openings 40 on one side in the upper thickened region, as a result of which water inlet openings are formed.
- the openings 50 are triangular with the tip pointing upward (FIG. 5).
- the openings 50 are provided with an incline 52 which slopes outwards. This prevents material from the edge section (e.g. 24c) from settling into the opening and clogging it during compression.

Description
Die Erfindung bezieht sich auf eine Entwässerung für eine seitlich von einem Bordstein begrenzte Fahrbahn nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a drainage system for a roadway laterally delimited by a curb according to the preamble of patent claim 1.
Als Straßenbelag ist ein sogenannter Dränasphalt bekannt, der zwei Funktionen erfüllt. Zum einen werden die Lärmbelästigungen durch den Verkehr reduziert und zum anderen ermöglicht er eine direkte Entwässerung der Fahrbahnoberfläche, wodurch die Verkehrssicherheit (Aquaplaning) erhöht wird. Die Entwässerung der Fahrbahnoberfläche bei Verwendung von Dränasphalt ist abhängig vom Porenanteil, der wiederum abhängig ist von der Kornzusammensetzung der Zuschlagstoffe. Er beträgt in der Regel zwischen 15 und 25 %.A so-called drainage asphalt is known as a road surface that fulfills two functions. On the one hand, traffic noise is reduced and, on the other hand, it enables direct drainage of the road surface, which increases traffic safety (aquaplaning). The drainage of the road surface when using drainage asphalt depends on the proportion of pores, which in turn depends on the grain composition of the additives. It is usually between 15 and 25%.
Ein direktes Versickern durch den Dränasphalt hindurch ist wegen der annähernd wasserdichten Asphaltbinderschicht unterhalb des Dränasphalts in den Baugrund nicht möglich. Da eine Schadstoffbelastung des abzuführenden Wassers nicht ausgeschlossen werden kann, wird diese Möglichkeit auch nicht angestrebt. Vor allen Dingen besteht die Gefahr, daß das Wasser die Tragfunktion der Tragschicht beeinträchtigt.A direct infiltration through the drainage asphalt is not possible because of the almost waterproof asphalt binder layer below the drainage asphalt in the ground. Since a contamination of the water to be discharged cannot be ruled out, this possibility is also not sought. Above all, there is a risk that the water will impair the load-bearing function of the base layer.
Aus der DE-PS 36 32 620 ist bekannt geworden, entlang des Bordsteins einen Streifen aus ebenfalls wasserdurchlässigem Material vorzusehen, der sich nach unten über die Dränschicht hinaus bis zu einem wasserundurchlässigen Fundament erstreckt und mit mindestens einer Ausnehmung an der Unterseite des Streifens oder im Fundament einen an die Abläufe angeschlossenen Kanal bildet. Das in dem Dränasphalt eindringende Wasser wird seitlich in den wasserdurchlässigen Streifen geleitet und von dort in den darunterliegenden Kanal, der entweder im wasserdurchlässigen Streifen oder im Fundament geformt und mit einem Einlauf verbunden ist. Die Formung eines derartigen Kanals bei dem Bau der Fahrbahn ist verhältnismäßig aufwendig. Ferner können die Kanäle nicht kontrolliert und gereinigt werden, falls sie verstopfen. Außerdem ist die maximal abführbare Wassermenge unter anderem abhängig von dem Porenanteil bzw. der Wasserdurchlässigkeit des Dränasphalts und des wasserdurchlässigen Streifens.From DE-PS 36 32 620 it has become known to provide a strip of likewise water-permeable material along the curb, which extends downward beyond the drainage layer to a water-impermeable foundation and with at least one recess on the underside of the strip or in the foundation forms a channel connected to the processes. The water penetrating into the drainage asphalt is directed laterally into the water-permeable strip and from there into the channel below, which is either formed in the water-permeable strip or in the foundation and is connected to an inlet. The formation of such a channel in the construction of the roadway is relatively expensive. Can also the channels are not checked and cleaned if they become clogged. In addition, the maximum amount of water that can be removed depends, among other things, on the proportion of pores or the water permeability of the drainage asphalt and the water-permeable strip.
Aus der DE-OS 36 19 785 ist bekannt geworden, mindestens teilweise unter dem wasserdurchlässigen Belag linienförmige Ableitelemente anzuordnen, die an die Straßenabläufe oder an Ablaufschächte angeschlossen sind. Die linienförmigen Ableitelemente können als Rinnen ausgebildet sein. Auch bei dieser Ausführungsform ist die Wasserabführungskapazität des Entwässerungssystems von der Wasserdurchlässigkeit des wasserdurchlässigen Fahrbahnbelags abhängig.From DE-OS 36 19 785 it has become known to arrange linear discharge elements at least partially under the water-permeable covering, which are connected to the street gullies or to manholes. The line-shaped discharge elements can be designed as channels. In this embodiment too, the water drainage capacity of the drainage system depends on the water permeability of the water-permeable pavement.
Der Erfindung liegt die Aufgabe zugrunde, eine Entwässerung für eine mit einer wasserdurchlässigen Dränschicht versehene Fahrbahn zu schaffen, die einfach installiert werden kann und sowohl das in die Dränschicht eintretende als auch bei Erschöpfung der Dränkapazität auftretendes Oberflächenwasser wirksam abführt.The invention has for its object to provide drainage for a roadway provided with a water-permeable drainage layer, which can be easily installed and effectively removes both the surface water entering the drainage layer and when the drainage capacity is exhausted.
Diese Aufgabe wird durch die Merkmale des Kennzeichnungsteils des Patentanspruchs 1 gelöst.This object is achieved by the features of the characterizing part of patent claim 1.
Bei der erfindungsgemäßen Entwässerung wird der an sich bekannte wasserdurchlässige Streifen entlang des Bordsteins von einem Randabschnitt der Dränschicht gebildet, die von einem Fundament getragen wird.In the drainage according to the invention, the water-permeable strip known per se along the curb is formed by an edge section of the drainage layer, which is supported by a foundation.
Die den Kanal bildenden Rinnenelemente sind so geformt, daß sie zum einen seitliche (waagerechte) Öffnungen haben, die mit dem Randabschnitt ausgerichtet sind. Sie weisen zum anderen obere (senkrechte) Öffnungen auf in annähernd der Höhe des Randabschnitts, wodurch nicht in die Dränschicht eingedrungenes Oberflächenwasser bei stärkerem Regen ebenfalls von dem Entwässerungskanal abgeführt wird. Vorzugsweise liegt die Unterkante der waagerechten Öffnungen in Höhe der Unterseite des Randabschnitts, damit alles in den Randabschnitt eingedrungene Wasser abgeführt werden kann.The channel elements forming the channel are shaped so that on the one hand they have lateral (horizontal) openings which are aligned with the edge section. On the other hand, they have upper (vertical) openings at approximately the height of the edge section, as a result of which surface water which has not penetrated the drainage layer is also drained off from the drainage channel in the event of heavy rain. The lower edge of the horizontal openings is preferably at the level of the underside of the edge section so that all water that has penetrated into the edge section can be drained off.
Es sind verschiedene Ausbildungen von Rinnenelementen denkbar für die Verwendung im erfindungsgemäßen Entwässerungssystem. Eine Ausgestaltung der Erfindung sieht vor, daß eine Schlitzrinne verwendet wird, wie sie an sich in Verbindung mit der Oberflächenentwässerung bekannt geworden ist. Die Rinnenelemente einer Schlitzrinne sind mit seitlichen Öffnungen versehen, die mit dem Randabschnitt ausgerichtet sind.Various designs of channel elements are conceivable for use in the drainage system according to the invention. One embodiment of the invention provides that a slotted channel is used, as has become known per se in connection with surface drainage. The channel elements of a slot channel are provided with side openings that correspond to the edge section are aligned.
Nach einer anderen Ausgestaltung der Erfindung können im Querschnitt U-förmige Rinnenelemente vorgesehen sein mit einer wasserdurchlässigen Abdeckung, insbesondere einem Rost, deren Oberseite annähernd in Höhe der Oberseite des Randabschnitts liegt. Die seitlichen zum Randabschnitt ausgerichteten Öffnungen können unmittelbar unterhalb der Abdeckung angeordnet sein, so daß unter Umständen auf eine Verdickung des Randabschnitts verzichtet werden kann bzw. die Verdickung nur so gering wie möglich vorgesehen werden muß. Die Dränschicht wird bekanntlich nach dem Aufbringen verdichtet (Dränasphalt). Wenn der Randabschnitt die gleiche Dicke wie die Dränschicht aufweist, wird er zwangsläufig in analoger Weise verdichtet.According to another embodiment of the invention, cross-sectionally U-shaped channel elements can be provided with a water-permeable cover, in particular a grate, the upper side of which lies approximately at the level of the upper side of the edge section. The lateral openings aligned with the edge section can be arranged directly below the cover, so that under certain circumstances thickening of the edge section can be dispensed with or the thickening only has to be provided as little as possible. As is known, the drainage layer is compacted after application (drainage asphalt). If the edge section has the same thickness as the drainage layer, it is inevitably compressed in an analogous manner.
Die Abdeckung, insbesondere der Rost, kann in das Material des U-förmigen Rinnenelements eingebettet sein, was bei der Fertigung des Rinnenelements aus Polymerbeton keine Probleme bereitet.The cover, in particular the grate, can be embedded in the material of the U-shaped channel element, which poses no problems in the production of the channel element from polymer concrete.
Bei einer bevorzugten Ausgestaltung der Erfindung wird die Abdeckung aus Polymerbeton gebildet und weist eine größere Dicke auf. Die Abdeckung aus Polymerbeton weist mehrere durchgehende Schlitze auf sowie mindestens auf einer Seite seitliche Öffnungen, die mit den Einlaufschlitzen verbunden sind. Die Oberseite der Abdeckung ist so anzuordnen, daß beim Verdichten von Dränschicht und Randabschnitt die Abdichtung nicht beschädigt wird und das Gefälle zur Abdeckung erhalten bleibt.In a preferred embodiment of the invention, the cover is formed from polymer concrete and has a greater thickness. The cover made of polymer concrete has several continuous slots and at least on one side side openings that are connected to the inlet slots. The top of the cover must be arranged so that the seal is not damaged when the drainage layer and edge section are compacted and the slope to the cover is retained.

In den Figuren 1 bis 3 ist ein identischer Schichtaufbau einer Fahrbahn zu erkennen. Eine Deckschicht 10 aus wasserdurchlässigem Asphalt (Dränasphalt) stützt sich über eine Binderschicht 12 auf einer bituminösen Tragschicht 14 ab. Darunter befindet sich eine weitere Tragschicht 16. Neben der Fahrbahn erstreckt sich ein Bordstein 18, der in ein Fundament 20 aus Beton eingelassen ist. Pflastersteine 22 oder Platten bilden einen Weg auf der der Fahrbahn abgewandten Seite des Bordsteins 18.In Figures 1 to 3 is an identical layer structure to recognize a lane. A
Ein Randabschnitt 24a der Dränschicht 10 erstreckt sich teilweise über das Fundament 20. Bezüglich der Figuren 1 bis 3 sind die Randabschnitte mit einem Zusatz (a, b...) versehen, da sie unterschiedlich ausgeführt sind.An edge section 24a of the
In Fig. 1 erstreckt sich der Randabschnitt 24a bis in Tiefe der ersten Tragschicht 14. Er ist daher dicker als die Dränschicht 10. Der Randabschnitt 24a grenzt an eine Entwässerungsrinne an, die aus einzelnen Rinnenelementen 26 aufgebaut ist. Die Rinnenelemente 26a sind annähernd im Querschnitt kreisförmig geschlossen, weisen jedoch an der Oberseite einen von Stegen unterbrochenen Schlitz 28 auf. Die Oberseite der Rinnenelemente 26 liegt etwas unterhalb der Oberseite des Randabschnitts 24a, so daß der Einlauf von Oberflächenwasser gewährleistet ist und die Rinne beim Verdichten nicht zerstört wird. Die Rinnenelemente 26 weisen außerdem in Längsrichtung seitlich mehrere Löcher 30 auf, die zum Randabschnitt 24a ausgerichtet sind, und zwar zu seinem unteren Bereich, d.h. die Löcher 30 liegen kurz oberhalb oder in Höhe der Oberseite des Fundaments 20 in diesem Bereich.In FIG. 1, the edge section 24a extends to the depth of the
Die Rinnenelemente 26 sind im Fundament 10 eingebettet. Ein Fugenverguß 32 dichtet die Rinnenelemente 26 gegenüber dem Bordstein 18 ab.The
Auf der Dränschicht 10 befindliches Wasser dringt in diese ein und wird wegen der Undurchlässigkeit der Binderschicht 12 seitlich in den Randabschnitt 24a abgeführt und kann über die Löcher 30 in die Entwässerungsrinne eintreten. Oberflächenwasser, das bei größerer Regenmenge bzw. Erschöpfung der Dränschicht seitlich abfließt, kann über den Schlitz 28 in die Entwässerungsrinne eintreten. Die Entwässerungsrinne ist mit einem nicht gezeigten Ablauf verbunden, der vorzugsweise ein Sinkkasten ist, über den die Rinnenabschnitte zugänglich sind.Water located on the
Bei der Ausführungsform nach Fig. 2 sind U-förmige Rinnenelemente 36 im Fundament 20 eingebettet. Sie weisen an der Oberseite als Abdeckung einen Rost 38 auf, der sich auf einem Rahmen 42 abstützt, der in das verdickte Material des Rinnenelements 36 eingebettet ist. Der Rahmen 42 ermöglicht die Ausformung von seitlichen Öffnungen 40, die zum Randabschnitt 24b ausgerichtet sind, wobei die Unterseite der Öffnungen 40 annähernd mit der Oberseite des Fundaments 20 in diesem Bereich ausgerichtet ist. Die seitlichen Öffnungen 40 ermöglichen die Einleitung von Wasser in die Rinne über den Randabschnitt 24b und damit von in die Dränschicht 10 eingedrungenem Wasser. Über den Rost 38 wird Oberflächenwasser in die Rinne abgeführt.In the embodiment according to FIG. 2,
Bei der Ausführungsform nach Fig. 3 ist ein Rinnenelement 44 ähnlich dem Rinnenelement 36 im Fundament 20 eingebettet. Es liegt jedoch tiefer als der Randabschnitt 24c. Auf das Rinnenelement 44 aufgesetzt und gegebenenfalls mit diesem durch Klebung oder dergleichen verbunden, ist eine Abdeckung 46, die ebenfalls aus Polymerbeton besteht, wie die übrigen in den Ausführungsformen gezeigten Rinnenelemente. Die Abdeckung 46 hat eine Dicke von einem Viertel bis zu einem Drittel der Höhe der Rinnenelemente 44 und besitzt zwei parallele Reihen von Wassereintrittsschlitzen 48. Außerdem weist die Abdeckung 46 seitlich zum Randabschnitt 24c ausgerichtete Öffnungen 50 auf, über die in den Randabschnitt 24 eingetretenes Wasser abgeführt werden kann.In the embodiment according to FIG. 3, a
In Fig. 5 ist zu erkennen, daß die Rinnenelemente 36 nach Fig. 2 im oberen verdickten Bereich auf einer Seite quadratische Öffnungen 40 aufweisen, wodurch Wassereintrittsöffnungen gebildet sind. Bei den Rinnenelementen 44 bzw. der Abdeckung 46 dafür ist zu erkennen, daß die Öffnungen 50 dreieckig sind mit nach oben weisender Spitze (Fig. 5). Nach unten sind die Öffnungen 50 mit einer nach außen abfallenden Schräge 52 versehen. Dadurch wird verhindert, daß beim Verdichten sich Material des Randabschnitts (z.B. 24c) in die Öffnung setzt und diese verstopft.5 that the
