Abstract

The invention relates to a draining ditch for the draining of roadways comprising a ditch body of U-shaped cross-sectional area which is potted in the concrete bed of the roadway and a cover plate or body covering the upper surface of the ditch body, the plate being provided with an abrasion resistance equal to or less than that of the roadway and having a thickness of at least half of the width of the ditch body and with a plurality of inlet openings.

Description

Die Erfindung bezieht sich auf eine Entwässerungsrinne für die Querentwässerung von Fahrbahnen mit einem im Querschnitt U-förmigen, im Material der Fahrbahn formschlüssig einbettbaren Rinnenkörper und einer die Oberseite des Rinnenkörpers abdeckenden Abdeckung, die eine Vielzahl von Wassereinlauföffnungen aufweist, wobei Rinnenkörper und Abdeckung aus Kunstharzbeton geformt sind.The invention relates to a drainage channel for the cross-drainage of roadways with a cross-sectionally U-shaped channel body that can be embedded in the material of the roadway and a cover that covers the upper side of the channel body and that has a multiplicity of water inlet openings, the channel body and cover being formed from synthetic resin concrete are.

Eine derartige Entwässerungsrinne ist bekannt (DE-U-7 036 272). Rinnenkörper und Abdeckung sind vorteilhafterweise aus Polymerbeton geformt. Die Abdeckung ist auf Absätzen versenkt innerhalb des Rinnenkörpers angeordnet, so dass ihre Oberfläche annähernd mit der Oberkante der Rinnenkörperwände abschliesst.Such a drainage channel is known (DE-U-7 036 272). The channel body and cover are advantageously formed from polymer concrete. The cover is arranged recessed on shoulders inside the channel body, so that its surface is approximately flush with the upper edge of the channel body walls.

Bei der bekannten Entwässerungsrinne ist auch bekannt, eine Abdeckung von relativ grosser Dicke zu wählen. Sie wird bei einem Rinnenkörper eingesetzt, dessen eine Seitenwand gegenüber der anderen niedriger ausgeführt ist. Seitliche Öffnungen in der Abdeckung dienen dazu, auch seitliches Oberflächenwasser in den Rinnenkörper einlaufen zu lassen.In the known drainage channel, it is also known to choose a cover of relatively large thickness. It is used for a channel body, one side wall of which is lower than the other. Lateral openings in the cover also serve to allow lateral surface water to run into the channel body.

Beide beschriebenen Anwendungsfälle sind nicht für die Querentwässerung von stark befahrenen Fahrbahnen geeignet. Die Abdeckungen liegen lose durch Eigengewicht auf den Rinnenkörperwänden auf. Sie können daher durch Sog oder andere Einwirkungen sehr leicht herausgerissen werden. Ein Verschleiss der Abdeckung würde gleichzeitig zu einem Verschleiss der oberen Abschnitte der Rinnenwände führen, wodurch die Gefahr besteht, dass die Abdeckung nicht mehr sicher gehaltert ist.Both of the applications described are not suitable for the cross-drainage of busy roads. The covers are loose due to their own weight on the channel body walls. They can therefore be torn out very easily by suction or other influences. Wear of the cover would at the same time lead to wear of the upper sections of the channel walls, which means that there is a risk that the cover is no longer securely held.

Es ist ferner bekannt, Abdeckungen unlösbar mit den Rinnenkörpern einer Entwässerungsrinne zu verbinden (DE-A-2 703 583). Eine derartige Verbindung kann beispielsweise durch Verkleben erfolgen. Zusätzlich kann eine Verankerung durch Betonanker oder dergleichen durchgeführt werden. Die Abdeckungen sind Guss- oder Stahlroste, die bei Fahrbahnen mit hoher Fahrzeugfrequenz und hohen Geschwindigkeiten (Autobahnen) hohen dynamischen Kräften ausgesetzt und diesen nicht immer gewachsen sind. Zumindest besteht die Gefahr, dass die Abdeckkonstruktion bricht und dadurch massive Fremdkörper auf die Fahrbahn gelangen und Gefahren heraufbeschwören. Auch wenn die Abdeckungen aus Stahl oder Gusseisen ausreichend fest sind, haben sie den Nachteil, dass sie eine Absenkung der Fahrbahn durch Abrieb nicht mitmachen. Die Fahrbahnabsenkung hat zur Folge, dass die Wassereinlaufzone höher liegt als die Fahrbahnenebene, so dass es zu einer Wasseransammlung mit der Gefahr des Aquaplaning kommen kann. Ausserdem bildet die herausragende Metallkonstruktion ein Hindernis in der Fahrbahn. Beim Überfahren mit hoher Geschwindigkeit verursacht sie harte Schläge, welche sich ungünstig auf das Fahrzeug auswirken und für den Fahrer unangenehm sind.It is also known to connect covers inseparably to the channel bodies of a drainage channel (DE-A-2 703 583). Such a connection can be made, for example, by gluing. In addition, anchoring can be carried out by concrete anchors or the like. The covers are cast or steel gratings that are exposed to high dynamic forces on roads with high vehicle frequencies and high speeds (highways) and are not always able to withstand them. At least there is a risk that the cover structure breaks and massive foreign objects get onto the roadway and create dangers. Even if the covers made of steel or cast iron are sufficiently strong, they have the disadvantage that they do not participate in lowering the road surface due to abrasion. The lowering of the carriageway means that the water inlet zone is higher than the carriageway level, so that water can accumulate with the risk of aquaplaning. In addition, the outstanding metal construction forms an obstacle in the road. When driving over at high speed, it causes hard impacts, which have an unfavorable effect on the vehicle and are uncomfortable for the driver.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Entwässerungsrinne für die Querentwässerung von Fahrbahnen zu schaffen, deren Abdeckung starken Belastungen gewachsen ist und deren Wassereinlaufzone auch während längeren Gebrauchs stets in der Ebene der Fahrbahnebene oder etwas darunter liegt.The invention is therefore based on the object to provide a drainage channel for the cross-drainage of roadways, the cover has grown strong loads and the water inlet zone is always in the level of the roadway level or slightly below, even during prolonged use.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Abdeckung einen unteren Auflageabschnitt und einen oberen Soll-Verschleissabschnitt aufweist, dass der Auflageabschnitt im Querschnitt bis zu den oberen Aussenkanten des Rinnenkörpers reicht und von geringerer Dicke als der Soll-Verschleissabschnitt ist, dass letzterer schmaler ist als der Auflageabschnitt und durch eine befahrbare Oberfläche begrenzt wird, die die minimale Querschnittsbreite der gesamten Abdeckung aufweist, dass die Gesamtdicke der Abdeckung mindestens der halben lichten Weite des Rinnenkörpers ist und dass auch die Abdeckung formschlüssig in das Material der Fahrbahn einbaubar ist, wobei das Material der Abdeckung so gewählt ist, dass die Senkung der Oberfläche des Soll-Verschleissabschnitts infolge Abriebs nicht geringer sein soll als jene der angrenzenden Fahrbahnfläche.This object is achieved according to the invention in that the cover has a lower support section and an upper desired wear section, that the support section extends in cross-section to the upper outer edges of the channel body and is of a smaller thickness than the desired wear section in that the latter is narrower than the support section and is delimited by a drivable surface that has the minimum cross-sectional width of the entire cover, that the total thickness of the cover is at least half the inside width of the channel body and that the cover can also be positively installed in the material of the roadway, the material of the Covering is chosen so that the lowering of the surface of the target wear section due to abrasion should not be less than that of the adjacent road surface.

Erfindungsgemäss ist die Abdeckung sehr dick ausgebildet und setzt sich aus einem oberen Verschleissabschnitt und einem unteren Auflageabschnitt zusammen. Der Auflageabschnitt stützt sich auf der Oberseite der Rinnenkörperwände ab, während der Verschleissabschnitt an der Oberseite eine befahrene Oberfläche bildet. Da die Abdeckung aus Polymerbeton besteht, kann durch die Wahl der richtigen Zuschläge und der Zuschlagsanteile ein gewünschter Abriebfaktor eingestellt werden, der in etwa dem der Fahrbahn gleicht, in der die erfindungsgemässe Entwässerungsrinne zum Einsatz kommen soll. Damit ein nennenswerter Abrieb tatsächlich stattfinden kann, muss der Verschleissabschnitt eine gewisse Dicke aufweisen.According to the invention, the cover is made very thick and is composed of an upper wear section and a lower support section. The support section is supported on the top of the channel body walls, while the wear section forms a traffic surface on the top. Since the cover is made of polymer concrete, a desired abrasion factor can be set through the choice of the correct aggregates and the aggregate proportions, which roughly corresponds to that of the road in which the drainage channel according to the invention is to be used. So that a significant abrasion can actually take place, the wear section must have a certain thickness.

Die Breite des Aflageabschnitts ist grösser als die des Verschleissabschnitts. Es ergibt sich daher im Querschnitt eine mehr oder weniger konische Form, wodurch eine sichere Verankerung im Material der Fahrbahn möglich ist. Auch durch grosse an der Abdeckung angreifende Kräfte kann diese nicht vom Rinnenkörper entfernt und fortgeschleudert werden.The width of the support section is greater than that of the wear section. This results in a more or less conical shape in cross-section, which enables secure anchoring in the material of the roadway. Even due to large forces acting on the cover, it cannot be removed from the channel body and flung away.

Es kann vorteilhaft sein, Abdeckung und Rinnenkörper vor dem Einbauen miteinander zu verbinden, beispielsweise durch ein Verkleben. Die Verklebung spielt für den Betrieb der erfindungsgemässen Entwässerungsrinne keine Rolle. Sie dient daher nicht einer zusätzlichen Verankerung der Abdeckung am Rinnenkörper. Aus fertigungstechnischen Gründen ist jedoch das Verkleben am Herstellungsort vorzuziehen. Ausserdem können Rinnenkörper und Abdeckplatte gemeinsam verlegt werden, was eine Montageeinsparung an der Baustelle mit sich bringt. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Unteransprüchen angegeben.It may be advantageous to connect the cover and the channel body to one another before installation, for example by gluing. The bonding plays no role in the operation of the drainage channel according to the invention. It is therefore not used for an additional anchoring of the cover on the channel body. For manufacturing reasons, however, bonding at the manufacturing site is preferable. In addition, the channel body and cover plate can be installed together, which saves assembly costs at the construction site. Further advantageous embodiments of the invention are specified in further subclaims.

In Fig. 2 sind zwei verschiedene Rinnenkörper durch jeweils eine Seitenwand 10 bzw. 11 angedeutet. Sie sind im Querschnitt von ähnlicher Form, weisen jedoch unterschiedliche lichte Weiten auf. Der Rinnenkörper 10 besitzt eine lichte Weite von 200 und der Rinnenkörper 11 eine lichte Weite von 100 mm. Die Rinnenkörper sind aus Polyesterbeton in üblicherweise geformt. An der Oberseite besitzen sie einen im Querschnitt rechteckförmigen erhabenen Kantenbereich 12 bzw. 13, durch den eine langgestreckte Ausnehmung 14 bzw. 15 an der Innenseite der Seitenwände gebildet ist mit einer Schulter 16 bzw. 17.In Fig. 2 two different channel bodies are indicated by a side wall 10 and 11, respectively. They are of similar shape in cross-section, but have different clear widths. The channel body 10 has a clear width of 200 and the channel body 11 has a clear width of 100 mm. The channel bodies are usually made of polyester concrete. On the upper side they have a raised edge region 12 or 13 with a rectangular cross section, through which an elongated recess 14 or 15 is formed on the inside of the side walls with a shoulder 16 or 17.

Die Abdeckung für die beispielhaften Rinnenkörper ist allgemeinen mit 20 bezeichnet. Sie besitzt einen unteren Auflageabschnitt 21 und einen oberen Verschleissabschnitt 22. Der Auflageabschnitt 21 besitzt eine untere Fläche 23, in die zwei parallele Nuten eingeformt sind, von denen eine bei 24 gezeigt ist. In die unteren Kanten des Auflageabschnitts 21 sind in Längsrichtung sich erstreckende im Querschnitt rechteckförmige Ausnehmungen 25 bzw. 26 geformt. Wie man Fig. 2 entnehmen kann, greifen die erhaltenen Abschnitte 12 bzw. 13 in die Nuten 24 bzw. die seitlichen Ausnehmungen 25 bzw. 26 ein, wobei die untere Fläche 23 auf den Schultern 16 bzw. 17 aufsitzt. Die Aussenseiten des Auflageabschnitts 21 schliessen dabei bündig mit der Aussenseite der Wände des Rinnenkörpers 10 ab.The cover for the exemplary gutter body is generally designated 20. It has a lower support section 21 and an upper wear section 22. The support section 21 has a lower surface 23 into which two parallel grooves are formed, one of which is shown at 24. In the lower edges of the support section 21, recesses 25 and 26, which are rectangular in cross section and extend in the longitudinal direction, are formed. As can be seen in FIG. 2, the sections 12 and 13 obtained engage in the grooves 24 and the lateral recesses 25 and 26, respectively, the lower surface 23 being seated on the shoulders 16 and 17, respectively. The outside of the support section 21 is flush with the outside of the walls of the channel body 10.

Aus Fig. 2 ist zu erkennen, dass durch eine geringfügige Modifizierung der Abdeckung 20 Rinnenkörper unterschiedlicher lichter Weite abgedeckt werden können.It can be seen from FIG. 2 that a slight modification of the cover can cover 20 channel bodies of different clear widths.

Der Auflageabschnitt 21 der Abdeckung 20 ist an seiner Oberseite, wie bei 27 gezeigt, dachförmig und geht in den Verschleissabschnitt 22 über, der sich stetig geringförmig nach oben in seiner Breite verringert. Die Höhe des Verschleissabschnitts 22 ist annähernd doppelt so gross wie die des Auflageabschnitts 21, und die Gesamthöhe der Abdeckung 20 ist im Bereich der lichten Weite des Rinnenkörpers 10. An die Aussenseiten von Auflage- und Verschleissabschnitt sind jeweils in Längsrichtung beabstandete Rippen 28 angeformt, die die Seitenstabilität der Abdeckung 20 vergrössern.The support section 21 of the cover 20 is roof-shaped on its upper side, as shown at 27, and merges into the wear section 22, which gradually decreases in width upwards. The height of the wear section 22 is approximately twice as large as that of the support section 21, and the total height of the cover 20 is in the range of the clear width of the channel body 10. On the outside of the support and wear section, ribs 28 are formed which are spaced apart in the longitudinal direction increase the lateral stability of the cover 20.

Die befahrene Oberfläche 29 des Verschleissabschnitts 22 bildet die Wassereinlaufzone. Sie liegt nach dem Einbau des Rinnenkörpers mit der Abdeckung 20 auf gleichem Niveau wie die Fahrbahnebene, wie durch den Pfeil 30 angedeutet. Im übrigen ist der Rinnenkörper zusammen mit der Abdeckung in das Betonbett bzw. das Material der Fahrbahndecke eingebaut, so dass eine sichere Verankerung der Abdeckung gewährleistet ist.The traversed surface 29 of the wear section 22 forms the water inlet zone. After installation of the channel body with the cover 20, it lies at the same level as the roadway level, as indicated by the arrow 30. In addition, the channel body is installed together with the cover in the concrete bed or the material of the pavement, so that the cover is securely anchored.

Dadurch, dass die Abdeckung 20 ebenfalls aus abreibbarem Material besteht, insbesondere Polyesterbeton, wird der Verschleissabschnitt 22 zusammen mit der Fahrbahn abgetragen, so dass sichergestellt ist, dass die Wassereinlaufzone stets auf dem Niveau der Fahrbahnebene 30 oder darunter liegt.Because the cover 20 also consists of a material that can be rubbed off, in particular polyester concrete, the wear section 22 is removed together with the roadway, so that it is ensured that the water inlet zone is always at the level of the roadway level 30 or below.

Wie aus den Figuren 1 und 2 zu erkennen, sind drei Reihen von jeweils hintereinander angeordneten sich in Längsrichtung erstreckenden, schlitzartigen Wassereinlauföffnungen 31 geformt, die sich nach unten in bekannter Weise etwas erweitern. Die Einlauföffnungen 31 einer Reihe sind gegenüber den benachbarten jeweils um eine halbe Länge versetzt, um eine ausreichende Stabilität der Abdeckung beizubehalten.As can be seen from FIGS. 1 and 2, three rows of slot-like water inlet openings 31, which are arranged one behind the other and are formed in the longitudinal direction, are formed, which expand somewhat downward in a known manner. The inlet openings 31 of a row are offset by half a length in relation to the neighboring ones in order to maintain sufficient stability of the cover.

Rinnenkörper und Abdeckung 20 werden nach der Herstellung mittels einer geeigneten Klebemasse fest miteinander verbunden, so dass sie als Einheit an der Baustelle gehandhabt und eingebaut werden.After production, the channel body and cover 20 are firmly connected to one another by means of a suitable adhesive, so that they are handled and installed as a unit at the construction site.

Die Abdeckung 40 nach den Figuren 3 und 4 ist ähnlich der nach den Figuren 1 und 2 aufgebaut. Sie besitzt drei parallele Reihen von Wassereinlauföffnungen 41, die, wie in Fig. 4 durch gestrichelte Linien angedeutet, sich ebenfalls von unten nach oben etwas verjüngen. Die Wassereinlauföffnungen 41 sind gegenüber den Öffnungen zur benachbarten Reihe jeweils auf Lücke angeordnet. Die Anordnung der Wassereinlauföffnungen 41 ist derart, dass in der mittleren Reihe die Einlauföffnungen zur Stirnseite hin geöffnet sind, wie etwa bei 42 gezeigt. Die Oberfläche 43 der Abdeckung 40, die wiederum in Höhe des Fahrbahnniveaus liegt, ist mit drei parallelen Nuten 44 versehen, in die die oberen Enden der Einlauföffnungen 41 münden, wie in den Figuren 3 und 4 deutlich zu erkennen. Die oberen Kanten der Abdeckung 40 sind, wie bei 45 gezeigt, angeschrägt.The cover 40 according to FIGS. 3 and 4 is constructed similarly to that according to FIGS. 1 and 2. It has three parallel rows of water inlet openings 41 which, as indicated by dashed lines in FIG. 4, also taper somewhat from bottom to top. The water inlet openings 41 are each arranged in a gap with respect to the openings to the adjacent row. The arrangement of the water inlet openings 41 is such that in the middle row the inlet openings are open towards the front, as shown at 42. The surface 43 of the cover 40, which in turn lies at the level of the roadway, is provided with three parallel grooves 44 into which the upper ends of the inlet openings 41 open, as can be clearly seen in FIGS. 3 and 4. The top edges of cover 40 are chamfered, as shown at 45.

Im unteren Bereich ist die Abdeckung 40 mit einer durchgehenden Ausnehmung 46 bzw. 47 versehen, um in ähnlicher Weise mit einem nicht gezeigten Rinnenkörper zusammenzuwirken, wie dies in Fig. 2, linke Hälfte, gezeigt ist.In the lower area, the cover 40 is provided with a continuous recess 46 or 47 in order to cooperate in a similar manner with a channel body, not shown, as shown in FIG. 2, left half.

Die gezeigte Abdeckung nach den Figuren 3 und 4 hat in Längsrichtung konstanten Querschnitt, wobei die Aussenseiten 48, 49 konkav gewölbt sind.
