Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Sicherung eines Straßenkanaldurchlasses gegen den Frontalaufprall eines von der höher gelegenen Fahrbahn abgekommenen Fahrzeuges, mit einer trapezförmigen Auffahrplatte, die mit beiden Trapezseiten auf die Straßenkanalböschung auflegbar, mit ihrer größeren Trapezbasis an der Stirnseite des Straßenkanaldurchlasses auf der Höhe der Fahrbahn od.dgl. und mit ihrer kleineren Trapezbasis auf der Straßenkanalsohle abstützbar ist.The present invention relates to a device for Securing a street channel passage against a frontal impact a vehicle that has strayed from the higher lane, with a trapezoidal ramp, which with both Trapezoidal pages can be placed on the road canal embankment with your larger trapezoidal base at the front of the street channel passage or the like at the level of the road. and with her smaller one Trapezoidal base is supported on the street channel sole.

Insbesondere auf Freilandstraßen besteht in der Regel ein relativ großer Niveauunterschied zwischen der Fahrbahn und an den Straßenkanal der Fahrbahn angrenzenden Flächen, wie Feldern u.dgl. Im Bereich von Brücken, die Fahrbahn kreuzenden oder in diese einmündenden weiteren Fahrbahnen usw. verlaufen unter diesen zur Entwässerung dienende Straßenkanaldurchlässe, zumeist in Form von Betonrohren, in Fluchtung mit dem offenen Straßenkanal am Fahrbahnrand. Kommt ein Fahrzeug im Bereich vor dem Straßenkanaldurchlaß von der Fahrbahn ab und gerät auch wegen des Niveauunterschiedes zur angrenzenden Fläche über die seitliche Böschung in den offenen Straßenkanal, so kann es im Bereich des Straßenkanaldurchlasses zu einem Frontalaufprall des Fahrzeuges auf die Stirnseite des Durchlasses, d.h. auf das Kanalrohr kommen, was zu schweren Unfällen führen kann.In particular on open roads, there is usually a relatively large level difference between the road and on the road channel of the roadway adjacent areas, such as fields and the like In the area of bridges, crossing the road or in these further flowing lanes etc. run under these drainage road passages, mostly in the form of concrete pipes, in alignment with the open one Road canal at the edge of the road. If a vehicle occurs in the area the street channel passage from the roadway and also because of the level difference to the adjacent surface over the embankment in the open road channel, so it can be in the Area of the road channel passage to a frontal impact of the vehicle on the face of the culvert, i.e. on the Sewer pipe come, which can lead to serious accidents.

Aus der FR 2 581 101 ist eine Vorrichtung der einleitend angegebenen Art bekannt, deren Auffahrplatte mit beiden Trapezseiten und allfälligen seitlichen Verlängerungen ausschließlich auf der Straßenkanalböschung aufliegt, was zur Folge hat, daß ein von der Fahrbahn abgekommenes Fahrzeug in den Straßenkanal bis zur Böschung desselben abwärts fährt. Dies kann wegen der Böschungsneigung einen schwerwiegenden Aufprall zur Folge haben. Die bekannte Auffahrplatte ist außerdem in ihrer unteren Hälfte mit großdurchmeßrigen Durchtrittsöffnungen versehen, die bei einem Aufprall ebenfalls nachteilige Folgen haben können.FR 2 581 101 is an introductory device specified type known, the ramp with both trapezoidal sides and any side extensions only rests on the road channel embankment, which means that a vehicle that has strayed from the road into the street channel down to the embankment. This can be because of the Slope slope results in a severe impact to have. The well-known ramp is also in its lower Half provided with large-diameter openings that can also have adverse consequences in the event of an impact.

Die Erfindung zielt nun darauf ab, eine Sicherheitsvorrichtung zu schaffen, welche nicht nur den Aufprall eines Fahrzeuges auf die Stirnseite des Straßenkanaldurchlasses verhindert, sondern zugleich ein Überleiten des Fahrzeuges auf eine an den Straßenkanal bzw. dessen Böschung angrenzende Fläche, z.B. ein Feld, ermöglicht. Die erfindungsgemäße Sicherheitsvorrichtung zeichnet sich dadurch aus, daß sie aus Stahlbeton hergestellt ist und sowohl auf der der Fahrbahn gegenüberliegenden Straßenkanalböschung als auch einer an den Straßenkanal angrenzenden, tiefer als das Fahrbahnniveau liegenden Fläche abstützbar ist oder die Auffahrplatte nur auf der der Fahrbahn abgewandten Trapezseite mit einer dreieckförmigen Verlängerung versehen ist, die mit der Auffahrplatte vorzugsweise lösbar verbunden ist und einerseits auf der Stirnseite des Straßenkanaldurchlasses in Fluchtung mit der größeren Trapezbasis sowie anderseits am Übergang zwischen Straßenkanal und angrenzender Fläche abstützbar ist, wobei die Auffahrplatte nur im Bereich der kleineren Trapezbasis mit einer von einem Gitter abgedeckten Wasserdurchlaßöffnung versehen ist und in der Auffahrplatte sowie vorzugsweise auch in deren Verlängerung an sich bekannte Aufnahmeorgane eingegossen sind.The invention now aims at one Safety device to create which is not just the impact of a vehicle prevented on the front side of the street channel passage, but at the same time transferring the vehicle to one area adjacent to the road canal or its embankment, e.g. a field that enables. The safety device according to the invention is characterized by the fact that it is made of reinforced concrete and both on the opposite side of the road Road canal embankment as well as one adjacent to the road canal can be supported lower than the level of the road surface or the ramp is only on the side facing away from the road Trapezoidal side with a triangular extension is, which is preferably releasably connected to the ramp is and on the one hand on the front side of the street channel passage in alignment with the larger trapezoidal base as well on the other hand, at the transition between the street channel and the adjacent one Surface is supported, the ramp plate only in the area the smaller trapezoidal base with one covered by a grid Water passage opening is provided and in the ramp and preferably also known in their extension Receiving organs are cast.

Durch diese Konstruktion wird einerseits eine den Straßenkanal vor dem Stirnbereich des Straßenkanaldurchlasses abdekkende, schräg verlaufende Auffahrfläche für ein von der Fahrbahn abgekommenes Fahrzeug geschaffen, auf welche das Fahrzeug mit den Rädern aufkommt und auf der es abgebremst wird, und anderseits erreicht, daß die Auffahrfläche auch mit der an den Straßenkanal angrenzenden, im wesentlichen parallel zur Fahrbahn verlaufenden Fläche, z.B. einem Feld, über eine Kante in Verbindung steht, so daß das abgekommene Fahrzeug über die Auffahrplatte auf die an den Straßenkanal angrenzende Fläche abgelenkt wird. Die nur im Sohlenbereich des Straßenkanals in der Auffahrplatte vorhandene Wasserdurchlaßöffnung sichert, daß die Wirkung des Straßenkanals auch bei starken Regenfällen voll aufrecht erhalten bleibt.With this construction, on the one hand, the street canal covering in front of the front area of the street channel passage sloping ramp for one from the road stray vehicle created on which the vehicle comes up with the wheels and on which it is braked, and on the other hand achieved that the drive-on surface also with the at the Road channel adjacent, essentially parallel to the road running surface, e.g. a field, over an edge in Connection is established, so that the stray vehicle on the ramp distracted to the area adjacent to the street canal becomes. The only in the sole area of the street channel in the Access plate existing water passage ensures that the Effect of the street canal even in heavy rain is maintained.

Im Falle des Vorsehens einer Verlängerung, die vorzugsweise mit der Auffahrplatte lösbar verbindbar ist, geht diese über einen stumpfen Winkel in die eigentliche Auffahrplatte über und sichert eine kontinuierliche Auffahrfläche in dem Bereich zwischen der Querfahrbahn od.dgl. und der an den Straßenkanal angrenzenden Fläche.In the case of the provision of an extension, which is preferred is releasably connectable to the ramp, this goes over an obtuse angle into the actual ramp and ensures a continuous drive-on area in the area or the like between the transverse lane. and the one on the street canal adjacent area.

In der Praxis hat es sich als besonders wirksam erwiesen, wenn die Auffahrplatte mit der Straßenkanalsohle, wie an sich bekannt, einen Winkel von etwa 20° einschließt.In practice, it has proven to be particularly effective if the ramp with the street channel sole, as such known, includes an angle of about 20 °.
