Description

Die Erfindung betrifft eine vegetative Lärmschutzwand, mit zwischen Segmentpfosten gehaltenen, einschiebbaren Wandelementen, die mit einem Nährmedium für Pflanzen und mit einer Bewässerungsvorrichtung versehen sind.The invention relates to a vegetative noise barrier, with insertable wall elements held between segment posts, which are provided with a nutrient medium for plants and with an irrigation device.

Derartige Lärmschutzwände, wie sie zB aus der EP 0 337 082 A2 bekannt sind, dienen beispielsweise an belebten Straßen und Autobahnen dem Schallschutz für dahinter befindliche Wohngebiete. Sie bestehen im wesentlichen aus einem Traggerüst, welches mit einer Bodenhinterfüllung versehen ist, und einer niedrig wachsenden Bepflanzung. Problematisch dabei ist ihre relativ geringe landschaftsarchitektonische Gestaltungsmöglichkeit, ihre relativ schwierige Montage und die hohe Wartungsanforderung bei der Pflanzenpflege.Noise protection walls of this type, as are known, for example, from EP 0 337 082 A2, are used, for example, on busy streets and motorways to provide sound insulation for residential areas located behind them. They essentially consist of a supporting frame, which is provided with a backfill, and a low-growing planting. The problems here are their relatively low landscape architectural design options, their relatively difficult assembly and the high maintenance requirements for plant care.

Aufgabe der vorliegenden Erfindung ist es, eine Lärmschutzwand der eingangs beschriebenen Art zu schaffen, die relativ große landschaftsarchitekonische Freiheit gewährleistet, schnell und handlich montierbar ist und einen relativ geringen planzenpflegerischen Aufwand erfordert.The object of the present invention is to provide a noise barrier of the type described at the outset which ensures relatively great freedom in terms of landscape architecture, is quick and easy to assemble and requires a relatively low level of plant maintenance.

Gelöst wird diese Aufgabe dadurch, daß die Wandelemente aus Gittermatten bestehen, die auf ihren Innenseiten mit einer Krallmatte und ihren Außenseiten mit einer Verputzschicht versehen sind, die Gittermatten in den Segmentpfosten doppelwandig, einander gegenüberliegend gehalten sind, der Zwischenraum zwischen den einander gegenüberliegenden Gittermatten mit einer Substrat-füllung hinterfüllbar ist und in dem Zwischenraum längsverlaufende Leerrohre zur Aufnahme der Bewässerungsvorrichtung verlegt sind. Bei einer bevorzugten Ausführung ist es vorgesehen, daß die Gittermatten in Längsrichtung biegsam und in Vertikalrichtung biegesteif ausgebildet sind.This object is achieved in that the wall elements consist of lattice mats which have a claw mat on their inner sides and a one on their outer sides Plaster layer are provided, the lattice mats in the segment posts are double-walled, held opposite each other, the space between the opposite lattice mats can be backfilled with a substrate filling and in the space longitudinal empty pipes for receiving the irrigation device are laid. In a preferred embodiment it is provided that the grid mats are flexible in the longitudinal direction and rigid in the vertical direction.

Durch diese Maßnahmen wird eine Lärmschutzwand geschaffen, die durch die in Längsrichtung relativ biegsamen Gittermatten auch mit relativ kleinen Radien versehen aufgestellt werden kann. Dadurch werden landschaftsarchitekonische Ideen relativ leicht verwirklicht. Durch ihre Segmentbauweise können diese Elemente vorgefertigt werden, sind relativ leicht und handlich und können damit schnell und mit geringem Aufwand montiert werden.These measures create a noise protection wall, which can also be provided with relatively small radii due to the relatively flexible grid mats in the longitudinal direction. As a result, landscape architecture ideas can be realized relatively easily. Due to their segmental construction, these elements can be prefabricated, are relatively light and handy and can therefore be assembled quickly and with little effort.

Durch die in der Substratfüllung verlegten Leerrohre können Bewässerungsleitungen verlegt werden, die zu Wartungszwecken leicht ausgetauscht werden können. Dadurch ist eine schnelle und einfache Innenreinigung möglich und eine eventuelle Verschlämmung kann schnell und ohne großen Aufwand beseitigt werden. Die planzenpflegerischen Wartungsmaßnahmen können damit auf ein Minimum reduziert werden.Irrigation pipes can be laid through the empty pipes laid in the substrate filling, which can be easily replaced for maintenance purposes. This enables quick and easy cleaning of the interior and any silting can be removed quickly and without great effort. Plant maintenance measures can thus be reduced to a minimum.

Die in der Figur 1 dargestellte vegetative Lärmschutzwand 10 besteht im wesentlichen aus einer Vielzahl von geraden oder gebogenen Wandelementen 11, auf denen eine Begrünung 12 angepflanzt werden kann. Die Wandelemente 11 sind zwischen Segmentpfosten 13 gehalten.The vegetative noise barrier 10 shown in FIG. 1 essentially consists of a large number of straight or curved wall elements 11, on which a greenery 12 can be planted. The wall elements 11 are held between segment posts 13.

Wie die Figuren 2 und 3 zeigen, besteht ein Wandelement 11 im wesentlichen aus einer Gittermatte 15, beispielsweise einer handelsüblichen Baustahlmatte, die in Längsrichtung, dh an ihrer Oberkante 32 und an ihrer Unterkante 33 mit Rundelementen 18, beispielsweise dünnen Rohren oder Rundeisen begrenzt sind. Die einzelnen Wandelemente 11 werden durch die Segmentpfosten 13 gehalten, die wiederum in Fundamenten 14 eingelassen sind. Die Fundamente 14 bestehen beipielsweise aus Beton und können im Erdreich eingegraben sein.As shown in FIGS. 2 and 3, a wall element 11 essentially consists of a mesh mat 15, for example a commercially available structural steel mat, which is delimited in the longitudinal direction, ie on its upper edge 32 and on its lower edge 33 with round elements 18, for example thin tubes or round bars. The individual wall elements 11 are held by the segment posts 13, which in turn are embedded in foundations 14. The foundations 14 consist, for example, of concrete and can be buried in the ground.

Wie die Figuren 4 und 5 zeigen, bestehen die Segmentpfosten 13 aus Doppel-T-Trägern, an deren T-Stück-Hinterschneidungen 22 die vorgefertigten, auswechselbaren Wandelemente 11 abgestützt sind. Die längsverlaufenden Oberkanten 32 bzw. Unterkanten 33 der Gittermatten 15 der Wandelemente 11 sind, wie die Figur 6(C) zeigt, aus leicht biegsamen Rundmaterial oder Rohren 18 gefertigt, während die vertikal verlaufenden seitlichen Begrenzungen, wie die Figur 6(B) zeigt, aus biegesteiferen Winkeleisen 17 bestehen. Die Wandelemente 11 sind dadurch in Längsrichtung leicht biegsam, und mit ihnen können vegetative Lärmschutzwände 10 auch engster Radien geformt werden.As FIGS. 4 and 5 show, the segment posts 13 consist of double-T beams, on the T-piece undercuts 22 of which the prefabricated, exchangeable wall elements 11 are supported. The longitudinal upper edges 32 and lower edges 33 of the lattice mats 15 of the wall elements 11 are, as shown in FIG. 6 (C), made of slightly flexible round material or tubes 18, while the vertical lateral boundaries, as shown in FIG. 6 (B), from more rigid angle iron 17 exist. As a result, the wall elements 11 are slightly flexible in the longitudinal direction, and vegetative noise barriers 10, even the narrowest radii, can be formed with them.

Wie die Figur 6(A) zeigt, sind die Segmentpfosten 13 zwischen ihren T-Stück-Hinterschneidungen 22 in einem vorbestimmten Abstand mit Bohrungen 24 bzw. einer Auskehlung 23 versehen, in denen Leerrohre 25 verlegt werden können. Die Leerrohre 25 verlaufen dadurch in einer vorbestimmbaren Distanz zu den Wandelementen 11, durch sie kann die später nachgefüllte Subtratfüllung 29 bewässert werden.As FIG. 6 (A) shows, the segment posts 13 are provided with bores 24 or a groove 23 between their T-piece undercuts 22 at a predetermined distance, in which empty pipes 25 can be laid. The empty pipes 25 thereby run at a predeterminable distance from the wall elements 11, through which the substrate filling 29, which is subsequently refilled, can be watered.

Wie die Figur 7 zeigt, ist der Zwischenraum 21 zwischen den Gittermatten 15 mit einer Substratfüllung 29 hinterfüllt. Diese Substratfüllung 29 hält die Gittermatten 15 auf Distanz. Damit die Gittermatten 15 durch die Substratfüllung 29 nicht nach außen ausgebeult werden, sind, wie die Figuren 2 und 6(C) zeigen, Zuganker 20 vorgesehen, die eine vorbestimmte Länge aufweisen und durch Muttern 20a gehalten werden. Die Zuganker 20 sind etwa mittig in dem Feld eines Wandelementes 11 angeordnet.As FIG. 7 shows, the space 21 between the grid mats 15 is backfilled with a substrate filling 29. This substrate filling 29 keeps the grid mats 15 at a distance. In order that the lattice mats 15 are not bulged outwards by the substrate filling 29, tie rods 20 are provided, as shown in FIGS. 2 and 6 (C), which have a predetermined length and are held by nuts 20a. The tie rods 20 are arranged approximately centrally in the field of a wall element 11.

Wie die Figur 7 weiter zeigt sind die Gittermatten 15 an ihren Innenseiten 16 mit Krallmatten 27 belegt. Auf die Außenseiten 19 der Gittermatten 15 ist eine Verputzschicht 30 aufgetragen, die aus einem relativ hochviskosen Gemisch aus Lehm, Cellulose und Saatgut besteht. Diese Verputzschicht 30 kann wie ein normaler Putz auch an senkrechten Wänden aufgebracht werden. Durch das eingemischte Saatgut begrünt ein derartiges Wandelement 11 relativ schnell, wobei durch den Lehmbestandteil dem auflaufenden Saatgut ausreichende Feuchtigkeit, Raum zum Wachsen und guter Halt geboten wird. Der Bestandteil aus Cellulose dient in erster Linie als Armierung für den Lehm, da durch seine Fasern ein Abfließen verhindert wird und der Lehm noch eine bestimmte Plastizität beibehält. Weiterhin dient die Cellulose der gleichmäßigen Durchfeuchtung, da ihre Fasern die Eigenschaft haben, Wasser kappilar zu leiten.As FIG. 7 further shows, the mesh mats 15 are covered with claw mats 27 on their inner sides 16. A plaster layer 30, which consists of a relatively highly viscous mixture of clay, cellulose and seeds, is applied to the outer sides 19 of the lattice mats 15. This plaster layer 30 can also be applied to vertical walls like normal plaster. Such a wall element 11 greened relatively quickly due to the mixed-in seed, with the clay component providing the growing seed with sufficient moisture, space for growth and good hold becomes. The cellulose component primarily serves as a reinforcement for the clay, since its fibers prevent it from flowing off and the clay still maintains a certain plasticity. Furthermore, the cellulose is used for even wetting because its fibers have the property of conducting water capillary.

Mit der Verrottung der Cellulose und dem Wachstum des Saatgutes findet eine natürliche Wechselwirkung statt. Hat nämlich der Lehm anfangs die Aufgabe, dem Saatgut Halt und Wachstumsmöglichkeit zu geben, so haben nach dem Aufgehen die Gräser und Jungpflanzen die Aufgabe der Cellulose übernommen und bilden durch ihr Wurzelwerk sehr schnell Soden, die wiederum dem Lehm ausreichenden Halt an der relativ steil bis senkrechten Lärmschutzwand 10 bieten. Die Wurzeln der Gräser und Jungpflanzen wachsen dabei durch die Krallmatte 27 hindurch und in die Substratfüllung 29 hinein, aus der sie Nährstoff und Wasser entnehmen können. Zur ausreichenden Bewässerung der Substratfüllung 29 dienen die Leerrohre 25, in denen eine Bewässerungsvorrichtung, beispielsweise in Form von perforierten Wasserschläuchen als Tröpfchenbewässerung verlegt werden kann.A natural interaction takes place with the rotting of the cellulose and the growth of the seeds. If the clay initially has the task of giving the seed support and growth opportunity, then after it has risen, the grasses and young plants have taken over the task of cellulose and, thanks to their roots, form sodes very quickly, which in turn provide the clay with sufficient support on the relatively steep slope vertical noise barrier 10 offer. The roots of the grasses and young plants grow through the claw mat 27 and into the substrate filling 29, from which they can take nutrient and water. The empty pipes 25, in which an irrigation device, for example in the form of perforated water hoses, can be installed as drip irrigation, are used to adequately irrigate the substrate filling 29.

Die Leerrohre 25 sind gelocht und mit einer Faserummantelung 31 versehen, die einer Verschlämmung vorbeugen soll. Durch die Tröpfchenbewässerung 26 wird eine Austrocknung der Substratfüllung 29 vermieden, gleichzeitig kann durch sie eine Flüssigdüngung erfolgen. Die Bewässerungshorizonte lassen sich dabei je nach Wandstärke in ihrer Anzahl und in ihrem Abstand variieren, so daß auch schmale und schmalste Ausführungen der Lärmschutzwand 10 eine optimale Durchfeuchtung erfahren.The empty tubes 25 are perforated and provided with a fiber sheathing 31, which is intended to prevent silting. The droplet irrigation 26 prevents the substrate filling 29 from drying out, and at the same time it can be used for liquid fertilization. The irrigation horizons can vary in number and distance depending on the wall thickness, so that even narrow and narrow versions of the noise barrier 10 experience optimal moisture penetration.

Durch die Austauschbarkeit der Tröpchenbewässerung 26 ist es möglich, sämtliche Bewässerungshorizonte mit einfachen Mitteln zu warten, und bei Beschädigungen irgendeiner Art leicht auszutauschen. Der in der Verputzschicht 30 enthaltene Lehm verhindert dabei einerseits ein Austrocknen der Lärmschutzwand 10, andererseits werden starke Temperaturschwankungen vermieden, die bei flachwurzelnden Gräsern im Frühjahr zu Schaden führen könnten.Due to the interchangeability of the droplet irrigation 26, it is possible to maintain all irrigation horizons with simple means and to easily replace them in the event of damage of any kind. The clay contained in the plastering layer 30 on the one hand prevents the noise protection wall 10 from drying out, and on the other hand strong temperature fluctuations are avoided which could cause damage to flat-rooted grasses in spring.

Die Lärmschutzwand 10 kann mit den oben beschriebenen Wandelementen 11 an verschiedenen geneigten Segmentpfosten 13 bestehen. Bei der in der Figur 8 dargestellten Ausführung ist ein relativ steil stehendes Trapez vorgesehen, welches durch Quertraversen 28 auf Distanz gehalten wird und in einem Fundament 14 verankert ist.The noise barrier 10 can exist with the wall elements 11 described above on different inclined segment posts 13. In the embodiment shown in FIG. 8, a relatively steep trapezoid is provided, which is held at a distance by cross members 28 and is anchored in a foundation 14.

Bei der in der Figur 9 dargestellten Ausführung besteht die Lärmschutzwand 10 aus einem relativ breiten Trapez, welches durch ihr Eigengewicht und ihres relativ breiten Aufbaues frei aufgestellt werden kann.In the embodiment shown in Figure 9, the noise barrier 10 consists of a relatively wide trapezoid, which can be set up freely due to its own weight and its relatively wide structure.
