Description

Die Erfindung betrifft eine Lärmschutzwand, mit einem von begrünbaren Gittermatten gebildeten Füllraum zur Aufnahme von bodigem Füllmaterial, das mit Trägermatten in dem Füllraum gehalten ist.The invention relates to a noise barrier, with a filling space formed by greenable grid mats for receiving bodigem filling material, which is held with support mats in the filling space.

Derartige Lärmschutzwände sind Erdbauwerke, die Wohngebiete gegenüber dem Verkehrslärm benachbarter Straßen schützen sollen. Sie bestehen üblicherweise aus einander gegenüber stehenden Gittermatten, die zwischen sich einen freien Füllraum bilden. Dieser freie Füllraum kann dann mit von vor Ort vorhandenem, erdigem Füllmaterial, beispielsweise Bodenaushub, Abraum aus dem Straßenbau oder dergleichen verfüllt werden. Anschließend werden diese Erdbauten an ihren Außenseiten mit einer biologischen Begrünung versehen.Such noise barriers are earthworks designed to protect residential areas from the traffic noise of adjacent roads. They usually consist of mutually opposed grid mats, which form a free filling space between them. This free filling space can then be filled with on-site, earthy filling material, for example excavated soil, overburden from road construction or the like. Subsequently, these earthworks are provided on their outer sides with a biological greening.

Aus der DE 94 08 184.0 ist ein Wandkörper für eine Schallschutzwand oder für die gärtnerische Gestaltung mit im Bereich der an den Stirn- und Seitenflächen des Wandkörpers angeordneten Matten bekannt, bei dem eine wasserdichte Schicht als Verdunstungsschutz mit Löchern in den Bereichen der Bepflanzung vorgesehen ist.From the DE 94 08 184.0 is a wall body for a soundproof wall or for horticultural design with known in the range of arranged on the front and side surfaces of the wall body mats, in which a waterproof layer is provided as evaporation protection with holes in the areas of the planting.

Die EP 0 100 374 A1 offenbart einen mehrschichtigen, schallabsorbierenden, mit schüttungsresistenten Pflanzen bewachsenen Aufbau. Dieser Aufbau ist hoch komplex und wenig kosteneffizient herzustellen.The EP 0 100 374 A1 discloses a multi-layered sound-absorbing structure overgrown with bulk-resistant plants. This structure is highly complex and less cost efficient to produce.

Schließlich ist in der DE 20 2004 012489 U1 noch ein Gabionenkorbsystem offenbart, dass mit Vegetationsmatten behängt werden kann.Finally, in the DE 20 2004 012489 U1 nor a gabion basket system reveals that can be hung with vegetation mats.

Die durch derartige Lärmschutzwände erreichte Schallabsorption ist stark abhängig von dem vor Ort vorhandenen Füllmaterial. Dieses Füllmaterial kann beispielsweise aus grob gebrochenem Gestein oder ähnlichem bestehen, das eine relativ geringe Schalldichtigkeit aufweist. Die Schallabsorption ist damit nicht immer in ausreichendem Maße gewährleistet. Häufig muss deshalb zusätzliches, den Verkehrslärm besser abdämmendes Füllmaterial verwendet werden, das über möglicherweise größere Strecken herbeigeschafft werden muss; dies ist zeit- und kostenintensiv.The achieved by such noise barriers sound absorption is highly dependent on the locally existing filler. This filling material may for example consist of coarsely crushed rock or the like, which has a relatively low sound-tightness. The sound absorption is thus not always guaranteed to a sufficient extent. Often, therefore, additional, better attenuating the traffic noise filling material must be used, which must be brought over possibly longer distances; This is time consuming and costly.

Aufgabe der vorliegenden Erfindung ist es, eine Lärmschutzwand der eingangs beschriebenen Art zu schaffen, mit der eine von dem verwendeten Füllmaterial unabhängige gute Schallabsorption erreicht wird.Object of the present invention is to provide a noise barrier of the type described above, with the one independent of the filler material used good sound absorption is achieved.

Gelöst wird diese Aufgabe mit einer Lärmschutzwand, mit einem von begrünbaren Gittermatten gebildeten Füllraum zur Aufnahme von bodigem Füllmaterial, das mit Trägermatten in dem Füllraum gehalten ist, in dem Füllraum eine Lärm absorbierende Dämmschicht integriert ist, die Lärm absorbierende Dämmschicht zwischen dem Füllmaterial und den Trägermatten angeordnet ist, die Dämmschicht aus einem Fasermaterial besteht und mehrlagig ausgebildet ist, und die Dicke der Dämmschicht etwa 10 bis 20mal größer als die der Trägermatte ist.This object is achieved with a noise barrier, with a formed by green grid mesh filling space for receiving bodigem filling material, which is held with support mats in the filling space, in the filling space a noise absorbing insulating layer is integrated, the noise absorbing insulating layer between the filler and the support mats is arranged, the insulating layer consists of a fiber material and is formed multi-layered, and the thickness of the insulating layer is about 10 to 20 times greater than that of the support mat.

Durch diese Maßnahmen wird eine Lärmschutzwand geschaffen, die eine eigene Schalldämmschicht aufweist. Der Mehraufwand gegenüber herkömmlichen Lärmschutzwänden ist dadurch wesentlich geringer und das Herbeischaffen von ortsfremdem, schalldämmendem Füllmaterial kann unterbleiben.Through these measures, a noise barrier is created, which has its own sound insulation layer. The extra effort compared to conventional noise barriers is thus much lower and the bringing in of local, sound-insulating filling material can be omitted.

Weitere vorteilhafte Maßnahmen sind in den Unteransprüchen beschrieben. Die Erfindung ist in der beiliegenden Zeichnung dargestellt und wird nachfolgend näher beschrieben; es zeigt:

Figur 1
die schematische Darstellung eines Straßenabschnittes mit einer Lärmschutzwand mit erfindungsgemäß integrierter Lärm-Dämmschicht;
Figur 2
den Schnitt durch eine Lärmschutzwand nach Figur 1 im Detail.
Further advantageous measures are described in the subclaims. The invention is illustrated in the accompanying drawings and will be described in more detail below; it shows:
FIG. 1
the schematic representation of a road section with a noise barrier with inventively integrated noise-insulating layer;
FIG. 2
the section through a noise barrier after FIG. 1 in detail.

Wie in der Figur 1 schematisch dargestellt ist, bestehen Lärmschutzwände 10, die den von einer Straße 18 ausgehenden Verkehrslärm von einem Wohngebiet abhalten sollen, aus einer Vielzahl von einander gegenüber gestellten Gittermatten 11, die zwischen sich einen freien Füllraum 15 bilden. Der freie Füllraum 15 wird nach dem Aufbau der Lärmschutzwand 10 mit vor Ort vorhandenem Füllmaterial 14 verfüllt, um sie orts- und standfest zu machen.Like in the FIG. 1 is shown schematically, there are noise barriers 10, which are intended to prevent the emanating from a street 18 traffic noise from a residential area, from a plurality of opposing grid mats 11, which form a free filling space 15 between them. The free filling space 15 is filled after construction of the noise barrier 10 with locally available filler 14 to make them stationary and stable.

Die Gittermatten 11 bestehen vornehmlich aus Baustahlmatten, die eine Vielzahl von Gitteröffnungen 17 aufweisen. An diesen Gitteröffnungen 17 kann eine von der jeweiligen Jahreszeit abhängige biologische Begrünung 16 an den Außenseiten der Lärmschutzwand empor ranken oder sich darin verwurzeln.The lattice mats 11 consist primarily of mild steel mats having a plurality of grid openings 17. At these grid openings 17, depending on the particular season biological greening 16 tend to rank up or root themselves on the outer sides of the noise barrier.

Wie die Figur 2 im Detail zeigt, sind hinter den Gittermatten 11, die beispielsweise aus feuerverzinktem Stahl oder Blechmaterial bestehen, Lagen einer textilen Trägermatte 12 vorgesehen. Die textilen Trägermatten 12 können beispielsweise aus einem Faservlies bestehen, das üblicherweise mit aufgesteppten Kokosfasern versehen ist.As the FIG. 2 shows in detail, layers of a textile support mat 12 are provided behind the grid mats 11, which consist for example of hot-dip galvanized steel or sheet material. The textile carrier mats 12 may for example consist of a non-woven fabric, which is usually provided with quilted coconut fibers.

Zwischen der Trägermatte 12 und dem Füllmaterial 14 ist eine erfindungsgemäß integrierte Dämmschicht 13 vorgesehen. Die integrierte Dämmschicht 13 kann ein- oder mehrlagig ausgebildet sein. Sie besteht aus einem faserigen Lärmabsorptionsmaterial oder einer Kunststoffdämmschicht. Ebenso können Steinwolle oder Textilfasern eingesetzt werden.Between the support mat 12 and the filling material 14 an inventively integrated insulating layer 13 is provided. The integrated insulating layer 13 may be formed one or more layers. It consists of a fibrous noise absorbing material or a Kunststoffdämmschicht. Likewise rock wool or textile fibers can be used.

Die zusätzliche integrierte Lärm-Dämmschicht 13 ist ca. zehn bis zwanzigmal so dick wie die Trägermatte 12. Sie gewährleistet eine gleich bleibend hohe Lärmabsorption. Die so erreichte Lärmabsorption ist unabhängig von dem verwendeten Füllmaterial 14, beispielsweise Grobschotter, Bodengemisch oder dergleichen. Auf die Anfuhr von ortsfremdem, erdigem Füllmaterial kann dadurch verzichtet werden.The additional integrated noise insulation layer 13 is about ten to twenty times as thick as the support mat 12. It ensures a consistently high noise absorption. The noise absorption achieved in this way is independent of the filling material 14 used, for example coarse gravel, soil mixture or the like. On the supply of off-site, earthy filling material can be dispensed with.
