Description
Textilmatte fur die Begrünung von mutterbodenlosen ErdoberflächenTextile mat for greening soil surfaces without topsoil
Die Erfindung bezieht sich auf eine Textilmatte aus vorwiegend verrottenden Faserstoffen mit einer wellenförmig strukturierten Oberfläche, bestehend aus einem durch Faden- oder Fasernähte verbundenem Mehrschichtelement mit im Querschnitt eingelagerten nichttextilen Funktionselementen, wie Pflanzensamen, Wasserspeicher oder Düngemittel, welche für die Begrünung von Bauwerken ohne mutterbodenhaltiger Erdoberfläche optimale Bedingungen für den Bewuchs, die erforderliche Bewässerung und die optische Ansicht aufweist.The invention relates to a textile mat made of predominantly rotting fiber materials with a wave-shaped structured surface, consisting of a multi-layer element connected by thread or fiber seams with non-textile functional elements embedded in the cross-section, such as plant seeds, water reservoirs or fertilizers, which has optimal conditions for the growth, the necessary irrigation and the optical appearance for the greening of buildings without a topsoil-containing earth surface.
Bekannt sind textile Mehrschichtelemente für die Armierung und Begrünung von Flächen, welche aus einer festigkeitstragenden Schicht, einer mittleren Speicherschicht mit Samen und Nährstoffen sowie einer Schutzschicht bestehen. An steilen Böschungen über 50 Grad läuft das zur Bewässerung des Samens und der Pflanzen aufgebrachte Wasser bei diesen Mehrschichtelementen sehr schnell ab, so daß nur wenig Feuchtigkeit in das darunterliegende Erdreich und damit in die Zone der Pflanzenwurzeln eindringen kann.Textile multi-layer elements are well-known for reinforcing and greening surfaces. These consist of a load-bearing layer, a middle storage layer with seeds and nutrients, and a protective layer. On steep slopes of more than 50 degrees, the water used to irrigate the seeds and plants runs off very quickly with these multi-layer elements, so that only a small amount of moisture can penetrate into the soil below and thus into the zone of the plant roots.
Weiterhin sind textile Gittermatten für den Schutz und die Begrünung von erosionsgefahrdeten Bodenschichten bekannt, bei der textile Streifen zu einem mattenartigen Bewehrungsgitter verbunden und im Unterboden verankert sind. Die oberen Konturen dieser Bewehrungsgitter werden mit einem schmalen Saatgutstreifen versehen, was das Auslegen der Matte in der vegetationsarmen Zeit bzw. ein späteres Begrünen der vorgesehenen Fläche nicht ermöglicht.Furthermore, textile grid mats are known for the protection and greening of soil layers at risk of erosion, in which textile strips are connected to form a mat-like reinforcement grid and anchored in the subsoil. The upper contours of these reinforcement grids are provided with a narrow seed strip, which makes it impossible to lay out the mat during periods of low vegetation or to green the intended area later.
In G 92 12 454.2 wird eine textile erosionsschützende Begrünungsmatte beschrieben, die aus einem Mehrschichtelement aus verrottbaren Sekundär- und Flachsfasern besteht, keinen Pflanzensamen enthält und für das nachträgliche oberflächliche Aufbringen des Pflanzensamens eine geeignete Oberflächenstruktur aufweist.G 92 12 454.2 describes a textile erosion-protecting greening mat which consists of a multi-layer element made of degradable secondary and flax fibres, contains no plant seeds and has a suitable surface structure for the subsequent superficial application of the plant seeds.
In der DE 41 35 714 wird eine wasserspeichernde Bodenschutz- und Erosionsschutzmatte beschrieben, die vorwiegend aus Kokosfasern, Strohhäcksel und Textilfasern besteht, in die flächig Wasserspeichermittel eingelagert sind.DE 41 35 714 describes a water-storing soil protection and erosion control mat, which consists mainly of coconut fibres, straw chips and textile fibres, into which water storage agents are embedded over a large area.
Der im Anspruch angegebenen Erfindung liegt das Problem zugrunde, eine Textilmatte zu schaffen, mit der sowohl in der vegetationsgünstigen als auch in der vegetationsungünstigenThe invention specified in the claim is based on the problem of creating a textile mat with which both in the vegetation-favorable and in the vegetation-unfavorable

Zeit ebene geneigte Flächen ohne Mutterbodenoberfläche bzw. ohne zusätzlichen Mutterbodenauftrag sicher begrünt und Böschungen erosionssicher bebaut werden.Time, flat, inclined surfaces without topsoil surface or without additional topsoil application can be safely planted with greenery and slopes can be built on in an erosion-proof manner.
Erfindungsgemäß wird dies dadurch erreicht, daß die mittlere Schicht des Mehrschichtelementes mit einem Gewicht von mindestens 400 g/m2 vorwiegend verrottbare Fasern aufweist und darin direkt bei der Schichtbildung Pflanzensamen, Wasserspeicherelemente und gegebenenfalls Langzeitdünger eingestreut werden. Diese schwere Faserschicht wird mit einer netzähnlichen, als Festigkeitsträger wirkende Unterschicht und einer aus einem 15 -40 g/m2 schweren, grasgrünen Obervlies durch Faden- oder Faserbüschelnähte verbunden, wobei durch diese steppnahtartige Verbindung eine quer zur Herstellungsrichtung orientierte wellenförmige Oberfläche entsteht. Auch diese Faserbüschelnähte bestehen zu einem hohen Anteil aus verrottbaren Faserstoffen.According to the invention, this is achieved in that the middle layer of the multi-layer element with a weight of at least 400 g/m 2 has predominantly decomposable fibers and plant seeds, water storage elements and, if necessary, long-term fertilizer are scattered into it directly during layer formation. This heavy fiber layer is connected to a net-like lower layer that acts as a reinforcement and a grass-green upper fleece weighing 15-40 g/m 2 by thread or fiber tuft seams, whereby this quilting-like connection creates a wavy surface oriented transversely to the direction of production. These fiber tuft seams also consist to a high extent of decomposable fibers.
Faserstoffe, wie Wolle, Zellwolle, Flachs, Hanf, Kenaf, Nessel, Jute, Ramie, Kokos, Sisal u. a. verrotten beim Einsatz im Freien, sie setzen dabei Nährstoffe frei, die als Bodenverbesserungs- und Reservenährstoff wirken und die das Wachstum der die natürliche Begrünung übernehmenden Pflanzen fördern. Der Einsatz von 20 - 50 g/m2 Absorber beschleunigt den Keim- und Anwuchsvorgang erheblich, reduziert wesentlich den Wasserverlust der Matte auf großen Neigungen und bewirkt einen relativ gleichmäßigen Bewuchs. Der Absorber ist in der Lage, die Matte über mehrere Tage feucht zu halten. Dadurch bewirkt er zusätzlich eine Beschwerung der Matte, die dem Hinterlüften entgegenwirkt. Die Lage des Saatgutes im oberen Querschnittsdrittel der Matte ist optimal. Zum einen ist die bodennahe Lage des Wasserspeichers von Vorteil, da durch die Kapillarität ständig Bodenfeuchte dorthin gelangt. Zum anderen hat der Keimling der Mattenoberfläche nur eine geringe Schichtstärke zu durchstoßen, bis er das energiespendende Tageslicht erreicht. Damit gewährleistet diese textile Matte durch den konstruktiven Aufbau, die Faserstoffzusammensetzung, die enthaltenen Funktionselemente und die Oberflächenstruktur auch im stark geneigten Einbau einen hochwirksamen Erosionsschutz bis zum Wirksamwerden der natürlichen Begrünung und ein Keimen, Anwachsen und Wachsen des enthaltenen Pflanzensamens bei mutterbodenloser Erdoberfläche.Fibres such as wool, rayon, flax, hemp, kenaf, nettle, jute, ramie, coconut, sisal etc. rot when used outdoors, releasing nutrients that act as soil improvers and reserve nutrients and promote the growth of the plants that take over the natural greening. The use of 20 - 50 g/m 2 absorber accelerates the germination and growth process considerably, significantly reduces the water loss from the mat on steep slopes and results in relatively even growth. The absorber is able to keep the mat moist for several days. This also weighs down the mat, which counteracts rear ventilation. The position of the seed in the upper third of the cross-section of the mat is optimal. On the one hand, the position of the water reservoir close to the ground is an advantage, as soil moisture constantly reaches it through capillarity. On the other hand, the seedling only has to penetrate a small layer of the mat surface before it reaches the energy-giving daylight. This textile mat, thanks to its structural design, fiber composition, functional elements and surface structure, ensures highly effective erosion protection even when installed at a steep incline until natural vegetation takes effect and the germination, growth and development of the plant seeds contained in it when the surface of the earth is devoid of topsoil.
Die Erfindung wird anhand eines bevorzugten Ausführungsbeispieles weiter erläutert und beschrieben. Die dazugehörige Zeichnung zeigt einen Querschnitt der erfindungsgemäßen Textilmatte für die Begrünung mutterbodenloser Erdoberflächen aus drei Schichten 1, 2 undThe invention is further explained and described using a preferred embodiment. The accompanying drawing shows a cross section of the textile mat according to the invention for the greening of soil surfaces without topsoil, consisting of three layers 1, 2 and
3, die miteinander durch Faden- oder Fasernähte zu einem textlien Mehrschichtelement verbunden sind. Die Unterschicht 1 dient als festigkeitsgebender Träger und wird beispielsweise von einem Gewebe aus Jute gebildet, das gleichzeitig eine durchwurzelbare offene, netzartige Struktur aufweist. Auf dieser Trägerschicht 1 ist die Mittelschicht 2 angeordnet, die aus einem Faservlies aus vorwiegend verrottbaren Fasern mit einer Flächenmasse von mindestens 400 g/m2 besteht. Innerhalb der Mittelschicht 2 sind Funktionselemente, beispielsweise Saatgut 4, sowie Wasserspeicherelemente 5 und gegebenenfalls Dünger 6 eingelagert, wobei diese Funktionselemente 4, 5 und 6 direkt bei der Herstellung des die Mittelschicht 2 bildenden Faservlieses eingestreut werden. Die auf der Mittelschicht 2 vorhandene Deckschicht 3 wird von einem dünnen Vlies aus einer grasgrünen Fasermischung mit einer Flächenmasse von beispielsweise 15-40 g/m2 gebildet. Die Trägerschicht 1, die Mittelschicht 2 und die Deckschicht 3 sind im Ausfuhrungsbeispiel durch Faserbüschelnähte miteinander verbunden, die ebenfalls zu einem hohen Anteil aus verrottbaren Faserstoffen bestehen. Die steppnahtartige Verbindung aller drei Schichten bewirkt eine quer zur Herstellungsrichtung orientierte wellenartige Oberfläche, bei der in den Wellentälern wasserspeichernde und wasserstauende .Wirkungslinien 7 im Abstand von beispielsweise 20 bis 50 mm vorhanden sind. '3, which are connected to one another by thread or fiber seams to form a textile multi-layer element. The lower layer 1 serves as a strength-giving carrier and is formed, for example, from a fabric made of jute, which at the same time has an open, net-like structure that can be penetrated by roots. The middle layer 2, which consists of a fiber fleece made of predominantly decomposable fibers with a surface mass of at least 400 g/m 2 , is arranged on this carrier layer 1. Functional elements, for example seed 4, as well as water storage elements 5 and, if necessary, fertilizer 6, are stored within the middle layer 2, whereby these functional elements 4, 5 and 6 are scattered directly during the production of the fiber fleece forming the middle layer 2. The cover layer 3 on the middle layer 2 is formed by a thin fleece made of a grass-green fiber mixture with a surface mass of, for example, 15-40 g/m 2 . In the example, the carrier layer 1, the middle layer 2 and the cover layer 3 are connected to one another by fiber tuft seams, which also consist to a large extent of degradable fiber materials. The quilted seam-like connection of all three layers creates a wave-like surface oriented transversely to the direction of production, in which water-storing and water-retaining 'action lines 7' are present in the wave valleys at a distance of, for example, 20 to 50 mm.
