Description

Stützband zur Sicherung von Böschungsdecken gegen AbrutschenSupport tape to secure embankment ceilings against slipping
Die Erfindung bezieht sich auf ein Stützband zur Sicherung von Böschungs¬ decken gegen Abrutschen, welches auf der schrägen Böschungsoberfläche vor dem Aufschütten des Böschungsdeckenmateriais, insbesondere einer die Bepflanzung erlaubenden Erde, mittels Pflöcken hochkant auf stellbar ist, insbesondere unter Ausbildung eines die Böschungsoberfiäche überziehen¬ den Gitters.The invention relates to a support band for securing embankment ceilings against slipping, which can be set upright on the inclined embankment surface before the embankment ceiling material is poured on, in particular an earth that allows planting, by means of pegs, in particular with the formation of a covering of the embankment surface Grid.
Es ist bekannt, natürliche und künstliche Böschungen zur Befestigung und zum Erosionsschutz oder zur Bepflanzung, was nach einem gewissen Pflanzen¬ wachstum ebenfalls zu einer Befestigung und einem Erosionsschutz führt, mit einer Böschungsdecke zu versehen. In großem Umfang wird beispiels¬ weise bei Böschungen neben Autobahnen und Landstraßen eine bepflanzte Böschungsdecke vorgesehen.It is known to provide natural and artificial embankments for attachment and for protection against erosion or for planting, which after a certain plant growth also leads to attachment and protection against erosion, with an embankment cover. For example, in the case of embankments, in addition to motorways and country roads, a planted embankment cover is provided.
Diese Böschungsdecken müssen gegen Abrutschen auf der schrägen Böschungs¬ oberfläche, auf welche das körnige Böschungsdeckenmateriai aufgebracht worden ist, gesichert werden, und zwar auch die bepflanzten Böschungsdecken zumindest so lange, bis die Pflanzen bzw. deren Wurzeln die innere Verbin- düng der Böschungsdecke in sich und die Verbindung der Böschungsdecke mit der Böschungsoberfläche gewährleisten, welche das Abrutschen derThese embankment ceilings must be secured against slipping on the inclined embankment surface to which the granular embankment ceiling material has been applied, and also the planted embankment ceilings at least until the plants or their roots have the internal connection of the embankment ceiling and ensure the connection of the embankment ceiling to the embankment surface, which prevents the
I aus einer die Bepflanzung erlaubenden Erde bestehenden Böschungsdecke auf der Böschungsoberfläche verhindert. Insbesondere bei länger andauernden und/oder starken Regenfällen ist die Gefahr groß, daß Böschungsdeckenmate- rial weggespült wird und ein Böschungsdeckenabrutschen erfolgt» Für diese Böschungsdeckenabrutschsicherung hat man bereits Stützbänder entwickelt, welche aus mehreren zueinander parallelen Einzelbändern aus Kunststoff oder aus solchen Einzelbändern und einem um dieselbe herumge¬ wickelten weiteren Einzelband aus Kunststoff bestehen und auf der mit der Böschungsdecke zu versehenden Böschungsoberfläche mittels Pflöcken, welche in die Böschungsoberfläche im wesentlichen vertikal eingetrieben werden, hochkant aufgestellt werden, um ein die Böschungsoberfläche über¬ ziehendes Gitter zu bilden, wonach das Böschungsdeckenmaterial, für eine zu bepflanzende Böschungsdecke eine geeignete Erde, auf die Böschungs- Oberfläche aufgeschüttet, verteilt und eingeebnet wird, so daß das Stützband¬ gitter in die so erhaltene Böschungsdecke eingebettet ist und sie auf der schrägen Böschungsoberfläche abstützt (DE-A 2 . .6 202, DE-U 75 29 025).I prevented from embankment on the embankment surface consisting of a soil that allows the planting. Particularly in the case of prolonged and / or heavy rainfall, there is a great risk that the slab material will be washed away and the slab will slide off » Support tapes have already been developed for this embankment slip protection, which consist of a plurality of individual strips of plastic parallel to one another or of such individual strips and a further individual strip of plastic wrapped around them, and on the embankment surface to be provided with the embankment cover by means of pegs which extend into the surface of the embankment be driven vertically, be placed upright to form a grid covering the slope surface, after which the slope cover material, suitable soil for a slope cover to be planted, is heaped onto the slope surface, distributed and leveled, so that the support band grid is embedded in the embankment slab thus obtained and supports it on the sloping embankment surface (DE-A 2 .6 202, DE-U 75 29 025).
Diese bekannten Stützbänder aus Kunststoff sind insbesondere aus Gründen des Umweltschutzes unerwünscht, da sie in der Böschungsdecke Fremdkörper darstellen und nicht verrotten, was im übrigen auch später etwa erforderliche Abbau-, Änderungs- und Erneuerungsarbeiten an der Böschungsdecke und an der Böschung • erschwert. Auch sind die Einzelbänder weder luft- noch wasserdurchlässig oder -aufnahmefähig. Die Montage der Stützbänder ist trotz gewisser Vereinfachungen immer noch verhältnismäßig arbeitsaufwendig.These known plastic support straps are undesirable, particularly for reasons of environmental protection, since they represent foreign bodies in the embankment ceiling and do not rot, which, moreover, also complicates any necessary dismantling, modification and renewal work on the embankment ceiling and the embankment. The individual tapes are neither permeable to air nor water, nor are they absorbable. The assembly of the support straps is still relatively labor intensive, despite certain simplifications.
Dasselbe gilt für später entwickelte und bekannt gewordene Böschungsdecken- abrutschsicherungen, wobei alte Kraftfahrzeugreifen bzw. ringförmige Form¬ körper aus fäulnisbeständigem Material, insbesondere Kunststoff, in die Böschungsdecke eingebettet werden, weiche vor dem Aufschütten des Bö¬ schungsdeckenmaterials, insbesondere einer die Bepflanzung erlaubenden Erde, auf die schräge Böschungsoberfläche gelegt und aneinander bzw. an¬ einander sowie mittels Einschlagankern an der Böschungsober läche befestigt werden (DE-U 75 32 957 und 76 39 78 .).The same applies to embankment slip protection devices that were later developed and become known, whereby old motor vehicle tires or ring-shaped molded bodies made of putrefaction-resistant material, in particular plastic, are embedded in the embankment cover, which are soft before the embankment cover material is poured on, in particular an earth that allows planting, placed on the inclined surface of the embankment and fastened to one another or to one another and to the surface of the embankment by means of impact anchors (DE-U 75 32 957 and 76 39 78).
Man verwendet daher nach wie vor zur Böschungsdeckenabrutschsicherung insbesondere bei Böschungen neben Autobahnen und Landstraßen, welche bei einer Steigung von 1 : 1,5 eine Höhe von 20 bis 25 m erreichen können, geflochtene Reisigzäune. Reisig steht allerdings nicht zu allen Jahreszeiten immer in ausreichendem Maß zur Verfügung- und kann nur mit verhältnismäßig großem Aufwand in ausreichender Menge gelagert werden. Auch ist der Transport zum Einsatzort einigermaßen aufwendig, ebenso wie das Flechten der Reisigzäune verhältnismäßig viel Arbeitsaufwand sowie geschultes Perso¬ nal erfordert und kostspielig ist, was auch bei später etwa erforderlich wer- denden Reparaturen ins Gewicht fällt.Braided brushwood fences are therefore still used to protect the slab from slipping, especially on embankments next to highways and country roads, which can reach a height of 20 to 25 m on a slope of 1: 1.5. However, brushwood is not always sufficiently available in all seasons - and can only be used proportionately great effort to be stored in sufficient quantities. Also, the transport to the place of use is somewhat complex, just as the braiding of the fences requires a relatively large amount of work and trained personnel and is costly, which is also important for repairs that may become necessary later.
In der Regel werden die Reisigzäune in Form eines Gitters mit quadratischen Maschen aufgestellt, deren beide Diagonalen parallel zum Böschungsfuß bzw. zur Böschungsfallinie verlaufen. Die Reisigzäune werden hergestellt, indem man entlang der Gitterlinien in bestimmten Abständen, im allgemeinen solchen von etwa 30 cm Länge, Holzpflöcke vertikal in die abzudeckende schräge Böschungsoberfläche einschlägt und das Reisig um dieselben herum flechtet. Dann wird als Böschungsdeckenmaterial eine geeignete Erde aufge¬ schüttet, verteilt und eingeebnet, so daß sie die von den geflochtenen Rei- sigzäunen gebildeten Gitter maschen ausfüllt und sich eine etwa 20 cm hohe Böschungsdecke ergibt, die danach bepflanzt wird.As a rule, the brushwood fences are set up in the form of a grid with square meshes, the two diagonals of which run parallel to the foot of the embankment or to the line of the embankment. The brushwood fences are made by driving wooden pegs vertically into the sloping surface of the slope to be covered along the grid lines at certain intervals, generally about 30 cm in length, and braiding the brushwood around them. A suitable soil is then heaped up, distributed and leveled as the embankment ceiling material, so that it fills the mesh formed by the braided climbing fences and results in an approximately 20 cm high embankment ceiling which is then planted.
Insbesondere bei länger andauernden und/oder starken Regenfällen gewährlei¬ sten weder die Reisigzäune noch die Stützbänder aus Kunststoff, welche die Reisigzäune ersetzen sollten, eine zuverlässige Böschungsdeckenabrutsch- sicherung. Vor allem sind sie nicht in der Lage, das Wegschwemmen von Böschungsdeckenmaterial immer sicher zu verhindern.In particular in the case of prolonged and / or heavy rainfalls, neither the brushwood fences nor the plastic support bands, which were to replace the brushwood fences, guarantee reliable slope protection against slippage. Above all, they are not always able to safely prevent the slope material from being washed away.
Der Erfindung liegt die Aufgabe zugrunde, ein Stützband zur Sicherung von Böschungsdecken gegen Abrutschen der eingangs angegebenen Art zu schaffen, welches außerordentlich einfach und schnell auf der schrägen Böschungsober¬ fläche aufgebaut werden kann und auch später etwa erforderlich werdende Reparaturen an der Stützbandanordnung zur Sicherung der Böschungsdecke gegen Abrutschen auf der Böschungsoberfläche außergewöhnlich einfach und schnell durchzuführen erlaubt, bei verhältnismäßig hoher Festigkeit und zum Zurückhalten der körnigen Böschungsdecke ausreichender Dichte eine außerordentlich gleichmäßige und gleichbleibend hoher Luft- sowie Wasserdurchlässigkeit und -aufnähme- sowie -Speicherfähigkeit aufweist, so daß es aufgrund dieses außerordentlich hohen Wasseraufnahme- und -speichervermögens einer unzulässig hohen, das Wegschwemmen der Böschungs- decke bewirkenden Wasseraufnahme der Böschungsdecke auch bei länger andauernden und/oder starken Regenfällen entgegenwirkt, und ohne umwelt¬ belastende Nachwirkungen in die Böschungsdecke eingebracht werden und auch verrotten kann.The invention has for its object to provide a support band for securing embankment ceilings against slipping of the type specified above, which can be built up extremely easily and quickly on the inclined embankment surface and also later necessary repairs to the support band arrangement to secure the embankment ceiling against slipping on the surface of the embankment extremely easy and quick to carry out, with relatively high strength and sufficient density to retain the granular embankment cover, an extraordinarily uniform and consistently high air and water permeability and absorption and storage capacity, so that it is extremely high due to this Water absorption and storage capacity of an impermissibly high level, washing away the embankment counteracting water absorption of the embankment cover, even in the case of prolonged and / or heavy rainfall, and can be introduced into the embankment cover without any harmful after-effects and can also rot.

Gemäß Fig. 2 besteht die Stützbandanordnung 5 aus mehreren Stützbändern 10 und Pflöcken 11, welche etwa vertikal in die Böschungsoberfläche 3 einge¬ schlagen und an denen die Stützbänder 10 befestigt sind. Die Stützbänder 10 bilden auf der Böschungsoberfläche 3 ein Gitter mit quadratischen Ma¬ schen, welche eine Seitenl nge von etwa 3 m aufweisen können und deren beide Diagonalen parallel zum Böschungsfuß bzw. zur Böschungsfallinie verlaufen. Jeder Maschenecke ist ein Pflock 11 zugeordnet. Zwischen den beiden Eckpflöcken 11 jeder Maschenseite sind drei weitere Pflöcke 11 vorge- sehen, und zwar in gleichmäßiger Verteilung, so daß die Pflöcke 11 also in Abständen von etwa 75 cm angeordnet sind.2, the support band arrangement 5 consists of a plurality of support bands 10 and pegs 11, which strike approximately vertically into the slope surface 3 and to which the support bands 10 are fastened. The support bands 10 form on the slope surface 3 a grid with square meshes, which can have a side length of approximately 3 m and the two diagonals of which run parallel to the slope foot or the slope fall line. A peg 11 is assigned to each mesh corner. Three further pegs 11 are provided between the two corner pegs 11 on each side of the stitch, in a uniform distribution, so that the pegs 11 are thus arranged at intervals of approximately 75 cm.
Die Stützbänder 10 verlaufen jeweils zick-zack-förmig zwischen den beiden nicht dargestellten, seitlichen Böschungsenden, also zwischen der linken und der rechten Seite von Fig. 2, wobei sie sich hochkant an der Böschungs¬ oberfläche 3 entlang erstrecken und aneinander benachbarte StützbänderThe support straps 10 each run in a zigzag shape between the two sides of the slope, not shown, that is, between the left and the right side of FIG. 2, wherein they extend upright along the surface 3 of the slope and adjacent support straps

Zusätzlich ist das Gewebe 20 durch Einlagen 25, insbesondere solche aus Stahldraht oder Peddigrohr, verstärkt.As indicated in FIG. 1 and can be seen particularly clearly from FIG. 3, the support belts 10 each consist of a fabric 20 with warp threads 21 and weft threads 22, which has a plain weave, which provides high strength and high stability, and which is provided with leno strips 23 and 2, which further increase the strength and stability and ensure that the warp threads 21 cannot fray. In addition, the fabric 20 is reinforced by inlays 25, in particular those made of steel wire or rattan.
Gemäß Fig. 3 sind die Kettfäden 21 des bandförmigen Gewebes 20 mit einer Breite von etwa 20 cm in Gruppen A angeordnet, welche sich im Ab¬ stand voneinander parallel zueinander in Längsrichtung des bandförmigenAccording to FIG. 3, the warp threads 21 of the band-shaped fabric 20 with a width of about 20 cm are arranged in groups A, which are spaced apart parallel to one another in the longitudinal direction of the band-shaped
II.
Gewebes 20 erstrecken, so daß sich in demselben entsprechend verlaufende Reihen B von größeren Durchbrüchen 26 ergeben.Extend fabric 20 so that there are correspondingly extending rows B of larger openings 26 in the same.
Zur Befestigung der aus dem Gewebe 20 bestehenden Stützbänder 10 an den Pflöcken 11 ist das Gewebe 20 mit Schlaufen 27 versehen, welche jeweils von einem Kettfaden 21 gebildet sind und in eine schräg abfallende Quernut 28 eines Pflocks 11 auf dessen dem zugehörigen Stützband 10 abgewandter Seite eingehängt werden, wie Fig. 3 zeigt.To attach the support straps 10 made of the fabric 20 to the pegs 11, the fabric 20 is provided with loops 27, each of which is formed by a warp thread 21 and is suspended in an obliquely sloping transverse groove 28 of a peg 11 on its side facing away from the associated support tape 10 3, as shown.
Die Kettfäden 21 und die Schußfäden 22 des Gewebes 20 bestehen aus Garn, welches aus Fasermaterial pflanzlichen Ursprungs hergestellt ist. Ein solches Fasermaterial pflanzlichen Ursprungs kann auch noch auf das Gewebe 20 aufgenadelt werden, um einen florartigen Überzug zu bilden, was insbesondere einem erhöhten Wasseraufnahme- und -speichervermögen zugute kommt.The warp threads 21 and the weft threads 22 of the fabric 20 consist of yarn which is made from fiber material of vegetable origin. Such fiber material of plant origin can also be needled onto the fabric 20 in order to form a pile-like covering, which is particularly beneficial for increased water absorption and storage capacity.
Als Fasermaterial kommen vor allem pflanzliche Hart- oder Bastfasern, Süßgras- oder Sauergrasfasern, Seegrasfasern, Binsenfasern oder ein Gemisch dieser Fasern in Betracht, insbesondere Kokosfasern, da daraus hergestellte Garne sich durch hohe Festigkeit und Fasrigkeit auszeichnen. Statt dessen oder in Verbindung damit können jedoch beispielsweise auch Agaven-, insbe¬ sondere Sisai-, Kantala- oder Henequen-, Bananen-, insbesondere Manila-, oder Neuseeland-, Hanf-, Jute-, Ramie-, Sunn-, Kenaf-, Urena-, Rosetta-, Aloe-, Getreidestroh-, Riedgras-, Espartograsfasern oder ein Gemisch dieser Fasern als Fasermaterial verwendet werden. Die Einstellung bzw. Fadendichte des Gewebes 20 wird entsprechend der Korngrößenverteilung des Böschungsdeckenmaterials gewählt, um einerseits ein einwandfreies Einfüllen des körnigen Böschuπgsdeckenmaterials in die Gittermaschen der Stützbandanordnung 5 und möglichst günstige Verhält¬ nisse für das Wurzelwachstum der Bepflanzung der Böschungsdecke 6 zu gewährleisten und andererseits zu verhindern, daß das Böschungsdeckenmate¬ rial durch das Gewebe 20 hindurchtritt, wenn die Böschungsdecke 6 verhält¬ nismäßig viel Wasser aufgenommen hat und relativ dünnflüssig ist.Vegetable hard or bast fibers, sweet grass or sour grass fibers, sea grass fibers, rush fibers or a mixture of these fibers, in particular coconut fibers, are particularly suitable as the fiber material, since yarns produced therefrom are distinguished by high strength and flexibility. Instead of this or in connection with this, however, agave, in particular sisai, kantala or henene, banana, in particular manila, or new zealand, hemp, jute, ramie, sun, kenaf, , Urena, Rosetta, Aloe, grain straw, sedge grass, esparto grass fibers or a mixture of these fibers can be used as the fiber material. The setting or thread density of the fabric 20 is chosen in accordance with the grain size distribution of the embankment cover material, in order to ensure, on the one hand, that the granular embankment cover material is properly filled into the mesh of the support band arrangement 5 and that the conditions for the root growth of the plantation of the embankment cover 6 are as favorable as possible and, on the other hand, to prevent it that the embankment cover material passes through the fabric 20 when the embankment cover 6 has taken up a relatively large amount of water and is relatively thin.
Die Stützbänder 10 können ohne umweltbelastende Nachwirkungen in die Böschungsdecke 6 eingebracht werden und darin verbleiben, um im Laufe der Zeit zu verrotten, weisen bei hoher Festigkeit eine sehr gleichmäßige und gleichbleibend hohe Luft- sowie Wasserdurchlässigkeit und ein sehr hohes Luft- sowie Wasseraufnahme- und -speichervermögen auf und können sehr einfach und schnell mit Hilfe der Pflöcke 11, welche vorzugsweise aus Holz bestehen, an der Böschung 2 angebracht werden, wobei sich eben¬ falls vorteilhaft auswirkt, daß nur relativ wenige Pflöcke 11 in verhältnis¬ mäßig großen Abständen eingeschlagen zu werden brauchen. Ebenso einfach und schnell läßt sich die Stützbandanordnung 5 bei Beschädigungen der Stütz¬ bänder 10 reparieren. Da die Stützbänder 10 im Laufe der Zeit verrotten, kann die Stützbandanordnung 5 spätere Abbau-, Änderungs- und Erneuerungs¬ arbeiten an der Böschungsdecke 6 und an der Böschung 2 nicht behindern.The support straps 10 can be introduced into the embankment cover 6 without any environmentally harmful after-effects and remain therein in order to rot over time. storage capacity and can be attached very easily and quickly to the embankment 2 with the aid of the pegs 11, which are preferably made of wood, whereby it is also advantageous that only relatively few pegs 11 are driven in at relatively large intervals need. The support band arrangement 5 can be repaired just as easily and quickly if the support bands 10 are damaged. Since the support belts 10 rot over time, the support belt arrangement 5 cannot hinder subsequent dismantling, modification and renewal work on the embankment ceiling 6 and on the embankment 2.
Das dargestellte und geschilderte Gewebe 20 sowie die dargestellte und geschilderte Stützbandanordnung 5 können in vielfacher Hinsicht abgeändert werden. So muß das Gewebe 20 nicht unbedingt einen aufgenadelten Flor aus Fasermaterial pflanzlichen Ursprungs aufweisen, kann es statt der Lein¬ wandbindung mit einer anderen Bindung, beispielsweise einer Köperbindung, versehen sein, können die Dreherleisten 23 sowie 2 . fehlen, ebenso wie die verstärkenden Einlagen 25, und ist auch die gruppenweise Anordnung der Kettfäden 21 des Gewebes 20 nicht immer erforderlich. Die Schlaufen 27 des Gewebes 20 zur Stützbandbefestigung an den Pflöcken 1 1 müssen gleichfalls nicht unbedingt von den Kettfäden 21 des Gewebes 20 gebildet sein und können sogar ganz fehlen, wenn eine andere Stützbandbefestigung gewählt wird, wie beispielsweise das Antackern oder Anrödeln der Stützbän- der 10 an die Pflöcke 11. Die Breite des Gewebes 20 ist nicht auf eine solche von etwa 20 cm beschränkt.The illustrated and described fabric 20 and the illustrated and described support band arrangement 5 can be modified in many ways. Thus, the fabric 20 does not necessarily have to have a needled pile of fiber material of vegetable origin; instead of the plain weave, it can be provided with another weave, for example a twill weave, the leno strips 23 and 2. are missing, as are the reinforcing inserts 25, and the grouped arrangement of the warp threads 21 of the fabric 20 is not always necessary. The loops 27 of the fabric 20 for attaching the support band to the stakes 11 likewise do not necessarily have to be formed by the warp threads 21 of the fabric 20 and may even be completely absent if a different support tape attachment is selected, such as, for example, the tacking on or loosening of the support tapes. 10 to the pegs 11. The width of the fabric 20 is not limited to that of about 20 cm.
Auch die Stützbandanordnung 5 kann anders ausgebildet werden. Beispielswei- se können die Stützbänder 10 ausschließlich parallel zum Böschungsfuß ver¬ laufend oder ausschließlich schräg zur Böschungsfallinie verlaufend oder derart angeordnet werden, daß sich auf der schrägen Böschungsoberfläche 3 ein Gitter mit quadratischen Maschen ergibt, deren Seiten parallel zum Böschungsfuß bzw. zur Böschungsfallinie verlaufen. Auch können die Gitter- maschen statt quadratisch zu sein eine andere Gestalt aufweisen, beispiels¬ weise rechteckig oder dreieckig sein. Die Pflöcke 11 müssen nicht unbedingt aus Holz bestehen, sondern es ist auch denkbar, Stahl- oder Kunststoffpflöcke 11 zu verwenden, ebenso wie die Quernuten 28 der1 Pflöcke 11 anders ausge¬ bildet oder durch andere Halterungen für die Stützbänder 10, wie beispiels- weise Haken, ersetzt werden können. The support band arrangement 5 can also be designed differently. For example, the support strips 10 can run exclusively parallel to the slope foot or run exclusively at an angle to the slope fall line or in such a way that a grid with square meshes results on the slope slope surface 3, the sides of which run parallel to the slope foot or slope slope line. Instead of being square, the mesh can also have a different shape, for example rectangular or triangular. The pegs 11 may not necessarily be made of wood, but it is also conceivable to use steel or plastic pegs 11, as well as the transverse grooves 28 of 1 pegs 11 forms different ausge¬ or other holders for the support bands 10 as beispiels- as Hook, can be replaced.
