Abstract

Curtains are made from synthetic filaments secured as straggling loops by pricking or water proof adhesives or fusion to support fabrics which are anchored in patterns of horizontal and vertical curtains in sea water near a coastline to inhibit wave and current motions and protect the shore from erosion or to permit establishment of seaweed growth. The filaments should be buoyant, may be hollow, should be made of hydrophobic materials (polyolefins) or impregnated with water repellent materials (silicone polymer oils or emulsions). Cellular floats, pref. coloured, may be fixed at intervals in or along the curtain.

Description

Mattenbahnell aus synthetischen Fasern als Küstenschutz und zur besseren biologischen Wasserreinigung Gegenstand der Neuerung sind Mattenbahnen aus synthetischen Fasern zum Schutz von Seekiisten bzw. zur Unterstützung der biologischen Wasserreinigung in Stauseen, Wasser-Reservoiren, usw.Mattenbahnell made of synthetic fibers as coastal protection and for better biological water purification The subject of the innovation are synthetic mat sheets Fibers to protect sea skis or to support biological water purification in reservoirs, water reservoirs, etc.

Es ist bekannt, Seeküsten vor der zerstörenden Wirkung der Wellen durch Buhnenbauten, Beton-"Tetrapoden" und ähnliche Bauten zu schützen. Diese "Verbauungen" sind sehr aufwendig und werden vielfach durch Unterspülungen zerstört.It is known to sea coasts from the destructive effects of the waves to be protected by groynes, concrete "tetrapods" and similar structures. These "barriers" are very expensive and are often destroyed by underwashing.

Ferner ist bekannt geworden, Seetaiig vor der Küste anzupflanzen, wodurch der Seegang sehr beruhigt çurcle.It has also become known to plant seaweed off the coast, which makes the swell very calm çurcle.

Allein gelang diese Anpflanzung nur in Gebieten, wo der Seeboden wenigstens für längere Zeit ruhig wnr, bis die Wurzeln genügend Halt gefunden hatten. Audi dieser Weg war sehr teuer und gelang dort nicht, wo größere Strömungen durch Ebbe und Flut auftraten.But this planting was only successful in areas where the sea floor at least Keep calm for a long time until the roots have found sufficient support. Audi this route was very expensive and did not work where there were large currents due to the ebb tide and flood occurred.

Aus diesem Grund hat man "künstlichen Seetang" entwickelt, der aus zahlreichen miteinander verbundenen Polypropylenbändern besteht und den man vor der Küste mit entsprechenden Beschwerungen versenkt. Dabei hat sich gezeigt, daß sich die einzelnen "Bänder" durch den Seegang stark verfingen, miteinander verfilzten und dadurch immer lcürzer und wirkungsloser wurden.For this reason "artificial seaweed" has been developed which is made from numerous interconnected polypropylene tapes and the one before sunk in the coast with corresponding weights. It has been shown that the individual "ribbons" got tangled up in the swell, felted together and thereby became ever shorter and more ineffective.

Um diesen Schwierigkeiten sicher zu entgehen, wird erfindungsgemäß vorgeschlagen, diese "Beruhigungswiesen" nicht auf dem Meeresboden anzulegen und keine Bänder zu verwenden, sondern mattenförmige Flore (1) aus synthetischen Fasern an der Oberfläche schwimmend zu verankern. Die synthetischen Fasern sind spezifisch leichter als Wasser und treiben daher an der Wasseroberfläche. Um die wellenbrechende Wirkung zu erhöhen, sind an den horizontal liegenden Matten 1 iii Abständen 2 senkrechte Flore 3 mit Gewichtsbeschwerungen 4 und Bodenverankerungen 5 angebracht, wodurch diese Matten örtlich gebunden sind. Da sie locker gebun<leiie Flore aus vielen gekräuselten Einzelfäden und hoch flexil>el sind, kann das Wasser hindurchfließen, doch wer<leji starke Wasserbewegungen stark gebremst. Die Wellen werden gebrochen, mitgefiihrter Sand und andere Treibstoffe lagern sich ab.In order to surely avoid these difficulties, according to the invention suggested not to create these "calming meadows" on the seabed and do not use ribbons, but mat-shaped piles (1) made of synthetic fibers to be anchored floating on the surface. The synthetic fibers are specific easier than water and therefore float on the surface of the water. About the wave-breaking effect to increase, there are 2 vertical spaces on the horizontally lying mats 1 iii Piles 3 with weight weights 4 and floor anchors 5 attached, whereby these mats are locally bound. Because they were loosely tied, Flore made of many crimped single threads and are highly flexible, the water can flow through them, but who <leji strongly braked strong water movements. The waves are broken Carried sand and other fuels are deposited.

Aus diesem Grund sind derartige "Mattenfelder" vor Seebädern von großem Nutzen, da sich der feine Sand bis an den Strand schiebt, während größere Teile im Beroich der "Mattenfelder" abgelagert werden Um sie weithin erkennbar zu machen, weisen sie an ihren Außenzonen schwimmende, farbige "Bojen" 7 aus Hartschaum auf. Fig. 1 zeigt einen schematischen Sciinitt durch ein Mattenfeld. Um Bootsfahrten und die Schifffahrt nicht zu beeinträchtigen, werden für Schiffe Fahrrinnen freigehalten, für kleinere Boote dagegen nur hinreichend große Passagen 8. Dabei wird es von besonderem Vorteil sein, wenn die "Mattenfelder" mehrfach gestaffelt so angelegt werden, daß Zwischenräume für den Verkehr freibleiben und die Wellen in zunehmendem Maße beruhigt werden. Dabei ist es wichtig, diese Passagen 8 durch versetzte Mattenfelder zu versperren, um die Wellen annähernd gleichmäßig zu brechen. In Fig. 2 ist die vorgeschlagene Anordnung schematisch dargestellt. Die Mattenfelder können aus beliebig vielen Einzelbahnen zusammengesetzt werden (1a - 1k).For this reason, such "mat fields" in front of seaside resorts are of great importance Use, because the fine sand pushes up to the beach, while larger parts are deposited in the area of the "mat fields" To make them widely recognizable, if they have floating, colored "buoys" 7 made of hard foam in their outer zones. Fig. 1 shows a schematic section through a mat field. About boat trips and not to impair shipping, fairways are kept free for ships, for smaller boats, on the other hand, only sufficiently large passages 8. It is special It will be an advantage if the "mat fields" are staggered several times in such a way that Gaps remain free for traffic and the waves calmed down increasingly will. It is important to block these passages 8 with staggered mat fields, to break the waves almost evenly. In Fig. 2 is the proposed Arrangement shown schematically. The mat fields can be made up of any number of individual lanes be put together (1a - 1k).

Um die gleichen Matten auch zur besseren biologischen Reinigung in Frischwasser-Talsperren und -Reservoiren benutzen zu können, können die Mattenfelder in 2 und mehr "Etagen" (9 u. 10) angebracht werden. Außerdem wird es für diesen Gebrauchsfall zweckmäßig sein, die Flore durch Vernadelung mit einem auf einer oder beiden Seiten angebrachten Gittergewebe oder Preßflor oder Chemiefaserfilz so zu verdichten, daß auch Jungfische nicht hindurchdringen können (Fig. 3). Eine noch höhere Absicherung wird durch das Einnadeln einer hochporösen Kunstschaumstoffbahn erzielt. Die durchgenadelten Fasern oder Fäden der Matten bilden auf der Abseite einen Schlingenflor von hoher Schutzwirkung (Fig. 4). In den Floren können sich Mikroben und andere Kleinlebewesen von Fischen und Wasservögeln ungestört entwickeln, wobei die "Etagenflore" den Fischen das Eindringen verwehren. Die stark angereicherte Welt der Kleinlebewesen sorgt für eine intensivere Wasserreinigung, ohne daß diese Kleinlebewesen irgendwie durch die Flore behindert werden. Fiir Fische aber sind die Flore undurchdringliche Barrieren.To the same mats also for better biological cleaning in To be able to use fresh water dams and reservoirs, the mat fields in 2 or more "floors" (9 and 10). Besides, it will be for this one Use case be appropriate, the pile by needling with a on one or both sides attached mesh fabric or press pile or synthetic fiber felt so too condense so that even young fish cannot penetrate (Fig. 3). One more greater protection is achieved by needling in a highly porous synthetic foam sheet achieved. The needled fibers or threads of the mats form on the reverse side a loop pile of high protective effect (Fig. 4). In the floras can Microbes and other small organisms of fish and water birds develop undisturbed, whereby the "floor pile" prevents the fish from entering. The heavily fortified World of small organisms ensures more intensive water purification without this Small creatures are somehow hindered by the pile. But for fish there are the pile impenetrable barriers.

Der große Vorteil dieser "Mattenfelder" gegenüber den am Boden verankerten "künstlichen Seetangwiesen" besteht in dem viel geringeren Aufwand an Material und Verlegearbeit, in den von-der Tiefe unabiiängigen Planen uild in der Tatsache, daß die schwimmenden "Mattenfelder" fortgesetzt gereinigt und daher dauernd funktionstüchtig bleiben.The great advantage of these "mat fields" over those anchored to the ground "artificial seaweed meadows" consists in the much lower expenditure of material and Laying work, in the plans independent of the depth uild in the fact that the floating "mat fields" are continuously cleaned and therefore always functional stay.

Flore der genannten Art sind bereits bekannt geworden durch die GM 1 988 181 und GM 6 800 171 der Anmelderin zur Befestigung von Dämmen, Deichen, Böschungen, usw.Piles of the type mentioned have already become known through the GM 1 988 181 and GM 6 800 171 of the applicant for the fastening of dams, dykes, embankments, etc.

Nur ist hier Anwendung und äußere Formgebung dem neuen Einsatzzweck angepaßt. Auch hier sind die einzelnen gekräuselten Fäden außer einer intenisven Vernadelung durch seewasserbeständigen Kleber oder eingearbeitete Schmelzfäden fest miteinander verbunden.The only difference is that the application and external design are the new purpose customized. Here, too, are the individual crimped threads except an intensive needling with seawater-resistant adhesive or incorporated Fusion threads firmly connected to one another.
