Abstract
Description
Gegenstand der Grundanmeldung sind Matten aus synthetischen Fasern mit wasser- und säurefester Bindung zur Befestigung von Bahn-,- Straßen- und ähnlichen Dämmen, Deichen, Böschungen und zum Belegen von Sohlen von Schiffahrtswegen, von Sportplätzen und dergleichen.The basic application relates to mats made from synthetic fibers With water- and acid-proof binding for fastening rail, road and similar Dams, dykes, embankments and for covering the floors of shipping routes, from Sports fields and the like.
Nach Anspruch 2 sind diese endlosen Matten durch aufkaschiertes Gitter- ! gewebe oder Fäden aus Kunststoff verstärkt.According to claim 2, these endless mats are laminated by lattice ! Reinforced fabric or threads made of plastic.
In der Praxis hat es sich nun gezeigt, daß diese Verstärkung nur bis zu einer gewissen Länge empfehlenawert ist, die aber nicht genügt, wenn die Matten beim Verlegen auf größere Distanz auf Zug beanc sprucht werden.In practice it has now been shown that this gain is only up to a certain length is recommended, but this is not sufficient if the mats when laying at a greater distance, they are subject to tension.
Ferner hat sich gezeigt, daß beim Befestigen von Uferdämmen oder Kanalsohlen der Treibsand wesentlich besser festgehalten wird, wenn die Matten unterteilt sind in kissenartige kleinere Felder.It has also been shown that when fastening embankments or canal bottoms the quicksand is held much better if the mats are divided in pillow-like smaller fields.
Beim gleichen Verwendungszweck hat sich außerdem als Mangel hwrausgestellt, daß das spez. Gewicht der Matten zu leicht war, um eine sichere Verlegung zu gewährleisten. Die Wasserbewegung durch die Schiffsschrauben treibt die Matten aus ihrer Lage.For the same purpose, it also turned out to be a defect that the spec. The weight of the mats was too light to ensure safe installation. The movement of the water through the propellers drives the mats out of position.
Um diese Elängel abzustellen wird erfindungsgemäß vorgeschlagen1 statt der Verstärkung durch Gittergewebe oder Kunststoff-Fäden die Matten unmittelbar vor der Abbindung des Bindemittels durch schmale Preßwalzen zu leiten, so daß sie streifenweise verdichtet werden, wodurch eine erhebliche Zunahme der Zugfestigkeit erreicht wird. In Fig. 1 sind die Kanten lt und 12 und die Innenfläche durch derartige Verdichtungen 13 und 14 verstärkt.In order to remedy this problem, the invention proposes 1 instead reinforcement by means of mesh or plastic threads, the mats directly before the binding agent sets through narrow press rollers so that they be compacted in strips, resulting in a significant increase in tensile strength is achieved. In Fig. 1, the edges 1 and 12 and the inner surface are through such Compressions 13 and 14 reinforced.
In Figv 2 wird dargestellt, wie die ganze Fläche der Matte durch kissenartige Abpressungen aufgeteilt ist in kleine Felder 21, deren Umrantungen 22 Verdichtungen darstellen, wodurch der Treibsand festgehalten wird. Außerdem wirken die Einbuchtungen über den Verdichtungen der Sandbewegung entgegen.In Figv 2 it is shown how the entire surface of the mat by pillow-like Pressings is divided into small fields 21, the boundaries of which are 22 compaction represent, whereby the quicksand is held. The indentations also work against the compaction of the sand movement.
Um das spezifische Gewicht der Runststoffmattell über l.o zu erhöhen, wird vorgeschlagen, dem Bindemittel neutrale Füllstoffe beizugeben wie beispielsweise Schwerspat oder dergleichen.In order to increase the specific weight of the plastic mat over l.o, it is proposed to add neutral fillers to the binder, such as Barite or the like.
