Abstract
Description
Das Trockenlegen von Gebäuden und Flächen hat schon Tradition. Der Einsatz von Dränelementen, und zwar in den früheren Zeiten bestand aus Naturmaterial, und zwar aus Steinplatten mit denen man kleine Wasserabzugskanäle baute. Später wurden die Entwäs serungselemente aus grobkeramischen Dränrohren her gestellt. In jüngerer Zeit verwendet man vorwiegend PVC-Dränrohre mit Einlaufschlitzen.The draining of buildings and areas already has Tradition. The use of drainage elements, namely in the early days was made of natural material, and that from stone slabs with which small ones Drainage channels built. Later the drains Cleaning elements made of heavy clay drainage pipes posed. In recent times one uses predominantly PVC drainage pipes with inlet slots.
Für die Vertikaldränage kommen bitumengebundene Polystyrolsickerplatten, Bitumenwellplatten oder Noppenfolie zur Anwendung.Bitumen-bound come for the vertical drainage Polystyrene seepage sheets, corrugated bitumen sheets or Bubble film for use.
Der in Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die enormen Massen von Plastmüll, die täglich in den Haushaltungen, Gewerbebetrieben und Produktionsstätten als Abfall anfallen, nicht mehr in den Müllverbrennungsanlagen zu vernichten, wodurch bekanntlich eine Unmenge Schadstoffe frei gesetzt werden. Ebenfalls trägt die Entsorgung von Plastmüll auf den Abfalldeponien nicht zu einer sauberen und ästhetischen Umwelt bei und außerdem wachsen die Müllberge ständig weiter, so das die dazu benötigten Flächen schon jetzt nicht mehr ausreichen.The invention specified in claim 1 is Problem, the enormous masses of plastic waste, the daily in households, businesses and production facilities are not waste to destroy more in the waste incineration plants, which is known to release a multitude of pollutants be set. The disposal of Plastic waste does not become one at the landfill clean and aesthetic environment at and also the mountains of garbage keep growing, so that areas are no longer required for this suffice.
Ein weiteres,aber anderes Problem der in Anspruch 1 angegebenen Erfindung, wären die Wasserschäden die durch starke Bodenvernässungen an Gebäuden und sonstigen Bauwerken durch Sicker-, Schicht-, Stau und Grundwasser entstehen, könnte durch Einbau von Dränsickerelementen entgegengewirkt werden. Another but different problem of claim 1 specified invention, the water damage would be the due to heavy soil moisture on buildings and other structures due to seepage, stratification, traffic jams and groundwater could arise by installing Drainage elements are counteracted.
Dieses Problem wird nach Anspruch 1 gelöst indem man Plastmüll vorwärmt und einige Millimeter breit häckselt, so daß der Plastmüll längliche Streifen bzw. Fäden ergibt.This problem is solved according to claim 1 by Preheated plastic waste and a few millimeters wide chops, so that the plastic waste elongated strips or Threads results.
Das so aus Plastmüll hergestellte Material wird ge reinigt und danach im Heißzustand zu Dränsickermat ten geformt.The material so made of plastic waste is ge cleans and then in a hot state to drain drainage shaped.
Nach der Erkaltung der Dränsickermatte haben sich die Streifen bzw. die Fäden des zerkleinerten Plastmaterials derartig verfilzt und z. T. miteinander verschweißt so das daraus eine elastische und stabile Platte mit vielen Hohlräumen geworden ist. Die Hohlräume der Dränsickermatte sind die eigentlichen Dränorgane in denen sich die Nässe aus den Niederschlägen, Schnee schmelzungen, den wasserdurchlässigen Erdschichten und den Kapillarwirkungen ansammelt und unmittelbar den Dränsammler zuführt.After the drainage mat has cooled, the Strips or the threads of the shredded plastic material so matted and z. T. welded together like this the resulting an elastic and stable plate with many cavities. The cavities of the Drainage mat are the actual drainage organs in which the wetness from the rainfall, snow melting, the permeable layers of earth and accumulates the capillary effects and immediately the Feeder drains.
Mit der Erfindung wird nach Anspruch 1 erreicht, das durch umweltfreundliche und energiesparende Aufbereitung aus Plastmüll ein hochwertiges Material zurückgewonnen wird, das Ergebnis; die Müllberge werden nicht mehr so wachsen und in der Müllverbrennung tritt eine Reduktion ein.With the invention is achieved according to claim 1, the through environmentally friendly and energy-saving processing a high-quality material is recovered from plastic waste will, the result; the mountains of garbage are no longer like this grow and there is a reduction in waste incineration a.
Ein weiterer Gewinn: Durch den Einsatz bzw. Einbau von Dränsickermatten werden Bauwerke vor Durchnässung und vor Verfall bewahrt.Another benefit: By using or installing Drainage mats become structures before drenching and saved from decay.
Die vorteilhaften Einsatzmöglichkeiten der Erfindung sind in den Ansprüchen 1-3 angegeben.The advantageous possible uses of the invention are given in claims 1-3.
So ist nach Anspruch 1 der Einsatz von Dränsicker matten als vertikales Dränelement auf Kelleraußen wänden, an Stützwänden und sonstigen Baukörpern, also für alle erdberührenden Bauteile notwendig, denn das anstehende oder der zeitweise Wasserandrang aus dem Erdreich wird durch die Hohlräume/Dränorgane der Dränsickermatte aufgenommen und unmittelbar den Dranableitungsrohren bzw. Entwässerungssystem zuge führt.So is the use of drainage according to claim 1 mats as a vertical drainage element on the outside of the basement walls, on retaining walls and other structures, that is necessary for all components in contact with the earth, because that pending or the occasional water rush from the Soil is through the cavities / drainage organs of the Drainage mat added and immediately the Drainage pipes or drainage system supplied leads.
Nach Anspruch 2 ist der Einbau der Dränsickermatte als horizontale Flächendränage unter Wegen, Sport- u. Spielplätzen u.ä. besonders notwendig und vorteilhaft, denn die Sickerwasser bzw. die Oberflächenwasser aus den Niederschlägen werden unmittelbar von den Hohl räumen/Dränorganen der Dränsickermatte aufgenommen und dem Entwässerungssystem zugeleitet.According to claim 2, the installation of the drainage mat as a horizontal drainage under paths, sports and. Playgrounds etc. particularly necessary and advantageous, because the leachate or surface water Precipitation is directly from the hollow clearing / drainage organs of the drainage mat added and fed to the drainage system.
Die so dränierten Flächen werden vor Aufweichung geschützt und begehbar und bespielbar erhalten. Weiter kann bei Anlegen von Mülldeponien, Lager flächen u.ä. eine horizontale Flächendränage aus Dränsickermatten eingearbeitet werden.The areas drained in this way are before softening protected and accessible and playable. Furthermore, when creating landfills, storage surfaces and the like a horizontal drainage Drainage mats can be incorporated.
Es wird dadurch erreicht, daß die Niederschläge aus Regen und Schnee, die sich in den Müllhalden bzw. Lagerflächen ansammeln aufgefangen und kontrollier bar abgeleitet werden, ohne daß sie in das Erdreich eindringen und das Grundwasser beeinträchtigen können.It is achieved in that the rainfall Rain and snow that are in the rubbish dumps or Collect and control storage areas bar can be derived without being in the ground penetrate and affect the groundwater can.
Darüber hinaus kann nach Anspruch 3 die Dränsicker matte auch als Schallschluckelement in Form von Ver kleidung der Lärmschutzwände der Autobahnen, Eisen bahnen und dgl. Verwendung finden.In addition, the drainage can according to claim 3 matte also as a sound absorbing element in the form of Ver clothing of the noise barriers of the highways, iron webs and the like. Find use.
Die Dränsickermatte übernimmt die Aufgabe einer Lärmdämmung d. h. in den Hohlräumen der Matte ver fängt sich der Lärm bzw. die Motorengeräusche und werden dort zum abklingen gebracht, so daß der Lärm nicht als Echo zurückprallen kann.The drainage mat does the job of one Noise reduction d. H. ver in the cavities of the mat catches the noise or the engine noise and are brought to decay there so that the noise does not can bounce back as an echo.
