Abstract
Description
Die Erfindung betrifft ein Drän-Entwässerungselement für Abfalldeponien und sonstige Verwendung im Erd- Grund- und Wasserbau.The invention relates to a drainage element for landfills and other uses in earthworks, foundation engineering and hydraulic engineering.
Der Wasserhaushalt einer Abfalldeponie spielt für die Sicherheit gegen Kontamination des Untergrundes eine entscheidende Rolle, denn Wasser ist das wichtigste Transportmedium für Schadstoffe. Solange die Deponie noch nicht mit einer wirksamen Oberflächenabdeckung versehen ist, durchsickert ein großer Teil der Niederschläge den Deponiekörper. Auf der Deponieabdichtung wird herkömmlich eine Kiesschicht aufgebracht, die anfallendes Sickerwasser filtert, sammelt und im freien Gefälle an Entwässerungsrohre ableitet. Um eine stabile Filterung zu gewährleisten, sowie einen schnellen Wasserabfluß zu erreichen, werden Kiesschichten bis zu 0.5 m Höhe und einer Korngröße zwischen 16-32 mm eingebracht. Die Einbringung der Kiesschicht in konstanter Stärke auf der Deponiesohle, sowie an den Böschungen erfordert einen erheblichen baulichen Aufwand. Für den Einsatzzweck in Deponien eignen sich nach behördlichen Vorgaben nur Kiese mit geringem Kalkanteil, da die Sickerwassereinwirkung zur Zersetzung des kalkhaltigen Kieses führt, was eine Lehmausbildung ermöglicht. Dies kann in einer Zusetzung der Kiesschicht resultieren, so daß sich das Wasser in den Müll zurückstaut und die Standsicherheit der Deponie gefährdet. Kalkarmes Kiesmaterial gibt es nur an wenigen Standorten und der damit verbundene Transport in den erforderlichen Mengen ist ein erheblicher Kostenfaktor.The water balance of a landfill plays against security Contamination of the subsurface plays a crucial role because water is the most important transport medium for pollutants. As long as the landfill is still is not provided with an effective surface covering, oozes a large part of the precipitation the landfill body. On the Landfill sealing is conventionally applied to a layer of gravel Leachate accumulates, collects, and collects in free slopes Drainage pipes. To ensure stable filtering, as well as to achieve a rapid water drainage, gravel layers up 0.5 m high and a grain size between 16-32 mm. The Placing the gravel layer in constant thickness on the bottom of the landfill, as well as on the embankments requires considerable construction effort. For the application in landfills are only suitable according to official requirements Gravel with a low lime content, since the influence of the leachate Decomposition of the calcareous gravel results in clay formation enables. This can result in an addition of the gravel layer, so that the water backs up in the garbage and the stability of the Landfill at risk. There are only a few limestone gravel materials Locations and the associated transport in the required quantities is a significant cost factor.
Der Erfindung liegt die Aufgabe zugrunde, ein Drän-Entwässerungselement für Abfalldeponien und sonstige Verwendung im Erd- Grund- und Wasserbau zu schaffen, das den herkömmlichen Filterkies ersetzt, eine erhebliche Einsparung an wertvollen Kiesressourcen schafft und einen einfacheren Einbau ermöglicht.The invention has for its object a drainage element for landfills and other uses in earthworks, foundation engineering and hydraulic engineering create, which replaces the conventional filter gravel, a considerable Saves valuable gravel resources and makes it easier Installation allows.
Diese Aufgabe wird durch ein Drän-Entwässerungselement der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1.This task is accomplished by a drainage element at the beginning mentioned genus solved according to the invention by the features of characterizing part of claim 1.
Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are in the subclaims specified.
Bei dem erfindungsgemäßen Drän-Entwässerungselement handelt es sich um einen Hohlkörper, mit vertikalen Stützelementen zur statischen Stabilität gegenüber der aufgebrachten Lasten.The drainage element according to the invention is a hollow body, with vertical support elements for static stability towards the applied loads.
Durch Verbindung der Drän-Entwässerungselemente entsteht aufgrund von Abflußöffnungen an den Außenseiten eine flächig ausgebildete Entwässerungsschicht, welche auf die im Gefälle liegende Deponieabdichtungsschicht ausgelegt wird. Das aus dem Deponiekörper anfallende Sickerwasser fließt durch Öffnungen an der Oberseite des Drän- Entwässerungselements. Die Öffnungen sind so gewählt, daß der Beiwert für die Durchlässigkeit von Filterkies erreicht wird.By connecting the drainage elements, due to Drainage openings on the outside of a flat Drainage layer, which is on the slope Landfill sealing layer is designed. That from the landfill body leachate is flowing through openings on the top of the drainage Drainage element. The openings are chosen so that the coefficient for the permeability of filter gravel is achieved.
Vorzugsweise wird ein Kunststoff verwendet, der chemisch beständig gegen das im Deponiekörper anfallende Sickerwasser ist, so daß eine hohe Lebensdauer gewährleistet wird. Bevorzugt wird ein umweltverträglicher Recycling-Kunststoff verwendet.A plastic that is chemically resistant to is preferably used the leachate accumulating in the landfill is so high Life is guaranteed. An environmentally friendly is preferred Recycled plastic used.
Im Folgenden wird die Erfindung anhand von einem in den Zeichnungen dargestellten Ausführungsbeispiel näher erläutert.In the following the invention is based on one in the drawings illustrated embodiment explained in more detail.

Das erfindungsgemäße Drän-Entwässerungselement besitzt gemäß Fig. 1 einen Unterboden 1, auf dem die vertikal stehenden Elementaußenseiten 2 mit Aussparungen 3 für den Wassertransport aufgebaut sind. Nach oben ist das Element durch eine Deckfläche 4 mit Öffnungen 5 für den Sickerwassereinlaß abgeschlossen. Zum Zusammenfügen der Elemente sind die Außenflächen mit Steckprofilen 6 versehen. Durch die Steckprofile 6 des Drän- Entwässerungselements ist ein Einbau der Entwässerungsschicht einfach und schnell möglich.According to FIG. 1, the drainage element according to the invention has a sub-floor 1 on which the vertically standing outer sides of the elements 2 with recesses 3 for water transport are constructed. The element is closed at the top by a cover surface 4 with openings 5 for the leachate inlet. To assemble the elements, the outer surfaces are provided with plug profiles 6 . The plug-in profiles 6 of the drainage element enable the drainage layer to be installed easily and quickly.
