Abstract
Description
Die Erfindung betrifft eine Deponie-Basisabdichtung aus Kunststoff.The invention relates to a landfill base seal Plastic.
Bei Deponie-Basisabdichtungen werden erhebliche Anforderungen an die Dichtwirkung gestellt. Diese Anforderung gilt nicht nur für die Abdichtung gegenüber Wasser, sondern auch gegenüber anderen Stoffen, z. B. Kohlenwasserstoffen. Seit langem wird Polyethylen im Deponie-Bereich als derjenige Stoff angesehen, der gegenüber anderen Kunststoffen eine deutlich größere Dichtwirkung besitzt. Dabei ist man sich bewußt, daß auch Polyethylen nur eine relative Abdichtung gewährleistet. Einige Stoffe durchdringen in gewissen Raten auch Polyethylen. Der Erfindung liegt daher die Aufgabe zugrunde, Deponie-Basisabdichtungen weiter zu verbessern.With landfill basic seals there are considerable requirements the sealing effect. This requirement does not only apply to sealing against water, but also against others Fabrics, e.g. B. hydrocarbons. Polyethylene has been used for a long time considered in the landfill area as the substance facing other plastics have a significantly greater sealing effect. It is well known that polyethylene is only a relative one Sealing guaranteed. Some substances penetrate in certain Also advise polyethylene. The invention is therefore the object basis to further improve landfill base seals.
Nach der Erfindung wird das mit Hilfe einer Polyester-Schicht erreicht. Die Polyester-Schicht hat vorzugsweise eine Dicke bis 0,1 mm.According to the invention, this is done with the help of a polyester layer reached. The polyester layer preferably has a thickness of up to 0.1 mm.
Der Polyester kann aufgesprüht werden. Nach der Fertigstellung der gesamten Kunststoff-Basisabdichtung kann mit einem ab schließenden Aufsprühen eine vollständig geschlossene Ab dichtungsschicht erstellt werden.The polyester can be sprayed on. After completion the entire plastic base seal can be covered with one closing spraying a completely closed ab sealing layer can be created.
Wahlweise kann die Polyester-Schicht auch eine Zwischenschicht der Kunststoffbahnen bilden, die üblicherweise zu der Basisab dichtung zusammengesetzt werden. Die Einbettung der Polyester- Schicht hat den Vorteil der Verschweißbarkeit bei verschweißbaren Deckschichten. Für die Abdichtung gegen die extrem schädlichen Sickerwasserbestandteile der Deponie ist es günstig, wenn große Überlappungsränder an den Abdichtungsbahnen gewählt werden und die verschweißte Deckschicht zwischen den Abdichtungsbahnen möglichst dünn ist. Vorzugsweise dringt die Schicht bis 0,1 mm.Optionally, the polyester layer can also be an intermediate layer of the plastic sheets that usually form the base seal are assembled. Embedding the polyester Layer has the advantage of being weldable with weldable Top layers. For sealing against the extremely harmful Leachate components of the landfill, it is favorable if large Overlap edges can be chosen on the waterproofing membrane and the welded cover layer between the waterproofing membranes is as thin as possible. The layer preferably penetrates to 0.1 mm.
In der Zeichnung sind verschiedene Ausführungsbeispiele der Erfindung dargestellt.In the drawing, various embodiments of the Invention shown.
Fig. 1 zeigt den Ausschnitt einer Deponie-Basisabdichtung mit zwei Abdichtungsbahnen 1 und 2 aus Kunststoff, die mit einer Polyester-Schicht 3 überdeckt worden sind. Die Polyester- Schicht 3 ist nach Verschweißen aller Abdichtungsbahnen aufge sprüht worden. Anstelle des Aufsprühens kommen auch andere Ver fahrensweisen zum Auftragen der Schicht in Betracht. Fig. 1 shows the detail of a landfill base seal with two sealing sheets 1 and 2 made of plastic, which have been covered with a polyester layer 3 . The polyester layer 3 has been sprayed on after welding all the sealing sheets. Instead of spraying, other methods of applying the layer can also be considered.
Nach Fig. 2 sind Abdichtungsbahnen 10, 11 und 12 aus Kunststoff vorgesehen. Die Abdichtungsbahnen besitzen eine Zwischen schicht 13 bzw. 14 aus Polyester sowie eine Deckschicht 15, 16 bzw. 17 aus verschweißbarem Kunststoff. Nach Fig. 2 folgt das Verschweißen jeweils nur an den Deckschichten. Das bedingt, daß die Abdichtungsbahnen verschieden ausgelegt werden, die einen mit der Deckschicht nach oben, die anderen darüber mit der Deck schicht nach unten.According to FIG. 2, sealing strips 10, 11 and 12 are provided from plastic. The sealing sheets have an intermediate layer 13 or 14 made of polyester and a cover layer 15 , 16 or 17 made of weldable plastic. According to Fig. 2, the welding follows only on the cover layers. This means that the waterproofing membranes are designed differently, some with the top layer up, the others with the top layer down.
Im Ausführungsbeispiel sind die Polyester-Schichten 0,05 mm dick. Die im Ausführungsbeispiel nach Fig. 2 vorgesehenen Deck schichten besitzen die gleiche Dicke.In the exemplary embodiment, the polyester layers are 0.05 mm thick. The cover layers provided in the embodiment according to FIG. 2 have the same thickness.
