Abstract

Covering structure to block gas passing through, an intermediate layer (6) of a material which swells and retains water is inserted between layers (5, 7) of mineralised and cement-bonded waste from the textile and leather industries, which are not brittle and subject to cracking. Pref. the intermediate layer (6), between the upper and lower layers (5, 7), is a water-retaining mineral powder mass contained and fixed within stretch textile materials as a textile structure. Or the mineral powder for the intermediate layer (6) can be contained within two layers of non-woven materials, where the carrier layer rests on the bottom layer (7) of the cover, from a mineralised and cement-bonded waste. The intermediate layer (6) can also be a sealing matting with a covering layer (5) from pre-fabricated plates of chopped textiles and cement concrete, or laid concrete as with the bottom layer (7). For covering heaps which emit radon, an additional plastics sealing layer (9) is between the bottom layer (7) of laid concrete with chopped textiles and cement, and the water-retaining intermediate layer (6). USE/ADVANTAGE - The covering is used for erection over rubbish dumps, slag heaps, filled mud holes and swamp land and other applications where large areas emit gas. The material is not damaged by anticipated stresses, and also resists changing conditions.

Description

Die Erfindung betrifft ein Verfahren, das anwendbar ist für die Herstellung von gasdurchtrittshemmenden Konstruktions­ schichten zur Abdeckung großflächiger, Gase emittierender Areale, wie z. B. Mülldeponien, Bergbauhalden, verfüllte Sumpflöcher und Moore. Gleichzeitig bietet das Verfahren die Möglichkeit, Abfälle der Textil- und Lederindustrie in Schnitzelform einer Verwertung zuzuführen und dadurch Deponien zu entlasten, wobei eine massenhafte Entsorgung dieser Industriezweige gesichert werden kann.The invention relates to a method that is applicable for the production of gas penetration-resistant construction layers to cover large, gas-emitting Areas such as B. landfills, mining dumps, backfilled Swampholes and bogs. At the same time, the process offers the opportunity to waste the textile and leather industry in Recycle the schnitzel shape and thereby Relieve landfills, with mass disposal of these industries can be secured.

Die bekannten technischen Lösungen nutzen in der Regel Folien aus verschiedenen Materialien, wie z. B. Polyäthy­ len, Polypropylen, Polyester, Polyamid, Polyvinylchlorid o. ä. Hochpolymere zur Abdeckung von gasemittierenden Flä­ chen, wie z. B. Radon abgebenden Uranbergbauhalden. Die Folien werden noch mit einer Erdschicht bedeckt.The known technical solutions are usually used Films made of different materials, such as B. Polyethy len, polypropylene, polyester, polyamide, polyvinyl chloride High polymers to cover gas-emitting surfaces chen, such as B. Radon-emitting uranium mines. The Foils are still covered with a layer of earth.

Der Erfindung liegt die Aufgabe zugrunde, eine gasdurch­ trittshemmende Abdeckung herzustellen, die durch mögliche Belastungen nicht zerstört wird und ebenso wechselnden Beanspruchungen standhält.The invention has for its object a gas through manufacture anti-slip cover by possible Loads are not destroyed and just as changing Withstands stress.

Eine erfindungsgemäße Lösung dieser Aufgabe ist im Patent­ anspruch 1 angegeben. Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. An inventive solution to this problem is in the patent Claim 1 specified. Developments of the invention are characterized in the subclaims.  

Der prinzipielle Lösungsansatz besteht darin, daß die gasdurchtrittshemmende Schicht zwischen eine nichtspröd­ brüchige Ober- und Unterschicht eingebracht wird. Zur Herstellung solcher nichtsprödbrüchiger Schichten eignen sich besonders mineralisierte und zementgebundene Abfall­ schnitzel, die ein gleichartiges elastisches Verhalten wie die zu schützende Zwischenschicht aufweisen.The basic approach is that the gas barrier layer between a non-brittle brittle top and bottom layers are introduced. For Production of such non-brittle layers are suitable particularly mineralized and cement-bound waste schnitzel that have a similar elastic behavior like have the intermediate layer to be protected.

Diese gasdurchtrittshemmende Zwischenschicht besteht vorteilhaft aus einer wasserspeichernden und quellenden mineralischen Pulvermasse, die zwischen zwei elastischen Textilbahnen eingebracht und dort textil fixiert ist.This gas penetration-resistant intermediate layer is made advantageous from a water-storing and swelling mineral powder mass between two elastic Textile webs introduced and textile fixed there.

Der Effekt der Gasdurchtrittshemmung wird dadurch erzielt, daß sich in der wasserspeichernden mineralischen Pulver­ masse eine ausreichend dicke Wasserschicht ausbildet, die einen Gasdurchtritt unterbindet.The effect of gas penetration inhibition is achieved that is in the water-storing mineral powder mass forms a sufficiently thick layer of water that prevents the passage of gas.

Die weitere Ausbildung der Erfindung kann den Patentan­ sprüchen entnommen werden.The further development of the invention can the patent sayings are taken.

Die mit der Erfindung erzielten Vorteile bestehen insbe­ sondere darin, daß die nichtsprödbrüchigen flexiblen Kon­ struktionsschichten durch mögliche Belastungen nicht zer­ stört werden und wechselnden Beanspruchungen standhalten sowie durch die wasserspeichernde Wirkung des zwischen Vliesbahnen eingelagerten pulverförmigen quellfähigen Minerals eine sichere gasdurchtrittshemmende Schicht ent­ steht.The advantages achieved with the invention are in particular special in that the non-brittle flexible Kon structural layers are not destroyed by possible loads be disturbed and withstand changing loads as well as the water-storing effect of the between Nonwoven webs of powdered swellable material Minerals ent a safe gas barrier layer stands.

Die erfindungsgemäß angestrebten nichtsprödbrüchigen Ei­ genschaften der Konstruktionsschichten gegenüber herkömm­ lichem Zementbeton werden dadurch erreicht, daß minerali­ sierte Abfallschnitzel aus Textil und Leder statt der Sand-Kies-Zuschlagstoffe eingesetzt werden, wodurch sich gleichzeitig der Zementbedarf reduziert. Die Verwendung von Abfällen der Textil- und Lederindustrie führt eben­ falls zur Entlastung von sonst benötigten Sonderdeponien und zur Vermeidung von umweltbelastenden Spätfolgen.The non-brittle egg desired according to the invention Properties of the construction layers compared to conventional Lich cement concrete are achieved in that minerali garbage chips made of textile and leather instead of  Sand-gravel aggregates are used, which results in at the same time the cement requirement is reduced. The usage of waste from the textile and leather industry just leads if to relieve special landfills otherwise required and to avoid environmentally damaging late effects.

Ein wesentlicher Vorteil besteht auch in der die radioak­ tive Strahlung reduzierenden Wirkung der eingelagerten Wasserschicht im gequollenen Mineralpulver sowie in der Vermeidung der Emission von radioaktiven Gasen überhaupt.A major advantage is that the radioak tive radiation reducing effect of the stored Layer of water in the swollen mineral powder as well as in the Avoiding the emission of radioactive gases at all.

Einen weiteren Vorteil bringt die Verwendung mineralisier­ ter Abfälle durch die Erhöhung der Nutzungsdauer der hoch­ polymeren Grundmaterialien infolge des Vorbehandlungsef­ fektes. Dadurch wird einem chemischen Abbaueffekt entge­ gengewirkt.Another advantage is the use of mineralized ter waste by increasing the useful life of the high polymeric base materials due to the pretreatment fect. This counteracts a chemical degradation effect counteracted.
