Abstract
Description
Die bisher bekannten Dichtungssysteme bestehen entweder aus Tonmineralgemischen, Fo lien, Bitumendecken, Bentonitmatten oder einer Kombination dieser Elemente. Darüber hin aus wird in der Patentschrift EP 0 125 680 B1 ein Verfahren zur Abdichtung einer unter der Bodenoberfläche liegenden Bodenschicht aus Sand oder Kiessand mit Klärschlamm be schrieben. Diese Verfahren haben teilweise erhebliche Mängel, die besonders während der Verarbeitungsphase oder sind sehr kostenintensiv, da es sich bei dem überwiegenden Teil der Komponente um wertvolle Rohstoffe handelt. Das nachstehend beschriebene Verfahren ermöglicht eine einfache und sichere Verarbeitung, was zu einer deutlichen Qualitätsverbes serung führt. Darüber hinaus ist es erheblich kostengünstiger, da es sich bei dem überwie genden Teil der Komponenten um Rest- bzw. Abfallstoffe handelt, die durch dieses Verfah ren einer sinnvollen stofflichen Verwerdung zugeführt werden.The sealing systems known to date either consist of clay mineral mixtures, Fo lien, bitumen ceilings, bentonite mats or a combination of these elements. Beyond that From the patent specification EP 0 125 680 B1 a method for sealing an under the Bottom layer of sand or gravel sand with sewage sludge wrote. Some of these procedures have significant shortcomings, particularly during the Processing phase or are very costly since it is the predominant part the component is valuable raw materials. The procedure described below enables simple and safe processing, resulting in a clear quality change leads. In addition, it is considerably cheaper, since it was overwhelming part of the components are residues or wastes that are caused by this procedure can be fed into a sensible material use.
In den Schriften DE 28 03 251 C3, EP 0 803 560 A1, WO 00/44853, DE 198 44 654 A1 und DE 198 59 796 A1 werden Verfahren zur Abdichtung von Gesteinen beschrieben.In the documents DE 28 03 251 C3, EP 0 803 560 A1, WO 00/44853, DE 198 44 654 A1 and DE 198 59 796 A1 describes methods for sealing rocks.
Die Verwendung von Klärschlamm in Bodensubstraten wird in DE 41 09 759 C1, EP 0 536 716 A1, DE 42 37 503 A1, DT 20 33 508 C3 beschrieben.The use of sewage sludge in soil substrates is described in DE 41 09 759 C1, EP 0 536 716 A1, DE 42 37 503 A1, DT 20 33 508 C3.
Bei dem hier beschriebenen Verfahren handelt es sich um ein organisch-mineralisches Dich tungssystem, das aus natürlichen gemischtkörnigen oder feinkörnigen Böden besteht, die mit Klärschlamm, Glasschleifschlamm oder Keramikschlamm, bentonithaltigen Gießereialtsan den sowie Prozentbruchteilen von Wasserglas vergütet werden.The process described here is an organic-mineral dich system consisting of natural mixed-grained or fine-grained soils that with Sewage sludge, glass grinding sludge or ceramic sludge, bentonite-containing foundry the and fractional percentages of water glass.
Das Verfahren ermöglicht die Verwendung gemischtkörniger oder feinkörniger natürlicher Böden, die für den Einsatz im Dichtungsbau nicht ausreichend geringe Durchlässigkeiten aufweisen. Dazu werden Dichtungssysteme hergestellt, die aus 30-75% natürlichen ge mischt- oder feinkörnigen Böden, 15-40% Klärschlamm aus kommunalen oder industriel len Abwasserreinigungsanlagen und/oder Glasschleifschlamm oder Keramikschlamm aus der industriellen Glas- und Keramikherstellung, 10-30% bentonithaltigen Gießereialtsan den und max. 1,5% Wasserglas bestehen.The process enables the use of mixed-grain or fine-grain natural ones Floors that are not sufficiently low permeability for use in sealing construction exhibit. For this purpose, sealing systems are made that are made of 30-75% natural ge mixed or fine-grained soils, 15-40% sewage sludge from municipal or industrial len wastewater treatment plants and / or glass grinding sludge or ceramic sludge industrial glass and ceramic production, 10-30% bentonite-containing foundry den and max. 1.5% water glass exist.
Für die Komponente gemischt- oder feinkörnige Böden werden natürliche Böden verwendet, die aufgrund ihrer Zusammensetzung bzw. ihrer Inhomogenität für den Einsatz in Dichtungs elementen normalerweise ungeeignet sind. Diese natürlichen Böden können auch durch die nicht verwertbaren Feinanteile, die bei der Herstellung von Recyclingbaustoffen entstehen, ersetzt werden.Natural soils are used for the component mixed or fine-grained soils, due to their composition or their inhomogeneity for use in sealing elements are usually unsuitable. These natural soils can also be removed through the non-usable fines that arise during the production of recycled building materials, be replaced.
Die Komponente Klärschlamm und die darin befindliche organische Substanz liegt feinverteilt in den Gemischen vor und verhindert bei Wassergehaltsänderungen die beim Dichtungsbau gefürchteten Rissbildungen, da in den organischen meist faserigen Bestandteile adsorptiv gebundenes Wasser langsam abgegeben und so als Puffer der Bildung von Schrumpfrissen entgegenwirkt. Der Glasschleifschlamm oder Keramikschlamm kann substituierend für den Klärschlamm eingesetzt werden, da er ebenso als wasserregulierender Puffer wirkt. Die ebenfalls als Zuschlagstoff verwendeten bentonithaltigen Gießereialtsande dienen als Stützmasse. Der darin enthaltene Bentonitanteil senkt die Durchlässigkeit des Bodengemi sches.The sewage sludge component and the organic substance contained therein are finely divided in the mixtures and prevents changes in the water content during sealing construction dreaded cracks, because in the organic mostly fibrous components adsorptive bound water slowly released and thus as a buffer for the formation of shrinkage cracks counteracts. The glass grinding sludge or ceramic sludge can be substituted for the Sewage sludge can be used because it also acts as a water regulating buffer. The bentonite-containing foundry sands also used as an additive serve as Supporting mass. The bentonite content contained therein lowers the permeability of the soil mixture MOORISH.
Außerdem wird zur Verstärkung der abdichtenden Wirkung sowie zur Stabilisierung der or ganischen Substanz Wasserglas in Prozentbruchteilen bis max. 1,5% Massenanteil zuge geben. Die Vermischung mit dem Bodenwasser führt zu einer Gelbildung, die auch die Durchlässigkeit herabsetzt. Gleichzeitig bewirkt diese Komponente die Einstellung der Akti vität der im Klärschlamm enthaltenen organischen Substanz, die zu unerwünschten Neben erscheinungen führen würde, wie Gasbildung und Volumenverminderungen durch die Zer setzung.In addition, to strengthen the sealing effect and to stabilize the or ganic substance water glass in fractions of a percentage up to max. 1.5% mass fraction added give. Mixing with the soil water leads to gel formation, which also Permeability reduced. At the same time, this component effects the setting of the shares The organic matter contained in the sewage sludge leads to undesirable additions phenomena would lead, such as gas formation and volume reductions through the Zer setting.
Die Herstellung des Dichtungssystems erfolgt entweder durch das Ausstreuen der Einzel komponenten auf einer Verarbeitungsfläche oder der abzudichtenden Fläche und anschlie ßendem Vermischen mit Bodenfräsen oder durch die Herstellung in einer Zwangsmischan lage. Nach dem Ausbreiten auf der abzudichtenden Fläche wird die dichtende Schicht ver dichtet, wobei beim Aufbringen in mehreren Lagen auf eine Verzahnung der Lagen zu ach ten ist. Anschließend werden Schutz- u. Vegetationsschichten aufgebracht.The sealing system is produced either by spreading the individual parts components on a processing surface or the surface to be sealed and then mixing with tillers or by manufacturing in a compulsory mixer location. After spreading on the surface to be sealed, the sealing layer is ver seals, whereby when applying in several layers to a serration of the layers is. Then protection u. Vegetation layers applied.
Das Verfahren hat gegenüber den Verfahren, die Dichtungen aus mineralischen Kompo nenten nach dem Stand der Technik entsprechen, den Vorteil, daß auch unter geringer Überdeckung durch Schutzschichten oder Vegetationsschichten sowie bei der Verarbeitung die Gefahr der Rissbildung durch Austrocknung deutlich verringert wird. Es können natürli che Böden verwendet werden, die nicht ausreichend geringe Durchlässigkeiten aufweisen, Klärschlamm und Gießereialtsande werden einer sinnvollen Verwertung zugeführt und es werden geringe Durchlässigkeiten, gekennzeichnet durch hohe kf-Werte schon bei geringer Verdichtung erreicht. Zudem ist das beschriebene Verfahren gegenüber anderen beschrie benen Verfahren kostengünstiger.The method has the advantage over the methods, the seals made of mineral components according to the prior art, that even with little coverage by protective layers or vegetation layers and during processing, the risk of cracking due to drying out is significantly reduced. Natural soils that do not have sufficiently low permeability can be used, sewage sludge and foundry sands are recycled in a sensible manner and low permeability, characterized by high k f values, is achieved even with low compaction. In addition, the method described is less expensive than other methods described.
