Description
Verfahren und Abdichtung und Verfestigung von geologischen Formationen Zusatz zum Patent 1129 894 Das Patent 1129 894 betrifft ein Verfahren zur Abdichtung und Verfestigung von geologischen Formationen gegen Wasser oder Gas, dadurch gekennzeichnet, daß die ein vernetztes Produkt mit der Gruppe bildenden Reaktionskomponenten, nämlich ein Di-oder Polyisocyanat, und eine mindestens drei reaktionsfähige OH-Gruppen aufweisende organische Verbindung in Mischung miteinander in einem flüssigen Träger unter Druck in die abzudichtende oder zu verfestigende Formation eingepreßt werden.Method and sealing and consolidation of geological formations Addendum to patent 1129 894 The patent 1129 894 relates to a method for sealing and consolidating geological formations against water or gas, characterized in that a crosslinked product with the group forming reaction components, namely a di- or polyisocyanate, and an organic compound containing at least three reactive OH groups, mixed with one another in a liquid carrier, are pressed under pressure into the formation to be sealed or solidified.
Diese Abdichtungen haben sich in der Praxis hervorragend bewährt, besonders bei der Abdichtung von feinen Spalten, feinen, schwer durchlässigen Sanden u. dgl. Jedoch sind dem Mittel in der Praxis gewisse Grenzen gesetzt, wenn große Abdichtungen im diluvialen Gebirge und in Moränen durchgeführt werden sollen. Diese Formationen haben ein Porenvolumen von 20 bis 401/o, meistens verbunden mit einer starken Grundwasserströmung. Alle bekannten Mittel, wie Zementdispersionen, Tonschlämmen, Natriumsilikat, führen oft zum Versagen, da sich diese Stoffe mit dem fließenden Grundwasser vermischen und aus dem Dichtungsbereich herausgetragen werden.These seals have proven to be excellent in practice, especially when sealing fine crevices, fine, poorly permeable sands and the like. However, in practice there are certain limits to the means, if large ones Seals should be carried out in the diluvial mountains and in moraines. These Formations have a pore volume of 20 to 401 / o, mostly associated with one strong groundwater flow. All known agents, such as cement dispersions, clay slurries, Sodium silicate, often lead to failure, as these substances mix with the flowing Mix groundwater and be carried out of the sealing area.
Dieser Mangel wird durch die weitere Ausbildung der Erfindung des Hauptpatents beseitigt. Diese Weiterbildung besteht darin, daß zu der in die Formation einzupressenden Mischung des Hauptpatents noch 10 bis 70 Teile Flugasche zugesetzt werden.This deficiency is increased by the further development of the invention Main patent eliminated. This development consists in the fact that in the formation The mixture of the main patent to be pressed in was also added 10 to 70 parts of fly ash will.
Am besten eignet sich Flugasche aus Braunkohlekraftwerken, welche sehr feinteilig ist (1 bis 8 #t) und sich oleophil verhält, so daß ein gutes Einarbeiten möglich ist. Die Flugasche bringt ferner die Mischung zum Quellen, so daß eine Volumenvergrößerung bis zu 30 0/ o eintreten. kann. Ein weiterer Vorteil besteht darin, daß selbst dann, wenn durch die Feststoffanteile ein Filterkuchen gebildet wird, sich das flüssige Produkt verfestigt und nicht, wie beim Zement od. dgl., sich mit dem anstehenden Wasser vermischt und dann weggeschwemmt wird.Fly ash from lignite power plants, which is very finely divided (1 to 8 #t) and is oleophilic, so that it can be incorporated well is possible. The fly ash also causes the mixture to swell, so that an increase in volume up to 30%. can. Another advantage is that even then if a filter cake is formed by the solid fractions, the liquid Solidified product and not, as with cement or the like., With the upcoming Water is mixed and then washed away.
Der einzupressenden Mischung können auch noch kationogene Stoffe, wie quaternäre Ammoniumsalze oder stark basische, hochmolekulare Amine, Zugesetzt werden. Hierdurch wird Schaumbildung mit geschlossenem Blasensystem bewirkt.The mixture to be injected can also contain cationogenic substances, like quaternary ammonium salts or strongly basic, high molecular weight amines, added will. This causes foam formation with a closed bubble system.
Als Beispiel einer solchen Mischung können genannt werden: 1. 150 Teile Rizinusöl, 150 Teile Tallöl, 30 Teile 2,4-Toluidenisocyanat, 700 Teile Flugasche. Eine solche Mischung ergibt einen hochelastischen Körper mit einer Shorehärte zwischen 30 und 40.As an example of such a mixture can be mentioned: 1. 150 Parts of castor oil, 150 parts of tall oil, 30 parts of 2,4-toluene isocyanate, 700 parts of fly ash. Such a mixture results in a highly elastic body with a Shore hardness between 30 and 40.
2. 150 Teile Rizinusöl, 75 Teile Tallöldestillat, 75 Teile Perchloräthylen, 60 Teile eines 2,4-Toluidenisocyanats, welches mit Polyalkoholen vernetzt ist, 700 Teile Flugasche.2. 150 parts of castor oil, 75 parts of tall oil distillate, 75 parts of perchlorethylene, 60 parts of a 2,4-toluene isocyanate which is crosslinked with polyalcohols, 700 Parts of fly ash.
