Description
Verfahren zur Verfestigung von Gebirgsschichten. Gegenstand der Erfindung bildet ein Verfahren zum Verfestigen von quarzhaltigen Gesteinen, das dadurch gekennzeichnet ist, daß man durch Einwirken von löslichen Salzen oder Säuren auf kieselsäurehaltiges Material freie Kieselsäure bildet.Method for consolidating rock layers. Subject of the invention forms a method for consolidating quartz-containing rocks, which is characterized by is that by the action of soluble salts or acids on silicic acid Material forms free silica.
Es ist schon bekannt, durch Einführung von aufeinander wirkenden Chemikalien in lockeres Gebirge, die Poren zu verstopfen und dadurch dem Gebirge eine gewisse Standfestigkeit zu geben.It is already known from the introduction of interacting chemicals in loose mountains to clog the pores and thereby give the mountains a certain To give stability.
Es ist nun gefunden worden, daß man eine Verkieselung quarzhaltiger Gebirgsmassen erreichen kann, die an Festigkeit dem natürlichen quarzhaltigen Gestein nicht nachsteht. Die Erfindung schließt hierbei an geologische Vorgänge an, bei welchen eine Verkieselung loser quarzhaltiger Gebirgsarten stattgefunden hat. In ähnlicher Weise wird erfindungsgemäß durch Einwirkung von Chloriden oder sonstigen geeigneten chemischen Verbindungen auf kieselsäurehaltige Stoffe eine Anreicherung von Kieselsäure erzielt, deren Einwirkung auf die Gebirgsschichten die gewünschte Verfestigung hervorruft.It has now been found that a silicification of quartz-containing Mountain masses can reach the strength of the natural quartz-containing rock not inferior. The invention is based on geological processes which a silicification of loose quartz-bearing mountain species has taken place. In The invention is carried out in a similar manner by the action of chlorides or others suitable chemical compounds on silica-containing substances an enrichment achieved by silica, the desired effect of which on the mountain strata Causes solidification.
Erfindungsgemäß wird das quarzhaltige Gebirge mit kieselsäurehaltigen Stoben imprägniert, und lösliche Salze außerhalb des DurchtränkUngsbereiches des kieselsäurchaltigen Matetials in den .Gebirgskörper eingeführt. Die Salzlösungen dringen von dort aus in breiter H:iche in den Körper ein. Bei Verwendung von. Säuren ist darauf Bedacht zu nehmen, daß ein Überschuß von Säure das zu verfestigende Gebirge wieder zersetzt und etwa vorhandene 'Metallteile angreift. Deshalb «-erden in der Pra-xis Salzlösungen den Vorzug erhalten.According to the invention, the quartz-containing mountains with silicic acid-containing Stoben impregnated, and soluble salts outside the impregnation area of the Silica-containing material introduced into the mountain body. The salt solutions penetrate from there broadly into the body. When using. Acids Care must be taken that an excess of acid affects the rock to be solidified decomposes again and attacks any metal parts that may be present. Therefore «- earth in the In practice salt solutions are given preference.
Treten größere Poren oder Znrischenräume in dem zu verfestigenden Gebirge auf, so bilden sich durch das Aufeinanderwirken von kieselsäurehaltigen Stoffen auf die Salälösungen die bekannten Niederschläge, die eine Bildung freier Kieselsäure verhindern. Um diesen t: belstand zu vermeiden, füllt man. vorteilhaft die Poren der Hohlräume vor Anwendung des vorliegenden Verfahrens mit kieselsäurehaltigem Material aus, so daß auch bei ursprünglichem Vorhandensein größerer Poren oder Hohlräume eine Verfestigung durch Bildung freier Kieselsäure stattfindet.If there are larger pores or central spaces in the area to be solidified Mountains are formed by the interaction of silicic acid Substances on the saline solutions are the well-known precipitates that form free Prevent silica. In order to avoid this dump, one fills. advantageous the pores of the cavities prior to using the present method with silicic acid Material from, so that even with the original presence of larger pores or cavities solidification takes place through the formation of free silica.
