Description

Verfahren zur Bodenverbesserung durch Einbringen oder Verteilen von Flüssigkeiten Die Erfindung betrifft ein Verfahren zur Bodenverbesserung durch Einbringen oder Verteilen von Flüssigkeiten.Method of soil improvement by introducing or distributing Liquids The invention relates to a method for soil improvement by introduction or distributing liquids.

Zur Bodenverbesserung werden zuweilen Flüssigkeiten (Lösungen, Suspensionien und Emulsionen) in den Boden eingedrückt, die allein oder nach Zuführung einer weiteren Flüssigkeit ihren Zustand verändern und durch diese Zustandsänderung oder auch schon allein durch das Vorhandensein die Eigenschaften des Bodens verbessern.Liquids (solutions, suspensions and emulsions) pressed into the soil, either alone or after adding another Fluid change their state and through this change of state or even already Improving the properties of the soil simply by its presence.

Im allgemeinen wird dieFlüssigkeit nachEinführen von Rohren in den Boden durch dieselben eingedrückt. Ist in dem Boden Wasser vorhanden und mindert dieses die Wirksamkeit der Einpreßflüssigkeit, so ist es bekannt, das Wasser durch Absaugen zu entfernen, wobei der Erfolg einer gleichzeitigen Injektion durch Zutagetreten der Einpreßflüssigkeit geprüft werden kann.In general, after pipes have been inserted into the Bottom impressed by the same. Is water present in the soil and reducing it? this is the effectiveness of the injection liquid, so it is known to pass the water through Remove suction, the success of a simultaneous injection being revealed the injection liquid can be checked.

Bei Lockergesteinen kann der Einpreßdruck nicht oder nicht viel größer als das Eigengewicht des über der Einpreßstelle liegenden Bodens sein, weil andernfalls der überlagernde Boden hochgedrückt wird. Diese Einschränkung macht sich besonders unangenehm bemerkbar bei Bodenverbesserungen in Oberflächennähe, wie z. B. unmittelbar unter und neben bestehenden flachen Gründungen, bei Straßen und Flugplätzen, ferner auch bei der Bodenverbesserung an Böschungen. Ebenso erschwert die angezeigte Einschränkung eine oberflächennahe Durchtränkung des Straßenuntergrundes oder Straßenunterbaues zwecks Verringerung der Frostempfindlichkeit.In the case of unconsolidated rock, the injection pressure cannot, or not much, be greater than the dead weight of the floor lying above the injection point, because otherwise the overlying soil is pushed up. This limitation makes it special unpleasantly noticeable in soil improvements near the surface, such as B. immediately under and next to existing flat foundations, near roads and airfields, furthermore also when improving the soil on embankments. The displayed restriction also makes it more difficult a near-surface impregnation of the road subsoil or road substructure to reduce the sensitivity to frost.

Die Erfindung bezweckt, diese Einschränkung zu vermeiden. Dabei soll gemäß der der Erfindung zugrunde liegenden Aufgabe die Flüssigkeit auf einfache Weise in den Boden eingeführt werden, unbehindert davon, ob im Boden Wasser vorhanden ist oder nicht. Diese Aufgabe wird durch ein Verfahren gelöst, bei dem Unterdruck derart angewendet wird, daß eine auf die Oberfläche des zu verbessernden Bodens aufgebrachte Flüssigkeit in den Boden hineingesaugt oder eine in den Boden eingebrachte Flüssigkeit in demselben verteilt wird.The invention aims to avoid this limitation. It should according to the object underlying the invention, the liquid in a simple Be introduced into the soil in a manner that is unaffected by the presence of water in the soil is or not. This object is achieved by a method in which the negative pressure is applied in such a way that one is applied to the surface of the soil to be improved applied liquid is sucked into the soil or one introduced into the soil Liquid is distributed in the same.

Die Anwendung von Unterdruck ist in der Grundbautechnik zwar seit längerem bekannt, sie beschränkt sich aber stets auf das Absaugen freien Grundwassers oder das Verringem des Wassergehaltes des Bodens.The use of negative pressure has been in basic engineering since Known for a long time, but it is always limited to sucking off free groundwater or reducing the water content of the soil.

Da der Unterdruck bei dem Verfahren nach der Erfindung auf den Porenraum des Bodens, erforderlichenfalls nach Einrichtung einer geeigneten Abdichtung an der Bodenoberfläche, ausgeübt wird, ist das Wirksamwerden des Unterdruckes vom Vorhandensein von Grundwasser unabhängig. Es muß auch nicht wie bei dem eingangs erwähnten bekannten Verfahren des Einpressens von Flüssigkeit und gleichzeitigen Absaugens von Wasser ein ununterbrochener Flüssigkeitsstrom bestehen. Allein schon daraus ergibt sich ein weitaus größererAnwendungsbereich des vorliegenden Verfahrens gegenüber dem bekannten.Since the negative pressure in the method according to the invention on the pore space of the floor, if necessary after setting up a suitable seal the soil surface, is the effect of the negative pressure from the presence independent of groundwater. It does not have to be like the known one mentioned at the beginning Process of injecting liquid and simultaneously sucking off water consist of an uninterrupted flow of liquid. From that alone it follows a far greater scope of the present method than that known.
