Aus
Das bekannte Dichtungsmittel eignet sich sehr gut zur Bildung von Wassersperren (waterproof barriers) in Felsenspalten und auf losen Böden gemäß der Injektionsmethode und auf losen Böden gemäß der Methode der Tiefbodenmischung (Deep Soil Mixing).The known sealant is very well suited to the formation of waterproof barriers in clefts of rock and on loose soils according to the injection method and on loose soils according to the method of Deep Soil Mixing.
Aufgrund seiner rheologischen und strukturmechanischen Eigenschaften garantiert dieses bekannte Mittel nicht unter alle geologischen Bedingungen die Dichtigkeit der Wassersperre, wenn zuvor angefertigte Löcher, Spalten, Gräben, Baugruben oder ähnliche, insbesondere enge und tiefe Vertiefungen mit der Suspension dieses Mittels gefüllt werden.Due to its rheological and structural mechanical properties, this known means does not guarantee the tightness of the water barrier under all geological conditions when previously prepared holes, cracks, ditches, excavations or similar, in particular narrow and deep depressions are filled with the suspension of this agent.
Die Aufgabe der Erfindung besteht darin, ein wassersperrendes Dichtungsmittel anzugeben, das verbesserte Dichtungseigenschaften aufweist und einfach handhabbar ist.The object of the invention is to provide a water-barrier sealant which has improved sealing properties and is easy to handle.
Unerwartet stellte sich heraus, dass der Zusatz von Flugasche und Steinstaub mit ähnlicher Granulation als Füllstoffe des bekannten Dichtungsmittels, das aus einer Wassersuspension aus Lehm und Zement besteht, bei gleichzeitiger Modifikation seines Suspensionsbestandes, die Herstellung eines wirksamen wassersperrenden Dichtungsmittels nach einem Verfahren erlaubt, bei dem vorher im Boden gefertigte Vertiefungen mit einer Dichtungsmittelsuspension ausgefüllt werden.Unexpectedly, it has been found that the addition of fly ash and stone dust with similar granulation as fillers of the known sealant consisting of a water suspension of clay and cement, while modifying its suspension inventory, allows the production of an effective water-barrier sealant by a process in which previously made in the soil wells are filled with a sealant suspension.
Für die Zusammensetzung der Suspension wird Lehm verwendet, dessen granulometrierter Bestandteil aus mindestens 60% < 5 μm Teilen gebildet wird und in dessen Mineralbestand Kaolinit, Hydroglimmer (hydromica) und Quarz enthalten sind. Im chemischen Bestandteil beträgt der Gehalt an Al2O3 20–28% und der Gehalt an SiO2 50–60%, mit einer Austauschkapazität von 15–30 mEq (milligramme equivalent units) pro 100 g Trockenlehm und einem Hauptbestandteil (core composition) an Austauschkationen Ca2+ > Na+ > K+ > Mg2+.For the composition of the suspension clay is used, the granulometrierter component of which is formed from at least 60% <5 microns parts and in the mineral inventory of kaolinite, hydro mica (hydromica) and quartz are included. In the chemical component, the content of Al 2 O 3 is 20-28% and the content of SiO 2 is 50-60%, with an exchange capacity of 15-30 mEq (milligram equivalent units) per 100 g of dry clay and a major component (core composition). on replacement cations Ca 2+ > Na + > K + > Mg 2+ .
Im Bestand des Mittels befindet sich vorzugsweise Portlandzement oder ggf. gegen Sulfate resistenter Portlandzement, oder aber Zement mit niedrigem Aluminiumgehalt und Aluminiumoxid.In the stock of the agent is preferably Portland cement or possibly against sulfate-resistant Portland cement, or cement with low aluminum content and alumina.
Der Wassergehalt in der Lehmsuspension ist vorzugsweise so angepasst, dass die Dichte einer frisch angefertigten Suspension des Dichtungsmittels nach der Vermischung aller Bestandteile 1,40 bis 1,65 Mg/m3 und vorzugsweise nicht weniger als 1,45 Mg/m3 beträgt.The water content in the clay suspension is preferably adjusted so that the density of a freshly prepared suspension of the sealant after mixing of all components is 1.40 to 1.65 Mg / m 3 and preferably not less than 1.45 Mg / m 3 .
Das erfindungsgemäße Dichtungsmittel ist kostengünstig, leicht vor Ort auf der Baustelle anzurichten und einfach im Gebrauch. Seine rheologischen und strukturmechanischen Eigenschaften erlauben die Bildung von wirksamen Wassersperren. Die durchgeführten praktischen Versuche haben gezeigt, dass 28 Tage nach der Einrichtung von Gegenfilter-Wassersperren aus dem erfindungsgemäßen Dichtungsmittel, diese über eine Widerstandskraft gegen Axialpressung von wenigstens 0,3 MPa, und einen Filtrationskoeffizient der weniger als 1 × 10–8 m/s betrug, verfügten.The sealant of the present invention is inexpensive, easy to set up on site and easy to use. Its rheological and structural properties allow the formation of effective water barriers. The practical experiments carried out have shown that 28 days after the establishment of counter-filter water barriers of the sealant of the invention, it had an axial pressure resisting force of at least 0.3 MPa and a filtration coefficient of less than 1 × 10 -8 m / sec , decreed.
Die Erfindung wird genauer anhand folgender Beispiele beschrieben.The invention will be described in more detail by way of the following examples.
Beispiel IExample I
Das wassersperrende Dichtungsmittel enthält 7 Gewichtprozent Portlandzement, 52 Gewichtprozent Mischung aus Flugasche und Steinstaub und 41 Gewichtprozent Tonlehm-Wassersuspension.The waterproofing sealant contains 7% by weight Portland cement, 52% by weight mixture of fly ash and stone dust and 41% by weight clay water suspension.
Zur Anfertigung des Dichtungsmittels kann beliebiger Steinstaub mit einer Flugascheähnlichen Granulation, z. B. Kalkstaub, Basaltstaub, oder Dolomitstaub verwendet werden.To prepare the sealant can any stone dust with a fly ash-like granulation, z. As lime dust, basalt dust, or dolomite dust can be used.
Der verwendete Lehm zeichnete sich dadurch aus, dass sein granulometrierter Bestandteil aus mindestens 60% < 5 μm Teilen gebildet wurde, in dessen Mineralbestand sich Kaolinit, Hydroglimmer und Quarz befanden, in seinem chemischen Bestandteil betrug der Gehalt an Al2O3 20–28% und der Gehalt an SiO2 50–60% und dessen Austauschkapazität belief sich auf 15–30 mEq pro 100 g Trockenlehm und der Hauptbestandteil an Austauschkationen Ca2+ > Na+ > K+ > Mg2+.The clay used was characterized by the fact that its granulometric component was formed from at least 60% <5 μm parts, in whose mineral constituents were kaolinite, hydrogels and quartz; in its chemical constituent, the content of Al 2 O 3 was 20-28%. and the content of SiO 2 50-60% and its exchange capacity was 15-30 mEq per 100 g dry clay and the main component of exchange cations Ca 2+ > Na + > K + > Mg 2+ .
Das Mittel eignet sich zur Anwendung bei Bedingungen, die sauberen und schwach mineralisierten Gewässern entsprechen.The product is suitable for use in conditions that correspond to clean and slightly mineralized waters.
Das Dichtungsmittel wird auf dem Gelände, unweit der Stelle, wo die Wassersperre aufgebaut werden soll, unter Anwendung folgender Werkzeuge angefertigt:
- – ein Bohrschlammmischer-Set;
- – Wuchtsiebe zur genauen Ablösung von Gestein, Sand und anderen Teilchen aus der Wasser-Lehm-Suspension;
- – ein Suspensionsbehälter/Sammelbehälter;
- – ein Pumpen- und Rohrenleitungen-Set zum Auspumpen der Suspension und zur entsprechenden Wasserversorgung;
- – ein Silo mit einer Aufgabenvorrichtung für Flugasche und eventuell ein zusätzlicher Silo mit einer Aufgabevorrichtung für Steinstaub;
- – ein Silo mit einem Zementspeiser;
- – ein Schaufelmischer;
- – ein Tank zum temporären Speichern der Dichtungsmittelsuspension
- A mud mixer set;
- - Soil sieves for the exact detachment of rock, sand and other particles from the water-clay suspension;
- - A suspension container / collection container;
- - a pump and tubing set for pumping out the suspension and the corresponding water supply;
- A silo with a fly ash task and possibly an additional silo with a stone dust feeder;
- - a silo with a cement feeder;
- - a paddle mixer;
- A tank for temporarily storing the sealant suspension
Das Dichtungsmittel wird in zwei Schritten angefertigt.The sealant is made in two steps.
Im ersten Schritt wird eine Basis-Lehmsuspension mit einer Dichte von ca. 1,18 Mg/m3 angefertigt. Zu diesem Zweck wird der Bohrschlammmischer mit einer abgemessenen Menge Wasser aufgefüllt und, während das Gerät arbeitet, wird nach und nach eine abgemessene Menge Lehm hinzugefügt. Die Mischung wird fortgesetzt. Ab und zu werden Proben für eine Suspensionsdichtemessung entnommen. Im Laufe des Verfahrens wird ggf. Wasser hinzugefügt, damit eine Basissuspension von geplanter/gewünschter Dichte entsteht.In the first step, a base-clay suspension with a density of about 1.18 Mg / m 3 is made. For this purpose, the mud mixer is filled up with a measured amount of water and, while the equipment is working, a measured amount of clay is gradually added. The mixture is continued. From time to time samples are taken for a suspension density measurement. If necessary, water is added during the process to produce a base slurry of planned / desired density.
Der Prozess der Anfertigung der Basissuspension ist beendet, wenn sich die erreichte Dichte der Lösung stabilisiert hat und der geplanten Dichte entspricht.The process of preparing the base suspension is completed when the achieved density of the solution has stabilized and corresponds to the planned density.
Als nächstes wird eine Portion der Basissuspension abgegossen und über Wuchtsiebe in den Sammelbehälter abgeführt. Dann wird das ganze beschriebene Anfertigungsverfahren so oft wiederholt, bis sich im Sammelbehälter die benötigte Menge der Lösung angesammelt hat. Um während der Herstellung der neuen Portionen eine Sedimentation der im Behälter gesammelten Suspension zu vermeiden, wird diese zyklisch durch einen geschlossenen Behälter-Pumpe-Behälter-Kreislauf gepumpt. Die Vorbereitung der Suspension des fertigen Dichtungsmittels findet in der zweiten Phase, unmittelbar vor seinem Einsatz beim Bau einer Wassersperre (eines Hydroisolations-Diaphragma), statt.Next, a portion of the base suspension is poured off and discharged through balancing sieves in the collection. Then the entire manufacturing process described is repeated until the required amount of solution has accumulated in the sump. In order to avoid sedimentation of the suspension collected in the container during production of the new portions, it is cyclically pumped through a closed container-pump-container cycle. The preparation of the suspension of the finished sealant takes place in the second phase, just prior to its use in the construction of a water barrier (a hydro-isolation diaphragm).
Zu diesem Zweck wird eine abgemessene Menge Basissuspension mittels einer Pumpe in den Bohrschlammmischer geleitet und eine fest eingeplante Menge Zement hinzugefügt. Die Lösung wird mindestens 5–10 Minuten gemischt, danach, ohne den Prozess zu unterbrechen, fügt man schrittweise abgemessene Mengen Flugasche mit Zusatz von Steinstaub hinzu. Zyklisch werden Proben für die Dichtemessung entnommen.For this purpose, a measured amount of base suspension is pumped into the mud mixer and a fixed amount of cement is added. The solution is mixed for at least 5-10 minutes, after which, without interrupting the process, gradually added quantities of fly ash with added stone dust are added. Cyclic samples are taken for the density measurement.
Damit die Suspension des Dichtungsmittels die geplante Dichte erreicht, wird eventuell Wasser dazugegeben. Der Anfertigungsprozess wird beendet, wenn sich die Suspensionsdichte der Mischung stabilisiert hat und der geplanten Dichte entspricht.In order for the suspension of the sealant to reach the planned density, water may be added. The manufacturing process is terminated when the suspension density of the mixture has stabilized and corresponds to the planned density.
Weiter wird das fertige Dichtungsmittel im zweiten Sammelbehälter gesammelt, von wo es mittels der Pumpe über die Rohrleitung bis hin an die Aufbaustelle der Wassersperre geleitet wird.Next, the finished sealant is collected in the second sump, from where it is directed by the pump through the pipe to the construction site of the water barrier.
Nachdem die erforderliche Menge des Dichtungsmittels zugeführt wurde, oder nach einer Unterbrechung des Zufuhrvorgangs, die länger als 15–20 Minuten dauert, werden die Pumpe, die Rohrleitung und der Sammelbehälter für das fertige Dichtungsmittel mit Wasser ausgespült.After the required amount of sealant has been supplied, or after an interruption in the feed process that lasts longer than 15-20 minutes, the pump, tubing, and receiver for the finished sealant are rinsed with water.
