Description
Verfahren zum Befestigen von Ankerstangen in Bohrlöchern Die Erfindung betrifft ein als solches den Gegenstand eines älteren Rechts bildendes, jedoch nicht zum Stande der Technik gehörendes Verfahren zum Befestigen von Ankerstangen ohne Spreizkopf beim Ankerausbau von Grubenräumen in ihren Bohrlöchern über einen Kunststoffkörper, der aus einem in einer durch das Eintreiben der Ankerstange zerstörten Patrone enthaltenen kalt härtbaren Kunststoffmaterial gebildet wird, wobei die durch ihre Mischung miteinander das erhärtende Kunststoffmaterial ergebenden Komponenten, nämlich die Kunstharzmischung als solche und der Härter zeitlich voneinander unabhängig in getrennten Behältnissen in das Bohrlochtiefste eingebracht und dort gemischt werden.Method of fastening anchor rods in boreholes The invention does not concern something which as such forms the subject of an earlier right Prior art method of securing anchor rods without Spreader head for the anchor removal of pit spaces in their boreholes over a plastic body, the one contained in a cartridge destroyed by the driving in of the anchor rod cold-curable plastic material is formed, which by mixing them with one another the hardening plastic material resulting components, namely the synthetic resin mixture as such and the hardener in separate containers independently of one another in terms of time be introduced into the deepest part of the borehole and mixed there.
Die Mischung der Komponenten erfolgt unter gleichzeitiger vollkommener Ausfüllung des Hohlraumes im Bohrlochtiefsten durch Eindrehen der in ihrem Endbereich als Misch- bzw. Preßschnecke ausgebildeten Ankerstange in die Patrone unter der Mitwirkung des hierdurch auf das gemischte Gut ausgeübten Drucks. The mixing of the components takes place with simultaneous perfect Filling the cavity in the deepest part of the borehole by screwing in the end area designed as a mixing or press screw anchor rod in the cartridge under the Contribution of the pressure exerted on the mixed goods.
Durch die Erfindung wird dieses Verfahren insbesondere im Hinblick auf die erzielbare Verankerungswirkung und vor allem die für den angestrebten Erfolg der schnellen Tragwirkung des Ankers wesentliche Verkürzung der Verfestigungsdauer des den Verband zwischen Gebirge und herstellenden Materials verbessert. The invention makes this method particularly with regard to on the achievable anchoring effect and, above all, on the desired success the rapid load-bearing effect of the anchor significantly shortens the consolidation time of the bond between the mountains and the manufacturing material improved.
Gemäß der Erfindung werden, mit dem oben erläuterten Erfolg, als Kunstharzkomponente für den im Bohrlochtiefsten zu bildenden, den Verband zwischen Ankerstange und Gebirge herstellenden Körper Polyester-, Epoxy-, Phenol- oder Polyurethanharze verwendet, die, wie in dem älteren Recht beschrieben, zusammen mit Härte- und/oder Beschleunigungsmitteln in verschiedenen Behältern in das Bohrlochtiefste eingeführt und dort miteinander gemischt werden. According to the invention, with the success discussed above, as Synthetic resin component for the bond between Anchor rod and mountain body producing polyester, epoxy, phenolic or polyurethane resins used, which, as described in the earlier law, together with hardship and / or Accelerators introduced in various containers into the depth of the borehole and mixed with each other there.
Im Falle der vorzugsweisen Verwendung von Polyesterharzen beträgt die anteilige Menge des Härtungsmittels größenordnungsmäßig 8 bis 10e/o, bezogen auf das Kunstharz. In the case of the preferred use of polyester resins the proportionate amount of the hardening agent is of the order of 8 to 10e / o, based on on the resin.
Als Härter werden vorzugsweise Peroxyde, z. B. Peroxides, e.g. B.
Cyclohexanonperoxyd, Benzoylperoxyd oder Methyläthylketonperoxyd, und als Beschleuniger z. B. Dimethylanilin oder Kobaltnaphthenat verwendet.Cyclohexanone peroxide, benzoyl peroxide or methyl ethyl ketone peroxide, and as an accelerator z. B. dimethylaniline or cobalt naphthenate is used.
Als Füllstoffe, deren Zweck insbesondere der ist, das beim Abhärten solcher Kunststoffe unter Umständen auftretende Schrumpfen bzw. Schwinden derselben auszugleichen, kann z. B. Quarzsand in zweckentsprechender Korngröße von 1 bis 3 mm und/oder Glasfasern verwendet werden. Ein Teil der Aufgabe der Füllstoffe wird, wenn die Patrone vorzugsweise aus Glas besteht, durch die Glas splitter, die sich mit dem Kunststoffmaterial mischen, übernommen. Gegebenenfalls können ferner Stoffe, die äthylketonperoxyd, und als Beschleuniger z. B. Di-NH4 HCO3, NaHCO5, Azoisobuttersäurenitril, Terephthalsäurenitrosomethylamid, zugesetzt werden. As fillers, the purpose of which is, in particular, that of hardening such plastics possibly shrinkage or shrinkage of the same compensate, z. B. quartz sand in an appropriate grain size of 1 to 3 mm and / or glass fibers can be used. Part of the job of the fillers is if the cartridge is preferably made of glass, by the glass splinters that are mix with the plastic material, taken over. If necessary, substances the ethyl ketone peroxide, and as an accelerator z. B. Di-NH4 HCO3, NaHCO5, azoisobutyric acid nitrile, Terephthalic acid nitrosomethylamide, can be added.
Selbstverständlich können die vorstehend genannten Zusätze sowohl für sich wie auch in geeigneten Kombinationen angewendet werden. Of course, the additives mentioned above can both can be used individually as well as in suitable combinations.
Es lassen sich durch die Verwendung der erfindungsgemäß zusammengesetzten Kunststoffmischungen Festigkeitswerte der Verankerung erzielen, die die Zugfestigkeit der Ankerstange selbst übersteigen, so daß bei Beanspruchungen des Ankers eher die Ankerstange reißt, als sich die Verankerung im Bohrlochtiefsten löst. It can be through the use of the composite according to the invention Plastic mixtures achieve strength values of the anchoring, which the tensile strength exceed the anchor rod itself, so that when the anchor is stressed rather the Anchor rod tears when the anchorage in the deepest part of the borehole loosens.
Eine weitere zusätzliche oder für sich anwendbare Möglichkeit zur Beeinflussung der Härtungsdauer bzw. zur Beschleunigung des Härtungsvorganges ist die des Vorwärmens der Patrone und/oder der Ankerstange vor deren Einführung in das Bohrloch. Die Anwendung dieser Maßnahme ermöglicht es, auch noch nicht durchgehärtete, bei Raumtemperatur praktisch feste Harze zu verwenden. Another additional or individually applicable option for Influencing the hardening time or to accelerate the hardening process that of preheating the cartridge and / or the anchor rod before inserting them into the borehole. The application of this measure makes it possible, even not yet hardened, to use resins practically solid at room temperature.
Nachstehend werden Ausführungsbeispiele des neuen Verfahrens unter Benutzung verschiedener für seine Durchführung besonders geeigneter Kunstharze gegeben. Embodiments of the new method are shown below Use of various synthetic resins that are particularly suitable for its implementation.

Die Patrone wurde mit einer Mischung aus 30°/o des unter dem Handelsnamen »Vestopal« bekannten Polyesterharzes, 700/( Quarzsand und 2% Dimethylanilin gefüllt. In die Füllung wurde eine mit 80/0 Benzoylperoxyd als Härter gefüllte Glaskapsel von 280 mm Länge und 9 mm Durchmesser eingeführt. Die geschlossene, mit einem Dichtungselement versehene Patrone wurde in ein Bohrloch von 33 mm Durchmesser eingeführt und anschließend die über ihren ganzen Umfang mit Spirairippen versehene Ankerstange unter Drehen mit 100 bis 240 Umdrehungen pro Minute in das Bohrloch gesenkt, hierdurch die Patrone zerstört, die getrennten Komponenten miteinander vermischt und der Härtungsvorgang ausgelöst. Nach 30 Sekunden Eindrehzeit und 30 Minuten Härtungszeit war es möglich, den Anker auf Zug zu belasten, wobei sich eine Haftung von 1,25 t/cm Verklebungslänge ergab. Example 1 A glass cylinder with a wall thickness of 1/2 mm was used as the cartridge, a length of 300 mm and a diameter of 28 mm. The cartridge came with a Mixture of 30 ° / o of the under the trade name »Vestopal« known Polyester resin, 700 / (quartz sand and 2% dimethylaniline filled. The filling was a glass capsule of 280 mm length and filled with 80/0 benzoyl peroxide as hardener 9 mm in diameter introduced. The closed one with a sealing element Cartridge was inserted into a borehole 33 mm in diameter and then the anchor rod, which is provided with spiral ribs over its entire circumference, while turning lowered into the borehole at 100 to 240 revolutions per minute, thereby the cartridge destroyed, the separate components mixed together and the hardening process triggered. After 30 seconds of screwing in and 30 minutes of curing time, it was possible to to load the anchor on tension, with an adhesion of 1.25 t / cm bond length revealed.
Beispiel 2 Als Patrone diente ein auf 1600 C vorgewärmter Glaszylinder der Dimensionen gemäß Beispiel 1, der mit einem Gemisch aus 400/0 des mit dem Handelsnamen »Araldit« bezeichneten Äthoxylinharzes (Epoxyharzes) bekannten Gießharzes E und 60°/o Quarzmehl gefüllt war. In diese Füllung war die zweite Glaskapsel, die 200/0 eines Aminhärtes Typ 943 (°/o bezogen auf das Gießharz) enthält, eingebettet. Die Patrone wurde noch heiß in das Bohrloch eingeführt, die auf etwa die gleiche Temperatur erhitzte, mit Spiralrippen versehene Ankerstange entgegen der Drehrichtung der Spirale drehend in das Bohrloch eingebracht, hierdurch die Patrone zerstört und die Komponenten einschließlich der Splitter der Glaszylinder innig miteinander vermischt. Nach 15 Minuten war der Härtungsvorgang abgeschlossen. Example 2 A glass cylinder preheated to 1600 ° C. served as the cartridge the dimensions according to Example 1, with a mixture of 400/0 des with the trade name "Araldit" designated ethoxylin resin (epoxy resin) known casting resin E and 60% quartz flour was filled. The second glass capsule, the 200/0, was in this filling an amine hardness type 943 (% based on the casting resin). the Cartridge was inserted into the borehole while still hot, at about the same temperature heated anchor rod with spiral ribs against the direction of rotation of the spiral rotated into the borehole, thereby destroying the cartridge and the components including the splinters of the glass cylinder intimately mixed with one another. After 15 The curing process was completed in minutes.
Die sofort vorgenommene Prüfung der Haftung des Ankers ergab einen Wert von 1,70 t/cm Verklebungslänge.The immediate check of the anchor's liability resulted in one Value of 1.70 t / cm bond length.

In diese Füllung wurden zwei weitere Glaszylinder mit nur 8 mm Durchmesser eingebracht, deren einer 60/0 Benzoylperoxyd (O/o bezogen auf das Polyesterharz) und deren anderer Polyesterharz vermischt mit 4°/o Dimethylanilin enthielt. Nach Einführen der Patrone in ein Bohrloch von 33 mm Durchmesser wurde die mit 300 Umdrehungen pro Minute rotierende Ankerstange, die in der Länge der Patrone von der Spitze des Ankers entsprechendem Abstand ein elastisches ringförmiges Dichtungselement trug, in das Bohrloch gesenkt, hierdurch die Patrone zerstört und die Komponenten einschließlich der Glassplitter innig miteinander vermischt. Nach 60 Sekunden Drehzeit und einer anschließenden Härtungszeit von 40 Minuten wurde der Anker auf Zug belastet; die Haftung betrug 1,4 t/cm Verklebungslänge. Example 4 A glass cylinder with a wall thickness of 1 mm was used as the cartridge, 500 mm in length and 28 mm in diameter, which is made with 30 parts of a polyester resin in Example 1 mentioned type and 70 parts of slag powder + NaHCO3 was filled. Two further glass cylinders with a diameter of only 8 mm were inserted into this filling, One of them is 60/0 benzoyl peroxide (O / o based on the polyester resin) and the other Polyester resin mixed with 4% dimethylaniline. After inserting the cartridge the rotating at 300 revolutions per minute was inserted into a borehole 33 mm in diameter Anchor rod corresponding in length to the cartridge from the top of the anchor Spaced an elastic annular sealing element, lowered into the borehole, this destroys the cartridge and the components including the broken glass intimately mixed with each other. After 60 seconds of shooting and a subsequent one Curing time of 40 minutes, the anchor was subjected to tensile stress; the liability was fraudulent 1.4 t / cm bond length.
Beispiel 5 Eine Glaspatrone von 22,5 mm Durchmesser und 260 mm Länge enthält 46 Gewichstteile eines Polyisocyanats. In diese Außenpatrone wird eine Innenpatrone mit einem Durchmesser von 16 mm und einer Länge von 240 mm, die 44 Gewichtsteile einer Polyhydroxylverbindung enthält, eingebettet. Beide Komponenten enthalten Zusätze eines inerten Füllstoffes. Die fertige Patrone wird in ein Bohrloch von 28 mm Durchmesser eingeführt und durch die drehend eingebrachte Ankerstange zerstört, wobei die in der Patrone getrennten Komponenten innig miteinander vermischt werden. Der entstandene Polyurethan-Harzmörtel füllt den Ringraum zwischen Ankerstange und Bohrlochwandung vollständig aus. Example 5 A glass cartridge 22.5 mm in diameter and 260 mm in length contains 46 parts by weight of a polyisocyanate. An inner cartridge is inserted into this outer cartridge with a diameter of 16 mm and a length of 240 mm, the 44 parts by weight a polyhydroxyl compound, embedded. Both components contain additives an inert filler. The finished cartridge is inserted into a borehole 28 mm in diameter inserted and destroyed by the rotating anchor rod, whereby the in the cartridge separate components are intimately mixed with one another. The resulting Polyurethane resin mortar fills the annular space between the anchor rod and the borehole wall completely off.
Nach einer Härtungszeit von 6 Stunden wurde der Anker auf Zug belastet. Die Haftung des Ankers betrug 1,63 t/cm Verklebungslänge.After a curing time of 6 hours, the anchor was subjected to tensile stress. The adhesion of the anchor was 1.63 t / cm bond length.
