Description
Die Erfindung:The invention:
Die Erfindung betrifft die Herstellung eines Vollstabankers für den Berg- und Tunnelbau, der nach dem Zweiphasen-Ankersetzsystem mit Kleberpatronen, mit einer aufgesetzten Patronen-Wickelfräse ausgerüstet und damit den Patronen-Kunststoffschlauch der 2-K Kleberpatrone von Innen nach Außen ziehamonikaähnlich in der Ankerbohrung zusammengeschiebt, radial aufgeschlitzt und mit den Fräskanten so aufwickelt, dass keine Patronen-Schlauchstücke in die Klebermasse eingemischt und der bisher gefährliche Fingerhandscheneffekt vermieden wird. Mit den durchlaufenden Strömungskanälen in der Wickelfräse für den Patronenkleber, wird der Transport der Klebermischung bis zum Ankerringraum unterstützt und nicht behindert.The invention relates to the production of a Vollstabankers for mining and tunneling, equipped according to the two-phase Ankersetzsystem with adhesive cartridges, with an attached cartridge-Milling cutter and thus pushed together the cartridge plastic tube of the 2-K adhesive cartridge from inside to outside ziehamonikaähnlich in the anchor hole , radially slit and wrapped with the cutting edges so that no cartridge tube pieces mixed into the adhesive mass and the previously dangerous finger-fingering effect is avoided. With the continuous flow channels in the windrower for the cartridge adhesive, the transport of the adhesive mixture is supported to the anchor ring space and not hindered.
Mit der Drehbewegung durch den Bohrmotor der Lafette und dem Vorschub des Vollstabankers in einer Ankerbohrung mit den vorher eingeschobenen Kleberpatronen, wird beim Auspressen das radiale Aufnehmen der Patronenschläuche und die gewünschte Vermischung der 2K-Klebermasse zur Aushärtung ohne den Fingerhandscheneffekt, zur Verbesserung des Verbindungskontaktes des Ankers mit dem Gebirge erreicht und das Verpressen der reinen Klebermischung in angebohrte Klüfte und Spalten über den Ankerringraum mit den geformten Fräsblättern für eine Extruderwirkung, zusätzlich unterstützt.With the rotational movement of the drill motor of the carriage and the feed of Vollstabankers in an anchor hole with the previously inserted adhesive cartridges, when pressing the radial picking up the cartridge tubes and the desired mixing of the 2K adhesive mass for curing without the Fingerhandscheneffekt, to improve the connection contact of the armature reached with the mountains and the compression of the pure adhesive mixture in drilled joints and gaps on the anchor ring space with the shaped Fräsblättern for an extruder effect, additionally supported.
Stand der Ankertechnik:Status of anchor technology:
Anker sind mit/ohne, einem zusätzlichen Klebermagazin, als Injektions- und Vollstabanker zur Stabilisierung von Räumen im Berg- und Tunnelbau, im Tief- und Tagebau, zur Verfestigung und Sicherung von Stützwänden bekannt und in den Schriften
Nach Herstellung der Ankerbohrung werden die 2-K Kleberpatronen mit dem Härterschlauch, bisher nur von einer meißelartig oder schräg angeschärften Schneide aufgeschlitzt und zerstört.After making the anchor hole, the 2-K adhesive cartridges are cut with the hardener hose, previously only by a chisel-like or obliquely sharpened cutting edge and destroyed.
Mit dem Einschieben des Vollstabankers in die vorher mit Kleberpatronen gefüllte Ankerbohrung, wird der Patronenschlauch mit der Schneide nur soweit zerstört, dass sich dieser mit der Klebermischung verwickelt und den erforderlichen maximalen Kontakt zur Erreichung der vorgegebenen Ankertragkraft über den Ankerringraum mit dem Gebirge, fast halbiert.With the insertion of the solid rod anchor in the previously filled with adhesive cartridges anchor hole, the cartridge tube with the cutting edge is destroyed only so far that this entangled with the adhesive mixture and the required maximum contact to achieve the predetermined anchorage force on the Ankerringraum with the mountains, almost halved.
Ein durchgehender Einsatz dieser zweiphasen Ankersysteme in einem vollmechnisierten Vortrieb ist mit der Verwendung einer Patronen-Wickelfräse gesichert, wenn auch unterschiedliche Gebirgsformationen durchörtert werden müssen.A continuous use of these two-phase anchor systems in a fully mechanized jacking is secured with the use of a cartridge-type milling cutter, although different mountain formations must be discussed.
Auf die weiteren Unterscheidungsmerkmale der verschiedenen Ankersetzverfahren, die ausreichend bekannt sind und fast alle mit einem passiv wirkenden Statikmischer ausgerüstet sind, wird hier nicht weiter eingegangen.The further distinguishing features of the various anchorage methods, which are well known and almost all are equipped with a passive static mixer, will not be discussed further here.
Beschreibung und Funktion der Erfindung:Description and function of the invention:
Den vorgegebenen Einsatzbedingungen entsprechend, ist es nahe liegend, einen Vollstabanker mit einer Patronen-Wickelfräse für alle Einsatzfälle zu entwickeln, die den schädliche Fingerhandscheneffekt verhindert. Die Sicherheit des Ankersetzvorganges von Vollstabankern mit einer sauberen Klebermasse wesentlich erhöht und eine sofortige Gewölbebildung im Vortrieb mit dem Extrudereffekt der Fräsblätter unterstützt wird.According to the given conditions of use, it is obvious to develop a solid bar anchor with a cartridge-type milling cutter for all applications, which prevents the harmful finger-sticking effect. The security of the Ankersetzvorganges of solid bar anchors with a clean adhesive mass substantially increased and an immediate vault formation is supported in the drive with the extruder effect of the Fräsblätter.
Der Erfindungsgegenstand ist anhand der Ausführungsbeispiele dargestellt und wird wie folgt beschrieben. Es zeigen:The subject invention is illustrated by the embodiments and will be described as follows. Show it:
Beschreibung:Description:
Weitere Ausführungsformen einer Patronen-Wickelfräse, zur Verhinderung des schädlichen Fingerhandscheneffektes für Vollstabankersysteme mit schraubenförmig gestalteten Fräsblättern, zur Erreichung des Extrudereffektes wurden nicht dargestellt, gehören jedoch zum Bestandteil dieser Erfindung.However, other embodiments of a cartridge tiller, for the purpose of preventing the detrimental finger-sticking effect of solid rod anchor systems having helically shaped cutter blades, for achieving the extruder effect have not been shown but are included in this invention.
