Abstract

Die Vorrichtung besteht aus einem Düsenstock (20) und einem Element (26), das zwischen den Rohranfang (11a) eines als Rohr (11) ausgebildeten Felsankers und einer Dichtfläche (24) des Düsenstockes (20) eingesetzt ist. Der Düsenstock (20) umfasst zwei konzentrisch angeordnete Rohre (22, 23) für die getrennte Zufuhr der beiden Kompo­ nenten (B,K) eines Zweikomponenten-Klebstoffes. Das Ele­ ment (26) besteht aus einem plastisch verformbaren Material und weist eine zylindrische, den Rohranfang (11a) umfassen­ de Manschette und einen Flansch (27) auf. Die äussere Wand (22) des Düsenstockes (20) endet in einer Kante (25) als Schnittlinie zwischen einer Kegelfläche und einer Zylinderflä­ che. Im Rohranfang (11a) ist ein statischer Mischer (13) eingesetzt. Durch diese Vorrichtung kann ein Zweikompo­ nenten-Klebstoff mit einem Druck von 120 bar in das Rohr (11) eingepresst werden, um das Rohr und den Zwischen­ raum zwischen Aussenfläche des Rohres und der Wand eines Bohrloches auszufüllen, zum Zweck, einen Schlaffan­ ker zur Festigung von Gestein zu bilden. Das Setzen der Schlaffanker lässt sich dadurch maschinell durchführen. The device consists of a nozzle assembly (20) and an element (26) which is between the pipe start (11a) one as a tube (11) formed rock anchor and one Sealing surface (24) of the nozzle assembly (20) is used. The Nozzle assembly (20) comprises two concentrically arranged Pipes (22, 23) for the separate supply of the two compos elements (B, K) of a two-component adhesive. The Ele ment (26) consists of a plastically deformable material and has a cylindrical, the pipe start (11a) de sleeve and a flange (27). The outer wall (22) of the nozzle assembly (20) ends in an edge (25) as Line of intersection between a conical surface and a cylindrical surface che. In the pipe start (11a) there is a static mixer (13) used. With this device, a two-component nenten adhesive with a pressure of 120 bar in the pipe (11) press fit around the pipe and the intermediate space between the outer surface of the pipe and the wall to fill out a borehole for the purpose of being a sleep fan to form ker for strengthening rock. The setting of the Sleep anchor can be carried out mechanically.
