摘要: In a rock anchor bolt a centering member includes an outlet hole for removing any leakage water flowing into a borehole. The rock anchor bolt includes a sealing device provided around the outer end of a tube to seal the borehole watertight as a tightening nut is being tightened, and an outlet tube provided in a casting space between the tube and a drawbar to carry out the leakage water as grouting paste is being injected, the inner end of which outlet tube extends to the vicinity of an expansion member and the outer end of the outlet tube extends out from the outlet hole of the centering member. The tube has one or more first casting holes at the outer end of the tube in the vicinity of the sealing device and one or more second casting holes at the inner end of the tube near the expansion member.

摘要: The invention relates to an arrangement and a method for the high-strength anchorage of a tendon (1) having a tie rod (4) in a structural element (3). To this end, the structural element (3) has a channel (17) in which the end of the tie rod (4) to be anchored is inserted. A force-locked connection with the wall of the channel (17) is created by means of a curable jointing compound (18). According to the invention, the tie rod (4) has at least one circumferential collar (12) in the region of the end to be anchored, which collar has a radial play with respect to the wall of the channel (17). In this way, it is possible to guarantee a high-strength anchorage for tendons (1) even with a short anchorage length in the channel (17).

摘要: An anchoring rod for anchoring in a borehole of a component by means of a curable organic and/or inorganic mortar composition has an attachment region (14) and an anchoring region (12) with a profiled section (16) that interacts with a curable organic and/or inorganic mortar composition which is filled into the receiving bore. The profiled section consists of wider portions that are conically shaped and the diameter of each of which increases in the direction of the free front end of the anchoring rod. The anchoring region is characterized in that the proportion of the separation (p) of the wider portions to the central borehole diameter (d
cut, med ) is 0.40 to 0.60, the proportion of the outer diameter (d
A ) to the core diameter (d
K ) of the wider portions is 1.35 to 1.55, and the cone angle of the wider portions (α) is 22.5° to 27.5°.-

摘要: Ein selbstbohrendes Befestigungselement (11) zur chemischen Verankerung in einem Untergrund (6) weist einen hohlzylindrischen Aufnahmekörper (12) auf, der an einem Ende (13) einen Bohrkopf (16) aufweist und in dem eine auspressbare, aushärtbare mehrkomponentige Masse (26) vorgesehen ist. Die aushärtbare Masse (26) umfasst einen Härter (27) und ein Reaktivharz (28), die getrennt von einander gelagert sind und im gemischten Zustand aushärten. Im Bohrkopf (16) sind Durchtrittsöffnungen (17, 19) für die aushärtbare Masse (26) vorgesehen. Das Reaktivharz (28) umfasst zwei unterschiedliche Formulierungen (29, 30), die hintereinander angeordnet sind, wobei die zweite Formulierung (30) des Reaktivharzes (28), welche im gemischten Zustand mit dem Härter (27) schnell härtet, in Bezug auf die Setzrichtung (S) des Befestigungselementes (11) hinter der ersten Formulierung (29) des Reaktivharzes (28) angeordnet ist, welche im gemischten Zustand mit dem Härter (27) langsamer härtet.

摘要: Für den Einsatz vor allem im untertägigen Bergbau ist ein Bohrlochverschluss 1 vorgesehen, in den ein Statikmischer 20 so integriert ist, dass er die eingedrückten Komponenten immer sicher und gleichmäßig vermischt. Der Statikmischer 20 ist durch eine Sperre 23 so festgelegt, dass er vor allem die Berstscheibe nicht frühzeitig zerstören kann, insbesondere aber dafür sorgt, dass in den Bereichen zwischen Packerrohr 2 und Blähkörper 3 gleichmäßig gemischtes Verfestigungsmaterial eindringt.
