    摘要： According to the invention, a drill rod comprising an inner channel is drilled into the rock. A free-flowing, self-hardening mass is pressed through the inner channel of the drill rod, filling the drilled hole, so that it hardens with the drill rod remaining in the drilled hole. The hardening mass is a mixture of a hardenable plastic and a hardening plastic. Said plastics are supplied to the inner channel of the drill rod over a pre-determined transport time F which corresponds to the hardening time. The hardening time is defined by the selection of the plastics and the mixing ratio thereof such that the transport time essentially corresponds to the hardening time and leads essentially to the flow path of the hardened mixture being completely filled between the mixing point and the output of the drilled hole.

    摘要： The invention relates to a yieldable rock anchor (10) comprising an anchor element (12) extending along a longitudinal center axis (A) and having a first end (14), a second end (16) and an outer surface (18). An anchor plate (20) is attached near the first end (14) of the anchor element, and an anchor head (22) is secured to the first end of the anchor element and adapted to clampingly engage the anchor plate (20). On its outer surface, the anchor element (12) is provided along at least substantially its entire length with a plurality of ribs (24). A plurality of sleeves (26), each sleeve having two opposing ends (28, 30), for covering some of the plurality of ribs is fixedly arranged on the outer surface of the anchor element (12) such that each of the opposing ends (28, 30) at least substantially sealingly engages the outer surface (18) of the anchor element (12).

    摘要： A method for lining a support material in mining and tunnel constructions comprises the steps of: providing a plurality of lay wires in the long direction; providing a plurality of stay wires in the cross direction, the stay wires making intersections with said lay wires; providing knot wires to attach the lay wires to the stay wires in at least some of the intersections so as to form the support material; installing the support material against a ceiling or a wall of a mining or tunnel construction by means of bolts.

    摘要： An anchor (1) for consolidating non-cohesive rock layers or for connecting them to solid rock (2) primarily has the necessary components for realising a stressed or expansion anchor. Furthermore, when a conventional domed plate (10) is used, which reliably transmits the necessary stress forces, it is possible additionally to bond the anchor bar (4) in the drill hole (3) after stressing. To this end, the anchor bar (4) is either constructed with a connecting tube (22) with distributor head (24) or the sheathing tube (11) comprises a top tube (50), these both fulfilling the task of conveying the grout bonding material (12) reliably from the drill hole mouth end of the anchor bar (4) to the rock end (5A) and then diverting it there and returning it to the drill hole mouth, so ensuring complete fixing and sheathing of the anchor bar (4) in the drill hole (3).
