<p>The proposed injection cable bolt, for use in particular in mining, tunnelling and slope or embankment construction as well as for securing rock faces, consists essentially of a cable with a core in the form of a highpressure hose and consisting of, for example, heavy-duty synthetic or natural textile yarns. Injection cable bolts of this type are surrounded by a ret-like backing mesh and provided with a securing element, a sealing element and, outside the bove, a connecting element. The securing element (6) is connected to the cable end (7) by a shrinking hose (8), and the sections (16, 17) of the sealing element (15) are designed as two-half shells (18) which can fit together. The interior of the section (16) directed at the mouth of the bore is cylindrical over its entire length, and the section (17) is cylindrical on the outside. The slide-over section (17) has on the inside two opposing conical extensions (23, 24) facing away from the cable (2). The sleeve (26), which can be securely attached to the cable end by shrinkage or with adhesive, at least partially encompasses the connecting element (27), and a tube (28) which can be inserted in the core (3) is arranged in the connecting element (27).</p> |
