The proposed injection cable bolt, for use in particu- lar in mining, tunnelling and slope or embankment con- struction as well as for secur- ing rock faces, consists es- sentially of a cable with a core in the form of a high- pressure 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).
L'invention concerne un tirant de câble d'injection, destiné notamment à l'exploitation minière, à la construction de tunnels et à la création de talus, ainsi qu'à retenir des filets anti-éboulements. Ce tirant de câble d'injection comprend essentiellement un câble réalisé dans des fils textiles à haute performance, tels que des fibres synthétiques et/ou naturelles, et comportant une âme se présentant sous forme de tuyau souple flexible à haute pression. Les tirants de câbles d'injection de ce type sont entourés d'un treillis réticulée et comportent un élément de retenue, un élément d'étanchéité et un élément de raccordement placé en dehors du trou. L'élément de retenue (6) relié à l'extrémité du câble (7) à l'aide d'un tuyau souple contractile (8). Chacune des sections (16, 17) de l'élément d'étanchéité (15) est formée de deux semi-coques (18). La face intérieure de la section (16) orientée en direction de l'embouchure du trou est cylindrique sur toute la longueur et la face extérieure de la section enfilable (17) est cylindrique. La face intérieure de la section enfilable (17) comporte deux extensions (23, 24) coniques opposées éloignées du câble (2). Le manchon (26) solidarisable avec l'extrémité du câble (25) par contraction ou par collage enserre au moins en partie l'élément de raccordement (27) et une tubulure (28) insérable dans l'âme (3) est montée dans ledit élément de raccordement (27).
