  • Composite yieldable rock anchor with improved deformation range
    Patent number: 10697297
    Abstract: The present invention pertains to a yieldable rock anchor (10), comprising an elongated tendon (12) extending longitudinally along a tendon axis (A) from a proximal end (16) to a distal end (18), wherein the tendon includes a substantially non-yielding rigid first anchor portion (20) at or near said distal end (18) and extending towards said proximal end (16), and at least one plastically deformable axially yielding portion (26) intermediate said non-yielding rigid first anchor portion (20) and said proximal end (16). The first anchor portion (20) may be a hollow bar member, and the first anchor portion (20) and the at least one yielding portion (26) are integrally joined or coupled to one another to form at least part of said elongated tendon (12).
