Abstract

A rock reaming self-locking anchor cable including carbon fiber rod bundles, including an outer hole and an anchor cable, a lock head, and a split-type circular tube arranged inside it; wherein, the anchor cable is composed of a plurality of carbon fiber rod bundles, and the carbon fiber rod bundles pass through the lock in turn The top and bottom jacks on the head are installed with clips to fix them. The top of the petal-shaped part in the split-type circular tube is set higher than the top of the lock head, and the bottom end is set between the top and bottom of the lock head, and the petal-shaped part is set between the top and bottom of the lock head. The bottom end of the outer hole is connected with the hole wall of the bottom reaming hole opened at the bottom of the outer hole; during production, the outer hole is opened first, then the carbon fiber rod bundle and the lock head are assembled, placed in the outer hole, and then sleeved on the carbon fiber rod bundle Enter the pressure sleeve to press down the split-type round tube until the front end of the scattered petals is connected with the hole wall of the bottom reaming hole to achieve the effect of mechanical anchoring, and then remove the pressure sleeve, Grout and solidify. This design not only has chemical grouting anchoring force and mechanical anchoring force at the same time, but also has strong aging resistance and fatigue resistance.

Description

technical field [0001] The invention relates to the field of rock-soil anchorage, in particular to a rock reaming self-locking anchor cable comprising carbon fiber rod bundles and a manufacturing method thereof, which is particularly suitable for providing mechanical anchoring force on the basis of the original chemical grouting anchorage force and reinforced by carbon fiber rod bundles Anti-fatigue properties. Background technique [0002] Geotechnical anchoring is an important branch in the field of geotechnical engineering. Geotechnical anchoring technology can fully utilize and improve the self-strength and self-stability of rock and soil, improve the stress state of rock and soil, greatly reduce the volume of structures and reduce the stress of structures. Self-weight, significantly saving engineering materials and improving the safety of the construction process. Geotechnical anchoring technology has become one of the most economical and effective methods to improve t...
