Rock reaming self-locking anchor cable including steel strand and its manufacturing method

Abstract

Rock reaming self-locking anchor cable including steel strands, including the outer hole and the anchor cable, lock head, and split-type circular tube set inside; the anchor cable is composed of multiple steel strands, and the steel strands pass through the lock in turn. Install clips behind the top and bottom holes on the head to fix them. The top of the petal part in the split 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. The bottom of the bottom part is connected with the hole wall of the bottom reaming hole opened at the bottom of the outer hole; when making, first open the outer hole, then assemble the steel strand harness and lock head, and place them in the outer hole, and then put them on the steel strand harness Insert the pressurized sleeve to press down on the split circular tube until the front end of the dissipated petal part is connected with the hole wall of the reamed hole at the bottom to achieve the effect of mechanical anchoring, and then remove the pressurized sleeve, Grouting and solidification. This design not only has chemical grouting anchoring force and mechanical anchoring force, 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 including a steel strand bundle and a manufacturing method thereof, which is specifically suitable for providing mechanical anchoring force on the basis of the original chemical grouting anchorage force and reinforced by a steel strand bundle 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 the stab...
