Rock reaming self-locking anchor cable comprising steel strands and manufacturing method of rock reaming self-locking anchor cable

Abstract

The invention relates to a rock reaming self-locking anchor cable comprising steel strands. The rock reaming self-locking anchor cable comprising the steel strands comprises an outer hole, and an anchor cable, a locking head and a split circular pipe which are arranged in the outer hole, wherein the anchor cable is formed by a plurality of steel strands; the steel strands sequentially penetrate through inserting holes in the top part and the bottom part of the locking head, and then clamping pieces are installed for fixing; the top end of the lamelliform part in the split circular pipe is arranged higher than the top part of the locking head; the bottom end of the lamelliform part in the split circular pipe is arranged between the top part and the bottom part of the locking head, and is connected with a hole wall of a bottom reamed hole formed in the bottom part of the outer hole. During manufacturing, the outer hole is firstly formed; the steel strands and the locking head are then assembled and arranged in the outer hole; a pressurization sleeve pipe sleeves the steel strands so as to downwards press the split circular pipe until the front end of the scattered lamelliform part is connected with the hole wall of the bottom reamed hole and an effect of mechanical anchoring is realized; the pressurization sleeve pipe is taken away, and grouting and solidifying are carried out sequentially. The design not only has the chemical grouting anchoring force and mechanical anchoring force simultaneously, but also has strong aging resistance performance and fatigue resistance performance.

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...
