Anti-corrosion anchor cable with measuring and anchoring functions

Abstract

The invention provides an anti-corrosion anchor cable with measuring and anchoring functions. The anti-corrosion anchor cable comprises an anchoring head, a plurality of connecting cables of which one ends are connected with the anchoring head and the other ends are connected with an anchor seat, and a plurality of expansion rings which are arranged on the connecting cables at intervals and are used for fixing the connecting cables, the anti-corrosion anchor cable is characterized in that a cable core is arranged in the middles of the connecting cables and the expansion rings, the cable core is sleeved with a plurality of ball joints at intervals, the cable core between two adjacent ball joints is sleeved with an isolation pipe, the outer parts of the ball joints and the isolation pipes are wrapped with cable core sleeves, one end of the cable core is connected with the anchoring head, and the other end of the cable core penetrates through the anchor seat to be connected with an observer. The displacement can be visually and accurately obtained, the anchoring performance between the anchor cable and surrounding rock can be improved through the ball joints, it is guaranteed that the cable core cannot lose efficacy, the problem that a lock cylinder is corroded by water is solved through the isolation pipe, and the service life of the anchor cable is greatly prolonged due to the fact that an anti-rust layer is arranged on the cable core sleeve.

Description

technical field [0001] The invention relates to an anchor cable, in particular to an anti-corrosion anchor cable with both measurement and anchorage, and belongs to the technical field of hydropower engineering. Background technique [0002] Anchor cable support is one of the important support forms in the field of hydropower engineering. The anchor cable body that can still work stably for a long time in the environment of water seepage and corrosion is the key to the safe operation of underground engineering. As major power stations enter the operation period one after another, real-time monitoring of whether the surrounding rock in the anchor cable anchorage section of the underground powerhouse is deformed is an important link to ensure the safe operation of hydropower projects. The actual monitoring results show that at the initial stage of operation, within about ten years, the deformation of the surrounding rock in the anchorage section is almost zero, but after more ...
