Embodiment Construction

[0028] combine Figure 1-6 The shown anchor cable structure for slope control includes an anchor hole 1 and a plurality of anchor heads 2 sequentially arranged in the anchor hole 1 from the inside to the outside, and of course also includes a steel strand 4, etc. It is connected with the slope protection net, the slope protection frame beam, etc. set on the slope, and the other end extends into the anchor hole 1 and connects with the anchor head 2. Such as Figure 7 and 8 As shown, the slope protection net can adopt a criss-cross grid shape, or a honeycomb shape, etc. At this time, four steel strands 4 and three steel strands 4 are used correspondingly.

[0029] The anchor head 2 is in the shape of a truncated cone, and gradually becomes smaller from one end near the bottom of the anchor hole 1 to the other end, such as figure 1 As shown, that is, the inner end of the anchor head 2 is larger than the outer end, and the inner end is the end near the bottom of the anchor hole...

Abstract

The invention relates to the technical field of slope treatment and aims to provide a high-stability novel slope-treatment anchor cable structure. According to the technical scheme, the novel slope-treatment anchor cable structure comprises an anchor hole and a plurality of steel stranded wires and is characterized in that a plurality of cone-frustum-shaped anchoring heads are sequentially arranged in the anchor hole from inside to outside, and the middle of each anchoring head is provided with a plurality of stranded-wire holes annularly evenly distributed around the center of the anchoring head; each steel stranded wire jointly penetrate the corresponding stranded-wire holes in the anchoring heads, a position, corresponding to the inner end of each anchoring head, of each steel strandedwire is provided with a pier head, and each pier head sleeves the corresponding steel stranded wire and clamps the same; a spiral spring sleeves the steel stranded wire part between each pier head andthe inner end of the corresponding anchoring head, and two ends of each spiral spring are welded to the corresponding anchoring head and the corresponding pier head. The novel slope-treatment anchorcable structure has the advantages that the overall stability of an anchor cable can be increased greatly, and the safety and reliability of a slope protecting system during long-term operation can beincreased.

Description

technical field [0001] The invention relates to the technical field of side slope treatment, in particular to an anchor cable structure for side slope treatment. Background technique [0002] In geotechnical engineering construction, prestressed anchoring technology has become the most common rock and soil reinforcement measure. Prestressed anchor cables can actively reinforce rock and soil, effectively increase the stability and safety factor of rock mass, and ensure the safety of engineering construction and operation period. , which mainly include the following categories: [0003] 1. The first generation of bonded and unprotected prestressed anchor cables; [0004] 2. The second-generation unbonded double-layer protective anchor cable; [0005] 3. The third generation of unbonded pressure dispersion type prestressed anchor cable; [0006] Present these three kinds of anchor cables, its construction technology generally comprises the following steps: offer anchor hole,...
