Embodiment Construction

[0028] Combine Figure 1-6 The shown a new type of anchor cable structure for slope treatment includes an anchor hole 1 and a plurality of anchor heads 2 arranged in the anchor hole 1 from the inside to the outside. Of course, it also includes steel strand 4, etc., steel strand 4 One end is connected with a slope protection net, a slope protection frame beam, etc. set on the slope, and the other end extends into the anchor hole 1 and is connected with the anchor head 2. Such as Figure 7 with 8 As shown, the slope protection net may adopt a crisscross grid shape, or a honeycomb shape. In this case, four steel strands 4 and three steel strands 4 are respectively used.

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

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 a novel side slope treatment anchor cable structure. Background technique [0002] In the construction of geotechnical engineering, pre-stressed anchoring technology has become the most common rock-soil reinforcement measure. Pre-stressed anchor cables can actively reinforce the rock-soil mass, effectively increase the stability safety factor of the rock mass, and ensure the safety of engineering construction and operation. , Which mainly includes 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 unbonded pressure dispersion prestressed anchor cable; [0006] The construction process of the current three types of anchor cables generally includes the following steps: opening an anchor hole, placing an anc...
