Abstract
The utility model relates to a tension dispersion protection anchoring cable, which is composed of an external anchoring head, and an anchoring section. The external anchoring head is composed of a clipping sheet 1, an anchoring plate 2, and a tie plate 3. The utility model is characterized in that two or more than two supporting bodies are distributed on the anchoring section, each supporting body is composed of a steel strand 4 without adhesion, a supporting plate 7, an elastic tie sheet 8, and an extruding sleeve 9, wherein, the supporting plate 7, the elastic tie sheet 8, and the extruding sleeve are orderly sheathed on the steel strand. Because the number of steel strands on each supporting plate is unequal, each steel strand end which is beyond the supporting plate is stripped into a steel strand with adhesion. The utility model has the advantages that the stress distribution is uniform, the anchoring effect and the antiseptic effect are good, the structure is simple, and the construction is convenient. The utility model is widely used as an anchoring cable for protecting and supporting of rock and soil anchoring.
Description
The utility model relates to a kind of protecting anchor cable, particularly the ground anchorage anchor cable.
At present in geotechnical anchor engineering, domestic widely used be pulling force concentrated anchor cable because slurry tensile strength is low, during stretch-draw, slurry tensile stress occurs and concentrates at the interface on anchoring section, and under the excessive action of pulling stress, crackle can appear in the injecting paste material of this part, thereby make slurry lose antiseptic effect to anchor cable, along with stretching force increases, progressive failure appears easily, and then the slurry tensile failure, and progressively move down, until entirely ineffective.
The little pressure concentrated anchor cable that occurs utilized the high advantage of slurry compressive strength rate tensile strength, but also there is the too concentrated problem of stress in anchoring body now.
More than two types of anchor cables owing to all exist stress too to concentrate and skewness, easily cause the ruined problem of slurry, thereby can not play permanent protection and shorten the purpose of anchor cable length.
Japan is a kind of KTB pressure dispersing anchorage cable of development recently, though the problem that counter stress is concentrated has some improvement, and ideal, and complex structure not enough, cost height.
The purpose of this utility model is to concentrate the advantage of tension type and pressure dispersing anchorage cable, provide a kind of and make that stress distribution is more even, the transmission of power more is tending towards rationally, anchor cable structure simply, the pull-pressure dispersed protecting anchor cable of favorable anti-corrosion effect, easy construction.
For reaching above-mentioned purpose, the technical scheme of the pull-pressure dispersed protecting anchor cable of the utility model is: this anchor cable comprises outer anchor head, anchoring section two parts, outer anchor head is by intermediate plate, anchor slab, backing plate constitutes, in being with on the non-bending steel cable of anchoring section, outer support frame, there is guiding cap on the top of its longest steel strand, it is characterized in that: be distributed with two or more supporting bodies on the described anchoring section, each supporting body is by non-bending steel cable and be enclosed within loaded plate on the non-bending steel cable successively, extruded sleeve, elastomeric pad is formed, for pressure is disperseed, the number of non-bending steel cable does not wait on each loaded plate, and the end of every non-bending steel cable exceeds loaded plate and partly peels off to the bonding steel strand are arranged.
Because adopt said structure, the pull-pressure dispersed protecting anchor cable of the utility model has the following advantages:
1, stress distribution is more even, anchoring effect is better;
As previously mentioned, the anchor cable of the utility model has the stressed mechanism of tension and compression decentralized, when applying stretching force with the jack pair non-bending steel cable, having the adhesive section steel strand to bear partly load, slurry tension; When load continues to increase, steel strand are passed to slurry with another part load with the form of compressive stress by extruded sleeve, elastomeric pad, loaded plate, last slurry acts on the soil body (rock mass) in the shear stress mode, like this, load is disperseed and be evenly distributed in the anchoring body by tensile stress and compressive stress, slurry is not destroyed, anchoring effect is good.
2, guarantee the anchor cable life-span, be applicable to permanent protection.Because pressure disperses, slurry can not crack, favorable anti-corrosion effect, has adopted the non-bending steel cable that is with the polyethylene sleeve pipe again simultaneously, has formed multilayer proofing, has played the effect of permanent protection.
3, can shorten anchor cable length.Because stress distribution is even, has given full play to the geotechnical body supporting capacity, thereby can shorten anchor cable length, reduces cost.
4, adopt disposable full hole slip casting, simplified construction sequence, full hole slurry pressurized can be guaranteed anchored force when applying prestressing force.
Below, in conjunction with the accompanying drawings and embodiments, the architectural feature of the pull-pressure dispersed protecting anchor cable of the utility model is further described.

Embodiment
A kind of pull-pressure dispersed protecting anchor cable
As shown in Figure 1, the pull-pressure dispersed protecting anchor cable of the utility model is by outer anchor head, anchoring section constitutes, outer anchor head is by intermediate plate 1, anchor slab 2, backing plate 3 constitutes, be with inner support frame 5 on the non-bending steel cable 4 of anchoring section, outer support frame 6, there is guiding cap 10 on the top of its longest steel strand, be distributed with two or more supporting bodies on the described anchoring section, each supporting body is by non-bending steel cable 4 and be enclosed within loaded plate 7 on the non-bending steel cable 4 successively, elastomeric pad 8, extruded sleeve 9 is formed, every non-bending steel cable 4 ends exceed loaded plate 7 partly peels off to the bonding steel strand are arranged, and promptly the end is divided into by loaded plate 7 has bonding and do not have bonding two parts.
Steel strand number on described each loaded plate does not wait, on the loaded plate of top at least 2, increase progressively successively by 2 multiple from the top to outer anchor head, on the loaded plate of close outer anchor head on the number of steel strand and the outer anchor head number of steel strand consistent.
This anchor cable is furnished with Grouting Pipe 11.
