Abstract
The utility model discloses a hollow bolt-grouting anchor cable for mine. The anchor cable is composed of a steel strand, a grouting stop plug, a tray, an anchorage, a screwed plug and an anchor cable body, wherein the steel strand is wound in the middle of the anchor cable body, the anchorage, the tray and the grouting stop plug are installed at one end of the anchor cable body sequentially, and the screwed plug is mounted at the top of one end of the anchor cable body. The hollow bolt-grouting anchor cable for mine is provided with convenient construction, timely load bearing and good coal bed and crumbly strata adaptability, simultaneously, a full-size anchoring mode with more reasonable stress is adopted, and the strength of the anchor cable is improved due to usage of novel deformation steel wires.
Description
Technical field
The utility model relates to the anchor pole field, especially relates to a kind of middle spare anchor and annotates Mine anchorage cable.
Background technology
At present, the main resin anchor cable that adopts Φ 15.24, Φ 17.8mm steel strand manufacturing on market, and grouted anchor bar.The former is easy for installation, carry advantage timely, but its supporting capacity is on the low side, and in the heading of less stable, broken rock gangway, because adopt the mode of end anchor to work, its anchoring effect is very poor.Grouting cable anchor (bar) is although can obtain better anchoring effect in the coal seam of broken rock and less stable, and its slurries are very long hardening time, and the interior non-support effect of section hardening time.Middle spare anchor is annotated Mine anchorage cable and is mainly used in supporting and the reinforcings such as mine working, chamber, crosspoint, the reinforcing that also can be used for the geotechnical engineerings such as tunnel, side slope, in employing, spare anchor is annotated the Mine anchorage cable reinforce adjoining rock, anchor cable can in time apply pretightning force after installing on the one hand, for country rock provides Support Resistance; Realized on the other hand the full length fastening of anchor cable by slip casting, the diffusion of slurries is fixed broken, ravelly ground improved globality and intensity and the self-supporting ability of roadway surrounding rock.
The utility model content
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of slurries hardening time of can shortening, and the middle spare anchor that allows cable body keep suitable pretightning force is annotated Mine anchorage cable.
The utility model takes following technical scheme to realize: a kind of middle spare anchor is annotated Mine anchorage cable and is comprised of steel strand, stop grouting plug, pallet, ground tackle, plug and anchor cable body, described anchor cable body middle part is wound with described steel strand, one end of described anchor cable body is equipped with described ground tackle, described pallet and described stop grouting plug successively, and an end end of described anchor cable body pushes up described plug is installed.
Described anchor cable body adopts high strength helical rib compressor wire to compile strand and forms.
Described steel strand adopt hollow structure.
The utlity model has in sum following beneficial effect: for the hardening time that overcomes grouting cable anchor (bar) long, coal seam, the rock stratum weak effect of ordinary resin anchor cable to poor stability, the shortcoming that ordinary resin anchor cable bearing capacity is lower, grouting cable anchor (bar) and resin anchor cable are united two into one, overcome deficiency separately.Thereby produce new-type middle spare anchor and annotate anchor cable, its existing easy construction, carrying in time, also have good coal seam, broken rock compliance, adopt simultaneously that stressed more rational full length fastening mode is worked, anchor cable intensity is because the use of novel deforming steel wire is improved.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, steel strand; 2, stop grouting plug; 3, pallet; 4, ground tackle; 5, plug; 6, anchor cable body.
The specific embodiment
As shown in Figure 1, a kind of middle spare anchor is annotated Mine anchorage cable and is comprised of steel strand 1, stop grouting plug 2, pallet 3, ground tackle 4, plug 5 and anchor cable body 6, described anchor cable body 6 middle parts are wound with described steel strand 1, one end of described anchor cable body 6 is equipped with described ground tackle 4, described pallet 3 and described stop grouting plug 2 successively, and an end end of described anchor cable body 6 pushes up described plug 5 is installed.
Anchor cable body 6 adopts high strength helical rib compressor wire to compile strand and forms.
Steel strand 1 adopt hollow structure, are formed by multiply spiral ribs compressor wire twisting, are divided into anchoring section and slip casting section, and anchoring section steel strand centers is solid reinforcing bar, can realize resin end anchor; Slip casting section steel strand center is hollow section, carries out grouting and reinforcing.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in claim scope of the present utility model.
Claims (3)
1. spare anchor is annotated Mine anchorage cable in one kind, formed by steel strand, stop grouting plug, pallet, ground tackle, plug and anchor cable body, it is characterized in that: described anchor cable body middle part is wound with described steel strand, one end of described anchor cable body is equipped with described ground tackle, described pallet and described stop grouting plug successively, and an end end of described anchor cable body pushes up described plug is installed.
2. a kind of middle spare anchor according to claim 1 is annotated Mine anchorage cable, it is characterized in that: described anchor cable body adopts high strength helical rib compressor wire to compile strand and forms.
