Description
Technical field
The present invention relates to a kind of roadway support instrument, particularly relate to a kind of mining combined anchor.
Background technology
Roadway support mainly provides certain Support Resistance to country rock, or reinforce adjoining rock makes to form back-up coat at country rock superficial part, the dilatation distortion and fragmentation such as its essential is to control the absciss layer of anchorage zone country rock, slip, crack are opened, new crackle generation, the secondary bearing structure that rigidity is larger is formed in anchorage zone, to control the development of plastic zone of surrounding rock, stop rock stratum outside anchorage zone to produce absciss layer, improve the stress distribution in country rock deep simultaneously.Final purpose reduces surrounding rock displacement, keeps adjoining rock stability.Anchor pole is a kind of surrounding rock consolidation support pattern common during the ground surface works such as side slope, ground deep foundation ditch and the underground chamber such as tunnel, stope are constructed.
At present, existing common anchor pole is poor in non-deformability, and easily occurs crackle, and anchor pole there will be spark in the process of tearing, and this is breakneck in highly gassy mine.Existing hollow grouting anchor simultaneously, its external surface generally has screw thread, and hollow interior surface is without screw thread, and wall unevenness is even, and shear strength is poor, and when tunnel top skyhook, anchor pole easily drops out, and can cause casualty accident like this.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mining combined anchor, solves the conventional anchor problem that non-deformability is poor in use, shear strength is poor, fastness is poor.
The technical scheme that the present invention solves the problems of the technologies described above is as follows, a kind of mining combined anchor, comprise combined type adapter sleeve, two ends, described combined type adapter sleeve left and right are connected to the rear hollow grouting anchor body of rod and the front hollow grouting anchor body of rod, the described front hollow grouting anchor body of rod other end is provided with spline and falls snatch, on the described rear hollow grouting anchor body of rod, relevant position is provided with hollow stress release dish, described hollow stress release face left right two ends the described rear hollow grouting anchor body of rod on be arranged with top board and supporting plate respectively, the described rear hollow grouting anchor body of rod outside described supporting plate and described top board is arranged with taper stop grouting plug and locking nut respectively, described rear hollow grouting anchor body of rod rear end is provided with stifled slurry plug.
Further, the surfaces externally and internally of the described front hollow grouting anchor body of rod and the described rear front hollow grouting anchor body of rod all has screw thread.
The beneficial effect of above-mentioned further scheme is: by all arranging screw thread at the surfaces externally and internally of the front hollow grouting anchor body of rod and the rear front hollow grouting anchor body of rod, thus making the uniform wall thickness of anchor rod body, enhancing the shear strength of anchor pole.
Further, described stifled slurry is provided with the external screw thread matched with the internal thread of the described rear front hollow grouting anchor body of rod beyond the Great Wall.
Further, the described rear hollow grouting anchor body of rod between described top board and described locking nut is arranged with pad.
The beneficial effect of above-mentioned further scheme is: by sheathed pad on the rear hollow grouting anchor body of rod between locking nut and top board, can not only ensure that locking nut is engaged more tight with top board, but also prevent top board and locking nut due to time length together with corrosion, for convenience detach
Further, described supporting plate lateral surface is provided with some tooth heads.
The beneficial effect of above-mentioned further scheme is: by arranging some tooth heads at supporting plate lateral surface, and supporting plate can be made better to fit with contact surface, prevents from loosening or movement.
Beneficial effect of the present invention: by installing hollow stress release dish on the rear hollow grouting anchor body of rod, effectively raise the non-deformability of anchor pole, fall snatch by arranging spline at front hollow grouting anchor lever front end simultaneously, then can anchor pole be effectively avoided in use to drop out, enhance the fastness of anchor pole, and shearing strength of anchor rod of the present invention is good.
