An integrated anchor rod for drilling, injecting and anchoring, comprising a hollow self-drilling rod body, a tray arranged on the hollow self-drilling rod body, a washer and a nut threaded with the hollow self-drilling rod body, and a drill bit is arranged at the front of the hollow self-drilling rod body , the rod body is provided with a plurality of grouting holes; the plurality of grouting holes are arranged crosswise. Grouting through the hollow channel of the anchor rod can cement and solidify the grouting of loose coal and rock, and fasten and stretch accessories such as nut matching trays at the end of the rod body to realize drilling, injection and anchor support for loose coal and rock mass , improve the bearing capacity of the coal body, and increase the support strength of the surrounding rock of the roadway. The utility model has the advantages of compact and simple structure, convenient operation, easy construction and good supporting effect.
Description
Technical field
The utility model relates to a kind of brill and annotates the anchoring integral anchor pole, and the brill that is particularly useful for the loose crushing coal and rock is annotated the anchor supporting.
Background technology
Bolt support technology is by construction and installation anchor pole in coal and rock, improves the coal petrography bearing capacity, forms anchoring body and plays a supporting role.Common anchor pole be coal petrography in section adopt a resin anchoring agent to carry out anchoring.But in some loose crushing coal and rock, construction during armature boring because the unusual difficulty of the loose jewel hole pore-forming of coal body, the hole of normally just collapsing behind the jewel hole, resin explosive roll and anchor pole can't be delivered into boring, cause anchor pole to install.Therefore, need behind jewel hole, can not extract by the body of rod, simultaneously gluing be carried out in loose coal petrography slip casting and solidified, can carry out the fastening stretch-draw of annexes such as the supporting pallet of nut at body of rod afterbody again, realize the brill of loose coal rock mass is annotated the anchor supporting effect.
Summary of the invention
The purpose of this utility model overcomes the weak point in the prior art, and a kind of compact conformation, simple is provided, and effective brill is annotated the anchoring integral anchor pole.
For achieving the above object, brill of the present utility model is annotated the anchoring integral anchor pole, comprise hollow from the drilling rod body, successively be located at the pallet of hollow on the drilling rod body, packing ring and with the nut of hollow from drilling rod body threaded engagement, hollow is provided with drill bit from the front portion of drilling rod body, the body of rod is provided with a plurality of injected holes; Described a plurality of injected hole arranged crosswise.
Beneficial effect: carry out slip casting by the anchor pole hollow channel, can carry out gluing to loose coal petrography slip casting solidifies, can carry out the fastening stretch-draw of annexes such as the supporting pallet of nut at body of rod afterbody again, realization is annotated the anchor supporting to the brill of loose coal rock mass, improve the bearing capacity of coal body, increased the supporting intensity of roadway surrounding rock.Its compact conformation, simple, easy to operate, easily construction, supporting effect is good, has practicality widely.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-afterbody screw thread, the 2-nut, the 3-packing ring, the 4-pallet, 5-hollow is from the drilling rod body, 6-injected hole, 7-drill bit.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Brill of the present utility model is annotated the anchoring integral anchor pole, mainly by hollow from drilling rod body 5, be located at the pallet 4 of hollow on drilling rod body 5, packing ring 3 and constitute successively with the nut 2 of hollow from drilling rod body 5 threaded engagement, hollow is provided with drill bit 7 from the front portion of drilling rod body 5, intersects on the body of rod to be furnished with a plurality of injected holes 6.Hollow is determined according to the hole depth of construction from the length of drilling rod body 5, directly adopts to bore and annotates the anchoring integral armature boring, until desired depth; Annotate anchoring integral anchor pole afterbody at brill and connect the slip casting utensil, carry out slip casting, coal petrography is carried out gluing solidify by the anchor pole hollow channel; Tray 4 and packing ring 3 are fastening from the afterbody screw thread 1 of drilling rod body 5 by nut 2 and hollow then, guarantee that pallet 4 is close to scar.
