Abstract
The utility model relates to a quick assembling anchoring bolt and a drilling rod used for geotechnical engineering support. The anchoring bolt is composed of a bolt body and a screw thread body positioned at the front section of the bolt body, wherein, the screw thread body is clockwise threads, and the diameter of the screw thread body is matched with the hole diameter of the anchoring end of a drilling hole of a rock mass. The size of the diameter of the special drill rod is different, the diameter of the front section of the drill rod is smaller than that of the back section of the drill rod, and the diameter of the front section of the drill rod is matched with the hole diameter of the anchoring end of the drilling hole of the rock mass. The utility model having the characteristics of favorable anchoring effect, no need of agglomerant, low cost, high early anchoring strength convenient installation and operation, high installing speed and good supporting effect is particularly suitable for soft coal beds or soft rock.
Description
Technical field
The utility model relates to a kind of Fast Installation anchor pole and the special-purpose drilling rod thereof that uses in the geotechnical engineering supporting.
Background technology
In the rock mass support engineering, existing automatic anchor pole need use resin circle cementing agent to increase anchored force, though anchoring effect is good, but the cost of resin circle is higher, account for the anchor pole cost 30% (cost of general anchor pole is 20 yuan, one resin circle is a 6-7 unit), and resin needs the process of setting of certain hour, can not immediate support; In addition, adopt backpitch to advance the resin circle, in drilling process, cause retreating, need manual feed, so anchored force is under some influence in order in boring, to put into resin circle anchor pole.The bar footpath is consistent before and after the drilling rod of rock body drilled use simultaneously, just need change the different drilling rod of thickness for getting out the different boring in aperture, and is very inconvenient during work.
Summary of the invention
Be to provide low, the early stage anchoring strength height of a kind of cost, anchor pole and special-purpose drilling rod thereof easy to install in order to overcome above-mentioned defective the purpose of this utility model.Its anchoring effect is good, need not cementing agent.
The utility model is realized as follows for achieving the above object: it is made up of the body of rod, the threaded body that is positioned at body of rod leading portion, and described threaded body is a right-handed screw, and the aperture of its diameter and rock body drilled anchored end is complementary.
The slightly larger in diameter of above-mentioned threaded body is in the aperture of rock body drilled anchored end.
The bar of the special-purpose drilling rod of above-mentioned anchor pole directly differs in size, and leading portion bar footpath is less than back segment bar footpath, and its leading portion bar footpath is complementary with the aperture of rock body drilled anchored end.
The utility model compared with prior art, the anchor pole leading portion is a backpitch, its leading portion rock body drilled aperture is little, anchorage head spiral part directly incision combines with rock mass, strengthen anchored force, thereby when anchor rod anchored, need not any cementing agent, not only reduced engineering cost, also can directly reach the high country rock quick anchoring of early strength, in time play supporting effect; Simultaneously, need not to change the drilling rod of different-diameter during rock body drilled, once adopt the special-purpose drilling rod of reducing, quick and easy to use.Therefore the utlity model has the characteristics that cost is low, fast by dress speed, supporting effect is good, be specially adapted to soft seam or soft rock.
Description of drawings
Fig. 1 is the utility model anchor structure schematic diagram;
Fig. 2 is the special-purpose drilling rod structural representation of the utility model;
Fig. 3 is the utility model scheme of installation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1,3: the utility model anchor pole is made up of the body of rod 1, the threaded body 2 that is positioned at the body of rod 1 leading portion, threaded body 2 is a right-handed screw, the aperture of its diameter and rock body drilled 3 anchored end 5 is complementary, combine with rock mass in order to make anchor rod anchored head thread body 2 directly cut rock body drilled 3, strengthen anchored force, the slightly larger in diameter of threaded body 2 is in the aperture of rock body drilled 3 anchored end 5.Here threaded body 2 is spiral helicine self tapping screw thread, and its screw thread can be welded or the body of rod 1 adds and once casts man-hour with hand-drawn wire.
Referring to 2,3: the bar of the special-purpose drilling rod 4 of the utility model directly differs in size, its leading portion bar footpath 6 is less than back segment bar footpath, leading portion bar footpath 6 is complementary with the aperture of rock body drilled 3 anchored end 5, combine with rock mass in order to make anchor rod anchored head thread body 2 directly cut rock body drilled 3, strengthen anchored force, leading portion bar footpath 6 is the same with the aperture of rock body drilled 3 anchored end 5.
Referring to Fig. 3: in the anchor pole installation process, in rock mass, get out the boring 3 of different-diameter earlier with special-purpose drilling rod 4, again anchor bar body is inserted, because the slightly larger in diameter of anchor rod body 1 leading portion threaded body 2 is in the aperture of rock body drilled 3 anchored end 5, threaded body 2 is a right-handed screw simultaneously, therefore, anchorage head threaded body 2 can directly screw in the anchored end 5 and rock mass strong bonded of rock body drilled 3.
