Factors including the construction mechanical devices, construction basic measures, habits of construction personnel and the like are combined, the 7655 pneumatic rock drill is directly applied to drilling the hole, installing and stirring, construction links are effectively reduced, construction time is saved, construction efficiency is improved, and the efficient novel construction method can be widely applied to supporting mine roadways and chambers by quick and high anchoring force.
Description
Technical field
The invention belongs to the bolt support construction field; Be specifically related to the method for underground constructions employing anchor bolt constructions such as mine working, chamber; When being applicable to supportings such as all kinds of mine workings, chamber; Adopt the resin anchor support form, reach the purpose of quick, big anchored force supporting, guarantee the safe operation of mine working, chamber.
Background technology
At present, China mine becomes to going on foot the mining in the deep gradually, and deep mining is accompanied by a series of problem, and the activity of wherein pressing seems particularly outstanding.Ground pressure activity is a kind of natural phenomena by stress, lithology, rock mass structure control, is the inevitable consequence that production ore is upset stress of primary rock balance.Underground pressure management not only inquires for reason, influence factor, the active mechanism of producing the activity of dried rhizome of rehmannia pressure, and will establish the ground pressure-controlled method that meets mine reality.At present, use at most, the widest ground pressure-controlled method, surely belong to supporting.Bolt support, cable bolting, tunnel-surrounding whitewashing, anchor pole add methods such as steel band (beam) complexed metal net supporting, improve country rock intensity, optimize the country rock stress condition and compose dis environment.
The mechanical characteristic of resin anchor is anchor pole and surrounding rock interaction result, is the mechanics reflection of the practical working situation of anchor pole constraint surrouding rock deformation.Adopt high-strength prestressed anchor pole---resin anchor; Can apply enough pretightning forces to country rock immediately, not only can stop country rock ground initial deformation, can also eliminate the initial slippage of anchor pole self; And can apply certain pretightning force to country rock, the cross section under tension tensile stress of roadway surrounding rock is reduced.Anchor pole has improved the shear strength of country rock greatly to the frictional force that country rock applies certain pretightning force generation, and then has avoided roadway surrounding rock to occur the crack too early, slows down the reduction of country rock.The anchored force of resin anchor is bigger, and the gelling curing rate is fast, can in several hours, obtain higher first anchor ability, thereby produces anchorage effect rapidly, effectively.Because the unrivaled superiority of resin anchor makes it replace traditional anchor pole-friction-type anchor metal (claiming pipe-seam type anchor rod, split anchor pole etc. again) that mine support is adopted gradually.
But the prior resin anchor rod construction process is more loaded down with trivial details, complicated, consuming time than friction-type anchor metal (claiming pipe-seam type anchor rod, split anchor pole etc. again) construction technology.The conventional resins anchor rod construction process adopts 7665 air rock drill borings, installation, stirring etc.7665 hammer drill have been compared following shortcoming with 7655 hammer drill: (1) drilling efficiency is low.The drilling efficiency of 7665 hammer drill is lower than 7655 hammer drill.(2) air leg is unidirectional.In the actual mechanical process, after can often occurring holing, must manual work pack up air leg, waste time and energy.(3) workman is accustomed to using 7655 air rock drills.In resin anchor construction practical operation, mine worker occurs and use the boring of 7655 hammer drill, use the installation of 7665 hammer drill, condition of stirring, the installation labor manpower of wind, water pipe, time etc., operating efficiency is extremely low.Therefore, how to improve a great problem that the resin anchor speed of application becomes the puzzlement mine.
Summary of the invention
The object of the invention is exactly the technology shortcoming loaded down with trivial details, complicated, consuming time that exists to the conventional resins anchor rod construction process, and a kind of new construction method of resin anchor efficiently is provided.
For realizing above-mentioned purpose of the present invention, the method that the present invention adopts adopts following technology, equipment:
(1) select the body of rod of right-handed thread for use, the yield strength of the body of rod is not less than 355MPa, at an end of the body of rod pallet, the hex nut that is complementary with body of rod diameter, thread rotary orientation is installed in proper order, and the body of rod, pallet, hex nut constitute anchor pole;
(2) body of rod afterbody at said anchor pole carries out spot welding, and the thickness of spot welding point is no more than the thickness of hex nut;
(3) with the boring of 7655 air rock drills, after boring finishes, fall water and scum silica frost in the hole clearly, in the hole, fill in resin explosive roll, anchor rod body;
(4) adopt simple and easy connector to connect the hex nut on the hammer drill and the body of rod, be rotated stirring, treat that powder stick solidifies after, with the pneumatic impact wrench nut of screwing, promptly apply certain pretightning force; Described simple and easy connector is to be fixedly connected with drill steel by sleeve to constitute, and the cavity shape of sleeve and hex nut profile are complementary, and the profile of drill steel and the installing hole of hammer drill are complementary.
Described anchor rod body adopts indented bars; The center of said drill steel is provided with water injection hole.
Described pallet is advisable with the butterfly pallet.
Compare with traditional construction technology; Factors such as new construction method integrated construction plant equipment of the present invention, the basic measure of constructing, constructor's custom; Directly use the boring of 7655 air rock drills, install, stir, effectively reduced construction link, practiced thrift the engineering time; Promoted efficiency of construction, for the supporting that guarantees mine working, quick, the big anchored force of chamber provides new method.
