Description
Technical field
The utility model relates to mine and geotechnical engineering surrounding rock supporting or reinforces anchor cable, is specifically related to be used in combination so that anchor pole can be brought into play the Combined high-strength grouting cable anchor of anchor pole, anchor cable dual-use function by sleeve pipe and anchor cable.
Background technology
Existent defect all when adopting existing anchor pole, cable bolting and Anchor cable-rod combined supporting, the shortcoming that bolt support exists is that tensile strength and supporting capacity are inadequate.When adopting cable bolting, although can carry out hollow slip casting to anchor cable, the anchorage length of the resin anchoring agent of anchor cable end is uncontrollable, when adopting anchor pole and Application of Combined Support with Anchor, needs the number of boring to increase, and will inevitably reduce the speed of engineering construction.
Summary of the invention
In order to solve the problem of above-mentioned existence, design a kind of novel combination type high strength grouting anchor cable, purpose provides the anchor cable that a kind of tensile strength is large, supporting capacity is strong, anchorage depth is controlled and speed of application is fast.
The utility model Combined high-strength grouting cable anchor, it falls wedge, plastics stirring-head, wedge card, cable body, bunch ring, silk braid by slip casting tube connector, nut, pallet, sleeve pipe, injected hole, swollen shell tooth, taper and forms.Described slip casting tube connector and silk braid weld together, and its diameter of bore is identical with the diameter of silk braid centre bore.Described silk braid is with 7 perimeter holes and a centre bore, 7 perimeter holes can pass 7 strands of steel strand of cable body, 7 strands of steel strand pass behind 7 perimeter holes of silk braid with the overstriking position, and the overstriking position is no more than the entire outer diameter of silk braid, so that nut can be connected on the external screw thread of silk braid by helicitic texture.Described cable body falls wedge and bunch ring with plastics stirring-head, wedge card, taper successively from the end to the afterbody.Described taper is fallen wedge with through hole and groove, and afterbody is with the hole of back taper, and the hole of back taper is that wedge fastens taper and falls wedge and use.With many slurry outlets, and swollen shell tooth is welded on the sleeve pipe on the described sleeve pipe, and swollen shell tooth front end has 3 seams, is mutually 120 °.Described swollen shell cingulum has boss structure, be used for stoping resin anchoring agent to leak outside and affect anchoring effect, between bunch ring and silk braid, leave enough distances, can be so that when the slip casting connector was carried out high-pressure slip-casting, slurries can be ejected in the sleeve pipe from the centre bore of silk braid.
The anchor mechanism of this novel combination type high strength grouting anchor cable: in anchored end, anchor cable forms " external reinforcement arch " structure with stronger bearing capacity under the effect of resin anchoring agent; At free end, the anchor pole that sleeve pipe and anchor cable form acts on country rock by hollow slip casting and becomes one, and forms " external reinforcement arch "." external reinforcement arch " to the suspension function of " interior reinforcing arch ", so that " interior reinforcing arch " bearing structure links to each other with deep wall rock, thereby transfers the supporting capacity of deep wall rock, so that wider country rock carries jointly, guarantees the stable of country rock.
The good effect that the utility model high strength grouting anchor cable is obtained is: anchor pole and anchor cable make up, and have improved tensile strength and the supporting capacity of Combined high-strength grouting cable anchor; By the upper conical position of wedge of control cable body, so that the degree of depth of anchoring section resin anchoring is controlled; In anchored end, can provide powerful anchored force by mechanical anchor and chemical anchoring; Being used in combination of anchor pole and anchor cable, the boring number when helping to reduce Bolt-rope Support has been accelerated the speed of constructing.

The specific embodiment
The utility model Combined high-strength grouting cable anchor comprises that mainly slip casting tube connector (1), nut (2), pallet (3), sleeve pipe (4), injected hole (5), swollen shell tooth (6), taper fall wedge (7), plastics stirring-head (8), wedge card (9), cable body (10), bunch ring (12), silk braid (14) and form.
First step assembling anchor pole
Be provided with plastics stirring-head (8) in the end of anchor cable body (10), at first successively wedge card (9), taper fall wedge (7), (length of sleeve pipe should be set according to the degree of depth of boring and the length of needs anchoring to be welded with the sleeve pipe (4) of swollen shell tooth (6), should be so that swollen shell tooth when being close to wall, pallet is positioned at the wall of boring, and can apply prestressing force) be sleeved on the cable body (1).Subsequently, wedge (7), wedge card (9) are fallen in sleeve pipe (4), taper move to the end that plastics stirring-head (8) is arranged, so that 7 strands of steel strand (15) of afterbody are exposed to the outside of sleeve pipe (4).Behind mobile good sleeve pipe (4), 7 strands of steel strand (15) of cable body (1) afterbody are taken away, pass 7 perimeter holes (16) of silk braid (14), with its end (15) overstriking, overstriking position (15) should be no more than the external diameter of silk braid (14), prevents that nut (2) from can not link together by helicitic texture and silk braid (14) smoothly.With bunch together bunchy wire loop (12) is tightly restrainted with the junction at the position of not scattering in the position of scattering of cable body, between bunch ring (12) and silk braid (4), leave enough distances, can so that the slurries of hollow high-pressure slip-casting be ejected in the sleeve pipe (4) from the inner tube (13) of silk braid.Pallet (3) is sleeved on the silk braid (14) again, subsequently, nut (2) is threaded connection on silk braid (14), slip casting tube connector (1) is welded on the silk braid (14) again, rockbolt installation is finished.
Second step is sent anchor pole in the boring to
The mounted anchor pole of the first step, the resin anchoring degree of depth at first as requested fixes taper with wedge card (9) and falls the position of wedge (7) on cable body (1).Rotating nut (2) promotes pallet (3), sleeve pipe (4) successively subsequently, so that swollen shell tooth (6) is in the state of parting a little open, certain pretightning force of exerting pressure under the drag effect of wedge (7) is fallen in the active force of sleeve pipe (4) and taper.Resin anchoring agent is put into boring, then at the bottom of pushing it to the hole with anchor cable, promotion and rotation anchor cable come the resin anchoring agent in the poke hole, after at the bottom of plastics stirring-head (8) arrives the hole, screw nut (2), be close to hole wall so that swollen shell tooth (6) forces swollen shell to open under the effect of external force, apply mechanical anchoring force to anchor cable, after resin anchoring agent solidifies, can apply again certain chemical anchoring power.
The 3rd step hollow high-pressure slip-casting
When treating that certain distortion occurs country rock, cranny development carries out the hollow high-pressure slip-casting by slip casting tube connector (1) to anchor cable, and slurries can flow to boring in sleeve pipe (4), then be penetrated in the crack of country rock, have increased the globality of country rock.
