Description
Technical field
Mine working supporting and Anchorage Technology field are the utility model is related to, particularly mine working, tunnel, side slope
Stop when engineering uses grouting cable anchor slip casting in the sealing of bore inner certain depth and starch, prevent slurries from being leaked out from aperture crack
Hole interior sealing grouting cable anchor.
Background technology
At present, widely used grouting support technology carries out the reinforcing of the geotechnical engineerings such as mine working, tunnel and side slope.Construction
In, grouting cable anchor is generally starched using the seal orifice such as hollow conic rubber stopper or winding veil, the rope made of hemp into whereabouts.When drilling into
Good and this seal orifice in the case that rock layer surface the is smooth method of type is only starched largely effective, but soft broken rock stratum is used
The method of seal orifice, which stops slurry, to be met the requirements.When aperture crack is larger, even if orifice sealing is lived, when slip casting, starches
Liquid can still be leaked out by the crack around aperture, and slurries cannot be effectively by drilling to rock stratum diffusion inside, can not
Ensure that slurries are filled with drilling, reinforce country rock, full length fastening is realized, so as to reduce slip casting effect.In this case, usually
Face seal is carried out using gunite concrete, both increases cost and workload, also reduces speed of application.To solve the above problems,
Carried out many researchs both at home and abroad, it is proposed that bore inner certain depth sealing only slurry method, following patents be exactly one very
Good example.
China《Gazette of Patent for Invention》Disclose the patent of entitled " only slurry grouting cable anchor in hole ", its Application No.：
201210222718.6, Authorization Notice No. be：CN 102704971 B.The purpose is to design only to starch grouting cable anchor in a kind of hole.
It, which is formed, includes hollow anchor cable, Anchor Cable Anchorage, pallet, component and rigidity core pipe is only starched in hole.During rigid core pipe is nested in
The axle center of empty anchor cable and it is located at its underpart.In described hole only slurry component include inner sleeve, outer tube, lock ring metal tube,
Spring-backed quill and hard sleeve.Hard sleeve, spring-backed quill, outer tube are end to end from bottom to top to be sequentially sleeved in hollow anchor cable
On.The lower end of hard sleeve is withstood on above pallet.Lock ring metal tube, inner sleeve and outer tube are in the same of hollow anchor cable
In the section of position.Lock ring metal pipe sleeve is on outer tube.Inner sleeve is sleeved on rigid core pipe position corresponding with outer tube.Inner sleeve
Pipe, outer tube are hose, by lock ring metal tube lock ring one, inside and outside gap of the plug between the steel wire of hollow anchor cable
In.Described inner sleeve, outer tube are silicone tubes.The internal diameter of described inner sleeve is bigger than the diameter of rigid core pipe by 0.2~
0.5mm, 1.0~2.5mm of wall thickness.The internal diameter of outer tube is bigger 1~2mm than the diameter of hollow anchor cable, 1~3.5mm of wall thickness；Tightly
Bind round metal tube internal diameter is bigger 2~3mm than the diameter of outer tube, 2.5~4mm of wall thickness；The outside diameter of spring-backed quill is less than bore diameter
0.5~1.0mm, internal diameter are more than the outside diameter of anchor cable；The outside diameter of hard sleeve is less than or equal to the outside diameter of spring-backed quill, its length
It is limited with exposing aperture no less than 30mm.
Only only slurry component employs inner sleeve, outer tube, lock ring metal tube, resilient sleeve in the hole of slurry grouting cable anchor in the hole
Pipe and hard sleeve structure, and inner sleeve, outer tube by lock ring metal tube lock ring one, plug in the steel wire of hollow anchor cable
Between inside and outside gap in.Drastically increase sealing of hole and only starch effect.
But in actual production, inner sleeve, outer tube can not inevitably cause hollow anchor cable according to the Direction distortion of anticipation
Cannot fill up the material of inner sleeve and outer tube in gap between the steel wire of cable body completely, steel wire gap still have leak,
The possibility of spillage.Have again and be exactly, inner sleeve is covered by steel wire, when being set with outer tube and lock ring metal tube, it is difficult to ensure that outer tube
Aligned with lock ring metal tube with inner sleeve.

Certain depth.Then, elastic packing pipe fitting 25, rigidity promote pipe fitting 26, pallet 3, anchorage 2, are sleeved on rope successively from top to bottom
In the end segment 7 of body 1.By tensioning, anchorage 2, pallet 3 promote rigidity to promote 26 uplink of pipe fitting.Flower-shape seal 12 and rigidity
Pipe fitting 26 is promoted to extrude elastic packing pipe fitting 25, elastic packing pipe fitting 25 deforms.Elastic packing pipe fitting 25 is big with drill holder 17
12 close contact of inner wall and flower-shape seal of diameter segment 19, realizes the sealing to gap between drill holder 17 and cable body 1.
The installation process of hole interior sealing grouting cable anchor.First drill on coal or rock, according to outer spiral shell after the completion of drilling
Line section 21 formerly screws in drill holder 17 in drilling.Then, load quantity of resin powder stick, then with the head sections 5 of cable body 1 be in hole
The end for sealing the resin anchoring section of grouting cable anchor promotes resin explosive roll to go directly foot of hole, is continuing to promote cable body into drilling
While 1, rotate cable body 1 and resin explosive roll is stirred, make resin explosive roll rupture resin outflow, and resin is sufficiently mixed production
Raw solidification, is drilling of the resin anchoring section anchor knot in coal or rock of hole interior sealing grouting cable anchor the head sections 5 of cable body 1
In.Treat the firm anchor knot of the head sections 5 i.e. resin anchoring section of hole interior sealing grouting cable anchor of cable body 1 in the drilling of coal or rock
Afterwards, covered successively from the end of the end segment 7 for being affixed by anchorage of cable body 1 and load onto elastic packing pipe part 25, rigidity propulsion pipe fitting
26th, pallet 3 and anchorage 2.Elastic packing pipe fitting 25 is formerly and rigidity promotes pipe fitting 26 into the enlarged diameter section 19 of drill holder 17
It is internal.With stretch-draw jack tensioning and anchorage 2 is fastened, promoting pallet 3 to be pressed on coal, either rock face or reinforcement pad, complete
The installation process of pore-forming interior sealing grouting cable anchor.Realize anchoring of the hole interior sealing grouting cable anchor to coal or rock face.
Full anchor effect after the slip casting process and grout cures of the hole interior sealing grouting cable anchor of this embodiment is with implementing
Example three is identical.
The applicable cases of the hole interior sealing grouting cable anchor of this embodiment are identical with embodiment three.
