Description
Technical field
The present invention relates to mine, traffic, water conservancy, engineering field anchor pole.
Background technology
In the fields such as mine engineering, Geotechnical Engineering, Tunnel Engineering, to prevent stratum and surrouding rock deformation or unstability from jeopardizing
Engineering safety is, it is necessary to carry out support reinforcement to stratum country rock, and suspension roof support reinforcement technique is a kind of branch being most widely used
Shield technology.Suspension roof support can fully play the stabilizing power of Rock And Soil itself, but protolith is disturbed small, speed of application is fast,
Securely and reliably, economical and effective, thus in mine support, tunnel support, slope retaining, Large Underground chamber support, and it is all kinds of
It is widely used in building anti-floating, antidumping engineering.Wherein, the support reinforcement effect of grouted anchor bar is compared to common anchor
Bar is more effective.Grouted anchor bar can realize that pressure total length bonds, and both improve anchoring strength, again slurry can be made effectively deeply to enclose
Lithofraction gap, breaking surrounding rock bulk strength, more effective deformation controlling for rock surrounding gateways are improved, and anchor pole encapsulation is good, is not easy by formation fluid
Corrosion.
At present, the grouted anchor bar applied in most of mine and Geotechnical Engineering is all using hydraulic pressure or pneumatic drilling machine as power
Source, after rotary drilling to position of stratum depth, then anchor pole is installed, finally carries out mortar depositing construction operation.Such grouted anchor bar for
Though improve surrouding rock stress environment and improve load-carrying capacity of surrounding rock with obvious effect, country rock body degree of crushing it is high,
Cranny development, country rock from the engineering such as the steady time is short, jewel hole bottom hole rock is hard or it is other in particular cases, have it is following not
Foot：(1) grouting pressure is low, can not effectively go deep into crack, and incompact fractured surrounding rock integral reinforcing effect is poor；(2) anchor pole drilling with
Slip casting is unable to Integral synchronous progress, after typically need to first drilling, extract drilling rod, installing anchor pole, then carries out slip casting operation, causes to apply
The work cycle is grown, and for extremely unstable country rock, easily misses optimal anchoring support opportunity, cause surrouding rock deformation unstability, even
Destroy；(3) in drilling process, the rotary drilling of power source is only relied on, bore bit is small to the impulsive force of bottom hole solid rock, rock drilling
, drilling speed low with efficiency of breaking rock is slow, jewel hole long construction period.Therefore, the practical application promotion effect of grouted anchor bar is not very
Ideal, show as its total length compactness of grouting is not high, and bearing capacity deficiency, working procedure is complicated, and drilling speed is slow, the cycle is grown etc..For
Overcome above mentioned problem, researcher proposes various new grouted anchor bar.
Such as：Chinese invention patent ZL201310096450.0 discloses a kind of perforation major part slip casting constant-resistance anchor pole, exploitation
A kind of anchor pole used of applicable mine particular surroundings, by blasting and perforating device in termination point of anchor rod (in fractured coal and rock) shape
Into blasting and perforating crack or hole, high-pressure slip-casting device is recycled in termination fractured coal and rock（Soft rock）Interior formation major part anchoring anchor
Bar, bottom hole efficiency of breaking rock can be improved to a certain extent, the features such as realizing high-pressure slip-casting, solving existing common bolt should in height
The problem of supporting intensity is low under the complex geological condition of power country rock, soft rock and fragmented rock body.But this kind of anchor pole is using explosion
Means, execution conditions and complex procedures, jewel hole and the construction of slip casting synchronous integrated can not be realized, midway needs more exchange device,
Optimal supporting time may be delayed.
Chinese utility model patent ZL201420048521.X discloses a kind of Self-propelling grouting anchoring-bolt, weak for tunnel
Country rock is constructed and Tunnel Landslide disposal, it can also be used to side slope protection.Grouted anchor bar main body is provided with central slip casting including hollow
The anchor bar body of passage, anchor bar body front end are provided with the cross bit with bit wing sword " 8 ", solve conventional anchor punching, plug
Anchor Agent and anchor pole complicated construction process is put, and can realize that anchor pole closely connects with rock mass total length by the slip casting of hollow bolt body
Touch, when avoiding collapse hole anchor pole be difficult to fill in, Anchor Agent leakiness the problems such as.But this kind of anchor pole can not realize jewel hole and note
Synchronous integrated construction is starched, and the cross bit efficiency of breaking rock of blade " 8 " also has much room for improvement.
Chinese utility model patent ZL201220074667.2 discloses a kind of mining high-voltage water from grouted anchor bar is bored, by anchor
Head, shaft and bearing three parts composition, anchor head are made up of high-pressure water outlet, high pressure water transport pipe and drill bit, and high pressure water transport pipe is placed in
In anchor bar body and drill bit internal, high-pressure water outlet is placed in the front end of drill bit, aids in breakdown rock using water under high pressure and improves drilling speed,
Supporting operating efficiency is improved, the anchor-hold being effectively improved after first anchor-hold and supporting.But this kind of anchor pole water under high pressure breakdown rock
Stone process and slip casting process are separate operations, i.e., first carry out drill bit drilling, and are aided with water under high pressure breakdown rock, then carry out slip casting
Construction operation, anchor pole drilling nor synchronous integrated is constructed, equally exist long construction period, complex procedures are asked with slip casting
Topic, and the drilling process adds water under high pressure broken rock this technical process, and working procedure may be made cumbersome.If cement can be used
Slurry directly substitutes water under high pressure, and realizes synchronous drilling and slip casting operation, it will greatly simplifies working procedure, shortens the time, improves
Drilling speed.
In summary, existing grouted anchor bar, generally existing anchor pole drilling are unable to synchronous integrated construction, construction week with slip casting
The problem of phase is long, complex procedures, and for catalase degree height, cranny development, country rock from the steady time is short, jewel hole bottom hole rock
The supporting effect of hard grade is not satisfactory, and a kind of self-vibration jet grouted anchor bar integrated construction device and method of the present invention can be preferably
Solves above-mentioned supporting problem.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of existing grouted anchor bar, there is provided a kind of self-vibration jet grouted anchor bar integration is applied
Construction equipment, solve catalase degree height in underground engineering, cranny development, country rock from short support issues of steady time, Yi Jikong
