Abstract
The invention discloses water blocking device in a kind of hole when carrying out surrounding rock failure range detection in uphole for sonic method；Coupling water is limited in length-specific boring along gap range of scatter, couples the diffusion rate of water in effectively controlling boring while stoping coupling water to flow outwardly along holing by it.It is characterized in that: in hole, water blocking device is made up of rubber pneumatic bag (10), air bag protective sleeve cylinder (9) and annular metal hoop (8), blend compounds band (6) is by air bag protective sleeve cylinder colligation steel pipe outside annular metal hoop.It is mainly characterized by: the rubber pneumatic bag with good dilatancy and toughness can be sufficient filling with the space between steel pipe and hole wall；Air bag protective sleeve cylinder can effectively be protected rubber pneumatic bag to avoid because of friction and damage, and ensures that after aerofluxus it effectively restores to the original state；Annular metal hoop and its outside belt effectively can protect sleeve and rubber pneumatic bag position by fixation balloon, prevent from causing its extruding to be stacked because stretching into or extract steel pipe.
Description
In uphole, surrounding rock failure model is carried out when the present invention relates to tunnel (tunnel) tunneling construction
Enclose coupling water leakage stopping technology during detection.
The surrounding rock consolidation that suspension roof support is commonly used when tunnel (tunnel) tunneling construction is arranged
Executing, when selecting rock-bolt length parameter, country rock damage envelope under the influence of development blasting is one
Individual important references index；During i.e. anchor pole is the most effectively anchored at stable rock stratum, it is that can anchor pole fill
The key of support reinforcement shoulder bed effects is waved in distribution.Sonic method is used to carry out formation damage in boring
Range detection is an engineering site method of testing simple and convenient, effective.This technology exists
Bow application in hole time very smooth, but in uphole, during application, relate to couple the Lost circulation problems of water,
On the one hand coupling water flow outwardly along hole under gravity, on the other hand along destroying country rock
Gap is to country rock internal diffusion centered by boring, and coupling water in so causing hole cannot be sufficient filling with
Space between boring and probe, does not reaches test request.Existing leakage stopping technology mainly exists
Aperture arranges water blocking device, to stop coupling water to flow out along hole；But it is to coupling water edge in hole
Gap diffusion in country rock does not has control action.
Can not effectively control uphole couples what water spread along gap for solving existing water blocking device
Deficiency, the technical problem to be solved in the present invention is that design one can effectively control to couple in uphole
Current lose, the water blocking device of diffusion, to ensure that coupling the water yield in uphole meets test request.
In order to solve above-mentioned technical problem, the present invention designs a kind of device of water blockoff in hole,
While effectively stoping coupling water to flow outwardly along boring, will coupling water along gap in country rock
Range of scatter be limited to length-specific boring in, due to coupling water range of scatter no longer be boring
Total length, but slightly larger than in the limited range of probe length, so can ensure that coupling water energy
Borehole space in the range of enough effectively filling tests, meets test request.
The technical solution of the present invention is: utilize rubber pneumatic bag inflation characteristic closure sky
Space between heart steel pipe and hole wall, stops coupling water to flow outwardly along boring, and is set by water blocking device
Put in close proximity to probe lower position so that it is enter together with probe in boring, so can be by coupling
Heshui is limited in length-specific along the scope of country rock gap diffusion in hole.For solving water blockoff dress
Put rubber pneumatic bag when stretching into (or extracting outside hole) in hole to occur due to the concavo-convex friction of hole wall
Breakage event, adds one layer of air bag protective sleeve cylinder with strong elastic outside rubber pneumatic bag；For
Solve air bag protection sleeve and rubber gas when water blocking device stretches into (or extracting outside hole) in hole
Capsule stacks phenomenon, at the hollow steel at rubber pneumatic bag two ends due to hole wall friction to opposite direction extruding
Being fixedly installed annular metal hoop on pipe, annular metal hoop diameter is slightly less than outside acoustic emission probe
Footpath, and be fixed on steel pipe, the distance between two annular metal hoops is slightly larger than rubber pneumatic bag width
Degree, by air bag protective sleeve cylinder sealing compound on the premise of guarantee rubber pneumatic bag air inlet-outlet pipe is unobstructed
With on colligation steel pipe outside annular metal hoop.
Preferably, described rubber pneumatic bag has good inflation and toughness, and has one
Air inlet-outlet pipe；
Preferably, the elasticity of described air bag protective sleeve cylinder is better than rubber pneumatic bag, and has allowed
The dilatancy of limit.
The beneficial effects of the present invention is: can be notable while stoping coupling water to flow out along hole
Reduce along country rock gap the diffusion water yield in country rock, and then reduce output, accelerate work speed
Rate, improves testing efficiency.

Further illustrate the detailed description of the invention of the present invention below in conjunction with the accompanying drawings.
Require on tunnel (tunnel) country rock, set uphole (2) according to design.And uphole (2)
Diameter is to be advisable more than acoustic emission probe (3) external diameter 15mm, and ensures the smooth nothing of hole wall
Pumex, uphole (2) directly degree meets requirement.
Preprepared rubber pneumatic bag (10) is wrapped under acoustic receiver probe 2 (5)
On the middle steel pipe of two the stationary ring ferrules (8) in side, then by air bag protective sleeve cylinder (9)
It is enclosed within the rubber pneumatic bag (10) wound outward, and through air inlet-outlet pipe (7) to rubber pneumatic bag (10)
The a small amount of air of interior press-in, to detect, the ventilation expansion status of rubber pneumatic bag (10) is the most satisfied to be wanted
Ask；After meeting ventilation expansion requirements, with sealing tape (6) by air bag protective sleeve cylinder (9) two
Hold against annular metal hoop (8) outside take-up strap on steel pipe, now should ensure that rubber gas
The aeration of capsule (10) air inlet-outlet pipe (7), can be by again to rubber pneumatic bag (10) after colligation
The mode being pressed into a small amount of gas carries out the detection of air inlet-outlet pipe (7) aeration.Now water blocking device
Install complete.
According to uphole (2) investigation depth, some sections of hollow steel pipes of continued access below water blocking device
(1), and according to test request connecting water pipe, data collecting system is set up.Will probe and water blockoff
It is front that device stretches into uphole (2), first should check whether uphole (2) quality meets job requirement,
Then the probe connected slowly is stretched in uphole (2) with water blocking device by steel pipe, arrive
Behind precalculated position, open water valve water filling in uphole (2), it was observed that water freely flows out uphole
(2), after, in rubber pneumatic bag (10), air it is pressed into through air inlet-outlet pipe (7), until freely
Till the water yield of outflow uphole (2) is obviously reduced, it is then turned on data collection task button,
Preserve data after waveform stabilization to be detected, close Water filling valve afterwards and stop in uphole (2)
Water filling, and open air inlet-outlet pipe (7) valve by rubber pneumatic bag (10) interior gas release, treat
During rubber pneumatic bag (10) interior no pressure, probe is extracted preset length, carry out next measuring point
Surrounding rock failure situation detection work.
Must carry out according to the order of first water filling, rear inflation when calming the anger, must be according to during aerofluxus
First cut off the water, the order of final vacuum is carried out.Before gas is completely exhausted out, must not outwards pull out steel pipe and spy
Head.
