Quality evaluation, the method frequently with boring and coring is analyzed and tested to core;Further, wide variety of rock mass is supervised safely
Survey, be also by setting multipoint displacement meter, bolt stress meters, acoustic emission sensor etc. in drilling and in hole, rock being obtained in real time
The characteristics such as body deformation, stress, micro rupture.
Common boring method has mechanical air drill method and geology to bore method.Air drill method is piston is made back and forth using compressed air
Motion, impact hammer drill mill rock drilling stone, this method can not retain core.It is with steel loop cutting set coring, core that geology, which bores method,
Can completely it retain.But both approaches all can make borehole wall be stained with substantial amounts of rock dust.This rock dust can cover
Small crack, joint, huge puzzlement is caused to method of testings such as borehole cameras inside rimrock body.In rockmass safety monitoring side
Grouting operation will be carried out to make sensor close by being arranged in face, hole after the testers such as multipoint displacement meter, bolt stress meters
Anchor hole wall rock mass.And hole wall powder is easy to make injecting cement paste separate with rock mass, monitoring is caused to fail, instrument is scrapped.In addition,
In some deep rock mass, crustal stress is usually in a higher state, the drilling hole exposed for a long time because of test needs
High stress sillar wall caving and peeling phenomenon unavoidably occur for wall, cause to lose to fall to have many tiny rubbles in hole.These rubbles
There is serious harm for the probe detected in access aperture.Particularly in the test of borehole camera, if probe cloche with
Rubble rubs, and cloche may leave obvious scratch, and the graphical analysis to the later stage brings certain trouble.Therefore,
The rubble in the rock dust and hole of hole wall is cleaned out before test significant.
Effectively to remove the dust and rubble in drilling, existing method mainly has three kinds:One is by clear water hole flushing, the party
Method often results in bottom hole section ponding for drilling diagonally downward, and causes the alluvial of a large amount of dust and rubble, it is impossible to effective borehole cleaning;
Another method is the direct direction push to outside hole in hole with hook, by outside rubble introduction hole, this method is more than 20m in hole
Deep hole in, operator can not accurately manipulate hook outside hole and sight is also restrained;In addition, scene also often take it is another
A kind of method is that rubble is pushed into bottom hole in the lump with easy device, but is the certain of access hole bottom the drawbacks of this method
The drilling of length can not be utilized.More it is essential that usually can be in tomography, crack using the device of constant cross-section size
It is stuck at development, even the device of borehole cleaning is stuck in hole when serious, more serious difficulty is carried out to calibration tape.

Rock debris in engineering the drilling in the prior art, dust etc. can not be efficient, the technical problem of convenient removing;Reach that lifting is removed
The technique effect of effect and operating reliability.
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
State technical scheme to be described in detail, it should be understood that the specific features in the utility model embodiment and embodiment are to this Shen
Please technical scheme detailed description, rather than the restriction to technical scheme, in the case where not conflicting, the application is real
Applying the technical characteristic in example and embodiment can be mutually combined.
Referring to Fig. 1, a kind of full automatic gas pressure hole cleaning device drilled for deep rock mass engineering project, including:Inflatable airbag
1st, pulling force sensor 3, pull bar 2, charge and discharge air pipe 5, air pump 8 and controller 6.
Specifically, the inflatable airbag 1 is connected by the charge and discharge air pipe 5 with the air pump 8;That is, foundation is filled
The inflation/deflation operation structure of gas formula air bag 1, is adjusted with the swelling state for specifically performing inflatable airbag 1, for tackling borehole cleaning mistake
The change in aperture in journey.
The inflatable airbag 1 is connected by the pulling force sensor 3 with the pull bar 2;Applying for pull bar 2 is measured in real time
Power, feeds back to controller 6, for reflecting status of the air bag in hole.And in this, as a Con trolling index, feedback control
The inflation/deflation of air bag, can keep stable pressure, so as to ensure the reliability of elimination effect and clear operation with hole wall.

1 pulling force;The charge and discharge air pipe is connected with the controller, controls inflation/deflation process.
Wherein, during borehole cleaning, inflatable airbag 1 is placed in engineering the drilling 18, under the control of the controller 6,
The air pump 8 is inflated by the charge and discharge air pipe 5, until the inflatable airbag 1 is expanded against the engineering the drilling 18
Hole wall;Then, operate the pull bar 2 to draw the inflatable airbag 1 of swelling state to outside hole, the rubble in hole is promoted to outside hole
Consider dust to be worth doing.
It is necessary explanation, the pulling force sensor 3 monitors the force of pull bar 2 and returns to the controller 6 in real time,
During borehole cleaning, when pull bar 2 is paused suddenly by external force, the stress of pull bar 2 suddenly rises, and pulling force monitor value is more than the first preset value
When, the controller 6 controls the charge and discharge air pipe 5 to release the gas in the inflatable airbag 1, until the pulling force is dropped to
Below first preset value, in this process, operator still applies certain pulling force to pull bar 2, is stranded until inflatable airbag 1 passes through

When the monitor value is 0, the controller control the charge and discharge air pipe keep the pressure constant air pump with it is described
Inflatable airbag connected state;
Wherein, the output pressure of the constant pressure air bag is less than first preset value and more than second preset value.
That is, if when suspending, pulling force sensor is substantially that can't detect pressure in cleanup process, i.e., monitor value is 0,
Now by keeping the unimpeded of loading line, the air pressure of air bag is able to maintain that, is unlikely to release or air pressure is excessive, keeps preferable
Borehole cleaning state, this is the natural gaseous state change shared based on air pressure, efficiently and rapid.
Voltage-controlled system is output it between the first preset value and the second preset value, preferable swelling state can be kept, had
Help maintain the efficiency of borehole cleaning.
