As shown in Fig. 2, being filled with inside stress relief hole 3 after tube wave monitoring device 5 is put into stress relief hole 3
Couplant 4, couplant 4 can be realized by water.The opening of stress relief hole 3 is provided with closeouts 6, prevents couplant 4 certainly
It flows out in stress relief hole 3, and position of the tube wave monitoring device 5 in stress relief hole 3 is consolidated by closeouts 6 simultaneously
It is fixed.Tube wave monitoring device 5 is drawn at the port of end seif-citing rate relief hole 3 after the placement of stress relief hole 3.
As shown in figure 3, tube wave monitoring device 5 includes tube body 8, tube body 8 can be integral type, can also be connected by multi-segment thread real
Existing, tube body 8 preferably uses plastic tube.It is fixed at the port of 8 one end of tube body and receives energy converter 7, tube body 8 is fixed with reception and changes
One end of energy device 7 is first placed into stress relief hole 3.Also be placed with transmitting transducer 11 in tube body 8, transmitting transducer with connect
Receive the setting of the interval of energy converter 7, its spacing 0.6m.The outside of stress relief hole 3 is provided with tube wave detecting instrument, tube wave detecting instrument
It is connect between energy converter 7 by output line 10 with receiving, is connected between tube wave detecting instrument and transmitting transducer 11 by input line 12.It is defeated
Enter line 12 and output line 10 distinguishes the opening output of seif-citing rate relief hole 3, and is connected with external tube wave detecting instrument.In tube body 8
Outer wall on be provided with scale, the convenient depth for going deep into stress relief hole 3 to tube body 8 is grasped.
Deflector hole 9 is offered on the tube wall of tube body 8, the through-hole reality for penetrating the arbitrary shape of tube wall can be used in deflector hole 9
Existing, by the way that deflector hole 9 is arranged, after tube wave monitoring device 5 is put into stress relief hole 3, in stress relief hole 3 couplant
4 can enter tube body 8 in, play transmitting transducer 11 and receive energy converter 7 between and the coupling effect between country rock 1.
As shown in figure 4, the tube wave monitoring method of underground engineering dynamic disaster local solution danger effect, includes the following steps:
Step 1001, stress relief hole 3 is opened up on country rock 1；
In high stress and there is the tendentious country rock region of dynamic disaster, using drilling machine construction stress relief hole 3 and carry out borehole cleaning

Position in discharge hole 3, is monitored point by point, and when being monitored point by point, the distance moved every time is 0.1m, is being surveyed point by point
During examination, couplant 4 should have been filled in stress relief hole 3 always.
Step 1005, the determination of solution danger effect and solution danger region is carried out；
If the loss of water is serious, can illustrate that there are obvious failure evolvements inside country rock 1, indirectly during filling the water (couplant 4)
Illustrate to reach solution danger effect, but can not determine the region for specifically having realized solution danger.The timing really of solution danger region is being carried out, to water filling
Stress relief hole 3 after stabilization is monitored, and is decayed for its tube wave noenergy of complete country rock region, and interface reflection is bright in section
It is aobvious even to have multiple reflections；And for lesion ruptures evolution country rock region according to evolution process its from section inner boundary reflect from more to
Unobvious or even areflexia, tube wave velocities are lower and have energy attenuation etc., can analyze to obtain accordingly and answer in monitoring depth bounds
1 failure evolvement situation of country rock around power relief hole 3 within the scope of 1 meter specifies the solution danger region inside country rock 1.
Step 1006, judge whether to reach expected solution danger intensity；
Whether reach expected solution danger intensity according to solution danger effect reconciliation danger region decision, if reaching scheduled solution danger intensity,
Step 1007 is executed, the intensity if not up to scheduled solution is endangered executes step 1008.
Step 1007, the monitoring of other stress relief holes 3 is carried out；
Tube wave monitoring device 5 is taken out, and is put into other stress relief holes 3 and carries out solution danger monitoring, realizes a wide range of prison of country rock 1
The case where surveying, grasping entire country rock 1.
Step 1008, further implement danger releasing measures；
It is endangered according to the further enhancement stress relief hole 3 of this field conventional means and water filling solution or takes supporting measure in time, with reality
Existing underground engineering wall rock dynamic disaster local solution danger.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But without departing from the technical solutions of the present invention, according to the technical essence of the invention to above embodiments institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection scope of technical solution of the present invention.
