Description
Technical field
The invention belongs to engineering geology On Microseismic Monitoring Technique field, and in particular to a kind of recyclable repetition of microseismic sensors makes
Microseism monitoring system.
Background technology
Rock (body) deformation failure in engineering construction, particularly rock burst dynamic disaster, can directly jeopardize the safety of engineering
Build, or even devastating impact can be caused, therefore effectively monitoring is carried out and pre- to rock (body) stability and rock burst dynamic disaster
Survey, be one of important content that engineering safety is built.Microseism is used for engineering construction as a kind of important means of non-destructive monitoring
In rock (body) stability and rock burst dynamic disaster monitoring and prediction.
In underground engineering wall rock excavates process of construction, in order to enter to the failure and deformation of surrounding rocks and dynamic disaster that are likely to occur
Row Accurate Prediction, microseismic monitoring sensor needs to be fixed on monitored country rock region in advance before engineering excavation.Utilize microseism
Technology accurately determines the position that may occur surrounding rock failure and dynamic disaster, and microseismic sensors need to be in the form of three-dimensional spatial distribution
It is arranged in around monitored rock mass, and the number of sensors arranged is more, it is more reasonable to be distributed, and monitoring effect is relatively more accurate.
In order to realize to the monitoring in real time of rock excavation process, it is necessary to which before rock (body) excavation, prison is got out in stone (body) using rig
Gaging hole, installs microseismic sensors in monitoring holes.The depth of monitoring holes depends on the buried depth excavated and monitored scope, monitoring holes
Depth increase with engineering buried depth, the increase of monitored scope, some monitoring holes are as deep as tens meters, or even rice up to a hundred.Depth ratio
Larger monitoring holes, it usually needs micro seismic monitoring, and monitoring are carried out to the different parts of monitoring holes using multiple microseismic sensors
Kong Yueshen, the microseismic sensors of installation are more, due to above and below monitoring holes it is difficult to ensure that with one heart, wall surface of the hole be difficult it is smooth always, because
The installation of this microseismic sensors is more difficult.
Microseismic sensors are expensive, in order to fetch sensor after monitoring terminates, and reduce micro- in engineering cost, engineering
The installation at shake monitoring sensor scene, generally using directly microseismic sensors are placed in monitoring holes, is remained by monitoring holes
The medium that is transmitted as signal between rock mass and sensor of water, but this method has the disadvantages that：First, monitoring holes direction must
Must downwards, for fully horizontal or there are the monitoring holes of certain angle upwards, this method is not applied to；Secondly, for tilting or downwards
Monitoring holes, it is necessary to rock mass is relatively complete, monitoring holes interior energy maintains the water of injection without being lost in along the crack in monitoring holes,
Either there is infiltration from inside to outside from monitoring holes, can ensure that sensor is in water all the time, but on-site actual situations are more difficult to be reached
To the requirement；3rd, although the couplant that water can be transmitted as signal, the density of water is relatively low, its laser propagation effect is not so good as
Directly effectively contacted with palisades.4th, because liquid can only transmit compressional wave, it is impossible to transmit shear wave, and scene determines rock rupture
The position of signal generally and must rely on shear wave signal, therefore this method causes a large amount of monitoring signals to be lost, monitoring result it is reliable
Property is substantially reduced.
In order to ensure being placed in monitoring holes efficient coupling between microseismic sensors and monitoring hole wall, have in engineering site
Using the joints cement into monitoring holes, pour sensor and palisades for an entirety.This method has the disadvantage that again：First,
Sensor after pouring is not recyclable, causes financial cost high；Secondly, if pouring rear discovery sensor no signal or signal not
It is good, it is impossible to be checked, in order to ensure monitoring effect, it is necessary to punch and install microseismic sensors again, not only waste time and energy, also
Cause financial cost too high；3rd, cement mortar is injected into monitoring holes, because monitoring holes are deeper, not only sensor mount position
Slip casting effect is difficult to ensure, it is possible that sensor mount position fails to realize the situation of effect slip casting, can cause sensor not
Coupled with monitoring holes palisades and without monitoring signals, and monitoring holes are deeper, pour the cement solidifies after total contraction distortion amount get over
Greatly, the signal transmission cable together with cementitious can bear pulling force because cement shrinkage is deformed, and cause effectively to transmit
Signal；4th, generally moister in monitoring holes, pouring rear cement slurry sets needs longer cycle, and the construction time limit can be caused to prolong
It is long；5th, the explosive in digging process is blown out, it is possible that slip casting face relaxes with rock wall surface, causes monitored signal to transmit
Validity reduction；6th, installation process is time-consuming, laborious, it is necessary to which a series of professional grouting equipments and slip casting personnel are, it is necessary to a large amount of
Manually.
In engineer applied, Simple fixing device is also used, microseismic sensors are fixed in a specific device, Ran Houyong
Rigid non-movable metallic rod, which delivers to microseismic sensors behind installation position, to be fixed, but is had the following disadvantages：First,
This method is usually applicable only to the shallower monitoring holes of depth, and needs monitoring holes concentric, hole wall completely smooth, but practice of construction
Middle these requirements are difficult to ensure；Secondly, erecting device size is big, is only applicable to the monitoring holes being relatively large in diameter, cause monitoring holes into
This height；3rd, whole transmission pole and mounting structure are to be inserted into by applying pressure hardness in monitoring holes in monitoring holes, not only
Frictional force is big, and easily grind away cable or microseismic sensors are also easy to be snapped in monitoring holes in privileged site, it is impossible to deliver to specific
Installation position；4th, installation process is time-consuming, laborious, it is necessary to expend a large amount of artificial.These above-mentioned problems, cause microseismic sensors
It is restricted in the monitoring holes larger applied to depth ratio.
Thus, it is how convenient, effectively microseismic sensors are arranged in monitoring holes, and make the microseismic sensors after installation
Effectively coupled with hole wall, be still the difficult point of current field monitoring and research, in particular for the multiple microseismic sensors of use to not
The deep monitoring holes of micro seismic monitoring are carried out with position, it is especially true.
