Description

Spring acoustic emission sensor erecting device
Technical field
Rock (body) project security monitoring technical field that the utility model belongs in engineering construction, is related to a kind of spring Acoustic emission sensor erecting device.
Background technology
Mine rock (body) deformation failure in engineering construction, particularly rock burst dynamic disaster, can directly jeopardize engineering Security Construction, or even devastating impact can be caused, therefore rock (body) stability and rock burst dynamic disaster are effectively monitored And forecast, it is one of important content of engineering safety construction.At present, a kind of important means of the sound emission as non-destructive monitoring, quilt For rock (body) stability in engineering construction and the monitoring and forecast of rock burst dynamic disaster.
In underground engineering wall rock excavates process of construction, in order to enter to the failure and deformation of surrounding rocks being likely to occur and dynamic disaster Row Accurate Prediction, acoustic emission sensor needs are arranged in monitored in the form of three-dimensional spatial distribution in advance before engineering excavation Country rock region, and the number of sensors arranged is more, and monitoring effect is relatively more accurate.
In specific implementation, it is necessary to before rock (body) excavation, drilled using rig in stone (body), drilling depth Increase with engineering buried depth, monitored scope increase;But drilling is deeper, acoustic emission sensor installation is more difficult.At present, sound is sent out Sensor mounting means is penetrated mainly including following several:
(1) in engineering site, directly acoustic emission probe is put in the borehole, by the liquid medium remained in drilling (such as Water) medium that is transmitted as signal between rock mass and acoustic emission probe, the detectable signal received passes through line by acoustic emission probe Cable is transferred to ground monitoring system;But there is following drawback in this method:It is downward that 1. this implementation is appropriate only for direction Drilling, and for the fully horizontal or upward drilling for having certain angle, do not applied to due to being difficult to medium for storing;Even for Under drilling, it is still necessary to the rock mass for the surrounding that drills is relatively complete, so as to avoid transmission medium from borehole fissure be lost in or ooze out, really Acoustic emission probe is protected to be in transmission medium all the time, but on-site actual situations are but relatively inaccessible to the requirement, so as to influence to monitor Effect;Although 2. the couplant that the liquid between rock mass and acoustic emission probe can transmit as signal, the density of liquid General relatively low, its signal transmission effect with palisades not as effectively contacting received detection letter directly by acoustic emission probe Number.
(2) in order to ensure placing efficient coupling between acoustic emission probe and the wall of a borehole in the borehole, may be used also in engineering site Using the casting cement into drilling, acoustic emission probe and palisades are made to be cast for an entirety, although this method can solve Effective transmission problem of detectable signal, but still suffer from following defect:1. the acoustic emission probe after cast is not recyclable, cause to monitor Cost is too high;If 2. finding acoustic emission probe no signal or poor signal after cast, it can not be checked or be adjusted, can only be again New acoustic emission probe is drilled and installs, it is too high not only result in monitoring cost, and also results in extension project progress, or even delay Duration;3. injecting cement mortar into drilling, deeper because drilling, the slip casting effect of one side acoustic emission probe installation position is difficult to protect Barrier, it is possible that acoustic emission probe installation position fails the situation of effective slip casting, so as to cause acoustic emission probe not with palisades Efficient coupling and without monitoring signals;On the other hand drilling is deeper, and total contraction distortion amount after the theing cement solidifies of cast is bigger, with water The signal transmission cable for the acoustic emission probe that mud bonds together can bear pulling force because cement shrinkage deforms, and causing can not be effective Transmission signal;4. the explosive in digging process is blown out, slip casting face may be made to be relaxed with rock wall surface, cause what monitoring signals were transmitted Validity reduces;5. generally moister in drilling, cement slurry sets need longer cycle after cast, and the construction time limit can be caused to prolong It is long;And installation process is time-consuming, laborious, it is necessary to a series of professional grouting equipments and slip casting personnel, so as to further increase monitoring into This.
(3) another kind is achieved in that using simple secure mounting arrangements, acoustic emission probe is fixed on inside device, so After fixing device is delivered into installation position with rigid non-movable metallic transmission bar afterwards, acoustic emission probe is ejected with pressure Contacted afterwards with drilling palisades, realize and fix, its advantage is to realize connecing for acoustic emission probe and palisades in the case of non-slip casting cast Touch, but still have the following disadvantages:1. this mode needs because secure mounting arrangements and the distance between borehole wall are close Want secure mounting arrangements to be essentially concentric structure with drilling, and need hole wall smooth, but these requirements are difficult to protect in practice of construction Barrier;2. because secure mounting arrangements size is larger, the drilling being relatively large in diameter is only applicable to, causes the cost rise that drills;It is 3. whole Transmission pole and erecting device are to be inserted into by hardness of exerting oneself in drilling in the borehole, and not only frictional force is big, cable of easily grinding away Or acoustic emission probe, it is also easy to be snapped in drilling, can not deliver to needs position to be mounted;4. due to being by secure mounting arrangements By external force, during its hardness insertion is drilled, therefore installation process not only wastes time and energy, and operating efficiency is extremely low;5. because boring Hole hole wall is cylindrical surface, and acoustic emission probe end face is plane, how to ensure acoustic emission probe end face effectively and borehole wall Coupling, and the problem solved is needed in practical application.
Based on drawback and defect present in above-mentioned various implementations, cause acoustic emission detection in rock (body) stability And by a definite limitation during the application of rock burst dynamic disaster monitoring.
Thus, it is how convenient, effectively by acoustic emission probe installation in the borehole, and have the acoustic emission probe after installation Effect couples with hole wall, is still the difficult point of current field monitoring and research, lacks relevant test method and technical support.
