Specific embodiment

Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality It applies example and attached drawing is cooperated to be explained in detail.

Embodiment one,

Referring to Fig. 1, the present embodiment provides a kind of for monitoring the device of crack expanding change, including displacement detector 10, signal projector 11, signal receiver 12 and reflector plate 13；The bottom of signal projector is arranged in the displacement detector On, reflector plate is provided with multiple, and multiple reflector plates are arranged at equal intervals on the two sides of rock mass Deep Fractures 14, signal projector For being embedded in the subsurface that can cover all reflector plates, signal receiver and signal projector are communicated to connect, signal transmitting Device covers all reflector plates for controlling signal, and the reflector plate is used to reflect the signal of signal projector transmitting, and signal connects Receive the signal that device is used to receive reflector plate.

Crack in the present embodiment and for monitoring can be the Rockmass fractures of dam Toppling Deformation, or in tunnel Crack.Signal projector can be frequency electromagnetic waves transmitter, and signal receiver is then high-frequency electromagnetic wave receiver.Carry out When monitoring the expanding change in crack, needs to install in advance and place reflector plate, signal projector and signal receiver.If in dam Under environment, tested point is manually chosen in each Rockmass fractures two sides of the Toppling Deformation of dam, which can split at one Sew on choose it is multiple, the case where in order to monitor crack variation, such as the real-time width of extension, length etc..Signal receiver It then needs to choose the position that can cover whole reflector plates, and is installed by way of being embedded in underground, led to simultaneously Cross whether displacement monitors monitoring signals receiver moves, in order to the position between calibration signal transmitter and each reflector plate Variation achievees the purpose that the expanding change of automatic monitoring Rockmass fractures to obtain the data of accurately Rockmass fractures variation.

Specifically, sending a signal to reflector plate using signal projector, each reflector plate reflects the signal, so that Signal receiver receives the signal of each reflector plate reflection, handles signal by the processing to the signal, such as using computer The signal of receiver feedback, the position data of available each reflector plate, such as the position data of reflector plate is made as three Dimension coordinate data is shown that the three-dimensional coordinate data of the reflector plate in a crack through multiple groups is positioned, therefore can To provide the real-time width and three-dimensional coordinate in the crack in real time, achieve the effect that automatic monitoring crack expanding change, for The variation in each crack can be carried out pre- pre-treatment.Improve the adaptability, durability and reliability of detection device, Ke Yiyou The geological condition complexity for solving the problems, such as crack location and/or bad environments of effect.

Embodiment two,

Referring to Fig. 2, the present embodiment also provides a kind of system for monitoring crack expanding change, including monitoring device 1 With controlling terminal 2, the monitoring device is the device for being used to monitor crack expanding change of embodiment one among the above；The monitoring The signal receiver and controlling terminal of device communicate to connect.The controlling terminal is laptop, tablet computer or mobile phone.

Rockmass fractures or tunnel slot are monitored using monitoring device in the present embodiment, and by the data feedback of monitoring To controlling terminal, that is, feed back in laptop, and signal receiver may be mounted on laptop, or install outside It sets, then is communicatively coupled with laptop, therefore the information of signal receiver feedback can be handled by laptop. Specifically, choosing tested point on needing monitored crack, and reflection is installed on the tested point that the two sides in the crack are chosen Piece, and then the fixed point that can cover all reflector plates, the embedding signal on the fixed point are chosen in the area for needing to be detected Transmitter, therefore all reflector plates can be covered, the position in crack is determined by the telecommunications that reflector plate reflects, displacement monitors exist The bottom of signal projector changes for monitoring signals emitter position, corrects Crack Monitoring data.Therefore with the change in crack Change the movement for generating bottom surface, and then obtains multi-group data and the situation of change in crack is obtained, i.e., by the analysis and processing of data The signal reflected via reflector plate can be received by signal receiver, and simultaneously by signal Wireless transceiver to controlling terminal；Control Terminal converts the signal into displacement data, to provide the real-time width and three-dimensional coordinate in each crack.Automatic monitoring is reached The effect of crack expanding change, while full automatic monitoring is carried out by embedding method, improve monitoring device adaptability, Durability and reliability, can and/or bad environments complicated with the geological condition of effective solution crack location the problem of.

The setting of monitoring device described in the present embodiment is there are three more than.Can simultaneously using multiple monitoring devices to topple over become The crack of shape is monitored, therefore can expand the coverage area of monitoring, while also having been reached while having been monitored a plurality of crack Effect improves the adaptability for monitoring the system of crack expanding change.

It should be noted that being not intended to limit although the various embodiments described above have been described herein The scope of patent protection of the utility model.Therefore, based on the innovative idea of the utility model, embodiment described herein is carried out Change and modification or equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly Or above technical scheme is used in other related technical areas indirectly, it is included in the protection model of the utility model patent Within enclosing.
