Embodiment

[0016] Such as figure 1 As shown, the detection system of the present invention has the tunnel section monitoring function. The microseismic sensor is used to collect the stratum information in the tunnel through real-time vibration. A microseismic sensor transmits the collected data to the acquisition instrument, and the acquisition instrument judges the waveform generated by the feedback information collected after the microseismic sensor vibrates, analyzes the position and change trend of the aquifer in the strata in the tunnel, and obtains Real-time data processing is performed on the position information and change trend of the aquifer, and the redundancy is removed through filtering to obtain effective data processing results. The effective data processing results include: the position, time, energy and corresponding feedback of formation vibration information corresponding to microseismic events. shock wave transmission speed. According to the vibration echo data of th...

Abstract

The invention discloses a detection system with a tunnel section monitoring function. The microseismic sensor performs real-time vibration to collect the ground layer information in the tunnel. A plurality of microseismic sensors is horizontally disposed 20 centimeters above the ground on the inner surface of the tunnel. Each microseismic sensor transmits the collected data to a collecting instrument, and according to the waveform generated through feedback information collected by the microseismic sensor after the vibration, the collecting instrument judges the waveform, analyzes the positionand the changing trend of the aquifer in the stratum in the tunnel, and processes the real-time data of the obtained aquifer position information and change trend. The redundancy is removed by filtering to obtain effective data processing results. The effective data processing result includes ground layer vibration information of location, time, energy and corresponding vibration wave transmission speed that corresponding to the feedback generated by micro-vibration events.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a detection system with tunnel section monitoring function. Background technique [0002] Tunnels are often excavated in mines, coal mining, water conservancy, railway and road construction. The gas content in the tunnel and the geological conditions of the mining area are related to the personal safety of the construction personnel and the progress of the construction, so the monitoring of the tunnel condition has become an important technical issue in the tunnel construction. [0003] The existing tunnel monitoring method is to use the method of advanced drilling to monitor the geological conditions, that is, to drill holes on the face of the tunnel that has been excavated, and to check whether the drilled ballast in the drilled hole or whether liquid and liquid flow out of the drilled hole. This method is not only time-consuming and inefficient, but also the detection distance is limite...
