Abstract
The utility model discloses a tunnel gushing and mud bursting sudden geological disaster online monitoring and warning device, belonging to the technical field of tunnel geological disaster prediction. The device is composed of a monitoring apparatus consisting of a water turbidity sensor, a displacement sensor, a strain sensor and a water pressure sensor, a data acquisition memory consisting of a digital signal processor, a filter amplifier, an A/D conversion interface and a lower computer, as well as a control center consisting of a hub and an upper computer. Through the combination of four types of sensors, the warning device can timely monitor sufficient and reliable precursor information before the gushing and mud bursting geological disaster, and then give a directive warning after the data acquisition memory storage and the control center processing so as to realize the prediction of the tunnel gushing and mud bursting sudden geological disaster.
Description
Technical field
The utility model relates to a kind of by its precursor information kind that monitors and DATA DISTRIBUTION feature, the on-line monitoring prior-warning device that the water burst prominent sudden geology disaster of mud in tunnel is forecast.Belong to tunnel geology hazard forecasting technical field.
Background technology
The water burst prominent sudden geology disaster monitoring of mud prior-warning device in known tunnel mainly is made up of monitoring instrument, data collecting instrument, memory and control centre etc.Wherein, monitoring instrument is made of reinforcing bar flowmeter sensor, displacement transducer, pressure cell sensor.Sensor contacts with testee during work, and continuously the transfer of data that records is arrived data collecting instrument, is handled by control centre after memory stores.When having water burst to dash forward the mud omen in the tunnel, the data that various kinds of sensors collected just have ANOMALOUS VARIATIONS, and control centre just makes early warning after handling immediately, manually sounds the alarm.The less than one of this monitoring and warning device is variation in water pressure and the change of water quality of not considering in the tunnel, thereby usually other geological disaster etc. as the landslide class that is taken place in the tunnel is forecast as the prominent mud ground matter disaster of water burst in the lump, cause the subsequent processes measure wrong; The 2nd, after making warning, the control centre of the prominent sudden geology disaster monitoring of the mud prior-warning device of existing tunnel water burst needs artificial warning, and entire process process holding time is long, and emergency reaction speed is slow, misses the best opportunity of timely reply disaster.
The utility model content
In order to overcome the prominent sudden geology disaster monitoring of the mud prior-warning device deficiency that the forecast is inaccurate, reaction speed is slow of existing tunnel water burst, the utility model provides a kind of tunnel water burst sudden geology disaster of mud on-line monitoring prior-warning device of dashing forward, this device prominent sudden geology disaster of mud of water burst that can not only forecast with unerring accuracy, and can also judge exactly whether the tunnel caves in.
The formation that realizes the prominent sudden geology disaster of the mud on-line monitoring prior-warning device of tunnel water burst of the utility model purpose comprises monitoring instrument, the data acquisition memory, control centre and alarm, it is characterized in that the turbidity sensor of described monitoring instrument by monitoring water quality, the displacement transducer of monitoring wall rock loosening ring, the strain transducer of monitoring steel bow member stress and the hydraulic pressure sensor of monitoring boring water pressure constitute, described data acquisition memory is by the digital signal processor that is connected with above-mentioned each sensor, the filter amplifier that is connected with digital signal processor, the A/D translation interface that is connected with filter amplifier, the channel converter that is connected with the A/D translation interface constitutes with the slave computer that is connected with channel converter, and described control centre is made of with the host computer that is connected with hub the hub that is connected with slave computer
The utility model is by improving data acquisition unit and control centre, utilizes network to make this device become a centralized procurement collection, storage, transmission, report to the police and the real-time monitoring and warning device of automatic online of uninterrupted power supply automatically.By four kinds of sensors selecting to be provided with, can before taking place, the sudden geology disaster of the prominent mud of tunnel water burst monitor enough and reliable precursor information, comprising: quality of groundwater turbidity, wall rock loosening ring displacement, steel bow member stress and boring water pressure.Monitoring instrument is transferred to the data acquisition memory stores to these information that monitored, host computer in the control centre is downloaded data by hub from slave computer then, and these data are handled the back with professional treatment software and made comparison with predefined early warning standard in host computer.If quality of groundwater turbidity, wall rock loosening ring displacement, steel bow member stress and four kinds of information of boring water pressure have all surmounted standard value, just can judge that imminent geological disaster is prominent mud water burst geological disaster; Just be judged as the landslide geological disaster if having only wall rock loosening ring displacement and two kinds of information of steel bow member stress to surmount standard value.Control centre gives the alarm result of determination to the job site, corresponding counter-measure can be adopted according to the caution content of being forecast in the scene.
After adopting technique scheme, the utility model compared with prior art has following beneficial effect:
1, can distinguish the type of the sudden geology disaster in forecast tunnel effectively, for follow-up counter-measure provides foundation;
2, be swift in response, forecast in time;
3, real-time demonstration, transfer of data and the human-computer interaction function of utilizing host computer to have can realize at a distance the INTEGRATED SIGHT to quality of groundwater, wall rock loosening ring, steel bow member stress and the water pressure in tunnel.At suspicious section, management level can also help to improve the forecast level by means of the data acquiring frequency of Internet or GPRS network modification host computer.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the circuit working theory diagram of present embodiment
The specific embodiment
As shown in Figure 1, 2, monitoring instrument is made of the strain transducer 3 of the stress of the turbidity sensor 1 of monitoring water quality, the displacement transducer 2 of monitoring wall rock loosening ring 12, monitoring steel bow member 7 and the hydraulic pressure sensor 4 of monitoring water pressure; Wherein, the turbidity sensor 1 of monitoring water quality can be installed in the tunnel drainage ditch, the hydraulic pressure sensor 4 of monitoring water pressure is installed in 2/3rds highly borings 8 at place that are arranged in apart from the tunnel side wall bottom, and the installation site of all the other each sensors is the same with prior art.Described data acquisition memory 9 is made of with the slave computer that is connected with channel converter digital signal processor, the filter amplifier that is connected with digital signal processor, the A/D translation interface that is connected with filter amplifier, the channel converter that is connected with the A/D translation interface.Described control centre 11 is made of with the host computer that is connected with hub the hub that is connected with slave computer by network 10.Described turbidity sensor 1, displacement transducer 2, strain transducer 3 and hydraulic pressure sensor 4 are connected with digital signal processor alone respectively.Each part mentioned above all is equipped with uninterrupted power source, and above-mentioned each parts all can be selected existing commercial goods for use, and its connected mode and operating principle are existing known technology, no longer provides concrete circuit diagram here and gives unnecessary details one by one.
