Summary of the invention
The objective of the invention is, a kind of impending earthquake alarm device is provided, it can continuous acquisition than the terrestrial stress of rock stratum, depths, physical quantitys such as gentle displacement, according to the variation of these physical quantitys, can judge whether earthquake is about to take place.
Technical scheme of the present invention is, impending earthquake alarm device is arranged in seismic zone by vertical insertion but does not have the inserting tube 1 of rock stratum of seismic activity temporarily and the signal cabin 2 of inserting tube 1 top is formed, it is characterized in that, inserting tube 1 is a long metal pipe, the bottom tube wall of inserting tube 1 is every a segment distance, just have four apertures 3 along garden Zhou Fangxiang, angular distance between the aperture 3 is 90 °, pressure transducer 4 is installed in the aperture 3, pressure transducer 4 all has the communication link 6 in signal transmssion line 5 and the signal cabin 2 to be connected, inserting tube 1 bottom and middle part inwall are equipped with temperature sensor 7, temperature sensor 7 is connected with communication link 6 through signal transmssion line 8, the upper end of inserting tube 1 is equipped with displacement transducer 9, displacement transducer 9 is connected with communication link 6 through signal transmssion line 10, and inserting tube 1 inwall is equipped with and is used for fixing signal transmssion line 5,8 ply-yarn drill 11.
Below using method of the present invention and principle of work are done detailed explanation.
At first position of the present invention is installed and is a bit larger tham inserting tube 1 external diameter with the vertical diameter that bores of rig in plan, the hole, garden of the about 1-2km of hole depth after drill bit puts in place, is carried before the brill, soft topsoil and shallow-layer broken rock carries out grouting treatment around the hole, reply garden, in order to avoid hole wall collapse.After hole, garden typing, with the boring tower of this rig with inserting tube 1 together with pressure transducer 4, temperature sensor 7 is put into by joint, bottom the through hole, garden, inserting tube 1 top exceeds the about 1m of terrace, inserting tube 1 is promptly buried underground and is finished.Build up signal cabin 2 then, at installation position, the top displacement sensor 9 that is higher than terrace of inserting tube 1, and signal transmssion line 5,8,10 is connected with communication link 6, the present invention promptly installs.
Take place the most frequently, the also maximum tectonic earthquake of destructive power is that the accumulation of terrestrial stress or strain energy causes.In the imminent earthquake stage, the terrestrial stress size is near the maximum intensity of focus rock, be in the critical conditions that extensive fracture will occur, this moment is because the change of focal area physics, chemical state, just many earthquake precursors phenomenons can and take place in the neighbourhood in the epicentral area in future, change as terrestrial stress, geothermal anomaly, the landform variation is normal, geomagnetic anomaly, gravity anomaly, ground water anomaly, wave speed of the earthquake is unusual etc., and the present invention often sends imminent earthquake according to the terrestrial stress variation that is not subject to the external factor interference, geothermal anomaly and landform variation to report to the police.
When the present invention installed, this place did not have seismic activity, so pressure transducer 4, the numerical value that displacement transducer 9 shows is 0, and what temperature sensor 7 recorded also is a constant regime values.If future certain constantly this place or near underground formation focal area and be about to take place earthquake, as previously mentioned, terrestrial stress to occur changes and the geothermal anomaly phenomenon, since these abnormal occurrencies are caused by the focal area, therefore the variation of terrestrial stress and ground temperature must begin from the focal area or upwards expand gradually soon or slowly, when the variation of terrestrial stress expanded to the bottom of inserting tube l, the rock at this place was squeezed, and the size and Orientation of extruding force can be detected by pressure transducer 4; Mechanical energy part during extruding converts heat energy to, so the temperature of rock stratum has also raise, the phenomenon that temperature raises also can be detected by temperature sensor 7, the data of terrestrial stress and ground temperature rise upload to competent authorities through communication link 6, be imminent earthquake early stage this moment, and liftoff shake takes place to also have a couple of days or a few hours.
Along with the continuation variation of terrestrial stress, inserting tube 1 also is squeezed than the rock at place, top, and the pressure transducer 4 at this place detects pressure to be increased, and temperature sensor 7 also detects ground temperature and raising, and be imminent earthquake mid-term this moment, and liftoff shake generation is very near.
Because terrestrial stress is upwards expansion constantly, causes inserting tube 1 torsional deformation and displacement, variation has also taken place in ground surface or terrain, these distortion and variation can both be detected by displacement transducer 9, and in time upload to competent authorities through communication link 6, and be the imminent earthquake later stage this moment, earthquake is about to generation.
Earthquake its ferment and the process that forms in, also can cause the variation of location chemical property of the earth, these variations can detect from the gas that rises to inserting tube 1 bottom the signal cabin 2 through inserting tube 1, therefore, in the signal cabin 2 gas analysis equipment can also be installed, to assist to judge whether to be about to take place earthquake.
As mentioned above, the present invention can carry out imminent earthquake to the essential earthquake and report to the police, but can not report to the police to artificial earthquake or the seismic event that transmits at a distance, though this is because the seismic event that artificial earthquake or distant place are transmitted also can cause inserting tube 1 variation of stress peripherally, but this version is the terrestrial stress fast rising, decay rapidly again is easy to differentiate.
At a seismic zone, every a segment distance, as tens of kilometers or kilometer up to a hundred, one cover apparatus of the present invention should be installed and connect into net, like this according to the size and Orientation of everywhere the detected synchronization terrestrial stress of apparatus of the present invention, with the height of ground temperature, can judge the position in earthquake centre in the future, also may rule of thumb estimate the intensity of the earthquake that will take place.
The degree of depth that inserting tube 1 is buried underground should not be too dark, this is because behind certain depth on the one hand, the boring cost will be the index multiple along with the increase of the degree of depth and rise, be because the lithosphere mechanical property of deep layer is inhomogeneous on the other hand, therefore plate movement also has certain randomness, near the variation of detected terrestrial stress and ground temperature and do not mean that this place or earthquake will take place.After comprehensive the comparison, the depth of burying of inserting tube 1 is advisable with 1-2km.
In sum, advantage of the present invention is:
1, can when imminent earthquake, in time find terrestrial stress, variations such as gentle displacement, for the shock-absorbing mitigation gains time.
2, the present invention changes according to the terrestrial stress that is not subject to the external factor interference, geothermal anomaly, landform variation work often, so reliability is higher.
