Description
Technical field
The present invention relates to underground deep disaster monitoring device.
Background technology
The safety monitoring of geologic hazard body is mainly earth's surface distortion and the underground deep distortion of monitoring disaster body, when disaster body deforms, first be under ground portion distortion, then be reflected to earth's surface, the deformation tendency of disaster body can be directly reacted in the distortion of the soil body of the following different depth in earth's surface (or rock mass, soil-rock mixture), therefore, carry out this monitoring to the prediction of disaster, prevent very helpful.
At present, for measuring the instrument of underground deep distortion, it is mainly hand tiltmeter, its measuring method is to utilize the inclinometer pipe with vertical rail being installed in advance in the boring of disaster body, regularly deviational survey bar is put into along track, in the different depth measurement degree of tilt of stopping, and then by degree of depth integrating meter, calculate the displacement of different layers position, the problem that this instrument or method exist mainly contain following some: 1, measuring period is long, automaticity is low.Because needs have technician regularly to arrive monitoring point, carry out manual operation, record, can not accomplish the intensive collection of Monitoring Data, Monitoring Data can compare after need to inputting computing machine, and monitoring efficiency is comparatively low; 2, easily lost efficacy.After undergoing mutation in certain layer of position of disaster body, test tube generation crimp, deviational survey bar just can not pass through, and drilling, causes the discontinuous of the increase of monitoring expense and Monitoring Data again; 3, error of measured data is large.When monitoring boring is darker (general drilling depth is at 30～50 meters), test tube can rotate distortion, track in test tube reverses thereupon, and the orientation that the torsion of track can directly cause deviational survey bar to be measured changes, measurement result is had a direct impact to (as: what deviational survey bar was measured when the earth's surface is to slide to vertical direction with disaster body, along with increase, the windup-degree change of the degree of depth are large, possible deepest point track has produced the windup-degrees of tens degree, causes direction of measurement error).
In recent years, also there is the device that some can the distortion of all automatic measurement underground deep, as stay-supported deep displacement measurement mechanism, full-automatic inclination measurement device.
Stay-supported deep displacement measurement mechanism: by some can be freely movable survey line from earth's surface, cause underground different depth and fix, after the sliding band of disaster body connects generation block alternate displacement, survey line is elongated, by measuring the bracing wire length variations on earth's surface, obtain disaster body sliding deformation, this method is insensitive to the inclination and distortion in disaster body early stage, can only measure the large displacement after the sliding band of side slope connects, common this stage is very dangerous, and possible field staff has little time to withdraw.
Full-automatic inclination measurement device: some obliquity sensors are installed on to following different layers position, earth's surface, measure in real time the tilt data of each sensor, the shortcoming that measuring amount is single once this method exists, obliquity sensor lost efficacy and cannot change.
Therefore stay-supported deep displacement measurement mechanism and full-automatic inclination measurement device all exist the problem that measuring amount is single, meanwhile, also there is respectively poor sensitivity and the problem that can not change sensing element.
Summary of the invention
