Description
Technical field
The present invention relates to underground deep disaster monitoring device.
Background technology
The earth's surface deformation of the safety monitoring of geological hazard body mainly monitoring disaster body and underground deep deformation, when disaster body
When deforming, being first under ground portion deformation, reflection is to earth's surface then, the soil body of the following different depth in earth's surface (or rock mass, soil
Rock mixture) deformation can the deformation tendency of direct reaction disaster body, therefore, carry out this monitoring to the prediction of disaster, pre-
Anti-very helpful.
The instrument being presently used for measuring underground deep deformation is mainly manual type inclinometer, and its measuring method is to utilize in advance
First it is installed on the inclinometer pipe with vertical rail in the boring of disaster body, periodically deviational survey bar is put into along track, at different depth
Stop measurement gradient, and then calculated what the displacement of different layers position, this instrument or method existed by degree of depth integrating meter
Problem mainly have following some: 1, measure cycle length, automaticity low.Periodically arrive monitoring click on owing to needing technician
Row manual operation, record, it is impossible to accomplish the intensive collection of Monitoring Data, Monitoring Data can compare after needing to input computer
To analysis, monitoring efficiency is the lowest；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, can only drilling again, cause monitoring expense to increase and Monitoring Data discontinuous；3, measurement data
Error is big.When monitoring boring is deeper (general drilling depth is at 30～50 meters), test tube can rotate deformation, in test tube
Track reverses therewith, and the orientation that the torsion of track can directly result in the measurement of deviational survey bar changes, and produces measurement result straight
Connect impact (such as: what deviational survey bar was measured when earth's surface is to slide to vertical direction with disaster body, along with increase, the windup-degree of the degree of depth
Becoming big, possible deepest point track has created the windup-degree of tens degree, causes measurement deflection error).
In recent years, also occur in that some can all automatic measurement underground deep deformation device, such as stay-supported deep displacement
Measurement apparatus, full-automatic inclination measurement device.
Stay-supported deep displacement measurement apparatus: the survey line that some can be freely movable is caused underground different depth from earth's surface
Fixing, when after disaster body slide strips through generation block alternate displacement, survey line being elongated, changed by the bracing wire length measuring earth's surface
Obtaining disaster body sliding deformation, this method is insensitive to the inclination and distortion of disaster body early stage, can only measure side slope slide strips through
After big displacement, generally this stage is the most extremely dangerous, and possible Field Force has little time to withdraw.
Full-automatic inclination measurement device: some obliquity sensors are installed on following different layers position, earth's surface, measures each sensing in real time
The tilt data of device, this method exists that measurement amount is single, obliquity sensor once lost efficacy the shortcoming that cannot change.
Therefore, all there is single the asking of measurement amount in stay-supported deep displacement measurement apparatus and full-automatic inclination measurement device
Topic, meanwhile, there is also poor sensitivity and the problem that can not change sensing element respectively.
Summary of the invention
The inefficacy low, easy of exist for present technology or automaticity, error of measured data are big, or measurement amount is single,
Poor sensitivity, the problem of sensing element can not be changed, the present invention provide a kind of physical quantities full-automatic, many, be difficult to lose efficacy, spirit
