Background technology
At present in fields such as foundation pit construction, Safety of Tailings Dam monitorings, the soil body, dam body change in displacement be an important monitoring object, wherein it is divided into external displacement and internal displacement, external displacement can be passed through the method such as GPS, total powerstation and realize measuring, and internal displacement measures mainly through rod-type inclinometer.Ultimate principle is: the length of rod-type inclinometer is fixed, and by the change at angle of inclination, by relation calculated level displacement L=Len*Sin (α) of trigonometric function, wherein Len is the length of rod-type inclinometer, and α is angle of inclination.
Traditional method utilizes obliquity sensor to measure the change of pitch angle value of vertical direction, change in displacement by the level that calculates of trigonometric function, further according to the degree of depth of actual object of measurement, lay the sensor of respective numbers, thus obtaining the overall trend of internal blas under vertical direction.
Above-mentioned traditional monitoring system realizes there is following deficiency:
Tradition inclinometer is when measuring the tested soil body, because of the restriction of cost and sensor own dimensions, and limited amount of layouting, cause cannot the deformation of whole pipeline being measured.During conventional laying, 4～5 measuring points often only measured by a pipeline, then, judge internal displacement situation by the trendgram of 4～5 points, there is certain uncertainty.
Being made up of a mechanical cantilever inside tradition inclinometer, according to acceleration of gravity directional characteristic, the angle of cantilever reflects the change at inclination angle.Therefore the structure by mechanical cantilever is limit, and this type of inclinometer impact resistance is poor, all needs to protect when transport, installation, once there is impact injury, namely sensor cannot be repaired, and causes that use cost, reliability affect to some extent.
In sum, traditional inclinometer has some limitations in cost control, resistance to mechanical impact, high and low temperature environment etc., it is difficult to meet the requirement under current working.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of condenser type soil deformation and measures sensor.
