Description

Electrolyte inclino-probe

This novel improvement that belongs to surveying instrument parts inclino-probe.

The pendulum model tiltmeter is used to measure the history of inclination and distortion existing three more than ten years of natural and artificial landslide and building foundation.During use the probe of this instrument is put in the plastics or aluminum sleeve pipe that are vertically installed in the soil body, the inclination and distortion of sleeve pipe is measured at probe different depth place in sleeve pipe, can learn the inclination and distortion situation of sleeve pipe through duplicate measurements, thereby reach the inclination and distortion situation of measuring the soil body.The shortcoming of this tiltmeter is because of sleeve pipe has certain rigidity, so the inclination and distortion of sleeve pipe can not be represented the inclination and distortion of the soil body fully really, probe is not an inclination and distortion of directly measuring the soil body, but realize measuring by sleeve pipe.When big, probe can't be put into sleeve pipe as the inclination and distortion of sleeve pipe, thereby measurement range is less, only can measure in the range of tilt angles in ± 12 °, and is very careful when using this probe measurement operation.The price of probe is very expensive.The cost of burying sleeve pipe underground also is sizable.

This novel purpose is to make a kind of novel dielectric solution formula inclino-probe at above-mentioned shortcoming, and the different depth place that surveys the soil body in desire imbeds this probe, can directly measure and react truly inclination and distortion situation in the soil body, enlarges measurement range.Reduce price.

These novel main points are, the dielectric solution formula inclino-probe that is provided is to utilize the variation that is contained in the dielectric solution in the container and is immersed in electrode submergence in the dielectric solution, makes and cause electric conductivity value to change.The electrode that is contained in dielectric solution in the container and several different azimuth is perpendicular to liquid level and be immersed among the dielectric solution, when the container run-off the straight, the submergence that is immersed in the several electrodes in the dielectric solution just changes, thereby electric conductivity value also just changes, container lean is to different angles, conductivity meter is measured the electric conductivity value with corresponding each electrode of each angle, calibrates the inclination calibration curve.Make when probe and to imbed in the soil body, because the electric conductivity value that inclination and distortion changes checks in corresponding angle of inclination and vergence direction in this in advance given probe inclination calibration curve.By at different time with to burying the measurement of different depth probe underground, can learn inclination and distortion situation in the soil body, also can calculate the changing value at angle of inclination between different survey time simultaneously.

This novel dielectric solution formula inclino-probe is directly imbedded desire and is surveyed different depth place in the soil body, can react inclination and distortion situation in the soil body truly, can measure ± inclinations in 45 ° of scopes, and its sensitivity can reach 2 '～8 '.This sonde configuration is simple, buries underground conveniently, and measuring operation is simple and reliable, and low price can be saved a large sum of expense of burying sleeve pipe underground.

Be described in further detail below with reference to the concrete structure of accompanying drawing invention:

As depicted in figs. 1 and 2, be encapsulated in the glass container (2) volume of the dielectric solution (3) in the volume of glass container (2) is greater than and is encapsulated in the potassium chloride dielectric solution (3) of certain volume with an end that can cut down inclined electrode (N.S.E.W) that bar makes, base stage (B), temperature compensating electrode (T).Make inclined electrode (N.S.E.W) be encapsulated in the interior end of container (2), and be partially immersed in the dielectric solution (3) perpendicular to liquid level.The end that base stage (B) and temperature compensating electrode (T) are encapsulated in the container (2) also all is immersed in the dielectric solution (3) perpendicular to liquid level.Six electrodes is encapsulated in the position distribution of container (2) shown in figure (2), and inclined electrode (N.S.E.W) is by north, south, east, an orientation, Xisi and quadrate, and base stage (B) is positioned at its central authorities.Temperature compensating electrode (T) is positioned at from base stage (B) has certain distance to get final product.The end that six electrodes is exposed is connected with six conductor cable (10) respectively, and power supply is led tester (11) and measured the usefulness that electricity is led.Packaged glass container (2) and connect the middle part that six conductor cable (10) is put into plastic casing (1) together, its bottom, top and middle gap are with inserts sandstone (4) and mineral tallow (5) filling and embedding.Plastic cover plate (6) snaps in from the top of shell (1), and from the lateral surface of shell (1) with screw (9) with it is fastening (at least three diverse locations with the fastening jail of this screw), on cover plate (6), fix one and collude the on-hook structure, promptly fix the angle bar (7) of a section (8) with holes, hole (8) should face toward the axis direction of inclined electrode (N.S), this hole is promptly orientable, can use for burying underground to collude to hang when popping one's head in again.Temperature compensating electrode (T) is used for proofreading and correct the influence of when difference variation is big in the soil body dielectric solution electricity being led, and can proofread and correct when difference variation is not more than 4 ℃.

The relation curve that the vergence direction of probe and angle of inclination and electric conductivity value change is at the experiment indoor standardization.The probe vergence direction and the electric conductivity value reading curve between angle of inclination and the same base stage of corresponding inclined electrode (N.S.E.W) (B) as shown in Figure 3 and Figure 4, each probe all provides NS and EW inclination calibration curve, calibration range is ± 45 °.The electric conductivity value reading of probe in the soil body is imbedded in measurement, just can check in the vergence direction and the angle of inclination of this probe from this given probe inclination calibration curve.According at different time with to imbedding the measurement of the probe of different depth in the soil body, just can learn the oblique situation of soil body introversion, and can calculate each survey inferior between the changing value at angle of inclination.
