The authenticity of the testee displacement measured.GNSS, can directly to survey area's GNSS reference station as fixed point as not being subjected to displacement
Carry out corresponding displacement measurement；In case of displacement, by being repaiied with country or local base station translocation data numeral in line shift-in row
Just, using revised survey area GNSS reference station coordinate as fixed point, then reception satellite-signal synchronous with measuring point and difference is carried out
Processing, with the coordinate of the measuring point after being corrected, to learn whether measuring point is subjected to displacement.Currently, GNSS observations are not required to intervisibility
And can carry out with country or local base station translocation, so many engineerings use this monitoring means, but with country or place
Whether base station translocation is met the requirements by many limitations, such as the frequency of national or place base station data acquisition, translocations.
Utility model content

String holes, reversed pendulum protection pipe, anchor, buoyant device and holder；GNSS reference station be arranged on the basis of one, on the basis of set
It is equipped with calibration device pier；Reversed pendulum hole is extended to by calibration device pier surface in the stabilization basement rock of underground, and holder is arranged in calibration
On device pier and corresponding with reversed pendulum hole site, buoyant device is connect with holder, and reversed pendulum protection pipe is embedded in reversed pendulum hole, hangs down
Line is located in reversed pendulum protection pipe, and reversed pendulum lower end is by anchor and stablizes basement rock anchoring, and reversed pendulum upper end is filled with buoyancy
The floating body connection set, the buoyancy of buoyant device make reversed pendulum be in tensioned state always.
It is further：Reversed pendulum is located at the center of reversed pendulum protection pipe.
The utility model has the beneficial effects that：1 verifies GNSS reference station horizontal position using the reversed pendulum method of the utility model
GNSS reference station position correction is moved and carries out accordingly, reversed pendulum observation is convenient, precision is high, periodic observation reversed pendulum knows start of calculation
The opposite variation of basic point, can eliminate influence of the surface meteorologic factor to GNSS reference station, ensure stablizing relatively for GNSS reference station
Property, improve hydroelectric project safety monitoring accuracy.
2 overcome GNSS reference station and country or the frequency problem of local base station translocation, and reversed pendulum observation can meet not
Same time, various forms of translocations requirement, operation are more feasible, more convenient.
3 degree of falling vertical depth are determined regarding geological condition, can measure the changing value relative to deep anchor block point, point corrects precision can
Up to 0.2mm, precision is higher.
4GNSS reference stations can reduce and national or local base station translocation, overcome the shortcomings that data are difficult to obtain.
