A kind of ultra-wide waters Precision River-Crossing Leveling device provided by the utility model has and synchronizes directly opposite see
It surveys, directly measure the feature that instrument is high and surveyor's beacon is high, effectively reduce the influence of Atmosphere Refraction and earth curvature, significantly reduce
Measurement error, measurement method the following steps are included:
S1, forced centering pier A, B are set in the side on riverbank, the other side is arranged forced centering pier C, D, four are coaxially observed
Mark branch seat frame is separately mounted on forced centering pier A, B, C, D；
S2, the spiral adjustment component adjusted on upper base plate level coaxial surveyor's beacon branch seat frame, use vernier by pipe spirit level
Stock rod precision measures the vertical distance of coaxial surveyor's beacon support arch to the convex crown of forced centering pier, is coaxially observed according to known
The height for marking the height of branch seat frame and the height of total station and surveyor's beacon lamp, calculates separately and obtains the high i of total station and the high v of surveyor's beacon；
S3, coaxial surveyor's beacon branch seat frame on forced centering pier A, C pedestal on dispose total station, then in coaxial surveyor's beacon
Support arch installs surveyor's beacon lamp, and two total stations, to the same direct bilateral observation of light section, measure vertical angle α in the same periodAC
And αCA；
S4, forced centering DunAChu total station remain stationary, the total station and surveyor's beacon lamp of forced centering DunCChu moves together
Forced centering DunDChu is moved, two total stations, to the same direct bilateral observation of light section, measure vertical angle α in the same periodADWith
αDA；
S5, forced centering DunDChu total station remain stationary, the total station and surveyor's beacon lamp of forced centering DunAChu moves together
It moves at B, 2 total stations synchronize mutual bilateral observation, measure vertical angle αBDAnd αDB；
S6, forced centering DunBChu total station remain stationary, the total station and surveyor's beacon lamp of forced centering DunDChu moves together
Forced centering DunCChu is moved, 2 total stations synchronize mutual bilateral observation, measure vertical angle αBCAnd αCB, so far complete vertical angle
Upper semiobservation observation；
S7,2 total station positions for being located at two sides are exchanged, and coaxial surveyor's beacon branch seat frame and surveyor's beacon lamp are motionless, press more than
Step is completed semiobservation under vertical angle and is observed；
S8, two total stations are successively separately mounted to A, B and C, on D forced centering pier, the corresponding placement of two prism groups
The top of coaxial surveyor's beacon branch seat frame on C, D and A, B forced centering pier, measurement, calculate between two sides forced centering pier it is flat away from
D；
S9, according to the flat vertical angle α away from D and corresponding total station to surveyor's beacon lamp between forced centering pier, and it is corresponding
The high i of instrument and the high v of surveyor's beacon, calculate two sides forced centering pier between toward survey height difference average value, as elevation aberration measurements
α includes αACAnd αCA, i includes iAAnd iC, v includes vAAnd vC；
Elevation aberration measurements between other forced centering piers of two sides are calculated according to above formula；
S10, it is observed, is measured with two, bank back and forth by ad eundem measurement of the level required precision using leveling measuring method
The height difference h of forced centering pier A, B and C, DAB waterAnd hCD water.Then compensating computation obtains the elevation of each forced centering pier, completes cross a river
The measurement of the level.
In the above scheme, in step s 2, the high i of instrument and the high v calculation formula of surveyor's beacon are as follows:
I=LInstrument+(L-LFrame)
V=LIt observes+L
L is the vertical distance that coaxial surveyor's beacon support arch connects bolt top to forced centering pier, L in above formulaFrameIt is coaxial
Surveyor's beacon branch seat frame oneself height, i.e., the vertical distance of seat of honour plate top surface of the coaxial surveyor's beacon branch seat frame Roof face to its pedestal, LInstrument
For total station oneself height, the i.e. height at total station horizontal axis center to its bottom, LIt observesFor surveyor's beacon lamp oneself height, i.e., in surveyor's beacon lamp
The heart is to the distance of its low side, and surveyor's beacon lamp center is to coaxial surveyor's beacon branch after being installed in coaxial surveyor's beacon branch seat frame equal to surveyor's beacon lamp
The distance of seat frame top plate top surface.
In above-mentioned steps S9, the height difference calculation formula between the forced centering pier of two sides is as follows:
According to bilateral observation trigonometric levelling principle, the elevation aberration measurements between forced centering pier A, C of two sides are calculated:
The environment and observation condition for passing through sight because of the utility model are very much like, it is believed that from A to C observe and from
Atmospheric Refraction Coefficient k when C is observed to AACAnd kCAIt is equal, the round-trip horizontal distance D of bilateral observation between A, CACAnd DCAAlso phase
Deng so having:
Therefore between forced centering pier A, the C of calculating two sides for carrying out river-crossing leveling using coaxial surveyor's beacon support frame apparatus
Elevation aberration measurements formula can simplify are as follows:
Elevation aberration measurements between other forced centering piers of two sides are calculated according to above formula.
Compared with prior art, the utility model has and synchronizes direct bilateral observation, directly measures instrument height and surveyor's beacon height
The characteristics of, it has been obviously reduced in trigonometric levelling by Atmosphere Refraction, earth curvature, the high error of amount that instrument is high and surveyor's beacon is high
Equal adverse effects, precision and work when substantially increasing to ultra-wide waters using trigonometric levelling progress river-crossing leveling
Efficiency.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn that the enlightenments in the utility model
Under the structure change made, it is all that there is same or similar technical solution with the utility model, each fall within the utility model
Within protection scope.
