The purpose is in the construction process building, structures on drawing etc. plan-position and elevation, project on ground, make
For the foundation of engineering construction, through in entire work progress.The success or not of measurement work is directly determined and is affected entirely
The success or failure of engineering construction.The datum mark of measurement provides the master reference point coordinate of measurement for the preceding construction unit that constructs.And it is at present
Only, the whether wrong method of master reference point that review construction unit provides is that master reference point measures closure, but this
Method can only check master reference point relative tertiary location accuracy, cannot check the accurate of the coordinate system of master reference point composition
Property.
Summary of the invention
That It is an object of the present invention to solve the deficiency of the existing technology and provide a kind of measurement methods is simple, accuracy rate is high
Construction survey master reference point coordinate system checks method.
The purpose of the present invention is achieved through the following technical solutions:
A kind of construction survey master reference point coordinate system review method, comprising the following steps:
(1) the selection review date: the night that selection is fine, stars are bright carries out construction survey master reference point coordinate
System's review；
(2) instrument sets up and builds a station:
A. the master reference point for selecting the relatively positive northern visual field more open is survey station point, and total station instrument is erected at survey
After website, multi-angle rotary total station adjusts the level and accuracy of alignment of instrument；
B. another master reference point for selecting construction unit to provide is backsight point 1, and prism is erected at backsight point 1 and is guaranteed
Prism sets up vertical；
C. total station is opened, three-dimensional coordinate (X, Y, H) and instrument height, the prism for inputting survey station point are high, and backsight point 1 is three-dimensional
Coordinate (X1,Y1,H1), collimation axis is aimed at into 1 prism centers time point "Yes" of backsight point, confirmation is completed to build a station；
D. measurement of coordinates function is used in total station, the master reference point provided backsight point 1 and other construction units
The coordinate of backsight point 2 is checked, and error, with regard to point " OK ", otherwise searches reason until adjusting within 3 millimeters；
(3) Polaris is positioned:
A. Polaris position is found, is directed at Polaris with total station sighting device；
B. cellphone GPS function is opened, then the longitude and latitude of site location is surveyed in inquiry, and the total station elevation angle is then adjusted to 90
Degree subtracts the degree that the latitude in the place obtains, and the total station elevation angle is locked；
C. azimuth and the focal length for adjusting total station, find Polaris；
D. azimuth, the elevation angle and the focal length for finely tuning total station, make eyepiece " ten " word silk be directed at Polaris center；
E. according to survey station point coordinate, the survey station point convergence of meridians is calculated；
F. the azimuth angle of total station at this time is checked, if azimuth angle and calculated gisement angle error exist
3 " with regard to point " OK " in, otherwise need repeatedly to test review, if error is consistently greater than 3 ", the original of construction unit's offer is provided
Datum mark coordinate is wrong, must be reported to construction unit.
The present invention provides a kind of construction survey master reference point coordinate systems to check method, is avoided from the root because of construction
The construction survey master reference point that unit passes through occurs measuring quality problems caused by error.Measurement method of the present invention is simple, real
With being built suitable for room, the construction survey in highway, railway, tunnel etc..
The present invention will be further described below with reference to the drawings.
