Mark transmission method, including the first total powerstation and the second total powerstation, sets up the first total powerstation, silo bottom in the upper flat section of vertical shaft
Set up the second total powerstation, be incident upon the laser point coordinates of upper curved section by the first total powerstation detection, the second total powerstation is set, it is achieved
Coordinate transmits.
Preferably in scheme, comprise the following steps:
1) in the upper flat section and bottom of vertical shaft, the first total powerstation and the second total powerstation are set up respectively；
2) utilize the second total powerstation of silo bottom by laser projections A point on upper curved section, then utilize and arrange in upper flat section
First total powerstation projection laser, make the laser projections of the first total powerstation on A point, obtain A point coordinates value；
3) utilize the second total powerstation of silo bottom by laser projections B point on upper curved section, then utilize and arrange in upper flat section
First total powerstation projection laser, make the laser projections of the first total powerstation on B point, obtain B point coordinates value；
4) according to step A, B two point coordinates, utilize what Freedom Station carried out the second total powerstation to set station；
5) the first total powerstation and the second total powerstation project simultaneously laser to upper curved section same point C, by the first total powerstation and second
The C point coordinates that total powerstation records is compared, and controls in error allowed band, completes coordinate transmission；
6) utilize Casio computer program to carry out the excavation contour line setting-out of vertical shaft, out break inspection, section survey, complete down
Turning to of curved segment determines.
Preferably in scheme, the first described total powerstation and the second total powerstation use diagonal eyepiece, and simultaneously at upper curved section
On three reflector plates are set.
Preferably in scheme, the dowel of described shaft wall welds three block plates, paste immediately below steel plate and arrange instead
Penetrate sheet, after completing coordinate transmission for the first time, utilize the second total powerstation to survey the three-dimensional coordinate setting three reflector plates, as follow-up survey
The known control point of amount setting-out work.
A kind of coordinate transmission method for shaft excavation construction that the present invention provides, by using said method, with biography
For the suspension steel wire of system hangs vertical, installation laser alignment telescope, it is possible to be greatly promoted efficiency of construction, simplify construction procedure, adopt
When hanging vertical with suspension steel wire, need to weigh folding and unfolding vertical repeatedly when excavation construction, be also required to the moment avoids steel wire perpendicular simultaneously
Situation destroyed during well bursting work, and the vibrations generation deviation that laser alignment telescope is easily produced by explosion is installed, therefore need
Frequently to carry out the correction of laser alignment telescope, and along with the intensification of the shaft excavation degree of depth, the operation wind of calibration of laser guide instrument
Danger is also gradually increased, and vertical shaft coordinate then can quickly be transmitted also by coordinate transmission method of the present invention accurately
The problems such as the digging measure setting-out of the solution section survey of vertical shaft straight section, out break measurement and lower horizontal section, execute simplifying
Work step is rapid, while improve efficiency of construction, it is also possible to realize vertical shaft lower horizontal section accurately turns to guarantee with lower flat section smooth
Through.
