Description

Quick Stakeout Method for Total Station

technical field

The invention belongs to the technical field of surveying and mapping, and in particular relates to a rapid stakeout method for a total station.

Background technique

The total station, that is, the electronic total station (Electronic Total Station), is a high-tech measuring instrument integrating light, machinery and electricity. ), height difference measurement function in one surveying and mapping instrument system. It is called a total station because it can complete all the survey work on the station once the instrument is placed. It is widely used in precision engineering measurement or deformation monitoring fields such as large-scale buildings on the ground and underground tunnel construction.

Stakeout refers to marking out the position designed on the drawing in the field. At present, when using a total station for stakeout, firstly use the stakeout angle to determine the direction of the collimation axis of the telescope, and then move the mirror back and forth along the direction of the collimation axis to achieve accurate stakeout. During the stakeout operation, it is difficult to move the mirror back and forth strictly along the collimation axis. It is necessary to repeatedly adjust the position of the mirror left and right to keep the mirror moving in the direction of the collimation axis, resulting in low stakeout efficiency.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a fast, convenient and accurate method for fast setting out of a total station.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a method for rapidly setting out a total station, comprising the following steps:

(1) First install the laser transmitter on the telescope of the total station, set the first reflector on a fixed rod, and adjust the direction of the laser transmitter to emit laser light to be consistent with the collimation axis of the telescope;

(2) According to the coordinates of station A, backsight point B and the coordinates of point C to be set out, select station A and backsight point B on the site, install a total station at station A, and place a tripod at backsight point B And set the second reflector on the tripod, the telescope of the total station and the second reflector are centered and leveled;

(3) Input the coordinates of station A, backsight point B and point C designed on the drawing into the total station respectively, and the total station calculates the stake-out angle α and stake-out distance d;

(4) Rotate the telescope and laser transmitter of the total station, the rotation angle is equal to the stakeout angle α, then brake and fix the telescope and laser transmitter;

(5) Place the first reflector in the direction of the collimation axis of the laser transmitter, and then a person stands at the total station and directs the person holding the fixed rod through the telescope, and the person guides the first reflector along the laser beam Move back and forth in the indicated direction, and the light emitted by the laser transmitter always shines on the first reflector during the movement;

(6) By observing the total station, when the horizontal distance between the first reflector and station A is equal to the stakeout distance d, stop moving the first reflector, and the orthographic projection of the reflector on the ground is the precise position of point C to be staked out , so as to realize the accurate stakeout of point C to be staked out.

Adopt the above-mentioned technical scheme, the present invention utilizes total station to carry out lofting, at first install laser emitter on the total station, measure the stake-out angle, then determine that the direction of telescope line-of-sight axis is consistent with the laser indication direction emitted by laser emitter, and then Move the first reflector back and forth along the laser pointer direction of the laser transmitter to achieve precise stakeout.

The coordinates of station A and backsight point B are known, the stakeout angle α is the angle of ∠BAC, and the stakeout distance d is the horizontal distance between station A and point C to be staked out.

In the invention, a laser emitter is arranged on the total station telescope, and the direction of the emitted laser light is consistent with the collimating axis direction of the telescope, and the reflector is moved back and forth along the direction indicated by the laser light to realize precise stakeout. When using this method to stake out, you only need to move the reflector back and forth along the direction indicated by the laser, without repeatedly adjusting the position of the reflector left and right, the stakeout is accurate and the stakeout efficiency is extremely high.
