Speed-up Skills of Total Station Leveling

1, pick up the tripod until the time is roughly equal; Install the instrument and tighten the connecting screw-10 second.

2. Aim the optical observer (or hammer ball) at a known point. The key point is that a tripod does not move, the left and right hands hold a tripod leg respectively, and the eyes are aimed at the observer. After basic alignment, hold the tripod steady-10 second.

3. Adjust the centering deviation by the instrument angle screw for -3 seconds.

4. Adjust the tripod so that the bubble is centered on the circular level. Just adjust the two tripods near the car body-10 second.

5, adjust the intermediate tube liquid level bubble -3 seconds.

6. Loosen the connecting screw of the instrument, accurately translate the instrument to the center again, and tighten the screw for -8 seconds.

7. Finally, adjust the horizontal bubbles in the test tube for n times -3n seconds.

8. The total time is about 47 seconds. Even if the alignment accuracy is very high, the alignment and leveling can be completed in about one minute after n times.

Extended data

1, the correct method of leveling with total station and bubble correction of level;

(1), Erection: Erect the instrument on a stable tripod and tighten the central screw.

(2) Rough leveling: Look at the circular bubble (the accuracy is relatively low, generally 1 min), and rotate the three foot screws of the instrument respectively to roughly level the instrument.

(3) Fine leveling: make the tubular level (or long bubble tube) on the sighting part of the instrument parallel to any pair of foot screws, and rotate the foot screws to center the bubble (it is best to use the left thumb method, that is, the left and right hands rotate the two foot screws at the same time, and the two thumbs move in opposite directions, and the direction of the left thumb is the same as that of the bubble tube. )。

(4) Then, rotate the sighting part by 90 degrees, and rotate the other foot screw to center the bubble in the long bubble tube.

(5) Inspection: rotate the aiming part of the instrument for another 90 degrees. If the bubble in the long bubble tube is still in the center, it means that it has been leveled; If there is any deviation, please repeat step.

(6) In general, it is good to repeat 1 ~ 2 times.
