Detailed steps for total station highway construction surveys

1.Check the design drawings.

2.Find out the defects in the design and submit it to the design department.

3.Measure the design pile in the early stage, and accept the control pile.

4.The first wire measurement of the construction unit, the first joint measurement of the leveling point.

5.The results will be submitted to the supervisor for inspection.

6.After passing the inspection, it can be used for construction.

7.With the acceptance results, put the middle line of the road, the red line, the side pile, the protective pile, and the infill pile lead point.

8.Measure the elevation of the original ground, check whether the elevation of the original ground of the anti-excavation or subgrade filling given by the drawings is too big, if it is too large, it is necessary to pass 9The project manager shall declare the change of engineering quantity, submit it to the supervisor for inspection and signature, and then submit it to the owner for approval.

10.Normal construction, each layer of subgrade soil construction, double pile, elevation.

11.Every 3 months, check the original elevation points and traverse points.

12.Before the completion of the project, and the supervisor again jointly measure the traverse points and elevation points, out of the data, ready for acceptance. Restore the middle pile side pile.

13.If there is a pavement construction unit, the data of each point will be handed over to the pavement construction unit to ensure that the pavement is smoothly connected.

14.After completion, cooperate with the supervision and quality inspection station to accept the geometric dimensions and elevation.

At this point, the basic traffic engineering survey work was completed.

Dear Hello I'm glad to answer for you: Total station measuring point operation steps A: Dear Hello Total station measuring point adopts polar coordinate method:

First, a total station (leveling, centering) is set up at a known point and the height of the instrument is measured. Set the coordinates, elevation, instrument height, addition and multiplication constants and meteorological corrections of the station. and enter the coordinates, elevation, and prism height of another known point.

It is desirable to have a third known point correction. After that, you can start to measure the distance and horizontal angle of the unknown point to obtain the coordinates and elevation. The measuring point refers to the control point where the instrument is erected, and the rear view point refers to the control point used for orientation.

Before doing the surveying and mapping work, it is necessary to determine the coordinate system to be used, and the coordinate system in the field is the control point; Lofting is to find out and mark the existing coordinates on the spot, so the coordinates of the control point need to be provided by Party A, and it is impossible to assume it by itself. The measuring point refers to the control point where the instrument is erected, and the rear view point refers to the control point used for orientation. Of course, if the accuracy allows, it can also be substation, and then the coordinates of the measuring station are the coordinates of the branch station where the instrument is now erected.

What kind of data are the levels and total stations used in construction projects used to measure?

The total station traverse measurement steps are not complicated, the following explains the detailed measurement method, the specific steps are as follows:

1. After arriving at the designated observation point, first of all, adjust the legs of the total station smoothly, and observe the position of the disc of the finger (red box) in the figure, as long as the inside is kept in the center position.

2. The next step is to adjust the upper part of the total station to keep it balanced, and observe whether the middle ball located in the red frame is in the middle, and it meets the requirements if it is in the middle.

3. Adjust the position of the red frame in the figure again, rotate the knob with your fingers, and be careful not to touch the bracket on the lower side, so as not to readjust the bracket.

4. When the upper part is adjusted, then press the main menu button, follow the prompts on the display to perform the next operation, and select lofting.

5. The next thing is to observe and adjust, use the knob to adjust, this time the part to be adjusted is the lens, pay attention to the lens to be able to see clearly.

6. Finally, you can read and record, here we should pay attention to the flexible use of front and rear view, and the rest is to put the anti-rod point. In this way, the total station wire measurement is complete.

First, the total station is set up.

1. The total station is placed on one control point (measuring station), leveled and centered, and the other control point (rear view point) is erected with a prism;

2. Press the MENU button, press F1 (data acquisition), enter the coordinates of the measurement station and the height of the instrument, and click Next;

3. Enter the coordinates of the backsight point.

4. The instrument aims at the prism and clicks to measure. There are three options for measurement: angle, distance, and coordinates.

If you select a measured coordinate, you can determine whether there is any error or error by comparing the measured coordinates with the coordinates of the backsight point. After the comparison, if the gap is not large, the orientation is completed. If the difference is large, check the point coordinates, point position, etc., and then repeat the steps.

2. Mapping. 1. The mirror technician erects a prism at the feature points of the terrain features, and must tell the instrument operator the current prism height through the intercom;

2. The instrument operator enters the prism height, illuminates the prism, clicks to measure, and saves the coordinates.

3. The draftsman or mirror artist draws a sketch (or the instrument operator prepares the point ** or changes the point number according to the terrain features) to clarify the relationship between the feature points of the terrain features.

4. After the mapping is completed, export the data and use CASS to make the map.

3. Precautions.

1. Note that the actual prism height is consistent with the input prism height;

2. The instrument needs to be redirected when the power is off;

3. Set up to two transfer stations for points that cannot be seen.

Lofting method: according to the known two coordinate points to the total station orientation, and then enter the coordinates of the point to be placed, the total station will display the angle and distance, you rotate the total station, so that the display angle is close to zero, and then take the prism along the lens to point the displayed distance, use the total station to aim at the mirror, point measurement, look at the angle and distance error of the display, and constantly adjust. The distance error is 1-2mm, and the angle difference is +-(1-2) seconds.

Total station coordinate lofting, construction line surveyor to take you to use the total station.

Define the horizontal alignment first, that is, draw the path you want in the total station first.

Then stake out the line according to the station, and put out the point you want to stake out according to the station number, the left pile, the center line of the right pile, or something.

These things are rough, if you want to be specific, you can copy the keywords in this Baidu yourself. Too lazy to write.

Whether to attach or close the wire, the measurement of the attached wire is to measure from the known points (control points) one by one, and finally there is no need to return to the original point. Closed traverse measurements are taken from known points and finally back to known points, forming a closed loop.

The total station traverse measurement steps are as follows:

1. Measure each angle and distance;

2. Calculate the internal business, calculate the closing difference, and then if the limit is met, the reverse number will be distributed according to the number of inner angles;

3. Calculate the corrected azimuth;

4. Coordinate increment calculation;

5. Obtain the coordinates of each point.

The total station, that is, the electronic total station, is a high-tech measuring instrument integrating light, machinery and electricity, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, flat distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the artificial optical micrometer readings with automatic recording and display of the readings, which simplifies the operation of angle measurement and avoids the generation of reading errors. Because it can complete all the measurement work on the station by placing the instrument at one time, it is called a total station.

It is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale above-ground buildings and underground tunnel construction.

Start the measurement from the known point, no matter how many unknown points in the middle, and finally measure to the starting known point.
