Highway Surveyor Help!! Experts in Highway Surveying Come in !!

I also worked as a surveyor, and I didn't know anything at first, but after two months of study, I was able to do it myself.

To do this business, you need to know what knowledge points are needed, 1. Trigonometry. software and professional software that you are familiar with.

3。Scientific Computers. These are of great help to you.

It's pretty quick to learn and use at the same time. It's not as hard as you think! Step up your game!

If you can endure hardship, you can do it!

Those who do measurements should be bold, careful, and thick-skinned!

Bold: Because measurements are basically done in the field!

Careful: calculation, pay-off, etc. are all meticulous work!

Thick-skinned: often exposed to the sun and wind! (I get a lot of tans like Africans!) 97 measure it.

Measurement is a very hard thing, but measurement is the foundation, it is very helpful to have a comprehensive understanding of engineering, more than those who experiment, and it is also a technology that requires in-depth research and practice.

Highway surveying is nothing more than exploration, design, and lofting, and a lot of knowledge is related to mathematics, if you want to be a good surveyor, you must learn mathematical knowledge. It's a matter of people, only you have the patience to strictly follow the measurement specifications. There should be no problem.

I am engaged in high-speed rail surveying, and I have also measured highways! I will tell you the ways and means of the scene, I hope it will help you!

1. For the students who come out of Gangcong School, they first need to understand the most basic principles of measurement, combined with the knowledge in the books, and then they are: the basic operation of level, total station, GPS (if any), the basic calculation of elevation, coordinates, earth and stone, and the lofting method of excavation line, central axis, slope over-under-excavation, and tunnel over-under-excavation.

2. When you first enter the site, you need to hand over the pile position (level base point, control network base point) with the design institute, and then review the point of the design institute and its review data to the supervision for approval, and finally carry out land acquisition and demolition, lofting of the land acquisition line, and lofting of the important points of the excavation line, the center line pile and its structure.

3. In the construction process, it is necessary to carry out control point encryption, pile position detection and review, lofting approval, etc.

4. When the project is completed, it is necessary to measure the pavement elevation and other acceptance in combination with the on-site supervision of both parties A and B.

A few suggestions for you: talk less, do more, ask more, and report to important leaders when they have the opportunity to contact them.

You're not getting started yet.

Road surveying is not something that a level can solve. Now all with a total station.

To put it simply: the road has a middle line. It is mainly composed of straight lines, circular curves, and spiral curves (circular curves with unequal radii everywhere).

The method is to calculate the coordinates of the lofting site according to the drawing, and then type out the coordinates through the total station. The coordinate calculation group should use a calculator program. Measurement is not an easy industry either.

It's still early. You'll know after two months with a master.

It's hard to say.

First of all, lofting, set up the pile, the side pile, and at the same time carry out the elevation remeasurement of the original ground, that is, the elevation of the pile and the side pile, and then carry out the internal work, draw the original ground section drawing, and calculate the earthwork quantity with the hat method, if the error with the design engineering quantity exceeds a certain range, it is necessary to declare to the supervisor and carry out tripartite joint measurement;

Then, mark the construction scope on the site with white ash, carry out the clearance, then continue to lofting the pile, the side pile, carry out elevation measurement, mark the filling edge with white ash, and carry out such work from the corresponding elevation for each layer of filling in the future;

There are a lot of engineering surveys, including bridge surveys, roadbed surveys, tunnel surveys, the main task is to move to the ground according to the coordinates of the things on the drawings, you are talking about a part of the measurement of the roadbed, the middle pile and side installation of the roadbed, if you want to learn to measure well, in fact, it takes a lot of effort, diligent study and more questions. Start from the coordinates of straight lines, then to circular curves, and then to ease curves, step by step. Finally, there are complex curves that combine these simple curves, and any engineering measurement is a combination of these simple curves.

Have you measured the elevation of the earth's surface?

Put out the line first, and put out the middle line and curb line.

Then measure the ground elevation.

However, it is determined that the excavation edge line should be counted one by one. For example, if you want to excavate the section of 0+800, set the elevation of 0+800 pavement is 30, and you measure the elevation of the original ground of the 0+800 road edge line is 55, that is, you want to excavate 25 meters downward

of slopes, such as yes slopes. Then from the roadside pile outside the measurement of meters (here to pay attention to the direction, from the direction of the vertical line of the road line) to determine the excavation point, and then measure the elevation of the excavation point, here relative to the roadside point, we have just measured the point, may be high, may also be low. Compare, subtract the elevation of the curb from the side pile meter from the measured first, if it is positive, it will move to the middle of the road, and if it is negative, it will move to the outside of the road.

The amount of movement is (difference * e.g. if the elevation at the meter measurement is 58 meters, then 55-58 3 meters, 3 * meters. That is, to the direction away from the center line of the road, it is the correct excavation line.

Of course, this process varies according to the slope of the excavation site, and the correct excavation point can be determined in two to three times. Then there is earthwork excavation is not a precision engineering, and the excavation point has a mistake of more than ten centimeters can also meet the construction requirements. Okay, you can take a look at it again, I hope it will catch you.

First of all, it is necessary to determine the elevation of the variable slope point, and then according to your measured elevation, you can judge which section the point is in, and then find out what is the design half width under the elevation, and then use the measured coordinates to calculate the measured width, and the comparison with the design, is this idea, now the measurement is generally reversed, if the lofting structure needs to use the coordinates to put the point. Wish.

fs = under the root number (fx*fx+fy*fy)=, k=fx 620=1 3048

The answer is d as a question, 1 3048 is okay, if in engineering, such accuracy is too bad.
