Engineering survey retest requirements?

What are the requirements for retesting of engineering survey?

There are no regulations on whether to use the same instrument, but the personnel level, instrument level, measurement method, and result accuracy during the retest cannot be lower than the initial test level. Requirements for engaging in engineering surveying

Vision Requirements for Engineering Surveyors

There are no requirements. During our internship, there was a person who could do very well despite having a disease in one eye. If you are observing with myopia, you can do it without glasses. Looking for engineering survey PPT

Go to Baidu - Library - "Enter Engineering Survey" and click search. There is a PPT option below the search bar.

There are many PPTs in it. for your information.

Please adopt~~ Request for engineering survey wire measurement! urgent!

Read the following national specifications carefully:

GB50026-2007 Engineering Surveying Specifications

GBT12898-2009 National Third- and Fourth-Class Leveling Specifications

Engineering Survey

First calculate the total number of measuring stations n=50

Then calculate the total number of height differences m=3.315

Then Fh=h measurement-h management (h management =68.623-65.376=3.247)=3.315-3.247=+0.068 fh capacity=0.085 greater than 0.068 consistent

Correction number=average distribution of reverse signs (-Fh*n/n total=-0.068*nth station Number/50) The order is -0.011 -0.016 -0.019 -0.022

The corrected height difference is equal to the correction number of each station plus the original height difference, such as the first station = -0.011+1.575.. ...and so on

Elevation = the elevation of the previous station plus the corrected height difference between this station and the previous station

The final auxiliary calculation of fh capacity is very simple n=50 Bring in fh capacity = 0.085

This question needs to be solved using the line of sight method

HA+a=HB+b

b=HA+a- HB=15.023+2.340-16=1.363m

(1) Calculation of main point measurement elements:

Tangent length T=R*tan(α/2)=78.447m

Curve length L=лRα/180°=150.709m

External vector E=R[sec(α/2)-1]=13.568m

Curvature difference q=2T-L=6.185m

(2) Main point chainage calculation

ZY (straight circle point) chainage=JD chainage-T=K2+ 182.321-78.447=K2+103.874

QZ (center point of curve) station number=ZY station number+L/2=K2+103.874+150.709/2=K2+179.228

YZ (circle straight point) station number = ZY station number + L = K2 + 103.874 + 150.709 = K2 + 254.583

To find a good job

First, look at yourself, secondly, look at society, and thirdly Good harvests can only come from the combination of fate and opportunity

Not having to worry about finding a job is not necessarily a good job

Just don’t let people think badly of you when applying< /p>

After all, you are being tested and there is no standard answer

Hehe, what about this industry? Relatively speaking, it is relatively good, because currently there are still relatively few people measuring, but it is still very tiring. If you love beauty, you should not come here, haha

Because this measurement is basking in the sun It's normal to be exposed to wind and rain, especially in summer. It's so damn tanning that you'll get tanned in 2 months, but the salary is still good. If you're good at it, you'll still get 1W. If you learn how `You won’t be tired anymore. If you accept two apprentices, you will have fun for a day, haha. `Standing for a day when measuring is the same as standing still, haha.

Every line has a good side, there are Your efforts will be rewarded,

You can go for an internship and get a feel for it, then you will know.

Come on!
