It is suggested to study systematically in the surveyor training institution organized by the local construction committee, and follow the engineering survey engineer in class in work practice to improve their survey professional level.
1, learn the basic knowledge of survey, master the layout principle of traverse and elevation control network, and the requirements of traverse grade. Familiar with adjustment calculation, plane polar coordinate and triangulation indoor calculation.
2. Practice the correct erection method of measuring instruments and master the rapid erection of instruments under various terrain conditions.
3, according to the requirements of the project scale and nature, combined with the construction specification, determine the construction control network layout implementation and measurement methods, and prepare the measurement scheme.
4. Determine the construction control network in combination with the positioning conditions (plane coordinates and elevation) given by the design, make adjustment according to the traverse level until the control requirements are met, and set out the pile points with the control network as the known condition. The indoor and outdoor work of measurement shall be carried out by more than two people at the same time, one person shall calculate and measure, and the other person shall recheck. Ensure accurate positioning.
Measure the displacement of buildings and structures as required.
Main instruments: high-precision total station, DS0 1 level, steel ruler (condition check), tower ruler, etc.
The measurement business is not accomplished overnight, so it is necessary to learn the theoretical knowledge of measurement and be familiar with the use of related measuring instruments. Carry out survey work according to engineering practice. Diligent in study, practice and inspection.
