1. measurement: according to the design requirements and construction drawings, measure the subgrade to determine the forming range and elevation of the subgrade.
2. Calculation: According to the measurement results, calculate the area and volume of subgrade and determine the engineering quantity of subgrade shaping.
3. Cleaning: Remove the sundries and garbage on the subgrade to ensure the surface of the subgrade is clean.
4. Shaping: Shaping the road bed, including filling, excavation and compaction, to ensure that the road bed is smooth and firm.
5. Acceptance: Acceptance of the trimmed subgrade to check whether the smoothness and slope of the subgrade meet the requirements.
6. Record: Record the engineering quantity and acceptance results of subgrade shaping, and prepare the corresponding engineering quantity list and acceptance report.
In a word, the calculation rule of subgrade shaping engineering quantity is to determine the engineering quantity of subgrade shaping through measurement, calculation, cleaning, shaping, acceptance and recording according to the design requirements and actual situation, so as to ensure the quality and safety of subgrade.
