How to measure the earthwork calculation method of white dove grid

1. Conduct on-the-spot investigation on the investigation area, and collect information such as ground topography, landforms and vegetation.

2. According to the field investigation results, a grid network was established in the survey area.

3. Set a measuring point on each grid, and measure the ground elevation with measuring instruments (such as total station and level). Record the measurement results in the measurement table.

4. Determine the design elevation according to the engineering requirements.

5, according to the grid, ground elevation and design elevation, calculate the excavation amount of each grid.

6. Accumulate the earthwork volume of each square to get the sum of earthwork volume within the specified range.

7. According to the calculation results, the distribution law of earthwork volume is analyzed, which provides a basis for engineering design, construction and management.
