What are the main contents of earthwork?

Earthwork is one of the main projects in building construction, including excavation, filling, transportation, drainage and precipitation of all earth (stone) sides. In civil engineering, earthwork includes: site leveling, subgrade excavation, civil air defense engineering excavation, ground filling, subgrade filling and foundation pit backfilling.

To arrange the construction plan reasonably, try not to arrange it in the rainy season. At the same time, in order to reduce the construction cost of earthwork and implement the principle of not occupying or occupying less cultivated land and being beneficial to land reclamation, it is necessary to formulate a reasonable earthwork allocation plan and make overall arrangements.

Earthwork can be divided into permanent earthwork and temporary earthwork according to its service life and construction requirements, but it is required that both permanent earthwork and temporary earthwork have sufficient stability and compactness to make the engineering quality and artistic modeling meet the original design requirements. At the same time, the relevant technical specifications and the requirements of the original design must be observed in the construction to ensure the stability and durability of the project.

Extended data quality standard

1, the soil quality of column foundation, foundation pit and groove foundation must meet the design requirements, and no disturbance is allowed.

2. The treatment of fill base must meet the design requirements and construction specifications.

3, filling column foundation, foundation pit, trench, trench backfill material must comply with the design requirements and construction specifications.

4. The backfill of fill, column foundation and pipe trench must be layered and dense according to regulations.

5, earthwork allowable deviation and quality inspection standards, should comply with the relevant provisions.
