What types of earthworks are there?

Common earthworks include: The site is flat ； Excavation and backfilling of foundation pits, foundation trenches and pipe trenches ； Excavation and backfilling of underground projects (civil air defense projects and basements and deep foundations of large buildings) ； Floor filling and rolling, etc. Earthwork construction includes the main construction processes of soil excavation, transportation, and filling, as well as preparation and auxiliary work such as site cleaning, surveying and setting out, construction drainage and precipitation, and soil wall support. Earthwork construction features, including: Wide range, large quantity, high labor intensity ； Construction conditions are complex ； There are many influencing factors. Engineering classification and engineering properties of soil: Earthwork construction uses soil as the construction object, so you should be familiar with the engineering classification and engineering properties of soil. There are many ways to classify soil. The engineering classification of soil divides soil into eight categories according to the difficulty of soil excavation. The engineering properties of soil mainly include the looseness and permeability of soil, as well as the moisture content and compactness of soil.
