What is the job of earthwork?

Earthwork is one of the main types of work in building construction, covering a series of construction operations related to earthworks. Earthwork includes earthwork excavation, filling, transportation, drainage and precipitation.

Earthwork is often the initial stage of building construction, which lays the foundation for subsequent projects. Earthwork involves changes in the ground, including digging soil or stones to create the required terrain, leveling the site or forming slopes. This process requires earthwork workers to have rich experience and professional skills.

Earthwork is mainly used for building infrastructure, such as roads, bridges, basements and building foundations. The construction process of earthwork is very complicated, which requires careful design and construction to ensure the safety and firmness of the building.

The concrete process of earthwork construction includes: firstly, carry out earthwork survey and design to determine the scope, depth, width and compressive strength of earthwork; Then excavate according to the design, clean up the earthwork, screen the soil, and install the earthwork fence at the correct position; Check, test and adjust earthwork to ensure the safety and stability of the building.

Engineering characteristics

The bulk density of soil is kg/m3, which directly affects the construction difficulty. The greater the unit weight, the more difficult it is to dig. In earthwork construction, soil is divided into loose soil, semi-solid soil and hard soil, and construction technology and quota should be formulated according to specific soil types.

Natural inclination of soil (angle of repose) Natural inclination of soil, expressed by stability, is formed by natural accumulation of soil and surface after settlement and stability. In engineering design, in order to make the project stable, the slope gradient value should refer to the natural inclination value of the corresponding soil, and the natural inclination of the soil is also affected by its water content.
