Description

Technical Field

[0001] The utility model relates to the technical field of earthwork construction, in particular to a protection device for earthwork excavation construction. Background Technique

[0002] The earthwork excavation construction mainly includes the following steps:

[0003] On-site survey and planning: Determine the geological conditions and construction plan of the excavation area and conduct topographic surveys and explorations.

[0004] Site cleaning: Remove vegetation, debris and topsoil to prepare for excavation.

[0005] Excavation operation: Use mechanical equipment such as excavators and loaders to excavate soil and rocks, ensuring that the excavation is carried out according to the designed depth and width.

[0006] Transportation and disposal: Transport the excavated earthwork to a designated location or carry out landfill and stacking.

[0007] Backfilling and leveling: After the construction is completed, backfill and level the excavated area to prepare for subsequent construction or restore the ground.

[0008] Earthwork is the general term for earth and rock, that is, soil and rock. The measurement unit is generally cubic meters. Earthwork projects include all aspects of earthwork excavation, filling, transportation, as well as drainage and dewatering. Positioning refers to the positioning by professional surveyors according to the building planning positioning map, forming at least 4 positioning piles at the construction site, and finally using a setting-out tool for setting out. The positioning tool is a total station or a theodolite with higher precision.
