[0002] Earthwork is a very common process in civil engineering, especially in infrastructure construction. The purpose of earthwork is to change the terrain by excavating and filling to meet the needs of the construction project. However, earthwork is a high-risk job with certain safety risks. In order to ensure the safety of workers and the smooth progress of the project, a series of safety protection measures must be taken.

[0003] Common safety measures include: site identification and isolation, excavation hole and tunnel support, and pipeline identification and protection. Site identification and isolation involves setting up guardrails and notice boards around the earthwork construction site to clearly mark the construction area, reminding people to pay attention to the construction area and preventing outsiders from entering. The construction area is isolated to ensure that unauthorized personnel cannot enter the construction site at will.
