Description

Technical Field

[0001] The invention belongs to the technical field of high slope engineering equipment, and more specifically, particularly relates to a high slope earthwork excavation protection safety device. Background Art

[0002] At present, in the construction of high slope projects, high slope earthwork excavation projects are often encountered. Due to its high height, the stability of the soil or rock during the excavation process is poor. Once the soil or rock slides or collapses, it will pose a serious threat to the personnel and equipment at the construction site. In mountain road construction, if the workers at the high slope excavation site do not have adequate protection, they are easily hit by the sudden rolling stones, resulting in casualties.

[0003] Traditional protective measures are often simply to set up protective nets. This type of protective net may be effective in dealing with small-scale soil and rock slides, but its protective ability is very limited for large-scale soil and rock collapses or in special circumstances such as strong winds and earthquakes. Existing protective devices lack the function of reinforcing soil and rock on the surface of high slopes. At the same time, during the excavation process, the soil and rock on the surface of high slopes are easily loosened due to factors such as vibration and rain erosion. Simple protective nets and guardrails cannot fundamentally solve this problem, cannot warn of possible collapses, and cannot handle rainwater and gravel in a timely manner, thereby increasing their driving force on large volumes of soil and rock, causing safety hazards such as mudslides.
