Description

Technical Field

[0001] The invention relates to the technical field of edge protection in earthwork construction, and in particular to an edge protection device and a construction method in the earthwork construction stage. Background Art

[0002] Falling from height is one of the five major accidental injuries in the construction industry. The most effective measure to solve it from the perspective of the working environment is to set up solid and reliable edge protection. For solid hardened edges such as concrete, such as the edges after the formwork is removed during the main structure construction phase, the edges of stairs, elevator shaft openings, etc., standardized protection can be used to form reliable edge protection by driving expansion screws into the ground.

[0003] In addition, there are various movable edge protections on the market, such as water barriers and foldable plastic protections, but they all have one thing in common, that is, they only have a warning function. Because they are placed on the edge, they cannot resist horizontal thrust and do not meet the requirements of edge protection.

[0004] During the earthwork excavation stage, the stereotyped guardrail cannot be fixed to the soil surface by expansion screws, and cannot have the protective function, and there is a certain risk of tipping over. The movable edge protection itself does not actually have the edge protection function, and various disturbances are large during the construction process, requiring a lot of manpower for maintenance. Therefore, a reliable, easy-to-operate, and cost-effective edge protection facility is needed to provide firm and reliable protection during the earthwork excavation construction stage.
