Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit protection, in particular to a safety protection device for a construction foundation pit. Background Art

[0002] A construction foundation pit is an earthen pit excavated at the designed foundation location according to the base elevation and plan dimensions. Construction foundation pit protection measures primarily include improving the foundation pit project's safe operation system, implementing technical measures to reduce and control personnel in deep foundation pits, installing protective railings and water barriers, controlling pit-side loading, and establishing safe passageways. Construction fencing is a facility used to isolate a capital construction site from the external environment, creating a relatively enclosed space. It can be constructed from various masonry materials or formed panels to ensure safety and order on the construction site.
